This plan is primarily an update to the City of Renton's (City's) 2005 Plan_ The City of Renton water system identification number is 71850 L. The purpose of this Plan is to develop a long-term planning strategy for the City's water service area. Updated every six years, the Plan evaluates the existing system and its ability to meet the anticipated requirements for water source, quality, transmission, storage, and distribution over a twenty-year planning period. Water system improvement projects have been developed to meet the changing demands of regulatory impacts, and population growth, as well as infrastructure repair and replacement_ The Plan also identifies planning level costs of the improvement projects and provides a financial plan for funding the projects. A State Environmental Policy Act (SEPA) Checklist and determination of non -significance (DNS) has been prepared for this Plan. The City anticipates this Plan does not have probable significant adverse impacts on the environment in accordance with the DNS under WAC 197- 11-340(2). The SEPA Checklist and DNS are included in Appendix A. This Plan is required to meet state, county, and local requirements. The City will submit this plan to the DOH, the Department of Ecology (DOE), King County, adjacent utilities, and local governments as part of the Agency Review process. See Appendix B for the Comment Letters. The Adopting Resolution will be included in Appendix C, upon Plan approval by the City Council. Introduction The City is located within King County at the southeastern end of Lake Washington. Its water system provides service to an area of approximately 16 square miles that is largely coincident with the city limits. The water distribution system serves the valley floors and parts of five surrounding hills: West Hill, the Highlands, Scenic HIII (also known as Renton Hill), Talbot Hill, and Rolling Hills. The City currently serves customers within an elevation range of 11 feet to 476 feet. The City's water system provides service to a full-time residential population of approximately 54,000, approximately 20,000 temporary and transient users, and approximately 28,000 regular non-residential users. In addition, the City supplies water on a wholesale basis to Skyway Water and Sewer District through a single metered connection. The City's retail water service area (RWSA) is bordered by nine adjacent water systems. It is unlikely that Renton's RWSA will change much in the future due to the geography of the surrounding areas and the fact that all of the surrounding areas are currently served by other water purveyors. The only possible change to the City's RWSA boundaries in the future is an adjustment to the boundaries to include the area "Future Retail Water Service" shown in Figure ES.1. Copies of service area agreements between the City and the adjacent water purveyors are included in Appendix D and summarized in Chapter 1.

The City's water distribution system consists of more than 1.6 million feet of pipeline. The water system facilities are shown in plan view in Figure ES.2. Chapter 2 provides a description of each facility and any major changes since the last plan update. Water supply sources include five wells (RW -1, RW -2, RW -3, PW -8, and PW -9) and one spring (Springbrook Springs) that are used for normal supply. The City continues to gather data for the Maplewood well field (Wells PW -11, PW -1 2, and PW -17) for the purpose of obtaining perfected water right certificates for the wells. In addition, the City is a wholesale customer of Seattle Public Utility (SPU). The City has six metered interties with the SPU transmission mains_ As a result of Renton's topography and geography, the City has 15 hydraulically distinct pressure zones. Pumping throughout the water system is accomplished by nine online booster pump stations (BPS) and two standby BPS that are located throughout the City. Currently there are ten reservoirs in the system, strategically located to provide adequate equalizing and fire flow reserves for all pressure zones. Pressure reducing valves (PRVs) are used to supply lower pressure zones from higher pressure zones that contain water storage reservoirs. The City has ten interties and three additional emergency interties.

The City's future water demand is estimated for the RWSA based on current use and anticipated growth within the RWSA, utilizing data provided in the Puget Sound Regional Council's (PSRC's) Population, Households, and Employment Forecast database. Chapter 3 summarizes the current and projected demographics; Appendix J provides a detailed description of the methodology used for the projections. In general, there is very little vacant land within the City's current RWSA. Therefore, the growth capacity within the City's RWSA is limited. The majority of future growth is projected to occur within the Regional Urban Center and the Sunset Area Community Planned Action redevelopment boundaries. The City's historical production data was used to calculate the Average Day Demand (ADD) and Maximum Day Demand (MDD) for each year from 2004 to 2009, as displayed in Table ES. 1. This data was used to determine that the average MDD/ADD peaking factor is 1.83. Table ES.1 Historical Average and Maximum Day Demand Annual Average Day Max. Day Date of Max. Day/Avg.

Historical data from 2004 to 2009 indicate an average ERU water use of 171 gallons per day (gpd) for the City of Renton. Projected ERUs were determined using the growth projections described in Chapter 3. The projected ERUs do not include distribution system leakage, (DSL) miscellaneous water use, or wholesale customer demand. However, ADD and MDD values do include DSL, etc. The ADD and MDD projections were utilized in the system and supply analysis.

Wholesale demand projections for Skyway from the 2005 Skyway Water and Sewer District Comprehensive Plan - Water and Sewer Systems. 3. Other Authorized Consumption is estimated to be 0.57 percent of the total system demand. 4. Unaccounted-for Water is assumed to be 17.8 percent of total system demand. 5. MDD = 1.83 x ADD (Skyway maximum day to average day peakingfactor is 3.34). DSL fluctuated between 15.8 percent and 20.2 percent of the total City production between 2004 and 2009, with an average of 17.8 percent. The demand projections in Table ES.2 assume that unaccounted-for water will continue to account for roughly 17.8 percent of the total City demand through year 2071. Chapter 4 includes a discussion of the actions to be taken by the City to help meet the ten percent leakage goal. Chapter 3 also presents a range of demand projections that was developed to evaluate the impacts of varying build -out growth assumptions, DSL, and impacts of climate change. Water Use Efficiency and Conservation Pian Chapter 4 presents the City's Conservation and Water Use Efficiency Plan for the next six years. During this period, the City will join the Saving Water Partnership, which will expand the breadth and depth of the City's conservation activities. February 13, 2012 - DRAFT ES -6 pw:lfCarollo7documents/ClienUWA/Rentonl8595AOOldeliverables/ES.docx The Water Use Efficiency (WUE) rule, which was introduced by the Washington State Legislature and came into effect in 2007, establishes that all municipal water suppliers must use water more efficiently in exchange for water right certainty and flexibility to help them meet future demand. The four fundamental elements to the WUE program are planning requirements, metering requirements, distribution leakage standard, and conservation planning and goal setting. Planning Requirements The WUE rule requires the collection of production and consumption data on a regular basis. These are utilized in this planning document to forecast future demand, describe water supply characteristics, to aid in water management decision making, to calculate DSL, evaluate the WUE program, and be submitted to the state in the annual WUE report. Metering As required by the Municipal Water Law, all the City's sources of supply, as well as interties and purchases, are metered with production meters. The City also provides service metering for its customers. All large service meters are tested annually and repaired as needed. Small service meters are repaired or replaced on an as -needed basis. Distribution System Leakage Municipal water suppliers must now meet a 10 percent or less DSL based on a 3 -year rolling average to comply with the WUE standard. Because the City's DSL exceeds 10 percent, a "Water Loss Control Action Pian" was developed (Appendix Q). Implementation of this plan, which began in 2008, establishes compliance with the WUE rule. An additional measure that should contribute to lowering of DSL is the City's implementation of an automatic meter read (AMR) program. A benefit of the AMR program will be to provide more time for operations and maintenance staff to perform maintenance on small, as well as large meters, on a more regular schedule. Conservation Plan Current water conservation planning is governed by the WUE Rule. As a municipal water supplier with more than 17,000 connections, the City is required to implement the five mandatory measures and either implement or evaluate the two others. Table ES.3 presents the mandatory measures and the City's status for compliance. February 13, 2012 - DRAFT ES -7 pw',1iCarollo0ocumentslClient!WAlRenbon78595AOOIDeliverables/FS.doex Table ES.3 WUE Mandatory Measures Must implement the following WUE measures: Status Install production (source) meters Implemented Install consumption (service) meters Implemented Perform meter calibration Implemented 1 ongoing Implement a water loss control action plan to control leakage Implemented 1 ongoing if exceeds 10% Educate customers about water efficiency at least once per Implemented /ongoing year Must evaluate or implement these WUE measures: Evaluate rates that encourage water demand efficiency Implemented Evaluate reclamation Implemented / reviewed Since 1990, conservation programming has included school outreach, a speakers' bureau, fairs, and promotion of regional programs. The addition of the 12 -month water consumption history on water bills was started in 1992. Since 1994, the City of Renton has employed increasingly complex tiered water pricing rates to encourage conservation. Other past and present conservation efforts are explained in Chapter 4. Policies, Criteria, and Standards The City manages its water utility and water system in accordance with established federal and state regulations for public water systems. City policies and standards described in Chapter 5 provide a consistent framework for the planning, design, construction, maintenance, operation, and service of the City's water system and water supply sources. The City's policies are grouped by major categories including: • Service Area. • Water Supply Planning and Management. • Water Main Extension and Service Ownership. • System Reliability and Emergency Management Plan. Fire Protection. • Financial. • Facilities. • Organization. February 13, 2012 - DRAFT ES -8 pw:llCarollolDocumentslClienVWNRenion18545A00lDeliverableslES.docx Water Supply, Water Rights, and Water Quality Chapter 6 describes the City's sources of supply, including the condition and capacity of its sources, the water rights associated with its sources, and the water quality requirements for its sources. This chapter also discusses the City's interties as they are related to its source of supply and provides a summary of Renton's Wellhead Protection Program. Wafer Supply Renton's supply is derived from five water sources: the Cedar Valley Aquifer, Springbrook Springs, the Maplewood Aquifer, the recharge area for Well 5A, and SPU supply interties. For the City's primary supply, it maintains and operates six wells within the Cedar Valley Aquifer and three wells within the Maplewood Aquifer. Water Rights Renton has developed independent water sources in order to maintain greater control over the management and costs of its water supply. The City has 13 water right certificates and five permits. Copies of the City's water rights certificates and permits are in Appendix E. In issuing recent water rights certificates to the City, DOE has conditioned the permits with a limitation on the total withdrawals by the City of 14,809 acre-feet per year (AFY). The City does not anticipate applying for any new water rights or changes to its existing water rights. The installed pumping equipment has the capacity to deliver the water equal to the peak day requirements of the City's system through 2025. During the current planning period, the City anticipates that on infrequent occasions the demand will exceed the instantaneous withdrawal water rights of the Cedar River sources and Springbrook Springs. During these periods, the City plans to meet the demand by purchasing wholesale water from SPU. The City estimates that it will begin to exceed its annual water right of 14,809 acre-feet (AF) as soon as 2031 or as late as 2081. Water Qualify The City's water quality at its supply sources, storage facilities, and within its distribution system satisfactorily meets state and federal requirements on a regular basis. Overall water quality within the system is excellent with only minor aesthetics problems caused by iron, manganese, and hydrogen sulfide. During the last 21 years, the City has upgraded the treatment systems at its Springbrook Springs and all downtown wells. Gaseous chlorine or sodium hypochlorite (Maplewood wells) is added to all of the City's sources for disinfection, and sodium fluoride is also added to prevent dental caries / cavities. Within the next six years, the City plans to provide Wells EW - 3, PW -8 and PW -9, and Springbrook Springs with primary disinfection. The City has implemented a comprehensive and proactive water quality monitoring program. It includes monitoring for operations, regulatory monitoring to meet the requirements of the federal Safe Drinking Water Act, and monitoring to manage the City's aquifers. This program is described in detail in Appendix H of this Plan. The City also has a Wellhead Protection February 13, 2012 - DRAFT ES -9 pw:llCarolkol0ocumerlrlClienVWAIRerlonl8595AOO/Nliverables7ES,docx Plan, which was approved by DOH in December 1999. An updated Wellhead Protection Plan is included as Appendix L. Recommended Water Supply Improvements It is recommended that the City maintain and/or renew its existing intertie agreements with adjacent purveyors as well as pursue additional interties in order to improve reliability and supplement future peak demands. System reliability can be further improved by implementing security improvements and considering installation of new PRVs and other control valves when redevelopment occurs. Additional possible projects for improving supply reliability are aquifer recharge and the use of reclaimed water. King County plans to perform a countywide reclaimed water feasibility study, in which the City will participate, to identify potential reclaimed water users. System Analysis The City's water distribution system was evaluated for deficiencies in the storage facilities, pump stations, and pipelines. The system analysis yielded a number of recommended improvements including pump station, reservoir, pipeline, and pressure zone improvements, as summarized in Chapter 7. Projects to address deficiencies found in the year 2017 are of higher priority than those to address deficiencies in the year 2031. Operations and Maintenance A detailed review of the City's water system operation and maintenance program was performed. The City's water system is maintenance -intensive, with its facilities for pumping, water quality control, and emergency power generation. Chapter 8 describes water system management, operator certification, system operation, the emergency response program, safety procedures, the customer complaint response program, and record keeping and reporting. Capital Improvements Plan Chapter 9 summarizes planned and future water system improvement projects and programs that are recommended in other chapters of this Plan and from other feasibility studies for the City. The improvements are necessary to keep the system in compliance with all federal and state regulations as well as to meet future water demand due to population growth within the City's RWSA. Capital projects are generally categorized into water supply, water quality and treatment, storage facilities, pump stations, water main rehabilitation and replacement, major maintenance, and regulatory compliance programs. Projects identified in the current CIP document are summarized in Tables ESA and ES.5.

The Water Utility operates as an enterprise fund and as such, it must be self-sustaining. Water utility funds are accounted for and budgeted separately, but are managed as a system with other City's enterprises funds in accordance with the City's financial management policies. The City accounts for its water revenues and other funding sources in two main separate funds. Fund 405 is the Operating Fund for the City's Water Utility. Fund 425 is the Construction Fund for the Water Utility for the design, construction, and project management of capital improvement projects. The Finance Department maintains the financial records for the Water Utility. Table ES.6 presents a projection of annual utility revenues, expenses, and fund balances for the next 10 years (2011-2020). Transfers to the capital improvement fund included in Table ES.6 represent anticipated funding needs for projects in the current (2011-2016) CIP. These funds will be updated to reflect the recommendations cited in this plan for future budget and rate projections.

This Plan is largely an updated version of the City's 2005 Plan. The purpose of this Plan is to document changes to the City's water system, to identify required system modifications, and to appropriately outline capital improvements projects to meet future water demands. Maintaining a current Plan is required to meet the regulations of the DOH and the requirements of the Washington State Growth Management Act. This plan complies with the requirements of DOH as set forth in the WAC 246-290-100, Water System Plan. This Plan contains timeframes, which are the intended framework for future funding decisions and within which future actions and decisions are intended to occur. However, these timeframes are estimates, and depending on factors involved in the processing of applications and project work, and availability of funding, the timing may change from the included timeframes. The framework does not represent actual commitments by the City of Renton, which may depend on funding resources available. 1.2 AUTHORIZATION Recognizing the importance of planning, developing, and financing water system facilities to provide reliable service for the existing customers and to sere anticipated growth, the City initiated the preparation of this Plan. In August 2010, the City selected the Carollo Engineers team to assist the City in the preparation of the updated Plan in accordance with applicable rules and regulations governing planning for water utility systems. 1.3 OBJECTIVES This Plan has been prepared to serve as a guide for planning and designing future water system facilities and to assist the City in using its water resources in the most efficient manner possible. Identified in this Plan are system improvements intended to meet the expanding and changing needs of the City. Specific objectives of this Plan are addressed by individual chapters presented herein and include the following: Develop a document that can be updated periodically as additional information on the water system is obtained. Description of Existing System (Chapter 2): Document the existing water system supply, storage, and distribution facilities. February 14, 2012 - DRAFT 1-1 pw:l7CarollolDocumenWClienVWAlRentonl8595A60lDeliverableslChO 1.docx • Planning Data and Water Demand Forecast (Chapter 3): Identify and estimate the effect of future land uses and population trends on the water system. Document historical water use and project future demands based on growth projections. • Water Conservation Program (Chapter 4): Identify the role that water use efficiency will have in reducing future water requirements and how the City's water conservation program will be implemented. • Water System Policies, Criteria, and Standards (Chapter 5): Establish clear policies and criteria relating to water service and within the City's water system. • Water Supply and Water Rights (Chapter 6): Document existing and potential future water supply and water rights, and discuss existing and forthcoming regulatory requirements on the City water system. • System Analysis (Chapter 7): Update the computerized model for analysis of the system. Assess the capability of the existing water system to meet existing and projected future demands, identify water system deficiencies. • Operations Program (Chapter 8): Provide a comprehensive review of operations and maintenance of system facilities. • Capital Improvement Program (Chapter 9): Develop a program of capital improvements, including priorities for design and construction. • Financial Program (Chapter 10): Develop a plan for financial backing of required system improvements. • Prepare an environmental checklist for City Council action on the proposed water system plan. The checklist is to be reviewed by the various City departments for a threshold determination. • Prepare a plan to comply with the requirements of the DOH. 1.4 LOCATION The City of Renton is located within King County at the southeastern end of Lake Washington. Interstate 405 (1-405) runs through the middle of the service area, from its western boundary, up through its northern boundary. The Cedar River divides the City's RWSA between the north and south. Its water system provides service to an area of approximately 16 square miles that is largely coincident with the city limits. The water distribution system serves the valley floors and parts of five surrounding hills: West Hill, the Highlands, Scenic Hill (also known as Renton Hill), Talbot Hill, and Rolling Hills. The City currently serves customers within an elevation range of 11 feet to 476 feet. This range creates a need for at least four separate pressure zones. However, physical barriers such as hills and valleys often prevent the extension of a pressure zone from one location to another. As a result of Renton's topography and geography, the City has 15 hydraulically distinct pressure zones. February 14, 2012 - DRAFT 1-2 pw:NCaroliolDocumentslClienUWAlRentonl8595A00IDeliverables1Ch01 docx the City's RWSA is bordered by nine adjacent water systems: the Skyway Water and Sewer District, Seattle Public Utilities, the City of Tukwila, the City of Kent, the Soos Creek Water and Sewer District, the Cedar River Water and Sewer District, King County Water District No. 90, the Coal Creek Utility District, and the Wasmeta Park Water System. Figure 1.1 shows the City's neighboring water utilities, as well as the RWSA boundaries. 1.5 OWNERSHIP AND MANAGEMENT The City has a City Council—Mayoral form of government. Members of the Council and the Mayor are elected officials. The Mayor is the head of the executive branch of the government and is the chief executive officer of the City government and as such has general supervision over the several departments of the City and over all its interests. Figure 1.2 shows the organization of the drinking water utility. With the exception of the billing function, the operation of the utility falls under the supervision of the Administrator of the Planning/Building/Public Works Department, Mr. Gregg Zimmerman. Some of the City offices that provide support to the operation of the Drinking Water Utility are not shown on the organizational chart. For example, the Human Resources/Risk Management Department provides hiring, benefits, insurance, some types of training and other support to the utility; the Information Services Division provides computer, networking and telecommunications support; and the City Attorney's Office provides legal support. Budgets are formulated by the departments and are presented by the Mayor to the City Council for approval. Expenditures for items in a Council -approved budget are approved by the Administrator, the Mayor or the Council depending upon the amount of expenditure. 1.6 SYSTEM HISTORY The history of the City's system is well documented in the previous Water System Plans prepared for the City by CH2M Hill in 1966, by RH2 Engineering in 1983 and 1990, by the City and RH2 Engineering in 1998, and by the City and RW Beck in 2006. The detailed information presented in those documents is not repeated in this document. For those interested, the 1965, 1983, 1990, 1998 and 2006 Water System Plans are available from the City. However, some of the history of the system is included in this plan for the sake of convenience, details of which can be found primarily in Chapter 2. The City's water system provides service to a full-time residential population of approximately 54,000, approximately 20,000 temporary and transient users, and approximately 28,000 regular non-residential users. In addition, the City supplies water on a wholesale basis to Skyway Water and Sewer District through a single metered connection. The retail water service area (shown in Figure 1.3), includes service to some parts of unincorporated King County. Chapter 2 provides a more detailed description of the development of the water system by facility.

These boundaries were further refined by agreements with the adjacent water purveyors: Skyway Water and Sewer District (CAG -03-197, December 31, 2003), Soos Creek Water and Sewer District (CAG -083-91, August 6, 1991 and CAG -97-164, October 10, 1997), and Cedar River Water and Sewer District (CAG -99- 014, February 8, 1999). The RWSA boundaries are shown on Figure 1.3. It is unlikely that the City's RWSA will change very much in the future because of the geography of the surrounding areas and the fact that all of the surrounding areas are currently served by other water purveyors The only possible change to the City's RWSA boundaries in the future is an adjustment to the boundaries to include the area "Future Retail Water Service" shown in Figure 1.3. This area was originally defined in the Skyway Coordinated Water System Plan and is also described in service area agreement between the City and Skyway Water and Sewer District. The area would only become part of the water service area upon annexation into the City. 1.7.1 Service Area Agreements Copies of current service area agreements are included in Appendix D. The following is a list of the service area agreements that the City has with adjacent purveyors: CAG -03-197 — Agreement between the City of Renton and the Skyway Water and Sewer District for the Establishment of Water and Sewer Service Boundaries, December 31, 2003.

February 14, 2012 - DRAFT 1-10 pw:liCarollo7Dwuments/ClientlWNRentonl8595AOOIDeliverableslCh01 .dc)cx Chapter 2 EXISTING SYSTEM 2.1 SYSTEM OVERVIEW The City owns and operates a multi -source municipal water system, which includes supply, treatment, storage, and distribution of potable water to residential, commercial, industrial, and wholesale customers. Service is provided to an area of approximately 16 square miles and 17,400 retail customers (service connections) and one wholesale customer, Skyway Water and Sewer District, via a single metered connection. The Water Service area is shown on Figure 1.2 in Chapter 1 — Introduction Figure 2.1 presents the water facility locations. Water supply sources include five wells (RW -1, RW -2, RW -3, PW -8, and PW -9) and one spring (Springbrook Springs) that are used for normal supply. These wells are located in Liberty Park and Cedar River Park, pump from a relatively shallow aquifer (Cedar River Delta Aquifer), and are referred to as the Downtown Wells. Well EW -3 also pumps from this aquifer and is available as an emergency back-up only. Well PW -5A, which can serve three pressure zones, is available to use during high demand periods. However, the water from this well, as currently treated, has less than desirable aesthetic quality due to iron, manganese, and ammonia in the raw water. Well PW -5A pumps from a deep aquifer in the Kennydale area of north Renton. The City continues to gather data for the Maplewood wellfield (Wells PW -11, PW -12, and PW -17) for the purpose of obtaining perfected water right certificates for the wells. The primary purpose of this wellfield is to provide an alternate source of supply in the event of the contamination of the Downtown Wells. A secondary purpose of the wells is for additional instantaneous flow during high demand periods. The permits for the wells set the system wide annual withdrawal (Qa) to no more than the existing certificated Qa of 14,809.5 acre feet; i.e., the proposed annual water rights are supplemental, not additional. The wells pump from a deep aquifer underlying the Maplewood Golf Course. The City is a wholesale customer of SPU. The City has six metered interties with the SPU transmission mains, which are available to serve wholesale water to the Renton distribution system. All water consumed in The City's RWSA must pass through a well or spring and potentially several pump stations. Because of this, the City's water system is maintenance -intensive, with facilities for pumping, water quality control, and emergency power generation. Areas within the City's RWSA may have similar elevations, but cannot be served as part of the same pressure zone due to the geography. As an example, the pressure zones in the Highlands area have not been extended across Maple Valley into the Renton Scenic Hill or Talbot Hill areas, even though the elevations served on these two hills are similar. The Cedar River Valley has provided a physical barrier that has precluded joining of February 14, 2012 - DRAFT 2-1 pw:llCarollolDocumentVClienVWNRenton18595AOOiDeliverahle5lChapter MhUdocx hydraulically similar pressure zones. As a result of these physical barriers and the elevation range served, 15 pressure zones are necessary, as shown in Table 2.1. Table 2.1 Pressure Zones by Geographical Area Pressure Zone Serves VLY 196 Valley Floor KD 218, KD 320, HLD 435, and HLD 565 Highlands and Kennydale areas WH 300, EARL 370, and WH 495 West Hill and Earlington areas SH 370 and RH 490 Scenic Hill and Rolling Hills areas WTH 300, ETH 300, TH 350, RH 395, RH Rolling Hills and East and West Talbot Hill 490, and RH 590 areas Figure 2.1, Existing System, shows how water moves horizontally through the system. Figure 2.2 is a hydraulic profile of the system and shows how water moves vertically through the water system. All of the pressure zones are hydraulically interrelated with the lowest pressure zone, the Valley 196 Zone, in the valley floor. Additionally, the Rolling Hills and Highlands zones can be supplied from the Maplewood wellfield (79 Pressure Zone, where 79 is the overflow elevation of clearwell). All supply to the system not consumed in the Valley 196 Zone is pumped to higher pressure zones. It is desirable to have two or more connections (or supply points) within each pressure zone that allow water to move upward to a higher pressure zone, or downward to a lower pressure zone. This maximizes system reliability by providing multiple paths or routes that the water can take when moving between pressure zones. Pumping is accomplished by nine online BPSs and two standby booster stations that are located throughout the City. The water from the downtown wells and the artesian spring is first pumped, or in the case of the spring flows, into the lowest pressure zone in the valley floor, and then is pumped up to the West Hill, Highlands, Renton Hill, Talbot Hill, and Rolling Hills Zones for consumption. Water from the Maplewood wells is pumped from a post-treatment clearwell into the Highlands and Rolling Hills Zones. Water from PW -5A is pumped into the Highlands 435 Zone_ The two standby pump stations, one PRV station, and one metered connection can supply water to the Rolling Hills / Talbot Hill service area from interties with the Seattle Cedar River and Bow Lake transmission pipelines. One intertie (PRV station) can supply water to the Earlington 370 Zone from the Seattle Bow Lake transmission pipeline. One intertie (PRV station) can supply water to the Valley 196 Zone from the Seattle Bow Lake transmission pipeline. Currently there are ten reservoirs in the system, strategically located to provide adequate equalizing and fire flow reserves for all pressure zones. PRVs are used to supply lower pressure zones from higher pressure zones that contain water storage reservoirs.

A description of each facility and any major changes are summarized in the following sections. 2.2.1 Source of Supply The City has nine supply sources that supply water from three aquifers and one artesian spring. Each of the supply sources are described in detail below, including development and improvements to each source. Table 2.2 lists the active supply sources and the rater{ capacity of each. The table does not include the inactive source, Well 4, or the Seattle interties_ 2.2.1.1 Sorinabrook Sorinas (DOH Source S05 Located at the south end of the City, Springbrook Springs (Spring) is an artesian spring and was first used in 1909. The infiltration gallery was upgraded and a sanitary seal was added in 1976 (project number W-0422). Chlorination was added in 1976 (W-0423). The chlorination building is located approximately 300 yards from the infiltration gallery and is adjacent to the transmission main. Fluoridation was added in 1986 (W-0851) via an addition to the chlorination building. Corrosion control treatment to comply with the Lead & Copper Rule (pH adjustment with sodium hydroxide) was added in 1999 (W-2238)_ A sodium hydroxide storage building was added as part of this project. The City has acquired ownership of a significant amount of property to form a watershed directly surrounding the Spring. A chain link fence has been erected around the property to restrict access to and activities within the watershed_ The last segment of chain link fence was installed in 2002 (W-2980). The Spring provides direct service to the Valley 196 Zone. In June of 2010, a motorized valve was added to the treatment facility to stop the flow of water when the chlorine residual drops below a safe level. The power source is a 20 -kW generator (propane fuel source). The generator is auto -start and the transfer from commercial power to electric generator power is automatic. Currently, flow control is via a manually set gate valve (throttling valve).

Well PW -3 was originally drilled in 1959 and the wellhead constructed in 1962 (W-0119) and was replaced by Well RW -3 (DOH Source S03) (W-0880) which is co -located with RW -1 and RW -2 in a wellhouse in Liberty Park adjacent to Houser Way N and the Cedar River. The water right for PW -3 was transferred to RW -3. Project W-0880 included chlorination and fluoridation. Corrosion control treatment to comply with the Lead & Copper Rule (pH adjustment with sodium hydroxide) was added in 1999 (W-2238). A manual transfer switch with Kirk -Key safety system was added in 1999 to allow the wellhouse to be powered by a City -owned portable generator (W-2784). In 2007, an emergency electrical power generation facility was constructed at the Mt. Olivet Reservoir and BPS site to provide backup power for the Mt. Olivet BPS and Wells RW -1, RW -2, and RW -3 (W-3239). A power transmission line was installed from the new power facility to an automatic transfer switch located at the transformer adjacent to the wellhouse.

The portable generator and manual transfer switch configuration remains as a secondary backup. The automatic transfer switch, which was originally installed in 1988 (W-0880), was rebuilt in 2010. Primary disinfection with continuous chlorine concentration monitoring — using a loop of large diameter pipe in Liberty Park — was added to the three wells in 2003 (W-2893). Each well is individually metered and is controlled by the elevation in the North Talbot Reservoir. Additionally, in 2010 the backpressure control valves were converted to flow control valves to prevent the flow rate from exceeding the water right Qi. The meters are located inside the wellhouse. The wells are pumped into the Valley 196 Zone. 2.2.1.3 Well 8 MOH Source S071 Well PW -8 was drilled in 1968 and the wellhead constructed in 1969 (W-0310). The facility is located in Cedar River Park adjacent to Interstate 405. Project W-0310 included chlorination. Fluoridation was added in 1986 (W-0851). Corrosion control treatment to comply with the Lead and Copper Rule (pH adjustment with sodium hydroxide) was added in 1999 (W-2238). The electrical system was rehabilitated in 1990 (W-1020). The rehab included an automatic transfer switch and stubbing out a 4 -inch electrical conduit from the main panel to the west side of the building for a future emergency power feed (refer to WTR-13-0035, Emergency Power System Study, 1989). This is a metered source and is controlled by the elevation in the North Talbot Reservoir. The meter is located in a vault adjacent to the wellhouse. The well is pumped into the Valley 196 Zone 2.2.1.4 Well 9 (DOH Source S091 Well PW -9 was drilled in 1984 (W-0665) and the wellhead constructed in 1985 (W-0718). It is located in Cedar River Park near where 1-405 crosses State Route 169 (SR -169). Project W-0718 included chlorination and stubbing out a 3'/ -inch electrical conduit from the main panel to the west side of the building for a future emergency power feed (refer to WTR-13- 0035, Emergency Power System Study 1989). Fluoridation was added in 1986 (W-0851). Corrosion control treatment to comply with the Lead & Copper Rule (pH adjustment with sodium hydroxide) was added in 1999 (W-2238). This is a metered source and is controlled by the elevation in the North Talbot Reservoir. The meter is located in a vault adjacent to the wellhouse.

The well is located on the northwest corner of Jones Avenue NE and NE 24th Street. PW -5A replaced PW -5 (formerly Kennydale Well No. 1), which had severe sanding problems and could not be successfully redeveloped. The original PW -5 was drilled in 1953_ Project W-0888 included chlorination and fluoridation as well as switchgear and a receptacle to feed power from a portable generator set. Treatment for corrosion control is not necessary, as the pH of the raw water is about 8.0. This source can be used for summer peaking supply but has taste and odor problems. The raw water, like that of the Maplewood wellfield, contains hydrogen sulfide, iron, manganese, and ammonia. At some time in the future, additional treatment will be added to address these problems_ This is a metered source and is controlled by the elevation of the Highlands 435 Reservoirs. The meter is located in a vault 45 feet to the east of the wellhouse. The well is pumped into the Highlands 435 Zone. 2.2.1.7 Maplewood Wellfield DOH Source S13 Located at the Maplewood Golf Course on Maple Valley Highway, the Maplewood Wellfield consists of three wells: PW -11 (DOH Source S11), PW -12 (DOH Source S15), and PW -17 (DOH Source S12)_ PW -11 and PW -17 were drilled in 1989 (CAG -88-030) and the wellheads constructed in 1991 (W-0850 and W-1027). PW -12 was drilled in 1994 (WTR-13- 042) and the wellhead constructed in 1998 (W-2279). Treatment for the water from these wells is provided at the Maplewood Treatment and Booster Pump Station Facility, which was constructed in 1995 (W-1052). The raw water contains hydrogen sulfide, ammonia, manganese, and a small amount of iron. The original strategy for treating the water was to remove hydrogen sulfide using aeration and to keep the manganese in solution using ortho- polyphosphate (sequestering) as well as chlorinating and fluoridating the water. Treatment for corrosion control is not necessary, as the pH of the raw water is about 8.0. The presence of ammonia was discovered after the plant went online. The sequestering did not work and the water utility received numerous complaints regarding staining, taste, and odor. The method used for secondary disinfection was changed from chlorination to chloramination, which limited the areas in which the water could be used in the distribution system due to problems with mixing the Maplewood water with the water from the other sources. In January 2002, the City shut the wellfield down and began design and construction efforts to replace the treatment. A treatment pilot plant study had been conducted in June and July of 2001. The resulting design consists of: Converting hydrogen sulfide to sulfate by adding oxygen from air and reacting on granular activated carbon filters.

Converting ammonia to nitrogen gas by adding chlorine and reacting in a contact basin_ Construction (W-2953) of a new treatment building began in October 2003 and the treatment plant was put into operation in September 2006. The project included changing the method of chlorination from chlorine gas to sodium hypochlorite liquid_ Fluoridation is accomplished by using the existing plant. The project also included a manual switchgear with Kirk -Key safety system to allow powering one 1,500 -gallon -per -minute (gpm) well, one 1,500-gpm low -lift pump, and one 1,500-gpm high - lift pump and associated treatment equipment with a City -owned portable generator. Each well is individually metered. The meters are located in the new treatment building. Flow from each well is kept below the proposed Qi water right by using flow control valves. The wells are controlled by either the elevation in the Highlands 565 Reservoir or the Rolling Hills 590 and 490 Reservoirs (see discussion of Rolling Hills Booster Pump Station — in particular the back -pressure sustaining valves regulating the flow between the 490 and 590 pressure zones). The treated water is pumped to the clearwell located at the existing Maplewood Treatment 1 Booster Pump Station facility. From the clearwell, the water is pumped to either the Highlands 565 Zone or the Rolling Hills 594 Zone. The City continues to gather data on the operation of the wellfield for the purpose of developing an operational strategy and operations plan. 2.2.1.8 Well 4 (DOH Source S06) Well 4 was drilled in 1942 for the Northwest Water Company. The well was removed in 1962_ The City has an active water right of 170 gpm for the well (GWC 884-D). 2.2.1.9 Seattle Interties DOH Source S08 Currently there are ten interties with SPU. Two of the interties are used to supply water to the Boeing Renton Plant via two 10 -inch mains. Prior to 2001, Seattle sold this water directly to Boeing. In 2001, in accordance with a revised franchise agreement between Seattle and Renton, the metering points for the two 10 -inch service lines were moved closer to the SPU Cedar River Pipelines (W-2890), the source, and Renton began purchasing the water wholesale from Seattle and selling the water to Boeing. One of the ten interties was originally constructed as a retail supply point for Seattle to provide water to the Longacres Racetrack site. In 1994, the connection was upgraded (W- 2071) and is currently used as a backup fire flow supply for the Boeing Longacres site. This is an 8 -inch connection to the 60 -inch SPU Bow Lake transmission main at PRV Station 24. This intertie was modified in 2010 (W-3553) with a flow control valve so that it can be used to provide wholesale water to the Renton system in the future. February 14, 2012 - DRAFT 2-8 pw:llCarollolDocumenlWCIienilWNRenionf8595AOCIDeiiverables!Chapter 21Ch02.docx One of the interties is configured for supplying water to the SPU Mercer Island Pipeline.

Storage is provided by reservoirs and elevated tanks located within the distribution system. The City currently operates ten distribution system storage facilities and an operational storage/equalizing/detention reservoir at the Maplewood Treatment Plant. This section provides a description of the function and condition of each of these facilities. Currently two of the reservoirs have flow meters — Highlands 565 and Hazen Reservoirs. Table 2.4 lists all of the City's existing storage facilities and summarizes the physical characteristics. The recommended sizing and location of future storage facilities are presented in Chapter 9, Capital Improvement Program. 2.2.2.1 North Talbot Reservoir (Valley 196 Zone) Located at Talbot Hill Park near the intersection of Talbot Road S and S 19th Street, this 5 - million -gallon (MG), cast -in-place, reinforced concrete underground reservoir was constructed in 1976 (W-0419). The reservoir replaced two uncovered 0.5 -MG reservoirs that occupied the same site. In 1989, CH2M Hill visually inspected the reservoir and noted the following: The joint sealant was in good condition. Leaching of the concrete was observed. The leaching of the columns was slightly greater than observed on comparable structures. February 14, 2012 - DRAFT 2-10 pw:!lCarolWDocument&lClienUWAlRenten1B595A00/Deliverables/Chapter M02.dacx CH2M Hill made the following recommendations.- Drain ecommendations: Drain and inspect the reservoir every two to five years. Replace the ladder and overflow pipe supports with stainless steel. Install galvanic cathodic protection anodes to protect metal associated with the intake piping, wash -down piping, and other metals submerged in the reservoir. The interior was visually inspected again in 2010 by Water Utility staff who noted that all steel and iron surfaces were badly corroded, including the access ladder; inlet/outlet pipe and 2.5 -inch wash down pipes, which are no longer usable. The floor slab appeared to be in good shape with no exposed rebar and minor pitting near the columns. The columns appeared to be in fair condition with some areas of exposed aggregate and rust staining. The origin of the rust staining was not determined_ The roof to column connections appeared to be in good condition. The exterior of the reservoir roof is a tennis court. It has been noted that several large and small "bird baths" exist on the roof and retain rain water during storm events. 2.2.2.2 Mount Olivet Reservoir (Valley 196 Zone) Located near the intersection of NE 3rd Street and Bronson Way NE, this 3 -MG above- ground welded steel tank was constructed in 1954 (W-1141). CH2M Hill has periodically inspected it over the years (1969, 1977, 1982, 1985, 1989, and 1997). In 1971, an impressed current cathodic protection system was installed (W-0371). The exterior was recoated in 1978 (W-0476). The interior was recoated in 1991 (W-1035). The exterior was recoated and the cathodic protection system replaced in 1999 (W-2787). The exterior was recoated again in 2008 (W-3449) because of the failure of the 1999 coating. The interior was inspected most recently in 2010. The steel stringers between the roof beams are corroded badly and need to be replaced. In 2009, the City performed a preliminary design (WTR-13-0104, Water Distribution Storage Planning Study), which estimated the cost of replacing the reservoir at $8.25 million for a 6.9 -MG reservoir. This project is included in the City's water Capital Improvements Plan (Chapter 9). 2.2.2.3 Highlands 435 Reservoir—1.5-MG Hi hlands 435 Zone Located at the Highlands Reservoir site east of the intersection of NE 12th Street and Monroe Avenue NE, this reservoir was originally constructed as an uncovered reservoir during World War II (circa 1942). The reservoir was concrete -lined, rectangular in shape, partially in -ground and partially above ground with bermed excavated material. In 1966, the reservoir was covered (W-0098). In 1986, the beams for the cover were sand blasted and painted. In 1987, the roof beams were inspected for cracks; none were found (W-0909). In 2000, CH2M Hill inspected the reservoir for leaks and a preliminary design was conducted to increase the inflow and outflow piping (WTR-13-0072). The inspection was prompted by a concern that the Highlands 1.5 -MG and 2 -MG reservoirs had been damaged February 14, 2012 - DRAFT 2-11 pw 1/Carollo@mumentslClientPNNRentonlB595A00IOOiverahleslChapter 2lCh02.docx in the January 28 1995, Robinson Point earthquake (5.0 magnitude) as evidenced by wet ground around the chlorination booster station building (further examination discovered the problem was a leaking service line). Because of the concern that the two Highlands 435 Zone Reservoirs will suffer major damage in a large earthquake, the City plans to replace them in the future. In 2009, the City performed a preliminary design (WTR-13-0104, Water Distribution Storage Planning Study), which estimated the cost of replacing both of the Highlands 435 Zone Reservoirs (1.5 MG and 2.0 MG) at $21.3 million for a 15.2 -MG, two- compartment reservoir built in two phases. This project is included in the City's water Capital Improvements Plan (Chapter 9). 2.2.2.4 Highlands 435 Reservoir— 2 -MG (Highlands„435 Zone) Also located at the Highlands reservoir site, this covered, concrete lined, partially in -ground, partially aboveground reservoir was constructed in 1960 (W-0024)_ In 1986, the beams for the cover were sand blasted and painted. in 1987, the roof beams were inspected for cracks; some were found at the column locations (W-0949). In 1992, reinforcing collars were installed at the roof beam -column intersections and various cracks and joints in the concrete liner were sealed (W-1 081). See discussion above for the 2000 inspection. See discussion of reservoir replacement above. Replacement of this reservoir is also included in the City's water Capital Improvements Plan (Chapter 9)_ 2.2.2.5 Highlands 565 Reservoir - 0.75 -MG (Highlands 565 Zone) Also located at the Highlands reservoir site, this 0.75 -MG elevated steel reservoir was constructed in 1960 (W-0018). CH2M Hill has periodically inspected it over the years (1969, 1973, 1977, 1985 1989, and 1998) as part of an evaluation of all reservoirs, and again in 2009 with water utility staff. In 2010, LiquiVision Technology performed a dive inspection of the interior surfaces. In 1971, an impressed -current cathodic protection system was installed (W-0371). The exterior was recoated in 1978 (W-0476). In 1996, Chicago Bridge & Iron inspected the reservoir. In 1997, the interior of the reservoir was recoated, the impressed cathodic protection system was replaced, and additional railing and a safety climb rail were added (W-2210). Also, in 1997 the exterior of the reservoir was recoated (W -2303) - During the Nisqually earthquake of February 28 2001, (6.8 magnitude) the cross bracing of the tower structure was plastically deformed. In 2003, the bracing was repaired and the tank structure seismically rehabilitated (W-3005). The rehabilitation consisted of installing friction dampeners on the cross bracing and flexible connections where the water mains interface with the tanks. In 2049, a two-way flow meter was added to the single inlet 1 outlet pipe that connects the reservoir to the distribution system (W-3214). The exterior of the reservoir is due to be recoated during the time period 2011 — 2014. Replacement of this reservoir is included in the City's water Capital Improvements Plan (Chapter 9).

The Windsor Hills BPS was taken out of service in 2010. It had been a backup to the Mt Olivet and Houser Way BPS. A description of each of the facilities is included in the following discussion. Table 2.5 provides a summary of each of the pump stations and the rated capacity of each pump. 2.2.3.1 Mt. Olivet Booster Pump Station Located adjacent to the Mount Olivet Reservoir, the Mt Olivet BPS pumps from the Valley 196 Zone to the Highlands 435 Zone. The BPS was constructed in 1967 (W-0262). In 1989, one booster pump was added and the electrical, heating, and ventilation systems were rehabilitated (W-0931). In 2007, an emergency electrical power generation facility was constructed at the Mt Olivet reservoir and BPS site to provide backup power for the Mt Olivet BPS and wells RW -1, RW -2, and RW -3 (W-3239). This BPS now has emergency backup electrical power with auto -start of the generator and auto -transfer from commercial to backup power. Flow from the station is measured by one meter located in a vault outside the station. The pumps are controlled by the elevations of the Highlands 435 Zone reservoirs. Replacement of this BPS is planned with replacement of the Mt. Olivet Reservoir. This project is included in the City's water CIP (Chapter 9). 2.2.3.2 Houser Way Booster Puma Station Located on the northwest corner of the intersection of Houser Way N and N Marion Street, the Houser Way BPS pumps from the Highlands 196 pressure zone to the Highlands 435 and Kennydale 320 pressure zones. The BPS was constructed in 1996 (W-2089). The station has a receptacle for an emergency generator hook-up and a manual transfer switch. Meters located inside the station measure flow to the two pressure zones. The pumps are controlled by: 1. The elevations of the Highlands 435 Zone reservoirs. 2. The pressure in the Kennydale 320 Zone measured at the station.

An 8 -inch SCADA-controlled (supervisory control and data acquisition) transfer valve can allow flow from the Highlands 565 Zone to the Highlands 435 Zone. The valve is used in coordination with the Maplewood BPS when it is pumping into the Highlands 565 Zone. The BPS was constructed in 1969 (W-0324). In 1991, the station's electrical system was rehabilitated (W-1048). Flow from the station is measured by one meter located in the station. The pumps are controlled by the elevation of the Highlands 565 Reservoir. The pump station does not have emergency power back-up capability. Installing back-up power is included in the City's water Capital Improvements Plan (Chapter 9). Highlands Booster Pump Station Located at the Highlands Reservoir site, the Highlands BPS pumps from the Highlands 435 Zone to the Highlands 565 Zone. The BPS was constructed in 1960 (W-0018). In 1989, two pumps and motors were replaced and the third pump was rebuilt, the electrical system was rehabilitated (W-0924). An isolation valve was installed in 1992 (W-1023). In 2003, the wooden doors on the west side of the building were replaced with metal. This station has emergency power back-up with auto -start and auto -transfer (W-0815). Flow from the station is measured by one meter located in a vault outside the station. The pumps are controlled by the elevation in the Hazen 565 Reservoir. Replacement of this pump station is planned with the Highlands 435 Reservoirs. This project is included in the City's water Capital Improvements Plan (Chapter 9). 2.2.3.4 North Talbot Booster Pump Station Located near the intersection of SR 515 (Benson Road) and South 19th Street, the North Talbot BPS pumps from the Valley 196 Zone to the Rolling Hills 490 and Talbot Hill 350 Zones. It originally pumped to the Rolling Hills 590 Zone and Talbot Hill 350 Zone. The BPS was constructed in 1979 (W-0450). A manual transfer switch with Kirk -Key safety system was added in 1999 to allow the station to be powered by a City -owned portable generator (W-2784). In 2007, an emergency electrical power generation facility was constructed at the North Talbot Reservoir site to supply power to the North Talbot BPS (W-3239). The power is auto -start and auto -transfer. The portable generator and manual transfer switch configuration remains as a secondary backup. In 2001, a back -pressure sustaining valve was added to the station's primary discharge when a portion of the Rolling Hills 590 Zone was converted to the Rolling Hills 490 Zone as part of the Rolling Hills 3 -MG reservoir and pump station project (W-2230). The station's electrical, heating, and ventilation and control systems were rehabilitated in 2003 (W-2878).

The BPS was constructed in 1982 (W-0600)_ A manual transfer switch with Kirk -Key safety system was added in 1999 to allow the station to be powered by a City owned portable generator (W-2784). Flow from the station is measured by one meter located in the station. The domestic pumps are controlled by the elevation in the South Talbot Reservoir_ The fire flow pumps are controlled by the pressure of the 350 Zone measured at the station. Only one fire pump can operate at one time, the other pump is a back-up. The pump station does not have emergency power back-up capability. Installing back-up power is included in the City's water CIP (Chapter 9). 2.2.3.14 West Hill Booster Pump Station Located on West Perimeter Road at the Renton Municipal Airport near the control tower, this station pumps from the Valley 196 Zone to the Rolling Hills 495 Zone. The BPS was constructed in 1985 (W-0715). It has one 1,000-gpm fire pump that is driven by a diesel engine with auto -start. Flow from the station is measured by one meter located in the station. The pumps are controlled by the elevation in the West Hill Reservoir. Installing back-up power is included in the City's water CIP (Chapter 9)_ 2.2.4 Pressure Zones and Pressure -Reducing Stations The City's 15 different pressure zones provide pressures in the distribution system that range from 27 to 173 psi. The lowest service pressures occur in an isolated area at the northeast corner of Talbot Road South and Carr Road in the Valley 196 Zone. The service highest pressures occur in an isolated area in the Highlands 435 Zone near the intersection of North 4th Street and Houser Way North. The City currently serves customers within an elevation range of 11 feet to 476 feet. Table 2.6 lists each pressure zone, as it is commonly named, and the hydraulic elevation that each pressure zone provides. The hydraulic elevation is the overflow elevation of the highest reservoir in the pressure zone or the hydraulic elevation set point on the lead pressure -reducing valve. Also included in Table 2.6 are the lowest and highest ground elevations served in each pressure zone and the corresponding pressure at those elevations. February 14, 2012 - DRAFT 2-21 pw:llCarollolDocuments7OienVWAlRentonl8595Aa01aeliverables!Chapter MhOldocx Figure 2.2 shows the vertical relationship of the system's pressure zones and demonstrates how water can move up or down through the system. All pressure zones are served directly or indirectly from the City's active wells and Springbrook Springs. The downtown wells (RW -1, RW -2, RW -3, PW -8, and PW -9) directly supply the Valley 196 Zone. If the water is not consumed in the Valley 196 Zone, and it is needed in a higher zone, it is pumped by booster stations to the higher -pressure zones. Well PW -5A supplies the Highlands 435 Zone directly where it is also available for supply to the Highlands 565 Zone (through booster stations) or to the Kennydale 320 Zone via pressure reducing stations. Wells PW - 11, PW -12, and PW -1 7 supply the Highlands 565 Zone and Rolling Hills 590 Zone. It is desirable to have two or more connections (or supply points) that will allow water to move to a higher pressure zone, or downward to a lower pressure zone. This arrangement maximizes system reliability by providing multiple paths or routes that the water can take when moving between pressure zones. Although the system has 15 distinct pressure zones, not all of the pressure zones have separate storage or supply facilities. Some pressure zones are supplied exclusively by pressure reducing stations from an upper pressure zone. It is impractical to plan facilities and improvements for all of these pressure zones individually; therefore, the water system has been divided into five operating areas. Each operating area is a single pressure zone or combination of pressure zones with similar operating characteristics. For example, a lower pressure zone that is supplied exclusively by PRVs from an upper pressure zone would be combined with that upper pressure zone to form an operating area. For the majority of this plan, the pressure zones presented in Table 2.7 are included in each operating area. PRV stations are installed between pressure zones and allow water from a higher level pressure zone to flow into a lower level pressure zone at reduced pressures. The PRVs in the pressure reducing stations hydraulically vary the flow rate through the valve to maintain a constant and preset discharge pressure up to the limit of the flow capacity of the valve. The effect of a PRV on the lower pressure zone is the same as that as a reservoir whose overflow elevation is the same as the pressure setting on the valve (hydraulic elevation). Lead PRVs are located in hydraulically remote areas from both upper and lower pressure zone reservoirs to promote good circulation in both pressure zones, thus maintaining water quality. Lag PRVs may be located hydraulically closer to storage to minimize system head losses during high flow rate conditions when the lag valves need to operate.

To increase pressure and flow which would otherwise be required during an emergency such as a fire or pipeline failure. 3. To achieve optimum circulation in each pressure zone, thereby maintaining water quality_ When a PRV malfunctions in an open position and allows downstream pressures to rise above the PRV set point, damage can occur due to over pressuring of the pressure zone_ The probability of over pressuring the lower pressure zone can be greatly reduced by placing a pressure relief valve on the discharge (pressure -reduced) side of the PRV. If a pressure sensor is also installed on the PRV discharge and the pressure reading is telemetered and alarmed at the central control center, the City will know quickly when the failure is occurring and will be able to minimize damages as a result of the PRV failure. The City's PRV stations currently in operation are listed in Table 2.8.

These sources consist of one emergency well, EW -3, and several interties. All of the City's interties, regular and emergency supply, are shown in Table 2.3. The City has 10 interties as defined by RCW 90.03.383 (use prior to January 1, 1991) plus three emergency interties. Notices of the 10 interties were submitted to the Washington State Department of Ecology and Washington State Department of Health in May 1992 and then again in June 1996. Copies of all of the City's intertie and emergency supply agreements are included in Appendix D. 2.2.6 Distribution System The City's water pipelines are shown in plan view in Figure 2.1 _ Tables 2.9a, 2.9b, and 2.9c summarize the length of mains in the water system by diameter, pressure zone, material, and age.

As shown in Figure 2.1, the transmission pipelines are located primarily along the major transportation corridors. The looped 8 -inch pipelines in the well- developed residential areas of the system also provide some transmission capability. Transmission pipelines in the Valley 196 Zone predominantly run north to south, supplying the downtown business pressure zone, the Green River Valley industrial complexes, and the BPS that serve the other areas of the system. East -west pipelines that connect to the north -south transmission mains also provide additional transmission capacity. The pipe loops or grids formed by these connections help to increase system reliability and capacity throughout the system. Transmission pipelines from the Maplewood wellfield carry finished water to the Highlands and Rolling Hills Zones. Both transmission pipeline routes follow unimproved corridors and steep slopes. A high-pressure fire loop (320 -foot hydraulic grade line) encompasses a high-risk area of the industrial sector near the Paccar and Boeing plants for improved fire protection. For areas on the eastern side of the valley, the topography of the terrain dictates that the transmission corridors run in a north -south orientation within each pressure zone and in a west -east orientation between the different pressure zones_ The transmission corridor in the West Hill area runs east and west from the West Hill Pump Station to the reservoir and north and south on 84th Avenue S. A separate transmission route connects the reservoir with Skyway Water and Sewer District. Looped 8- and 6 -inch distribution mains provide a large percentage of the transmission capacity in the West Hill area. Transmission mains generally convey water between the supply sources (reservoirs or wells) to the local distribution grid where it is conveyed to the source of the demand. Ideally, minimal head losses should occur in transmission pipelines during normal demand periods, allowing these mains to also convey fire demands to the distribution system and to meet other emergencies without experiencing adverse head losses. Figure 2.1 also presents all the smaller pipelines below 12 inches in diameter that convey water from the transmission grid to the individual service connections. A distribution system functions by meeting individual demands in the immediate vicinity via branching and looping pipelines through the service area. Under normal conditions, the velocity of water in transmission and distribution mains should be less than 5 feet per second (fps) during peak demand periods, and less than 8 fps during fire demands periods_ February 14, 2012 - DRAFT 2-33 pw,liCarollolDocumentslClienYWArRenlon18595AGOIDeliverable Chapter 21Ch02.dDcx Velocities in excess of 8 fps may produce unacceptable thrust forces in underground fittings and cause excessive pipe wear or failure. Therefore, limiting velocity to less than 8 fps has been adopted by the City as a design criteria. The transmission and distribution system is comprised of water mains of four different materials: asbestos cement (AC), steel (ST), ductile iron (DI), and cast iron (CI). Current City policy is to replace all AC and ST water mains in the system as the budget permits, since transmission lines made of these materials are prone to leakage and failure. Table 2.10 summarizes the water main replacements the City has done since 2003.

The target dose is 0.8 milligrams per liter (mg/Q. Additionally, Wells RW -1, RW -2, and RW -3 are provided with primary disinfection. The water from Wells PW -11, PW -12 and PW -17 is also provided with primary disinfection as a result of the treatment process to remove the ammonia from the raw water. The City began chlorinating its drinking water in 1976. See section 2.2.1, Source of Supply for further information. The City began fluoridating its drinking water in 1986. The target dose is 1.0 mg/L. All sources, except Wells PW -8, PW -9, PW -11, PW -12, and PW -17, have the fluoride saturation and metering equipment located in the well house. Wells PW -8 and PW -9 are served by the Fluoridation Building, which is located next to Well PW -8. This building also serves a storage facility for bagged sodium fluoride. Fluoridation for Wells PW -11, PW -12, and PW -17 occurs at a central location —the Maplewood BPS and Treatment Building. Section 2.2.1 Source of Supply describes these facilities in greater detail. In 1999, the City began treating the water from the downtown wells and Springbrook Springs with sodium hydroxide to raise the pH of the water. The purpose for doing this is to make the water less corrosive and to comply with the Lead & Copper Rule. A central storage and meter facility was constructed in Cedar River Park. From this facility, diluted sodium hydroxide is fed to each of the downtown wells via HDPE pipes. Springbrook Springs has its own storage and metering system Section 2.2.1 Source of Supply provides further information regarding the treatment of water from the Maplewood Wellfield. 2.2.8 Telemetry and SCADA The telemetry and system control and data acquisition (SCADA) systems for the water system have changed over the years with the changes in technology that is available for the purpose. The following is a brief description of the current system. Certain aspects of operation and capability are not discussed for security reasons. Each site (all sources, all booster pump stations, all reservoirs, all treatment facilities, Boeing Longacres Intertie, Skyway Wholesale Meter, Dimmitt BPS, Coal Creek emergency intertie) has a remote telemetry unit (RTU) that in some cases also serves as a programmable logic controller (PLC). Information about the site is forwarded from the site to the master telemetry unit (MTU) that is located at the Water System Control Room (City Shops Administration Building). The MTU sends information and instructions back to the BTUs. Signals between the RTUs and MTU travel either by dedicated phone lines or by radio waves. At the Water System Control Room the operations staff monitor (and in some cases control) the system using a Human Machine Interface (HMI). The HMI is a PC running software that communicates with the MTU and can display information.

Projecting a realistic future water demand is necessary for planning infrastructure projects and securing adequate water supply to meet future growth. Current water requirements are documented in this chapter based on historical water use as recorded by the City. 3.1 POPULATION AND DEMOGRAPHIC TRENDS Current and projected future demographic trends were developed for the City's RWSA based on data provided in the PSRC's Population, Households, and Employment Forecast database. The PSRC Population, Households, and Employment Forecast database contains historical and future year estimates of key demographic and employment values for the Puget Sound region by forecast analysis zone (FAZ). FAZs are the geographic units used by the PSRC to report its small area forecasts of population, households, and employment. They are built up from traffic analysis zones (TAZs), with each FAZ containing between 1 to 20 TAZs. Data provided in the PSRC database is available in ten-year increments, starting with 1980 and extending through 2040. The City's RWSA and pressure zone boundaries do not coincide with the PRSC FAZ boundaries. Therefore, the City allocated the key demographic and employment variables (total households, total population, total employment) to each pressure zone within the RWSA using geographic information system (GIS) techniques. Additional data used to develop the demographic projections by pressure zone for the RWSA includes the City's list of vacant parcels within the RWSA, City zoning designations, the City's Buildable lands database, the Boeing Renton Environmental Impact Statement (EIS), and the Sunset Area Community Planned Action EIS. Appendix I contains a detailed description of the methodology used to develop the demographic projections. This section summarizes the information presented in Appendix I. 3.1.1 Historical Population and Demographics Table 3.1 summarizes the current population, as well as the number of households and employees in the RWSA, based on data from the PSRC.

Therefore, the growth capacity within the City's RWSA is limited. The majority of future growth is projected to occur within the Regional Urban Center and the Sunset Area Community Planned Action redevelopment boundaries. Therefore, the rate of growth of these redevelopment areas affects the projected build out date of the RWSA. Per City staff, the Regional Urban Center is not expected to be fully built out until the 2070 time frame. Build out of the Sunset Area is assumed to occur by 2030, based on the Sunset Area Community Planned Action EIS.

Number of connections based on records provided by City staff. Number of connections is based on end of the year numbers, except for 2010, which is based on the number of connections as of June. Based on the data provided in Table 3.3, the following is noted: Single-family Connections: Single-family connections accounted for 79 percent of connections in the RWSA in 2009. From 2004 through 2009, single-family connections increased by 1,040 connections, which is roughly nine percent. February 10, 2012 - DRAFT 3-3 pw:7lCarolb7DocumentslClientfWAlRentonlB595A001DeiiverableslCh_03 • Multi -family Connections: Multi -family connections accounted for nine percent of connections in the RWSA in 2009. From 2004 through 2009, multi -family connections increased by 22 connections, or roughly 1.4 percent. • Commercial Connections: Commercial connections accounted for seven percent of connections in the RWSA in 2009. From 2004 through 2009, commercial connections increased by 101 connections, or roughly ten percent. • Industrial Connections: Industrial connections accounted for less than one percent of connections in the RWSA in 2009. There was no growth in the number of industrial connections from 2004 through 2009. • Government Connections: Government connections accounted for less than one percent of connections in the RWSA in 2009. From 2004 through 2009, government connections increased by 12 connections, or roughly 15 percent. • Irrigation Connections: Irrigation connections accounted for roughly four percent of connections in the RWSA in 2009. From 2004 through 2009, irrigation connections increased by 99 connections, or roughly 16 percent. • Other Connections - Wholesale & Large Water Users: The City supplies wholesale water to the Skyway Water and Sewer District through one connection located in the West Hill 495 Pressure Zone. In addition, some water is purchased from SPU and sold to the Boeing Plant Area. This water is measured through two connections at the Boeing Plant. The City also provides water to the King County Wastewater Treatment Plant (WWTP) through one commercial water connection. Because the King County WWTP in considered a "large user," it has been subtracted out of the commercial connections throughout this chapter. 3.2.2 Historical Source Production The City produces water for its customers primarily through its wells and through Springbrook Springs. The City also purchases water from SPU to help serve the Boeing Plant Area. Table 3.4 lists the total water produced from 2004 through 2009 by supply source. The annual production ranged from 3,617,002 ccf in 2005 to a high of 3,959,812 ccf in 2007. The total water production in 2009 was 3,707,785 ccf. Figure 3.1 shows the average production percentage by active source for 2004 through 2009. As shown on this figure, the largest City supply sources from 2004 to 2009 were Wells RW -1, RW -2, and RW -3. These three wells accounted for 67 percent of water produced by the City during that period. Other major sources of supply in the City from 2004 through 2009 included Springbrook Springs and Well PW -8, which accounted for 16 percent and 9 percent of the total water produced during that period, respectively. The remaining 8 percent consisted of the other City wells, as well as the water purchased from SPU.

Non active sources include the Cedar River supply source Well 4, Well RW -5, and Well PW -10. 3.2.3 Historical Water Consumption by User Class Table 3.5 summarizes the total retail water consumption by customer class from 2004 through 2009. Table 3.5 also lists the other authorized water use, such as water used for construction, and the calculated unaccounted-for water from 2004 to 2009. Although the total number of City connections has increased from 2004 to 2009 (according to Table 3.3), the total retail water consumption in 2009 was slightly less than the total retail water consumption in 2004. From 2004 to 2009, the total water consumption fluctuated from 6.0 mgd in 2008 to 6.54 mgd in 2004. Water use patterns are analyzed using the amount of consumption per customer class. Figure 3.2 depicts the average percentage of each type of customer class in terms of number of accounts from 2004 to 2009, and presents the percentages of water sold by customer class from 2004 to 2009.

Commercial users account for 6 percent of all system connections and use 18 percent of all water consumed. Industrial customers account for less than one percent of system connections and two percent of water use_ While only four percent of the total number of accounts, irrigation use accounted for 13 percent of total water used. Wholesale water to Skyway, SPU water to Boeing, and water consumption at the King County WWTP site accounted for roughly eight percent of the City's consumption. Figure 3.3 presents the total water consumed by customer class from 2004 to 2009. Other authorized demands and unaccounted-for water are discussed in Sections 3.4 and 3.5. 3.2.4 Average Day, Maximum Day, and Peak Hour Demands The City's production data, which accounts for all water demand, was used to calculate the ADD and MDD for each year from 2004 to 2009 (Table 3.6). 3.2.4.1 Average Day Demand The ADD is calculated by dividing the total water produced and purchased by the number of days per year (2004 and 2008 were leap years and include 366 days per year)_ These values for the years 2004 to 2009 are presented in Table 3.6. As shown in this table, the ADD fluctuated between 7.41 mgd in 2005 to 8.12 mgd in 2008. 3.2.4.2 Maximum Day Demand Identifying the MDD is critical for establishing system supply capability, pump station discharge rates, reservoir capacity, and pump sizes. Historical values of MDD are equivalent to the highest production and purchase in one day in a given year, and are usually during the summer when irrigation is occurring. Table 3.6 presents these historical values. Similar to the ADD, the MDD from 2004 through 2009 fluctuated between 12.75 mgd in 2008 to 15.27 mgd in 2006. In order to develop future MDD projections, the historical MDD to ADD peaking factor is used. As with the MDD, the peaking factor fluctuates each year. As shown in Table 3.6, the MDD to ADD peaking factor fluctuated between 1.79 in 2008 and 1.95 in 2009. The average MDD peaking factor of 1.83 shown is used in this plan to project the future MDD. 3.2.4.3 Peak Hour Demand The Peak Hour Demand (PHD) is the highest water demand during any one-hour period of the year, and can be expressed as a multiplier applied to the ADD and/or as a multiplier applied to the MDD.

The diurnal patterns, when applied to the MDD, yield a PHD for each operational area. More information related to the development of the operational area diurnal patterns and the PHD to MDD peaking factors is provided in Chapter 7. 3.2.5 Seasonal Variation in Consumption by Customer Class In order to better assess the City's water use, an analysis was also performed on seasonal water use. Figure 3.4 depicts the variation in historical average monthly water consumption from 2004 to 2009_ Figure 3.5 shows the variation of water use for each customer class throughout the year, which is based on the average monthly water use from 2004 through 2009. Note that many of the City's customers are billed on a bimonthly basis. Therefore, the City's consumption records for these customers are based on bimonthly readings. This accounts for the fluctuations in water consumption for customer classes with consistent water consumption throughout the year, such as commercial customers, on Figure 3.5. Based on water use patterns shown in Figure 3.5, summer was defined to be May through October and winter to be November through April. The average summer and winter consumption by customer class for 2004 to 2009 is shown in Table 3.7. These values can be used to project future water demand by season. For residential customers, the winter demand value is an indicator of base indoor use, and the summer demand value shows increased seasonal outdoor use.

Total does not include unaccounted for water. 2. Average summer consumption is from May through October. Total does not include unaccounted for water. 3.3 EQUIVALENT RESIDENTIAL UNITS The demand of each customer class can be expressed in terms of ERUs for forecasting and planning purposes. One ERU is defined as the average quantity of water consumed by one average, full-time, single-family residence per day, and is calculated by dividing the average annual consumption of the single-family residential classification by the average number of single-family residential accounts for a given year. The quantity of water used by other customer classes, and by the whole system, can be expressed in terms of equivalent ERUs. The consumption per account for other customer classes is determined by dividing the average annual consumption per customer class by the number of accounts for that customer class. The ERU calculation does not include non - revenue water or distribution leakage. Table 3.8 provides the historical annual average water consumption by customer classification used to determine the ERU planning value. The historical data in Table 3.8 show an ERU water use that ranged from 164 to 176 gpd per single-family residential February 10, 2012 - DRAFT 3-14 pw.liCarollotDocarnentslClienlMlNRentoni8595AOOIDeliverableslCh_C3 account for 2004 to 2009, with an average water use of 171 gpd. This is equivalent to saying that an average family in the City of Renton uses 171 gpd. Table 3.9 summarizes the historical number of ERUs by customer class for 2004 through 2009. The number of ERUs was calculated by multiplying average number of ERUs per account from 2004 through 2009 (provided in Table 3.8) by the historical number of accounts. The number of ERUs in 2009 totaled 35,490. 3.4 OTHER AUTHORIZED CONSUMPTION In addition to service connection meters, the City tracks authorized water use for other revenue and non -revenue demands. The City's other authorized revenue consumption is mainly comprised of revenue water sold to contractors, which is measured by hydrant meters checked out to the contractor. Authorized non -revenue water use includes metered water use read on fire service detector meters. These other authorized uses are reported as "Miscellaneous" consumption in the City's billing data. 3.5 UNACCOUNTED-FOR (NATER Unaccounted-for water is defined as the difference between the total quantity of water produced/purchased from the City's supply sources and the authorized consumption. The DOH defines this water as "Distribution System Leakage." The City prefers to use the term "Unaccounted-for water" to reflect the fact that the discrepancy between water produced/purchased and authorized consumption may include losses other than those due to leakage, such as meter inaccuracy, water theft, and untracked authorized water use. By subtracting the total authorized water use from the total water produced or purchased, the unaccounted-for water is determined. The historical authorized use versus unaccounted-for water for 2004 to 2009 is presented in Table 3.10 and shown on Figure 3.6. The data shows an average quantity of unaccounted-for water of 17.8 percent from 2004 to 2009. The previous Water System Plan calculated a lower value of 14.4 percent between 1998 and 2003. In addition, the previous Water System Plan noted a downward trend in unaccounted-for water from 1998 to 2003. The City anticipates that much of its unaccounted-for water may come from meters that are stuck or calibrated incorrectly, incorrect meter reads, and errors in the billing system. The City reports occasionally having a long delay in accounting for new water customers in their billing data. Beginning in 2011, the City plans to deploy an automated meter reading (AMR) system over a period of five years. The AMR will improve the accuracy of the comparison of production to consumption and better detect stuck meters, meter tampering and water theft.

Water used for street cleaning, pipe flushing, and reservoir maintenance are all types of authorized non -revenue water use that may not be currently tracked by the City. In accordance with Washington State requirements for systems with unaccounted-for water (or "distribution system leakage") in excess of ten percent, the City prepared a Water Loss Control Action Plan (WLCAP). According to the WLCAP, the City's current billing system was installed in 2004. Installation of the new software coincided with a significant increase from the downward trend in the calculated unaccounted-for water noted in the previous Water System Plan. An audit of the current system has not been performed. For this reason, it is not clear if the increase in unaccounted-for water is due to errors that existed in the previous billing system (that contributed to underreporting), or are now occurring with the new system. Five activities or areas of focus were identified in the WLCAP to address apparent and real distribution system losses within the City's system. These include: • Revised reporting of authorized uses. • Metering for fire training activities and estimates of water use for fire fighting. • Water audit of Renton Park's irrigation meters. • Audit of utility billing system. • Radio -read program for small customer meters. What is not known is the potential percent reduction in unaccounted-for water that could be achieved through implementation of activities associated with the five areas of focus identified in the City's WLCAP. For planning purposes, it is prudent to assume the average unaccounted-for water from 2004 to 2009 of 97.8 percent when developing future water demand projections. Ultimately, however, the City's goal is to reduce the amount of unaccounted-for water in the system to ten percent or less, as discussed in Chapter 4- 3.6 ZONING DESIGNATIONS Zoning designations and regulations provide important information in determining future water requirements. Zoning determines the area available for various types of development including both single-family and multi -family residential development, as well as commercial and other types of uses. Figure 3.7 shows the existing zoning designations for the RWSA. Zoning designations are governed by the City's Comprehensive Plan. The population, household, and employment projections developed as part of this plan were coordinated with the City's zoning designations for vacant parcels within the RWSA. The increase in the number of households and employees for each vacant parcel was February 10, 2012 - DRAFT 3-19 pw,RCaro160ocumen tsl ienVWAIRerton18595A000eliverables1Ch_03 determined using planning assumptions presented in the City's Buildable Lands Database according to the parcel's zoning designation. The total increase in households and employees was then summarized by pressure zone to calculate the "growth cap" for each pressure zone (i.e., the total number of households or employees than can be accommodated in each pressure zone). The projected PSRC growth rates were then applied to each pressure zone for households, employees, and population to determine the year in which each pressure zone is projected to build out (i.e., when the PSRC growth projection reaches the calculated growth cap). The Regional Urban Center and Sunset Planned Action area were considered separately based on information presented in their respective EISs. 3.7 PROJECTED NUMBER OF CONNECTIONS Future demand is directly related to projected growth in the RWSA. Growth projections for population, households, and employment were developed by pressure zone as summarized in Section 3.1.2. The population, household, and employment projections were converted into percentage growth rates for each pressure zone relative to the 2010 population, household, and employment values developed by the PSRC. Detailed tables with the overall growth rate in population, households, and employment by year for each pressure zone are included in Appendix I. The future number of connections per pressure zone were determined by multiplying the accounts in 2010 by the derived growth rates per zone. Residential accounts were multiplied by the total household growth rates. Commercial, industrial, and irrigation accounts were multiplied by the employment growth rates. The government accounts were projected using the total population growth rates. Table 3.11 summarizes the projected average annual growth rates by customer type through 2071.

Identification of system improvements such as supply, pumping, storage, and piping requirements are all related to demand projections. Future water system demands are based on projected ERUs, which in turn are based on the projected number of accounts discussed earlier in Section 3.7. This section summarizes February 10, 2012 - DRAFT 3-22 pw:ll CarallaDocumentslClientlWNRenlon7B595AOCIWiiuerableslCh_03 the ERU, ADD, and MDD projections, as well as the potential range in future demands associated with various factors, such as variations in ERU values, unaccounted-for water, climate change, and water conservation. 3.8.1 Projected Equivalent Residential Units The projected number of ERUs for the RWSA was calculated by multiplying the projected number of accounts provided in Table 3.12 by the number of ERUs per account provided in Table 3.8. The total number of ERUs for each customer type for the selected planning years is presented in Table 3.13. Figure 3.8 provides a visual representation of the projected ERU growth rate. It should be noted that the projected ERUs do not include distribution leakage, miscellaneous water use, or wholesale customer demand. These additional demands are included in the projected demands, as described in Section 3.8.2.

The service connection demands are added to the distribution leakage, miscellaneous water use, and wholesale water to project the total average day demand (Table 3.14), as described below: Wholesale and Large Water Users: The City has three customers that are considered large water users, consuming an average of roughly 100,000 gpd or more. These are the Boeing Plant, the King County WWTP, and the City's wholesale customer, Skyway. Wholesale Water to Skyway: Wholesale demands for Skyway are taken from the Skyway Water and Sewer District Comprehensive Plan - Water and Sewer Systems. Forecast demands were only available through 2022. Skyway wholesale water demands from 2031 through 2071 are assumed to be equal to the 2022 demands. King County WWTP and Boeing Plant: For the purposes of the future water demand projections, it was assumed that the King County WWTP and the Boeing Plant's water demand would not increase in the future. Based on consumption data provided by the City for these two users, there was a downward trend in water demand from these customers from 2004 to 2009. As previously noted, the Skyway Wholesale demands were projected from information presented in the Skyway Comprehensive Plan. Other Authorized Water Consumption: Other authorized water consumption fluctuated between 0.38 and 0.88 percent of the total City production between 2004 to 2009, with an average of 0.57 percent. The demand projections in Table 3.14 assume that other authorized water consumption will account for 0.57 percent of total City demand through 2071. However, tracking of this demand is anticipated to grow as the City improves tracking of other authorized uses - Unaccounted -for Water: Distribution system leakage fluctuated between 15.8 percent and 20.2 percent of the total City production between 2004 and 2009, with an average of 17.8 percent. The demand projections in Table 3.14 assume that unaccounted-for water will continue to account for roughly 17.8 percent of the total City demand through year 2071. Chapter 4 includes a discussion of the actions to be taken by the City to help meet the ten percent goal. The projected MDD is simply the projected ADD multiplied by the MDDIADD factor of 1.83. The projected IMDD for the Skyway Wholesale demand was based on the projections provided from the 2005 Skyway Comprehensive Plan. Table 3.14 summarizes the projected MDD_ Figure 3.9 provides a visual representation of the projected system -wide ADD and MDD. Average day and maximum day demand projections by pressure zone are included in Appendix I.

Recognizing that certain assumptions built into the demand projections presented in Section 3.1.12 will vary in the future, the projected water demands were bracketed to provide a range in demands that may be experienced in the future. The variables considered in the development of the range in demand projections include: Removing the Build -Out Cap: As described in Appendix 1, a development "cap" was applied to build -out conditions, which assumes that no redevelopment occurs beyond the two specific redevelopment areas identified by the City. A high growth scenario was evaluated to allow growth to continue beyond this cap, following the PSRC growth projections and assuming linear growth continues beyond 2040. This scenario therefore assumes additional redevelopment. Variation in Water Use per ERU: From 2004 to 2009, the historical water use per single-family residential connection (Le., the ERU) varied between 164 gpd and 178 gpd. To account for this variability, the low end and high-end water demand projections assume an average water use per ERU of 164 gpd and 178 gpd, respectively. Unaccounted-for Water: Unaccounted-for water varied between 15.8 percent and 20.2 percent of the total City production between 2004 and 2009. Additionally, the City could potentially reduce the amount of unaccounted-for water within the system in the future by addressing the five areas of focus listed in Section 3.5. The goal of the State of Washington's Water Use Efficiency Rule is 10 percent. For this reason, the low-end water demand projections assume an unaccounted-for water of 10 percent. The high-end water demand projections assume the historical average of 17.8 percent. Other Authorized Water Consumption: From 2004 through 2009, other authorized water consumption varied between 0.38 and 0.88 percent of the total water producedlpurchased by the City. For this reason, the low-end water demand projections assume that miscellaneous water consumption will account for 0.38 percent of the total demand, and the high-end demand projections assume that miscellaneous water consumption will account for 0.57 percent (historical average) of the total demand. Climate Change: The impacts of climate change could potentially impact the City's projected water demand. In 2009, the Water Supply Forum, which is a voluntary organization comprised of representatives from King, Pierce, and Snohomish counties, released its 2009 Regional Water Supply Outlook. This document serves as a comprehensive assessment of municipal water supply and demand in King, Pierce, and Snohomish Counties. Chapter 3 of the Regional Water Supply Outlook provides a narrative of the effect of climate change in Puget Sound Region. February 10, 2012 - DRAFT 3-28 pw:ll CarollolDocuments'CllenVVVAlRenton!&595ACOIDelnrerableslCh_03 In general, the Regional Supply Outlook asserts that climate change will likely lead to increased irrigation with an extended growing season and lead to increasing temperatures, seasonal shifts in precipitation, more evaporation, and increased frequency of drought events. Chapter 7 of the Regional Supply Outlook provided water demand forecasts for the area, which include the potential effects of climate change. Based on the information presented in this chapter, it is estimated that climate change could lead to an average increase in water demand of roughly 6 percent by year 2060. For the purposes of this study, it was assumed that the effect of climate change on the projected water demands would increase linearly to 6 percent through 2030, and remain constant at 6 percent through 2071. Based on the assumptions listed above, a potential range of future water demands was developed as shown on Figure 3.10 and summarized in Table 3.16. The range in demands is bracketed for both high end and low-end projections with and without the effect of climate change. As shown in Table 3.15, the projected 2071 ADD could range between 11.3 mgd and 13.8 mgd without climate change. Considering the effect of climate change, the 2071 ADD could range between 11.3 mgd and 15.1 mgd_ The projected 2071 MDD could range between 21.0 mgd and 27.9 mgd without the effect of climate change, and 22.2 mgd to 29.6 mgd considering the effect of climate change. The "base" demand projections shown on Figure 3.10 and summarized in Table 3.15 are identical to the demand projections summarized in Section 3.8.2, and assume the average water use per ERU, unaccounted- for water, and other authorized water use from 2004 through 2009. It should be noted that the potential range in future demands shown on Figure 3.10 does not account for demand reductions associated with additional conservation measures by the City. These demands are introduced in Section 3.8.4 and summarized in Chapter 4. 3.8.4 Projected Range of Demands with Additional Conservation The City has developed goals related to its WUE program. Implementation of the measures identified by the City could lead to reductions in the City's projected water demands in the future. More detailed information regarding the City's WUE program, as well as the established goals of the program, is included in Chapter 4. Water demand projections considering the effect of water conservation are also included in Chapter 4.

During this period, the City will join the Saving Water Partnership, which will expand the breadth and depth of the City's conservation activities. In 2003, the Washington State Legislature passed the Engrossed Second Substitute House Bill 1338, known as the Municipal Water Law or the Water Use Efficiency (WUE) rule, to address the increasing demand on Washington's water resources. This law established that all municipal water suppliers (MWS) must use water more efficiently in exchange for water right certainty and flexibility to help them meet future demand. The WUE program, which became effective on January 22, 2007, emphasizes the importance of measuring water use and evaluating the effectiveness of the water supplier's WUE program. The intent is to minimize water withdrawals and water use by implementing water saving activities and adopting policies, resolutions, ordinances, or bylaws. This chapter follows the guidelines set forth in the Water Use Efficiency Guide Book, Third Edition, January, 2011 as well as the Water System Planning Handbook (April 1997). The WUE Guide replaces the Conservation Planning Requirements, March 1994. The following four fundamental elements in the WUE program are discussed in detail below: Planning requirements. 2. Distribution leakage standard. 3. Metering requirements. 4. Conservation planning and goal setting. 4.1 PLANNING REQUIREMENTS A municipal water system plan is required to include the following WUE elements: Data collection. Demand forecast. 4.1.1 Data Collection The WUE rule requires the collection of production and consumption data on a regular basis. These are utilized in this planning document to forecast future demand, describe water supply characteristics, to aid in water management decision making, to calculate distribution system leakage (DSL), evaluate the WUE program, and be submitted to the state in the annual WUE report. Data is summarized as monthly and annual totals for both February 10, 2012 - DRAFT 4-1 pw:fiCarollolDocumenWCAienVVVAVRenton18595Aa01Deliverables/Chapter 41ChUdacx production and consumption, Table 4.1 details the types of water production and consumption data collected. Table 4.1 Categories of Data Collection Water Volume Entering Distribution System Water Produced (from Renton wells and spring) Water Purchased (from City of Seattle) Authorized Water Consumption - Metered Single-family and Single-family Irrigation Multi -family and Multi -family Irrigation Industrial/Commercial/institutional Industrial/Commercial/institutional Irrigation Combined Class Irrigation Renton Maintenance Use Agriculture Interties Wholesale Authorized Water Consumption - Non -metered Fire Fighting Tank/Reservoir Cleaning 4.1.2 Demand Forecast Demand forecasting identifies how much water will be needed in the future. The demand forecast projects demand with and without savings obtained from the WUE program conservation measures. The forecast assumes an average annual reduction in water use by 0.5 percent per connection and per employee per year through 2020. The forecasted demands were developed using demographic projections from the PSRC and the City's Planning Department including housing and population forecasts, as well as land use plans. The details of the demand forecast for the Plan can be found in Chapter 3, Planning Data and Water Demand Forecasts. 4.2 DISTRIBUTION SYSTEM LEAKAGE Municipal water suppliers must now meet a 10 percent or less DSI- to comply with the WUE standard. Leakage is to be presented both as a percentage and as leakage volume, and based on a rolling three-year average. Renton collects system production and consumption data using its source, intertie, purchase, and service water meters. Data is summarized as monthly and annual totals for both production and consumption. February 10, 2012 - DRAFT 4-2 pw:!ICarollcdDocumenWQient7WAlRentcn18595AOOfDeliverables/Chapter 4fCh64.docx The WUE requirements establish a 10 percent or less DSL standard based on a 3 -year rolling average. Table 4.2 utilizes collected data to determine distribution system leakage for the data period 1988 to 2010_ Annual DSL is calculated in both percentage and volume. The graph of the rolling 3 -year average, Figure 4.1, shows that the DSL is on a downward trend. Because Renton's DSL exceeds 10 percent, a "Water Loss Control Action Plan" was developed. Implementation began in 2008. The Plan can be found in Appendix P_ Implementation of this plan establishes compliance with the WUE rule.

Renton also provides service metering for its customers_ Customer consumption meters are categorized either as large (3 -inches or greater) or small (smaller than 3 -inches). Renton is in full compliance with the WUE metering requirements. All large service meters are tested annually and repaired as needed. Small service meters are repaired or replaced on an as -needed basis. Renton is in the process of implementation of an AMR program. One benefit of the AMR program will be to provide more time for operations and maintenance staff to perform maintenance on small, as well as large meters, on a more regular schedule. This should contribute to lowering of DSL. 4.4 CONSERVATION PLANNING Fundamental to developing a successful WUE and Conservation Plan, is an understanding of how, where and when water is used. This knowledge helps to see where savings and efficiencies could be made. Renton has a total of 17, 395 connections (2010), dominated by domestic connections as shown in Table 4.3. Likewise, Figure 4.2 indicates that domestic single- and multi -family consumption is the dominate use. Despite the fact that the combined domestic use of single and multi -family connections consumes the greatest percentage of water produced, the Commercial and Industrial sector with only 6.8 percent of connections, accounts for 25 percent of overall consumption. Both of these sectors have potential efficiency and conservation savings. Table 4.3 Connections by Customer Category — 2410 Single- Multi-familyCommercial Government Irrigation Total family & Industrial & Schools 13,257 1,551 1,185 693 709 17,395 76.2% 8.9% 6.8% 4.0%4.1% 100% Monthly consumption is presented in Figure 4.3. Summer irrigation season generally begins in May and extends through September_ The peak irrigation months of July and August 2010, experienced a 63 percent increase in average daily water consumption; this is typical. This shows that the irrigation and general outdoor summer use also have potential efficiency and conservation savings.

In 1989, the initiation of a leak detection and repair program resulted in a noticeable drop in volume of unaccounted-for water. Since 1990, conservation programming has included, school outreach, a speakers' bureau, fairs and promotion of regional programs. The addition of the 12 -month water consumption history on water bills was started in 1992. Since 1994, the City of Renton has employed increasingly complex tiered water pricing rates to encourage conservation_ Table 4.4 provides a summary of past and current conservation efforts. Those measures with an 'H' in the implementation column are historical measures and have been being implemented since before 2006. Current measures are indicated with a 'C', these have been in effect during the last six years_ Measures that will be carried forward through the next six years are indicated with a 'P'. 4.4.1.1 Consumption History The single-family residential average monthly water use per connection from 1988 through 2010 is presented in Figure 4.4. During this period, single-family consumption per connection has decreased by approximately 25 percent. Over the most recent planning period of 2004 through 2010, single-family usage has decreased by an average of 26 gpd, representing a 14 percent decrease. Overall, annual consumption per connection during this period decreased by 30 percent (Figures 5.5 and 5.6). There have been a variety of events and influences that have affected this downturn. The significant decline in water use in 1993 is in large part attributable to the drought that occurred in 1992 to 1993 and major regional education efforts. Water use following 1993 never returned to the same levels as were experienced prior to the drought_ The change in the City's rate structure (with inverted rate blocks) also occurred in 1994, and is believed to have impacted water use. In 2009, the City again instituted a more aggressive inverted rate block structure for single-family and duplex customers, as well as changes to the multi -family and irrigation rates. Overall rate increases in subsequent years have also sent a conservation message and impacted consumption_ Although, many factors contribute to the amount of water consumed, a consistent decline in water use over time is an indication that water conservation measures and education are having a long-term impact.

This rule stipulates the minimum number and type of efficiency measures that a conservation program must evaluate or implement As a municipal water supplier with more than 17,000 connections, Renton is required by the MWL to implement the five mandatory measures and either implement or evaluate the two others. These are shown in Table 4.5. It is also required to evaluate or implement nine measures of its choice. Table 4.5 WUE Mandatory Measures Must implement the following WUE measures: Status Install production (source) meters Implemented Install consumption (service) meters Implemented Perform meter calibration Implemented I ongoing Implement a water loss control action plan to Implemented / ongoing control leakage if exceeds 10% Educate customers about water efficiency at least Implemented /ongoing once per year Must evaluate or implement these WUE measures: Evaluate rates that encourage water demand Implemented efficiency Evaluate reclamation Implemented / reviewed* Renton's current conservation program was developed through a public process to support the City's WUE goals. The original objectives and goals, presented below, are being carried forward to this water system plan. It is hoped that this plan will develop the attitude and behavior of Renton residents to actively and instinctively conserve water. 4.4.2.1.1 WUE Objectives As part of the initial WUE compliance, Renton reviewed its water system and water usage and developed four objectives for its WUE plan: 1. Identify and reduce sources of distribution system leakage. 2. Ensure efficient water supply for continued growth within its service area. 3. Reduce peak day and peak season demands. 4. Continue the historical trend of reduction in customer water usage. February 10, 2012 - DRAFT 4-13 pw:llcarol€olDocumenWClienYWA/Renton18595AOOlDeliverabieslChapter 41Ch04,docn 4.4.2.1.2 WUE Goals To meet these objectives, measureable goals were defined: 1. Reduce distribution system leakage to ten percent or less by 2010. 2. Limit the peak day demand at 16.5 mgd or less through 2015. 3. Continue reduction of the average annual water use per customer connection by one- half percent per year. 4.4.2.2 Mandatory Measures Meters. Both production meters and consumption meters have been installed, with AMR underway, so those measures can be considered fully implemented. Meter calibration, the water loss control plan is ongoing and will be continued. Reclamation. A thorough evaluation of the usage potential for reclaimed water in the City was made in response to a Department of Ecology water resource policy initiative and the DDH Interim Conservation Guidelines of 1994. The study included a pilot project and long- range plan for developing a citywide distribution system that would use reclaimed water for a variety of uses. The title of the study is "City of Renton Conceptual Reuse Plan" (CDR File Code WTR-09-0009). Further, in 1995, King County, the City of Renton and the City of Seattle Water Department published a study titled "Water Reclamation and Reuse. A Feasibility Study for the King County Metropolitan Area". The study concluded that under most conditions, the present cost of reclaimed water service would be higher than the Seattle marginal cost for developing new potable supplies. A successful project would have to serve a reasonably large demand (at least one MGD) and be located adjacent to a source of secondary treated effluent_ The report noted that the King County Renton Effluent Transfer System (RETS) 96 -inch pipeline in the Duwamish Corridor already had twelve taps in place for reclamation and reuse. Therefore, site-specific reuse projects along the Duwamish Corridor were suggested as having the most potential to be cost-effective from "An Economic Analysis of the North Seattle Reclaimed Wafer Project." In 2011, the King County Wastewater Treatment Division began another engineering, environmental, and economic analysis of conceptual reclaimed water strategies. The City is working with King County to provide them with information for their study. Education. The mandatory requirement for annual customer water use efficiency education is met through the City's annual water quality report. This report includes annual consumer confidence report information, annual water use efficiency data as well as water conservation education advice. It is mailed to all households within the City's water service area. Other customer education measures are included in the selected measures below. February 10, 2012 - DRAFT 4-14 pw:llCarollolDocumenlslOienUVVNRen[on18595A001DeliverablesIChapler 4004.docx Rate Structure. The final mandatory measure, water rate structure, can be an important way of encouraging water conservation. A two-tiered inverted block rate pricing structure for single-family homes and duplexes was introduced in 1994. In 2009, Renton again evaluated and instituted changes to its rate structure. Changes included defined rates for more customer classes and also a more aggressive inverted rate block structure for single-family and duplex customers, as well as changes to the multi- family and irrigation rates. The previous and new rates for customer classes are shown in Table 4.6. Table 4.6 Changes in Customer Class Rates Previous Rate Structure New Rate Structure - 2012 (Cost per 100 cf) (Cost per 100 cf) Single-family 1 Duplex 2 -tier block rate 3 -tier block rate ($2.01 and $2.14) ($2.30, $3.09 and $3.90) Multi -family $2.01 $2.98 Non-residential $2.01 $3.16 Irrigation $2.01 $5.06 Irrigation (city accounts) $2.01 $2.27 4.4.3 Proposed Conservation Program Based on the number of connections, the WUE rule requires that, besides the mandatory measures, the City must evaluate or implement nine measures of its choice that support the proposed goals. Review of Table 4.4 shows that the City currently has nine measures beyond the mandatory ones that will be carried forward as part of the new plan. Renton's conservation strategy has historically been focused on the residential consumer, both indoor and outdoor. Continued savings attest to the success of the program. Most recently, emphasis has been on the reduction of summer peak usage and has been set as a WUE goal. The addition of the third tier and increased irrigation rates were instituted to help lower the peak consumption. 4.4.3.1 Selected Measures Water Bill Consumption History. Customer bills provide historical data to help educate customers of their usage patterns throughout the year and particularly see the impact of outdoor watering. With this information they can make informed choices related to conservation and water costs. All customers benefit from this information. School Outreach. Renton provides interactive educational experience for elementary grades through Family Science nights, Girl Scout camps and wherever requested. Targeted third grade classroom presentations will hopefully be able to be reinstated in the coming years. The City also partners with other purveyors through participation in the Partnership February 10, 2012 - DRAFT 4-15 pw:I/Carolb/DocumentslClienUWNRentcn)8595AOO1DeliverableslChapter 4004.docx for Water Conservation to produce and update educational materials to explain the groundwater story and promote conservation. Utility Bill Inserts. This avenue of communicating with the customer is a very effective means to deliver a focused message. Once or twice per year, conservation information is included with the utility bill. Messages are geared toward residential customers. Natural Yard Care Workshops. The Water Utility partners with the City's Solid Waste Department to educate customers about water efficient gardening, as well as reducing toxic chemicals in the yard and garden. Advertising and Public Outreach. Renton is a member of the regional Partnership for Water Conservation, the national Alliance for Water Efficiency, the US EPA WaterSense partnership, the Groundwater Foundation and beginning in 2012, the Saving Water Partnership. As such, the City supports their missions to promote water efficiency and conservation through local, regional, and national advertising. City Demonstration Garden. The City maintains a demonstration garden featuring low water and low maintenance plants at the 200 Mill Ave S building. The garden presents an educational viewing of well-established plants that thrive in low water and sloped conditions. WashWise Washing Machine Rebates. Since mid -2007, Renton has offered rebates to customers to replace less efficient clothes washers with ones that use less water and energy. Level of rebate depends on machine's level of water and energy savings. Through 2010, the Renton WashWise program has rebated 1,441 machines, which effects an average annual water savings of 11.2 million gallons from the use of these machines. Hose Gaskets. Replacement hose gaskets are offered at Renton River Days and other public events. Several hundred are distributed each year and continue to be popular. Savings are indeterminate but do contribute to summer peak reduction. Web Page. The Conservation web page provides information for indoor and outdoor savings as well as links to rebate and other resources. The Kids' page provides information for kids and teachers. Participation in the Saving Water Partnership will bring access to a broad set of online conservation resources to be linked through the Renton website. 4.4.3.2 Re ional Conservation Participation To help achieve the City's stated WUE objective: "Ensure efficient water supply for continued growth within its service area.", the City, as part of its long-range water supply planning, evaluated alternate sources of water supply to meet the growing water demand from the projected population growth and from development within the City's water service area. In 2010, the Water Utility evaluated alternatives for the City to obtain additional water supply from SPU, Cascade Water Alliance (CWA), and from constructing water quality improvements to currently unused Well 5A. The most cost -beneficial and reliable altemative February 10, 2012 - DRAFT 4-16 pw:IiCarolk)IDocumenlstClientlWA/RentonB595AOCIDeliverahlwChapter 4004.dou for water supply source was determined to be the purchase of water from SPU. A contract has been negotiated between the City and SPU. With this contract, Renton will become a part of the Saving Water Partnership (WSP), a consortium of water utilities that have contracts with SPU. The WSP regional partnership brings a panoply of water conservation measures and technical assistance that will be initiated in the Renton service area beginning in 2012. These new programs will extend the City's conservation program from primarily residential customers to include, owners/ managers of apartments and condos, industrial and commercial customers, and will apply to new construction and major remodels as well as existing buildings. It will also help lower summer use through peak reduction as well as overall consumption reduction. Table 4.7 presents the measures, rebates, and resources that will become part of the City's conservation program in 2012. The specific measures offered will change in 2013 with the 2013 SPU Water System Plan. New measures will reflect developing regional conservation needs.

The City manages its water system in a manner that ensures public health and safety, meets all regulatory requirements, and protects environmental resources." (Source: Renton Results — A Community Accountability Program) The policies, design criteria, and standards used in the water system plan are based on laws and policies that originate from the following sources, listed in descending order, from those with the broadest authority to those with the narrowest: • Federal Regulations - Environmental Protection Agency • State Regulations - Department of Health and Department of Ecology King County Regulations • City of Renton Ordinances - City Council • City of Renton Administrative Policies - Mayor • City of Renton Comprehensive Plan Department Policies - Public Works Department • Water System Plan Utility Policies — Utility Systems Division/ Water Utility Staff Law is set by the federal government through federal regulations, by the State of Washington in the form of statutes: Revised Codes of Washington (RCW), WAC, by King County in the form of policies, and by Renton City Council in the form of ordinances and resolutions_ City policies are established in order to provide a vision or mission of the Water Utility and to provide a framework for the planning, design, operation, management, and maintenance of the water system. City policies cannot be less stringent or in conflict with adopted laws. 5.2 SERVICE AREA, POLICIES, AND STANDARDS The City of Renton manages its water utility and water system in accordance with established federal and state regulations for public water systems. City policies and standards set forth in this chapter provide a consistent framework for the planning, design, construction, maintenance, operation, and service of the City's water system and water supply sources. The City has additional land use, development, and finance policies that February 10, 2012 - DRAFT 5-1 pw:f/Carollogacuments/ClienUWAIRenton18595Ap0IReliverables/Chapter 51Ch05.docx specify additional requirements for new development or redevelopment projects which require water service for domestic, fire protection and for other uses. The City's policies are grouped by major categories including: • Service Area. • Water Supply Planning and Management. • Water Main Extension and Service Ownership. • System Reliability and Emergency Management Plan. • Fire Protection. • Financial. • Facilities. • Organization. 5.3 SUMMARY OF POLICIES FOR WATER SYSTEM PLAN 5.3.1 Service Area 5.3.1.1 Mission Statement Ensure that Renton's drinking water supply is safe and sufficient and that the City's infrastructure is adequate to meet our community's present and future needs for water' 5.3.1.2 Service Availability The City of Renton's goal is to provide water service to all customers within the City's retail water service area in a timely and reasonable manner consistent with applicable City policies, resolutions, ordinances, the Municipal Water Law, Washington Department of Health rules and guidelines, and applicable federal, state, and local laws and plansz_ 5.3.1.3 Government Consistency Provisions of water service should be consistent with the goals, objectives, and policies of Renton Comprehensive Plan and Water System Plan. The City's Water System Plan will be consistent with local, county, and state land use authorities and plans. Water service should be consistent with the growth and development concepts directed by the City's Comprehensive Plana.

The City also has inter -local agreements with neighboring cities and water districts to address minor adjustments of service area boundaries. In general, the City's water service area is wholly located within incorporated City of Renton with the exception of several very small areas within unincorporated King County. The City uses its existing service area agreements to determine areas where water service will be provided. Therefore, annexations to the City do not affect the provisions of water service. The City's Retail Water Service area encompasses the majority of the City's Water Service Area, where the City has existing distribution mains or where distribution mains can be extended in a reasonable timeframe°. 5.3.1.5 Future Retail Water Service Area The only potential changes to the City of Renton retail water service area is for a small area near the westerly City limits, the area is shown on the service area map. This area is currently served by Seattle Public Utilities and may be served by the City in the future upon annexation. The future annexation area to be served by the City is also described in Skyway Water & Sewer District Water System Plan and in the Skyway Coordinated Water System Plan. For the purpose of the Water System Plan, the City has no intention or need to designate a Future Retail Water Service Area. 5.3.1.6 Urban Growth Area The City's urban growth area (UGA) boundary extends beyond Renton's city limits and water service area boundary. Other water purveyors serve areas outside of the City's water service area. Due in large part to the geography of the City of Renton, it is unlikely that its water service area would be extended further beyond the existing water service area. Any new areas within the City's UGA that are annexed by Renton would likely continue to be served by the other utilities currently serving them5_ 5.3.1.7 Satellite/Remote Systems The City does not allow satellitelremote systems. 5.3.1.8 Service for Annexations without Existing Municipal Water Supplies The City intends to provide water service to areas annexed to the City that do not have existing water service from other municipal water suppliers and water districts.

Areas annexed with existing municipal supply must meet the City water utility standards'. 5.3.1.10 Service for Protection of Public Health The City will allow extension of water service without annexation to areas outside of the City limits when such areas are within the City's water service area, or when no other reasonable service is available, and it is determined by the City and/or by the State Department of Health that a public health emergency exists or is imminent$. 5.3.1.11 Conditions for Service to Properties with Existina Private and or Exempt Wells The City will provide water service for domestic and for fire protection to properties within the City water service area that have existing private wells and/or exempt wells subject to the following conditions: All "exempt" wells and private wells on the property must be decommissioned in accordance to Washington State Department of Ecology (Ecology) standards and regulations, except when such wells can be used by the City of Renton for purposes including but not limited to: water supply, water supply mitigation, resource protection, environmental monitoring, or remediation of contamination. 2. All water rights, permits or certificates, for which the type of use is municipal, community, or domestic, the water rights must be deeded to the City; and any associated source(s) must either be decommissioned or deeded to the City, at the discretion of the City. Water rights, permits or certificates, for which the type of use is irrigation, industrial, or agricultural may be retained if the proposed land use is consistent with the type of use listed on the water right. If the proposed land use is not consistent with the type of use listed on the water right, then the water right must be deeded to the City; and any associated source(s) must either be decommissioned or deeded to the City, at the discretion of the City. s Source: Renton Comprehensive Plan Policy U-46, Water System Plan.

The district's or private system's facilities meet Renton's performance criteria and engineering standards, or a plan is in place to assure that they will be brought up to Renton's standards without adversely impacting Renton's existing customers financially or with regard to level of service. 3. The assumption of the district or private system is permitted by State law. 4. The City shall require that the district or private system to transfer the ownership of its water supply sources and associated water rights to the City. Water rights must be successfully transferred to the City and approved for municipal water use by the State Department of Ecology prior to commitment from the City for water service. 5.3.1.13 City Initiated Assumption of Water Districts or Private Water Systems The City will seek to assume the operation of a water district when the City Council determines that the assumption is in the best interest of the City and the assumption is consistent with the City's Comprehensive Plan. The City will follow State laws and guidelines in assuming portions of adjacent water systems as a result of annexations10 5.3.1.14 Wholesaling Water The City will continue to provide wholesale water to Skyway Water and Sewer District through a single metered connection in accordance to the current wholesale water supply agreement between the City and the District. The City is not planning to provide additional water to the District above the quantity identified in the existing wholesale agreement. The City has no plans to sell water wholesale on a long term basis to any other purveyor. Sales of water for short term basis will be evaluated in a case by case basis. 5.3.1.15 Wheeling Water The City does not currently wheel water. Water chemistry compatibility and its effects on water quality, including aesthetics such as taste and odor would be a primary consideration. The City will evaluate any request for wheeling water on a case by case basis. 9 Source: RCW, WAC, City of Renton Comprehensive Plan policy number U-49, Water System Plan. 10 Source: RCW, WAC, Council Discretion, Renton Comprehensive Plan policy number U-49, Water System Plan.

The City will work cooperatively with water suppliers and purveyors, including Seattle Public Utilities, to assure reliable water supply at the lowest environmental and economic cost. The City will pursue additional and/or new water supply and use water conservation, water use efficiency measures and water reuse programs to meet to ensure adequate water supply needs to meet the essential needs of the community and water demand created by growth targets established through the Growth Management Act (GMA) planning process. Adequate" supply is enough water to meet normal peak day demands of the City's customers. Peak day demand includes the effects of drought and curtailment. As time passes, normal demand is expected to decrease on a per household basis for two reasons. First, average household size is expected to decline, reducing the number of water users per house. Second, continued efforts to use water wisely by all customers will reduce demand. The City intends to take a cautious approach toward demand reductions that result from behavioral changes, which will not be considered permanent. Alternately, structural improvements (e.g., low -flush toilets, low -flow shower heads, or other water - saving devices) will be considered permanent reductions in demand. The City supports efficient use of water. The City supports eliminating the "waste" of water. The City has adopted rates to achieve these objectives. The quantity of water at the source shall: (1) be adequate to meet the maximum projected water demand of the retail service area as shown by calculations based on the extreme drought of record; (2) provide a reasonable surplus for anticipated growth; (3) be adequate to compensate for all losses such as silting, evaporation, seepage, etc.; and (4) be adequate to provide ample water for other legal users of the source". 5.3.2.2 Regional Water Supply Planning The City will participate in regional water supply management and planning activities. The City will monitor legislative, regulatory, litigation, and planning activities that may impact or influence the adequacy or reliability of supply12. 1' Sources: WAC 246-290-420, WAC 246-290-200, RCW 19.27.097, RCW 58.17.110, Renton Comprehensive Plan policy numbers U-36, U-42, U-54, Water System Plan. 12 Source: Council and Administration Discretion.

The City operates and monitors its water supply sources to ensure compliance with all conditions and withdrawal quantities limits for total annual withdrawal quantity and for instantaneous withdrawal quantity, established under State issued water rights certificates and permits. The City will monitor the pumping of its wells to allow aquifer recovery and to avoid impacts to in -stream flows for the Cedar River. The City has installed flow control/throttling valves and flow metering equipment system on its well pumps to monitor instantaneous pumping rates and total pumping rates. The controls are set up so that the well pumps cannot exceed their individual and total instantaneous flow rates established under the water rights certificates and permits issued by the Department of Ecology. In the demand calls for additional water, the controls are set up so that the City will receive additional water through the intertie with Seattle Public Utilities' 60 -inch Bow Lake pipeline, and if needed through two other interties with SPU at Tiffany Park and Fred Nelson pump stations13 5.3.2.4 Reclaimed Water Use The City will support the regional supplier's study of reclaimed water use opportunities and will work with King County Department of Natural Resources to identify potential reclaimed water users and demand. Any reclaimed water to be used as a source of supply should only be provided through regional water suppliers. The City has identified several potential users of reclaimed water for landscape irrigation uses, including the Boeing Longacres faCilitieS14. 5.3.2.5 Conservation and Water Use Efficiency The City will actively continue to promote voluntary conservation and the wise use of water and implement a water conservation program and measures consistent with the requirements of the Department of Health. The City will cooperate with Seattle Public Utilities to meet SPU and other regional conservation goals. The City has implemented water rate structures promoting conservation such as, residential inverted block rate and higher commodity rate for commercial and multifamily irrigation. The City is finalizing negotiations for a procurement contract for the acquisition and phased implementation of an Automatic Meter Reading (AMR) system to enhance water conservation activities and to optimize the pumping of its water supply weiisl5. 13 Source: Municipal Water Law, Water System Plan, Water Rights Certificates and Permits. 14 Source: Municipal Water Law, Water System Plan 15 Source: WAC 246-290, Water System Plan, WUE Goals February 10, 2012 - DRAFT 5-7 pw:llCamlic/DocumentslClienUWNRenlon6595AOO/DeFiverableslChapter 5045,dou The City has adopted the following Water Use Efficiency goals: • Reduce distribution system leakage and loss to 10% or less by 2010. • Limit peak day demand to 16.5 mgd or less through 2015. Continue to have 0.5% average annual reduction of water use per connection per year. 5.3.2.6 Water Shortage Response Plan The City maintains and updates a local response plan in case of a water supply shortage caused by a drought or supply interruption. The City will implement necessary water conservation measures to avoid curtailment in all but the most exceptional circumstances. The Mayor and/or City Council are empowered to declare an emergency and to carry out the necessary actions to ensure compliance with the Water Shortage Response Plan's 5.3.2.7 Emergency Interties The City has emergency interties with adjacent water systems for short-term emergency uses. The City will evaluate requests for emergency interties on a case by case basis and shall support emergency interties with adjacent systems if they benefit both providers and if they don't compromise the City's ability to serve its existing customers or its future supply needs. 5.3.2.8 Water Quality The City shall operate and manage the system to provide water quality that meets or exceeds all health requirements. The City will take steps to meet or exceed all water quality laws and standards. The City will take all reasonable measures to ensure that water reaching the point of delivery, the customer's meter, meets all water quality standards. The City shall continue to maintain and upgrade its system to provide the best water quality and service". 5.3.2.9 Cross Connection Control The City shall administer a cross connection control program that protects the City's public water supply and users of the public water supply from backflow contamination in accordance with state law and to the Department of Health regulations and guidelines. The City has an established cross connection control program and related ordinances and procedures to implement the program.

The authority to approve a latecomer's agreement is vested in the City Council. The latecomer's agreement can be granted for a period up to but not exceeding 15 years and no term extension will be granted29. 5.3.4 System Reliability and Emergency Management Plan 5.3.4.1 Service Reliability The City has built in redundancies in the operation and in the construction of capital improvements of its water system, including reservoirs, pumps, pressure reducing stations, and transmission and distribution mains, to maintain service reliability. The City has water system interties with SPU and emergency interties with neighboring water purveyors to provide water service during emergencies. All new water facilities added to the system that require electrical power shall be provided with backup emergency electrical power with automatic start and automatic transfer to and from commercial power. The power source may be an electrical generator or storage batteries. Existing facilities requiring electrical power that do not have on-site emergency electrical power with auto -start ! auto transfer shall have such capabilities added as part of the capital improvement program within the next 15 years. Emergency back-up power for sources and booster pump stations shall be capable of operating at full load without being refueled for at least 36 hours. Battery backup power for SCADA RTUs and MTUs shall be capable of providing power for at least eight hours of continuous operation without needing a recharge or replacement. Wells and booster pump stations that do not have emergency power with automatic start and automatic transfer to and from commercial power are not considered reliable, because they cannot be relied upon to provide water during a fire. If at sometime in the future installed storage is adequate to meet fire flow demands, then this policy could change. Booster pump stations shall be equipped with redundant pumps so as to meet the MDD with the largest pump serving the pressure zone out of serviceso 29 Sources: City Ordinance 4443, Renton Municipal Code 9-5- 30 Sources: WAC 246-290-420, DOH Water System Design Manual, Council Discretion, Water System Plan.

The City will provide the minimum water pressure requirement established by Department of Health at 30 psi at the service meter during maximum day demand and during peak hour demand conditions, not including a fire or emergency. The City's goal is to provide a minimum of 40 psi at the highest domestic water plumbing fixture or at the highest fire sprinkler head, except during emergency conditions. The City's goal is also to provide a maximum of 110 psi at the service meter to prevent over pressurization of water uses fixtures and appliances. Current building codes require the installation of an individual pressure reducing valves beyond the water meter where system pressures exceed 80 psi. During a failure of any part of the system, the maximum pressure shall not exceed the normal pressure rating of the pipe, generally 150 psi43. 5.3.7.2 Velocity The existing facilities will be operated and new facilities constructed to minimize damage from excessive pipeline velocities. When adding to the distribution system or replacing components of the distribution system, water mains shall be sized such that, Under normal conditions, the velocity of water in a transmission main shall be less than 4 feet per second (fps) during demand periods. Under emergency conditions, such as a fire, the velocity of water in a transmission main shall be less than 8 fps. Fire flow planning and modeling will use a de -rating procedure that limits fire flow velocities to 8 fps44. 42 Source: Council Discretion, Water System Plan. 43 Source: WAC 246-290-230, Insurance Services Organization (ISO), Council Discretion, Water System Plan February 10, 2012 - DRAFT 5-17 pw:l7Carolio/DocumentWClienUVVAIRentcn1B595A001Deliverables!Chapter 51Ch05.dou 5.3.7.3 Storage The existing storage facilities will be operated and new storage facilities constructed to comply with DOH criteria and good engineering practice. Storage within the distribution system must be of sufficient capacity to supplement transmission supply when peaking demands are greater than the source pumping capacity (equalizing storage) and still maintain sufficient storage for a fire or other emergency condition. Equalizing, fire suppression, and stand-by storage are provided in addition to operational storage. The bottom of the equalizing storage component must be located at an elevation which produces no less than 30 psi at all service connections throughout the pressure zone under peak hour demand conditions, assuming all sources are in service. Equalizing storage requirements shall be determined using the "Multiple Day Demand" method (ref: DOH Water System Design Manual, December 2009). The time period shall be five days. The analysis shall compare the cost of designing and constructing storage versus the cost of purchasing wholesale water from SPU, including the cost of upgrading and / or adding intertie connections to the SPU transmission mains. For fire flow supplied via gravity storage, the bottom of the fire suppression storage component shall be located at an elevation which produces no less than 20 psi at ground level at all points in the zone under peak hour demand condition, assuming the largest source to the zone is out of service. The fire flow storage criteria available from the ISO were considered in the study. The quantity of fire flow storage provided will approach these requirements as closely as possible, considering economic factors and other design criteria. Sufficient storage for a fire condition is the product of the fire protection water demand and the required duration as determined by the City of Renton Fire Marshall. The stand-by storage component or the fire suppression storage component, whichever volume is smaller, can be excluded from the zone's total storage requirement (also known as "nested" storage) provided that the elevation of the bottom of effective storage is no less than that elevation which produces the higher of the following criteria: 20 psi at ground level at all points in the zone under peak hour demand conditions, assuming the largest source to the zone is out of service, or 30 psi at all service connections throughout the pressure zone under peak hour demand, assuming all sources are in service. The calculation of the standby storage volume requirements shall use the "Water Systems with Multiple Sources" method (ref: DOH Water System Design Manual, December 2009). 41 Source: DOH Water System Design Manual, Fire Marshall, Insurance Services Organization (ISO), Council Discretion, Water System Plan.

This chapter also discusses the City's interties as they are related to its source of supply and provides a summary of Renton's Wellhead Protection Program. The City has pursued and developed its own independent water supply sources to meet its needs and has also been a wholesale customer of Seattle Public Utilities (SPU). In the coming years, as the limits of its water rights are encountered Renton plans to purchase more water from SPU to meet its needs. Renton will maintain its capability to supply a growing population and control water rates by: Placing additional emphasis on water conservation via customer education, incentive programs, and rates that encourage conservation. 2. Protecting the water quality of the existing wellfelds from adverse development impacts in the recharge area. 3. Continuing "beneficial use" of its well supply and protecting the legal integrity of the existing water rights. 4. Negotiating with adjacent utilities for emergency supply. 5. Participating in regional water supply organizations. 6. Considering raw water treatment as required. 7. Renewing its wholesale water supply contract with SPU. Water quality policies and programs to protect existing groundwater supply sources are among the City's highest priorities. 6.1 WATER SUPPLY RESOURCES Renton's supply is derived from five water sources: the Cedar Valley Aquifer, Springbrook Springs, the Maplewood Aquifer, the recharge area for Well 5A, and SPU supply interties. Each of these is described below and is shown on the water system map included in Appendix F, System Maps_ The SPU source of supply is described under Interties. For the City's primary supply, it maintains and operates six wells within the Cedar Valley Aquifer and three wells within the Maplewood Aquifer. It also has Springbrook Springs, a single artesian spring, and Well 5A, which is the only well that the City operates within that particular recharge area. February 13, 2012 - DRAFT 6-1 pw!lCarollolDocument JCllenUWAlRentonl8595ADOICeliverableslChapter UD06.docx 6.1.1 Cedar Valley Aquifer The primary source of the Renton municipal water supply is the Cedar Valley Aquifer, designated a sole source in 1988 by the EPA. The aquifer boundaries correspond to the aerial extent of the post-Vashon alluvium of the lower Cedar River Valley. This shallow aquifer is physically susceptible to contamination since there is no confining layer between the land surface and the water table to retard the downward migration of hazardous chemical spills or other releases of contaminants. In downtown Renton it is especially vulnerable to degradation due to the presence of numerous potential sources of contamination within the capture zone of the wellfield. In the vicinity of the wellfield constructed in downtown Renton, the aquifer consists of coarse-grained sediments deposited at the mouth of the prehistoric Cedar River during the last glacial period. The water table is approximately 23 feet from the surface and the aquifer has an average thickness of 70 feet in the vicinity of the wellfield. Soils overlying the aquifer are silt, sand, and gravel while the aquifer itself is comprised of coarser, very permeable sandy gravel. Aquifer transmissivity is estimated to range from about 1 to 2.3 million gallons per day per foot (mg/day/ft). The transmissivity of the wells RW -11, RW -2 and RW 3 is 1.00 mg/day/ft; PW -8 is 1.30 mg/day/ft; PW -9 is 2.30 mg/day/ft. Specific yield of the wells RW -1, RW -2 and RW -3 is 0.025 cu ft/cu ft; PW -8 is 0.030 cu ft/cu ft; PW -9 is 0.020 cu ft/cu ft (Analysis Report for the City of Renton Cedar River Valley Aquifer Test, RH2 Engineering, 1987). The hydraulic conductivity is on the order of 2,500 ft/day assuming an average transmissivity for all the Cedar Valley Aquifer wells of 1.3 mg/day/ft. Recharge is local, both from direct precipitation and subflow. The DOH contamination susceptibility rating of wells located in the Cedar Valley Aquifer is moderate to high. 6.1.2 Downtown Wells The City operates six production wells in the Cedar Valley Aquifer. Wells RW -1, RW -2, and RW -3 each have a pumping capacity of 2,200 gpm and are screened at depths ranging from 50 to 105 feet. Well EW -3 may be used in an emergency. Its capacity is 1,600 gpm and it is screened from 40 to 70 feet below the ground surface. Wells PW -8 and PW -9 have pumping capacities of 3,500 and 1,200 gpm, respectively. The wells are screened at depths ranging from 50 to 105 feet. 6.1.3 Springbrook Springs Approximately 17 percent of City's current water supply comes from Springbrook Springs, located at the extreme southern city limits. A water -bearing sand and gravel layer enclosed in a thick sequence of glacial till intercepts the surface of the hillside at Springbrook Springs. Two infiltration galleries collect and channel approximately 1,000 gpm into the transmission pipeline. Flow measured at Springbrook treatment building vanes over the February 13, 2012 - DRAFT 6-2 pw:IlCa DIINaocumenWClienUWAIRentonl8595A001Deliverahtes/Chapter 6006.dou year with the flow into the system being the highest in the summer months. The flow is kept to below the water right Qi flow of 1,050 gpm via a throttling valve. The Springs have not been extensively studied. The recharge area has been estimated by combining the surface area draining to the Springs with the estimated groundwater recharge area. The latter is based on well driller reports for wells in the vicinity of the Springs_ The DOH contamination susceptibility rating of the Springs is "moderate to high." 6.1.4 Maplewood Production Aquifer The Maplewood production aquifer is located east of the downtown area under the Maplewood Golf Course. It serves as a redundant source of supply for the vulnerable Cedar Valley Aquifer. This aquifer is believed to extend northward into hydrostratigraphically correlated zones beneath the North Uplands. It ranges from 70 to 120 feet thick and is encountered from approximately 135 to 345 feet below the golf course. The Maplewood Aquifer is confined with evidence of some leakage. Gradients are predominantly upward. Estimated transmissivities range from 49,000 to 76,000 gpd per foot with corresponding hydraulic conductivity ranging from 94 to 128 feet per day. Recharge is believed to occur predominantly from the North Uplands while discharge occurs in the Cedar Valley via upward flow to the alluvial aquifer east of the bedrock narrows. Other recharge and discharge points may exist. The DOH contamination susceptibility rating of the Maplewood Aquifer is low. 6.1.5 Maplewood Wells The City has three Maplewood wells (PW -1 1, PW -12, and PW -17), which have pumping capacities of 2,500 gpm, 1,600 gpm, and 1,500 gpm, respectively. These wells are screened at depths ranging from 284 to 344 feet. The City has a permit for a water right at this location for Well 10_ The City has no current plan to develop this well. 6.1.6 well 5A Well 5A is located near the northern city limits east of Lake Washington. This well has a pumping capacity of 1,500 gpm and is completed in a sand and gravel aquifer zone approximately 280 to 390 feet below ground (about -42 to -152 feet mean sea level). The aquifer zone is overlain by stratified glacial deposits of fine to coarse sand and gravel layered with silt and clay. The recharge area for Well 5A is not known but there are some indications that the well may be withdrawing from the Maplewood production aquifer, which is believed to extend northeasterly from the Maplewood area. The DOH contamination susceptibility rating of Well 5A is low. February 13, 2012 - DRAFT 6--3 pw:IlCarollolDccuments/CllenUWA/Rentonl8595AOOIDelWrableslChapter &Ch06.docx 6.2 CONDITION OF SUPPLY SOURCES The City has capital improvement and maintenance programs to upgrade and to maintain its sources in good condition and to comply with water quality criteria. During the last 21 years, the City has upgraded the treatment systems at its Springbrook Springs and all downtown wells. This includes modernization of the disinfection systems and the addition of sodium hydroxide for pH adjustment to reduce the corrosivity of the water. Water treatment improvements to remove hydrogen sulfide, manganese, and ammonia from the Maplewood wells (PW -1 1, PW -12, and PW -11 7) were completed in 2006. The Maplewood treatment system is able to deliver up to 3,000 gpm to the distribution system. The plant has provisions to allow adding additional filters in the future to increase the capacity to 5,500 gpm. There is no plan to provide additional treatment for Well 5A within the next six years. Adding this treatment will be examined again during the next Water System Plan update. Included in this six-year plan are projects to provide Wells EW -3, PW -8 and PW -9, and Springbrook Springs with primary disinfection (log 4 virus removal). The planned method will be by providing additional chlorine contact time to achieve the required combination of chlorine concentration and contact time for primary disinfection. 6.3 CAPACITY OF SUPPLY SOURCES In general, the City's sources are equipped with pumping capacity to deliver the certificated City water rights (or in the case of the Maplewood wells — the permitted Qi flows) to the distribution system_ The installed pumping equipment has the capacity to deliver the water equal to the peak day requirements of the Renton system through 2025. However, without obtaining water rights certificates for the three Maplewood wellfield wells not all of this installed capacity can be utilized. For the current planning period the City plans to use the Maplewood wells as alternate sources only and to revisit perfecting water right certificates during the next planning period. The combined instantaneous withdrawal from the Cedar River sources and the Maplewood sources will not exceed the certificated Qi water rights of the Cedar River sources. The same is true with regard to annual (Qa) withdrawals. At present, Well 5A is only used for back-up supply because of the water quality issues mentioned in Chapter 2 of this plan. Well 4 was decommissioned in 1962. Although the City is currently not utilizing the water right associated with this well, the City could drill a new well in the future if needed. This would provide an additional 170 gpm. During the current planning period the City anticipates that on infrequent occasions the demand will exceed the Qi water rights of the Cedar River sources and Springbrook February 13, 2012 - DRAFT 6-4 pw:f/CarollafDocurnents/Client/'AlRenton18595AODIDeliverah{eVChapter 6/ChO6.docx Springs. During these periods the City plans to meet the demand by purchasing wholesale water from Seattle Public Utilities. See the discussion of this source below. 6.4 WATER RIGHTS The State Water Code, as outlined in Title 90 of the RCW, states that all surface and ground waters of the state are the property of the public. It is, therefore, the policy of the state to promote the use of the public waters in a fashion that provides the maximum benefit arising from both diversionary uses of the state's public water and the retention of waters within the streams and lakes in sufficient quantity and quality to protect in -stream and natural values and rights (90.03.005 RCW): The state takes responsibility for determining who, among the various competing basin stakeholders, is allowed to use, divert, or consume the water. When an application to obtain water rights is submitted to the DOE, the date of receipt of this application establishes the priority of the water right. Prior to the development of a source of supply, a temporary permit is issued by DOE to construct, develop, and test the supply source_ A water right may then be issued following a thorough review process, a determination of the amount of supply that is put to beneficial use, and the impacts on the various other basin stakeholders. This water right establishes the priority use of the water, and becomes an appurtenance to the property. Renton has developed independent water sources in order to maintain greater control over the management and costs of its water supply. Through the development of independent sources of supply the City strives to protect the public health, ensure adequate water supply to meet the requirements of its customers, and support the economic prosperity of the City. Consistent with DOE's procedures for issuing water rights, all of the City's water rights specify a Qi and a maximum Qa. In issuing recent water rights certificates to the City, DOE has conditioned the permits with a limitation on the total withdrawals by the City of 14,809 acre feet per year, recognizing the City's water rights may have an impact on the flows in the Cedar River. The Cedar River is an important regional resource, being the major source of supply for the SPU regional water system and a number of other uses; instream flows are important to anadromous fish and the management of water levels in Lake Washington. Copies of the City's water rights certificates and permits are in Appendix E. 6.4.1 Existing Water Rights The City has 13 water right certificates and five permits. A summary of the City's existing water rights for municipal supply is presented in Tables 6.1 a and 6.1 b, respectively. The total instantaneous flow rate from the certificated rights is 15,152 gpm. The annual rights equal 14,809 acre feet per year, which was set by DOE and is less than the sum of the City's annual rights shown on its certificates.

The City has a permit for Well 10, but it has not yet been developed. Well 4 was abandoned and therefore the City is not using the water right associated with this well. Well 5A is currently not being used due to water quality issues. The water right for Well EW -3 was transferred to the new wells RW -3, RW -1, and RW -2. However, in accordance with the water right certificate, EW -3 continues to be maintained should it be needed to intercept contaminants that could affect the other wells_ EW -3 can also be used as an emergency supply after notifying DOE, in the event that the City's other sources fail. In 2005 the City staff met with the staff of the Northwest Regional Office of the Department of Ecology to discuss finalizing the wellfield management plan (operating plan) for the Maplewood wellfield. At that time the City was informed by DOE that the method for monitoring in -stream flows in the Cedar River that was prescribed in the Reports of Examination for the permits for wells PW -11, PW -12 and PW -17 and which the City had been following was not capable of measuring the impact of the well pumping on the in -stream flows. As a result, the City requested and was granted an extension on the permits for the wells. For this six-year planning period no additional water rights for these wells will be actively pursued. The wells will be used for alternatives to the Cedar River wells (RW -1, RW -2, RW -3, PW -8, and PW -9) combined withdrawals (Qi and 1 or Qa) will not exceed existing water rights for the Cedar River wells. 6.4.2 Forecasted Water Rights Renton's forecasted water rights are shown on Tables 6.2a and 6.2b. The City does not anticipate applying for any new water rights or changes to its existing water rights. In 1997, the City had applied for a change of place for several of its water rights, but since then it has withdrawn those applications. The City's forecasted water rights are the same as its existing water rights with the exception of interties. The City estimates that it will begin to exceed its annual water right of 14,809 acre-feet (equivalent to 13.22 mgd ADD) as soon as 2041 or as late as 2081. The water rights for Well 5A account for 2,320 acre-feet of the 14,809 total. If the City does not pursue additional treatment for Well 5A and does not redevelop Well 4, the available annual water right will be 12,216 acre- feet (equivalent to 10.91 mgd ADD). Under this scenario the City would exceed this usable annual water right as soon as 2027 and as late as 2061. The estimated existing system -wide peak hour demand exceeds the City's instantaneous water rights by 91 gpm (by 2,793 gpm when compared to existing on-line sources). Currently the difference in supply capacity and peak hour demands is met by the City's storage. In 2031, the peak hour demands will exceed the instantaneous water rights by approximately 4,290 gpm (by 7,490 gpm when compared to existing on-line sources). The City plans to address the forecast difference between Qa water rights and annual demand by purchasing water for Seattle Public Utilities. To address the forecast difference between Qi water rights and demand, the City plans to construct additional storage and purchase water from SPU. Additionally, the City will further evaluate the timing of capital improvements to address the water quality problems of Well 5A.

Via the new contract, the City will be a full participant in the regional water conservation program led and managed by SPU. The City's customers will have full access to all the water conservation programs, including rebate programs, the regional program has to offer. The City anticipates a significant decrease in consumption as a result. Additionally, the contract provides for the sale of water to Renton. Renton plans to meet its water demand needs which cannot be met by way of its own sources of supply and / or via storage by purchasing water from SPU. Currently, the City has ten metered connections to SPU transmission mains. See Table 2.3 for specific information. Please refer to Chapter 7, System Analysis and Chapter 9, Capital Improvement Program, for further discussion of projected system deficiencies in the context of source of supply and water rights_ 6.5 INTERTIES The City's interties are described in Chapter 2 as part of the description of existing facilities. The following is a summary of recent upgrades made to some of the interties with SPU: in 2410 a flow control valve and the related SCADA interfaces were added to the Longacres Bow Lake Pipeline connection (PRV Station 24) and in 2011 flow meters and the related SCADA interfaces were added at the Tiffany Park Booster Pump Station (connection to SPU Cedar River Pipeline No 1) and at the Fred Nelson Booster Pump Station (connection to the SPU Bow Lake Pipeline — a.k.a. Cedar River Pipeline No. 4). The City and Seattle Public Utilities signed a wholesale supply contract in May 2 011. The contract provides for SPU to supply water to the City of Renton_ The contract period is 2012 through 2062. The City plans to use this suppl y to meet demand above its existing wate r rights in combination with additional equalizing storage. 6.6 WATER QUALITY PLAN AND TREATMENT The City of Renton performs regular water quality monitoring of its system as described in Chapter 8, Operations and Maintenance, and as required by WAC 246-290-300. The City's water quality at its supply sources, storage facilitiesr and within its distribution system satisfactorily meets state and federal requirements on a regular basis. The City maintains water quality within its system through the following approaches: Routine system flushing within its distribution system in order to maintain satisfactory water quality. 2. A main replacement program to eliminate dead end mains and replace cast iron, asbestos cement, and old steel pipes. February 13, 2012 - DRAFT 6-11 pw.7iCarotlolDocumentslCiien11WA/Rentonl6595AOO1DeliverablesrChapter 6/Ch06 docn 3. Installation of pH meters at all well sites in order to better manage pH and as a result reduce corrosion within the system. It is recommended that the City take the following actions as part of its water quality planning programs: The City should continue to track proposed new water quality laws, such as revisions to the Total Coliform Rule and Lead & Copper Rule, and other rules and regulations being considered by the FPA and DOH (e.g., contaminates being examined UCMR 3) in order to plan for any impacts on its water system and its operation to ensure planning is in place to comply with the potential impacts of these regulations. At this time it is not possible to determine the impact of several proposed rules. The City should continue to implement its corrosion control treatment improvements as necessary to reduce levels of corrosion within the distribution system and private plumbing. 6.6.1 Existing Water Quality A review of the City's water quality testing records indicates that overall water quality is excellent with only minor problems related to aesthetic problems caused by iron, manganese, and hydrogen sulfide. These are secondary contaminants that do not affect public health. Consequently, treatment is necessary only to minimize nuisance and aesthetic related problems such as odor and discoloration_ All testing for bacteria (total coliforms) has been less (1.3%) than the MCL (5%) during the past six years. However the City's water is corrosive, and therefore is treated to prevent corrosion -related water quality problems. 6.6.2 Treatment Gaseous chlorine or sodium hypochlorite (Maplewood wells) is added to all of the City's sources for disinfection and sodium fluoride is also added to prevent dental caries / cavities. Sodium hydroxide is added at Wells RW -1, RW -2, RW -3, PW -8, PW -9, and EW -3, as well as at Springbrook Springs, to raise the pH of the water delivered to the distribution system for pH control. The Maplewood treatment facility treats water from wells PW -11, PW -12, and PW -17.

Converts ammonia in the water to nitrogen gas by reacting it with sodium hypochlorite in a contact basin. February 13, 2012 - DRAFT 6-12 pw,llCarollolDocumentslClienVWAlRentonl8595ACO)Deliverables/Chapter 61ChMdocx A sequestering agent (Aqua Mag) is used in Well 5A to treat for iron and manganese, Since there is also naturally occurring ammonia in the water at Well 5A, the chlorine dosage is set to create monochloramines for disinfection. From an aesthetics perspective the existing treatment is marginal (taste, odor and staining problems still exist). Because of this the source is used sparingly. Aqua Mag is also added at the West Hill Booster Pump Station and PRV Station 20 in the Renton Hill area for corrosion control because of the significant number of cast iron distribution pipelines in these areas. 6.6.3 Water Quality Monitoring The City has implemented a comprehensive and proactive water quality monitoring program. It includes monitoring for operations, regulatory monitoring to meet the requirements of the federal Safe Drinking Water Act, and monitoring to manage the City's aquifers. Monitoring operations measure chlorine levels and pumping rates for each production well, sample polyphosphate levels, and take pH measurements as part of the corrosion control program. Regulatory monitoring measures bacteria, organic and inorganic chemicals, trihalomethanes, and disinfection byproducts radionuclides, lead and copper in the water. The sampling is performed at locations and with the frequencies required by state and federal regulations. Aquifer monitoring is used to identify any contamination and to track water level of the aquifer in compliance with state and federal drinking water rules. This program is described in detail in Appendix N of this Water System Plan Update. Water quality sampling is the responsibility of the water maintenance supervisor and is carried out on a daily basis by a team of utility technicians. In addition to ensuring that water treatment and maintenance are performed effectively, the water maintenance supervisor is responsible for ensuring that monitoring is carried out and for managing water quality data and records both for routine and special monitoring programs. The Water Maintenance Division maintains a water quality laboratory located at the City shops building at 3555 SE 3rd Avenue. The City's water quality laboratory is equipped to do analysis for turbidity, chlorine residual, fluoride residual, pH, and temperature. Microbiological and certain physical and chemical parameters are analyzed by locally contracted commercial laboratories. This approach has worked well for meeting the City's sampling and testing needs. The City also maintains nine mechanical type well sampling pumps for extracting water quality samples from monitoring wells. These pump units can be used for the collection of all types of water quality samples, including volatile organic chemicals. A detailed description of the water quality sampling methods, the sampling locations, sampling frequency, and record keeping procedures are listed in the Drinking Water Quality Monitoring Program included as Appendix H. The estimated costs for the City's water quality monitoring are included in Chapter 8, Operations and Maintenance. February 13, 2012 - DRAFT 6-13 pw:I)Carolia/DocirmntFJClien VWAIRenton16595ADOIDeliverables/Chapter 6)ChD6.docx 6.6.4 Corrosion Control Program 6.6.4.1.1 Lead and Copper Rule In the past there were relatively high copper levels, and occasionally high lead levels, at home taps because of the relatively low pH of the downtown wells (RW -1, RW -2, RW -3, PW -8, PW -9, and EW -3) and Springbrook Springs water supplies. The raw water pH range is 6.3 to 6.6 for the downtown wells and about 7.2 for the Springs. Treatment with gaseous chlorine depresses the pH to slightly below the 6.3 to 6.6 range. Without pH adjustment, the levels in the distribution system typically range from 5.9 to 6.4. Water with pH less than 7.5 is aggressive in leaching copper and lead from the pipelines. A secondary corrosion -related concern is iron levels and associated colored water occurrences in areas of the distribution system with old, unlined cast iron and steel pipe. Lower pH levels often cause heavy corrosion of the iron and scale buildup, which can result in red water complaints when flushing or if there are surges in flow in the pipelines. 6.6.4.1.2 Corrosion Protection: Source of Supply As a result of the low pH levels, the City has added corrosion control treatment to its downtown wells and Springbrook Springs. Sodium hydroxide is added to these sources to raise the pH to between 7.5 and 7.7. The pH of the raw water from the Maplewood wells (PW -11, PW -12, and PW -1 7) is approximately 8.1 and that of the treated water is about the same. Well 5A water has a pH of approximately 8 and phosphate inhibitor can be added. The Corrosion Control Recommendation Report (March 1995) found that no additional corrosion control treatment processes are required for these sources. 6.6.4.1.3 Corrosion Protection: Distribution Mains Since about 1976 the City has required that all water mains installed in the City be cement - lined ductile iron pipe. Additionally, since 1980 the City has required that water mains installed in high resistivity soils be wrapped in polyethylene. Beginning in 1994, the City specifications have required that all water mains be wrapped in polyethylene. These requirements were established to reduce the internal and external corrosion of water mains. In a few of the locations where the City's water mains are within the influence area of other utility lines that are protected with impressed current cathodic protection systems, the City's water mains are electrically bonded and/or protected with sacrificial anodes. Test stations are installed. Testing is random and infrequent at this time. 6.6.4.1.4 Corrosion Protection: Steel Reservoirs and CT Pipeline Three of the City's seven steel reservoirs are protected with impressed current cathodic protection systems (Mt Olivet, Highlands 565, and Rolling Hills 590). The West Hill reservoir has an impressed current cathodic protection system installed, but so far there has not February 13, 2012 - DRAFT 6-14 pw:IfCarollolDocumentslClientfWA/Rentonl8595AOOIDeliverableslChapter 6006.dou been a need to energize it. The seven reservoirs are inspected by a corrosion control consultant approximately every five years. The inspections examine the protective coatings as well as the cathodic protection systems. The interior and exterior protective coatings are repaired and/or replaced as recommended by the consultant. Impressed current systems are checked annually. Adjustments and maintenance actions are made to the impressed current systems based upon the consultant's recommendations. The CT Pipeline used to provide primary disinfection for wells RW -1, RW -2, and RW -3 has an impressed current cathodic protection system installed but there has not been a need to energize it. 6.7 STATE AND FEDERAL REGULATORY REQUIREMENTS This section presents the current water quality standards of DOH and the EPA through the Safe Drinking Water Act (SDWA). The City should continue to track new water quality regulations, offer comments on draft rules as appropriate, and plan for any additional monitoring and/or treatment as may be required. The following subsections contain descriptions of specific rules that are new or pending or have special requirements for the City in addition to requirements of the federal SDWA. All rules that are included in the SDWA and that apply to Renton are shown in Table 6.3. Water Quality Monitoring Report for the Year 2011 (Appendix H) provides an illustration of the current monitoring requirements for the system as well as State Waivers that currently apply to the system. 6.7.1 Total Coliform Rule The City's water system is classified as a Group A public water system according to DOH. Drinking water samples must be collected for bacteriological analysis from representative points in the distribution system at regular time intervals. The number of water samples is dependent upon the population being served by the system. The City is required to have a Coliform Monitoring Plan on file and approved by DOH. This plan identifies coliform monitoring locations and sampling procedures. The City's Coliform Monitoring Plan is included as Appendix A of the Drinking Water Quality Monitoring Program, Appendix H of the Water System Plan. Testing for bacteria (total coliforms) has been less than the MCL (5%) during the past six years. The range has been between 1.0% (in 2010) and 3.3% (in 2008) with the median being 1.5%. 6.7.2 Stage 4 & 2 Disinfectants and Disinfection Byproducts Rules Because Renton uses chlorine for disinfection, it needs to meet the requirements of the Stage 1 and Stage 2 Disinfectants / Disinfection Byproducts Rules (D/DBPR). It meets these requirements of the Stage 1 D/DBPR and has been collecting and testing samples in preparation for meeting the Stage 2 D/DBPR. For the City of Renton routine monitoring for the Stage 2 D/DBPR begins on October 1, 2012. See Appendix H, Drinking Water Quality Monitoring Program of this plan for details.

The City is complying with the rule. The City plans to add 4 -log treatment of viruses and compliance monitoring to the following sources: PW -8, PW -9, EW -3, and Springbrook Springs. The following sources already have 4 -log treatment of viruses and compliance monitoring: RW -1, RW -2, RW -3, PW -11, PW -12, and PW -17. See Chapters 2, Existing System and Chapter 9, Capital Improvement Program for discussion of the addition of treatment and Appendix H, Drinking Water Quality Monitoring Program of this plan for details_ 6.7.4 Radionuclides Rule The City is complying with the rule. During the last sampling and testing period (.dune 2010) the levels of Gross Alpha particles and Radium 228 were below the detection limit. See Appendix H, Drinking Water Quality Monitoring Program of this plan for details. 6.7.5 Inorganic Chemical Analysis The City is required by DOH to take samples for inorganic chemical analysis at the source after treatment_ The complete inorganic chemical and physical analysis shall include the primary and secondary chemical and physical drinking water contaminants. The analyses on its well sources must be performed is every three years, except that nitrate must be monitored annually. 6.7.6 Organic Chemical Analysis Volatile organic chemicals (VOCs) and synthetic organic chemicals (SOCs) are monitored in all of the City's wells. Organic chemical monitoring standards require one sample every 3 months during the first 12 months. However, if no contaminants are detected in the first sample of a groundwater source, the purveyor shall sample that source once more during the 12 -month period. If no chemicals are verified after the initial 12 months of monitoring, the purveyor shall monitor each source at least once every 36 months. Water must be sampled from each source and must be collected after the water has been treated. February 13, 2012 - DRAFT 6-18 pwJlCamllolDocuments7GientNVAlRenton18595AD01Deliverables!Chapter 6/Ch06.dxz Recent chemical analyses of the City's supply sources show no contamination from VOCs or SOCs. The City must test for trihalomethanes at all wells once a year since they are chlorinated. In the late 1980s tetrachloroethylene (PCE) was detected in the downtown wells. The source was found to be condensate from a dry cleaning business that leaked into the ground through a broken side sewer. In 1997 PCE was detected in the downtown wells again_ This time the source was determined to be a wash water basin at the Stoneway Concrete site adjacent to Cedar River Park. Well 8 was continuously pumped to waste to clear up the contamination. Recent VOC tests of the downtown wells do not show any PCE contamination. Positive tests for VOCs occurred at PW -5A in 1994. The positive sample in PW -5A was determined to be from a poorly cured coating on the well casing. The City cleaned and purged the well and sandblasted the coating. The City flushes this well for approximately 20 minutes each time it is used prior to connecting to the system. Since this operational modification was implemented, no VOCs have been detected. The state has a susceptibility assessment program which enables water systems to bypass the required quarterly sampling for VOCs the first year. Reduced monitoring is allowed if a susceptibility assessment of the water system indicates a low or moderate vulnerability to contamination. The City submitted a susceptibility assessment to the DOH. Table 6.7 of the susceptibility assessment lists the ratings given to each well by the DOH and the required testing. These susceptibility ratings are also shown in the Water Quality Monitoring Report for the Year 2011 (Appendix H). Although the susceptibility of Well 5A to contamination is rated low, quarterly testing for VOCs continues to be required (when the well is being used) because of the earlier positive test. Ongoing quarterly testing is performed at the downtown wells and the Springs because of the medium to high vulnerability of these sources to contamination. The state has an area waiver program for SOC monitoring. Under this program, the City can reduce its SOC testing requirements (and costs) at its wells by participating in the funding of the area waiver program. Several City wells have received waivers to testing for SOCs (PW --5A, PW -11, PW -12, and PW -17). Renton is participating in the State Area Waiver Program for sources that did not receive a SDC waiver. Consequently, SOC testing at these wells has been reduced; the testing program for these sources is described in the City's Drinking Water Quality Monitoring Program, Appendix H. 6.7.7 Lead and Copper See discussion above and Appendix H, Drinking Water Quality Monitoring Program of this plan for details. 6.7.8 Future Regulations The City is monitoring the developments surrounding the following potential rules and rule changes: February 13, 2012 - DRAFT 6-19 pw:f/CiarolloiDocumentslClienYWiVRentonl8595AOOIDeliverahleslChapter 67Ch0UDa • Revisions to the Total Coliform Rule_ • Revisions to the Lead and Copper Rule. • Proposed Perchlorate Monitoring — not anticipated to effect the City of Renton. • Unregulated Contaminant Monitoring Rule 3 (UCMR3) List of Contaminants. Changes in the recommended fluoride dose. 6.8 WELLHEAD PROTECTION PROGRAM The 1986 amendments to the federal Safe Drinking Water Act mandated that every state develop a wellhead protection program to protect ground waters that serve as drinking water sources for public water supplies_ In 1994 DOH adopted Washington Administrative Code 246-290, which directed Group A public water systems using wells or springs to implement wellhead protection measures. The City of Renton prepared its Wellhead Protection Plan, which was approved by DOH in December 1999. An updated Wellhead Protection Plan is included in this Water System Plan as Appendix L. DOH stipulates that local wellhead protection programs shall, at a minimum, include the following elements: • A completed susceptibility assessment. • A delineated wellhead protection area for each well, wellfield, or spring. • An inventory of contamination sources located in the wellhead protection area that have the potential to contaminate wells or springs. • Documentation that delineation and inventory findings are distributed to property owners and regulatory agencies. • Contingency plans for providing alternate sources of drinking water in the event that contamination does occur. • Coordination with local emergency responders for appropriate spill response measures. Compliance with Wellhead Protection Program requirements is part of a broader City effort referred to as the "Aquifer Protection Program." The Aquifer Protection Program was established in 1988 when the Renton City Council designated Aquifer Protection Areas. The City continues to refer to its program as the "Aquifer Protection Program" rather than "Wellhead Protection Program" since elected officials and citizens are familiar with this term after many years of public education. It should also be noted that the Aquifer Protection Program substitutes the terms "1 -year Capture Zone," "5 -year Capture Zone," and 10 -year Capture Zone," as appropriate, for the term "Wellhead Protection Area." February 13, 2012 - DRAFT 6-20 pw:llCamllofDccumentuClien VWNRenton18545AQ0lCeliverableslChapter 61Ch06.dccx The City of Renton obtains most of its drinking water supply from shallow aquifers and a spring that are susceptible to contamination. The aquifer has received "sole source" designation from the EPA. As part of its Aquifer Protection Program, the City has enacted aquifer protection regulations to protect the aquifers used as potable water supply sources from contamination by hazardous materials. The regulations include restrictions on hazardous material quantities, storage, and handling; land use restrictions; facility operating standards; construction activity standards; fill quality standards; and other measures intended to prevent contamination. Other components of the Aquifer Protection Program include public education, aquifer water quality and level monitoring, coordination with emergency responders, and coordination with surrounding land use authorities on groundwater protection issues. Please refer to Appendix L for further details. 6.9 SYSTEM RELIABILITY Renton continues to meet its responsibility to its customers and as a water purveyor by addressing the reliability of the water system through the quality and condition of its facilities described earlier in this chapter, through system redundancy; and through the development and implementation of its Vulnerability Assessment and its Water Shortage Response Plan. 6.9.1 Reliability Efforts The City continues to provide reliable water service to its existing customers and plan for long-term reliability of its system for its sources and its distribution network. The City's primary supply is from its downtown wells, which provide water from the Cedar Valley Aquifer and Springbrook Springs. There is an emergency well (EW -3) that can be used in the event that the main wells are unavailable. In addition to the Cedar Valley Aquifer, the City can supply its system from two different sources within its service area, the Maplewood Aquifer (supplemental; not additive) and Well PW -5A. In 2007 the City added emergency electrical generation facilities to supply power to Wells RW -1, RW -2, and RW -3 and to Mt Olivet and North Talbot booster pump stations. See Chapter 2, Existing System and Chapter 9, Capital Improvements Program for further discussion of existing and planned emergency backup power. In addition to its own sources of supply, the City also has eleven existing interties with three neighboring water utilities (plus two 10 -inch supply lines to the Renton Boeing Plant from Seattle). The City is also actively participating in and is studying other options for reducing demands and/or providing additional supply. These options include the City's ongoing Conservation February 13, 2012 - DRAFT 6-21 pw:llCamilolDocumenWDienVWAIRenton18595AD01DeliverableslChapter 6006.docx Plan, a future aquifer recharge study, and the continuing examination of opportunities for the use of reclaimed water. 6.9.2 Water Shortage Response Planning The City developed a Water Shortage Response Plan in 1989 to meet its responsibility for planning for emergencies or other short- or long-term shortages that may occur. The City will update its Water Shortage Response Plan in 2012. 6.10 LONG-RANGE WATER SUPPLY PLANNING The City has been decisive and progressive in its water supply planning. As discussed elsewhere in this chapter, the City has pursued and secured independent sources of supply as well as supplemental sources and wholesale supply_ The City has pursued its independent acquisition of water sources in order to maintain control over this utility, which is vital to the public health and economic well being of its customers. An important consideration has also been concern with the cost of water supply and the desire to keep water rates low and competitive with neighboring systems and with the region as a whole. As discussed above the predicted range in time that the City's annual water rights will meet demand is large. Whether or not Well PW -5A is available as a source affects that predicted range. A key decision to be made is whether or not to invest in additional treatment for Well PW -5A or purchase larger amounts of water from SPU. Before investing a large amount of money for treatment of the PW -5A water the City will need to better determine the extent and capacity of the aquifer upon which the well draws. The City will pursue several different approaches to supplement its peak demand requirements (20 -year and longer planning period). This includes expanded conservation efforts and strategies, additional storage, the purchase of wholesale water from SPU, perfecting additional Qi water rights (Maplewood wells) and the possible use of other technologies such as reclaimed water and aquifer recharge. The City actively participates with other water systems on regional planning, supply, and operating issues. For example, Renton is a member of the East King County Regional Water Association and the Water Conservation Coalition of Puget Sound. Another example is the City's participation in the recent Puget Sound Regional Water Supply Outlook Study, which assessed the supply sources of the Central Puget Sound Region, explored ways that systems can support each other, and evaluated regional supply options to meet future needs. Under the City's new contract with SPU, Renton will be participating in the Seattle Regional Supply System (SRSS) via its attendance and participation at SRSS Operating Board meetings. February 13, 2012 - DRAFT 6-22 pw:llCarollolDocumerls/ClientWNRenicnI8595AOOIDeliverables!Chapter 6IChO6.docx 6.10.1 Regional Water Supply Issues The City of Renton draws its supply, primarily from aquifers in the lower reaches of the Cedar River Watershed. The Cedar Valley aquifer in particular is relatively shallow. However, there is no evidence from studies conducted to date that the City's water use has an impact on flows in the Cedar River. The Muckleshoot Indian Tribe has an interest in the Cedar River and its fishery resources. The Tribe is concerned with low stream flows that can affect water quality. Renton is monitoring the River as a condition of its water rights and will continue to cooperate with the other parties in the management of this resource. SPU is the regional water purveyor for much of King County. It serves most of the cities and water districts in the vicinity of Renton. Renton itself has agreements with Seattle for supply as already discussed. In recent years, SPU has implemented a successful conservation program that has delayed the need for new sources. The water utilities in the Puget Sound Region have individually and collectively addressed future sources of supply to meet their future needs. SPU has constructed a 120-mgd water filtration plant on its Tolt River source. This improvement in water quality meets current water quality standards and allows SPU to make better use of the Tolt source to meet existing and future demands. The City of Tacoma is the regional system to the south, serving much of Pierce County and some areas in south King County. Tacoma has completed construction of its second supply project. This involves a second supply pipeline from its Green River source which adds another 60 cfs of supply to the Tacoma system. The Tacoma Second Supply Project serves a number of water districts in south King County, some of which are also supplied by SPU. See: http:l/www.m)dpu.or-gAacomawatertwater-system/supply,/regional-water- suoDly/Default.htm The Growth Management Act requires cities in Washington State to prepare 20 -year plans for their future development, including the provision of adequate water supply to support this growth. This has raised concerns with many water utilities because they are often not consulted when the land use planning and economic development decisions are made for GMA and many water systems are reaching the capacity of their sources and don't have the necessary future capacity to meet GMA projections. In addition, the process of obtaining water rights in Washington State has become extremely difficult and time- consuming because of concerns over instream flows and the suspected influence of groundwater withdrawals on stream flows. The current situation has prompted water systems in the Central Puget Sound area to pursue new source development as a top priority. The Cascade Water Alliance was created several years ago with participation of many of the water systems in King County to pursue new regional supplies as an alternative, or in conjunction with SPU and Tacoma. Many of February 13, 2012 - DRAFT 6-23 pw:l7CarollolDocumenWDienUWAIRentont8595A00IDeliverahles!Chapter 6006.docx the same systems have also participated in the Puget Sound Outlook Study, which included water utilities in King, Pierce, and Snohomish Counties. As a resuft of planning by individual water utilities and the efforts of the consortiums mentioned in the previous paragraphs, a number of regional projects have been proposed. The following list describes two of these regional solutions: The Cascade Water Alliance has purchased water rights formerly held by Puget Sound Energy for hydroelectric generation on the White River, including storage in Lake Tapps and is currently working to get approval to use Lake Tapps as a municipal water supply. The Snohomish River Regional Water Authority acquired a 36-mgd water right formerly used by Weyerhauser (S1 -10617C) for its now abandoned plant in Everett. Various schemes have been proposed for delivering this water to utilities, including some in King County. Use of the water right continues to be under study. The water supply situation is continually changing with alternatives proposed, studied, and sometimes put on the shelf. A number of other alternatives have been considered including the North Fork Tolt River, Snoqualmie Aquifer under the Middle Fork of the Snoqualmie River, the North Fork Snoqualmie River, direct withdrawal from Lake Washington, and even sources as far away as the Skagit River. At the present time, none of these appear to be in serious contention as the next source due to water rights or environmental, cost, or institutional issues_ As a participant in forums proposing new supplies, the City of Renton is keeping itself involved and informed of new developments. It will make decisions and act as appropriate to preserve its current supply and/or to participate with other utilities in new or alternative source development. 6.11 RECOMMENDED WATER SUPPLY IMPROVEMENTS Recommended improvement projects for water supply can be grouped into the main areas of interties, water quality, and reliability. Specific projects associated with the supply projects are included in Chapter 9. It is recommended that the City maintain and/or renew its existing intertie agreements with adjacent purveyors as well as pursuing additional new interties in order to improve reliability and to help supplement future peak demands. This would include renewing its agreement with Seattle. System reliability can be improved through several approaches that include security and system redundancy. The City has identified several security improvements that are included in its six-year CIP. As redevelopment occurs, the City can improve system reliability by February 13, 2012 - DRAFT 6-24 pw:!lCarollUDocementslClienWVAIRentan18595AOOiDeliverables/Chapter 61Ch06.docx considering options for new PRVs and other control valves that provide additional supply to zones. Additional possible projects for improving supply reliability are aquifer recharge and the use of reclaimed water. The City has not investigated artificial aquifer recharge, but plans to proceed with a study within the next 20 years to look at the feasibility of such a project_ The use of reclaimed water has been attempted by the City with limited success to date. Feasible alternatives for using reclaimed water are not anticipated within the next six years. However, King County plans to perform a countywide reclaimed water feasibility study in which the City will participate, to identify any other potential reclaimed water users.

The evaluation of the pipeline capacities was conducted using the City's hydraulic model. Evaluations of the remaining utilities were conducted in Microsoft Excel. Improvements identified in this chapter are summarized in the Capital Improvements Plan (CIP) in Chapter 9. 7.2 OPERATIONAL AREAS For the purpose of evaluating storage and pumping capacity, the City's water distribution system was divided into seven different operational areas, which feed fifteen pressure zones. Table 7.1 summarizes the various operational areas and their associated pressure zones. Figure 7.1 provides an overview of the City's operational areas and pressure zones; Figure 7.2 presents the hydraulic profile color -coded according to operational areas.

The City's design criteria is to provide sufficient reliable sources / pumps to provide the maximum day demand (MDD) for each operational area with the largest pump or source out of service. For the purpose of this study, the term 'reliable" refers to a pump station or source of supply that has back-up power. The term "redundant" refers to a pump station or source of supply that can meet demands with the largest pump or well out of service. This section describes the capacity of the existing system and system recommendations to meet identified deficiencies. 7.3.1 Existing System The source and pumping capacity of each operational area was compared to the projected MDD for 2017 and 2031 in the following sections. 7.3.1.1 Valley The Valley reliable sources include the Downtown Wells (total capacity of 11,400 gallons per minute (gpm) from RW1, RW2, RW3, PW8, PW9 and standby EW -3), Springbrook Springs (1,050 gpm) and the SPU connection at Bow Lake (2,800 gpm). The total reliable source capacity for the Valley Operational Area is 15,250 gpm. The largest of these sources is Well 8 at 3,500 gpm. When Well 8 is taken out of service, emergency well EW -3 can be placed in service (at 1,500 gpm) bringing the reliable, firm capacity of the Valley Operational Area to 13,250 gpm. In addition to serving the Valley Operational Area, the Valley sources also provide source capacity to all the higher zones with the exception of the West Hill 495 operational area_ For this analysis, the West Hill Operational Area is assumed to be served by the Dimmit BPS and the SPU connection as described in the following section_ The Valley sources need to supply the higher zones with 5,763 gpm in 2017 and 7,396 gpm in 2031. These supplies need to be accounted for when comparing the Valley sources with the Valley's MDD. This comparison is summarized in Table 7.2. As shown in the table, the available source capacity within the Valley is sufficient to fulfill the MDD of the Valley Operational Area and the higher Operational Areas that depend on the Valley sources_ 7.3.1.2 West Hill 495 The reliable sources within the West Hill 495 Operational Area include a 700-gpm SPU connection at Station 38 (PRV 35), 1,000 gpm from the West Hill BPS (the West Hill BPS only has sufficient back-up power for 1,000 gpm), and 1,600 gpm from Skyway's Dimmit BPS. The total reliable source / pump capacity of the West Hill 495 Operational Area is 3,300 gpm. Of these sources, the largest pump / source is the 1,000 gpm pump from the West Hill BPS, bringing the firm, reliable pumping ! source capacity to 2,300 gpm_ This February 14, 2012 - DRAFT 7-4 pw:llCarellciDocumenLslClientPNA/Renton1B595AOCIDeiiverahleslChapter 71ChO7.docx amount exceeds the MDD of the West Hill 495 Operational Area in both 2417 and 2031. A comparison of the projected MDD and the redundant source capacity for the West Hill 495 Operational Area is presented in Table 7.3, and demonstrates that there is sufficient capacity to meet the MDD in the West Hill 495 Operational Area.

Largest source = Downtown Well 8 (3,500 gpm). If this well were to fail, its capacity could be partially replaced by Emergency Well EW -3 (at 1,500 gpm). 2. Assumed that the Highlands 565 MDD is reduced by 1,500 due to supply from Maplewood. The use of this supplemental supply plus 1,500 gpm from Emergency Well EW -3 (total of 3,000 gpm) used in conjunction with the remaining working Downtown wells is 500 gpm less the than the Qi water rights of the Cedar River Valley wells (11,400 gpm). 3. Sufficient capacity can be provided from the Valley, so that the SPU source is not required.

Largest source = West Hill BPS since the largest pump at the Dimmit BPS is limited to a capacity of 700 gpm. 7.3.1.3 Highlands 435 The reliable sources within the Highlands 435 Operational Area include the Houser Way Booster Pump Station (BPS) at 4,800 gpm, and the Mt Olivet BPS at 4,350 gpm. The total reliable source / pump capacity of the Highlands 435 Operational Area is 9,150 gpm. Of these sources, the largest pump / source is the 2,050 gpm pump from the Houser Way BPS, bringing the firm, reliable pumping / source capacity to 7,100 gpm. In addition to serving the Highlands 435 MDD, the Highlands 435 sources also supply the Highlands 565 Operational Area. The Highlands 565 Operational Area can also be supplied from the Maplewood system (at 1,500 gpm, summarized in the following section). The Highlands 435 sources needed to supply the Highlands 565 Operational Area were determined by subtracting 1,500 gpm from the Highlands 565 MDD. The Highlands 435 sources need to supply the higher zones with 1,583 gpm in 2017 and 2,438 gpm in 2031. The comparison of the Highlands 435 sources to the Highlands 435 and 565 demands is summarized in Table 7.4. As shown in the table, the available source capacity within the Operational Area is sufficient to fulfill the MDD of the Highlands 435 Operational Area.

Assumed that Maplewood would supply 1,500 gpm of the MDD from the Highlands 565 Operational Area. 7.3.1.4 Hichlands 565 The reliable sources within the Highlands 565 Operational Area include the Highlands BPS (3,900 gpm) and the Maplewood system (1,500 gpm). The total reliable source capacity is 5,400 gpm. The largest source / pump within the operational area is a 1,500-gpm pump at the Highlands BPS, bringing the operational area's firm, reliable capacity to 3,900 gpm. The Maplewood system can either serve the Highlands 565 Operational Area or the Rolling Hills 590 Operational Area. For this analysis, it is assumed that it serves the Highlands 565 Operational Area. Additionally, the Maplewood Wells are considered part of the City's Cedar River Well system, which includes the Downtown wells (in the Valley). The total water rights for the Cedar River wells is 11,400 gpm. It was assumed that for the Valley, Well 8 was out of service (3,500 gpm) and Emergency Well EW -3 was in service. The total capacity used by the Valley for this analysis was 9,400 gpm, which leaves sufficient capacity within the Cedar River water right for 1,500 gpm from the Maplewood system. The comparison of the source capacity and demands for the Highlands 565 Operational Area is summarized in Table 7.5. As shown in this table, the Operational Area has sufficient source capacity for 2017, but will be deficient in capacity by 2031.

For this identified deficit, it is recommended that back-up generators be added to the Monroe Ave BPS, which currently has an unreliable capacity of 2,500 gpm. Additionally for the West Hill 495 Operational Area, the City does not have sufficient sources / pumping within the zone to provide the MDD without resorting to the emergency intertie with Skyway. It is recommended that the City also add back-up power to the remaining two pumps at the West Hill BPS to avoid having to use the Skyway intertie for these emergency conditions. 7.4 STORAGE ANALYSIS The City of Renton reservoir storage requirements are based on the water system configuration, seasonal and daily variation in water -use patterns, and the reliability of various water system components. The following section describes the four components of storage, summarizes the capacity of the existing system to meet the storage needs of each operational area, and presents recommendations to address any identified storage deficits. 7.4.1 Elements of Storage Water storage volumes are comprised of four categories including Operational Storage, Equalizing Storage, Emergency and Fire Flow Storage, and Dead Storage. These components of storage are shown schematically in Figure 7.3 and are described below. 7.4.1.1 Operational Storage Operational storage is the volume used on a day-to-day basis to supply the water system while the sources of supply are in the "off' position. This volume is dependent on the sensitivity of the water level sensors controlling the pumps and is designed to prevent excessive cycling of the pump motors. The operational storage for the City's reservoirs was determined from the settings in the hydraulic model. These operational volume requirements are summarized in Table 7.9.

The State of Washington Administrative Code (WAC) 246-290-253 requires that Equalizing storage be provided to provide peak demands and WAC 246-290-230 (5) states: New public water systems or additions to existing systems shall be designed with the capacity to deliver the design PHD quantity of water at 30 psi (210 kPa) under PHD flow conditions measured at all existing and proposed service water meters or along property lines adjacent to mains if no meter exists, and under the condition where all equalizing storage has been depleted. Equalizing volume requirements were calculated for each reservoir based on the following equation: 150 min x (PHD — firm, reliable sources) where the PHD was calculated based on peak hour to max day peak factors measured for each operational area. Table 7.10 summarizes the calculated equalizing volumes for each operational area for the years 2017 and 2031.

Fire Storage Emergency storage volumes are required to supply reasonable system demands during a system emergency, such as the disruption of the water supply. Disruptions could be caused by transmission pipeline or equipment failure, power outage, valve failure, or other system interruptions, as discussed in Chapter 3. The computation of emergency storage requirements includes consideration of reasonable system disruptions that can be expected to occur within normal planning contingencies as discussed previously. Other major system emergencies, such as those created by an earthquake, are covered under emergency system operation planning. The Water System Design Manual (August 2001, DOH) recommends that, at a minimum, the emergency storage not be less than 200 gal/ERU. This factor was used to calculate the emergency storage requirements. Table 7.11 summarizes the Emergency storage volume requirements for 2017 and 2031.

WAC 246-290- 230 (6) states that: If fire flow is to be provided, the distribution system shall also provide MDD plus the required fire flow at a pressure of at least 20 psi (140 kPa) at all points throughout the distribution system, and under the condition where the designed volume of fire suppression and equalizing storage has been depleted. February 14, 2012 - DRAFT 7-15 pw:IiCarollo/DocurTenWClientNAlRenlorVB595A0a1QeliverableEdChapter 71CM.docx Fire flow demand is the quantity of water required for fire fighting as defined by applicable water system criteria and fire codes. Fighting fires often places the largest demands on a water system because a high volume of water must be supplied over a short time. Such demands require each component of the system to operate at its optimal condition. Consequently, the Washington State Insurance Service Office (ISO) recommends that water systems be designed to convey fire flows during a period of MDD with one major facility out of service. Fire flows required by existing structures vary within the water service area and are discussed in more detail in Section 7.5. The current maximum fire demand for each major operational area is shown in Table 7.12. These fire demands were calculated as the maximum fire demand in each of the pressure zones that make up the operational area.

Storage volume is considered dead if it is located below the outlet pipe and cannot be used because of system hydraulic limitations, or it cannot be used because of water quality problems associated with the volume in this lowest portion of the tank.

Olivet Reservoirs, which have a combined available storage volume of 5.8 MG (8.0 MG less the total dead volume of 2.2 MG). Table 7.15 summarizes the storage analysis for the Valley. Based on the analysis presented in Table 7.15, the Valley has sufficient storage through 2031. However, the operational and equalizing storage needs to be available at a minimum of 30 psi for the highest resident served. The total available reservoir volume available at 30 psi is only 0.12 MG, 1.06 MG less than is required in 2017 and 1.11 MG less than is required in 2031.

Table 7.16 summarizes the storage analysis for the West Hill 495 Operational Area. With the existing reliable sources and reservoirs, the West Hill 495 Operational Area does not have sufficient storage through 2031. However, as shown in Table 7.3, the West Hill 495 Operational Area does have excess pumping capacity and can pump the PHD for the Operational Area (1,449 gpm in 2017 and 1,714 gpm in 2031). This excess pumping capacity can eliminate the need for equalizing storage (0.08 MG in 2017 and 0.10 MG in 2031), resulting in sufficient storage within the West Hill 495 Operational Area.

Table 7.18 summarizes the storage analysis for the Highlands 565 Operational Area. With the existing reliable sources and reservoirs, the Highlands 565 Operational Area does not have sufficient storage for 2017 or 2031. In 2017, the Highlands 565 Operational Area has sufficient pumping to offset a portion of the equalizing storage volume (0.12 MG).

Table 7.19 summarizes the storage analysis for the Rolling Hills 590 Operational Area. With the existing reliable sources and reservoirs, the Rolling Hills 590 Operational Area does not have sufficient storage for 2017 or 2031. As shown in Table 7.6 the Rolling Hills 590 Operational Area has sufficient pumping capacity to pump the PHD (729 gpm in 2017 and 779 gpm in 2031) and thus eliminate the equalizing storage volume (0.02 MG). Additionally, because the Rolling Hills BPS is equipped with Auto -Start, Auto -Transfer back-up power, the excess capacity from the BPS can be used to pump fire flow from the Rolling Hills 490 Reservoir. In 2017, the Rolling Hills February 14, 2012 - DRAFT 7-21 pw:llCarollWpocumenis7GienUWNRentonl8595Ap01Delirerables/Chapter 71CW-docx BPS has 2,771 gpm of excess capacity, which can be used to offset 0.67 MG of emergency 1 fire storage over a period of 4 hours. In 2031, the Rolling Hills BPS has 2,721 gpm of excess capacity, which can be used to offset 0.65 MG of emergency ! fire storage over a period of 4 flours_ The sum of these two storage offsets (0.69 MG in 2017 and 0.67 MG in 2031) is less than the deficit identified in Table 7.19, and additional storage is still needed.

Table 7.21 summarizes the storage analysis for the Talbot Hill 350 Operational Area. With the existing reliable sources and reservoir, the Talbot Hill 350 Operational Area does not have sufficient storage for 2017 or 2031. As shown in Table 7.8, the Talbot Hill 350 Operational Area has sufficient pumping capacity to pump the PHD (830 gpm in 2017 and 890 gpm in 2031) and thus eliminate the equalizing storage volume (0.02 MG). Additionally, since the 500-gpm pump from the North Talbot BPS has Auto -Start, Auto -Transfer back-up power (and under this analysis is not being used to pump the MDD or PHD), the excess capacity from the BPS can be used to pump fire flow from the Valley. This excess capacity can be used to offset 0.12 MG of emergency / fire storage over a period of 4 hours. The sum of these two storage offsets (0.14 MG) is 0.03 MG less than the deficit identified in Table 7.21.

The identified storage deficits can be mitigated by constructing additional storage. However, in some cases small improvements to existing infrastructure, such as adding back-up power, was shown to alleviate the storage deficiencies rather than adding storage. All recommended projects are summarized below. February 14, 2012 - DRAFT 7-23 pw:llCarollo/DmumenWClienUVVkRentonl8595A001Deliverables!Chapter DCh07.docx 7.4.4 2017 Improvements • Valley Operational Area: — Construct a new 1.0 -MG tank for the Valley Operational Area to improve the ability to serve the highest customers during an emergency. This project could be delayed if the City enters negotiations with SPU for additional supply to this zone. — Alternatively, the City could rezone the Valley 196 Zone to eliminate the high - elevation customers_ • Highlands 565 Operational Area: — Install back-up power generators at the Monroe Avenue BPS to allow storage to be provided from the Highlands 435 Zone to the Highlands 565 Zone (will also improve pumping capacity for long-term). Rolling Hills 590 Operational Area: — Add back-up power to the Maplewood BPS to increase pumping capacity from the Rolling Hills 490 Zone to the Rolling Hills 590 Zone. — Add auto -start, auto -transfer, and back-up power to the Rolling Hills BPS such that three pumps can be operated at the same time. Talbot 350 Operational Area: — Add auto -start, auto -transfer back-up power to South Talbot BPS to increase pumping capacity and reduce the storage deficit. 7.4.5 2031 Improvements • Highlands 565 Operational Area: — Construct a new Highlands 435 Reservoir to serve both the Highlands 435 and Highlands 565 zones. • Rolling Hills 590 Operational Area: — Add auto -start, auto -transfer to the Maplewood BPS to serve fire flow from the BPS. 7.5 DISTRIBUTION SYSTEM ANALYSIS The calibrates! InfoWater model of the City's Distribution System was used for system analysis of future planning years. Projected system demands were added for the 2017 and 2031 planning years. The model was used to evaluate both typical system conditions during diurnal operations, as well fire flow availability. February 14, 2012 - DRAFT 7-24 pw-f/CarollolDocument DientM'Alkenton78595A00/Deliverables/Chapter Mh07.docx 7.5.1 Evaluation Criteria System policies and criteria were discussed in detail in Chapter 5. The key parameters evaluated with the model were for the system pressure criteria during normal operations and fire flow testing of the system. During normal operations, the minimum pressure as set by DOH and ISO standards during MDD and peak hour demand (PHD) is 30 pounds per square inch (psi) at the service meter. The City's goal is to provide a maximum of 110 psi at the service meter. Building code requires the installation of individual Pressure Reducing Valves (PRVs) when the meter pressure exceeds 80 psi. 7.5.1.1 Fire Test Model Criteria The fire flow demand and duration requirements for different sized fires are summarized in Table 7.22. During any fire, the minimum pressure within the service area should be greater than 20 psi at the end of the fire_ In general, areas zoned residential should have 1,000 gpm available, and areas zoned commercial should have 3,000 gpm available. Figure 7.4 shows the minimum fire flow required at nodes throughout the system based on land use. Table 7.22 Service Criteria for Required Fire Flow Land Use Required Flow (gpm) Required Duration (hours) Single family (< 3,600 sq ft) 1,000 1 Single family (> 3,600 sq ft) 1,500 2 Multifamily and Commercial/industrial 3,000 3 Multifamily and Commercial/industrial 4,000 4 Multifamily and Commercial/industrial 5,000 — 6,000 4 Beyond the general fire requirements, some locations have higher fire requirements as specified by the City's Fire Marshal. The largest of these fires for each zone are summarized in Table 7.23, and the locations are shown in Figure 7.5. The points are numbered in the format xxx-y, noting the zone (xxx) and a sequential number (y).

This approach allows the sources, pumps, and tanks to all operate as their SCADA is set. For the runs, the model makes up any water shortage from EW -3 and the SPU Bow Lake Pipeline. Figures 7.6 and 7.7 show the nodes with pressures outside of the planning criteria in 2017 and 2031, respectively. As seen in the figures, many nodes are outside of the target pressure range in 2017. Some additional deficiencies exist in 2031. Of the low-pressure nodes (below 30 psi), some exist adjacent to the Springbrook transmission line. The City has been working to remove connections to this line and onto the adjacent higher pressure line. The model results had other low-pressure nodes near reservoirs, these nodes were excluded in the evaluation as service connections do not exist according to City staff. As seen in Figures 7.6 and 7.7, many high pressures exist in the system_ The majority of the Kennydale 320 Zone has very high pressure. Some of the pressure zones cover large elevation ranges, leading to very high pressures at the lower elevations. In addition, the booster pumps commonly discharge into the pressure zones near the bottom of a hill, forcing flow to the tank through the distribution system. This requires the hydraulic grade line (HGL) at the bottom of the hill to be higher than the tank overflow level at the top of the hill. In turn, this boosts the pressure in the lower elevations even higher during pumping than under static conditions based on tank overflow and meter elevation. 7.5.3 Fire Flow Analysis The model was used to test the fire capabilities at the 28 large fire locations, using the fire flow test feature. All of the system nodes with service connections were tested for a minimum pressure of 20 psi during the point fire demands. Table 7.24 summarizes the available fire flow at these locations in both 2017 and 2031. All of the locations have adequate fire flow available, with the exception of two locations in the Kennydale 320 Zone. This zone includes a high -elevation service connection at Lincoln Ave and NE 36th, causing difficulty in maintaining 20 psi during a fire elsewhere in the system. The model was also used for a general fire analysis at 1,000 gpm and 3,000 gpm, testing all of the system nodes with service connections for 20 psi in both 2017 and 2031. Figures 7.8, 7.9, 7.10, and 7.11 show the available fire flows throughout the system_ The majority of the Valley Service area is slightly deficient, due to the low-pressure nodes along the Springbrook transmission line. There are limited deficiencies throughout the system, primarily at the ends of smaller dead end lines, and in areas of older 4- and 6 -inch piping networks.

The City has been moving low-pressure service connections along the Springbrook transmission line from the Valley Pressure zone to the Talbot Hill 350 and 270 pressure zones. The remaining low-pressure service connections need to be moved to improve meter delivery pressure and increase fire flow capabilities. Several areas in the system exceed the maximum pressure criterion_ The Kennydale 320, Rolling Hills 590, Rolling Hills 490, Highlands 560, Highlands 435, Talbot Hill 350, West Hill 495, West Hill 300, and Earlington 370 all experience high pressures. In general, it is recommended that pressures be kept to a minimum to reduce pipe losses due to over - pressurization. Rezoning or creating additional pressure zones is recommended to reduce the system operating pressures, thereby reducing the need for individual service connection PRVs, reducing potential leakage, and reducing the range of elevations served by each zone. Several areas were reviewed for potential rezoning or zone creation, as presented in Figures 7.12 through 7.26. Figure 7.12 presents a legend of the areas reviewed associated with the pressure deficiencies found in the year 2031. The figures show potential improvements, such as locations of new PRVs, closed valves, or extending pump discharge piping to higher elevations. For each of these areas, it is recommended that the City perform a Rezone Study to determine how to best redistribute operating pressures and confirm the required system modifications. The following Rezone Studies are recommended: Kennydale 3201 Highlands 435 Rezone Study. 2. Rolling Hills Rezone Study. 3. Talbot Hill 350 Rezone Study. 4. West Hills Rezone Study. Two specific areas are discussed below. Kenn dale 320 Zone As shown on Figure 7.14, it is recommended that the Kennydale 320 Zone be rezoned to match the Valley 196 Pressure Zone. Higher elevation connections, such as near Lincoln Ave and NE 36th, should be served by the Highlands 435 Zone. This modification reduces pressures in the Kennydale 320 Zone, and also improves the ability to maintain 20 psi during February 14, 2012 - DRAFT 7-39 pw:I/Carollo/DocumentslGientMAlRenton78595A001DeliverablWChapler 71ChOTdou a fire flow in the lower zone. As the majority of the pressure zone is higher than 110 psi in the future, a rezone will be needed to meet the fire demand. West Hill 300 Zone The West Hill 340 Zone future fire flow capabilities are limited by a high -elevation service connection on a dead-end pipe on South 132nd Street. These high -elevation nodes should be reconnected to the West Hill 495 Zone by extending a pipe to them. These nodes will be connected to an area of high pressure, therefore a new pressure zone should be considered for this area.

The condition assessment focused on identifying the remaining useful life (RUL) of the City's water pipes. The length of time that a pipe is anticipated to remain functional is called the useful life. Useful life depends largely on the pipe material, but can also depend on soil conditions, water constituents, and installation_ When a pipe is in service beyond its useful life, the increasing costs of maintenance associated with a failing pipe typically warrant replacement.

Table 7.26 Useful Life of Pipes Pipe Material Original Useful Life Assumption (yrs) Asbestos Cement (AC) 70 Cast Iron Pipe (CIP) 60 Ductile Iron Pipe (DIP) 80 Galvanized Steel Pipe (Gals) 50 High Density Polyurethane Pipe (HDPE) 70 Polyvinyl -Chloride Pipe (PVC) 80 Steel Pipe (Steel) 70 RUL is defined as the length of time left before a pipe will reach the end of its useful life. Pipe age and material type were used to determine the RUL of the City's pipes. The City's GIS data was used to determine the type of material and year that pipe segments were installed. Table 7.27 presents the total length of pipe according to the year installed and material type. As seen in the table, the majority of the City's pipes are Cast Iron Pipe (CIP), installed from 1920 to 1980, and Ductile Iron Pipe, installed from the 1970's to today. The cells of Table 7.27 are color -coded to show the RUL of pipes in that category. For example, the lengths of pipe in the red cells have all reached the end of their useful life (have a remaining useful life of zero). Using these assumptions, approximately 132,000 linear feet (LF) of pipe, or 8 percent, of the City's pipes have an RUL of 10 years or less. From the data, approximately 24 percent of the City's pipes are expected to reach the end of their useful life in the next 20 years. Figure 7.18 presents the total length of pipe reaching the end of its assumed useful life by year. All pipes that have already exceeded their useful life are shown in the year 2011. Given a maximum useful life of 80 years for any pipe type, pipes installed today are expected to require replacement in 2091. The figure also presents the annual replacement per year for two scenarios. If the City wishes to start annual replacement of all its pipes from 2011 until 2091, approximately 20,000 LF of pipe would need to be replaced annually. This is shown as a green line on the figure. From the figure, it is apparent that many pipes are expected to reach the end of their useful life by the year 2045. To maintain replacement schedules just until the year 2045, approximately 14,000 LF of pipe would need to be replaced annually. This is shown as a red line on the figure_ It is recommended that the City begin an annual pipe replacement program of 14,000 LF per year targeting the pipes that have reached the end of their useful life, and to offset the depreciation of this City asset. Figure 7.19 presents the locations of these pipes.

Projects to address deficiencies found in the year 2017 are of higher priority than those to address deficiencies in the year 2031. 7.6.1 2017 Improvements Pump Station Improvements: Install back-up power generators at the West Hills BPS. Storage Improvements: • Construct a new 1.0 -MG tank for the Valley Operational Area to improve the ability to serve the highest customers during an emergency. This project could be delayed if the City enters negotiations with SPU for additional supply to this zone. • Alternatively, the City could rezone the Valley 196 Zone to eliminate the high -elevation customers. • Install back-up power generators at the Monroe Avenue BPS to allow storage to be provided from the Highlands 435 Zone to the Highlands 565 Zone (will also improve pumping capacity for long-term). • Add back-up power to the Maplewood BPS to increase pumping capacity from the Rolling Hills 490 Zone to the Rolling Hills 590 Zone. • Add auto -start, auto -transfer, and back-up power to the Rolling Hills BPS such that three pumps can be operated at the same time. • Add auto -start, auto -transfer back-up power to South Talbot BPS to increase pumping capacity and reduce the storage deficit. Pipeline Improvements: Complete approximately 18,000 LF of pipeline improvements presented in Table 7.25 to address 2017 fire flow deficiencies. Implement a new Annual Pipeline Improvement Program to address pipes that have reached the end of their useful life_ Approximately 14,000 LF of pipeline must be replaced per year as part of this program. It is recommended that this program be completed concurrent with an Asset Management Program.

The operations and maintenance staff is shown under the Maintenance Services Division within the overall organization of the water system. Descriptions of individual job functions and responsibilities as they relate to specific operations and maintenance activities are described below. 8.1.1 Normal Day -to -Day Operations Normal day-to-day operations of the water utility are the responsibility of the Water Maintenance Services Section under the direction of the Water Maintenance Services Manager, Mr. Ray Sled. The Water Maintenance Services Unit is under the direction of Mr. George Stahl_ The Water Maintenance Services Unit is responsible for main flushing; tank and reservoir cleaning; exercising valves and hydrants; leak detection and repair; PRV maintenance and setting; small meter maintenance, repair and calibration; hydrant maintenance and repair, and tie-in of water main extensions. The Water Utility Maintenance Unit is under the direction of Mr_ Craig Pray. The Water Utility Maintenance Unit is responsible for the operation, maintenance, and repair of the booster pump stations; wells; treatment systems; treatment plant; supervisory control and data acquisition (SCADA) system, and water quality sampling for operations and regulatory compliance. 8.1.2 Preventive Maintenance Preventive maintenance is performed by both the Water Maintenance Services Section and by contract to private parties. For example, large meter maintenance and calibration is contracted out, whereas painting of components of a booster pump station is usually performed by Water Maintenance Services Section personnel. Large maintenance projects, for example water tank painting, is done by public works contract with contractors selected under public bidding rules. These projects are usually managed by the Water Utility Engineering Section. 8.1.3 Field Engineering Field engineering support is supplied by the Water Utility Engineering Section. In some cases the engineering support is provided by City Staff and in other cases the support comes from engineering consultant firms. The City periodically selects a group of consulting firms that are pre -approved to complete small engineering jobs on a short notice (consultant roster). February 16, 2012 - DRAFT 8-1 pw:liCaroilolDocumentslClienUWAIRentorl8595ADOIDeliverableslChapler MhO8.dou 8.1.4 Water Quality Monitoring Water Quality monitoring is primarily conducted by the Water Utility Maintenance Unit (Unit). The Unit performs both operational and compliance water quality monitoring. Operational water quality monitoring includes: chlorine, fluoride, turbidity, temperature, polyphosphate, iron, manganese, ammonia, hydrogen sulfide, pH, well water level, and well production rates_ Compliance water quality monitoring is required by the Federal Safe Drinking Water Act of which most requirements are administered by the Washington State Department of Health and are published in WAC -246-290. Compliance monitoring includes: volatile organic chemical, synthetic organic chemical, trihaiomethanes and Haloacetic Acids, inorganic chemical and physical, bacteriological, radionuclides and tap sampling for lead and copper. The City maintains a system of monitoring wells around its production wells for the purpose of detecting contamination of the aquifers before the contaminants reach the productions wells. The Water Utility Engineering Section conducts this monitoring. The Water Utility Engineering Section also monitors the water table levels in the aquifers. All of the test results of compliance monitoring, with the exception of coliform monitoring sampling and monthly fluoride meter calibration check sampling, are stored in the City's enterprise -wide database. The results of monitoring for aquifer contamination are stored in the City's enterprise -wide database. Water level data collected by portable sounder is stored in the City's enterprise -wide database. Water level and water temperature data collected by automated sounder is stored on one of the City's network servers. 8.1.5 Emergency Response The City of Renton Emergency Response Plan defines how the City will respond to emergencies. This plan is maintained by the City of Renton Emergency Management Director with the City of Renton Fire and Emergency Services Department. The Water System Emergency Response Plan is a sub -plan to the City of Renton Emergency Response Plan. The Water System Emergency Response Plan includes information on security and terrorism threat and response. The Water Maintenance Services Manager is responsible for preparing for and responding to emergencies involving the drinking water system. The Water Maintenance Services Section maintains an emergency call-up list for employees on standby to respond to emergencies after hours on weekdays, on weekends and on holidays_ The response to an emergency may vary from a single maintenance technician addressing a relatively minor problem to the City activating the Emergency Operations Center and calling on the state or federal government to lead the response in a large disaster or terrorism incident_ 8.1.6 Cross Connection Control Plan The Cross Connection Control Plan is included in Appendix G of this Water System Plan. Most potential cross connections are identified through the plan review and building permit February 16, 2012 - DRAFT 8-2 pw,llCarolloA7ocumentslClientfWA/Renton/8595A007QeliverableslChapter 8008,doex review process. The Water Utility Engineering Section and the Development Engineering Section work together to identify potential cross connections during the plan review process for proposed development projects. Cross connections that are identified are eliminated or are controlled by the installation of backflow prevention assemblies. The cross connection control specialist in the Water Utility Engineering Section works with the building inspectors in the Development Engineering Section to ensure that cross connections which are discovered during inspections are either eliminated or controlled by the installation of approved backflow prevention assemblies. The Cross Connection Control Specialist maintains records on the City's enterprise -wide database of installed backflow prevention assemblies including installation and test history, and information on the cross connection which they secure. The database is also used to generate test notices to send to the owners of the backflow prevention assemblies. The City uses XC2 Software LLC's, XC2 software, to input information, query information, and generate reports, including test notices from the database. Members of the Water Maintenance Services Section, Water Utility Engineering Section, Development Engineering Section and Building Section are always on the alert to discover cross connections as they go about their duties throughout the City and its built environment. If cross connections are discovered they are reported to the City's Cross Connection Control Specialist_ 8.1.7 Capital Improvement Program Implementation of the Water Utility's capital improvement program is primarily the responsibility of the Water Utility Engineering Supervisor. Most of the improvements are done by public bid contracts. The Water Utility Engineering Supervisor works closely with the Water Maintenance Services Manager to identify and prioritize capital improvements. See Chapter 9, Capital Improvement Program, for more information. 8.1.8 Budget Formulation The Water Utility Engineering Supervisor formulates the Water Utility capital improvement program budget and the Water Maintenance Services Manger formulates the operations and maintenance budget. Both work closely with their Division Directors and the Public Works Department, Principal Financial and Administrative Analyst, to formulate their budgets. The Principal Financial and Administrative Analyst works with Finance Division staff to formulate the complete Water Utility budget. 8.1.9 Response to Complaints Complaints and questions are fielded by members of both the Water Utility Engineering Section and Water Maintenance Services staff. All water quality complaints are forwarded to the Maintenance Services Division secretary (426430-7400) for logging, response and tracking and follow up by the Water Maintenance Services Section. February 16, 2012 - DRAFT 8-3 pw:llCarcllolDocumentslClientlWAlRenionl6595AOO1DeliverableslChapter KhOB.dom 8.1.1 D Public and Press Contact Contact with the media is handled by the City of Renton Communications Director or his/her representative. The Development Services Division mans a customer service counter on the sixth floor of Renton City Hall. Members of the Water Utility Engineering section often report to the customer service counter to assist customers with questions about water quality and water service availability. 8.1.11 Billing Billing for the Drinking Water Utility, as well as for the wastewater, storm, and solid waste utilities, is performed by the Fiscal Services Division of the Finance and Information Technology Department. The water meter readers work under the Water Maintenance Services Manager. Billing problems are referred to Utility Billing staff in the Finance and Information Technology Department. 8.2 OPERATOR CERTIFICATION The City of Renton's drinking water system is classified as a Group 4 distribution system because the system serves a population of greater than 50,000. The Maplewood Water Treatment Plant treats water to remove iron and manganese using green sand filtration; converts hydrogen sulfide to sulfate through the addition of oxygen in conjunction with catalytic conversion on granular activated carbon, and removes ammonia by reacting it with chlorine to convert it to nitrogen gas. Additionally, the water is treated with fluoride. The plant is considered a Class III purification plant (Association of Boards of Certifications classification). Water pumped by wells RW -1, RW -2, and RW -3 receives primary disinfection by flowing through a pipeline designed to provide a chlorine contact time of six minutes (CT6) at the maximum flow rate. Additionally the water is treated with fluoride and sodium hydroxide. This plant is considered a Class 1 purification plant. Other treatment in the system includes in-line fluoridation, in-line chlorination, and the addition of sodium hydroxide and ortho polyphosphate to inhibit the internal corrosion of water mains and private plumbing. These treatment systems are not considered purification plants. Per the requirements of WAC 246-292, Renton's water system must be managed by a Water Distribution Manager IV; the Maplewood Treatment Plant must be operated by a Water Treatment Plant Operator III or higher; Wells RW -1, RW -2, and RW -3 must be operated by a Basic Treatment Operator or higher, and the Cross Connection Control Program must be managed by a Cross Connection Control Specialist. The City meets or exceeds all of these requirements. Table 8.1 lists the certifications of the drinking water staff. In-service training consists of special courses and seminars specifically designed for operation and maintenance groups. The training is offered through organizations like the American Water Works Association, Pacific Northwest Section; Evergreen Rule Water February 16, 2012 - DRAFT 8-4 pw:IfCarollo/DocumentslClienONNRentonlBS95A0010efiverableslChapter 8008.dou Association; Washington Environmental Training Center; equipment vendors; local colleges and universities, and trade organizations. Renton supports and promotes operator training. As the complexity of the Renton's water system increases, the need for trained and efficient staff to keep pace with advances in technology and ever-expanding federal and state regulation will become more important. New employees need utility orientation and basic information and experienced employees need training in regulatory requirements and technological updates. The importance of regular employee training can be strengthened by linking the training with the personnel evaluation program. The personnel evaluation program should be used to provide the employee with a regular and predictable employee promotion plan. A predictable employee promotion plan that is closely linked with an employee -training program can improve employee competency and proficiency. Mandatory certification, as well as the qualifications and training requirements for obtaining and maintaining the certification, is stipulated by the State of Washington. The City Council and City Administration have endorsed the idea of increased and continuous training.

Additionally, the Water Maintenance Services Section has written procedures for both electrical and hydraulic lock-out/tag-out of the water system facilities_ All sources and booster pump stations are metered and all flow is monitored and recorded by the SCADA system. The flow through the metered connections to the Seattle Public Utilities pipelines at the Fred Nelson Booster Pump Station, Tiffany Park Booster Pump Station and Bow Lake Pipeline is monitored and recorded by SCADA. In addition to the information recorded by SCADA, Water Maintenance Services staff read and record meter readings at all sources and all pump stations, daily if the facility is in operation and twice per week if the facility is on standby. Retail meters at customer connections are read either monthly or bi-monthly. The meter reading routes, sequencing, and cycles are maintained in the City's Utility Billing System. Meters are read either visually, with touch read wands, or by radio read. Currently the City has United Pipe and Supply, Inc., under contract to install an Automated Meter Reading System (AMR). The first AMR ready radios will replace the existing radios on meter reading February 16, 2012 - DRAFT 8-6 pw:tlCarellalDocuments/ClientANNRenton/8595ADO/Deliverables/Chapter KhD8.docx routes 25 and 31. The first AMR ready radios are scheduled to be installed in October 2011. Initial testing of the AMR system will begin shortly thereafter. The system performance is evaluated in terms of meeting federal and state drinking water quality requirements; maintaining customer satisfaction; controlling the cost of production and delivery of water, and meeting system policy goals for service pressure and fire flow. 8.3.3 Preventive Maintenance Program The preventive maintenance program is documented and tracked by Infor EAM (Enterprise Asset Management). Infor EAM is a computer-based system that is used to schedule preventive maintenance and assign resources where they will do the most good; predict equipment reliability problems and prevent them from happening, and manage assets to best meet the organization's goals. 8.3.4 Equipment, Supplies, and Chemical Listing Table 8.3 is a listing of vehicles and major equipment assigned to the Water Shop. Inventoried supplies (items stocked on shelves or stored in the yard) are purchased and tracked by the Maintenance Services Division Maintenance Buyer and staff. The Water Maintenance Services Manager and staff provide input to the Maintenance Buyer as to appropriate items and quantities to stock_ In addition to stocked items the Maintenance Buyer maintains information on source of supply for chemicals that are delivered directly to the place of use and for parts and equipment items that are not stocked on the shelf or in the yard due to low frequency of purchase or large physical size. The Maintenance Buyer uses the Infor EAM system to purchase items and manage inventories. The Water Maintenance Services Manager maintains information regarding service representatives for major water system components and chemical suppliers_ Additionally, the Water System Emergency Response Plan contains lists of contacts for suppliers and support services. Both the Water Maintenance Services Section and the Water Utility Engineering Section maintain copies of the O & M manuals for all of the major components of the drinking water system. These manuals list manufacturer part numbers and descriptions as well as technical specifications for components and chemicals used. 8.4 EMERGENCY RESPONSE PROGRAM The Drinking Water Utility maintains a Wafer System Emergency Response Plan, which is a sub plan to the City of Renton Emergency Response Plan. 8.4.1 Water System Personnel Emergency Call-up List The Water Maintenance Services Section publishes two emergency call-up lists: one for emergencies dealing with wells and booster pump stations and one for emergencies February 16, 2012 - DRAFT 8-7 pw:llCarallolDocumenis/CIIenVWAlRentonf8595ADOiCeliverables7Chapter Kh48 docx dealing with water mains, PRV stations, and water tanks (reservoirs). The SCADA system is connected to an auto dialer that is used to contact call up personnel when an alarm is triggered after office hours. The auto dialer is programmed to move down a list of phone numbers until its call is acknowledged_ After office hours calls to 911 that are water system related are handled by the 911 dispatch who then contacts a cell phone that is carried by on call staff. If the on-call staff does not answer the cell phone the dispatcher will attempt to contact the Water Maintenance Services Manager, the Water Maintenance Services Supervisor or the Water Utility Maintenance Supervisor. Other phone numbers are available to the dispatcher including the Maintenance Services Director's cell phone number. 8.4.2 Notification Procedures - Water Quality Emergencies See Appendix H, Drinking Water Quality Monitoring Program. 8.4.3 Vulnerability Analysis See Chapter 5, Policies, Criteria, and Standards, for the Water Utility's reliability and vulnerability policies. The Water Utility completed a security vulnerability assessment in December 2003 and updated the city-wide Emergency Response Pian in June 2004 as required by the Public Health Security and Bicterrorism Preparedness and Response Act of 2002. The Water Utility budgets for security improvements in its Water System Capital Improvement Program. Typically this money is transferred into specific project budgets were security upgrades are incorporated into the overall project scope. Periodically, the Water Utility assesses the vulnerability of its drinking water system to threats from earthquakes, floods, power outages, etc. New facilities are designed and constructed to the latest building code standards. In addition, extra emphasis is placed on hazard engineering when the new facilities are critical to the operation of the water system. Retrofits of existing facilities typically incorporate security and safety upgrades and sometimes structural modifications to enhance survivability and operability of the facility after natural or manmade disasters. The Water Utility designs and constructs redundancy in its water main network, supply sources, pressure zone transfer pumps and PRV stations, etc., to increase the system's overall reliability and reduce its vulnerability to disruptions. 8.4.4 Contingency Operational Plan Contingency operational plans for the various facilities are included in the, Water System Emergency Response Plan.

Each call is logged into the Infor EAM system. When applicable, a staff member is assigned to the complaint. Infor EAM tracks the problem; its location; who is assigned to investigate/fix the problem; what was discovered in the field; what was done to address the complaint, and how much time/materials were expended. Complaints are mainly regarding water leaks (80%) and taste and odor problems (20%). 8.7 RECORD KEEPING AND REPORTING Maintenance and operating records are an essential tool in utility management and operation. They also provide the supporting data necessary for long-term planning. The Water Utility keeps several types of records: water quality sampling for operations and mandatary water quality sampling records (see Appendix H); chemical dosing records; water main disinfection records; hydrant flushing records; source production, and booster pump station pumping records; reservoir level records; aquifer level records; personnel records; customer contact records; meter records; inventory records, etc. The City's records are legible, permanent, accurate, and accessible. Their importance to the efficient functioning of the Utility is effectively addressed in the context of the in-service staff training sessions. Hard copies of the records are maintained at the Water Maintenance Services Manager's office. The Water Utility Engineering Section maintains information on mandatory water quality sampling test results in a database in the City's enterprise database management system. The Water Utility Engineering Section also maintains electronic copies (MS Excel files) of the Water Maintenance Services Section's operational records on one of the City's network servers. The Water Utility Engineering Section maintains records of backflow assembly test results, tester certifications, test notifications, backflow assembly information and cross connection information in a database in the City's enterprise database management system. February 16, 2012 - DRAFT 8-9 pw,liCarollolDocumentslClientWAlRenlon18595AOOIDeliverableslChapter tl1Ch0$.docx The SCADA system (described in Chapter 2) records the flow rates and flow quantities of all wells, booster pumps, and spring; water levels in reservoirs and production wells; levels in chemical storage tanks; pH levels of raw and treated water; pump starts and fails; alarm conditions; and various other data. Current maps of the water system are also important for operation and maintenance. Changes or additions to the water system are added as they occur by the Water Utility Engineering Section and paper and electronic copies are provided to the Water Maintenance Services Section, the Fire Department, Development Services Division, and others. The geospatial and attribute information on the drinking water system is maintained in ESRI ArcGIS (ArcSDE geodatabase in the City's enterprise database management system). Currently the Water Maintenance Services Section maintains five laptop or tablet PCs which are loaded with the ArcMap. The laptops and tablet PCs are updated periodically with the most current GIS information. The GIS information is viewed using ArcView. The laptops and tablet PCs are used by the utility locators, valve crews, and meter technicians. For users at City Hall, the Water system information is available through an ArcGIS Server, web based application. Paper forms of the maps including valve, hydrant, and fire flow map books at 1" = 400" scale and wall maps at various scales are available upon request. Maps are also available in PDF format.

The improvements are needed to correct existing system deficiencies to keep the system running in order to reliably supply the City's water customers with safe, clean water that meets federal and state drinking water regulatory requirements. The Capital Improvement Plan (CIP) also outlines planned projects that are needed to upgrade and expand the City's water system to meet future water demand from growth in population and from development within the City of Renton water service area. 9.2 CAPITAL PROJECTS The City has a separate Capital Improvement Plan (CIP) document that prioritizes projects and identifies funding plans for a 6 -year period. The CIP document is updated and adopted bi-annually as part of the Council's adoption of the City's operating budget. Capital projects are generally categorized into water supply, water quality and treatment, storage facilities, pump stations, water main rehabilitation and replacement, major maintenance, and regulatory compliance programs. The City maintains a current inventory of its water system infrastructure and assets through a Geographic Information System (GIS) based FSRI ArcGIS 11.0. The City is working on the development of a comprehensive Asset Management Program (AMP) to manage the life cycle of all of its water system assets in the most cost effective, sustainable manner to meet established service level goals. The overall water infrastructure capital improvement program will be re-evaluated based on the findings and recommendations of the final Asset Management Plan. 9.2.1 Projects to Address Future Water Supply Needs and Increase Storage Capacity 9.2.1.1 50 -Year Water Supply Purveyor Contract with Seattle Public Utilities In 2011, the City of Renton entered into a 50 -year (2012-2062) water supply contract with Seattle Public Utilities (SPU) for the purchase of additional water to supplement the City's own supply sources in order to meet peak day water demands and future water demands from population and development growth within the City's retail water service area. The wholesale contract with SPU also allows for additional system intertie connections to SPU's Cedar River Pipelines, Bow Lake Pipeline, and Fast Side Supply Line, when needed; there is no limit on the quantity of water that the City can purchase from SPU. The City has February 16, 2012 - DRAFT 9-1 pwllCarollo7Documents/01ientPNA/Renton18595AOO/DeliverahleslChapter MhO9,dou constructed necessary upgrades to its existing interties with SPU, including the installation of flow control valves and meters and connection to the SCADA telemetry system to monitor water purchased from SPU. 9.2.1.2 Future Reservoirs to Increase Storaae and for Operational Flexibili The City will be able to meet its future storage requirements by adding new reservoirs and by replacing existing reservoirs as described below. Although, the storage analysis in Chapter 7 shows various estimated deficits in storage in certain pressure zones in future years, the City plans to install larger reservoirs in the future by maximizing their footprints within the current City -owned properties. The larger reservoirs will also provide operational flexibility and added reliability and redundancy of system capacity, in case there is a need for the City to take an existing reservoir out of service for maintenance. Proposed reservoir sizes will be confirmed during pre -design of these projects. The City is also planning to install emergency and back-up power to its remaining well pumps and booster pump stations including automatic transfer switches to reduce the standby storage volume requirements. 9.2.1.2.1 Blackriver Reservoir— Valley 996 Zone This project consists of property acquisition, planning, design, construction of a new reservoir in the 196 pressure -zone to provide additional storage along with operational flexibility and reliability.

The estimated cost for this project is $16.4 million. 9.2.4 Transmission and Distribution Pipelines Renewal and Replacement Projects These projects consist of the planning, design and construction for the systematic replacement or renewal of old transmission mains and of old, undersized and leaky steel, cast-iron, and asbestos -cement distribution mains throughout the City, to restore or increase fire flow capacity and to improve water quality. Prioritization of the pipe replacement program is based on several factors including degree of fire flow deficiency, number of past leaks and breaks found and repaired and likelihood and frequency of future leaks and breaks, predicted residual life of the pipe, number of water quality complaints and results of investigations, and coordination with other scheduled City roadway and utilities improvements projects. The City's pipeline renewal and replacement program and overall water infrastructure capital improvement program will be re-evaluated based on the findings and recommendations of the final Asset Management Plan. 9.2.4.1 Asset Management Plan for Renewal and Replacement of Water Mains This project consists of a phased development of a Water Utility Asset Management Plan (AMP) in order for the City to better manage the life cycle of its water system assets in the most cost effective, sustainable manner to meet established levels of water service delivery to our customers. The AMP will be structured around the Ten Core Processes introduced and promoted by the USEPA. The first phase of the AMP project will focus on the City's water distribution pipes which is the largest asset class in the water system. 9.2.4.2 Water Main Replacement Protects to Increase Fire Flow Capacity In order to provide the current minimum fire flow of 1,000 gpm in single-family residential areas, the City plans on replacing the existing and undersized water mains in old residential subdivisions with larger ductile pipes, with an 8 -inch minimum diameter. Looping of the mains will be provided, and dead-end mains will be eliminated when possible, to increase flow capacity and to provide system reliability. Old and substandard hydrants will be replaced with new ones, and additional hydrants will be installed to meet current fire codes for the spacing of hydrants. Priority will be given to old 4 -inch, 6 -inch, and dead-end lines and for pipes located in streets that are planned for reconstruction including asphalt overlays. February 16, 2012 - DRAFT 9-6 pw:/?Camlla/DocumertWClienWYA)Rentonf8595ADODeliverables/Chapter Kha9.docx 9.2.4.3 Annual Water Main Replacement Program This program consists of the systematic replacement of old water mains that have reached their anticipated remaining useful life. A summary of the estimated remaining useful life of various types of pipe materials and the ages of the pipes is shown in Chapter 7. This program will be further refined and implemented based on the findings and recommendations of the City's Asset Management Plan, which is anticipated for completion in 2012-2013. The annual budget for the City's pipe replacement is $1 million_ 9.2.4.4 Optimization of Pressure Zones in Distribution System As part of the hydraulic analysis of the City's water system described in Chapter 7, deficiencies found in the distribution system will be evaluated and corrected as part of this on-going capital improvement program. For areas where the hydraulic analysis shows that the water pressure in the distribution system exceeds 110 psi under normal system operation, the City will do a study to convert the existing zone to a lower zone, as discussed below. For areas where the hydraulic analysis shows that the water pressure in the distribution system during a fire condition event is less than 30 psi, which is the City's desired level of service for minimum pressure at the customers' meters, the City will do a study to convert the existing zone to a higher zone, as discussed below. Figures 7.12 through 7.26 in Chapter 7 show potential improvements, such as locations of new PRVs, closed valves, or extending pump discharge piping to higher elevations. For each of these areas, it is recommended that the City perform a Rezone Study to determine how to best redistribute operating pressures and confirm the required system modifications. The following Rezone Studies are recommended: • Kennydale 3201 Highlands 435 Rezone Study. • Rolling Hills Rezone Study. • Talbot Hill 350 Rezone Study. • West Hills Rezone Study. The estimated cost of this program will be developed as part of the evaluation and study for each project. 9.2.4.5 Water Main Replacement in congunction with Roadway Improvements Proiects This program consists of the replacement of existing water mains in conjunction with the construction of major roadways and utilities improvement projects to reduce the cost of future replacement of the lines and to minimize construction impact to traffic, businesses, and neighborhoods within the various project areas.

Grady Way to S. 2nd St This project consists of the replacement of existing water mains in Rainier Avenue from SW Grady Way to S 2nd Street, in conjunction with the City's Transportation Department's roadway improvements project. The new 12 -inch water mains will improve the fire flow capacity for the existing commercial businesses and for future development and redevelopment projects within the Rainer Avenue corridor. The estimated cost for this project is $1.5 Million. 9.2.4.7 SW 27th St - Strander Boulevard Water Main Extension This project consists of the extension of a 12 -inch water main in Strander Blvd west of Naches Ave SW in conjunction with the City's transportation roadway improvements project. The new water main will provide water service to the abutting private commercial properties owned by the Boeing Company. The estimated cost for this project is $130,000. 9.2.4.8 Water Main Improvements in Redevelopment Areas Redevelopment activities can have a substantial impact on the ability of the existing distribution system to provide sufficient water to customers for fire protection service and for domestic uses. Typically, detailed hydraulic models are used in conjunction with area water demand forecasts and fire flow requirements to identify potential water main improvements in redevelopment areas. Water main improvements needed for redevelopment projects are typically installed and paid for by the developers. The developers may recoup some of their costs from future benefitting properties by applying to City Council for a latecomer agreement. In some cases, with the approval of funding from the City Council, the City may install the improvements or participate in the cost of the improvements with the developers and the City recovers its costs from benefitting properties through a Special Assessment District. The pipe replacement program for redevelopment projects is designed to balance the City's investments in pipe replacement projects to reduce risks associated with aging pipe infrastructure with investments in major pipe replacement projects to support growth and development. 9.2.4.9 Other On -Going Capital Programs and Plans 9.2.4.9.1 Reservoirs Recoat This project consists of a scheduled recoating of the interior and exterior surfaces of the existing steel stand pipe and elevated reservoirs to extend the useful life of the structures. The installation of safety upgrades and of a cathodic protection system is included in this project. The budget for this program is $100,000 per year.

The Water Utility operates as an enterprise fund and as such, it must be self-sustaining. Water utility funds are accounted for and budgeted separately, but are managed as a system with other City enterprise funds in accordance with the City's financial management policies. These polices are described in more detail in Chapter 5, and include the following: • Fiscal Stewardship. • Self-sufficient Funding. • Rate Stabilization. • Operating Reserve. • Debt Service. • Bonds vs. Cash Expenditures. • Comprehensive Planning. • Equitable Rates. 10.2 REVENUES AND FUNDING SOURCES The City accounts for its water revenues and other funding sources in two main separate funds: Fund 405 — Fund 405 is the Operating Fund for the City's water utility_ It was created in 2006 for the purpose of identifying water utility revenues and expenses. Revenue sources for this fund are generally from water sales and collections, but also include revenues from plan review and inspection fees, water meter installation fees, utility billing fees, rent and leases, and inter -fund reimbursements from other City's departments for services provided. Expenses include Operation and Maintenance (O&M), debt service payments for Public Works Trust Fund (PWTF) loans, revenue bonds, taxes, and transfers to the Construction Fund. Fund 425 — Fund 425 is the Construction Fund for the Water Utility for the design, construction, and project management of capital improvement projects. Revenues from this fund include transfers from the Operating Fund, utility collection fees, special assessment fees, system development charges, water connection charges, City February 10, 2012 - DRAFT 10-1 px:11CamlidDacumentstClienYW)VRenton18595A001DeliverableslChapter 101CM doc issued bonds, proceeds from revenue bonds, proceeds from PWTF loans, and from Community, Trade, and Economic Development grants. The Finance Department maintains the financial records for the Water Utility and both the Finance Department and the Public Works Department monitor and evaluate the Utility's fiscal performance. 10.3 HISTORICAL FINANCIAL PERFORMANCE Table 10.1 summarizes actual cash -basis revenues, expenses, and fund balances for the Water Utility Operating Fund 405 for the 5 -year period 2006-2010. Over this 5 -year period, the Utility fund balance, which represents total unexpended resources carried forward to future years, increased from $3.9 million to $4.7 million. A total of $13.8 million was transferred over the period to the Utility Capital improvement Fund to finance budgeted capital project expenses. These transfers represent 24 percent of total water utility expenses and 30 percent of the water service collection revenues for the 5 -year period. As of December 31, 2010, included in the ending fund balance are the Operating Fund reserves of $725,242 and Debt Reserves of $1,955,020, per the City's financial policies.

This type of forecast is February 10, 2012 - DRAFT 10-3 pw:11CarollaUcumentslClienYWAIRentanl8595Aa01aeliverables/Chapter 1TCHD.doc routinely used by utility staff to develop rate adjustment proposals and to assess the impact of changing budget assumptions on future rate requirements. Some key assumptions used to forecast future annual revenues and expenses that appear in Table 10.2 include: Growth in total water utility customers/water consumption levels will equal 0.3 percent per year for the years 2011 through 2012, 0.4 percent per year for the years 2013 through 2015, and 0.5 percent for the years 2016 through 2020. 2. Wholesale water sales to Skyway Water & Sewer District are not anticipated to increase, since Skyway obtains most of its water through a water supply contract with Cascade Water Alliance and through its independent sources. 3. Interest and other revenue sources are anticipated to grow by 2 percent per year for the years 2011 through 2012, 3 percent per year for the years 2013 through 2015, and 4.52 percent per year for the years 2016 through 2020. 4. Personnel costs are expected to increase annually by 7.5 percent for the years 2011 through 2012, and by 10 percent for the years 2013 through 2020, based on historical trends and projected benefit cost increases. 5. Other annual maintenance and operations expenses are anticipated to increase 2.5 percent in 2011, 3 percent in 2012, 3.5 percent in 2013, and 4 percent for the years 2014 through 2020, based on historical trends and projected increases in the Seattle Consumer Price Index (CPI -U). 6. Capital Improvement construction costs are expected to increase annually by 3 percent to 4 percent over the 10 -year period. 7. Annual debt service expenses will equal scheduled payments for current outstanding revenue bond issues. 8. Water rate increases are projected for each year to cover the impact of cost of local program operations, to fund outside water purchases, and to contribute to construction projects in lieu of issuing new bonds. However, bonding is anticipated for the years 2016 through 2020 to support the construction of new reservoirs.

Transfers to the capital improvement fund included in Table 10-2 represent anticipated funding needs for projects in the current (2011-2016) CIP. These funds will be updated to reflect the recommendations cited in this plan for future budget and rate projections. Other potential sources of funding for these recommendations include re -allocating funds from other lower -priority projects identified in the CIP, obtaining low-interest P1NTF loans for projects meeting eligibility requirements, adopting additional water service rate increases, or using ending fund balances. 10.6 WATER RATES In 2008, the City implemented a three -tiered inverted block rate structure for single-family residences and duplexes which promotes water conservation. In 2012, City Council approved a 16 percent rate increase. The City periodically conducts cost of service analyses and rate studies. The current (2012) rate structure is summarized in Table 10.3.

SEATTLE is willing to provide water to RENTON at wholesale water rates under the terms set forth herein; 3. SEATTLE and RENTON have mutually agreed to a maximum daily rate of delivery and a maximum volume from SEATTLE on an annual basis; 4. SEATTLE and RENTON have mutually agreed, in a separate agreement, that SEATTLE will provide Fire Flows at certain Service Connections; 5. SEATTLE and RENTON have mutually agreed that SEATTLE will provide an emergency supply to RENTON; 6. SEATTLE and RENTON have mutually agreed, in a separate agreement, that RENTON will provide an emergency supply to SEATTLE; NOW, THEREFORE, in consideration of mutual covenants herein, it is agreed as follows: I. TERM OF CONTRACT AND GUARANTEES A. Agreement To Supply And Purchase Water I . SEATTLE agrees to supply water to RENTON subject to the conditions of this Contract. 2. RENTON agrees to purchase water from SEATTLE subject to the conditions of this Contract. B. Terni of Contract Subject to the other provisions contained herein, the original term of this Contract shall commence and this Contract shall become effective November 1, 1998. 2. For the routine (non emergency) supply of water by SEATTLE to RENTON (Refer to Section Il_), the agreement shall be in effect until. December 31, 2011; or until RENTON enters into membership in the Cascade Water Alliance (CWA), whichever comes first_ Routine supply of water, as provided for in this part of the agreement, shall not be extended beyond December 31, 2011, unless the CWA Is not formed, in which case SEATTLE and RENTON may elect to renegotiate the sale of routine water. 3. For the emergency supply of water, including fire flow protection, by SEATTLE to RENTON (Refer to Section lt.), the agreement shall be in effect until December 31, 2038, as long as Seattle and Renton have mutual emergency water supply arrangements in effect; or until Renton enters into membership in the Cascade Water Alliance (CWA), whichever comes first_ 4. For purposes of fire protection for the area described in the Boeing Renton customer transfer area, SEATTLE will provide fire flows to the transfer area by means of the existing 12 -inch water mains in Logan Avenue, at a maximum rate of flow governed by the physical capacity of the existing mains; and conditioned also on the continued operation of the three transmission pipelines (Cedar River Pipeline Nos. 1, 2 and 3) to which the Logan Avenue water mains are connected. The obligation by SEATTLE to provide fire protection to the Boeing facility from the three transmission pipelines shall survive the termination or expiration of this contract; provided that a written agreement to address this service shall be negotiated subsequent to the termination or expiration of this contract. I1. CONDITIONS OF SERVICE A. Routine Supply of Water by Seattle to Renton Under normal circumstances, RENTON will draw water from the SEATTLE transmission pipelines via the current or reconfigured Service Connections in the vicinity of Logan Avenue and the Cedar River; only for the purpose of supplying water to the facilities located in the Boeing Renton service transfer area_ On occasion, RENTON may use the other service connections as the need arises. The total volume taken by RENTON, from all service connections in any given month, shall not exceed the total monthly consumption figures shown in Exhibit A to this contract. No prior coordination with SEATTLE is required if volumes 2 of water remain within this cap. If RENTON's water use exceeds the cap, under other than emergency conditions, the water use that exceeds the cap shall be subject to a two hundred percent (240%) surcharge. If it becomes necessary, under emergency conditions, to use more SEATTLE water, the provisions of Section II. B, would apply. B. Emergency Supply of Water by Seattle to Renton An "emergency" shall be defined as a major water main break; fire demand; contamination of water production wells, mechanical and/or electrical equipment failure; or interruptions in power supply, within the RENTON system. 2. Any combination of service connections on the SEATTLE transmission pipelines may be used to meet RENTON's needs during the emergency, 3. If RENTON experiences an emergency that requires emergency supply from SEATTLE, RENTON shall curtail its customers' water use commensurate with the nature and duration of the emergency. Before drawing on the SEATTLE water supply for emergency purposes, RENTON shall have activated all of its own backup sources of supply to cope with the emergency. It is understood that emergency supply from SEATTLE is conditioned on SEATTLE's sole determination of availability and Section II. C. Continuity of Service. SEATTLE shall not unreasonably withhold determination of availability, and in the event SEATTLE determines there are limitations on availability, then continuity of service to RENTON shall be maintained by SEATTLE, to the extent feasible, in the same manner as service to SEATTLE's other purveyor customers_ 4. During such emergencies, SEATTLE shall make available an amount not to exceed ten million (10,004,040) gallons per day from service connections on SEATTLE's transmission pipelines, for a period not to exceed three (3) years. Coordination prior to and during emergency operations shall be as follows.- a) ollows: a) For operation of the service connections, liaison shall occur between representatives of the systems, who are: Water Utility Supervisor (RENTON) and Water Treatment and Supply Manager (SEATTLE) or their designated representatives. h) For the purposes of discussing and resolving engineering issues, liaison shall occur between representatives of the systems, who are: Water Utility Supervisor (RENTON) and Water Resource Manager (SEATTLE) or their designated representatives. 3 C) For purposes of administration, liaison shall occur between representatives of the systems, who are: Administrator for Plan/Building/Public Works Division (RENTON) and Water Resource Manager (SEATTLE) or their designated representatives. C. Continuity of Service Continuity of service to RENTON shall be maintained by SEATTLE, to the extent feasible, in the same manner as service to SEATTLE's other Purveyor customers. In the event of a general emergency or water shortage affecting the entire regional service area requiring restrictions on the delivery of water, general restrictions placed upon deliveries to RENTON shall be determined by a similar method to that used for restricting deliveries to SEATTLE's other Purveyor customers_ In the event of localized emergency problems, temporary service interruptions may result. Z. It is recognized by both parties that emergency conservation measures may have to be implemented by SEATTLE on a regional basis in order to meet an emergency condition. RENTON shall assist and support such emergency conservation measures. 3. SEATTLE shall provide oral notice to RENTON, and may temporarily interrupt or reduce deliveries of water to RENTON, if SEATTLE determines that such interruption or reduction is necessary or reasonable in case of system emergencies, or in order to install equipment, make repairs, replacements, investigations and inspections or perform other maintenance work on SEATTLE's water system or those parts of the system supplying RENTON. Except in cases of emergency, and in order that RENTON's operations will not be unreasonably interfered with, SEATTLE shall give RENTON reasonable written notice of any such interruption or reduction, the reason therefore, and the probable duration thereof. D. Minimum Hydraulic Gradient A minimum hydraulic gradient or head for each Service Connection shall be used as a criterion for SEATTLE's and RENTON's comprehensive water planning efforts. If SEATTLE finds that it would benefit the Regional Water Supply System and purveyors as a class, the minimum hydraulic gradient or head in Exhibit B may be modified by SEATTLE, at its sole discretion, only once during the life of this contract; provided that four (4) years' advance notice is given to RENTON. 2. SEATTLE will use its best efforts to supply water from its system to that of RENTON at the points of connection and at not less than the minimum hydraulic 4 gradient or head at the inlet side of the Service Connection meter, as shown on Exhibit B., except as noted in this Contract. It is understood that circumstances may prevent SEATTLE from providing, at all times, this minimum hydraulic gradient. Additional Service Connections between RENTON's and SEATTLE's water systems or adjusted minimum gradients may be established from time to time, by mutual agreement between SEATTLE and RENTON, in which instance Exhibit Il. A. shall be appropriately amended to reflect such additional points of connection or adjusted minimum gradients_ E. Water Quality The quality of water delivered under this Contract shall comply with all applicable provisions of the State and Federal law and rules and regulations of the appropriate State and Federal agencies governing water quality; and shall be subject also to applicable provisions of SEATTLE ordinances relating thereto and not inconsistent herewith. 2_ Both parties agree that this provision will not be binding on SEATTLE in instances in which an emergency exists and best efforts and reasonable prudence have been exercised_ 3. RENTON may obtain water from other State approved sources without the written consent of SEATTLE. 4. RENTON and SEATTLE are responsible for the quality of the water in their respective distribution systems. F. Resale to Other Parties RENTON may sell water supplied to it by SEATTLE to other parties outside its existing or future boundaries for resale to ultimate consumers only upon written consent of SEATTLE (or oral consent, in case of an emergency). 5 G. Flushing Allowance Credit for water used for flushing water mains will not be awarded under this agreement. H. Metering Equipment SEATTLE shall own and maintain appropriate metering devices to measure the water flowing from SEATTLE's water system to RENTON at each Service Connection_ 2. The entire cost of each additional Service Connection, including the cost of meters, shall be paid by RENTON. 3_ Rehabilitation and/or replacement of master meter installations resulting from routine operations or safety requirements shall be at SEATTLE's expense. If SEATTLE removes and replaces a RENTON meter because it is under or over capacity (based on AWWA standards or factory rating criteria), or where RENTON desires to change, interrupt or discontinue a service connection, then the net cost of these changes shall be paid to SEATTLE by RENTON_ 4. In regard to the Boeing Customer transfer area, RENTON shall, upon execution of this agreement, prepare two (2) master meter relocation designs within 6 months. It shall also complete the installation within two (2) years of design completion and approval by SEATTLE. RENTON shall be allowed to relocate the two (2) new meters recently installed by SEATTLE in these meter relocations as long as the accuracy meets SEATTLE's requirements. RENTON shall be responsible for all costs associated with developing the new metering arrangement, including but not limited to, design, infrastructure, site acquisition and easements, construction, and SEATTLE's in-house costs for coordination and inspection, excluding costs for relocated meters. III. COST OF WATER A. Rates to be Based on Purveyor Wholesale Rates Rates charged by SEATTLE to RENTON for water service shall be based on the wholesale rates charged to other purveyors and by the factors set forth in Section M.

Rate Components Rates charged to RENTON will include all components of the wholesale rate schedule with the following exceptions: Demand Charges will not be levied against RENTON and Growth Charges will not be levied,- Base Service Charges (monthly meter charges) shall apply to all meters, existing or future, except for account numbers 0I748610-005 (G -inch meter), 01748620-005 (3 -inch meter), and 01748670-005 (6 -inch meter). The Rate Adjustment Factor, as defined in item E. below, shall not be applied to the Base Service Charges, D. Old Water Allowance RENTON's old water allowance is defined in Exhibit A. For the purpose of this agreement, the old water allowance is used to establish a threshold between routine water usage and water that would be charged by a 200% surcharge (i.e, three times rate adjustment factor times commodity charge), as defined in Section II. Conditions of Service, E. Rate Multipliers_ E. Rate Multipliers The effective rate to RENTON is the Commodity Charge Rate for Wholesale Customers, in SEATTLE's rate ordinance, multiplied by a Rate Adjustment factor. The growth surcharge, as specified in the purveyor contracts (Section III. C. Purveyor Rate Structure), shall not be applicable to water purchased under the terms of this agreement. The following factors will be used: Time Period Rate Adjustment Factor 1998 through date of completion of Boeing Renton meter replacement 1.30 Boeing Renton meter replacement completion through 2011 1.05 If an emergency arises that meets the condition specified in Section 11, B. Emergency Supply of Water by SEATTLE to RENTON, the Rate Adjustment Factor shall be 1.0 7 for the duration of the emergency for that volume of water used for emergency purposes. F. Possible Phaseout of Wholesale Rate In the event that the number of Purveyor customers of SEATTLE declines to the point that SEATTLE no longer intends to offer a wholesale rate in its rate ordinance, SEATTLE will notify RENTON 180 days in advance of the ordinance change_ SEATTLE and RENTON agree to develop a replacement set of charges for service under this contract within that 180 day period. IV. PAYMENT A. Collection of Money Due RENTON shall be billed by SEATTLE on a monthly basis for the supply of water delivered by SEATTLE_ RENTON shall pay these water bills within sixty (60) days of the billing dates_ B. Penalties for Late Payment SEATTLE may assess a late charge on RENTON for failure to make full and timely payment as provided in Section IV. A. This late charge shall be established by SEATTLE as a percentage of the late portion of the water charges owed, provided that the percentage rate shall not exceed the maximum amount permissible by law. C_ Disputes RENTON may dispute the accuracy of any portion of the water charges by taking the following two actions within the sixty (60) day payment period established in Section IV. A: (1) notifying SEATTLE in writing of the specific nature of the dispute, and (2) paying the undisputed portion of the water charges_ SEATTLE shall consider and decide any billing dispute in a reasonable and timely manner.

WHEREAS, SEATTLE and RENTON have existing interties between their water systems; WHEREAS, SEATTLE sometimes experiences a Spring water supply shortage due to low snowpack, precipitation and inflows in the Cedar and Tolt River watersheds, or, a hot Summer with high water consumption coupled with a delay in usual Fall rains; WHEREAS, SEATTLE may also experience other types of emergency situations that call for an augmentation of its water supply, such as a transmission pipeline break or an episode of high turbidity in one of its reservoirs; WHEREAS, RENTON, in the spirit of intergovernmental cooperation during such water supply emergencies, is willing to sell an increment of water to SEATTLE when available during non -peak periods; WHEREAS, SEATTLE is willing to sell water to RENTON to allow RENTON's ground water aquifer to recharge, when water is available following a water shortage emergency; and, WHEREAS, the parties desire to enter into an AGREEMENT providing for the sale of water in an emergency from RENTON to SEATTLE, and for the subsequent sale of an equivalent amount of water from SEATTLE to RENTON, if necessary, to allow recharge of RENTON's Aquifer. NOW THEREFORE, IT IS AGREED AS FOLLOWS: 1) Term of AGREEMENT. The effective date of this AGREEMENT shall be 2002. The AGREEMENT shall be in effect until December 31, 2011, unless terminated by either party in accordance with Section 17 of this AGREEMENT. The rates and quantities of water sold are set forth in Sections (2), (8), and (11). 2) Sale Price of Renton Water. SEATTLE shall pay to RENTON for all water delivered $1.30 per 100 cubic feet, which is a special wholesale rate for 2002; and revised each year during the term of the agreement. The rates charged by RENTON are based on RENTON's analysis of cost of providing non -peaking service to Seattle under the conditions stated herein. This rate was calculated using the American Water Works Association (AWWA) "Base Extra Capacity" method of rate analysis. The rate charged to SEATTLE shall be adjusted each year using the AWWA "Base Extra Capacity" method and RENTON's retail water rate for each year.

A monthly meter charge shall be paid by SEATTLE in accordance with the meter charges as stated in RENTON's City Code at the time the meter is in service. 6) Priority and Continuity of Service. The determination of whether water is available for SEATTLE shall be at the sole discretion of RENTON. In the event of a condition requiring restrictions on the delivery of water, RENTON shall have the right to restrict or interrupt service to SEATTLE. RENTON may voluntarily interrupt or reduce deliveries of water to SEATTLE if RENTON determines that such interruption or reduction is necessary or reasonable. Except in cases of emergency and in order that SEATTLE's operations will not be unreasonably interfered with, RENTON shall give SEATTLE reasonable notice of any such interruption or reduction, the reason therefor, and the probable duration thereof. SEATTLE shall discontinue or reduce service from RENTON upon reasonable notice to RENTON. Service shall be reactivated or increased again subject to the aforementioned conditions. 7) Water Quality. The quality of water delivered under this AGREEMENT shall comply with all applicable provisions of State and Federal law and rules and regulations of the appropriate State agency governing water quality. In addition to the above requirements, RENTON agrees to deliver water which shall be of no less quality than is delivered to its customers throughout the RENTON service area. Prior to any delivery of water, information on current water quality will be provided to the receiving party so that blending, compatibility and other water quality issues can be evaluated and addressed. (8) Quantity of Water. Depending upon water availability in the RENTON system, RENTON shall make available for purchase by SEATTLE up to the approximate amount of two million (2,000,004) gallons per day from the existing emergency intertie located at the Tiffany Park Pump Station. The rate of delivery of water from Tiffany Park Pump Station system to SEATTLE's system shall vary between zero and approximately 1,400 gallons per minute. Also in the fall and winter RENTON may make available an additional amount up to approximately three and one-half million (3,500,000) gallons per day from the intertie at Union Avenue SE and SE 2nd Street. The rate of delivery of water from this intertie shall vary between zero and approximately 2,400 gallons per minute.

It is recognized that runoff into SEATTLE's surface water storage facilities generally exceeds the storage capacity during the winter and spring months. It may be necessary, due to RENTON supplying water to SEATTLE, to allow RENTON's aquifer to recharge during the winter and spring months. Following a water shortage emergency and recovery of SEATTLE's water system impoundments on the Cedar and Tolt Rivers, SEATTLE will sell water to Renton. The water sale will be based on availability at the intertie locations between SEATTLE and RENTON's systems and at such flow rate as is available from the intertie location during the following winter or spring. The quantity of SEATTLE's water, made available for allowing RENTON's Aquifer to recharge, shall not exceed the quantity of water that was supplied by RENTON to SEATTLE during the water shortage emergency. SEATTLE will sell the water to RENTON at $0.77 per 100 cubic -feet which is SEATTLE's non -peak, old water rate charged by SEATTLE to its purveyors in 2002. This rate shall be revised each year during the term of the agreement. This flow rate, quantity and price is an integral part of this AGREEMENT and should not be considered as a precedent in possible future water sales to RENTON or to other existing or future wholesale customers. The determination of whether water is available for RENTON, to allow RENTON's Aquifer to recharge, shall be at the sole discretion of SEATTLE. SEATTLE may voluntarily interrupt or reduce delivery of said water, providing that such interruption or reduction is necessary or reasonable. Except in cases of emergency, and in order that Renton's operations will not be unreasonably interfered with, SEATTLE shall give RENTON reasonable notice of such interruptions or reduction, the reason therefor, and the probable duration thereof. 12) Payment. The party supplying water shall read the meter once each month at approximately thirty (30) day intervals. Payment shall be made by the party receiving water as soon as possible after receipt of statement from the party supplying water, and in any event, not later than the tenth (10) of the second month following the presentation of the bill. In the event a meter shall fail to register or obviously register incorrectly, the amount of water considered delivered through said meter shall be the amount delivered the previous day or the last day that the meter was previously known to be properly functioning and the total amount registered shall be pro -rated based on the number of days multiplied times the reading used. 13) Penalties For Late Payment. The party supplying water may assess a late charge on the party receiving water for failure to comply with the provisions in Section (12). This charge shall be at the rate of twelve percent (12%) per year. In the event that the party receiving water should fail to make any payment for a period of sixty (60) days after the same becomes due, the party supplying water shall have the right to terminate further water service until such delinquency is cured. 14) Procedure for Amending the Contract. Either party can request the other to consider an amendment of the AGREEMENT. Any proposed amendments shall be made in writing. Amendments may be made if they are mutually acceptable to RENTON and SEATTLE and signed by both parties.

Service Area Boundaries. The undersigned utility acknowledges that the Skyway Overall Water Service Area Map, included as Attachment A to the agreement, identifies the utility's proposed new water service area. Existing service areas are identified in the CWSP. The undersigned also acknowledges that there are no water service area conflicts with adjacent water utilities, or, where such conflict exists, agrees that no new water service will be extended within the disputed area until such conflict shall be resolved. SECTION 2. Transfer Areas. It is understood that utilities may initially continue providing water service within existing service areas which are within the boundaries of adjacent water service areas, as defined in Section l hereof, and which shall be known'as transfer areas. Such transfer areas, if they exist for the undersigned utilities, are described in Attachment B to this agreement. The undersigned utility agrees that any retail water. service line extending outside of the proposed new service area boundary, as set forth in Section 1, shall be phased out and service transferred to the designated adjacent utility on an economic basis or by mutual agreement within the time frames indicated Attachment B. Economic basis considerations may include, but are not limited to: (a) A determination by the present owner of service lines that maintenance, repair and/or replacement costs exceed attributable income. (b) Planned or imminent major street improvements or major improvements to either or both water systems which include an opportunity to transfer service. SECTION 3. Service Within Transfer Areas. Provisions detailing responsibilities of each utility with regards to interim service, financial arrangements, facility extension, repair or replacement, and customer service issues within any transfer area, and the terms of the transfer of the service area, as specified in Section VII of the Skyway CWSP, shall be established in a separate agreement among adjacent utilities whose boundaries are affected. Financial responsibility for new facilities in transfer areas will be the responsibility of the benefitting property owners. t- ieA SECTION 4. Service Area Boundary Lines. Unless separate agreements exist with adjacent utilities, the undersigned agrees that the centerlines of public streets, roads or highways shall not he used to define any part of a service area boundary. Depth of service on boundary streets shall be limited to one platted lot or as otherwise agreed upon by the utilities. Existing services on boundary streets shall remain as connected unless transfer of service is agreed to by both parties, as per Section 2. Nothing in this agreement shall prohibit the placement of water mains in the same street by adjacent utilities where geographic or economic constraints require such placement for the hydraulic benefit of both utilities. SECTION 5. Boundary Adjustments. If, at some time in the future, it is in the best interest of the undersigned to make adjustments to the service areas agreed to herein, such modifications must be by written concurrence of all involved utilities and the proper legislative authorities.

Maintenance of Existing Facilities. THE DISTRICT and RENTON will each provide maintenance for its own facilities. If there are any serious problems due to a discharge which can be identified, and for which the source can be identified, the individual or company responsible will be held liable for damage. If a lack of maintenance, or if the type of maintenance by either RENTON or THE DISTRICT is identified as the source of said problem, then the party creating, or allowing, the situation shall be responsible and shall pay the costs of repair. In case of dispute over the source or responsibility of said problems, the Municipality of Metropolitan Seattle (Metro) shall serve as arbitrator in identifying and quantifying said problems provided that said arbitration and/or any reports generated by an investigation by Metro, shall be binding upon both parties in resolution of the dispute. Allowable Capacities in the Lines being Transferred and at Points Further Downstream. There are no restrictions on the capacity of the sewers from Ponderosa Estates as long as they are consistent with the current use of the properties. There are currently 35 single family residences, and the property is fully developed. If this condition ever changes, a further review of the capacity of the system shall be performed, and an additional agreement shall be developed between the parties. Capacity for the system in the Springbrook drainage basin shall be as follows: AT TIMES OF SIMULTANEOUS PEAK FLOW SOOS CITY OF RESERVED CREEK RENTON FOR CITY OF {gpm} (gpm) KENT (9pm) S. 192nd Street, at and below 1500 600 0 MH 34-3 aooaoag_oas Page 8 of 11 S. 1 92nd Street, at and below 1800 15070 0 MH 34 -OA S. 192nd Street, at and below 3900 1500 0 MH 80-14 West of MH 80-14 3900 1500 400 No connections, by either party, will be allowed between Manhole 34 -OA and Manhole 80-15 except by mutual agreement. Both parties agree that either may exceed this amount at the non -peak times, as long as there are no negative impacts, and the combined capacity of the system is not exceeded, and prior notification is given to the other party. It shall be the responsibility of each part to monitor its flow as and when necessary to determine what the flow rate characteristics of the system are. If the combined capacity of the system is exceeded, the party exceeding its allowable rate shall have the option of making revisions within its own system to bring its flows into compliance with this Section, or of paying for improve- ments to either system which will increase the available capacity of the systems. If both parties exceed their allowable rate, the cost of any new facilities will be divided based upon the ratio of the percentage by which each party is exceeding its allowable rate. If the allowable rate is exceeded at -only one location, the ratio at that location will be used. If the rate is exceeded at more than one location, the ratio will be based upon the furthest east point at which the allowable rates are being exceeded. If a regular surcharge condition exists that is not due to a blockage problem, a previously agreed upon temporary situation such as re-routing for construction, or by either party exceeding its capacity, the DISTRICT shall have the option of making revision within its own system to bring its flows into compliance with this section, or of paying for improvements to either system which will resolve the surcharge condition. Both parties acknowledge and agree that the City of Kent. is not a party to this agreement, and'the amount referenced for the City of Kent is for reference only and could be the basis for a separate agreement in the future involving THE DISTRICT and the City of Kent, and involving RENTON if their rate allowance is at all to be affected. 13. Connection of THE DISTRICT to RENTON Facilities, or RENTON_ to THE DISTRICT Facilities. Connection of facilities of either RENTON or THE DISTRICT to facilities of the ether, or to facilities tributary to facilities of the other, shall be coordinated by both parties to assure: a) Payment of appropriate charges, b) up-to-date accounting of connections, C) potential sources of -debris, or construction damage, are identified, and 4-7:0400400g.oai Page 9 of 11 d) inspection of connection construction can be scheduled.

Future Annexations to RENTON. The service areas listed in sections 1-7 of this AGREEMENT are the only areas of cross -service agreed to at this time. RENTON shall serve all other areas within RENTON without challenge by THE DISTRICT, based upon the City limits at the date of the agreement. THE DISTRICT shall serve all areas within THE DISTRICT's limits at the time of this agreement, except as previously detailed. Future annexation to RENTON shall not limit THE DISTRICT providing water or sewer service to those areas within THE DISTRICT limits to the standards of THE DISTRICT, even if there is conflict with RENTON standards, unless this is altered by future agreements.

Flushing allowances will be provided by Seattle only when the Operating Board determines that flushing is required to maintain or improve regional water quality. 9. New Water Sources. Prior to the introduction of any new water supply source, including any direct or indirect potable reuse water, by Water Utility which mixes with water in the Seattle Regional Water Supply System, the proposed source must be evaluated using customary and reasonable water quality criteria developed in consultation with the Operating Board to ensure compatibility with Seattle water and approved in writing by Seattle. The proposed Water Utility source must also meet all federal, state and Seattle water quality and treatment standards. Upon Seattle's request, Water Utility shall also provide Seattle with satisfactory results from a blending study to determine the compatibility of the source with existing sources already in the Seattle Regional Water Supply System, the appropriate method and level of treatment and the probable distribution of the new supply within the Seattle Regional Water Supply System. Water Utility shall also complete a flavor rating analysis of no more than 3.0 as tested by Seattle's flavor profile panel according to the methodology described by the American Water Works Association, or its successor. Water Utility shall obtain all necessary and appropriate regulatory permits, reviews, and approvals for rights to and operational use of such water supply source. PARTULL REQUMMENTS CONTRACT CITY OF PENTON Page 13 The Operating Board may form a technical subcommittee to develop water duality standards and review and advise on the water quality evaluation criteria for proposed new sources. Such criteria for new sources shall be the same for surface water and ground water. 10. Transfers Outside the Seattle Regional Water Supply System. If, with the written consent of Seattle, water from the Seattle Regional Water Supply'System is transferred between Water Utility and another water utility in a manner that does not use the Seattle Regional Water Supply System, Water Utility, the other water utility, or both, shall be fully responsible for meeting all applicable water quality standards related to the transfer of such water between their respective systems. Seattle will not be responsible for water quality outside of the Seattle Regional Water- Supply System or Seattle Retail Distribution System except as may be agreed to under Section II.D.S. 1I.E. Conservation The parties acknowledge that conservation prolongs the time before new supply resources are needed and thus constitutes an important ongoing tool in managing the water resources of the region. Accordingly, Water Utility hereby adopts and agrees to be bound by the Regional Water Conservation Program, as it may be amended from time to time during the term of this contract. In accordance with Part 1, Section B. L5 of the Settlement Agreement between the Muckleshoot Indian Tribe and the National Marine Fisheries Services and the City of Seattle (Civ. No. 03- 3775JLR), Water Utility will implement, through its participation in the Regional Water Conservation Program, conservation measures that are substantially similar to those implemented by Seattle within the Seattle Retail Distribution System. PARTIAL, REQUIREMENTS CONTRACT CITY OFRENTON Page 14 1. Performance Measurements. For the purposes of determining water conservation performance, Water Utility's water use shall be measured in conjunction with the use of all other participants in the Regional Water Conservation Program. The Operating Board may develop reasonable criteria to measure the participants' water conservation performance in accordance with such program. 2. Conservation Above the Regional Water Conservation Pro am. Water Utility acknowledges that water conservation beyond -the Regional Water Conservation Program may be required as a condition of State or federal regulations, court orders, settlements or agreements made to avoid litigation, fines or penalties, or as otherwise determined to be reasonably necessary by the Operating Board. The Operating Board may adopt reasonable additional conservation measures and targets for such purposes. Such conservation measures and targets shall apply in the same manner to all holders of Full and Partial Requirements Contracts and the Seattle Retail Distribution System. Except as provided in the next subsection, Water Utility shall implement such additional water conservation measures and meet the additional adopted targets. 3. Water Utili 's Option to be Conservation Service Provider. Water Utility may elect to provide its own water conservation program, beyond its commitment to the Regional Water Conservation Program to meet conservation targets adopted by the Operating Board, or more stringent targets. Water Utility shall bear the additional costs thereof and shall be solely responsible for its implementation. Under this option, Water Utility shall be evaluated for meeting the additional water conservation targets solely by its own performance. PARTIAL REQUIREMENTS CONTRACT CITY OF RBNTON Page 15 4. Incentives and Penalties. The Operating Board may adopt penalties for shortfalls in water conservation and rewards for meeting or exceeding adopted targets. In the event Water Utility or Seattle fails to meet the adopted targets set by the Operating Board, the Operating Board may assess a penalty. Penalties may not exceed the cost of Seattle undertaking those conservation measures reasonably needed to achieve the adopted target. 5. Postponing the Need for New Water Supply Facilities. In order to avoid the necessity of developing new physical water supply facilities for as long as reasonably practicable, any water saved through conservation in either Seattle's or Water Utility's retail service areas shall be dedicated first to the municipal and industrial water supply requirements of the Seattle Regional Water Supply System before any other use of such water may be undertaken. SECTION III. CONDITIONS OF SERVICE III.A. Minimum Hydraulic Gradient 1. Initial Minimum. Seattle shall maintain a minimum hydraulic gradient or head at a maximum flow rate in amounts and at locations described in Exhibit II attached hereto for each Service Connection from the Seattle Regional Water Supply System to Water Utility's distribution system. Such gradients and locations shall be contained in Seattle's and Dilater Utility's future water system plans. Seattle shall operate and maintain the Seattle Transmission Facilities necessary to carry out such obligation. If Seattle and the Operating Board find that a project resulting in the modification of such minimum gradient or head would benefit the Seattle Regional Water Supply System as a whole, the minimum hydraulic gradient or head described in Exhibit II may be modified by Seattle if PARTIAL RLQi MAffiNTS CONTRACT CITY OFRENTON Page 16 such modification is feasible from an economic, land use and engineering perspective taking into account the facilities required to carry out and for Water Utility to adapt to such modification. Seattle may make these modifications only once during any fifteen (I5) year period provided that four (4) years advance written notice is given to Water Utility, unless a shorter notice is approved by the Operating Board. 2. Emerizencies. If Seattle is prevented by emergency circumstances from providing such minimum hydraulic gradient, Seattle shall supply not less than the volume of water equivalent to the maximum 24-hour average flow rate required by Water Utility as shown on Exhibit II for each 24 hour period that the minimum hydraulic gradient is interrupted. 3. AdditionaI Service Connections, Additional Service Connections between Water Utility's and Seattle Regional Water Supply System's water systems or adjusted minimum gradients may be established from time to time by mutual agreement between Seattle and Water Utility subject to approval by the Operating Board. Exhibit 11 shall be appropriately revised to reflect such additions or adjustments. HLB. Resale to Other Parties Water Utility may sell water supplied by Seattle to other water utilities located outside of Water Utility's existing or future service area only upon the prior written consent of Seattle (or oral, in case of emergency): Agreements for resale of water by Water Utility listed in Exhibit I are hereby approved by Seattle subject to whatever written terms, conditions and limitations that Seattle has imposed on such resale. PARTIAL REQUMEMENTS CONTRACT CITY OF RENTON Page 17 IH.C. Interconnection With Other Systems 1. Prohibition on Interconnection. Water Utility shall not interconnect any part of its system supplied with water from Seattle with other water systems without the prior written approval of the Operating Board, or, in case of emergency, upon oral approval by Seattle, which shall not be unreasonably withheld. Any such interconnection shall be subject to the approval of the Washington State Department. of Health and the installation of a meter. Such other systems must be in compliance with all applicable local, State and federal laws and regulations including the requirement that they have a valid operating permit issued by the Washington State Department of Health. 2. Requests by Seattle to Interconnect. Seattle may request that Water Utility interconnect its water system to the water system of an adjacent Wholesale Customer. Water Utility shall comply with that request subject to the terms and conditions set forth below. a. Requirement for- Interconnection. If Water Utility does not consent to Seattle's request for interconnection, Seattle may propose the interconnection of Water Utility's water system to the adjacent Wholesale Customer to the Operating Board. Water Utility may present facts and arguments to the Operating Board in opposition to the interconnection and document its costs in making the interconnection and conveying water to the adjacent Wholesale Customer. The Operating Board shall hear and consider the matter. Upon (a) a written finding by the Operating Board that the proposed interconnection with an adjacent Wholesale Customer is feasible taking into account Water Utility's capabilities, limitations, and obligations, (b) a written finding by the Operating Board that such interconnection benefits the Seattle Regional Water Supply System and (c) a PARTIAL REQUIREMENTS CONTRACT CITY OF RENTON Page 18 written demand of the Operating Board that Water Utility carry out the interconnection, Water Utility shall be required to interconnect its facilities to the adjacent Wholesale Customer for the purpose of supplying water to that Wholesale Customer through the distribution system of Water Utility, provided that the adjacent Wholesale Customer agrees to perform the interconnection in a location and according to a schedule which does not unduly disrupt Water Utility's operations, and to be responsible for the payment and indemnity obligations in Section III.C.2.b below. b. Payment and Indemnity. Water Utility shall be paid its actual costs of providing such interconnection and water transmission service by the adjacent Wholesale Customer receiving the water, plus a reasonable amount for overhead, administration and rate of return (equal to Rate of Return on Investment) on such costs, and Water Utility shall be indemnified from any liability that may result from providing such interconnection by the adjacent Wholesale Customer, The Operating Board shall adopt a standard methodology for calculating costs that ensures that Water Utility is fairly compensated for such service. III.D. Development of Regional Supply and Transmission Infrastructure Final decisions and authority to approve construction of capital infrastructure related to the Seattle Regional Water Supply System shall rest with the Seattle City Council. Capital construction activities include, but are not limited to installations, renewals, replacements, upgrades, expansions, and any other costs included in Seattle's comprehensive capital facilities plan. PARTIAL REQUIREMENTS CONTRACT CITY OF RENTON Page 19 III.E. Metering Equipment Seattle shall own and perform testing, cleaning and recalibration on appropriate metering devices and associated appurtenances to measure the amount of water delivered to Water Utility at the Service Connection pursuant to this contract. Seattle shall perform all other work at Water Utility's expense regardless of the cause provided that the cause is consistent with AWWA and safety standards and practices. Water Utility shall operate and maintain its water system in a manner that the water flowing through the Service Connection meter operates within the normal operating range for the meter as specified by the manufacturer. Until such time as Seattle determines it to be .economical to install metering devices to measure the amount of water delivered from the Seattle Regional Water Supply System to the Seattle Retail Distribution System, the amount of water delivered to the Seattle Retail Distribution System shall be measured indirectly by subtracting the metered water delivered to all of Seattle's wholesale customers from 98% of the total amount of water exiting Seattle's sources of supply as measured by the supply meters. SECTION IV. COST OF WATER SUPPLY & TRANSNUSSION Cost -based rates are a water industry accepted practice and the historical practice of Seattle and the Wholesale Customers. The rate -making principles, policies and methodologies set forth in this Section IV are intended to meet the objective of equitable and cost -based rates. N.A. Rate -making and Cost -allocation Principles The parties will apply the following general principles and policies to the establishment of all rates, charges, and cost allocations for water supply, transmission, and related services under this contract. PARTLAL REQUIREMENTS CONTRACT CrrY OF RENTON Page 20 I. No expenses attributable to electric power development may be allocated to the cost pools identified herein unless the pools are allocated a commensurate share of revenue derived from such development. 2. Seattle shall utilize generally accepted accounting principles, as may be amended from time to time, consistently applied as a basis for developing the financial information upon which rates and charges are based. 3. Abrupt changes in financial policies should be avoided. 4. The rate structure should encourage the efficient use of water, conservation and the timely development of new environmentally responsible water sources and should incorporate seasonal rates and other pricing approaches to encourage efficient use. 5. The rate structure should be innovative, flexible and adaptive whenever it is cost effective and beneficial in furthering the rate -making policies. 6. The rate structure should be simple to administer and easily understandable. 7. The rate structure should be fair and equitable while balancing the needs of all parties. 8. Capital costs which benefit only a new Wholesale Customer shall be allocated to that customer and not to any cost pool described in this contract. 9. Capital costs associated with improvements or facilities which benefit or serve individual Wholesale Customers or the Seattle Retail Distribution System may be allocated to a sub - regional or regional cost pool to the extent necessary to alleviate a disproportionate adverse impact to that Wholesale Customer or the Seattle Retail Distribution System from a regional or sub -regional capital improvement and where (i) such impact could have been reasonably avoided through a different project design, or (ii) the other PARTIAL REQUIRE14IENTs CONTRACT CITY OF RENTON Page 21 Wholesale Customers, including the Seattle Retail Distribution System, receive tangible benefits, directly or indirectly, from the adopted capital facilities plan. 10. The Seattle Retail Distribution System shall be treated as the equivalent of a Wholesale Customer of the Seattle Regional Water Supply System for the purpose of charging Seattle the same wholesale rates and charges as Water Utility for water supply and transmission. Costs calculated under the costs pools described below shall apply to all Wholesale Customers and to the Seattle Retail Distribution System, except as otherwise stated in a particular wholesale water supply contract. 11. The allocation of costs associated with capital construction activities within the Seattle Regional Water Supply System shall be the responsibility of the Operating Board. The Operating Board shall use its best efforts to determine and approve a cost allocation method for infrastructure projects prior to the capital project obtaining construction approval from the Seattle City Council. Failure of the Operating Board to determine and approve a cost allocation method shall not hinder the Seattle City Council from approving capital infiastructure projects in order to assure Seattle's ability to fulfill the requirements of this contract. 12. All parties will use best efforts in establishing rates and cost allocations that reflect the rate -making and cost allocation principles set forth in this Section IV.A. IV.B. Ratemaking Framework Subject to the foregoing principles, wholesale rates and charges for the services described in this contract shall be developed by Seattle based on the following framework: 1. Water Soply and Transmission Service. The costs of water supply and transmission of water shall be accounted for separately in the water supply and transmission cost pools PARTIAL REQUMEWNIS CONTRACT CITY OF RENTON page 22 described below. The price for each service shall be recovered through separate rates for each service. All direct costs incurred in providing water supply and transmission services shall be allocated to the appropriate cost pool and recovered through the rates for each service. In addition, certain indirect costs consisting of a reasonable overhead and administration cost shall be allocated to the appropriate cost pool and recovered through rates for each service. 2. Water Supply - Basic and Elective_ Services. The costs of supplying water falls into two categories — basic and elective services. Basic service costs include direct and indirect costs attributable to the delivery of water to the Wholesale Customers and to Seattle's Retail Distribution System pursuant to the foregoing principles. Elective services are optional services, such as water quality laboratory services and specific engineering support that Seattle makes available. 3. Conservation. Costs incurred by Seattle for the Regional Water Conservation Program shall be allocated to both the New Supply Cost Pool and Renton New Supply Cost Pool, which is defined in Section N.C.l.c. Only the Renton New Supply Cost Pool will be allocated to Water Utility in accordance with Section 1V.E.7 and the costs shall be recovered through a block payment in accordance with Section VII.A. 4. Block Payments In Lieu of New Sup& Rates or Facilities Char es. Water Utility's payment of the annual costs allocated to it through the Renton New Supply Cost Pool will be in lieu of paying new supply rates or facilities charges under this contract. Accordingly, Seattle will set a rate for Water Utility consisting of the existing supply rate, existing transmission rate and new transmission rate only. PARTIAL REQUMENIENTS CONTRACT Crrx of RENTON Page 23 IV. C. - Water Supply Pricing — Basic Services 1. Three Water Supply Cost Pools. For the purposes of determining costs of water supply, there shall be three cost pools: An existing supply cost pool ("Existing Supply Cost Pool'), a new supply cost pool (" New Supply Cost Pool") and a new supply cost pool for Renton {"Renton New Supply Cost Pool") authorized under Section 1V.E.5.a and defined in Section N.C.l.c below. a. Existing Supply Cost Pool. The Existing Supply Cost Pool shall be accounted for as follows: i. A basic services rate for water supply shall be charged to recover the full costs of operating, maintaining, repairing, renewing and replacing the Existing Supply Resources incurred by Seattle. ii. All regional conservation programs undertaken by Seattle prior to January 1, 2002, shall be considered an Existing Supply Resource cost. iii. Renewal and replacement of Existing Supply Resources will be an Existing Supply Resource cost. b. New Supply Cost Pool. The New Supply Cost Pool shall be accounted for as follows: L Water supply resources developed after January 1, 2002 that expand the capacity of the Seattle Regional Water Supply System ("New Supply Resources"), including the costs of the Regional Water Conservation Programa from January 1, 2002, shall be included in the New Supply Cost Pool. if any portion of a New Supply Resource project enhances reliability of Existing Supply Resources, the costs thereof may be PARTIAL REQUIREMENTS CONTRACT CITY OF RENTON Page 24 allocated to the Existing Supply Cost Pool if the Operating Board and Seattle both agree, ii. The cost of New Supply Resources plus Rate of Return on Investment may be recovered either through FCs or new supply rates charged to the holders of Full and Partial Requirements Contracts, except for Renton, and the Seattle Retail Distribution System. The new supply rate shall be applied to all holders of Full and Partial Requirements Contracts, except for Renton, and the Seattle Retail Distribution System, iii. The Operating Board shall determine the portion of the New Supply Resource costs that shall be recovered through FCs or through new supply rates. The FCs and new supply rates may be scalable to create an incentive for developers to build housing or commercial units with efficient water usage levels. Wholesale Customers and Seattle in setting rates for retail customers shall be free to choose the method of incorporating FCs or new supply rates into their own retail rates and charges. iv. Holders of Full and Partial Requirements Contracts who have not purchased water from Seattle under the 1982 Water Purveyor Contract shall be assessed the full marginal costs of the operation, including Rate of Return -on Investment, of the New Supply Resources. This assessment may be satisfied by either paying FCs and new supply rates or arranging a special water supply rate in lieu of paying FCs. PARTIAL REQUIREMENTS CONTRACT CITY OF RENTON Page 25 C. Renton New Supply Cost Pool. The Renton New Supply Cost Pool shall be accounted for as follows: i. New Supply Resources developed after January 1, 2012, including the costs of the Regional Water Conservation Program from January 1, 2012, shall be included in the Renton New Supply Cost Pool. ii. The cost of the New Supply Resources plus Rate of Return on Investment will be recovered through a block payment in accordance with Section VII.A. d. Emergency Surcharge. In the event of a drought, catastrophe, or other extraordinary condition that requires emergency expenditures to maintain a sufficient water supply, Seattle may impose an emergency surcharge on all holders of Full and Partial Requirements Contracts in order to pay for such expenditures or maintain financial stability of the Seattle Regional Water Supply System, or both. Any such emergency surcharge shall be presented to the Operating Board prior to adoption by the Seattle City Council. Seattle shall consider the comments of the Operating Board but shall nevertheless have the full authority to adopt the emergency surcharge. IV.D. Transmission Pricing - Basic Services 1. Transmission Costs Pools. For purposes of determining the cost of the transmission of water to the Wholesale Customers there shall be three transmission cost pools consisting of an existing transmission cost pool ("Existing Transmission Cost Pool"), a new transmission cost pool ("New Transmission Cost Pool'), and a Renton Sub -regional Cost Pool ("Renton Sub -regional Cost Pool'). PARTIAL REOUIREMENTs CONTRACT CITY OF RENTON Page 26 a. Existing Transmission Cost Pool. Costs to be allocated to the Existing Transmission Cost Pool shall consist of the following: operation, maintenance, repairs, renewals, and replacements to the Seattle Transmission Facilities. i. The Seattle Transmission Facilities are owned and operated as a regional network by Seattle to convey water to wholesale customers and to the Seattle Retail Distribution System. Therefore, the price of transmission for water transmitted within the Seattle Transmission Facilities shall be calculated on the same basis to holders of Full and Partial Requirements Contracts and the Seattle Retail Distribution System. ii. Costs incurred for purposes of transmission reliability may be included in the Existing Transmission Cost Pool subject to the approval of the Operating Board and Seattle. b. New Transmission Cost Pool. The cost of new transmission facilities shall be included in the New Transmission Cost Pool. The renewal, replacement, upgrade, expansion, or modification of existing Seattle Transmission Facilities which create an expansion of transmission capacity may be allocated to the New Transmission Cost Pool. The Operating Board shall decide what portion of costs of renewal, replacement, upgrade, expansion or modification of existing Seattle Transmission Facilities may be allocated to the New Transmission Cost Pool and what portion of costs of a transmission project that extends the geographic extent of the transmission system that shall be allocated to the New Transmission Cost Pool or recovered from a new Wholesale Customer if the project benefits only that new Wholesale Customer. Except for costs allocated to a specific Wholesale PARTIAL REQUIREMENTS CONTRACT CrFY OF RENTox Page 27 Customer, New Transmission Cost Pool costs shall be recovered through new transmission rates or FCs as determined by the Operating Board. The new transmission rate shall be applied in a uniform manner to all holders of Full and Partial Requirements Contracts and the Seattle Retail Distribution System. C. Renton Sub -regional Cost Pool. Water Utility is served, in part, by the sub - regional water transmission facilities listed in Exhibit XI. The costs of operating, maintaining, repairing and replacing these facilities shall be included in the Renton Sub -regional Cost Pool, together with any other costs Water Utility and Seattle agree to include. 2. Demand Charge. a. Seattle may adopt a demand charge in accordance with the methodology described in Exhibit Hl. The demand charge rate (i.e., dollars per 1000 gallons of deficient storage) shall be based on the equivalent cost of providing the deficient storage. b. The proceeds of the demand charge will be treated in rate setting as a credit to the New Transmission Cost Pool. c. Seattle shall suspend the demand charge rate in the event of emergencies and unforeseen conditions. 3. Cost of New or Chan gd Service Connection. If Seattle requests a change in the location of the Service Connection to Water Utility for the benefit of the Seattle Regional Water Supply System, then the costs, including any retirement costs of the old Service Connection, shall be included in the appropriate transmission cost pool. If Water Utility requests a new Service Connection or a change in location of an existing Service PARTIAL REQUIREMENTS CONTRACT CITY OF RENTON Page 28 Connection, then Water Utility shall pay the costs of the new or changed Service Connection, including any retirement costs of the old Service Connection regardless of the cause provided that the cause is consistent with AWWA and safety standards and practices. W.E. Allocation of Costs and Revenues into Cost Pools 1. Accounting. Seattle shall maintain a cost accounting system consistent with the provisions of this contract and generally accepted accounting principles, as amended from time to time, consistently applied in developing the financial information for determining the costs of acquisition, construction, repair, renewal, replacement, upgrade, expansion, maintenance, and operation of the facilities in each cost pool. a. Asset Accounts. An asset account shall be maintained for each facility and within that account Seattle shall record the original cost of that facility plus betterments and less retirements. b. Depreciation. Facilities shall be depreciated according to industry -standard water system asset lives and a record of life -to -date depreciation shall be maintained for each facility. No depreciation shall be recorded in the first calendar year of operation of a facility. A full year's depreciation shall be recorded in every subsequent year. C. Net Book Value. The net book value of any facility shall be its original cost plus betterments and less retirements as recorded in its facility asset account, less life - to -date depreciation. PARTIAL REQUIREMENTS CONTRACT MY OF RENTON Page 29 2. Infrastructure Costs. Each cost pool shall include the infrastructure costs for its respective facilities, calculated on a utility, cash or other basis depending upon the facility and the cost pool as set forth below. a. Utility. The utility basis shall be used to calculate the infrastructure costs for all Existing Supply Resources and Seattle Transmission Facilities, as well as their replacements and betterments. The utility basis may also be used for New Supply Resources and new transmission facilities in Seattle's discretion. Under the utility basis, the infrastructure cost for a facility in any year shall be the sum of (i) the annual depreciation expense recorded for that facility and (ii) the product of the net book value of that facility and the Rate of Return on Investment. At Seattle's discretion, interest costs may be considered current infrastructure costs during the construction of a facility. However, any such interest costs must be considered contributions in aid of construction, and not included in the Net Book Value of the facility for purposes of calculating Utility Basis costs in future years. b. Cash Basis. The cash basis may be used in Seattle's discretion for New Supply Resources and transmission facilities or a portion thereof. Under the cash basis, the infrastructure cost for a facility in any year shall be the actual cash expenditure made by Seattle in that year for either the payment of construction costs or actual principal and interest costs on debt issued to finance its construction. In the event that the depreciation lifetime of the facility is less than the term of the debt issued to finance all or a portion of the facility, debt PARTIAL REQUIREMENTS CONTRACT CITY OF RENTON Page 30 maturities will be selected such that the construction cost of the facility will be fully amortized at the end of its depreciation lifetime. C. Other Basis. Seattle, with the approval of the Operating Board, may determine one or more other bases on which to calculate infrastructure costs and may apply these bases to facilities in the New Supply, Renton New Supply, and New Transmission Cost Pools. Disposition of any facilities under another basis will be determined at the same time in accordance with Section IVIA 3. Operations Costs. The costs of operating the assets assigned to a cost pool shall be included in the cost pool. The annual operations costs of a cost pool shall be the labor, materials, equipment and other direct costs required for the operation, maintenance, and repair of the facilities in that cost pool, together with any net profit or expense from the disposition of facilities in that pool. Operations costs shall include the cost of general and administrative overhead applied in a manner consistent with its application to capital construction projects. a. Existing Supply Operations Costs.. The parties agree that an efficient way of handling operations costs for the Existing Supply Cost Pool shall be as follows: The operations cost base in the Existing Supply Cost Pool for the year 2010 shall be determined in accordance with the line item labeled "2010 Costs in identified activities" under Existing Supply in Note 2 — Operations Costs, Notes to the Wholesale Statements for the City of Seattle, Seattle Public Utilities, Water Fund, during the annual cost -audit process for 2010 in accordance with Section 1V.E.10, which occurs by the end of 2011 and applies to all Wholesale Customers and Seattle. Seattle will notify Water Utility of the actual 2010 operations cost base in PARTIAL REQUIREMENTS CONTRACT CCTY OF RENTON Page 31 the Existing Supply Cost Pool in writing, which shall become incorporated as part of this contract at that time. to each succeeding year, the amount of the operations cost base from the previous year shall be adjusted by the percentage increase in the operations cost in the Existing Supply cost centers identified in Exhibit IX, as amended from time to time. b. Existing Transmission Operations Costs. The parties agree that an efficient way of handling operations costs for the Existing Transmission Cost Pool shall be as follows: the operations costs base in the Existing Transmission Cost Pool for the year 2010 shall be determined in accordance with the .line item labeled "2010 Costs in identified activities" under Existing Transmission in Note 2 — Operations Costs, Notes to the Wholesale Statements for the City of Seattle, Seattle Public Utilities, Water Fund, during the annual cost -audit process for 2010 in accordance .with Section IV.E.10, which occurs by the end of 2011 and applies to all Wholesale Customers and Seattle. Seattle will notify Water Utility of the actual 2010 operations cost base in the Existing Transmission Cost Pool in writing, which shall become incorporated as part of this contract at that time. In each succeeding year, the amount of the operations cost base from the previous year shall be adjusted by the percentage increase in the operations cost in the Existing Transmission cost centers identified in Exhibit IX, as amended from time to time. C. New Supply _Operations Costs. The operation costs of the Regional Water Conservation Program after January 1, 2002, together with the costs of operating facilities assigned to the New Supply Cost Pool and any other costs allocated by the Operating Board, shall be assigned to the New Supply Cost Pool. The PARTUL REQUIREMENTS CONTRACT CITY OFRENTON Page 32 operations cost base in the New Supply Cost Pool for 2010 shall be determined in accordance with the line item labeled "20I0 Costs in identified activities" under New Supply in Note 2 — Operations Costs, Notes to the Wholesale Statements for the City of Seattle, Seattle Public Utilities, Water Fund, during the annual cost - audit process for 2010 in accordance with Section ME.10, which occurs by the end of 2011 and applies to all Wholesale Customers and Seattle. Seattle will notify Water Utility of the actual 2010 operations cost base in the New Supply Cost Pool in writing, which shall become incorporated as part of this contract at that time. In each succeeding year, the amount of the operations cost base shall be adjusted by the percentage increase in the operations costs in the New Supply cost centers as identified in Exhibit IX, as amended from time to time. d. Renton New Supply Operations Costs. The operation costs of the Regional Water Conservation Program after January 1, 2012, together with the costs of operating facilities assigned to the Renton New Supply Cost Pool and any other costs allocated by the Operating Board, shall be assigned to the Renton New Supply Cost Pool. The operations cost base in the Renton New Supply Cost Pool for 2012 shall be determined in accordance with the line item labeled "2012 Costs in identified activities" under New Supply in Note 2 — Operations Costs, Notes to the Wholesale Statements for the City of Seattle, Seattle Public Utilities, Water Fund, during the annual cost -audit process for 2012 in accordance with Section IV.E.10, which occurs by the end of 2013 and applies to all Wholesale Customers and Seattle. Seattle will notify Water Utility of the actual 2012 operations cost base in the Renton New Supply Cost Pool in writing, which shall become PARTIAL REQUIREMENTS coNTRAc r CITY OF RENTON Page 33 incorporated as part of this contract at that time. In each succeeding year, the amount of the operations cost base shall be adjusted by the percentage increase in the operations costs in the New Supply cost centers as identified in Exhibit IX, as amended from time to time. e. New Transmission Operations Costs. The actual costs of operating facilities assigned to the New Transmission Cost Pool and any other costs allocated by the Operating Board, shall be assigned to the New Transmission Cost Pool. f. Renton Sub -regional, Operations Costs. The actual costs of operating facilities assigned to the Renton Sub -regional Cost Pool, together with any additional operations costs approved by Water Utility and Seattle. 4. Disposition Costs. The costs of disposing of assets within a cost pool shall be included in the cost pool. Net disposition costs shall be calculated as follows: a. Disposition Under the Utility Basis. The net book value of the facility, less any sales, salvage, or other revenues derived from the disposition of that facility. b. Disposition Under the Cash Basis. The value of principal of unpaid maturities of debt used to finance the construction cost of the facility, less any sales, salvage or other revenues derived from the disposition of that facility. C. Disposition Under Other Basis. Disposition of any facilities whose infrastructure costs are calculated on another basis under section IV.E.2.c. above shall be determined by the parties as part of the definition of such other basis. 5. Creation of Additional Cost Pools. Seattle, in its discretion, may create additional cost pools to provide equity and flexibility in payment arrangements and the allocation of costs as the Seattle Regional Water Supply System expands to include new infrastructure, PARTIAL REQUIREMENTS CONTRACT CITY OF RENTON Page 34 operations, and customers. The costs in an additional cost pool, or a portion thereof, may be added to an existing cost pool subject to the consent of the Operating Board if the costs to be allocated satisfy the criteria for allocation to the existing cost pool. a. Creation of Renton New Supply Cost _Pool. The parties agree that, due to the unique circumstances that Seattle will provide Regional Conservation Program services throughout Water Utility's entire retail service area, but that Water Utility's purchases of water from the Seattle Regional Water Supply System are expected to be a minor portion of overall demand for Water Utility, the parties agree to an alternative cost recovery mechanism for the term of the contract in lieu of the new supply rates or FC's applicable to other Wholesale Customers. Accordingly, pursuant to this Section ME.5, Seattle is creating the Renton New Supply Cost Pool. 6. Facilities Charge Revenues. Supply FC revenues, which consist of those revenues from FCs the Operating Board has determined are to recover a certain portion of New Supply Resources costs, shall offset infrastructure costs in the New Supply Cost Pool. Surpluses and deficits in actual Supply FC revenues over costs to be recovered through the Supply FC shall be carried forward and earn simple interest at Seattle's Average Cost of Debt. Any current -year deficit (including any surplus balance available from previous years) shall be paid by gates for the New Supply Cost Pool. New Supply Cost Pool rates shall be discounted by surplus Supply FC revenues until any deficit Supply FC balance is repaid, except the amount of this discount shall not exceed, without the agreement of the Operating Board, twice the maximum annual deficit paid by the rate for the New Supply Cost Pool in any one year. PARTIAL RF,QUIREMENTS CONTRACT CITY OF RENTON Page 35 In the event that Supply FC surplus balances exceed the Net Book Value of assets whose costs are allocated to the Supply FC, the difference between the Supply FC balance and the Net Book Value of these assets shall be used to discount the rate for the New Supply Cost Pool (and the Supply FC surplus balance shall be reduced by the amount of this discount). The use and accounting for transmission FCs shall be done in,a like manner to supply FCs. Seattle and Water Utility agree that FC revenues are the sole property of Seattle. 7. Allocation of Cost Pools by Customer Class. The costs in cost pools shall be allocated within the pools as follows: a. Allocation of Existing Supply Cost Pool. The total cost of the Existing Supply Cost Pool shall be allocated to two customer classes as follows: L Block Purchase Customer Class. The portion of costs in the Existing Supply Cost Pool allocated to holders of BIock Purchase Contracts shall be determined pursuant to those contracts. ii. Full and Partial Egguirements Customer Class. The holders of Full and Partial Requirements Contracts and the Seattle Retail Distribution System shall be allocated the remaining costs in the Existing Supply Cost Pool. b.

To comply, the Wholesale Customers have to construct adequate storage volume within their individual systems, or sometimes collectively, so as to avoid excessive peak flow withdrawals from the Seattle Transmission Facilities. The Demand Metering Program is established to set performance standards, and to monitor the Wholesale Customer's compliance with this policy. If an individual Water Utility exceeds the prescribed threshold, a "demand charge" is calculated. . Except where other agreements supersede the provisions of this contract, each Water Utility shall be subject to a demand charge based on effective deficient storage, as determined by the peak instantaneous flow rate, and the equivalent financing costs to provide storage. The demand charge rate (i.e., dollars per 1000 gallons of deficient storage) shall be based on the equivalent cost of providing the deficient storage. This rate will be determined as part of each rate study. The Demand Metering Program is charged with implementation of the "demand charge" methodology. It shall be the responsibility of Seattle, in consultation with the Operating Board, to determine the appropriate means to achieve the program's purpose. The options that may be considered range from temporary suspension on a year by year basis to full activation, as described below. There shall be no requirement for Seattle to install demand -metering equipment at each Service Connection in order to assess a demand charge. Seattle may choose to apply "demand metering" selectively to certain parts of the Seattle Transmission Facilities that are designated as "critical" from the standpoint of hydraulic capacity or other operational considerations. Seattle may choose to apply "demand metering" intermittently in various parts of the Seattle Transmission Facilities for the purpose of monitoring for compliance by individual Wholesale Customers or groups of Wholesale Customers on a given line segment. PARTIAL REQUIREMENTS CON'T'RACT CTTY OF RENTON Page 67 EXHIBIT IV OPERATING BOARD STRUCTURE 1. Structure. The Operating Board (or "Board") shall be structured as follows: a. The.Board shall consist of seven (7) members, composed of three members representing Seattle Public Utilities (SPU), three members representing Seattle's Wholesale Customers selected as described below and one independent party selected as set forth below to be a tie-breaker as needed. Board members shall, to the best of their ability, act in the best interests of the Seattle Regional Water Supply System as a whole and shall not represent the interest of a group of utilities or an individual utility. b. The term of each Board position shall commence on January 1 and shall be for four (4) years. Terms of each Board position shall be staggered such that no more than two positions are renewed in any single year. Board members may serve not more than three successive terms. c. Three Board members representing the Wholesale Customers will be selected from the holders of Full and Partial Requirements Contracts . Wholesale Customers will be sorted into three. categories based on utility size. The selected categories will be small, medium and large utilities, which will be made up from approximately equal numbers of holders of Full and Partial Requirements Contracts. Each category of utility may elect, by majority vote (one vote per utility) its representative to the Operating Board. The Board will be recomposed on January 1, 2012 and every 5 years thereafter. d. The seventh member of the Board shall be a person having expertise in the operations of regional water supply systems. Such person shall be selected by majority vote of the other Board members. In the event of a deadlock in selecting the independent representative, the independent Board member shall be selected by Judicial Arbitration and Mediation Services Inc,, of Seattle, Washington or its successor. The seventh member shall not vote on issues coming before the Board unless there is a deadlock in the voting among the other six Board members. The seventh member may nevertheless express his or her opinions in Operating Board discussions. Such member shall have no employment, financial or contractual relationship with Seattle nor any Wholesale Customer or any other actual or apparent conflict of interest in holding this position. 2. Vo. tiny. Except as otherwise provided above, each member of the Board shall have one vote on all matters coming before the Board. Each Board member may appoint an alternate to vote in his or her absence. A quorum of four (4) Board members present shall be required for any vote. Members of the Board may not grant proxies for any vote. 3. Chairperson. The Board shall have a Chairperson who will be selected and have duties as defined below: a, The Chairperson shall be selected at the first regularly scheduled meeting of each new year. PARTIAL REQUMEMENTS CONTRACT CITY OF RENTON Page 68 b. All Chairpersons shall be selected by the Board using a nomination and voting process. c. Nomination for the position of Chairperson shall be taken from Board members, The Chairperson shall be selected based upon the simple majority vote of Board members. Should the Board fail to elect a Chairperson at the first regularly scheduled meeting of the new year, a designated representative from SPU shall be the Acting Chairperson until such time as the Board elects a Chairperson. d. The Chairperson shall have the responsibility to call meetings, determine the agenda and preside over meetings. In the absence of the Chairperson, for whatever reason, a designated representative from SPU shall be the Acting Chairperson for that meeting. The Chairperson shall also act as the spokesperson for the Board and liaison between the Administrator and the Seattle City Council's Committee on Seattle Public Utilities & Neighborhoods or successor committees. 4. Schedule/Procedures. The Board shall adopt a regular meeting schedule and notify all Wholesale Customers of the schedule. The Operating Board may adopt it own internal procedures. The latest edition of Roberts Rules of Order shall, in the absence of agreement by the Operating Board on procedural matters, govern all meetings and votes of the Operating Board. 5. Reporting. The Board will provide reports to the Wholesale Customers and to the Seattle City Council Committee on Seattle Public Utilities & Neighborhoods, or successor City Council committee, on its decisions and recommendations in a timely manner. 6. Responsibilities and Authority of the Board. Where no clear responsibility or authority on an issue is established in this contract the responsibility and authority shall rest with the Seattle City Council. 7. Expenses. The Board shall be authorized to incur reasonable expenses which will be allocated by the Board to either or both of the New Transmission or Supply Cost Pools. PARTIAL REQUMEMENTs CONTRACT CITY OF RENTON Page 69 W t Ai Of an to Pr EXHIBIT VI Calculation of ERUs as a Part of Facilities Charges The ERU Fee is: • the flat debt service payment required to finance the facility providing the ERU over the lesser of (i) the facility life or (ii) the period over which new demand will fully utilize the facility's supply - divided by - • the number of new ERUs of demand expected in each year. Seattle's Average Cost of Debt shall be used as the interest rate in this calculation. In the event that several New Supply Resources are added simultaneously, the facilities may be considered together as providing a total new supply capacity for a total construction cost. Example: A new facility costing $100 million is built with a capacity of 100,000 ERUs. Growth of 5,000 ERUs per year is expected over the next 20 years, so the facility is projected to be supplying its full capacity in 20 years. Were this facility financed over 20 years at 6% interest, the flat annual debt service payment would be $8.7 million. Each ERU would cost 0.02% of this annual amount, or about $1,740. At the time a New Supply Resources is added, the ERU price for this supply shall be calculated, This ERU price shall then be averaged with the then -current ERU Fee. This average shall be weighted by the number of unpurchased ERUs available at the then -current ERU fee and the number of new ERUs being added at the new ERU price. This weighted average shall be the new ERU Fee, and the number of ERUs available at the fee shall be the sum of the unsold ERUs at the previous fee and the ERU capacity of the new facility. Example: 10 years ago, a $100 million facility was constructed that can supply 100,000 ERUs. Growth and demand projections have proven accurate, and now 50,000 ERUs have been purchased, each for $1,740. The facility also has an additional 50,000 ERUs still available at the same price. This year, we construct a facility worth $70 million, with a capacity of 40,000 ERUs. Based on demand projections, this facility (on its own) would be fully utilized in 10 years, and its ERU price is therefore $2,375. The average price of any of the 90,000 available ERUs is therefore $2,022.

For this reason, connection size is only a general indicator of the annual demand placed on water supplies by the establishment.

Water Utility shall use its best efforts to maintain and operate the Independent Sources in order to maintain their annual production capacity as listed above. Water Utility shall provide written notice to Seattle within thirty days of determining that it is not possible or not cost effective to maintain and operate an Independent Source at its listed production levels. Such written notice shall describe the new level of production expected for Independent Source, and shall trigger a charge of Facilities Charges under Section IV.E.8.d. Water Utility shall use its best efforts to cure any interruption of water supply from an Independent Source, shall provide oral notice to Seattle of an interruption of an Independent PARTIAL IREQUMEMENTS CONTRACT CITY OF RENTON Page 89 Source lasting longer than 1 week, and shall provide information on the expected additional demand for water deliveries from Seattle resulting from the interruption. Water Utility shall use its best efforts to minimize the impact of an interruption of an Independent Source on the Seattle Regional Water Supply System by utilizing its other Independent Sources unaffected by the interruption within their operating and maintenance constraints. It is the intent of the parties that the production capacities listed in this Exhibit fairly represent the, production capability of the Independent Sources. In the event that, over a five year period, (i) the actual total annual production, as may be adjusted to reflect a reasonably unforeseeable interruption in Water Utility's Independent Source that lasts a substantial amount of time and is cured within a reasonable time, of the Independent Sources is consistently less than represented in this Exhibit, and (ii) the annual deliveries of water to Water Utility by Seattle are consistently increasing, the capacities of the Independent Sources listed in this Exhibit shall be reduced, and the reduction shall be deemed a permanent interruption and trigger a charge of Facilities Charges under Section IV.E.8.d.

DEVELOPMENT SCHEDULE BEGINNING DATE =PiATION DATE DATE COMPLETE APPLICATION OF WATER TO BE MADE Started PROVISIONS AND RECOMMENDATIONS The request for 1050.0 gallons per minute is granted with an annual quantity of 1680.0 acre-feet per year for municipal supply. Applicant is advised that notice of proof of appropriation of water (under which final certificate of water right issues) should not be filed until the permanent diversion facilities have been installed together with a mainline system capable of delivering the recommended quantity of water to an existing or proposed distri- bution system within the area to be served. Use of the waters to he appropriated under this application will be for a public water supply. State Board of Health rules require every owner of a public water supply to obtain written approval from the Assistant Secretary, Division of Health prior to any new construction or alterations of a public water supply. The appli- cant is advised to contact the Washington State Division of Health, Public health Building No. 4, Thurston Airdustrial Center, Olympia, with regard to the need for compliance. "A suitable measuring device shall be installed and maintained in accordance with WAC 508-64-020 through WAC 508-64-040." (Installation, operation and maintenance requirements attached hereto.) It is noted that the well site and/or water transmission facilities are not wholly located upon the land owned by the applicant. Applicant is, accordingly, advised that the issuance of permit by this Department for appropriation of the waters in question does not convey a right of access to, or other right to use, land which the applicant does not legally possess. Obtainment of such right is a private matter between applicant and owner of that land. Copy(ies) of easement agreement(s) must be furnished this Department prior to issuance of Certificate of Water Right. Additionally, the permit when issued shall carry the following provision. "Nothing in this permit shall be construed as excusing the permittee from compliance with any applicable federal, state, or local statutes, ordinances, or regulations including those administered by local agencies under the Shoreline Management Act of 1971."

TlAs application is for 2.3 c.f.s. from Springbrook Creek for municipal water supply. A council man for the City of Renton took me out and explained this application. I find that tine City of Renton wishes to increase their supply from this creek. No use is made of the creek other than possibly for stock purposes. Just below the point of diversion there is a county road crossing which causes a fall of about 18 or 20 feet. There is 0.94 c.f.s. or 607,616 gallons per day flovOing over the weir at this point of diversion. There is also seepage and leakage at the dam of possibly one -.half this amount, or 1.5 c.f.s. available at the lower point of diversion. I find public nater available and the purpose to whic`, it is to be applied a beneficial use. A permit should issue subject to existing rights. CLARENCE E.

RENTON, WASH. 98055 206 235-2569 August 10, 1987 Apparently you or your son inferred that the city of Renton is required to flow 2.5 cubic feet of water into Springbrook Creek and that we were not doing it. I submit the following for your information: 1. Certificate of Water Right, dated December 17, 1930, for surface water of 2.3 cubic feet per second or 1050 gallons per minute. 2. Certificate of Additional Water Right, for ground water, dated May 3, 1973, in the amount of 1050 gallons per minute. It should be noted, that neither of these certificates require flow in Springbrook Creek. At one time the City of Renton applied for additional surface water rights under application No. 19590 (on April 14, 1966) which required flow in Springrook Creek, but this application was cancelled on June 7, 1971. Also attached are copies of your water right, Certificate of Surface Water Right No. 3421, which was originally granted to Halvor Fluen in November of 1949. This water right was in the amount of .40 cubic feet per second (3 gallons per second, or 180 gallons per minute) from Springbrook Creels. An additional amount, .20 cubic feet, was given for other springs on your property. A Certificate of Change of Place of Use of Water was granted on January 18, 1957 through Certification of Change form No. 489. August 10, 1987 Don Gallagher Page 2 From the above rights it appears that you have 180 gallons per minute water rights from Springbrook Creek. If you have any other water rights, surface or ground water, please send us a copy of them. At the present time the City of Renton is taking approximately 540 gallons per minute from the Springs. This is approximately one-half of our allotted right under the 1930 water right. For some reason the Springs have not produced the water volumes that they once did. As long as the City is not short of water supplies from its other sources, the City has, and will, allow additional flows down the creek to help you. This is done in the form of a good neighbor policy. These additional flows are not meant to imply that the Utility views the granting of them as a requirement. Your earliest response to this letter would be appreciated. Very truly yours, Richard C.

Complete Corn plete In use REPORT BACKGROUND This application for change was received from the City of Renton to change the point of withdrawal (replace well) for Water Ri ht Certificate No. 886-D which issued for 1,040 gallons per minute (GPM); 1,676 acre-feet per year (AF/ -YR) for Municipal supply from the City of Renton's Well No- 1. This Certificate has a priority date of January 1944 based on a Declaration of Claim No. 816 (see list under GENERAL INFORMATION below for other changes this source). Legal notice was published in the Valley Daily News on September 30 and October 7, 1987. No protests were received. INVESTIGATION Investigation consists of office research which includes review of water right records, well pumping data, consultant's reports and Renton's Conservation and Comprehensive Water System Plans. Numerous site visits were made, including on-site observations during aquifer tests. Also, Ecology staff attended several meetings which involved this and other Renton applications. General Information This is the first of five Applications For Change of Water Right relating to three wells located near the center of the City of Renton in Liberty Park. Wells No. 1 & 2 were drilled and put to use in 1944. Withdrawal rates in these two wells were increased in 1966, at which time Well No. 3 was drilled. As a result, Well No. 1 has two certificated rights with instantaneous withdrawals totaling 2,000 GPM; Well No. 2 has two rights totaling 3,000 GPM, and Well No- 3 has one right for 1,600 GPM. All five rights total 6,600 GPM (see the following listing). Cert.No. Well No. Priority GPM AF/YR 886-D* 1 January 1944 1,040 1,676 5838-A 1 April 14, 1966 960 1,536 Supplemental 887-D 2 January 1944 1,040 838 5836-A 2 April 14, 1966 1,960 3,136 Supplemental 5835-A 3 April 14, 1966 1,600 2,560 Supplemental 6,600 Total *Identifies this application By 1987 wells 1 and 2 needed to be replaced as casings were showing signs of potential collapse and surface seals did not meet current standards. Wel] 3 was located next to a gas station and needed to be relocated for a greater degree of protection from contamination. Plans called for the replacement wells to be put under one roof and pumping rates for each well equalized to increase overall system efficiency. Therefore, in addition to replacing the three wells, Renton also requested that their water rights be changed to allow equal pumping from each well. Permitting this equalization can be accomplished by changing the point of withdrawal on Certificate No. 5836-A from old Well 2 to three new points of withdrawal from new wells 1, 2 & 3. This is an acceptable water right change as all wells will tap the sante source of water in a confined aquifer within the Cedar River Basin and will be located within the same 114 section and drilled to similar depths. Also under this change the place of use will be updated to include vested interties approved by Ecology (Bucknell letter June 22, 1992). R0' APPLICATION FOR CHANGE OF .ATER RIGHT . -2- No. 886-D Report Continued 72 hour aquifer test was perforated on .lune 24, 25 and 26, 1987. Both old and new wells were used to stress iquifer_ Wells were pumped at 11,400 GPM for 24 hours then increased to 14,700 GPM for 25 hours (total antaneous withdrawal of all five certificates equals 6,600 GPM). Renton hired the USGS to measure Cedar River flows both above and below the well sites, during and following the test. The consultant's hydrogeologic profile shows approximately 15 feet of drawdown occurred at the main well heads, 5 feet within 500 feet and full recovery within eight hours. No effect could be treasured to flows ill the Cedar River. On September 21, 1987, a Temporary Permit was issued to remain in effect during the pendency of the applications. Anolication Snecific Information This report is specific to Water Right Certificate No_ 886-D with a priority date of January 1944. This right authorizes a withdrawal of 1,040 GPM and 1,676 AFfYR from Renton's Well No. 1 for a Municipal Supply. New well No. 1 was drilled in March 1987 to a depth of 96'. It is cased to 57' and screened from 57' to 91'. A cement grout surface seal extends to 22. The well was pump tested by the driller on March 27, 1987 at 2,000 GPM with four feet of drawdown after four hours of pumping. The following relates to the original and replacement Well No. 1 OLD WELL # 1 82' deep; 26" diameter SWL 22' - ground surface 125' North & 985' West of Center of Section 17 within SE'/< NW'/< Section 17 Township 23 north Range 5 east Willamette Meridian but 60' south and 40' east NEW WELL # 1 96' deep; 24" diameter SWL 27' - top of well 65' North & 945' West of Center of Section 17 Sarre legal as old Well No_ I A review of Ecology's water right files and the drillers' Water Well Report files show that other water rights in this area are those of the applicant, the City of Renton. Consistency With Plans, Policies & Laws Renton has an updated Water Conservation Plan (1990) and a Comprehensive Water System Plan (1.992). Moir detail on these and a complete listing of all Renton's water rights and water allocations can be found in files G1 -24781P, GI -25396P and G1 -25397P on permits issued for wells No. ll & 17. Until Regional Water Plans are established as set forth by the Chelan Agreement, Ecology is developing the Interim_ Solutions to Public Water Supply Needs policy. These solutions involve considering alternatives in Heti of developing new water sources. As this application involves a change in the point of withdrawal (replacement well) and a change in place of use (intertie) and no new water source, it is consistent with this Interim Solutions policy. The Instream Resource Protection Progam am (1RPP) for the Cedar!Sarn nantish Basin was adopted in Septeruber, 1979 under Chapter 173-508 WAC which identified instream flow values for the Cedar River. The Seattle Water Department and others have long contended that Renton's wells are in hydraulic continuity with the river. Renton and their consultants, RH2 Engineerin{o, contend that the confined acluifer in this 4ffea ntnves sown inter the old Slack River channel and into the lower Duwamish and Elliott Bay. As the rights on these wells preceded the regulation, none of this should be relevant except that Seattle's claimed right from the river precedes Renton's certificates on their wells. Also, Renton has expressed interest in obtaining additional water from these wells. 72 hour aquifer test described earlier in this report was intended to first, quantify the capacity of the aquifer ,as also done in the attempt to dismiss the false assertions that Renton's wells sucked the river day w,,enever their pumps kicked on. Also, they hoped to prove their theory on directional movement of ground water in this area. Without monitoring ground water in the old Black River channel during the test, Renton's theory remains only a theory. 'rhe test did show, however, that pumping the aquifer at double certificated quantities had no measurable effect on the river. Report Continued This application is consistent with the State Surface and Ground Water Codex Chapters 90.03 and 90.44 RCW. as described below. This change meets requirements of RCW 90,03.383 (Interties), in that by letter (Bucknell, June 22, 1992), Ecology accepted Renton's interties that had been in place prior to January 1, 1991 as vested. Changing the place of use to these existing certificates will complete the required process. This change also meets requirements defined in RCW 90.44.100 for approving an amendment to a certificate for a change in the point(s) of withdrawal in that-. 1. The new well taps the same body of public ground water as the original well. 2. The original well has been properly abandon. 3. The changes do not enlarge the right conveyed by the original certificate. 4. Existing rights will not be impaired. CONCLUSION In accordance with chapters 90.03 and 90.44 RCW, I find that the certificate holder has perfected this right by putting the water to full beneficial use, This change will not enlarge the right conveyed on the original certificate, nor will the granting of this change impair existing rights or be detrimental to the public welfare. Therefore, a superseding certificate should be issued subject to existing rights and indicated provisions. RECOMMENDATIONS A superseding certificate should be issued as original for 1,040 GPM and 1,676 Al~/YR; with the same priority date of January, 1944; with the change being in the point of withdrawal (new well) and the place of use (current service area including interties) and subject to the following recommendations and provisions: An approved measuring device shall be installed and maintained in accordance with RCW 90.03.360, WAC 508-64-020 through 508-64-040 (Installation, operation and maintenance requirements enclosed).

Consistency With Plans, Policies & Laws Renton has an updated Water Conservation Plan (1990) and a Comprehensive Water System Plan (1992). More detail on these and a complete listing of all Renton's water rights and water allocations can be found in files G1-2478IP, G1 -25396P and GI -25397P on permits issued for wells Noll & 17. Until Regional Water Plans are established as set forth by the Chelan Agreement, Ecology is developing the Interim Solutions to Public Water Supply Needs policy. These solutions involve considering alternatives in lieu of developing new water sources_ As this application involves a change in the point of withdrawal (replacement well) and a change in place of use (interlie) and no new water source, it is consistent with this Interim Solutions policy. The Instream Resource Protection Program (IRPP) for the Cedar/Sammamish Basin was adopted in September, 1979 under Chapter 173-508 WAC which identified instream flow values for the Cedar River_ The Seattle Water Department and others have long contended that Renton's wells are in hydraulic continuity with the river. Renton and their consultants, RI 12 Engineering, contend that the confined aquifer in this area moves south into the old Black River channel and into the lower Dllwamish and Elliott Bay. As the rights on these wells preceded the regulation, none of this should be relevant except that Seattle's claimed right from the river precedes ton's certificates on the it wells. Also Renton haus expressed interest in obtaining additional water from these The 72 hour aquifer test described earlier in this report was intended to first, quantify the capacity of the aquifer but was also done in the attempt to dismiss the false assertions that Renton was sucking the river dry whenever their pumps kicked on. Also, they hoped to prove their theory an directional movement of ground water in this Black River channel during the test, Renton's theory remainsmonitoring ground water in tite old Report -Continued only a theory. The test did show, however, that pumping the aquifer at double certificated quantities had no measurable effect on the river. This application is consistent with the State Surface and Ground Water Code, Chapters 90.03 and 90.44 RCW. as described below. This change meets requirements of RCW 90.03.383 (Interties), in that by letter (Bucknell, June 22, 1992), Ecology accepted Renton's interties that had been in place prior to January 1, 1991 as vested. Changing the place of use to these existing certificates will complete the required process. This change also meets requirements defined in RCW 90.44.100 for approving an amendment to a certificate for a change in the point(s) of withdrawal in that: 1. The new well taps the same body of public ground water as the original well. 2. The original well has been properly abandon. 3. The changes do not enlarge the right conveyed by the original certificate. 4. Existing rights vdlI not be impaired_ CONCLUSION In accordance with chapters 90.03 and 90.44 RCW, I find that the certificate holder has perfected this right by putting the water to full beneficial use. This change will not enlarge the right conveyed on the original certificate, nor will the granting of this change impair existing rights or be detrimental to the public welfare. Therefore, a superseding certificate should be issued subject to existing rights and indicated provisions. A superseding certificate should be issued as original for 960 GPM and 1.536 AFNR supplemental to existing rights and with the same priority date of April 14, 1966. This change includes the point of withdrawal (new well) and the place of use (current service area including interties) and is subject to the following recommendations and provisions: An approved measuring device shall be installed and maintained in accordance with RCW 90.03.360, WAG 508-64-020 through 508-64-040 (Installation, operation and maintenance requirements enclosed).

Complete Complete In use REPORT BACKGROUND This application for change was received from the City of Renton to change the point of withdrawal (replace well) for Water Right „Certificate No. 887-D which issued for 1,040 gallons per minute (GPM); 838 acre-feet per year (AF/ -YR) for Municipal supply from the City of Renton's Well No. 1. This Certificate has a priority date of January 1944 based on a Declaration of Clairn No. 817 (see list under GENERAL INFORMATION below for other changes this source). Legal notice was published in the Valley Daily News on September 30 and October 7, 1987. No protests were received. INVESTIGATION Investigation consists of office research which includes review of water right records, well pumping data, consultant's reports and Renton's Conservation and Comprehensive Water System Plans. Numerous site visits were made, including on-site observations during aquifer tests. Also, Ecology staff attended several meetings which involved this and other Renton applications. General Information This is one of five applications for changes to water rights relating to three wells located near the center of the City of Renton in Liberty Park. Wells No. 1 & 2 were drilled and put to use in 1944. Withdrawal rates in these two wells were increased in 1966 at which time Well No. 3 was drilled. As a result, Well No. I has two certificated rights with instantaneous withdrawals totaling 2,000 GPM.; Well No. 2 has two rights totaling 3,000 GPM and Well No. 3 has one right for 1,600 GPM. All five rights total 6,600 GPM (see the following listing). Cert.

Well 3 was located next to a gas station and needed to be relocated for a greater degree of protection from contamination. Plans called for the replacement wells to be put under one roof and pumping rates for each well equalized to increase overall system efficiency. Therefore, in addition to replacing the three wells, Renton also requested that their water rights be changed to allow equal pumping from cacti well. Permitting this equalization can be accomplished by changing the point of withdrawal on Certificate No. 5836-A from old well 2 to three new points of withdrawal from new wells 1, 2 & 3_ This is an acceptable water right change as all wells will tap the same source of water in a confined aquifer within the Cedar River Basin and will be located within the same 1/4 section and drilled to similar depths. Also under this change the place of use will be updated to include vested interties approved by Ecology (Pucknell letter June 22, 1992). Report Continued " 72 hour aquifer test was performed on June 24, 25 and 26, 1987. Both old and new wells were used to stress quifer. Wells were pumped at 11,400 GPM for 24 hours then increased to 14,700 GPM for 25 hours (total antaneous withdrawal of all five certificates equal 6,600 GPM). Renton hired the USGS to measure Cedar River flows both above and below the well sites, during and following the test. The consultant's hydrogeologic profile shows approximately 15 feet of drawdown occurred at the main well heads, 5 feet within 500 feet and full recovery within eight hours. No effect could he measured to flows in the Cedar River. On September 21,1987 a Temporary Permit was issued to remain in effect during the pendency of the applications. Application Specific Information This report is specific to Water Right Certificate No. 887-D with a priority date of January 1944. This right authorizes a withdrawal of 1,040 GPM and 838 AF/YR from Renton's Well No. 2 for a Municipal Supply. New Well No. 2 was completed on June 21, 1987 to a depth of 74'. It is cased to 50' and screened from 50' to 70'. A cement grout surface seal extends to 22. The well was pump tested by the driller on April 8, 1987 at 2,325 GPM with five feet of drawdown after four hours of pumping. The following relates to the original and replacement Well No. 2 OLD WELL # 2 NEW WELL # 2 82' deep; 26" diameter 74' deep; 24" diameter SWL 22' - ground surface SWL 24' - top of well 130' north & 1,000' west of 70' North & 970' West of center of Section 17 within center of Section 17 SE%a NW%a Section 17 Same legal as old Well # 1 Township 23 north Range 5 east but 60' south and 30' east Willamette Meridian A review of Ecology's water right files and the drillers' Water Well Report files show that other water rights in this area are those of the applicant, the City of Renton. Consistent With Plans Policies .& Laws Renton has an updated Water Conservation Plan (1990) and a Co reprehensive Water_System Plan (1992). More detail on these and a complete listing of all Renton's water rights and water ailocmions can he found in files G1 -24781P, G1 -25396P and G3-253971` on permits issued for wells Noll & 17. Until Regional Water Plans are established as set forth by the Chelan Agreement, Fcology is developing the Interim Solutions to Public Water Supper Needs policy. These solutions involve considering alternatives in lien of developing new water sources. As this application involves a change in the point of withdrawal (replacement well) and a change in place of use (intertie) and no new water source, it is consistent with this Interim Solutions Policy. The lnstream Resource Protection Program (IRPP) for the CedarlSammantish Basin was adopted in September, 3979 tinder Chapter 173-508 WAC which identified instrearn flow values for the Cedar River. The Seattle Water Department and others have long contended that Renton's wells are in hydraulic continuity with the river. r. t. nton and their consultants, R142 Engineering, contend that the confined aquifer in this area moves south into the old Black River channel and into the lower Duwaniish and Elliott flay. As the rights on these wells preceded the regulation, none of this should be relevant except that Seattle's claimed right from the river precedes Renton's certificates on their wells. Also Renton has expressed interest in obtaining additional water from these wells. The 72 hour aquifer test described earlier in this report was intended to first, quantify the capacity of the aquifer was also done to the attempt to dismiss the false assertions that Renton's wells suck the river dry whenever pumps kicked an. Also, they hoped to prove their theory on directional movement of ground water in this a,ea_ Without monitoring ground water in the old Slack River channel during the test, Renton's theory remains only a theory. The test did show, however, that pumping the aquifcr at certificated quantities has no measurable effect on the river_ Report Continued This application is consistent with the State Surface and Ground Water Code Chapters 98.03 and 90.44 RCW, as described below, This change meets requirements of RCW 90.03383 (Intertles), in that by letter (Bucknell, June 22, 1992), Ecology accepted Renton's interties that had been in place prior to January 1, 1991 as vested. Changing the place of use to these existing certificates will complete the required process. This change also meets requirements defined in RCW 90.44.100 for approving an amendment to a certificate for a change in the point(s) of withdrawal in that: 1. The new well taps the same body of public ground water as the original well. 2. The original well has been properly abandon. 3. The changes do not enlarge the right conveyed by the original certificate. 4. Existing rights will not be impaired. CONCLUSION In accordance with chapters 90,03 and 90.44 RCW, I find that the certificate holder has perfected this right by putting the water to full beneficial use. This change will not enlarge the right conveyed on the original certificate, nor will the granting of this change impair existing rights or be detrimental to the public welfare. Therefore, a superseding certificate should be issued subject to existing rights and indicated provisions. RECOMMENDATIONS A superseding certificate should be issued as original for 1,040 GPM and 838 AF/YR; with the same priority date of January, 194$; with the change being in the point of withdrawal (new well) and the place of use (current service area including interties) and subject to the following recommendations and provisions: An approved measuring device shall be installed and maintained in accordance with RCW 90.03.360, WAC 508-64-020 through 508-64-040 (Installation, operation and maintenance requirements enclosed).

Well 3 was located next to a gas station and needed to be relocated for a greater degree of protection from contamination. Plans called for the replacement wells to be put under one roof and pumping rates for each well equalized to increase overall system efficiency. Therefore, in addition to replacing the three wells, Renton also requested that their water rights be changed to allow equal pumping from each well. Permitting this equalization can be accomplished by changing the point of withdrawal on Certificate No. 5836-A from old Well 2 to three new points of withdrawal to new wells 1, 2 &. 3 (see report for 5836-A for more information). This is an acceptable water right change as all wells will tap the same source of water in a confined aquifer within the Cedar River Basin and will be located within the same 114 section and drilled to similar depths. Report Continued Also under this change, the place of use will be updated to include vested interties approved by Ecology nell June 22, 1992). A 72 hour aquifer test was performed on June 24, 25 and 26, 1987. Both old and new wells were used to stress the aquifer. Welts were pumped at 11,400 GPM for 24 hours then increased to 14,700 GPM for 25 hours (total instantaneous withdrawal of all five certificates equal 6,600 GPM). Renton hired the USGS to measure Cedar River flows both above and below the well sites, during and following the test. The consultant's hydrogeologic profile shows approximately 15 feet of drawdown occurring at the main well heads, 5 feet within 500 ft. and full recovery within eight hours after pump shut -down. No measurable effect occurred to flows in the Cedar River_ On September 21, 1987,. a Temporary Permit was issued to remain in effect during the pendency of the applications. ADplication Specific Information This report is specific to Water Right Certificate No. 5835-A with a priority date of April 14, 1966 from Well No. 3 for a Municipal Supply. This right authorizes a withdrawal of 1,600 GPM and 2,560 AF/YR supplemental to Renton's other rights. Old Well 3 will not be abandon but maintained as a contaminant interceptor well, but also will be kept operational as an emergency standby source. New Well No. 3 was drilled in March and April 1987 to a depth of 84', completed to 76', cased to 52' and screened from 52' to 72'. A cement grout surface seal extends to 22'. The well was pump tested by the driller on May 28, 1987 at 2,300 GPM with five feet of drawdown after four hours of pumping.

Consistencv With Pians, Policies & Laws Renton has an updated Water Conservation Plan (1990) and a Comprehensive Water System Plan (1992). More detail on these and a complete listing of all Renton', water rights and water allocations can be found in files GI -24781P, G1 -25396P and G1 -25397P on permits issued for wells Noll & 17. Until Regional Water Plans are established as set forth by the Chelan Agreement, Ecology is developing the Interim Solutions to Public Water Supply Needs policy. These solutions involve considering alternatives in lieu of developing new water sources. As this application involves a change in the point of withdrawal (replacement well) and a change in place of use (intertie) and no new water source, it is consistent with this Interim Solutions policy. The Instream Resource Protection Program (IRPP) for the Cedar/Sammamish Basin was adopted in September, 1979 under Chapter 173-508 WAC which identified insteam flow values for the Cedar River. The Seattle Water Department and others have long contended that Renton's wells are in hydraulic continuity with the river. Renton and their consultants, RH2 Fngineering, contend that the confined aquifer in this area moves south into th d Black River channel and into the lower Duwamish and Elliot Bay. As the rights on these wells preceded t ulation, none of this should be relevant except that Seattle's claimed right from the river precedes Rt n's certificates on their wells. Also Renron has expressed interest in obtaining additional water from these; wells. The 72 hour aquifer test described earlier in this report was intended to first, quantify the capacity of the aquifer but was also done in the attempt to dismiss the false assertions that Renton's wells suck the river dry whenever Report Continued their pumps kick on. Also, they hoped to prove their theory on directional movement of ground water in this area_ Without monitoring ground water in the old Black River Channel during the test, Renton's theory remains only a theory. The test did show, however, that pumping the aquifer at double certificated quantities had no measurable effect an the river. This application is consistent with the State Surface and Ground Water Code, Chapters 90.03 and 90.44 RCW. as described below. This change meets requirements of RCW 90.03.383 (Interties), in that by letter (Bucknell, .lune 22, 199:?), Ecology accepted Renton's interties that had been in place prior to January 1, 1991 as vested. Changing the place of use to these existing certificates will complete the required process. This change also meets requirements defined in RCW 90.44.100 for approving an amendment to a certificate for a change in the point(s) of withdrawal in that: 1. The new well taps the same body of public ground water as the original well. 2. The original well will be maintained as a contaminant interceptor and may be used as an emergency backup source. 3. This will not enlarge the right conveyed by the original certificate. 4. E3dsting rights will not be impaired. CONCLUSION In accordance with chapters 90.03 and 90.44 RCW, i find that the certificate holder has perfected this right by putting the water to full beneficial use. This change will not enlarge the right conveyed on the original certificate, nor will the granting of this change impair existing rights or he detrimental to the public welfare. 'Therefore, a superseding certificate should be issued subject to existing rights and indicated provisions. RECOMMENDATIONS A superseding certificate should be issued as original for 1,600 GPM and 2,560 AF/YR supplemental to existing; rights and with the same priority date of April 14, 1966. This cbange includes the point of withdrawal (new we[]) and the place of use (current service area including iterties) and is subject to the following recommendations and provisions: Original Well No. 3 will be maintained primarily as a contaminant intercepter and, should other systems fail, may be used as an emergency backup after notifying Ecology_ An approved measuring device shall be installed and maintained in accordance with RCW 90.03.360, WAC 508-64-020 through 508-64-040 (Installation, o oration and maintenance re uirements enclosed).

This change is from the City's Liberty Park Well No. 2 to three new withdrawal points - new wells 12 & 3. This, the second right issued on this well, issued for 1,960 gallons per minute (GPM); 3,136 acre-feet per year (AF!YR) supplemental to Renton's other rights for Municipal supply (see list under GENERAL INFORMATION). Legal notice was published in the Valley Daily News on September 30 and October 7, 1987. No protests were received. INVESTIGATION Investigation consists of office research which includes review of water right records, well pumping data, consultant's reports and Renton's Conservation and Comprehensive Water System Plans. Numerous site visits were made, including on-site observations during aquifer tests_ Also, Ecology staff attended several meetings which involved this and other Renton applications. General Information This is one of five Applications For Change Of Water Right relating to three wells located near the center of the City of Renton in Liberty Park. Wells No. 1 & 2 were drilled and put to use in 1944_ Withdrawal rates in these two wells were increased in 1966, at which time Well No. 3 was drilled. As a result, Well No. 1 has two certificated rights with instantaneous withdrawals totaling 2,000 GPM; Well No. 2 has two rights totaling 3,000 GPM, and Well No_ 3 has one right for 1,600 GPM. All five rights total 6,600 GPM (see the following listing). Cert.

Well 3 was located neat to a gas station and needed to be relocated for a greater degree of protection from contamination. Plans called for the replacement wells to be put under one roof and pumping rates for each well equalized to increase overall system efficiency. Therefore, in addition to replacing the three wells, Renton also requested that their water rights he changed to allow equal pumping (2,200 GPM) from each well_ Permitting this equalization can be accomplished by changing the point of withdrawal on this certificate (No. 5836-A) from old Well 2 to three new points of withdrawal to new wells 1, 2 & 3 (see discussion following under APPLICATION SPECIFIC INFORMATION). This change is possible, as all wells will tap the same source of water in a confined aquifer within the Cedar River Basin and will be located within the same. 1/4 section and drilled to similar depths. Report Continued Also under this change, the place of use will be updated to include. vested interties approved by Ecology -nell June 22, 1992). A rL hour aquifer test was performed on June 24, 25 and 26, 1987. Both old and new wells were used to stress the aquifer. Wells were pumped at 11,400 GPM for 24 hours then increased to 14,700 GPM for 25 hours (total instantaneous withdrawal of all five certificates equal 6,600 GPM). Renton hired the USGS to measure Cedar River flows both above and below the well sites, during and following the test. The consultant's hydrogeologic profile shows approximately 15 feet of drawdown occurred at the main well heads, 5 feet within 500 feet and full recovery within eight hours. No effect could be measured to flows in the Cedar River. On September 21, 1987, a Temporary Permit was issued to remain in effect during the pendency of the applications. Application Specific Information This report is specific to Water Right Certificate No. 5836-A with a priority date of April 14, 1966 from Liberty Park Well No. 2 for a municipal supply. This right authorizes a withdrawal of 1,960 GPM and 3,136 AE/YR, supplemental to Renton's other rights. Old well No. 2 has two rights totaling 3,000 GPM. To equalize the pumping between the three new wells at 2,200 GPM, as requested, the certificated withdrawal from this right, 5836-A, for 1,960 GPM, will need to be split between the three new wells as described below: 1. 200 GPM to new Well No. 1, located 60' south and 50' east of the original Well No. 2; 2. 1,160 GPM to new Well No. 2, located 60' south and 30' east of the original Well No. 2; 3. 600 GPM to new Well No. 3, located 50, south and 10' east of the original Well No. 2; New wells 1, 2 & 3 were completed in June 1987. Each is surface sealed with cement grout to 22'.

This Certificate has a priority date of February 18, 1953 (see discussion and list tinder GENERAL. INFORMATION below for other rights and changes from this source). Legal notice was published in the ValleDaily _ News on September 30 and October 7, 1987. No protests were received. IMTSTYGATION Investigation consists of office research which includes review of water right records, well pumping data, consultant's reports and Renton's Conservation and Comprehensive Water System Plans. Site visits and meetings occurred, involving this and other Renton applications. General Information pplication For Change Of Water Right relates to a well located in the north end of the City of Renton jt ast of I-405 and approximately ane -quarter mile east of Lake Washington in the Kennydale area. Land surface elevation at the well site is 236' above mean sea level. This well (referenced as ex-Kennydale Well # 1) was certificated as Renton Well No. 5 with priority date February 18, 1953. Withdrawal rates from this well were increased in 1966. As a result, this well has two certificated rights (see the following listing). Cert. No. Priority GPM AF/YR 3591-A'" February 18, 1953 1,300 2000 5834-A April 14, 1966 200 320 Total 1,500 2320 *Identifies this application Also under this change the place of use will be updated to include vested interties approved by Ecology (Bucknell letter June 22, 1992). Original Well No. 5 was completed on September 28, 1953 at a depth of 386' with a 20" diameter casing. Renton's 1992 Comprehensive Water System Plan states that this well operated satisfactorily from 1953 to 1959 when it began producing sand. The plan also states that in 1965, when water quality complaints on taste and odor were received, the use of this well was discontinued. Our records show, however, that Renton filed for a second right, to increase pumping, in 1966. In discussions with Mr. Ron Olsen, Renton's Utility Engineer, it appears the well was not decommissioned but maintained can standby. Then when a later 1965 study showed the need and the capability of the well exceeding that of the right, Renton filed and perfected this additional right. Water Well Report records support that the original well was not decommissioned until 1988 when the well was permanently and properly abandon. I gust 31, 1987 Ecology issued a Temporary Permit to remain in effect during the pendency of the a,.. a0ons. During that time, Ecology issued Temporary Permits for drilling, developing and use. New Well No. 5 was completed on March 3, 1988 to a depth of 407'. The casing from + 2.5' to 65' is 20" diameter; from + 2.5' to 285' is 16" diameter and from 277' to 407' is 14" diameter, Stainless steel screens are anF F(G APPI V-ATION FOR r HANC;F n1 ATFR RIGHT -7- No. 3591-A Report Continued located in the bottom 104' of the well. The cement grout surface seal extends from the surface to 100'. The well was pump tested by CI -12M HILI. on March 16, 1988 at 1,250 GPM with 62,4' of drawdown after 48 hours of pumping. The following relates to the original and replacement Well No. 5: OLD WELL # 5 NEW WELL # 5 386' deep; 22" diameter 407' deep; 14" diameter SAIL 134.8' - ground surface SWL 137.75' - top of well 1265' north & 136' west of 1255' north & 134' west of center of Section 5 within center of Section 5 SEI/4 NW'/4 Section 5 Same legal as old Well # 5 Township 23 north Range 5 east but 10' south and 2' east Willamette Meridian The original well was properly abandon on April 12, 1988 as identified on the Abandonment Water Well Report available in Ecology files. A review of Ecology's water right files and the drillers' Water Well Report files located no other water rights in the area. Consistencv With Plans. Policies & Laws Renton has an updated Water Conservation Plan (1990).and a Comprehensive Water System Plan (1992). More detail on these and a complete listing of all Renton's water rights and water allocations can be found in files G1 -24781P, G1 -25396P and GI -25397P on permits issued for wells No. 11 & 17. Until Regional Water Plans are established as set forth by the Chelan Agreement, Ecology is developing the Interim Solutions to Public Water Supply Needs policy. These solutions involve considering alternatives in lieu of developing new water sources. As this application involves a change in the point of withdrawal (replacement well) and a change in place of use (intertie) and no new water source, it is consistent with this Interim So[utintis policy. The Instrearn Resource Protection Program (IRPP) for the Cedar/Sanimantish Basin was adopted in September, 1979. Under Chapter 173-508 WAC, Lake Washington (including ground water in continuity with the lake) is closed to further consumptive use. As this use from Well No. 5 was certificated prior to enactment of this code, and as the drilling of this replacement well (10' distant from original well) will not increase the potential for hydraulic continuity, this change is acceptable under the regulation. This application is consistent with the State Surface and Ground Water Code Chapters 90.03 and 90.44 RCW, as described below. This change meets requirements of RCW 90.03.383 (Interties), in that by letter (Bucknell, ,lune 22, 19E2), Ecology accepted Renton's interties that had been in place prior to January 1, 1991 as vested. Changing the place of use on this existing certificate completes the required process. This change also meets requirements defined in RCW 90.44.100 for approving an amendment to a certificate for a change in the point(s) of withdrawal in that: 1. The new well taps the same body of public ground water as the original well. 2_ The original well has been properly abandon. 3. The changes do not enlarge the right conveyed by the original certificate. 4. Existing rights will not be impaired. CONCLUSION In accordance with chapters 90.03 and 90.44 RCW, 1 find that the certificate holder has perfected this right by putting the water to full beneficial use. This change will not enlarge the right conveyed on the original certificate, nor will the granting of this change impair existing rights or be detrimental to the public welfare. Therefore, a superseding certificate should be issued subject to existing rights and indicated provisions. Report Continued RECOMMENDATIONS ,rseding certificate should be issued as original for a withdrawal of 1,300 GPM and 2,000 AF/YR- with th- .:ame priority date of February 18, 1953; with the change being in the point of withdrawal (new well) and the place of use (current service area including interties); and the right is subject to the following recommendations and provisions: An approved measuring device shall be installed and maintained in accordance with RCW 90.03.360, WAC 508- 64-020 tbrnugh 508-64-040 (Installation. operation and maintenance requirements enclosed.

Our records show, however, that Renton filed for this right to increase pumping in April, 1966 and put that water to full use on December 1, 1966. In discussions with Mr. Ron Olsen, Renton's Utility Engineer, it appears the well was not decom.ntissioned but maintained on standby. Then when a later 3965 study showed the need for water and the capability of this well exceeding that of the right, Renton filed and perfected this additional right. Water Well Report records support that the original well was not decommissioned until I988 when the well was perm.,inently and properly abandon_ t gust 31, 1987 Ecology issued a Temporan. Permit to remain in effect during the pendency of the appacations. During that time, Fcology issued Temporary Permits for drilling, developing and use. New Well No- 5 was completed on March 3, 1988 to a depth of 407'. The casing from + 2.5' to 65' is 20" diameter; from + 2.5' to 285' is 16" diameter and froin 277' to 407' is 14" diameter. Stainless steel screens are Report Continued located in the bottom 100' of the well. The cement grout surface sea] extends from the surface to 100'. The well was pump tested by CH2M HILL on March 16, 1988 at 1.250 GPM with 62.4' of drawdown after 48 hours of pumping. The following relates to the original and replacement Well No. 5: OLD WELL # 5 NEW WELL # 5 386' deep; 22" diameter 407' deep-, 14" diameter SWL 134.8' - ground surface SWL 137.75' - top of well 1265' north & 136' west of 1255' north & 134' west of center of Section 5 within center of Section 5 SE'/, NW'/, Section 5 Same legal as old Well # 5 Township 23 north Range 5 east but 10' south and 2' east Willamette Meridian The original well was properly abandon on April 12, 1988 as identified on the Abandonment Water Well Report available in Ecology files. A review of Ecology's water right files and the drillers' Water Well Report files located no other water rights in the area. Consistenev With Pians, Policies & Laws Renton has an updated Water Conservation Pian (1490) and a Comprehensive Water System Plan (1992). More detail on these and a complete listing of all Renton's water rights and water allocations can be found in files G1 -24781P, 01-25396P and G1 -25397P on permits issued for wells No.11 & 17, Until Regional Water Plans are established as set forth by the Chelan Agreement, Ecology is developing the Interim Solutions to Public Water Supply Needs policy. These solutions involve; considering alternatives in lieu of developing new water sources. As this application involves a change in the point of withdrawal (replacement well) and a change in place of use (intertie) and no new water source, it is consistent with this Interim Solutions policy. The Instream Resource Protection Program (IRPP) for the Cedar,Sammamish Basin was adopted in September, 1979_ Under Chapter 173-508 WAC, Lake Washington (including ground water in continuity with the lake) is closed to further consumptive use. A.s this use from Well No. 5 was certificated prior to enactment of this code, and as the drilling of this replacement well (10' distant from original well) will not increase the potential for hydraulic continuity, this change is acceptable under the regulation. This application is consistent with the State Surface and Ground Water Code. Chapters 90-03 and 90.44 RCW. as described below_ This change meets requirements of RCW 90.03.383 (Interties), in that by letter (Bucknell, June 22, 1992), Ecology accepted Renton's internes that had been in place prior to January 1, .1991 as vested. Changing the place of use an this existing certificate completes the required process. This change also meets requirements defined in RCW 90.44.100 for approving an amendment to a certificate for a change in the point(s) of withdrawal in that: 1. The new well taps the same body of public ground water as the original well. 2. The original well has been properly abandon. 3. The changes do not enlarge the right conveyed by the original certificate_ 4. Existing rights will not be impaired_ CONCLUSION In accordance with chapters 90.03 and 90.44 RCW, I find that the certificate holder has perfected this right by putting the water to full beneficial use. This change will not enlarge the right conveyed on the original certificate, nor will the granting of this change impair existing rights or be detrimental to the public welfare. Therefore, a superseding certificate should be issued subject to existing rights and indicated provisions. Report Continued —COMMENDATIONS perseding certificate should be issued as original for a withdrawal of 200 GPM and 320 AF!YR; with the same priority date of April 14, 1966; with the change being in the point of withdrawal (new well) and the place of use (current service area including interties); and the right is subject to the following recommendations and provisions: An approved measuring device shall be installed and maintained in accordance with RCW 90.03,360, WAC 504- 64-020 through 508-64-040 !Installation of eraticn and .mintenanc readings shall be recorded monthly and this data shall be maintained and be made available to the Department of Ecology upon request. In order to monitor the resource, static water level (SWL) shall be measured at least once each month. Measurements shall be taken after the pump has been shut off and the water level in the well has been stabilized. The data shall be maintained and made available to Ecology upon request. However, Ecology's Water Resources Section (NWRO) shall be notified if the SWL is determined to be below the level normally recorded at that time of year. See enclosed form. This permit is subject to the implementation of the minimum requirements established in the Interim Guidelines for Public Water Systems Regarding Water Use Reporting.

(1 acre-foot 325,850 gallons.) Use of the waters to be appropriated under this application will be for a public water supply. State Board of Health rules require every owner of a public water supply to obtain written approval from the State Director of Health prior to any new construction or alterations of a public water supply. The applicant is advised to contact the Washington State Department of Health, 304 Public Health Building, Olympia, with regard to the need for compliance. The installation of an access port as described in attached Ground Water Bulletin No. 1 shall be required prior to issuance of final certificate of water right. The applicant may, for his own convenience, wish to install an air -line and gage in addition to the access port. Studies of water usage in the Renton area reveal a demand of 120 gallons per capita per day. For the projected population of 84,000 as of 1971, the annual requirement would be 11,289.5 acre-feet. The quantity of 4839 acre-feet granted under this application represents the maximum that could be withdrawn at a continuous pumping at 3000 gallons per minute.

PRPIECT BY THIS LATE: C*MPLETE PMU17M BV TWS GATE: WATEA PUT TO FULL USE Br THIS SANE 1 year from permit issuance 3 years from permit issuance 6 years from permit issuance REPORT BACKGROUND The application was received on 1-2-86. It requests 1600 gpm (gallons per minute) from a well for Municipal Supply. Notice was published in the Valley -Daily News on February 7 and 14, 1986. No protests were filed within the 30 day protest period. The well covered by this application is known as well #10. Renton has submitted eight applications which are pending. This report will cover the issues involving five of the applications dealing with wells 10, 11, 12, and 17 as they reflect similar conditions. On March 9, 1988 Renton requested a Temporary Permit to drill and test wells located within the Maplewood Golf Course. The Temporary Permit was issued on March 14, 1988. During the time Renton's applications were pending evaluation, several letters of concern were received. The following is a brief summary of the concerns: 1. Seattle Water Department raised questions during the environmental review process of Renton's Water System Plan. They want to know what studies were made to show that the Maplewood Golf Course wells were not hydraulically linked to the Cedar River and how might the wells and delivery facilities impact Seattle's pipeline in the vicinity. 2. Sate Paffile, area developer, wants Renton to document that additional water is really needed and that the wells will not draw from an aquifer interrelated with the Cedar liver. Mr_ Paffile also wants Renton to take a serious look at conservation measures to curb additional water right acquisitions. 3. The Muckleshoot Indian Tribe requests a thorough analysis of the interaction between the aquifer in which the wells are developed and flows of the Cedar River. They also want to see better conservation measures. These issues will be addressed in detail later in the report. Renton has complied with SEPA requirements with regard to the development of wells 70,11,12, and 17. INVESTIGATION A field visit was conducted on December 20, 1991 by Jerry Liszak, Regional Hydrogeologist, and Janet Jorg of the Northwest Regional Office. Ron Olsen, Utilities Engineer for Renton, and Geof Clayton, Hydrogeologist for Renton's consulting firm of RH2 Engineering, were present during the visit to Renton's well sites located in the Maplewood Golf Course. The site for well 10 is two miles east of Renton on the north side of Highway 169 (Maple Valley Rd.) in the Maplewood Golf Course. The application identifies the well as being within the NW 1./4 of section 23, township 23N, range 5E and the public notice reflects this location. During; evaluation it was found that well 10 is pr d to be in the NW1/4 of section 22. The maps and supporting data for all of Renton's applications in th .lewood Golf Course show well 10 in section 22. As the intent of notifying; area residents of Renton's plans to develop wells within the Maplewood Golf Course was sufficiently documented by all their applications, requiring republication for correct location of well 10 would not serve the purpose of publication any more than what has already been done. Report Continued Renton's water system provides water to an area of 16 square miles. The current system consists of 6 wells located in the downtown area and one artesian spring. There are 5 metered interties with Seattle for emergency supply plus emergency intertie with Kent. Renton has one wholesale customer-Lakeridge Bryn Mawr Water District. Six reservoirs currently provide storage for Renton with another under construction. Applications for wells 10, 11, 12, and 17 are submitted to provide better control of the water supply and more flexibility in operating the system to meet peak demands. Renton holds water rights totaling 14,809 acre-feet per year. The chart below itemizes the existing rights. CERT. NO.

His report of findings indicate there are three aquifers identified within the Maplewood Golf Course. A shallow or unconfined upper water table aquifer can be encountered to depths of 50 feet. Two deeper confined aquifers (known as the intermediate and the deep aquifers) occur at different locations within the golf course but they are not superimposed over each other. The unconfined water table Report Continued intermediate aquifers are separated by a leaky aquitard making the intermediate aquifer semi -confined. [cep aquifer is encountered at the eastern end of the golf course and is a highly pressurized artesian er. Exploratory drilling and testing did not encounter the deep aquifer under the intermediate aquifer in vicinity of well 11 or 17 or the observation well (OBW-1) nor was the intermediate aquifer encountered in (lie vicinity of the deep aquifer. Wells 10 and 12 are to be developed in the intermediate aquifer also. Recorded hydrostatic pressures of wells tapping the intermediate aquifer indicate no hydraulic connection with the deep aquifer. Wells 11 and 17 were drilled and developed in the intermediate aquifer. Well 11 was drilled to a depth of 345 feet and well 17 was drilled to a depth of 346 feet. Based on the information obtained from the observation well (OBW-1) and wells 11 and 17 indicating water is available, Renton plans to drill well 10 and 12 near OBW-1 to be developed in the intermediate aquifer for a maximum quantity of 1600 gpm from each well. Approval of this application would carry conditions for proper well construction and adequate testing. Until Regional Water Plans are established as set forth by the Chelan Agreement, Ecology implemented interim policies to address short term water needs of larger public water systems in growth areas. Therefore applications for wells 10, 11, 12, and 17 are considered with respect to Renton's needs up to year 2000. The long term water needs for Renton will be evaluated as part of a regional water resources planning process and will be affected by implementation of the Growth Management Act. To evaluate an application for water right, the applicant must provide documentation as to need and availability of water on an instantaneous basis and demonstrate the amount of water needed on an annual basis to satisfy all uses. Renton's Comprehensive Water System Plan (released in March 1992) addresses their need to satisfy Department of Health(DOH) peak demand requirements. Renton shows they are 8,577 gpm short of DOH requirements, thus the instantaneous quantities associated with wells 10, 11, 12, and 17 are requested to reduce deficiencies. The Water System Plan doesn't address needs based on actual consumption per capita or yearly consumption rates_ By request, Renton provided water consumption figures for 1989 and 1991 which show they used less than 8,000 af/yr (acre feet per year). The population for 1991 as reported to DOH was 35,360 and t' umber of connections was 11,735. mg current consumption (8000 of/yr) plus adding annual growth rate of 1.8% (from King County Annual Growth Report for Renton area) up to the year 2000 places the annual quantity at 9088 acre-feet which is below the yearly amount already granted by existing rights (14,809 acre-feet)_ Therefore the applications concerning wells 10, 11, 12, and 17 will not be considered for any additional annual quantity. Ecology's interim policies do allow public water systems to increase the ability and flexibility of the systems to meet demands within existing yearly amounts for that interim period until regional water resources plans are accepted. Ecology will monitor Renton's consumption and growth over the next six to eight years for possible adjustments through future permitting actions. As well 11 is recommended for a reduced quantity of 2500 gpm, the quantities considered for the applications pertaining to well 11 are 1600 gpm for GI -24781 and 900 gpm for G 1-25396_ Application G 1.25397 for well 17 will be considered for a reduced quantity of 1500 gpm. Application G 1-24783 for well 10 is considered for a maximum quantity of 1600 gpm and application G1-24782 for well 12 is considered for a maximum of 1600 gpm. The yearly volume that could be allocated from each application would be calculated at 70% of continuous pumping, with the stipulation that total withdrawal from all Renton's sources could not exceed the city's existing water right certificates (14,809 aflyr). Ecology's interim policies also require public water systems to make the maximum use of conservation. Renton's current conservation plan identifies a 6.5% reduction in water use with implementation of the various components. Many measures are already in effect with the remainder scheduled for implementation within the coming year. The conservation plan and implementation is consistent with Ecology's Interim Guidelines for Public Water Systems. Ecology needs to monitor the effects of conservation measures on water consumption over the next few years. Review of office records indicates three downstream rights on the Cedar River which total 3.02 cfs (cubic feet per second). One right was issued to Northwest Water Co. in the amount of 1.0 cfs for the community of ' ydale, which is now served by Renton. Ft.,__ and office investigation show no wetlands in the area that would be adversely affected by the proposed withdrawals from well 10. Report Continued CONSIDERATION OF OBJECTIONS All three proponents submitting concerns on Renton's new applications request analysis of interaction between the Maplewood Golf Course wells and flows in the Cedar River. The hydrogeologist's review indicates that wells 10, 11, 1.2, and 17 should be considered in hydraulic continuity with the Cedar River. The wells are developed in the semi -confined intermediate aquifer and pumping from the wells will induce leakage from the unconfined shallow aquifer. As rate of leakage has not been quantified and the interrelationship is complex, our hydrogeologist recommends long term monitoring of the shallow and intermediate aquifers. Renton must show that pumping the wells will not decrease Cedar River flows to be in compliance with the intent of the Cedar-Sammamish Instream Resource Protection Program (WAC 173-508). Renton would be required to prepare an interim management plan detailing procedures for monitoring pumping and assuring that flows in the river are not decreased by use of wells 10, 11, 12, and 17. The plan would need to be approved by Water Resources prior to beneficial use of water from the wells. An ongoing management plan would be required before a certificate of water right could issue. To aid monitoring of Cedar River flows, the USGS gage 12114000 located in downtown Renton would be permanently maintained plus Renton would be required to establish and permanently maintain at least two additional upstream gaging stations- one in the Narrows area downstream of the golf course and another gaging station upstream of the influence of the Maplewood Golf Course aquifers. A second issue raised is whether Renton really needs additional water rights. As earlier stated in the report Renton is not currently meeting DOH peak flow requirements; therefore Renton does need additional water rights for peak instantaneous quantities. Approval of the applications for wells 10, 11, 12, and 17 would help Renton toward meeting DOH requirements_ Renton would also have the flexibility to better manage their entire system for peak daily demands while providing alternate sources of water should contamination occur in the downtown well field. Our analysis indicates that Renton has been granted sufficient water rights in terms of annual quantities to meet consumption demands beyond the year 2000. Consequently the applications covering wells 10, 11, 12, and 17 are only being considered for additional instantaneous quantities and not additional annual quantities. A third concern involves Renton's Comprehensive Water System flan and Conservation Plan. It is felt that Renton is not conserving water to offset the need for additional water. Renton has provided information showing that conservation measures have and are being implemented which will reduce but not completely eliminate the need for additional water. The water system plan illustrates the effect of full conservation implementation on reduction of water consumption. In evaluating the applications for wells 10, 11, 12, and 17, instantaneous quantities and total consumption figures used to forecast Renton's needs until the year 2000 were based on average daily demands including aggressive conservation measures. Approval of Renton's applications would carry conditions to monitor actual consumption quantities, population, and service connections to be analyzed prior to certificate of water right issuance for effective conservation implementation and growth projections. In order to approve an application for permit, the following tests must be met: water is available for appropriation, water must be for a beneficial use, water use is not detrimental to public interest, and the use will not adversely affect existing rights. Taking into account the concerns expressed by the City of Seattle, Mr. Paffile, and the Muckleshoot Indian Tribe all four tests are answered in the affirmative. The quantities as recommended in this report are adequately conditioned to assure protection of existing rights including instream flows and to assure that the proposed use will not be detrimental to the public interest. The tests conducted on observation wells, and wells 1I and 17, show water is available for appropriation and that the use for municipal supply is a beneficial use. CONCLUSION In accordance with Section 90.03 (and 90.44 RCW), I find that there is water available for this beneficial appropriation from the source in question and the appropriation as recommended will not impair existing rights or be detrimental to the public welfare. Therefore, permit should issue subject to existing rights and indicated provisions. RECOMMENDATIONS A permit should issue for well 10 for a maximum quantity of 1600 gpm 1792 af/yr (based on 70% continuous pumping) and not cumulative to existing rights for municipal supply_ Report Continued I annual withdrawal from this allocation (GI -24783) and all rights held by Renton shall not exceed 14,809 eet. The amount of water granted is a maximum limit that shall not be exceeded and the water user shall be entitled only to that amount of water within the specified limit that is beneficially used and required for the actual crop grown on the number of acres and place of use specified. A well log of the completed well shall be submitted by the driller to the Department of Ecology y within thirty (30) days of completion of this well. This well log shall be complete and all information concerning the static water level in the completed well, in addition to any pump test data, shall be submitted as it is obtained. Installation and maintenance of an access port as described in Ground Water Bulletin No. 1 is required. An air line and gauge may be installed in addition to the access port. All water wells constructed within the state shall meet the minimum standards for construction and maintenance as provided under RCW 18.104 (Washington Water Well Construction Act of 1971) and Chapter 173-160 WAC (Minimum Standards for Construction and Maintenance of Water Wells). Static water level (SWL) shall be measured at least once each month. Measurements shall be taken after the pump has been shut off and the water level in the well has been stabilized. The data shall be maintained and made available to Ecology upon request. However, Ecology's Water Resources Section (NWRO) shall be notified if the SWL is determined to be below the level normally recorded at that time of year. See enclosed form. An approved measuring device shall be installed and maintained in accordance with RCW 90.03.360, WAC 508- 64-020 through WAC 508-64-040 (Installation, operation and maintenance requirements attached hereto). r readings shall be recorded monthly and this data shall be maintained and be made available to the rtment of .....,.ogy upon request. See enclosed form. The aquifer test shall be conducted under the supervision of a professional ground water consultant. The well shall be tested at a constant rate no less than the maximum design rate at which the well source will be used. WRIS Information Bulletin 30 (copy enclosed) shall be used as a guideline for designing and conducting; the aquifer test. For water table aquifers, pumped water produced during the test shall be routed away from all wells and discharged such that this water will not recharge the drawdown cone during the test. Pumping during the test shall be conducted for a minimum of 24 hours, with stabilization of the pumping well water level occurring for at least the last 4 of those hours. Stabilization is defined as a drop in water level of less than or equal to 0.1 feet drawdown per hour during pumping. For water table (unconfined) aquifer conditions, the test shall be conducted for 72 hours or until a minimum of 4 hours of drawdown has been detected in an observation well, whichever is shorter. At the completion of pumping, recovery data shall be collected from all wells until the pumped well achieves either 95% recovery, or its water level is within 0.5 feet of static water level, whichever takes longer. The test must be designed and conducted to determine the following: a. The distance and time drawdown response within the producing aquifer to the proposed ground water withdrawal. To accomplish this, an observation well completed in the same aquifer and within a reasonable distance, shall be shut off and monitored for drawdown and recovery during the aquifer test. b. Aquifer transmissivity. C. Aquifer storage coefficient or specific yield. d. The effect of the proposed ground water withdrawal on existing ground water and surface water users. This shall include the potential effect of the withdrawal on local wetlands, springs, streams and lakes. Specifically it must be shown that the proposed ground water withdrawal will have no effect upon Cedar River flows. Report Continued The following outlines sampling and analysis requirements specified by the Washington State Department of Health. This section has been included to decrease the likelihood that applicants will need to perform a second test in order to comply with requirements of that agency. Water samples must be collected from the well using proper sampling procedures and analyzed by a laboratory certified by the Department of Health.

REPORT OF EXAMINATION DESCRIPTION OF PROPOSED WORKS Well 345 feet deep, 16 inch diameter Static water level 11 feet below top of well ction to reservoirs BEGIN PR6SECT by TTtt$ NATE: (X)MPLETr. PfAIECr BY THIS DAIS""' TER FVT TO GULL VSE BY rHIS DATE Started 3 years from permit issuance 6 years from permit issuance REPORT BACKGROUND The application was received 1-2-86. It requests 1600 gpm (gallons per minute) from a well for Municipal Supply. Notice was published in the Valley Daily ews on February 7 and 14, 1986, No protests were filed within the 30 day protest period. On March 9, 1988 the applicant requested a Temporary Permit to drill and test the well. The Temporary Permit was issued on March 14, 1988. The well covered by this application is known as well #11. In 1989 Renton submitted a second application for well #11 (G1-25396) for an additional 1404 gpm. Also in 1989 Renton submitted application G1-25397 for 3004 gpm from a well (well #17) which is within 50 feet from well #11. As wells 11 and 17 are in close proximity and share similar issues, this report will address and evaluate all three applications (G1-24781, G1-25396, and G1-25397) which pertain to the wells. During the time Renton's applications were pending evaluation, several letters of concern were received. The •ing is a brief summary of the concerns: Seattle Water Department raised questions during the environmental review process of Renton's Water System Plan. They want to know what studies were made to show that wells 11 and 17 were not hydraulically linked to the Cedar River and how might the wells and delivery facilities impact Seattle's pipeline in the vicinity. 2. Sam Paffft, area developer, wants Renton to document that they really need additional water and that the wells will not draw from an aquifer interrelated with the Cedar River. He also wants Renton to take a serious look at conservation measures to curb additional water right acquisitions. 3. The Muckleshoot Indian Tribe requests a thorough analysis of the interaction between aquifers the wells are developed into and flows of the Cedar River plus better conservation treasures. Renton has complied with SE.PA requirements with regard to the development of wells 11 and 17, A Mitigated Declaration of Non Significance was issued by Renton on May 4, 1988_ INVESTIGATION A field visit was conducted on December 20, 1991 by Jerry Liszak, Regional Hydrogeoiogist, and Janet Jorg of the Northwest Regional Office. Ron Olsen, Utilities Engineer for Renton, and Geof Clayton, Hydrogeologist for Renton's consulting engineering firm of RH2 Engineering, were present during the visit to Renton's well sites. The site for wells 11 and 17 is 2 miles east of Renton on the north side of Highway 169 (Maple Valley Rd.) in the Maplewood Golf Course. The applications correctly identify the well locations as being within the NE1I4 NE114 Section 21, Township 23N, Range 5E of King County. 's water system provides water to an area of 16 square miles. The current system consists of 6 wells 1 in the downtown area and one artesian spring. There are 5 metered interties with Seattle for emergency supply plus emergency intertie with Kent. Renton has one wholesale customer-Lakeridge Bryn Mawr Water District_ Six reservoirs currently provide storage with another under construction. Report Continued Applications for wells 11 and 17 are submitted to provide better control of the water supply and more flexibility in operating the system to meet peak demands. Renton holds water rights totaling 14,809 acre-feet per year. The chart below itemizes the existing rights. CERT. NO.

Well 11 was drilled in August 1988 to a depth of 345 feet by 16 inches in diameter. Well 17 was constructed at the same time to a similar denth (346 feet) but with a larger casing diameter (20 inches). The two wells are 50 feet apart. Regional Hydrogeologist, Jerry Liszak, reviewed data submitted by the applicant's consultants and other pertinent data relating to hydrogeology of the area. His review and report of findings indicate that both wells I I and 17 are developed in the same aquifer (referred to as the intermediate aquifer) and are considered a well field (similar depth, close proximity, and same aquifer). Quoted in part, the hydrogeologist review states: Wells No. 11 and 17 were each tested using short term step rate and 24 hour constant rate pumping. The test results indicate that the transmissivity of the aquifer is between 45,000 and 60,000 gallons per day per foot of drawdown. The storage coefficient is approximately .005 which indicates the aquifer is confined. A recharge boundary was encountered after approximately 110 minutes of pumping in the 24 hour tests for both wells 11 and 17. Based on this and an understanding of the local geology, the recharge is assumed to Report Continued be from leaky conditions in the hydrogeologic strata, or the lower permeability zone known as the aquitard, tween the shallow and intermediate aquifers. Based on the test results, the recommended pumping rate for Well No. 11 is 2,500 gpm and the recommended pumping rate for Well No. 17 is 1,500 gpm. It is calculated that well interference belwee.n the two wells will add between 30 and 50 feet of drawdown in each well depending on pumping rates and duration. Renton has not used either well to date as they are waiting for a decision on the water right applications. If apprccvt'd, th:. City will proceed ::ith fuiding for L. n;;tl acCl lii of a pw—npiclg dtdLiuil aild dlaiiibUtlUn 11r1Cs tO the wells. Until Regional Water Plans are established as set forth by the Chelan Agreement, Ecology has implemented interim policies to address short term water needs of larger public water systems in growth areas. Therefore, the applications for wells 11 and 17 are considered with respect to Renton's needs up to year 2000. The long term water needs for Renton will be evaluated as part of a regional water resources planning process and will be affected by implementation of the Growth Management Act. To evaluate an application for water right, the applicant must provide documentation as to need and availability of water on an instantaneous basis and demonstrate the amount of water needed on an annual basis to satisfy all uses. Renton's Comprehensive Water System flan (released in March 1992) addresses their need to satisfy Department of Health(DOH) peak demand requirements. Renton shows they are 8,577 gpm short of DOH requirements, thus the instantaneous quantities associated with wells 11 and 17 are to reduce. deficiencies. The Water System Plan doesn't address needs based on actual consumption per capita or yearly consumption rates. By request, Renton provided yearly production figures for 1989 and 1991 which show they used less than 8,000 a[/yr (acre-feet per year). The population for 1991 as reported to DOH was 35,360 and the number of connections was 11,735. Fi --ing current consumption (8000 of/yr) plus adding annual growth rate of 1.8%n (from King County Annual Report for Renton area) up to the year 2000 places the annual quantity at 9088 acre-feet which is below t arly amount already granted by existing rights (14,809 acre-feet). Therefore the applications concerning wells 11 and 17 will not be considered for any additional annual quantity. Ecology's interim policies do allow public water systems to increase the ability and flexibility of the system to meet demands within existing yearly amounts for that interim period until regional water resources plans are accepted. Ecology will monitor Renton's consumption and growth over the next six to eight years for possible adjustments on future actions. As well I I is recommended for a reduced quantity of 2500 gpm, the quantities considered for the applications pertaining to well 11 are 1600 gpm for G1-24781 and 900 gpm for G1-25396. Application G1-25397 for well 17 will be considered for a reduced quantity of 1500 gpm. The yearly volume that could be pumped from each application would be calculated at 70% of continuous pumping, but the total consumptive allocation would not exceed the city's existing rights. Ecology's interim policies also require public water systems to make the maximum use of conservation, Renton's current water conservation plan identifies a 6.511b reduction with implementation of the various components. Many measures are already in effect with the remainder scheduled to he implemented within the coming year. The conservation plan and implementation is consistent with Ecology's Interim Guidelines for Public Water Systems. Ecology needs to monitor the effects of conservation measures oil water consumption over the next few years_ Review of office records indicates three downstream rights on the Cedar River which total 3.02 cfs (cubic feet per second). One right was issued to Northwest Water Co. in the amount of 1.0 cfs for the community of Kenneydale, which is now served by Renton. Field and office investigation show no wetlands in the area that would be adversely affected by the proposed withdrawals from wells 11 and 17. C—IDERATION OF OBJECTIONS f ee proponents submitting concerns on Renton's new applications request analysis 01 interaction between wells 1I and 17 and flows in the Cedar River. The hydrogeologist's review indicates that wells 11 and 17 should be considered in hydraulic continuity with the Cedar River. The wells are developed in the semi -confined intermediate aquifer and pumping from the wells Report Continued will induce leakage from the unconfined shallow aquifer. As the rate of leakage has not been quantified, our hydrogeologist recommends long term monitoring of the shallow and intermediate aquifers. Renton must show that pumping the wells will not decrease Cedar River flows to be in compliance with the intent of the Cedar- Sammamish Instream Resource Program (WAC 173-508)_ Renton would be required to prepare an interim management plan detailing procedures for monitoring pumping and assuring that flows in the river are not decreased by the use of wells 11 and 17. The plan would need to be approved by Water Resources prior to beneficial use of water from the wells. An ongoing management plan would be required before a certificate of water right could issue. To aid monitoring of Cedar River flows, the USGS gage 12119000 located in downtown Renton would be permanently maintained plus Renton would be required to establish and permanently maintain at least two additional upstream gaging stations - one in the Narrows area downstream of the golf course and another gaging station upstream of the influence of the. Maplewood Golf Course aquifers. A second issue raised is whether Renton really needs additional water rights. As earlier stated in the report Renton is not currently meeting DOH peak flow requirements; therefore Renton does need additional water rights for peak instantaneous quantities. Approval of the applications for wells 11 and 17 would help Renton toward meeting DOH requirements. Renton would also have the flexibility to better manage their entire system for peak daily demands while providing alternate sources of water should contamination occur in the downtown well field. Analysis indicates that Renton has been granted sufficient water rights in terms of annual quantities to meet consumption demands beyond the year 2000. Consequently the applications covering wells 11 and 17 are only being considered for additional instantaneous quantities and not additional annual quantities. A third concern involves Renton's Comprehensive Water System Plan and Conservation Plan. It is felt that Renton is not conserving water to offset the need for additional water. Renton has provided information showing that conservation measures have and are being implemented which will reduce but not completely eliminate the need for additional water. The comprehensive water system pian illustrates the effect of full conservation implementation on reduction of water consumption. In evaluating the applications for wells 11 and 17, instantaneous quantities and total consumption figures used to forecast Renton's needs until the year 2000 were based on average daily demands including aggressive conservation measures. Approval of applications concerning wells 11 and 17 would carry conditions to monitor actual consumption quantities, population, and service connections to be analyzed prior to certificate of water right issuance for effective conservation implementation and growth projections. In order to approve an application for permit, the following tests must be met: water is available for appropriation, water must be for a beneficial use, water use is not detrimental to public interest, and the use will not adversely effect existing rights. Taking into account the concerns expressed by the City of Seattle, Mr. I'affiie, and the Muckleshoot Indian Tribe all four tests can be answered in the affirmative. The quantities as recommended in this report are adequately conditioned to assure protection of existing rights including Instream flows and to assure that the proposed use will not be detrimental to the public interest. The pump tests show water is available for appropriation and that the use for municipal supply is a beneficial use. CONCLUSION In accordance with Section 90.03 (and 90.44 RCW), I find that there is water available for this beneficial appropriation from the source in question and that the appropriation as recommended will not impair existing rights or be detrimental to the public welfare. Therefore, permit should issue subject to existing rights and indicated provisions.

Notice was published in the Valley Daily News on March 29 and April 5, 1989. No protests were filed within the 30 day protest period. On March 9, 1988 Renton requested a Temporary Permit to drill and test wells located within the Maplewood Golf Course. The Temporary Permit was issued on March 14, 1988. During the time Renton's applications were pending evaluation, several letters of concern were received. The following is a brief summary of the concerns: 1. Seattle Water Department raised questions during the environmental review process of Renton's Water System Plan. They want to know what studies were made to show that wells 1.1 and 17 were not hydraulically linked to the Cedar River and how might the wells and delivery facilities impact Seattle's pipeline in the vicinity. Sam Paffile, area developer, wants Renton to document that additional water is really needed and that the wells will not draw from an aquifer interrelated with the Cedar River. Mr. Paffile also wants Renton to take a serious look at conservation measures to curb additional water acquisitions_ 3. The Muckleshoot Indian Tribe requests a thorough analysis of the interaction between the aquifer in which the wells are developed and flows of the Cedar River. They also want to see better conservation measures. These issues will be addressed in detail later in the report. Renton has complied with SHPA requirements with regard to the development of wells 11 and 17. A Mitigated Declaration of Non Significance was issued by Renton on May 4, 1988. The well covered by this application is known as well # 11. Renton has another pending application on well 11 (GI -24781) filed in 1986 for 1600 gpm. Also pending review is application GI -25397 requesting 3000 gpm from well #17 which is within 50 feet from well 11. As wells I I and 17 are in close proximity and share similar issues, this report will address and evaluate all three applications (G1-24781, G1-25396, and G1-25397) which pertain to the wells. INVESTIGATION Afield visit was conducted on December 20, 1991 by Jerry Liszak, Regional Hydrogeologist, and Janet Jorg of the Northwest Regional Office. Ron Olsen, Utilities Engineer for Renton, and Geof Clayton, Hydrogeologist for Renton's consulting firm of RH2 Engineering, were present during the visit to Renton's well sites located in the Maplewood Golf Course. to for wells 11 and 17 is two miles east of Renton on the north side of Highway 169 (Maple Valley Rd.) Maplewood Golf Course. The applications correctly identify the well locations as being within the NF -1/4 NEI/4 Section 21, Township 23N, Range 5E of King County. Renton's water system provides water to an area of 16 square miles. The current system consists of 6 wells located in the downtown area and one artesian spring. There are 5 metered interties with Seattle for emergency Report Continued supply plus emergency intertie with Kent. Renton has one wholesale customer-Lakeridge Bryn Mawr Water District. Six reservoirs currently provide storage for Renton with another under construction. Applications for wells 11 and 17 are submitted to provide better control of the water supply and more flexibility in operating the system to meet peals demands. Renton holds water rights totaling 14,809 acre-feet per year. The chart below itemizes the existing rights. CERT. NO.

Well 11 was drilled in August 1988 to a depth of 345 feet by 16 inches in diameter. Well 17 was constructed at the same time to a similar depth (346 feet) but with a larger casing diameter (20 inches). The two wells are 50 feet apart. Regional Hydrogeologist, Jerry Liszak, reviewed data submitted by the applicant's consultants and other pertinent data relating to hydrogeology of the area. His review and report of findings indicate that both wells Report Continued 17 are developed in the same aquifer (referred to as the intermediate aquifer) and are considered a well imilar depth, close proximity, and same aquifer). Quoted in part, the hydrogeologist review states: Wells No. 11 and 17 were each tested using short term step rate and 24 hour constant rate pumping. The test results indicate that the transmissivity of the aquifer is between 45,000 and 60,000 gallons per day per foot of drawdown. The storage coefficient is approximately .005 which indicated the aquifer is confined. A recharge boundary was encountered after approximately 110 minutes of pumping in the 24 hour tests for both wells 11 and 17. Based on this and an understanding of the local geology, the recharge is assumed to be from leaky conditions in the hydrogeologic strata, or the lower permeability zone known as the aquitard, between the shallow and intermediate aquifers. Based on the test results, the recommended pumping rate for Well No. 11 is 2,500 gpm and the recommended pumping rate for Well No. 17 is 1,500 gpm. It is calculated that well interference benvicen the two wells will add between 30 and 50 feet of drawdown in each well depending on pumping rates and duration. Renton has not used either well to date as they are waiting for a decision on the water right applications. If approved, the City will proceed with funding for construction of a pumping station and distribution lines to the wells. Until Regional Water Plans are established as set forth by the Chelan Agreement, Ecology implemented interim policies to address short term water needs of larger public water systems in growth areas. Therefore applications for wells 11 and 17 are considered with respect to Renton's needs up to year 2000_ The long terns water needs for Renton will be evaluated as part of a regional water resources planning process and will be affected by implementation of the Growth Management Act. To evaluate an application for water right, the applicant must provide documentation as to need and availability of water on an instantaneous basis and demonstrate the amount of water needed on an annual basis to satisfy al s. Renton's Comprehensive Water System Plan (released in March 1992) addresses their need to satisfy I went of Health(DOH) peak demand requirements. Renton shows they are 8,577 gpm short of DOH re,__rements, thus the instantaneous quantities associated with wells 11 and 17 are requested to reduce deficiencies. The Water System Plan doesn't address needs based on actual consumption per capita or yearly consumption rates. By request, Renton provided water consumption figures for 1989 and 1991 which show they used less than 8,000 af/yr (acre feet per year). The population for 1991 as reported to D011 was 35,360 and the number of connections was 11,735. Figuring current consumption (8000 af/yr) plus adding annual growth rate of 1.8%'0 (from King County Annual Growth Report for Renton area) up to tate year 2000 places the annual quantity at 9088 acre-feet which is below the yearly amount already granted by existing rights (14,809 acre-feet). Therefore the applications concerning wells 11 and 17 will not be considered for any additional annual quantity. Ecology's interim policies do allow public water systems to increase the ability and flexibility of the systems to meet demands within existing yearly amounts for that interim period until regional water resources plans are accepted. Ecology will monitor Renton's consumption and growth over the next six to eight years for possible adjustments through future permitting actions. As well 11 is recommended for a reduced quantity of 2500 gpm, the quantities considered for the applications pertaining to well: 11 are 1600 gpm for G1-24781 and 900 gpm for G1-25396. Application GI -25397 for well 17 will be considered for a reduced quantity of 1500 gpm. The yearly volume that could be pumped from each application would be calculated at 70% of continuous pumping, with the stipulation that total withdrawal from all Renton's sources could not exceed the city's existing water right certificates (14,809 of/yr). Ecology's interim policies also require public water systems to make the maximum use of conservation. Renton's current conservation plan identifies a 6.5% reduction in water use with implementation of the various components. Many measures are already in effect with the remainder scheduled for implementation within the coming year. The conservation plan and implementation is consistent with Ecology's Interim Guidelines for Public Water Systems. Ecology needs to monitor the effects of conservation measures on water consumption ov next few years. Review of office records indicates three downstream rights on the Cedar River which total 3.02 cfs (cubic feet per second). One right was issued to Northwest Water Co. in the amount of 1.0 cfs for the community of Kenneydale, which is now served by Renton. Report Continued Field and office investigation show no wetlands in the area that would be adversely affected by the proposed withdrawals from wells 11 and 17. CONSIDERATION OF OBJECTIONS All three proponents submitting concerns on Renton's new applications request analysis of interaction between wells 11 and 17 and flows in the Cedar River. The hydrogeologist's review indicates that wells 11 and 17 should be considered in hydraulic continuity with the Cedar River. The wells are developed in the semi -confined intermediate aquifer and pumping from the wells will induce leakage form the unconfined shallow aquifer. As rate of leakage has not been quantified, our hydrogeologist recommends long term monitoring of the shallow and intermediate aquifers. Renton must show that pumping the wells will not decrease Cedar River flows to be in compliance with the intent of the Cedar- Sammamish Instream Resource Protection Program (WAC 173-508). Renton would be required to prepare an interim management plan detailing procedures for monitoring pumping and assuring that flows in the river are not decreased by the use of wells 11 and 17. The plan would need to be approved by Water Resources prior to beneficial use of water from the wells. An ongoing management plan would be required before a certificate of water right could issue. To aid monitoring of Cedar River flows, the USGS gage 12114000 located in downtown Renton would be permanently maintained plus Renton would be required to establish and permanently maintain at least two additional upstream gaging stations- one in the Narrows area downstream of the golf course and another gaging station upstream of the influence of the Maplewood Golf Course aquifers. A second issue raised is whether Renton really needs additional water rights. As earlier stated in the report Renton is not currently meeting DOH peak flow requirements; therefore Renton does need additional water rights for peak instantaneous quantities. Approval of the applications for wells 11 and 17 would help Renton toward meeting DOH requirements. Renton would also have the flexibility to better manage their entire system for peals daily demands while providing alternate sources of water should contamination occur in the downtown well field. Our analysis indicates that Renton has been granted sufficient water rights in terms of annual quantities to meet consumption demands beyond the year 2000. Consequently the applications covering wells 11 and 17 are only being considered for additional instantaneous quantities and not additional annual quantities. A third concern involves Renton's Comprehensive Water System Plan and Conservation Plan. It is felt that Renton is not conserving water to offset the need for additional water. Renton has provided information showing that conservation measures have and are being implemented which will reduce but not completely eliminate the need for additional water_ The water system plan illustrates the effect of full conservation implementation on reduction of water consumption. In evaluating the applications for wells 11 and 17, instantaneous quantities and total consumption figures used to forecast Renton's needs until the year 2000 were based on average daily demands including aggressive conservation measures_ Approval of Renton's applications would carry conditions to monitor actual consumption quantities, population, and service connections to be analyzed prior to certificate of water right issuance for effective conservation implementation and growth projections. In order to approve an application for permit, the following tests must be met: water is available for appropriation, water must be for a beneficial use, water use is not detrimental to public interest, and the use will not adversely affect existing rights. Taking into account the concerns expressed by the City of Seattle, Mr. Paffile, and the Muckleshoot Indian Tribe all four tests are answered in the affirmative_ The quantities as recommended in this report are adequately conditioned to assure protection of existing rights including instream flows and to assure that the proposed use will not be detrimental to the public interest. The pump tests show water is available for appropriation and that the use for municipal supply is a beneficial use. CONCLUSION In accordance with Section 90.03 (and 90.44 RCW), I find that there is water available for this beneficial appropriation from the source in question and the appropriation as recommended will not impair existing rights or be detrimental to the public welfare. Therefore, permit should issue subject to existing rights and indicated provisions. RECOMMENDATIONS A permit should issue for a reduced quantity of 900 gprn (1008 acre feet per year based on 70% continuous pumping and not cumulative to existing held rights) from a well (#11) for municipal supply. Report Continued 1 annual withdrawal from this allocation (GI -25396) and all rights held by Renton shall not exceed 14,809 feet. An approved measuring device shall be installed and maintained in accordance ,01i RCW 90.03.360, WAC 508- 64-020 through WAC 508-64-040 (Installation operation and maintenance requirements attached hereto). Meter readings shall be recorded monthly and this data shall be maintained and be made available to the Department of Ecology upon request. See enclosed form. Static water level (SWL) shall be measured at least once each month. Measurements shall be taken after the pump has been shut off and the water level in the well has been stabilized. The data shall be maintained and made available to Ecology upon request. However, Ecology's Water Resources Section (NW12O) shall be notified if the SWL is determined to be below the level normally recorded at that time of year. See enclosed form. Renton shall monitor the shallow and intermediate aquifers at least monthly to determine the best approach for maintaining Cedar River flows in the reach associated with the Maplewood Golf Course aquifers. The USGS gage I2II9000 (located in downtown Renton) shall be permanently maintained plus Renton shall establish and permanently maintain a least two additional upstream gaging stations- one in the Narrows area downstream of the golf course and another gaging station upstream of the influence of the Maplewood Golf Course aquifers. Renton shall notify the Department of Ecology NWRO Water Resources whenever a decrease in Cedar River flows is recorded between the upstream gage and any subsequent downstream gage. Prior to use of waters from the new wells, the gaging stations shall be in operation and an interim management plan detailing procedures for monitoring pumping and assuring that flows in the Cedar River are not decreased from pumping shall be submitted to lO Water Resources and approved. A long term management plan shall be submitted to NWRO Water Resources after 3 years of operating under the interim plan. The final management plan shall be approved by Water Resources prior to issuance of a certificate of water right. This permit is subject to the implementation of the minimum requirements established in the Interim Guidelines for Public Water Systems Regarding Water Use Reporting, Demand Forecastine Methodoloi*v and Conservation Programs, July 1990, which are attached. An estimate of water conservation savings as a percent reduction in average daily per capita consumption shall be provided to NWRO Water Resources. This estimate of water conservation savings will be replaced by evidence of actual water use reduction before a final water right certificate will be issued by the Department. A certificate of water right will not be issued until a final investigation is made. As part of the investigation Renton shall submit collected data (as outlined in the Interim Guidelines) to this office.

REPORT OF EXAMINATION DESCRIPTION OF PROPOSED WORKS BEGIN PFGJECT BY THIS DATE: PROXCT 9Y THIS DATE: WATER PUT YO PULL USE BY THIS DATE: 1 year from permit issuance 3 years from permit issuance 6 years from permit issuance REPORT \ The application was received on 1-2-86. It requests 1600 gpm (gallons per minute) from a well for Municipal Supply. Notice was published in the Valle Daily -News on February 7 and 14, 1986. No protests were filed within the 30 day protest period. The well covered by this application is known as well #12. Renton has submitted eight applications which are pending. This report will cover the issues involving five of the applications dealing with wells 10, 11, 12, and 17 as they reflect similar conditions. On March 9, 1988 Renton requested a Temporary Permit to drill and test wells located within the Maplewood Golf Course. The Temporary Permit was issued on March 14, 1488. During the time Renton's applications were pending evaluation, several letters of concern were received. The following is a brief summary of the concerns: Seattle Water Department raised questions during the environmental review process of Renton's Water System Plan. They want to know what studies were made to show that the Maplewood Golf Course wells were not hydraulically Iinked to the Cedar River and how might the wells and delivery facilities impact Seattle's pipeline in the vicinity. Sam Paffile, area developer, wants Renton to document that additional water is really needed and that the wells will not draw from an aquifer interrelated with the Cedar River. Mr. Paffile also wants Renton to take a serious look at conservation measures to curb additional water right acquisitions. The Muckleshoot Indian Tribe requests a thorough analysis of the interaction between the aquifer in which the wells are developed and flows of the Cedar River. They also want to see better conservation measures. These issues will be addressed in detail later in the report. Renton has complied with SEPA requirements with regard to the development of wells 10,11,12, and I7. INVESTIGATION A field visit was conducted on December 20, 1491 by Jerry Liszak, Regional Hydrogeologist, and Janet Jorg of the Northwest Regional Office. Ron Olsen, Utilities Engineer for Renton, and Geof Clayton, Hydrogeologist for Renton's consulting firm of RH2 Engineering, were present during the visit to Renton's well sites located in the Maplewood Golf Course. The site for well 12 is two miles east of Renton on the north side of Highway 169 (Maple Valley Rd.) in the Maplewood Golf Course. The well location described on the application correctly identified as being within the SEIJ4 SEI/4 of Section 16, Township 23N, Range 5E in King County. n's water system provides water to an area of 16 square miles.

His report of findings indicate there are three aquifers identified within the Maplewood Golf Course. A shallow or unconfined upper water table aquifer can be encountered to depths of 50 feet. Two deeper confined aquifers (known as the intermediate and the deep aquifers) occur at different locations within the golf course but they arc not superimposed over each other. The unconfined water table and intermediate aquifers are separated by a leaky aquitard making the intermediate aquifer semi -confined. The deep aquifer is encountered at the eastern end of the golf course and is a highly pressurized artesian aquifer. Exploratory drilling and testing did not encounter the deep aquifer under the intermediate aquifer in vicinity of well 11 or 17 or the observation well (OBW-1) nor was the intermediate aquifer encountered in the vicinity of the deep aquifer. Wells 10 and 12 are to be developed in the intermediate aquifer also. Recorded hydrostatic pressures of wells tapping the intermediate aquifer indicate no hydraulic connection with the deep Report Continued a^uifer. Wells 11 and 17 were drilled and developed in the intermediate aquifer. Well 11 was drilled to a depth 5 feet and well 17 was drilled to a depth of 346 feet. Based on the information obtained from the observation well (OBW-1) and wells 11 and 17 indicating water is available, Renton plans to drill well 10 and 12 near OBW-1 to be developed in the intermediate aquifer far a maximum quantity of 1600 gpm from each well. Approval of this application would carry conditions for proper well construction and adequate testing. Until Regional Water Plans are established as set forth by the Chelan Agreement, Ecology implemented interim policies to address short term water needs of larger public water systems in growth areas. Therefore applications for wells 10, 11, 12, and 17 are considered with respect to Renton's needs up to year 2000. The long term water needs for Renton will be evaluated as part of a regional water resources planning process and will be affected by implementation of the Growth Management Act. To evaluate an application for water right, the applicant must provide documentation as to need and availability of water on an instantaneous basis and demonstrate the amount of water needed on an annual basis to satisfy all uses. Renton's Comprehensive Water System Plan (released in March 1992) addresses their need to satisfy Department of Health(DOH) peak demand requirements. Renton shows they are 8,577 gpm short of DOH requirements, thus the instantaneous quantities associated with wells 10,11, 12, and 17 are requested to reduce deficiencies. The Water System Plan doesn't address needs based on actual consumption per capita or ,yearly consumption rates. By request, Renton provided water consumption figures for 1989 and 1991 which show they used less than 8,000 af/yr (acre feet per year). The population for 1991 as reported to DOH was 35,360 and the number of connections was 11,735. Figuring current consumption (8000 aflyr) plus adding annual growth rate of 1.8% (from King County Annual Growth Report for Renton area) up to the year 2000 places the annual quantity at 9088 acre-feet which is below the yearly amount already granted by existing rights (14,809 acre-feet). Therefore the applications concerning wells 10, 11, 12, and 17 will not be considered for any additional annual quantity. Ecology's interim policies do allow public water systems to increase the ability and flexibility of the systems to meet demands within existing y amounts for that interim period until regional water resources plans are accepted. Ecology will monitor ton's consumption and growth over the next six to eight years for possible adjustments through future permitting actions. As well 11 is recommended for a reduced quantity of 2500 gpm, the quantities considered for the applications pertaining to well 11 are 1600 gpm for G1-24781 and 900 gpm for G1-25396. Application GI -25397 for well 1.7 will be considered fora reduced quantity of 1500 gpm. Application G1-24783 for well 10 is considered for a maximum quantity of 1600 gpm and application G1-24782 for well 12 is considered for a maximum of 1600 gpm. The yearly volume that could be allocated from each application would be calculated at 70/0 of continuous pumping, with the stipulation that total withdrawal from all Renton's sources could not exceed the city's existing water right certificates (14,809 affyr). Ecology's interim policies also require public water systems to make the maximum use of conservation. Renton's current conservation plan identifies a 6.5% reduction in water use with implementation of the various components. Many measures are already in effect with the remainder scheduled for implementation within the corning year. Tice conservation plan and implementation is consistent with Ecology's Interim Guidelines for Public Water Systems. Ecology needs to monitor the effects of conservation measures on water consumption over the next few years. Review of office records indicates three downstream rights an the Cedar River which total 3.02 c€s (cubic feet per second). One right was issued to Northwest Water Co. in the amount of 1.0 cfs for the community of Kenneydale, which is now served by Renton. Field and office investigation show no wetlands in the area that would be adversely affected by the proposed withdrawals from well 12. CONSIDERATION OF OBJECTIONS ree proponents submitting concerns on Renton's new applications request analysis of interaction between Iaplewood Golf Course wells and flows in the Cedar River. The hydrogeologist's review indicates that wells 10, 11, 12, and 17 should be considered in hydraulic continuity with the Cedar River. The wells are developed in the semi -confined intermediate aquifer and pumping from the wells will induce leakage from the unconfined shallow aquifer. As rate of leakage has not been quantified o C.r%ov nC CVA%I11,1hT1nA1 -A_ No n1_'U7A'i Report Continued and the interrelationship is complex, our hydrogeologist recommends long term monitoring of the shallow and intermediate aquifers. Renton must show that pumping the wells will not decrease Cedar River flows to be in compliance with the intent of the Cedar-Sammamish Instream Resource Protection Program (WAC 173-508). Renton would be required to prepare an interim management plan detailing procedures for monitoring pumping and assuring that flows in the river are not decreased by use of wells 10, 11, 12, and IT The plan would need to be approved by Water Resources prior to beneficial use of water from the wells. An ongoing management plan would be required before a certificate of water right could issue. To aid monitoring of Cedar River flows, the USGS gage 12119000 located in downtown Renton would be permanently maintained plus Renton would be required to establish and permanently maintain at least two additional upstream gaging stations- one in the Narrows area downstream of the golf course and another gaging station upstream of the influence of the Maplewood Golf Course aquifers. A second issue raised is whether Renton really needs additional water rights. As earlier stated in the report Renton is not currently meeting DOH peak flow requirements; therefore Renton does need additional water rights for peak instantaneous quantities. Approval of the applications for wells 10, 11, 12, and 17 would help Renton toward meeting DOH requirements. Renton would also have the flexibility to better manage their entire system for peak daily demands while providing alternate sources of water should contamination occur in the downtown well field. Our analysis indicates that Renton has been granted sufficient water rights in terms of annual quantities to meet consumption demands beyond the year 2000. Consequently the applications covering wells 10, 11, 12, and 17 are only being considered for additional instantaneous quantities and not additional annual quantities. A third concern involves Renton's Comprehensive Water System Plan and Conservation Plan. It is felt that Renton is not conserving water to offset the need for additional water. Renton has provided information showing that conservation measures have and are being implemented which will reduce but not completely eliminate the need for additional water. The water system plan illustrates the effect of full conservation implementation on reduction of water consumption. In evaluating the applications for wells 10, 11, 12, and 17, instantaneous quantities and total consumption figures used to forecast Renton's needs until the year 2000 were based on average daily demands including aggressive conservation measures. Approval of Renton's applications would carry conditions to monitor actual consumption quantities, population, and service connections to be analyzed prior to certificate of water right issuance for effective conservation implementation and growth projections. In order to approve an application for permit, the following tests must be met: water is available for appropriation, water must be for a beneficial use, water use is not detrimental to public interest, and the use will not adversely affect existing rights. Taking into account the concerns expressed by the City of Seattle, Mr. Paffile, and the MuckIeshoot Indian Tribe all four tests are answered in the affirmative. The quantities as recommended in this report are adequately conditioned to assure protection of existing rights including instream flows and to assure that the proposed use will not be detrimental to the public interest. The tests conducted on observation wells, and wells 11 and 17, show water is available for appropriation and that the use for municipal supply is a beneficial use. CONCLUSION In accordance with Section 90.03 (and 90.44 RCW), I find that there is water available for this beneficial appropriation from the source in question and the appropriation as recommended will not impair existing rights or be detrimental to the public welfare. Therefore, permit should issue subject to existing rights and indicated provisions. A permit should issue for well 12 for a maximum quantity of 1600 gpm 1792 aflyr (based on 70% continuous pumping) and not cumulative to existing rights for municipal supply. Total annual withdrawal from this allocation (G1-24782) and all rights held by Renton shall not exceed 14,809 acre feet. The amount of water granted is a maximum limit that shall not be exceeded and the water user shall be entitled only to that amount of water within the specified limit that is beneficially used and required for the actual crop grown on the number of acres and place of use specified. A well log of the completed well shall be submitted by the driller to the Department of Ecology within thirty (30) days of completion of this well. This well log shall be complete and all information REPORT OF EXAMINATION -5- No. GI -24782 Report Continued concerning the static water level in the completed well, in addition to any pump test data, shall be submitted is obtained. Installation and maintenance of an access port as described in Ground Water Bulletin No. 1 is required. An air line and gauge may be installed in addition to the access port. All water wells constructed within the state shall meet the minimum standards for construction and maintenance as provided under RCW 18.104 (Washington Water Well Construction Act of 1971) and Chapter 173-160 WAC (Minimum Standards for Construction and Maintenance of Water Wells). Static water level (SWI-) shall be measured at least once each month. Measurements shall be taken after the pump has been shut off and the water level in the well has been stabilized. The data shall be maintained and made available to Ecology upon request_ However, Ecology's Water Resources Section (NWRG) shall be notified if the SWL is determined to be below the level normally recorded at that time of year. See enclosed form. An approved measuring device shall be installed and maintained in accordance with RCW 90.03,360, WAC 508- 64-020 through WAC 508-64-040 (Installation o eratian and maintenance re uirements attached hereto).

See enclosed form, The aquifer test shall be conducted under the supervision of a professional ground water consultant. The well shall be tested at a constant rate no less than the maximum design rate at which the well source will be used. WRIS Information Bulletin 30 (copy enclosed) shall be used as a guideline for designing and conducting the aquifer test. For water table aquifers, pumped water produced during the test shall be routed away from all wells and discharged such that this water will not recharge the drawdown cone during the test. Pumping during the test shall be, conducted for a minimum of 24 hours, with stabilization of the pumping well level occurring for at least the last 4 of those hours. Stabilization is defined as a drop in water level of han or equal to 0.1 feet drawdown per hour during pumping. For water table (unconfined) aquifer conditions, the test shall be conducted for 72 hours or until a minimum of 4 hours of drawdown has been detected in an observation well, whichever is shorter. At the completion of pumping, recovery data shall be collected from all wells until the pumped well achieves either 95% recovery, or its•water level is within 0.5 feet of static water level, whichever takes longer. The test must be designed and conducted to determine the following: a. The distance and time drawdown response within the producing aquifer to the proposed ground water withdrawal. To accomplish this, an observation well completed in the same aquifer and within a reasonable distance, shall be shut off and monitored for drawdown and recovery during the aquifer test. b. Aquifer transmissivity. C, Aquifer storage coefficient or specific yield. d. The effect of the proposed ground water withdrawal on existing ground water and surface water users. This shall include the potential effect of the withdrawal on local wetlands, springs, streams and lakes. Specifically it must be shown that the proposed ground water withdrawal will have no effect upon Cedar River flows_ The following outlines sampling and analysis requirements specified by the Washington State Department of Health. This section has been included to decrease the likelihood that applicants will need to perform a second test in order to comply with requirements of that agency. samples must be collected from the well using proper sampling procedures and analyzed by a laboratory certified by the Department of Health. A water sample shall be collected within the last 15 minutes of pumping and analyzed for the water quality test(s) outlined below, as well as any other required by the Department of Health.

WATEFI PUT TO FULL USE BY TI -48 GATE: Started 3 years from permit issuance 6 years from permit issuance REPORT l:�I11.(1".Celli 0 o. The application was received on 2-23-89. It requests 3000 gpm (gallons per minute) from a well for Municipal Supply. Notice was published in the Valles Daily News on March 29 and April 5, 1989. No protests were filed within the 30 day protest period - On March 9, 1988 Renton requested a Temporary Permit to drill and test wells located within the Maplewood Golf Course. The Temporary Permit was issued on March 14, 1988. During the time Renton's applications were pending evaluation, several letters of concern were received. The following is a brief summary of the concerns: 1. Seattle Water Department raised questions during the environmental review process of Renton's Water System Plan. They want to know what studies were made to show that wells 11 and 17 were not hydraulically linked to the Cedar River and how might the wells and delivery facilities impact Seattle's pipeline in the vicinity. Sam Paffile, area developer, wants Renton to document that additional water is really needed and that the wells will not draw from an aquifer interrelated with the Cedar River- Mr- Paffile also wants Renton to take a serious look at conservation measures to curb additional water right acquisitions. 3. The Muckleshoot Indian Tribe requests a thorough analysis of the interaction between the aquifer in which the wells are developed and flows of the Cedar River. They also want to see better conservation measures_ Theseissues will be addressed in detail later in the report Renton has complied with SEPA requirements with regard to the development of wells 11 and 17. A Mitigated Declaration of Non Significance was issued by Renton on May 4, 1988. The well covered by this application is known as well #17. Renton has two pending applications for a well (known as well #11) located within 50 feet from well 17. Application G1-24781 for well 11 was filed in 1986 for 1600 gpm and G1-25396 requesting 1400 gpm was filed in 1989. As wells 11 and 17 are in close proximity and share similar issues, this report will address and evaluate all three applications (G1-24781, G1-25396, and G1-25397) which pertain to the wells. INVESTIGATION A field visit was conducted on December 20, 1991 by Jerry Liszak, Regional i- Iydrogeologist, and Janet Jorg of the Northwest Regional Office. Ron Olsen, Utilities Engineer for Renton, and Genf Clayton, Hydrogeologist for Renton's consulting firm of RH2 Engineering, were present during the visit to Renton's well sites located in the Maplewood Golf Course. The site for wells I1 and 17 is two miles east of Renton on the north side of Highway 169 (Maple Valley Rd.) Maplewood Golf Course. The applications correctly identify the well locations as being within the N}ll4 Section 21, Township 23N, Range 5E of King County. Renton's water system provides water to an area of 16 square miles. The current system consists of 6 wells located in the downtown area and one artesian spring. There are 5 metered interties with Seattle for emergency REPORT OF EXAMINATION -2- No. G1-25397 Report Continued supply plus emergency intertie with Kent. Renton has one wholesale customer-L.akeridge Bryn Mawr Water District. Six reservoirs currently provide storage for Renton with another under construction.

Well 11 was drilled in August 1988 to a depth of 345 feet by 16 inches in diameter. We]] 17 was constructed at the same time to a similar depth (346 feet) but with a larger casing diameter (20 inches). The two wells are 50 feet apart. Regional Hydrogeologist, Jerry Liszak, reviewed data submitted by the applicant's consultants and other pertinent data relating to hydrogeology of the area- His review and report of findings indicate that both wells REPORT OF EXAMINATION -3- No. G1,25397 Report Continued id 17 are developed in the same aquifer (referred to as the intermediate aquifer) and are considered a well similar depth, close proximity, and same aquifer). Quoted in pan, the hydrogeologist review states,. Wells No. 11 and 17 were each tested using short term step rate and 24 hour constant rate pumping. The test results indicate that the transmissivity of the aquifer is between 45,000 and 60,000 gallons per day per foot of drawdown. The storage coefficient is approximately .005 which indicated the aquifer is confined. A recharge boundary was encountered after approximately 110 minutes of pumping in the 24 hour tests for both wells 11 and 17. Based on this and an understanding of the local geology, the recharge is assumed to be from leaky conditions in the hydrogeologic strata, or the lower permeability zone known as the aquitard, between the shallow and intermediate aquifers. Based on the test results, the recommended pumping rate for Well No. 11 is 2,500 gpm and the recommended pumping rate for Well No_ 17 is 1,500 gpm. It is calculated that well interference between the two wells will add between 30 and 50 feet of drawdown in each well depending on pumping rates and duration. Renton has not used either well to date as they are waiting for a decision an the water right applications, if approved, the City will proceed with funding for construction of a pumping station and distribution lines to the wells. Until Regional Water Plans are established as set forth by the Chelan Agreement, Ecology implemented interim policies to address short term water needs of larger public water systems in growth areas. Therefore applications for wells 11 and 17 are considered with respect to Renton's needs up to year 2000. The long terns water needs for Renton will be evaluated as part of a regional water resources planning process and will be affected by implementation of the Growth Management Act. To evaluate an application for water right, the applicant must provide documentation as to need and availability of water on an instantaneous basis and demonstrate the amount of water needed on an annual basis to satisfv a " �cs. Renton's Comprehensive Water System Plan (released in March 1992) addresses their need to satisfv tment of Health(DOH) peak demand requirements. Renton shows they are 8,577 gpm short of DON r rements, thus the instantaneous quantities associated with wells 11 and 17 are requested to reduce deficiencies, The Water System Plan doesn't address needs based on actual consumption per capita or yearly consumption rates. By request, Renton provided water consumption figures for 1989 and 1991 which show they used less than 8,000 af/yr (acre feet per year). The population for 1991 as reported to DOH was 35,360 and the number of connections was 11,735. Figuring current consumption (8000 af/yr) plus adding annual growth rate of 1.8% (from King County Annual Growth Report for Renton area) up to the year 2000 places the annual quantity at 9088 acre-feet which is below the yearly amount already granted by existing rights (14,809 acre-feet). Therefore 111e applications concerning wells 11 and 17 will not he considered for any additional annual quantity. Ecology's interim policies do allow public water systems to increase the ability and flexibility of the systems to meet demands within existing yearly amounts for that interim period until regional water resources plans are accepted. Ecology will monitor Renton's consumption and growth over the next six to eight years for possible adjustments through future permitting actions. As well 11 is recommended for a reduced quantity of 2500 gpm, the quantities considered for the applications pertaining to well 11 are 1600 gpm for G1-24781 and 900 gpm for G1-25396. Application GI -25397 for well 17 will be considered for a reduced quantity of 1500 gpm. The yearly volume that could be pumped from each application would be calculated at 70% of continuous pumping, with the stipulation that total withdrawal from all Renton's sources could not exceed the city's existing water right certificates (14,809 af/yr). Ecology's interim policies also require public water systems to make the maximum use of conservation. Renton's current conservation plan identifies a 6.5% reduction in water use with implementation of the various components. Many measures are already in effect with the remainder scheduled for implementation within the coming year. The conservation plan and implementation is consistent with Ecology's Interim Guidelines for Public Water Systems_ Ecology needs to monitor the effects of conservation measures on water consumption o • he next few years. R_ -.-w of office records indicates three downstream rights on the Cedar River which total 3.02 cfs (cubic feet per second)_ One right was issued to Northwest Water Co. in the amount of 1.0 cf.,; for the community of Kenneydale, which is now served by Renton. Report Continued Field and office investigation show no wetlands in the area that would be adversely affected by the proposed withdrawals from wells 11 and 17. CONSIDERATION OF OBJECTIONS All three proponents submitting concerns on Renton's new applications request analysis of interaction between wells 11 and 17 and flows in the Cedar River. The hydrogeologist's review indicates that wells 11 and 17 should be considered in hydraulic continuity with the Cedar River. The wells are developed in the semi -confined intermediate aquifer and pumping from the wells will induce leakage form the unconfined shallow aquifer. As rate of leakage has not been quantified, our hydrogeologist recommends long term monitoring of the shallow and intermediate aquifers. Renton must show that pumping the wells will not decrease Cedar River flows to be in compliance with the intent of the Cedar- Sammamish Instream Resource Protection Program (WAC 173-508). Renton would be required to prepare an interim management plan detailing procedures for monitoring pumping and assuring that flows in the river are not decreased by the use of wells 11 and 17. The plan would need to be approved by Water Resources prior to beneficial use of water from the wells. An ongoing management plan would be required before a certificate of water right could issue. To aid monitoring of Cedar River flows, the USGS gage 12119000 located in downtown Renton would be permanently maintained plus Renton would be required to establish and permanently maintain at least two additional upstream gaging stations- one in the Narrows area downstream of the golf course and another gaging station upstream of the influence of the Maplewood Golf Course aquifers. A second issue raised is whether Renton really needs additional water rights. As earlier stated in the report Renton is not currently meeting DOH peak flow requirements; therefore Renton does need additional water rights for peak instantaneous quantities. Approval of the applications for wells 11 and 17 would help Renton toward meeting DOH requirements. Renton would also have the flexibility to better manage their entire system for peak daily demands while providing alternate sources of water should contamination occur in the downtown well field. Our analysis indicates that Renton has been granted sufficient water rights in terms of annual quantities to meet consumption demands beyond the year 2000. Consequently the applications covering wells 11 and 17 are only being considered for additional instantaneous quantities and not additional annual quantities. A third concern involves Renton's Comprehensive Water System Plan and Conservation Plan. It is felt that Renton is not conserving water to offset the need for additional water. Renton has provided information showing that conservation measures have and are being implemented which will reduce but not completely eliminate the need for additional water_ The water system plan illustrates the effect of full conservation implementation on reduction of water consumption. In evaluating the applications for wells 11 and 17, instantaneous quantities and total consumption figures used to forecast Renton's needs until the year 2000 were based on average daily demands including aggressive conservation measures. Approval of Renton's applications would carry conditions to monitor actual consumption quantities, population, and service connections to be analyzed prior to certificate of water right issuance for effective conservation implementation and growth projections. In order to approve an application for permit, the following tests must be met: water is available for appropriation, water must be for a beneficial use, water use is not detrimental to public interest, and the use will not adversely affect existing rights. Taking into account the concerns expressed by the City of Seattle, Mr. Paffite, and the Muckleshoot Indian Tribe all four tests are answered in the affirmative. The quantities as recommended in this report are adequately conditioned to assure protection of existing rights including instream flows and to assure that the proposed use will not be detrimental to the public interest. The pump tests show water is available for appropriation and that the use for municipal supply is a beneficial use. CONCLUSION In accordance with Section 90.43 (and 90.44 RCW), I find that there is water available for this beneficial appropriation from the source in question and the appropriation as recommended will not impair existing rights or be detrimental to the public welfare. Therefore, permit should issue subject to existing rights and indicated provisions. RECOMMENDATIONS A permit should issue for well 17 at a reduced quantity of 1500 gpm (1680 acre feet per year based on 70% continuous pumping and not cumulative to existing rights) for municipal supply. Report Continued —,.at annual withdrawal from this allocation (G1-25397) and all rights held by Renton shall not exceed 14,809 feet. An approved measuring device shall be installed and maintained in accordance with RCW 90.03.360, WAC 508- 64-020 through WAC 508-64-040 (Installation, operation and maintenance requirements attached hereto). Meter readings shall be recorded monthly and this data shall be maintained and be made available to the Department of Ecology upon request. See enclosed form. Static water level (SWL) shall be measured at least once each month. Measurements shall be taken after the pump has been shut off and the water level in the well has been stabilized. The data shall be maintained and made available to Ecology upon request. However, Ecology's Water Resources Section (NWRO) shall be notified if the SWL is determined to be below the level normally recorded at that time of year, See enclosed form. Renton shall monitor the shallow and intermediate aquifers at least monthly to determine the best approach for maintaining Cedar River flows in the reach associated with the Maplewood Golf Course aquifers. The USGS gage 12119000 (located in downtown Renton) shall be permanently maintained plus Renton shall establish and permanently maintain a least two additional upstream gaging stations- one in the Narrows area downstream of the golf course and another gaging station upstream of the influence of the Maplewood Golf Course aquifers. Renton shall notify the Department of Ecology NWRO Water Resources whenever a decrease in Cedar River flows is recorded between the upstream gage and any subsequent downstream gage. Prior to use of waters from the new wells, the gaging stations shall be in operation and an interim management plan detailing procedures for monitoring pumping and assuring that flows in the Cedar River are not decreased from pumping shall be submitted to N"RO Water Resources and approved. g term management plan shall be submitted to NWRO Water Resources after 3 years of operating under the interim plan. The final management plan shall be approved by Water Resources prior to issuance of a certificate of water right. This permit is subject to the implementation of the minimum requirements established in the Interim Guidelines for Public Water Systems Regarding Water Use Reporting, Demand Forecasting Methodolog and Conservation Programs, July 1940, which are attached. An estimate of water conservation savings as a percent reduction in average daily per capita consumption shall be provided to NWRO Water Resources. This estimate of water conservation savings wit] be replaced by evidence of actual water use reduction before a final water right certificate will be issued by the Department. A certificate of water right will not be issued until a final investigation is made. As part of the investigation Renton shall submit collected data (as outlined in the Interim Guidelines) to this office. REPORT BY:Cc-�r_4 11�1-14; DATE: �,`�.

Applicant is advised that notice of proof of appropriation of water (under which final certificate of water right issues) should not be filed until the permanent diversion facilities have been installed together with a mainline system capable of delivering the recommended quantity of water to an existing or proposed distri- bution system within the area to be served. Use of the waters to be appropriated under this application will be for a public ater supply. State Board of Health rules require every owner of a public water apply to obtain written approval from the Assistant Secretary, Division of Health ,riot to any new construction or alterations of a public water supply. The appli- cant is advised to contact the Washington State division of Health, Public Health Building No. 4, Thurston Airdustrial Center, Olympia, with regard to the need for compliance. "A suitable measuring device shall be installed and maintained in accordance with WAC 508-64-020 through WAC 508-64-040." (Installation, operation and maintenance requirements attached hereto.) It is noted that the well site and/or water transmission facilities are not wholly located upon the land owned by the applicant. Applicant is, accordingly, advised that the issuance of permit by this Department for appropriation of the waters in question does not convey a right of access to, or other right to use, land which the applicant does not legally possess. Obtainment of such right is a private matter between applicant and owner of that land.

Liszak, Actifig Section Manager, Water Resources SUPERSEDING PERMIT 2 G1-25397 Appendix F SYSTEM MAPS Appendix G CROSS CONNECTION CONTROL PLAN INTRODUCTION PURPOSE: The purpose of the City of Renton's Cross Connection Control Plan is to document the planning, implementation, codes and policies of the City's Cross Connection Control Program. The City has an on-going cross connection control program with authority established by City Ordinance 4312, which complies with WAC 246-290-490 and with the Department of Health's requirements. An Engineering Specialist II with the Water Utility section, with a State certification as Cross -Connection Control Specialist administers the program and implements City codes, policies, standard operating procedures and other elements related to the program. The City's program follows and complies with the minimum elements of a cross connection control program identified in WAC 246-290-490 (3) as listed below: Element 1: The purveyor shall adopt a local ordinance, resolution, code, bylaw, or other written legal instrument... An Ordinance No. 4312 was adopted by City Council On May 13, 1991, amending City Codes on "Water, Health and Sanitation" by adding a Cross -Connection Control section, to protect the health of water customers and the potability of the water in the distribution system. The ordinance established the City's authority for implementing the cross -connection control program. The following Renton Municipal Code (RMC) meets the requirements of Element 1 and its subsections: RMC 4-6-020 CROSS CONNECTION CONTROL STANDARDS: A PURPOSE: 1. National standards of safe drinking water have been established. The City, as a water purveyor, has the primary responsibility for preventing water from unapproved sources, or any other substances, from entering the public potable water system. (Ord. 4312, 5-13-1991) 2. This Section is to protect the health of the water consumer and the potability of the water in the distribution system. This is accomplished by eliminating or controlling all actual (direct) and potential (indirect) cross connections between potable and nonpotable systems through the use of approved backflow prevention assemblies. B APPLICABILITY: This Chapter applies throughout the water service area of the City. It applies to all systems installed prior to or after its enactment. Therefore, anyone wanting or using water from the City is responsible for compliance with these regulations and shall be strictly liable for all damage incurred as a result of failure to comply with the express terms and provisions contained herein. C AUTHORITY: The Administrator of the Department of Public Works will administer the provisions of the Chapter. He/she will designate cross connection specialists and propound all needful rules and regulations to implement these provisions. The Water Utility Section of the Utility Systems Division will be responsible for monitoring and inspecting all existing cross connection assemblies and for keeping all records generated by the cross connection control program. The Plan Review Section of the Development Services Division of the Department of Community and Economic Development will be responsible for reviewing all new and revised plans for cross connections. (Ord. 5450, 3-2-2009) D INSTALLATION OF BACKFLOW PREVENTION ASSEMBLIES: Backflow prevention assemblies required by this Chapter must be installed so as to be readily accessible for maintenance and testing. All assemblies shall be connected at the meter, the property line when meters are not used, or within any premises where, in the judgment of the City Cross Connection Control Specialist, the nature and extent of activity on the premises or the materials used or stored on the premises could present a health hazard should a cross connection occur. This includes: 1. Premises having an auxiliary water supply. 2. Premises having internal cross connections that are not correctable, or intricate plumbing arrangements which make it impractical to ascertain whether or not cross connections exist. 3. Premises where entry is restricted so that inspections for cross connections cannot be made with sufficient frequency or at sufficient short notice to assure that cross connections do not exist. 4. Premises having a repeated history of cross connections being established or re-established. 5. Premises on which any substance is handled under pressure so as to permit entry into the public water system, or where a cross connection could reasonably be expected to occur. This includes the handling of process waters and cooling waters. 6. Premises where materials of a toxic or hazardous nature are handled such that if backsiphonage should occur, a health hazard may result. 7. Hospitals, mortuaries, clinics. S. Laboratories. 9. Piers and docks. 10. Sewage treatment plants. 11. Food or beverage processing plants. 12. Chemical plants using a water process. 13. Metal plating industries. 14. Petroleum processing or storage plants. 15. Radioactive material processing plants or nuclear reactors. 16. Car washes. 17. Process waters or cooling towers. 18. Fire sprinkler systems. 19. Irrigation systems. 20. Solar hot water systems. 21. Others specified by the Administrator of the Department of Planning/Building/Public Works. E TYPES OF BACKFLOW PREVENTION ASSEMBLIES REQUIRED: Specific types of backflow prevention assemblies are required in the following conditions: 1. An air -gap separation or reduced principle backflow prevention assembly shall be installed where the water supply may be contaminated by industrial waste of a toxic nature or any other contaminant which would cause a health or system hazard. 2. An air gap must be used between a potable water supply and sewer connected wastes. 3. Lawn sprinkler or irrigation systems, which are supplied by City water only, shall be required to have a pressure vacuum breaker. If such system contains an auxiliary pump or is subject to chemical additives a double-check valve assembly, air -gap separation or a reduced pressure principle backflow prevention assembly will be required. F RESPONSIBILITIES OF OWNER AND UTILITY: 1. Water Utilities Section: a. The Water Utilities Section will perform evaluations and inspections of plans/or premises of all existing facilities and inform the owner, by letter, of any corrective action deemed necessary, the method of achieving the correction and the time allowed for the correction to be made. b. The Water Utilities Section shall insure that all backflow prevention assemblies are tested annually to insure satisfactory operation. c. The Water Utilities Section shall inform the owner, by letter, of any failure to comply by the time of the first reinspection. An additional fifteen (15) days will be allowed for the correction. In the event the owner fails to comply with the necessary correction by the time of the second reinspection, the Water Utilities Section will inform the owner, by letter, that the water service to the owner's premises will be terminated within a period not to exceed five (5) days. d. If the Water Utilities Section determines at any time that a serious threat to the public health exists, the water service will be terminated immediately and without notice. 2. Pian Review Section: On new installations the Plan Review Section will provide on-site evaluation and/or inspection of plans in order to determine if cross connections exist and what type of backflow preventer, if any, will be required before a water meter permit can be issued. 3. Owner: a. The owner shall be responsible for the elimination or protection of all cross connections on his property. b. The owner, whether notified by the City or not, shall at his expense install, maintain and have tested by a certified tester any and all backflow preventers on his premises. c. The owner shall return to the City the assembly test reports within thirty (30) days after receipt of the yearly test notification. d. The owner shall inform the Water Utilities Section of any proposed or modified cross connections. e. Owners who cannot shut down operation for testing of assemblies must provide bypass piping with an additional backflow assembly at their expense. f. The owner shall only install backflow preventers which are approved by the Washington State Department of Health. g. The owner shall install backflow preventers only in a manner approved by the Washington State Department of Health. h. The owner may be required to install a backflow preventer at the service entrance if a private water source is maintained on his premises, even if it is not cross connected to the City's system. i. Failure of the owner to cooperate in the installation, maintenance, repair, inspection and testing of backflow preventers required by this Section shall be grounds for the termination of water service or the requirements of an air -gap separation. G ANNUAL INSPECTION AND TESTING REQUIREMENTS: All reduced pressure principle backflow assemblies, double check valve assemblies, pressure vacuum breaker assemblies and air gaps installed in lieu of a backflow preventer shall be inspected and tested annually or more often when successive inspections indicate failure. All inspections and testing will be performed by a certified tester. The test reports shall be returned to the City within thirty (30) days after receipt of the yearly test notification. (Ord. 4312, 5-13-1991) 4 Element 2: The purveyor shall develop and implement procedures and schedules for evaluating new and existing service connections to assess the degree of hazard posed by the consumer's premises to the purveyor's distribution system and notifying the consumer ...... New Installations: As part of the City's review of an application for water service and for the issuance of a water meter permit for domestic, landscape irrigation, fire sprinkler system of for other water uses: 1. The Water Utility section reviews all pians for development and redevelopement projects, including plans for tenant improvements of existing and new buildings, and evaluates the cross -connection hazards. All new multi -family, commercial and industrial development and redevelopment projects are required to have "premise isolation" by having an approved Reduced -Pressure Backflow Assembly (RPBA) installed behind the domestic meter and as close as possible to the meter, conforming to the City's water utility standards details. The Water Utility may allow the installation of an approved Double Check Valve Assembly (DCVA) for premise isolation, after the review of the building plumbing plans and after verification that the use of the building is not considered as "severe or high -hazard' facilities per Table 9 of WAC 246-290-490. A Double Check Valve Assembly (DCVA) is required on a landscape irrigation meter and a Detector Double Check Valve Assembly (DDCVA) is required for a fire protection service. 2. The City's Building/Plumbing inspector evaluates the cross -connection hazards from the building internal plumbing and requires the installation of proper backflow prevention assemblies for in -premise isolation. The Water Utility coordinates its review of the plans with the Building/Plumbing inspector when the backflow prevention assemblies are used both for premise and for in -premise isolation. 3. The Public Works utility inspector inspects the installation of all backflow prevention assemblies installed outside of the buildings. The Building/Plumbing inspector inspects all backflow prevention assemblies installed inside the buildings. 4. Satisfactory backflow test reports must be submitted to the Water Utility for review prior to the final occupancy of the building. Periodic reevaluations: The Water Utility Cross -Connection Control Program manager periodically reevaluates connections and assess hazards as part of the preparation and submittal of the Annual Summary Report to the Department of Health. Connections are also evaluated and hazards assessed when they are brought to the attention of the Cross Connection Control Program Manager, for example during a tenant improvement project or when a building/plumbing inspector notices something of concern. Element 3: The purveyorshall develop and implement procedures and schedules for ensuring that: (i) Cross -connections are eliminated whenever possible (u) When cross -connections cannot be eliminated, they are controlled by installation of approved backflow preventers commensurate with the degree of hazard, and (iii) Approved backflow preventers are installed in accordance with the requirements of subsection (6) of this section. 1. The City's Cross -Connection Control Program endeavors to eliminate all actual or potential physical cross -connection where possible. An approved air -gap is required for a severe hazard facility such as the icing County Wastewater Treatment Plant. RPBA's are required for premise isolation for all high -hazard facilities and for all facilities listed in Table 9 of WAC 246-290-490. 3. The City has adopted codes and published standards details and procedures for the installation and testing of backflow prevention assemblies consistent with the "Cross -Connection Control Manual Accepted Procedure and Practice", latest edition. Element 4: The purveyor shall ensure that personnel, including at least one person certified as a CCS, are provided to develop and implement the cross -connection control program. The City's Cross -Connection Control Program manager is a State certified Cross -Connection Control Specialist. Several staff in the Water Utility section and Water Maintenance section are also State certified Cross - Connection Control Specialists and Backflow Assembly Testers. Element 5: The purveyor shall develop and implement procedures to ensure that approved backflow preventers relied upon to protect the public water system are inspected and/or tested (as applicable) under subsection (7) of this section. The Cross Connection Control Program Manager maintains current a database of backflow prevention assemblies installed within the water customers' premises and at the water meters. The program manager sends annual "Notice to Test" to owners of backflow prevention assemblies and reviews the tests reports submitted by State certified backflow assembly testers. The program manager notifies the owners by letter when an assembly fails the test and requires that the assembly be repaired or replaced and a satisfactory test report must be submitted to the City. The program manager inspects all new installation of backflow assemblies for premise -isolation. The Building/Plumbing inspector inspects the installation of assemblies inside the buildings. A hazard assessment is conducted as part of the inspection to ensure that protection is provided commensurate with the assessed degree of hazard. A State certified BAT inspects air gap, RPBA's, DCVA's, DDCVA's and all other approved assemblies and sends the test reports to the City. Element 6: The purveyor shall develop and implement a backflow prevention assembly testing quality control assurance program, including, but not limited to, documentation of BAT certification and test kit calibration, test report contents, and time frames forsubmitting completed test reports. The Cross Connection Control Program Manager reviews the test reports submitted by State certified BATS for completeness and accuracies. Test reports must be submitted within 30 days of completing the test. If information is missing on the report, or errors are found, the program manager notifies the testers to resubmit a revised report. The program manager may also inspect the assembly in question. The program manager requires that the testers submit copies of their current certification and their test kit calibration reports. This information in entered into the City database. A list of certified backflow device testers in the King County area is kept in the Cross Connection Control Program files. Copies of this list are made available to the public. A current list of backflow prevention assemblies approved for installation in Washington State is also kept in the program's files. Both of these lists are updated on a regular basis. Element 7: The purveyor shall develop and implement (when appropriate) procedures for responding to backflow incidents. This element is covered in the City of Renton Water System Emergency Response Plan and also in the Security - Terrorism Appendix. Each backflow incident is investigated by the City upon its discovery or knowledge. Reports of investigations and findings are sent to the Department of Health for each actual backflow incident. 6 The City Public Works staff has been trained on response to various emergencies including a contamination of water system through cross -connection. Element 8: The purveyor shall include information on cross -connection control in the purveyor's existing program for educating consumers about water system operation. The public education program may include periodic bill inserts, public service announcements, pamphlet distribution, notification of new consumers and consumer confidence reports. The City provides information on cross -connection through its website and trough the annual Water Quality Report. Public outreach and education are conducted through special events, such as Renton River Days and through regional participation with other Cities and Water purveyors. Element 9: The purveyor shall develop and maintain cross -connection control records including, but not limited to, the following (i) A master list of service connections and/or consumer's premises where the purveyor relies upon approved backflow preventers to protect the public water system from contamination, the assessed hazard level of each, and the required backflow preventer(s); (ii) inventory information on backflow preventers that protect the public water system including: (A) Approved air gaps installed in lieu of approved assemblies including exact air gap location, assessed degree of hazard, installation date, history of inspections, inspection results, and person conducting inspections; (B) Approved backflow assemblies including exact assembly location, assembly description (type, manufacturer, model, size, and serial number), assessed degree of hazard, installation date, history of inspections, tests and repairs, test results, and person performing tests; and (C) Approved AVBs used for irrigation system applications including location, description (manufacturer, model, and size), installation date, history of inspection(s), and person performing inspection(s). NO Cross -connection program summary reports and backflow incident reports required under subsection (8) of this section. 1. The City's Cross -Connection Control Program currently uses XC2 software and track the following information on each backflow prevention assembly and facility served with City water: level of hazard, type of backflow prevention assembly used, premise or in -premise use, location of assembly or air -gap, installation date, inspection history, test and repair history, test results, tester's information, inspection of assembly. 2. The City keeps records of all backflow incidents investigations and findings and of the annual summary reports. Element 10: Purveyors who distribute and/or have facilities that receive reclaimed water within their water service area shall meet any additional cross -connection control requirements imposed by the department in a permit issued under chapter 90.46 RCW. The King County Wastewater treatment plant used reclaimed water produced by the plant. There is an approved air -gap between the City's water supply and the domestic water tank owned by King County. The Boeing Customer Training Center has a support facility that uses reclaimed water for its cooling system, and there is an approved Double Check Valve Assembly at the City's domestic meter to the facility and a Reduced Pressure Backflow Assembly at the service branch to the cooling system.

Introduction This plan summarizes all the drinking water duality monitoring conducted by the City of Renton. The monitoring includes, operational parameters such as fluoride and chlorine; regulatory requirements such as volatile organics and inorganics, and aquifer management such as groundwater level measurement and contaminate detection. The document is divided into five sections. The fust section describes the City of Renton water system and treatment operations. The second section describes water quality monitoring for operations. Each parameter is listed and under each parameter is a paragraph that describes the parameter, sampling and analysis methods, sample locations, and recording and reporting. The third section describes water quality monitoring per regulation (regulatory monitoring). Each parameter (or parameter family) is listed and under each parameter is a paragraph that describes the required analytes, sampling locations, sampling and analysis methods, sampling frequency and recording and reporting. The fourth section describes aquifer management monitoring. Three objectives are listed and under each objective is a goal. The fifth section discusses current or upcoming water quality regulations that are currently, or soon to have , a significant impact on water utility operations at the staffing and or infrastructure level. Appendix A to this plan is the City of Renton's Coliform Monitoring Plan. Appendix B to this plan is the City of Renton's Stage 2 Disinfection & Disinfectants Byproducts Rule Compliance Monitoring Plan. II. Water System and Treatment The City of Renton water system provides water service to an area of approximately 16 square miles and 64,000 customers through 17,368 service connections and one wholesale customer, Skyway Water and Sewer District, via a single metered connection. The City's water supply sources include nine wells (RWA, RW -2, RW -3, PW -5A, PW -8, PW -9, PW -11, PW -12 and PW -17) and one artesian spring (Springbrook Springs). The City has an additional well, EW -3, available for emergency use. Wells RW -1, RW -2, RW -3, PW -8, PW -9 and EW -3 are located in Liberty Park and Cedar River Park and pump from the Cedar River Delta Aquifer. Wells PW -11, PW -12 and PW -17 are located on the Maplewood Golf Course and pump from the deep Maplewood Aquifer. Well PW -5A pumps from a deep aquifer located in the Kennydale area of north Renton. The City is a wholesale customer of Seattle Public Utilities (SPU). The City has six metered interties with SPU transmission mains, which are available to serve wholesale water to the Renton distribution system. The water distribution system serves the valley floor and five surrounding hills: West I Iill, I Iighlands, Renton Hill, Talbot Hill and Rolling Hills. There are 15 hydraulically distinct pressure zones, nine on-line booster pump stations and two standby booster pump stations located throughout the City. There are 10 reservoirs in the system and approximately 305 miles of water main in service. Gaseous chlorine or sodium hypochlorite is added to all of the City's sources for disinfection and sodium fluoride is also added to prevent dental caries / cavities. Sodium hydroxide is added at Wells RW -1, RW -2, RW -3, PW -8, PW' -9, and EW -3, as well as at Springbrook Springs, to raise the pH of the water delivered to the distribution system. The Maplewood treatment facility treats water from wells PW -11, PW -12, and PW - 17. The Maplewood Treatment Plant: (1) removes hydrogen sulfide by converting it to sulfate by adding oxygen (granular activated carbon is used as a catalyst), (2) removes manganese using green sand filters, and (3) converts ammonia in the water to nitrogen gas by reacting it with sodium hypochlorite in a contact basin. A sequestering agent (Aqua Mag) is used in Well 5A to treat for iron and manganese. Since there is also naturally occurring ammonia in the water at Well SA, the chlorine dosage is set to create monochloramines for disinfection. From an aesthetics perspective the existing treatment is marginal (taste, odor and staining problems still exist), therefore this source is used sparingly_ Aqua Mag is also added at the Mt Olivet Booster Pump Station, the West Hili Booster Pump Station, and Pressure -Reducing Valve (PRV) Station 20 in the Renton I Iill area for corrosion control because of the significant number of cast iron distribution pipelines in these areas. III. Monitoring For Operations A. Chlorine Parameters: Chlorine demand is calculated in mg/1, free chlorine residual is measured in mg/1 and total chlorine residual is measured in mg/l. Sampling and Analysis Methods: Free chlorine is measured continuously by analyzer at all sources. The analyzer data is recorded by SCADA and the results are stored in the SCADA System History database. Grab samples are collected and measured daily by water quality staff for free chlorine from each source that is operating when staff is present and at nine (9) sampling stations located throughout the distribution system. Free and total chlorine arc measured by water quality staff during compliance bac-t sampling at bac-t sampling stations located throughout the distribution system. Grab samples at the source and in the field are collected in a glass tube and analyzed using the DPD colorimetric method (Hach Methods 10069 and 10070) using a Hach Pocket Colorimeter II.

Aquifer Management Monitoring Goal: To provide an early warning of contaminates present in production well capture zones and to track the short term (seasonal) and the long term changes in the elevation of the aquifer water table. The City owns (owned) 58 monitoring wells which can be used to collect water samples and measure the elevation of the water table. Status of Monitoring Wells: In 2009 the City contracted with Pacific Groundwater Group to assess the state of the City's monitoring wells. Pacific Groundwater Group could not locate two wells, determined that two wells had been abandoned and four had been decommissioned. Pacific Groundwater Group provided the City with a list of recommended maintenance and upgrades to the monitoring wells to make them more secure and more usable. The City has hired Pacific Groundwater Group to provide a risk assessment of the aquifer; priorive the monitoring wells based on the outcome of the risk assessment, and repair and secure the monitoring wells. A. Downtown Aquifer Water Quality Goal: To sample the water quality of the downtown aquifer for contaminates which may reach our downtown drinking water wells. Past sampling has been sporadic. The City has contracted with Pacific Groundwater Group to perform a risk assessment of the downtown aquifer and prioritize the monitoring wells based on their probability of detecting a contamination event. Based on Pacific Groundwater Group's findings and staffing availability, the Water Utility will identify the monitoring wells to sample as well as the frequency of sampling. If contaminates are detected in a monitoring well, the Water Utility will conduct follow up sampling. The test results are entered into the Water Quality database. B. Downtown Aquifer Water Level Goal: To measure water levels in the downtown aquifer on a monthly basis, September - May and a bi- weekly basis June — August. The data is used to analyze the seasonal and long term changes in the water table. The measurements are entered in the Water Level database. The following monitoring wells are measured: MW -1, MW -10, MW -18, MW -20, MW -21, MW -305, MW -30D, MW -315, MW -31D, MW -34S, MW - 34D, OSP-9 & I IC -6I. Recently monitoring wells MW -27, MW -255 and MW -25D were added to this list. C. Maplewood Aquifer Water Level Goal: To measure water levels in the shallow and deep aquifers at the Maplewood Golf Course. The data is used to analyze the impact of production well pumping on the aquifers. The Water Utility has installed pressure transducers in several of the groundwater wells located in the Maplewood aquifers (MW -36S & D, MW -37S & D and MW -38S & D). The transducers measure pressure and temperature and are programmed to take a measurement every 10 minutes. The data is downloaded from the transducers and stored on the City of Renton's I I drive. Issues: The transducers breakdown frequently. The manufacturer re -designs the transducers on a regular basis and does not provide technical support for older models, which forces the Water Utility to often upgrade the transducers_ The program to manage and maintain the transducers is time consuming and expensive. At this time the Fater Utility is exploring other options for measuring groundwater levels in the shallow and deep Maplewood aquifers. VI. Water Quality Regulations of Current Significance to the City of Renton A. The Groundwater Rule The Groundwater Rule (GWR) was signed October 11, 2006 by EPA :'administrator Stephen L. Johnson; published in the Federal Register on November 08, 2006; adopted by the Washington State Department of Health on October 1, 2010, and placed into effect on November 1, 2010. A correction to the table on Analytical Methods For Source Water Monitoring was published in the Federal Register November 21, 2006. The rule builds upon the Total Coliform. Rule (TCR) by addressing the health risks of fecal contamination in groundwater sources used by public water system. The GWR applies to all Group A public water systems that: • Rely entirely on one or more groundwater sources. • Receive finished groundwater from another public water system. • Mix surface water sources (or groundwater under the direct influence of surface water) with groundwater. Systems that combine all of their sources before treatment are exempt from the rule. The GWR's risk-based strategy addresses risks through an approach that relies on four major components: • Periodic sanitary surveys of systems that require the evaluation of eight critical elements of a public water system and the identification of significant deficiencies (e.g., a well located near a leaking septic system); + Triggered source water monitoring when a system (that does not already treat drinking water to remove 99.99 percent (4 -log) of viruses) identifies a positive sample during its Total Coliform Rule monitoring and assessment monitoring (at the option of the state) targeted at high-risk systems; + Corrective action is required for any system with a significant deficiency or source water fecal contamination; and • Compliance monitoring to ensure that treatment technology installed to treat drinking water reliably achieves 99.99 percent (4 -log) inactivation or removal of viruses. City of Renton Action: Currently City of Renton water quality personnel collect source water samples, from sources in operation, when they collect coliform samples for compliance with the Total Coliform Rule. This allows immediate identification of E_ coli positive or negative source water samples in case the City finds a coliform positive sample in the distribution system. These source water samples count as triggered source water samples. If an E. coli positive sample is detected in a source water sample the Washington State Department of Health will direct the City to either take corrective action or take five additional source samples within 24 hours_ if E. coli continues to be present in source water samples the Department of Health will direct the City to take corrective action and issue public notification. In addition the Groundwater Rule increases the frequency of sanitary surveys from once every five years to once every three years if certain requirements are not met. The City of Renton is currently in the preliminary design phase of a chlorine contact system for wells PW -8, PW -9, RW -3 and Springbrook Springs to provide 4 -log treatment of viruses in conjunction with compliance monitoring. Once the system is approved by the Department of Health and placed into operation, the City will no longer have to meet the triggered source water monitoring requirements and will be allowed to maintain a sanitary survey frequency- of 5 years. However, the City will be required to perform compliance monitoring of the 4 log inactivation or removal of viruses and comply with corrective action and public notification as directed by DOH for compliance violations. Well,, RW -1, 2 & 3 receive 4 log treatment of viruses through the existing CTG pipeline installed in Liberty Park. `Fells PW -11, 12 & 17 receive 4 log treatment of viruses through the chlorine contact chamber operating at the Maplewood Treatment Plant. B. Stage 2 Disinfectants and Disinfection Byproducts Rule (Stage 2 DBPR) Published in the Federal Register on January 4, 2006 with an effective date of March 6, 2006. The Washington State Department of Health adopted the rule and began enforcement January 4, 2010_ The purpose of the rule is to increase public health protection by reducing the potential risk of adverse health effects associated with disinfection byproducts (DBPs) throughout the distribution system. Stage 2 DBPR Builds on the Stage 1 Disinfectants and Disinfection Byproducts Rule (Stage 1 DBPR) by focusing on monitoring for and reducing concentrations of two classes of DBPs—TTI IM and I L�15 in drinking water. Initial Distribution System Evaluation (IDSE) Stage 2 DBPR requires some systems to complete an IDSE to characterize DBP Ievels in their distribution systems and identify locations to monitor DBPs for stage 2 DBPR compliance. The Stage 2 DBPR bases 'ITHM and HAA5 compliance on a locational running annual average (LRAA) calculated at each monitoring location. The IDSE options are: Standard Monitoring, System Specific Study (SSS), 40/30 Certification (no IDSE monitoring requirements) and Very Small Svstem Waiver (no IDSE monitoring requirements) Major changes from Stage 1 DBPR to the Stage 2 DBPR include: • Consecutive systems now must monitor if any water they provide is treated with any type of chlorination or ozone, even if only the supplier uses it. i The number of samples served is now only related to population served and source type. + Sample locations are based on locations of highest TTI IM and I IAA5 averages based on both interim stage 2 DBPR monitoring during initial distribution system evaluation, if required, and Stage 1 DBPR monitoring. Large systems must include some Stage 1 DBPR locations. + Determining maximum contaminant level compliance now is based on the locational annual average. Compliance Dates: Schedule 1 systems (systems serving populations greater or equal to 100,000) must begin routine monitoring according to Stage 2 rule by April 1, 2012. Sampling requirements: Ground water systems serving populations of 100,000 — 499,999 must take 6 samples per quarter. Groundwater systems serving populations equal to or greater than 500,000 must take 8 samples per quarter. City of Renton Action: The City of Renton applied for and received 40/30 Certification and therefore is not required to complete an IDSE. Currently Renton samples once yearly, in summer, for 'I`l'HM and HAAS from 6 sites. Renton continues to comply with the 40/30 certification by maintaining TTHM at all sites below 40 micro -grams per liter and I IAA5 at all sites below 30 micro -grams per liter. At the time of this writing Renton is waiting for direction from DOH on how to prepare the Stage 2 DBPR Compliance Monitoring Plan. Renton is classified as a Schedule 1 system and must begin routine monitoring according to the Stage 2 DBP Rule by April 1, 2012. Renton will be required to sample at either 6 or 8 sites, depending on the combined population of the Seattle Public Utilities' water service area and the Renton Water Utility service area. C. Unregulated Contaminants Monitoring Rule 3 As proposed, UCMR 3 would require public water systems (PWSs) to monitor for 28 chemicals and two viruses_ All PWSs serving more than 10,000 people, and a representative sample of 800 PWSs serving 10,000 or fewer people, would be required to conduct Assessment Monitoring for 28 "List 1" chemicals during a continuous 12 -month period from January 2013 through December 2015. In addition, a targeted group of 800 PWSs serving 1,000 or fewer people would be required to conduct Pre -Screen Testing for two "Ust 3" viruses during a 12 -month period from January 2013 through December 2015. Contaminants listed are: 17-B-estradiol; 17-a-ethynylestradiol; 16-a-hydroxyestradiol; equilin; estrone; testosterone; 4 -androstene -3, 17-dione; 1,2,3-trichloropropane; 1,3 -butadiene; chloromethane; 1,1-dichloroethane; n-propylbenzene; bromomethanc; sec -butyl crimne; chlorodifluoromethane; bromochloromethane; 1,4 -dioxane; vanadium; molybdenum; colbalt; strontium; chlorate; perfluorooctane sulfonate; perfluorooctanoic acid; perfluorononanoic acid; perfluotohexane sulfonic acid; perfluoroheptanoic acid; perfluorobutane sulfonic acid; enteroviruses; noroviruses. City of Renton Action: The City is monitoring the development of this rule. Appendix A To Drinking Water Quality Monitoring Program Coliform Monitoring Plan The plan consists of six components: I.

Projecting a realistic future water demand is necessary for planning infrastructure projects and securing adequate water supply to meet future growth. 1.0 AVAILABLE DATA SOURCES This section summarizes the available sources of information used to develop the demographic and water demand projections summarized in Chapter 3 of the City's Water System Plan Update Report. 1.1 Puget Sound Regional Council Population, employment, and household projections developed by the Puget Sound Regional Council (PSRC) form the backbone of the demographic and population projections for the Water System Plan Update. The PSRC Population, Households, and Employment Forecast database contains historical and future year estimates of key demographic and employment values for the Puget Sound region by forecast analysis zone (FAZ). FAZs are the geographic units used by the PSRC to report its small area forecasts of population, households, and employment. They are built up from traffic analysis zones (TAZs), with each FAZ containing between 1 to 20 TAZs. Data provided in the PSRC database is available in ten-year increments, starting with 1980 and extending through 2040. Because the City's retail water service area (RWSA) and pressure zone boundaries do not coincide with the PRSC FAZ boundaries or TAZ boundaries, City staff allocated the key demographic and employment variables (total households, total population, total employment) to each pressure zone within the RWSA using geographic information system (GIS) techniques. The City provided the resulting demographic projections in excel spreadsheet format through year 2040. 1.2 Historical Account and Water Production/Consumption Data The City provided historical account information by pressure zone and account type for the years of 2004 through 2010. In addition, the City provided historical water consumption data by customer class and production data for years 2004 to 2009. These data were not broken down by pressure zone. February 2, 2012 - DRAFT pw:11 CarollolbocumentslClienUWAlRertonl6595AOOIDeliverableslApperdioaslApp—I 1.3 2006 Buildable Lands Database The City planning department provided a copy of its 2006 Buildable Lands Database spreadsheet in excel format. The information presented in this spreadsheet, however, is applicable to the City of Renton as a whole, not specifically to the RWSA. Furthermore, shapefiles related to the Buildable Lands Database (i.e., vacant land, etc.) were not available in order to be able to break out which parcels should apply to the RWSA by pressure zone. Therefore, the usefulness of the Buildable Lands Database to develop demographic projections by pressure zone was limited. 1.4 City Zoning Map The City's zoning map was provided in GIS format. This map was used in conjunction with the City's list of vacant parcels to determine the vacant land area per pressure zone by zoning designation. 1.5 List of Vacant Parcels The City's water department provided a list of vacant parcels within the RWSA in excel spreadsheet format. This list was transferred into GIS to determine the vacant land area per pressure zone by zoning type, 1.6 Redevelopment Area Environmental Impact Statements The City identified two redevelopment areas for which detailed demographic information has been developed. These are the Regional Urban Center and the Sunset Area Community Planned Action areas. Two environmental impact statements (EISs) were provided with demographic projections for these areas. These are the Boeing Renton EIS and the Sunset Area Community Planned Action EIS_ 2.0 DEMOGRAPHIC PROJECTIONS The demographic projections used in the City's Water System Plan Update are based on Total Population, Total Households, and Total Employment projections per pressure zone. The following steps summarize how the demographic projections were developed: Step 1 - Estimate Infill Capacity: This was accomplished by quantifying the infill potential of each pressure zone and adding it to the existing developed land. For each pressure zone, the total area of vacant land by zoning type was identified based on the list of vacant parcels generated by the City's water division_ The vacant land totals were then converted to numbers of households, population, and employees using the residential and commercial density assumptions (e.g., households per acre). The infill capacity herein defined is therefore existing development plus development of currently vacant lands. Step 2 - Estimate Projections from PSRC: The future number of households, population, and employees was estimated from the PSRC data for each pressure zone. In all pressure zones, the estimated PSRC growth exceeded the infill capacity identified in Step 1 by the February 2, 2012 - DRAFT 2 pw:!/CamllWDocumentslCllenVWAIRentonl8595AOOIDellvera5les/Appendices7App_I year 2040. This indicates that the PSRC projections anticipate all vacant lands be developed, plus additional redevelopment occurs to reach the growth projections by the year 2040. The estimated projections for the year 2070 assume linear growth continues beyond 2040. • Step 3 — Revise Location of Growth: The City anticipates that the growth projected by the PSRC will likely occur in the two identified redevelopment areas. These areas overlap the Highlands 435, Highlands 565, Kennydale 320, and Valley 196 Zones. The net increase in growth from the redevelopment areas was added to these pressure zones (using the highest density redevelopment provided in the EISs). Per City staff, the Regional Urban Center is not expected to be fully built out until the 2070 time frame. Build out of the Sunset Area is assumed to occur by 2030, based on the Sunset Area Community Planned Action EIS. The demographic growth was phased linearly according to these projections_ • Step 4 - Establish the Base Growth Scenario: The base growth scenario assumes a development "cap" that only allows infill and the redevelopment from the Sunset and RUC areas_ To estimate this, the household, employment, and population growth for each pressure zone was limited to the infill capacity plus the redevelopment assumptions. Each pressure zone was allowed to grow until it reached the growth cap for households, population, and employment. The build out year for each pressure zone was assumed to be when the growth projections intersect with the calculated growth "cap." An example of this process is illustrated below. 70 Calculated Growth "Cap" 60 �- (0 PSRC Projection Per Zone -� r v 50 2-40 - --__._._......_......-- a Projected Build Out Year 0 30 t 20 _ Water System Pian Projection 0 = 10 0 2011 2021 2031 2041 2051 2061 2071 Year The attached Tables D-1 through D-6 summarize the projected population, employment, and number of households per pressure zone through 2071. Demographic growth charts per pressure zone are also attached for reference (Figures D-1 through D-16). February 2, 2012 - DRAFT 3 pw:l7Carollo/DocumenislClienVWAIRentor18595A001Deliverahles/AppendiceslApp-I 3.0 ACCOUNT PROJECTIONS The next step in the development of the projected water demands was to transform the projected demographic increases into increases in the number of connections. The population, household, and employment projections were converted into percentage growth rates for each pressure zone relative to the 2010 population, household, and employment values developed by the PSRC_ The future number of connections per pressure zone were determined by multiplying the accounts in 2010 by the derived growth rates per zone. Residential accounts were multiplied by the total household growth rates. Commercial, industrial, and irrigation accounts were multiplied by the employment growth rates. Table A-1 summarizes the projected number of accounts per pressure zone. Account projections per pressure zone are also shown on Figures A-1 through A-16. 4.0 EQUIVALENT RESIDENTIAL UNIT PROJECTIONS Once the number of projected connections were determined per pressure zone, these connections were converted into the number of equivalent residential units (ERUs) by multiplying the projected number of accounts provided by the number of ERUs per account (see Chapter 3 text for more information on how this was calculated). It should be noted that the number of ERUs does not include unaccounted for water, miscellaneous water use, wholesale, and large water user demand. Water demands associated with these elements were considered separately and added on top of the computed water demands by pressure zone. Table E-1 summarizes the projected number of ERUs per pressure zone. Figure E-1 shows the projected number of ERUs in the RWSA through 2071. 5.0 WATER DEMAND PROJECTIONS The projected average day demands (ADD) per pressure zone was determined by multiplying the projected number of ERUs by the demand per ERU (171 gpd/ERU). In addition, unaccounted for water, miscellaneous water use, and wholesale water to project the total average day demand were also added, as described below: Unaccounted-for Water: Unaccounted-for water fluctuated between 15.8 percent and 20.2 percent of the total City production between 2004 and 2009, with an average of 17.8 percent. The demand projections assume that unaccounted-for water will continue to account for roughly 17.8 percent of the total City demand through year 2071. Other Authorized Water Consumption: Other authorized water consumption fluctuated between 0.38 and 0.88 percent of the total City production between 2004 to 2009, with an average of 0.57 percent. The demand projections assume that other authorized water consumption will account for 0.57 percent of total City demand through 2071. However, February 2, 2012 - DRAFT 4 pw:llCarolloODeumentslClienVWAlRemmnl8595AQOlDeliverahieslAppendiceslApp_I tracking of this demand is anticipated to grow as the City improves tracking of other authorized uses. Wholesale Water Consumption to Skyway: Wholesale demands for Skyway are taken from the Skyway Water and Sewer District Comprehensive Plan - Water and Sewer Systems. Forecast demands were only available through 2022. Skyway wholesale water demands from 2031 through 2071 are assumed to be equal to the 2022 demands. Top Water Users: The City has two additional customers that are considered large water users: the Boeing Plant and the King County Wastewater Treatment Plant. For the purposes of the future water demand projections, it was assumed that the King County Wastewater Treatment Plant and the Boeing Plant's water demand would not increase in the future. Based on consumption data provided by the City for these two users, there was a downward trend in water demand from these customers from 2004 to 2009. The projected maximum day demand (MDD) is simply the projected ADD multiplied by the MDD/ADD factor of 1.83 (see Chapter 3 for derivation of this value). The projected MDD for the Skyway Wholesale demand was based on the projections provided from the 2005 Skyway Comprehensive Plan. Tables W-1 and W-2 provides the projected ADD and MDD by customer type per pressure zone. Table W-3 summarizes the ADD and MDD by pressure zone. Figure W-1 provides a visual representation of the projected system -wide ADD and MDD.

The construction of all City water system improvements shall comply with the City Development regulations and standards, the latest City adopted version of Washington State Department of Transportation (WSDOT) Standard Specifications for Road, Bridge, and Municipal Construction as amended by APWA and by the City of Renton Public Works Department. GENERAL REQUIREMENTS FOR EXTENSION OF WATER MAINS Fireflow requirements Fireflow requirements shall be as determined by the City of Renton Fire Marshal. A. The City Water Utility will determine the available fireflow using its computer simulated hydraulic model of the City water system. B. The minimum system pressure during fireflow analysis is 20psi at the fire location and 30 psi throughout the rest of the distribution system. New developments or redevelopment of existing sites are required to meet the minimum City fireflow requirements. The developer shall provide information to the City to determine the fireflow requirements for the development or redevelopment. The developer is responsible for the design and installation of all necessary water main improvements to provide the required Fireflow including off-site and on-site water mains. The change of use of existing buildings or areas may also require the installation of the water main improvements. Water main Sizing The diameter of transmission main(s) shall be determined by hydraulic analysis to verify that the main(s) can deliver the required fire flow demand for a proposed development or redevelopment project. The minimum size distribution system line shall not be less than eight (8) inches in diameter and for a looped system. The minimum size distribution system in single family residential areas shall not be less than eight inches (8") in pipe diameter when the main is serving hydrants and domestic water services. Exception to the minimum diameter might be made in short cul-de-sacs and in areas where looping of a water main is not feasible and when no future extension will be required. In these cases the main stubs could be a minimum of four inches (4") in diameter if no fire hydrants are connected. The sizing of dead-end water main without fire hydrants shall provide sufficient flow to the domestic meters and water services. Water mains in multi -family residential and in non-residential areas shall be sized to provide the required fire flow demand and shall not be less than eight inches (8") in pipe diameter. Water main Oversizing If it is determined that it would be to the best interests of the City and the general locality to be benefited thereby to install a larger size main than one then needed or considered by the owners or developers immediately abutting the street, alley or easement in which such a main is to be placed, then the City may at its own discretion, require the installation of such a larger main in which case the City shall pay the difference in cost between the installation cost of the similar main and of the larger main. Any party required to oversize the water mains may request the City Water Utility participate in the cost of the project. Pipeline Velocities In accordance with DOH recommendations, the City of Renton requires that the design of new distribution mains provide for operating velocities less than or equal to eight feet per second (8 ft/sec) under fire flow conditions and other emergency demand conditions, and under peak hour demand.

Materials and workmanship are required to be in conformance with standards for the Standard Specifications for Road, Bridge, and Municipal Construction prepared by the Washington State Chapter of the American Public Works Association (APWA) and the Washington State Department of Transportation (WSDOT) and shall comply with the most current edition, as modified by the City of Renton Supplemental Specifications. 1 An asphalt paver shall be used in accordance with Section 5-04.3(3) of Standard Specifications. A "Layton Box" or equal may be used in place of the power -propelled paver. Rollers shall be used in accordance with Section 5-04.3(4) of the Standard Specifications. "Plate Compactors" and "Jumping Jacks" SHALL NOT be used in lieu of rollers. 2. Trench backfill and resurfacing shall be as shown in the City of Renton Standard Details, unless modified by the City Permit. Surfacing depths shown in the Standard Details are minimums and may be increased by the Engineer to meet traffic loads or site conditions. SECTION 7 REQUIREMENT FOR PATCHING, OVERLAY, OVERLAY WIDTHS All trench and pavement cuts shall be made by sawcut or by grinding. Sawcuts or grinding shall be a minimum of one foot (1') outside the trench width. The top two inches (7) of asphalt shall be ground down to a minimum distance of one foot (1') beyond the actual outside edges of the trench and shall be replaced with two inches (2") of Class B asphalt, per City of Renton Standards. At the discretion of the engineer, a full street width overlay may be required. Lane -width or a full street -width overlay will be determined based upon the location and length of the proposed trench within the roadway cross-section. Changes in field conditions may warrant implementation of additional overlay requirements. Trenches (Road Crossings): The minimum width of a transverse patch (road crossing) shall be six and one-half feet (6.5'). See City of Renton Standard Plan Drawing #HR —23 (SP Page: H032A). Any affected lane will be ground down two inches (2") and paved for the entire width of the lane. c. Patch shall be a minimum of one foot (1') beyond the excavation and patch length shall be a minimum of an entire traveled lane. If the outside of the trenching is within three feet (3') of any adjacent lane line, the entire adjacent traveled lane affected will be repaved e. An area including the trench and one foot (1') on each side of the trench but not less than six and one half feet (65) total for the entire width of the affected traveled lanes will be ground down to a depth of two inches (2H). A two-inch (2n) overlay of Class B asphalt will be applied per City standards. Trenches Running Parallel With the Street: a. The minimum width of a longitudinal patch shall be four and one-half feet (45). See City of Renton Standard Plan Drawing #HR -05 (SP Page H032). b. If the trenching is within a single traveled lane, an entire lane -width overlay will be required. c. If the outside of the trenching is within three feet (3') of any adjacent lane line, the entire adjacent traveled lane affected will be overlaid. d. If the trenching is greater than, or equal to 30% of lane per block (660 -foot maximum block length), or if the total patches exceed 12 per block, then the lanes affected will be overlaid. Minimum overlay shall include all patches within the block section. e. The entire traveled lane width for the length of the trench and an additional ten feet (10') at each end of the trench will be ground down to a depth of two inches (2"). A two-inch (2") overlay of Class B will be applied per City standards. 3. Potholing: Potholing shall meet the same requirements as trenching and pavement restoration. Potholing shall be a minimum of one foot (1') beyond the excavation. All affected lanes will be ground down to a depth of two inches (2") and paved not less than six and one half feet (6.5') wide for the entire width of the lane. Potholes greater than five feet (5') in length, width or diameter shall be restored to trench restoration standards. In all cases, potholes shall be repaired per Renton Standard Plan # HR05 (SP Page H032). Restoration requirements utilizing vactor equipment will be determined by the engineer. SECTION 8 PAVEMENT REMOVAL IN LIEU OF GRINDING The contractor in all cases can remove the pavement in the replacement area instead of grinding out the specified two inches (2") of asphalt. Full pavement replacement to meet or exceed the existing pavement depth will be required for the area of pavement removal. SECTION 9 TRENCH BACKFILL AND RESTORATION CONSTRUCTION REQUIREMENTS Trench restoration shall be either by a patch or overlay method, as required and indicated on City of Renton Standard Plans #HR -05, HR -23, and HR -22 (SP Pages #H032, H032A, and H033). 2. All trench and pavement cuts, which will not be overlaid, shall be made by sawcut or grinding. Sawcuts shall be a minimum of two feet (2') outside the excavated trench width. 3. All trenching within the top four feet (4') shall be backfilled with crushed surfacing materials conforming to Section 4-04 of the Standard Specifications. Any trenching over four feet (4') in depth may use materials approved by the Engineer or Materials Lab for backfilling below the four -foot (4') depth. If the existing material (or other material) is determined by the Engineer to be suitable for backfill, the contractor may use the native material, except that the top six inches (6") shall be crushed surfacing top course material. The trench shall be compacted to a minimum ninety-five percent (95%) density, as described in Section 2-03 of the Standard Specifications. In the top six feet (6) of any trench, backfill compaction shall be performed in eight to 12 -inch (8-12") lifts. Any trench deeper than six feet (6) may be compacted in 24 -inch lifts, up to the top six-foot (6) zone. All compaction shall be performed by mechanical methods. The compaction tests may be performed in maximum four -foot (4') vertical increments. The test results shall be given to the Engineer for review and approval prior to paving. The number and location of tests required shall be determined by the Engineer. Temporary restoration of trenches for overnight use shall be accomplished by using MC mix (cold mix), Asphalt Treated Base (ATB), or steel plates, as approved by the Engineer_ ATB used for temporary restoration may be dumped directly into the trench, bladed out and rolled. After rolling, the trench must be filled flush with asphalt to provide a smooth riding surface. If the temporary restoration does not hold up, the Contractor shall repair the patch within eight hours of being notified of the problem by the City. This requirement applies 24 hours per day, seven days a week. In the event that the City determines to repair the temporary patch, the contractor shall reimburse the City in an amount that is double the City's cost in repairing the patch, with the second half of the reimbursement to represent City overhead and hidden costs. Asphalt Concrete Class E or Class B shall be placed to the compacted depth as required and indicated on City of Renton Standard Plans #HR -05, HR -23, and HR -22 (SP Pages #H032, H032A, and H033) or as directed by the Engineer. The grade of asphalt shall be AR -4000W. The materials shall be made in conformance with Section 9- 02,1(4) of the Standard Specifications. Tack coat shall be applied to the existing pavement at edge of saw cuts and shall be emulsified asphalt grade CSS - 1, as specified in Section 9-02.1(6) of the Standard Specifications. Tack shall be applied as specified in Section 5- 04 of the Standard Specifications. Asphalt Concrete Class E or Class B, shall be placed in accordance with Section 5-04 of the Standard Specifications; except those longitudinal joints between successive layers of asphalt concrete shall be displaced laterally a minimum of twelve inches (12"), unless otherwise approved by the Engineer. Fine and coarse aggregate shall be in accordance with Section 9-03.8 of the Standard Specifications. All street surfaces, walks or driveways within the street trenching areas shall be feathered and shimmed to an extent that provides a smooth -riding connection and expeditious drainage flow for the newly paved surface. Feathering and shimming shall not decrease the minimum vertical curb depth below four inches (4") for storm water flow. The Engineer may require additional grinding to increase the curb depth available for storm water flow in areas that are inadequate. Shimming and feathering, as required by the Engineer, shall be accomplished by raking out the oversized aggregates from the Class B mix as appropriate. Surface smoothness shall be per Section 5-04.3(13) of the Standard Specifications. The paving shall be corrected by removal and repaving of the trench only. Asphalt patch depths will vary based upon the streets being trenched. The actual depths of asphalt and the work to be performed shall be as required and indicated on City of Renton Standard Plans #HR -05, HR -23, and HR -22 (SP Pages #H032, H032A, and H033). Compaction of all lifts of asphalt shall be a minimum ninety-two percent (92%) of density as determined by WSDOT Test Method 705. The number of tests required shall be determined by the Engineer. Testing shall be performed by an independent testing lab with the results being supplied to the Engineer. Testing is not intended to relieve the contractor from any liability for the trench restoration. It is intended to show the inspector, and the City, that the restoration meets these specifications. All joints shall be sealed using paving asphalt AR4000W. When trenching within the unpaved roadway shoulder(s), the shoulder shall be restored to its original condition, or bette r. 10. The final patch or overlay shall be completed as soon as possible and shall not exceed fifteen (15) working days after first opening the trench. This time frame may be adjusted if delays are due to inclement paving weather or other adverse conditions that may exist. However, delaying of final patch or overlay work is subject to the Engineer's approval. The Engineer may deem it necessary to complete the work within the fifteen (15) working day time frame and not allow any time extension. Should this occur, the Contractor shall perform the necessary work, as directed by the Engineer. 11. A City of Renton temporary Traffic Control Plan (from Renton Transportation Engineering) shall be submitted and approved by the Engineer a minimum of three (3) working days prior to commencement of work. SECTION 10 REMOVAL OF UTILITY LOCATE MARKINGS FROM SIDEWALKS REQUIRED The Permittee will be required to remove utility locate marks on sidewalks only within the Downtown Core Area.

The existing hydraulic model uses the InfoWater modeling software platform, developed by Innovyze (formerly MWH Soft). This section summarizes the procedures used to update the existing hydraulic model per the Water System Plan Update Scope of Services. iAt1�0.MI+ - ta�'ori .r Water demands in the City's existing hydraulic model were geocoded by the City based on customer billing records for the year 2010. As part of the model update process, these demands were reviewed by pressure zone to verify the demand estimates provided in Chapter 3 of the Water System Plan Update. The 2010 water demands in the City's existing water model were allocated based on the City's total annual water consumption. The demands were then scaled to match the total demand (including unaccounted for water) for both the summer (maximum day demand) and winter (average day demand) scenarios. Existing average and maximum day demands per pressure zone and per operational area are discussed in Chapter 3 of the Water System Plan Update. 2.2 Operational Area Diurnal Patterns Custom diurnal patterns for both winter and summer demands were developed for each of the City's five operational areas_ The custom diurnal patterns are based on SCADA data provided by the City for winter and summer periods in 2009, and normalized so that the average of the hourly multipliers is equal to one_ The diurnal patterns are then multiplied by the 24-hour average demands input at the model nodes for the planning scenario to simulate the normal daily demand variations that occur during a typical winter or summer demand condition. This provides operating data on how the tanks and pumps move water through the system. The diurnal patterns were developed by performing a mass balance between production (i.e., well and other source flows), storage tank inflow or outflow, and booster pump station flows in each operational area. Because SCADA data was not provided for the City's pressure reducing valves (PRVs), it was assumed that these facilities were not operating during the time period for which the diurnal patterns were developed. CAROLLO ENGINEERS 1 February 14, 2012 pa liCarotlolDocumentslgienttiWAtiRenton18595ADO1DeliveraHesLAppendiceslApp_K.docx 0fY of RENTON HYDRAULIC MODEL As shown on Figure 1, the system -wide winter diurnal shows minimal demands during the early morning hours with more significant peaking occurring from the hours of 6:00 a.m. to 2:00 p.m. The maximum hourly peaking factor for the system -wide winter diurnal is 1.47, which occurs during the 12:00 p.m. hour. The system -wide summer diurnal pattern is characterized by a more consistent water demand throughout the day, with a maximum peaking factor of 1.34, which occurs during the 8:00 p.m. hour. A typical diurnal pattern is usually characterized by having two peaks, one occurring in the morning around the 6:00 a.m. to 8:00 a.m. hours, and the other occurring at night around the 6:00 p.m. to 7:00 p.m. hour.

One way to test the accuracy of the hydraulic model is to create a set of known conditions in the water system and then compare the results observed in the field against the results of the hydraulic model simulation using the same conditions. Flow tests conducted in the field on the water system are a standard method to verify the models accuracy and confirm the accuracy of the data used in the hydraulic model construction. Analysis of the flow test data also provides a greater understanding of how the water system operates. Field testing can indicate errors in the data used to develop the hydraulic model, or show that a condition might exist in the field not otherwise known. For example, valves, which are reported as being open, might actually be closed (or vice versa), an obstruction could exist in a pipeline, or pressure settings for a PRV may be slightly different than noted. Field testing can also correct erroneous model data such as incorrect pipe diameters or connections. Data obtained from the field tests can be used to determine appropriate roughness coefficients for mains, as roughness coefficients can vary with age and pipe material.

Carollo ran the model under existing demand conditions in order verify that the model forecasted pressures are reasonable and to make sure that the reservoirs were replenishing following peak hour demands. The macro calibration process included executing the following steps to ensure that the model produces reasonable results. Transmission Main Connectivity. Carollo used the connectivity features of the hydraulic modeling software to verify the connectivity of the transmission and distribution mains within the distribution system. Proper connectivity verifies that there are no interruptions in the pipe connections. Possible issues found using the connectivity locators are reviewed on a case-by-case basis to determine whether adjustments needed to be made to the connectivity of the model_ The model output reports on headloss (ft/kft) and velocity (ftls) were also used to locate possible connectivity issues that required adjustment. System Pressures. The macro calibration compared the model output to typical pressures of each pressure zone. This process allowed Carollo to verify that model facility size (pipe diameters and pump capacity), ground elevations, connectivity, and operational controls were reasonable. Facility Characteristics. Hydraulic model results for the City's wells, booster pump stations, and tanks were reviewed and compared to the City's available SCADA data to verify that data input into the hydraulic model (e.g., pump curves, operational controls, PRV settings, etc.) produced results comparable to what the system experiences. 3.1.2 Fire Flow Test Calibration The second step in model calibration after macro calibration is to compare model results to field pressures measured during a series of fire flow tests. This process is used to develop a calibrated hydraulic model by closely matching model simulated pressures to field pressures under similar demand and system boundary conditions. The model parameters that are adjusted during this process are primarily the pipeline roughness coefficients, although other parameters can also be adjusted as calibration results are generated. Hazen -Williams roughness coefficients, or C -factors, have industry accepted value ranges based on pipeline material, diameter, and age. Characteristics specific to the City's water distribution system such as water quality, temperature, construction methodologies, material suppliers, and other factors may result in roughness coefficients that differ from the average of the industry accepted ranges. Fire flow calibration refines the value of roughness coefficients that best indicate the conditions of the City's distribution system. CAROL LO ENGINEERS 3 February 14, 2012 pw:11Cara1la1DoCuments/ pw.ACarolloDxumenWCAientlWAtiRentonM95A001DeliverablesAppendiceslApp_K docs C3TY oFRENToN HrnRauuc MODEL During average day flows, roughness coefficients have a relatively small effect on the operation of the distribution system. However, as the flows increase in the system on higher demand days or during fire flows, velocity within pipelines increase and roughness coefficients contribute more to overall system headloss. Fire flow tests artificially create high demand events to generate more headloss, allowing a better estimation of the pipeline roughness coefficients. Fire flow tests stress the distribution system by creating a differential between the hydraulic grade line (HGL) at the point of hydrant flow and the system HGL at neighboring hydrants. This HGL differential increases the effect of the roughness coefficients on system losses and allows adjustments to the model to match model pressures to field pressures within an acceptable tolerance. As the model is adjusted to match system pressures, roughness coefficients should be adjusted only within a tolerance of industry accepted roughness coefficient ranges. If a model is unable to match the calibration results without leaving the acceptable range of roughness coefficient values for a given pipeline material and age, there may be cause for further investigation of a previously unknown field condition. Examples of such conditions, which typically arise during hydraulic model calibration, include closed valves, partially closed or malfunctioning valves, extreme corrosion within pipelines, connectivity and diameter errors, and diurnal patterns of large water users. The City performed hydrant flow tests as part of this project so that the most current data available could be utilized to update the model. Nineteen sites were selected within the City's service area. The sites were selected so that each of the City's pressure zones had at least one fire flow test and so that the locations were not near pump stations, valves, or storage facilities, if possible. In general, the test sites are consistent with fire test sites used in the previous Water System Plan, although some sites were relocated. As part of the previous Water System Plan, the City did not conduct Fire Test 8. For this reason, Fire Test 8 was not conducted as part of this Water System Plan Update. The fire flow test locations are shown on Figure 2. The fire flow test data is included in Table 1. Each fire test was conducted by first measuring static pressures at two "pressure" hydrants. Next, two "flowing" hydrants were opened to release a large amount of flow and to cause a significant headloss and pressure drop. With the flowing hydrants open, measurements were recorded to quantify the flow rate from each hydrant, and to determine the residual pressure of the two pressure hydrants. The City also provided SCADA data for the majority of major system facilities, including supply sources (i.e., wells, Springbrook Springs), tanks, and booster pump stations. SCADA data were not available for the City's PRVs. CAROLLO ENGINEERS 4 February 14, 2012 pw:/1Caro11o1DocumenW pw:lfCarolWDocumenWCAientlWAlRentan185B5ADOTeliveraMes4AppendicestiApp_Kdocx � 5E.

The first scenario was called the "static" run, which simulated the water system just prior to each test. The second scenario, referred to as the "residual" run, simulated the system during the test while the hydrants were flowing. A total of 19 tests were performed on the system and therefore a total of 38 computer simulations were created to calibrate the model. According to City staff, the West Hill Reservoir and the West Hill Booster Pump Station were out of service for all of the fire flow tests, except for tests 5, 10, and 15. For test 5, 10, and 15, the West Hill Reservoir and West Hill Booster Pump Station were back in service, but the Hazen Reservoir was out of YaILIVArK--m In both static and residual model scenarios, model demands were scaled up or down to represent the model demand during the fire flow test as reasonably as possible. Based on SCADA data provided by the City, the system -wide daily demand for March 2011 is estimated to have been roughly 4,000 gpm_ These demands were then adjusted to account for the time of day using the operational area diurnal pattern multipliers presented in Section 2.2. Tank levels were also adjusted in each fire test scenario to match the actual tank levels recorded during the tests. In addition, the initial status of the City's wells and booster pumps were modified so that they matched actual conditions (i.e., open or closed) recorded during the tests. The residual model scenarios are identical to the appropriate static model scenarios, except that fire flow demands were added to the appropriate nodes. 3.2 Model Calibration Results Numerous simulations were performed during the calibration phase. For several test locations, the hydrant tests were re -run to check system changes and verify test results. Adjustments were made to the model between runs to minimize the differences between the model and field results. A detailed summary of the calibration results is shown in Table 1. The table lists the results of each field test conducted and corresponding hydraulic model results. For the pressure hydrants, the results are considered acceptable if the model simulated pressures are within 10 psi or have a 10 percent difference to the field data. Model pressures within 5 psi or 5 percent of the field measurements are considered very good. As shown in Table 2, all of the model simulations resulted in pressure differences within 10 psi or 10 percent of the field measured pressures. For many of these tests, the model -simulated pressures as compared to the field -measured pressures are within 5% or the very good range. 4.0 SUMMARY For all of the fire flow tests performed by City staff, the model -simulated pressures as compared to the field -measured pressures are in the good or very good range. The model is calibrated for the system as it is configured and operated in 2011. Therefore, the model is an appropriate tool for projecting future conditions.

F-2 F-2 Appendix L WELLHEAD PROTECTION PLAN EXECUTIVE SUMMARY Wellhead protection is a means by which a community can actively and efficiently protect its drinking water resources. Wellhead protection is preventative in nature, rather than reactive and aims at preventing contaminants from entering the area of land around water supply wells. The wellhead protection area includes: "the surface orsubsurface area surrounding a water well or wellfield supplying a public water system, through which contaminants ore reasonably likely to move toward and reach such well or wellfield" (US EPA. 1987). The City of Renton aquifer protection efforts began as a recommendation in its 1983 Water System Plan. A Well Field Monitoring Study delineating Aquifer Protection Areas/ capture zones (APA) was completed by CH2M Hill in 1988. The capture zones were updated for the 2006 Water System Plan using the Renton Groundwater Model (Modflow) in conjunction with the PATH31D particle tracking program for the downtown and Maplewood wells. Capture zones for well 5a were delineated with the fixed radius method, and capture zones for Springbrook Springs were delineated based on groundwater flow patterns and overlying surface water catchment. A overview of modeling methods utilized are presented here and a more in depth discussion of all these modeling efforts are presented in Appendix Q of the February 2006 Renton Water System Plan. The updated capture zones, Figures 2-, 5, 6, 7, will become the new Aquifer Protection Area zones. Potential contaminant sources within wellhead protection area. The inventory of potential contamination sources within the WHPA is being updated as part of Monitoring Wells Prioritization & Repair, 2011 contract. This study will conduct a risk assessment on the downtown aquifer, prioritize monitoring wells based on existing and potential contaminant source risk assessment, as well as repair and secure monitoring wells. This study will be attached to this chapter as an update upon its completion. Businesses in the redefined capture zones will be notified. The APA zones 1, 2 and 1a will also be redefined. The requirements of the Aquifer Protection Area found in the Renton Municipal Code (see Table 1-1) will be applied to businesses that meet the zone -defined criteria. Public aquifer awareness activities will continue through outreach to schools, festivals, employee training and yard care workshops. Compliance with State Wellhead Protection Requirements Executive Summary 2012-revised.doo The City complies with Wellhead Protection requirements for Group A Public Water Systems contained in Chapter 246-290-135(3) WAC and administered by the Washington Department of Health. Compliance is documented in chapters 3, 4, and 5 of this report and section 5.7. These chapters address delineation of capture zones, identification of potential sources of contamination, notification of owners and regulators of potential contamination sources, and verification that the City could continue to supply customers in the event of loss due to contamination of its primary source of water. Section 5.7 addresses coordination with emergency responders. Executive Summary 2012-revised.docl 1. INTRODUCTION 1.1 Wellhead Protection Requirements The purpose of this report is to document compliance with Wellhead Protection requirements for Group A Public Water Systems contained in Chapter 246-290-135(3) WAC and administered by the Washington Department of Health (DOH). A wellhead protection area is defined by DOH as the surface and subsurface around a well or well field contaminants are likely to pass through to reach a drinking water source. The goal of the Wellhead Protection Plan is to prevent the contamination of groundwater sources through planning and the management of existing and potential contaminant sources. The key components of a wellhead protection program are: Delineation (or definition) of wellhead protection areas. • Inventory of potential contaminant sources within wellhead protection area. • Management of wellhead protection areas to prevent contamination. 1.2 Implementation of Renton's Wellhead Protection Compliance with these requirements is part of a broader Renton city effort referred to as the "Aquifer Protection Program". This report describes how the City complies with the DOH requirements in the context of this broader program. The City of Renton began its efforts to protect its ground water supplies with a recommendation for an Aquifer Protection Program in its 1953 Water System Plan. An overturned tanker truck carrying diesel fuel near city wells motivated the City to undertake a Well Field Protection Study and acquire Maplewood Golf Course as a location for an alternate supply. By 1986, the City had established a network of groundwater monitoring wells and petitioned and was granted by the EPA Sole Source Aquifer status and protection. This designation helps to protect the aquifer by making sure that "no commitment for federal financial assistance (through a grant, contract, loan guarantee, or otherwise) may be entered into for any project which the Administrator determines may contaminate such aquifer through a recharge zone so as to create a significant hazard to public health, but a commitment for federal assistance may, if authorized under another provision of law, be entered into a plan or design the project to assure that it will not so contaminate the aquifer." Designation of the Aquifer Protection Area ( combined "1 -year Capture Zone", "5 -year Capture Zone", and "10 -year Capture Zone" areas within the City limits) by the Renton City Council came in 1988. Shortly thereafter, an aquifer awareness program was initiated with a Centennial Clean Water Fund Grant. An Aquifer Protection Ordinance passed by the City Council in 1992, placed restrictions on the storage and handling of hazardous materials in the Aquifer Protection Area. The Aquifer Awareness Program continues today and Renton has been designated as a Groundwater Guardian Community by the Groundwater Foundation. The 2012 plan begins the task to align the 1, 5, and 10 -year capture zones that were developed for the 2006 Water System Plan with the Aquifer Protection Area. The new capture zones were delineated using the Renton Groundwater Model (Modflow) in conjunction with the PATH31D particle tracking program for the downtown and Maplewood wells. Capture zones for well 5a were delineated with the fixed radius method, and capture zones for Springbrook Springs were delineated based on groundwater flow patterns and overlying surface water catchment. The updated capture zones can be seen in Figures 2-3, 5, 6, 7. The businesses in these zones will be notified that they are in the Aquifer Protection Area. The City's Aquifer Protection Ordinance will be applied to these new areas as well as any overlap with old APA zones. The Water Utility samples a network of monitoring wells to provide an early warning of contaminants present in production well capture zones. This enables the City to optimize use of production wells to avoid drawing contamination, if present in the aquifer, into the drinking water distribution system. The monitoring plan is currently being reviewed and updated to evaluate contamination sources and prioritize risks as well as rejuvenation of the wells. 1-2 ADD ANY UPDATES Table 1-1: Chronology of the Development of Renton's Aquifer Protection Program 1983 to 2010 ACTION OR EVENT YEAR Water System Plan recommends Aquifer Protection Program 1983 Tanker truck carrying diesel fuel overturns on 1-405 and spills its contents 1983 City Council authorizes Well Field Protection Study 1983 Well Field Protection Study completed by CH2M Hill and recommendations adopted by City Council 1984 Maplewood Golf Course acquired for use as future well field to provide back up for downtown aquifer 1985 Development of Maplewood supply 1986-1999 Well Field Monitoring Study completed by CH2M Hill; Includes installation of monitoring wells, provides ground water quality and flow information for the downtown aquifer, estimates interaction with the Cedar River, and 1986-1988 delineates the Aquifer Protection Area; Initiates ongoing early -detection water quality and water level monitoring program Initiation of ground water quality monitoring using a network of monitoring wells 1986 (ongoing) Olympic Pipe Line Company petroleum spill in Maple Valley; City monitors progress of cleanup to ensure no 1986-1993 contamination of downtown wells.

Tetrachloroethane (PCE) is detected in well PW -8 during routine sampling. PCE is later detected in wells, RW -1, RW -2 & RW -3, and PW -9 as well as in groundwater monitoring wells MW -18, MW -19, MW -20, MW -24, MW -31S, MW -40 and MW -42. The contamination is traced to wastewater ponds and waste soil mixing areas located on the Stoneway property next to Cedar River Park. July and August 1998, Stoneway removes waste concrete slurry from 1997 four ponds found to contain PCE contamination. In addition Stoneway removes waste soil stored on site in the waste soil mixing area which was also found to be contaminated with PCE. Sampling revels the levels of PCE contamination begin to drop in City wells.

PROTECTION AREA DELINEATIONS by SOURCE The City of Renton draws its water from four distinct sources. These are described below and their locations are shown on Figure 2-1. 2.1 Cedar Valley Aquifer The primary source of the Renton municipal water supply is the Cedar Valley Aquifer, designated a Sole Source by the EPA in 1988. The aquifer boundaries correspond to the areal extent of the post-Vashon alluvium of the lower Cedar River Valley. Aquifer materials occur almost continuously between Renton and Cedar Falls (Figure 2-2). This shallow aquifer is physically susceptible to contamination since there is no confining layer between the land surface and the water table to retard the downward migration of hazardous chemical spills or other releases of contaminants. In the downtown Renton area especially, it is also vulnerable to degradation due to the presence of numerous potential sources of contamination. In the vicinity of the wellfield constructed in downtown Renton, the aquifer consists of coarse-grained sediments deposited at the mouth of the prehistoric Cedar River during the last glacial period. The water table is approximately 23 feet from the surface and the aquifer has an average thickness of 70 feet. Soils overlying the aquifer are silt, sand, and gravel while the aquifer itself is comprised of coarser, very permeable sandy gravel. Aquifer transmissivity is estimated to range from about 1 to 2.3 million gallons/day-foot (gpd/ft). Assuming transmissivity of 1.3 million gpd/ft, hydraulic conductivity is on the order of 2,500 ft/day. Recharge is local, both from direct precipitation and subflow. The Department of Health contamination susceptibility rating of wells located in the Cedar Valley Aquifer is "moderate to high". The City operates six production wells in the Cedar Valley Aquifer. Wells RW1, RW2, and RW3 each have a pumping capacity of 2,200 gpm and are screened at depths ranging from 50 to 105 feet. Well EW3 may be used in an emergency, its capacity is 1600 gpm and it is screened from 40 to 70 feet below ground surface. Wells PWS and PW9 have pumping capacities of 3,500 and 1,200 gpm, respectively. The wells are screened at depths ranging from 50 to 105 feet. 2.1.1 Cedar Valley Aquifer WHPA Delineation The Renton Groundwater Model was developed to simulate the groundwater flow system in the Renton vicinity in three dimensions. The model was constructed using Modflow, the US Geological Survey finite difference computer code (McDonald & Harbaugh, 1958). The model simulates areal recharge, concentrated recharge along the edges of uplands, groundwater interactions with the Cedar River and Lake Washington, springflow along the North Uplands (including Maplewood Creek baseflow), pumping withdrawals, and subflow across model boundaries. Capture zones were delineated using the Renton Groundwater Model in conjunction with the PATH3D particle tracking program. Figure 2-3 shows the areal extent of the 1-, 5-, and 10 -year capture zones associated with pumping the downtown wellfield. In extent, they are largely 2-I limited to the lowland surficial aquifers (deltaic and Cedar Valley alluvial aquifers). The 1 -year capture zone occurs exclusively in the lowland aquifers, whereas portions of the 5- and 10 -year capture zones extend beneath the southwest corner of the North Uplands. In addition, a portion of the 10 -year capture zone in the deltaic aquifer extends beyond the model boundary. Near the southwest corner of the model domain (near the old Black River channel) the 5 -year capture zone approaches the model boundary and the 10 -year capture zone occurs outside of the model domain. Where the 10 -year capture zone lies outside of the model domain, the 5 - year travel time was used to extend the boundary. Extension of the 10 -year capture zone also considered geologic constraints (bedrock occurrence) in the old Black River channel to estimate groundwater flow directions. The 10 -year capture zone outside the model domain is dashed to indicate the uncertainty associated with this poorly characterized area outside of the model domain. Capture zones delineated for groundwater flow beneath the North Uplands are representative of average groundwater velocities in these areas. A nose -shaped projection of the 5- and 10 -year capture zones delineated along the western edge of the North Uplands is dashed to convey uncertainty. This boundary is based on indirect evidence suggesting concentrated groundwater flow in this vicinity. 2.2 Springbrook Springs About fifteen percent of the City's current water supply comes from Springbrook Springs located at the extreme southern city limits. A water -bearing sand and gravel layer enclosed in a thick sequence of glacial till intercepts the surface on the hillside at Springbrook Springs. Two infiltration galleries collect and channel from 300 to 500 gpm into the transmission pipeline. The Springs have not been extensively studied. The recharge area has been estimated by combining the surface area draining to the Springs with the estimated groundwater recharge area. The latter is based on well driller reports for wells in the vicinity of the Springs. The Department of Health contamination susceptibility rating of the Springs is "moderate to high", although the delayed response of discharge to seasonal precipitation suggests that, due to overlying till, the Springs may be of low susceptibility. 2.2.1 Springbrook Springs WHPA Delineation Springbrook Springs emits from undifferentiated Vashon glacial sediments (Hart Crowser, 1975). The springs are located on the west side of the Renton South uplands (Figure 2-4), at an elevation of approximately 200 feet above mean sea level (NAV 1929). The dashed green line on Figure 2-5 showing the delineated surface water area that contributes to the springs, was based on topography. The groundwater area of contribution was delineated by calculations based on hydrogeologic mapping. Figure 2-5 also shows the recommended WHPA travel time zones. The 1 -year travel time zone includes those portions of the overall area of contribution within 3,100 feet of the spring, plus the entire surface water catchment. The 5 -year time of travel zone occupies areas between the 1 -year travel time zone and a distance of 9,200 feet from the spring. The 10 -year time of travel WHPA was identified as areas extending beyond the 5- year zone which likely contribute groundwater to 2-2 the springs. The 10 -year zone was extended upgradient to a groundwater divide identified by the USGS (1995) near Lake Youngs. 2.3 The Maplewood Production Aquifer The Maplewood production aquifer is located east of the downtown area under the Maplewood Golf Course. It serves as a redundant source of supply for the vulnerable downtown aquifer. The Maplewood aquifer is believed to extend northward into hydrostratigraphically-correlated zones beneath the North Uplands. It ranges from 70 to 120 feet thick and is encountered from approximately 135 to 345 feet below the golf course. The Maplewood aquifer is confined with evidence of some leakage. Gradients are predominantly upward. Estimated transmissivities range from 49,000 to 76,000 gpd/ft with corresponding hydraulic conductivity ranging from 94 to 128 ft/day. Recharge is believed to occur predominantly from the North Uplands while discharge occurs in the Cedar Valley via upward flow to the alluvial aquifer east of the bedrock narrows shown on Figure 2-2. Other recharge and discharge points may exist. The Department of Health contamination susceptibility rating of the Maplewood aquifer is "low". Production wells completed in the Maplewood aquifer,PW11, 12, and 17, have pumping capacities of 2,500, 1,500, and 1,500 gpm, respectively. These wells are screened at depths ranging from 284 to 344 feet below ground. 2.3.1 Maplewood WHPA Delineation Capture zones for the Maplewood wellfield were delineated using the same Renton Groundwater Model in conjunction with the PATH31) particle tracking program that was also used to delineate the Cedar Valley Aquifer WHPA. The capture are shown on Figure 2-6. The 1 -year capture zone is largely limited to the Cedar River Valley, whereas the 5- and 10 -year capture zones extend beneath the North and South Uplands. The southeast portions of the 5- and 10 -year capture zones extend beyond the model boundary. Hydrogeologic conditions in this area have not been well defined, and simplifying assumptions were required to approximate the capture zones outside of the model domain. Capture zones delineated for groundwater flow beneath the North Uplands are representative of average groundwater velocities in these areas. Because modeled aquifer properties for the sediment -filled bedrock valley beneath the South Uplands are unknown, reasonable estimated values were employed. In a similar fashion to the North Uplands, assumptions of uniformity within model layers provide model estimates of average groundwater velocities in these South Uplands sediments. 2.4 Well 5A Well 5A is located near the northern city limits east of Lake Washington. This well has a pumping capacity of 1500 gpm and is completed in a sand and gravel aquifer zone approximately 280 to 390 2-3 feet below ground (about -42 to -152 feet mean sea level). The aquifer zone is overlain by stratified glacial deposits of fine to coarse sand and gravel layered with silt and clay. The recharge area for Well 5A is not known but there are some indications that the well may be withdrawing from the Maplewood production aquifer which is believed to extend northeasterly from the Maplewood area. The Department of Health contamination susceptibility rating of Well 5A is "low". 2.3.1 Well 5A WHPA Delineation Because little hydrogeologic characterization has been performed in the Well 5a area and groundwater flow patterns have not been characterized, the calculated fixed radius (CFR) method was used to delineate the time travel boundaries (Figure 2-7). Well pumping rate, estimated porosity of the aquifer, and open or screened interval of the well used for the CFR were assumed to be same as t he Maplewood aquifer. 2-4 FIGURE 2-1.

CONTAMINANT SOURCE INVENTORY, RISK ASSESSMENT AND NOTIFICATION OF OWNERS AND AGENCIES An essential element of the wellhead protection is an inventory of all potential groundwater contaminant sources in and around delineated wellhead protection areas. The purpose of the inventory is to identify past, present and proposed activities that may pose a threat to the aquifer. This section presents an inventory and assessment of risks to the City of Renton's groundwater sources. The potential contaminant source inventory and assessment were conducted using techniques consistent with current Department of Health guidance documents. 3.1 COMPILATION OF POINT SOURCE INFORMATION Potential point sources of groundwater contamination located within the 10 -year capture zones of the City of Renton water supply wells were identified using the following sources of information: Department of Ecology Confirmed and Suspected Contaminated Sites Report This list contains information about sites that are undergoing cleanup and .sites that are awaiting investigation and/or cleanup. Department of Ecology Underground Storage Tanks and Leaking Underground Storage Tanks - Lists and Information Washington State currently regulates active tanks including gas stations, industries, commercial properties, and governmental entities. While the UST data file contains information on both operational and closed USTs, we report only the active tanks. Department of Ecology Hazardous Waste Generators Database Ecology provided us with a listing of hazardous waste generators regulated under the federal and state regulations. City of Renton Aquifer Protection Area Facilities Database The City of Renton has identified businesses and other entities within the Aquifer Protection Area that store more than 20 gallons of hazardous material. These sites are referred to as "facilities storing hazardous materials" in this report. 3.2 POINT SOURCES OF CONTAMINATION Point sources include USTs, LUSTS, Facilities Storing Hazardous Materials, Confirmed and Suspected Contaminated Sites, Resource Conservation and Recovery Act (RCRA) sites, solid waste facilities and cemeteries. 3-1 Table 3-1 presents a list of Facilities Storing Hazardous Materials that are located within the City of Renton capture zones. 3.2.1 Facilities Storing Hazardous Materials The Water Utility regulates facilities located in the Aquifer Protection Area that handle and store hazardous materials. The purpose of this program is to ensure that hazardous materials are handled in a manner that prevents their release to the environment where they may contaminate the aquifer. 3.2.2 Underground Storage Tanks USTs identified for this project are those regulated by Ecology. The Department of Ecology regulates USTs in accordance with WAC 173-360. Tanks excluded from this list are: home heating oil tanks, tanks closed before 1990, tanks smaller than 100 gallons, process system tanks, wastewater tanks, vaults, lagoons, sumps, natural gas tanks, home or farms (noncommercial) motor fuel tanks, septic tanks, and tanks inside buildings. USTs in the Ecology database include new, old, closed, and operational USTs, typically located at gas stations, maintenance facilities, the airport, and truck fleet facilities. The purpose of the UST management program is to reduce groundwater contamination, which has been historically common from this source category. The regulation required tank upgrades, leak detection devices, and liability insurance as of December 1998. USTs typically contain hydrocarbon fuels and waste oils that may contaminate groundwater. If leaked, the fuels may either migrate as a separate phase or dissolved in groundwater. It is unlikely that free petroleum product would enter a well. Fuel constituents most likely to dissolve out of fuel into water at concentrations problematic for drinking water are light aromatic hydrocarbons (benzene, toluene, xylene, and ethylbenzene) and total petroleum hydrocarbons (TPH). The aromatic constituents comprise typically less than 30% of the total fuel mass. These components, when they are dissolved in groundwater, have the following subsurface migration characteristics: They move in the same direction as groundwater They move marginally slower than groundwater They are consumed over time by microbes in the ground (they biodegrade) 3.2.3 Leaking Underground Storage Tanks LUSTs are USTs with reported releases of petroleum fuels to the ground under WAC 173-360 (Underground Storage Tank Regulations). Sites with large releases of petroleum fuel but no UST may also be included. The UST section above describes the character of petroleum fuel migration and risks in the subsurface. Ecology relies heavily on voluntary "Independent Remedial Actions" for LUST remediation. Independent remedial actions are designed to allow owners of contaminated properties to quickly and economically remediate sites. They are therefore commonly performed by owners of LUSTs using written Ecology guidance, but with little Ecology input during the cleanup process. 3-2 Independent remedial action reports are required to be submitted to Ecology after completion of work. 3-3 3.2.4 Home Heating Oil Tanks The City of Renton conducted a Home Heating Oil Tank Study and concluded that home heating oil tanks constitute a risk to the water supply (SCS Engineers, 1994). The total number and distribution of tanks were estimated using information based upon the King County Assessor's parcel database indicating home heating type. Tanks in this database likely include those currently in use as well as those that are unused. Figure 3-1 presents heating oil tank density in the City of Renton. The risk posed by home heating oil tanks is migration of petroleum fuel constituents to wells with moving groundwater, as discussed under the UST category. Areas with the highest tank density are in the one-year, five-year, and ten-year capture zones of the Downtown wells and in the five-year and ten-year capture zones of well 5A. Most of the tanks in the APA are 30 to 44 years old. Compared to gasoline and diesel, heating oil contains relatively low concentrations of the toxic and mobile petroleum fuel components described above under USTs, which may account for the fact that the City has not experienced a documented contamination of wells due to heating oil tanks. However, the large number of heating oil tanks and their ages contributed to the identification of risk by the City in the 1994 study. 3.2.5 Confirmed and Suspected Contaminated Sites The purpose of the Washington State Toxics Cleanup Program is to clean up sites with contaminated soil or water in accordance with the Model Toxics Control Act (WAC 173-330) and an extensive body of related guidance. Sites on the Confirmed and Suspected Contaminated Sites List are those with non -petroleum contaminants, or sites with petroleum and non -petroleum contaminants, in soil or water. LUSTS and other sites are not included if only petroleum chemicals are present, unless the contamination volume is unusually large. The risk posed by these sites is migration of contaminants to wells (or other receptors). Because contamination at these sites has been identified and registered with Ecology, migration is usually monitored and damage to wells can be averted. Nonetheless, these sites, along with LUSTs, represent the locations of registered releases of hazardous chemicals to the ground in the well capture zones. 3.2.6 Hazardous Waste Generators Federal and state rules promulgated under the authority of the Resource Conservation and Recovery Act (RCRA) regulate facilities generating, transporting, treating, storing, and disposing of hazardous wastes or extremely hazardous wastes. The rules establish a system to track hazardous wastes from generation to disposal. Hazardous wastes are those wastes defined in WAC 173-303 (Dangerous Waste Regulations) as threats to human health or the environment. The risk posed by hazardous waste generators is the illegal disposal or spillage of waste within the well capture zones. Ecology's Hazardous Waste and Toxics Reduction Program perform management and permitting of these sites. The Local Hazardous Waste Management Program in King County implements a program to ensure that hazardous waste from small quantity generators does not end up in sanitary sewers and landfills. King County and the cities in King County jointly implement this program. A small quantity generator is a facility generating less than 220 pounds of hazardous waste, or 2.2 pounds of extremely hazardous waste, per month. Table 3-1 lists large and medium 3-4 quantity hazardous waste generators but does not list small generators unless they are otherwise included in the list under other criteria. 3.2.7 Solid Waste Facilities Two landfills, Mt. Olivet and Renton Highlands, are within the City of Renton. Both are just outside of the ten-year capture zone of the downtown wells. The Mt. Olivet landfill operated from approximately 1977 to 1990. The landfill was permitted to only accept construction, demolition, and land clearing waste. There is no documentation showing that any other waste was accepted. Leachate is not sampled regularly. Sampling in 1996 by Public Health Seattle/King County detected zinc, chromium, petroleum, and thalates in the leachate, all well below concentrations allowed in drinking water. Sampling for groundwater impacts by the landfill has been ongoing since 1990 first by Golder Associates, then Pacific Groundwater Group, and finally the Water Utility since 1995. Contaminants of concern have not been detected in concentrations that clearly indicate contamination by the landfill or that would not meet drinking water standards. Pacific Groundwater has determined that groundwater flow in the shallow aquifer beneath Mt. Olivet Landfill flows to the north/northwest away from City production wells. It is also likely that the shallow aquifer daylights along the step hillside of the North Upland and would be carried by surface waterflows. Given these observations, the landfill does not presently appearto be a significant threat to City wells. The Renton Highlands Landfill is described by the King County Abandoned Landfill Study (Seattle - King County Department of Health, 1985) as a sand and gravel pit converted to a burning dump/landfill, which operated from the 1940's to the 1960's. The study states that ash from burned domestic waste generated by an adjacent housing development was disposed in the landfill. No records were found indicating that hazardous waste had been disposed there. An investigation of this landfill was conducted in 2000 during development review for a new self - storage facility. Brick, glass, asphalt, wood debris, concrete and ceramic materials were found in soil borings to fifteen feet deep. Ecology determined that one area that was contaminated with petroleum did not require remediation. Otherwise, the pit was filled with clean earth materials. Contaminants were not detected in groundwater. 3.1.8 Cemeteries There are no cemeteries within the Renton capture zones. Cemeteries are considered by the USGS to be a possible source of groundwater contamination. Formaldehyde, methanol, arsenic, and mercury may have been used in past or present embalming practices. field studies have shown that dissolved organic carbon, sulfate, chloride, and various nitrogen species may also be associated with cemeteries in concentrations above background (USGS Merit Proposal). Non -point sources include pipelines, storm water infiltration basins, sewers and septic tanks, and transportation sources. 3-5 3.2.9 Petroleum Product Pipelines Two Olympic Pipeline Company (OPL) pipelines run through the City of Renton Aquifer Protection Area Zone 2. The lines transport refined gasoline {60%), diesel (25%), and turbine fuel (15%) from Ferndale -Cherry Point and Anacortes refineries to Seattle, Renton, Sea -Tac, and Portland. Pacific Groundwater Group has produced a separate report, the Draft Olympic Pipeline teak Detection Feasibility Study (1997), which gives a detailed analysis of the potential for pipeline leakage. The OPL pipelines are shown on Figures 3-1 and 3-2. Forty fuel leaks occurred over the entire length of the OPL between 1966 and 1996 Of those 40 leaks, 19 would not be detectable by current, routine monitoring practices. The leaks not detectable by routine practices were mostly those reported by third parties (typically a backhoe operator). Only nine of the leaks occurred on main pipe sections (locations other than facilities or appurtenances). The estimated return period for any OPL leak within Benton City limits is more than 100 years, and for an OPL leak that is NOT associated with a facility or appurtenance, the estimated return period is many hundreds of years. A return period is the average rate of occurrence of an event over a large number of occurrences. These return periods are typical of relatively large, modern, petroleum fuel pipelines elsewhere in the nation. Field experience, and simulations performed with PGG's Renton groundwater model, indicates that the likelihood of OPL contaminating the City's downtown wells is very small, even in the event of a release. Field experience is based on a 1986 leak in which an estimated 80,000 gallons leaked from the OPL in the Maplewood neighborhood and contaminated the alluvial aquifer and the Cedar River. Under the extreme pumping conditions assumed in the MODFLOW modeling analysis, the alluvial (uppermost) aquifer capture zone of Maplewood wells PW -11 and PW -17 extends near to, and possibly includes, the OPL. The capture zone in the alluvial aquifer is important, because the OPL has discharged contaminants to this aquifer. 3.2.10 Storm Water Several governmental agencies in Western Washington have recognized the potential for groundwater contamination from storm water. King County's Surface Water Design Manual (King County 1994) requires impervious liners for wetponds, water quality swales, and other water quality treatment facilities located over rapidly draining soils. Washington Department of Ecology's Storm Water Management Manual for the Puget Sound Basin requires storm water treatment prior to infiltration to protect groundwater quality (Ecology, 1992). The City of Renton's storm water regulations prohibit storm water infiltration within Zone 1 of the City's APA. These regulations also require that water quality facilities and conveyance to such facilities be lined to preclude infiltration if soils are highly permeable. The literature regarding the capacity of storm water infiltration to contaminate groundwater is not consistent. However, it is likely that the capacity is variable and dependent on constituent attributes such as mobility, abundance, and soluble fraction (EPA, 1994); and site attributes such as soil type and depth to groundwater. Constituents likely to pose a threat include mobile organic compounds, pathogens such as bacteria and viruses, and metals with a high soluble fraction such as zinc and nickel. Other studies indicate that pesticides and petroleum hydrocarbons are a concern (Adolfson, 1996). 3-6 3.2. 11 Sewers and Septic Tanks Wastewater disposal systems pose a risk from both naturally occurring organic wastes and toxic chemicals. Discharge of organic wastes occurs wherever septic systems are used. Organic wastes include naturally occurring chemicals such as nitrate that can degrade water quality when discharged in sufficient quantities. Discharge of toxic chemicals into septic tanks is most commonly a problem in commercial or industrial settings with on-site septic systems. A smaller risk exists from septic tank cleaners and other cleaners that could be discharged by homeowners. It is highly unlikely that there are any septic systems within the ten-year capture zone for the downtown wells. They are prohibited in the one-year capture zone for downtown wells and are allowed elsewhere infrequently if City sewers cannot be provided to a building lot. There are septic systems in the unincorporated areas of King County that are primarily in the capture zones for deeper wells for which septic tanks present a relatively low risk. Sewers pose less of a risk since the wastewater is conveyed to a treatment plant. However, sewers can cause contamination if wastewater leaks out of fractured pipes or improperly sealed joints. This contaminant pathway, commonly referred to as exfiltration, may have resulted in groundwater contamination from the dry cleaning facility just west of the downtown wells in 1988. Aquifer protection regulations now require that wastewater collection pipes meet pipeline specifications that prevent leakage of sewage into the aquifer. Older wastewater conveyance that was subject to leakage in the vicinity of the downtown wells has been replaced in recent years with pipe that meets current specifications. Figure 3-2 shows the location of major sewer lines in the City of Renton. 3.2.12 Transportation of Hazardous Materials Trucks carrying hazardous materials travel through the Renton capture zones daily. Highways in the area include Interstate 405 and the Maple Valley Highway. These highways pass through the one-year, five-year, and ten-year capture zones of the Downtown wells, Maplewood wells, and Well 5A. A little -used Burlington Northern rail line crosses the downtown wellfieid and extends up Lake Washington. The rail lines pass through the one-year, five-year, and ten-year capture zones of the downtown and Maplewood wells; and through the five-year and ten-year capture zones of well 5A. The locations of railways in the City of Renton are shown in Figure 3-2. Transportation of hazardous materials poses a risk to groundwater as a result of accidents and the resulting release of contaminants to the ground. Travel speeds, traffic density, volumes and nature of hazardous materials, conditions of roads and tracks, spill containment measures, and driver training are variables defining the degree of risk. Statistics maintained by the WSDOT for 2003 (70% reported) state that: ■ 8.3 percent of reported accidents statewide involve large trucks (compared to 5 percent in 1996, our last report); 3-7 ■ Within the segments of SB 169 and 1405 for which we requested data, nearly 20 percent of accidents involved large trucks. ■ The percent of reported accidents statewide involving large trucks in which hazardous materials were transported was near zero; and ■ The percent of reported accidents statewide involving large trucks in which hazardous materials were released was zero (compared to less than one percent in 1996). These statistics suggest that large truck accidents are on the increase statewide but that there are significantly more accidents involving large trucks in the vicinity of City wells than elsewhere, perhaps due to the nature of local commerce. The statistics also indicate that the risk of hazardous material spills from truck accidents is very low. There could be reporting errors and other confounding factors in this data. Improvements in packaging and transport of hazardous materials could also be a factor. We were unable to obtain data on the percentage of large trucks transporting hazardous materials. However, it seems unlikely that no accidents involving large trucks carrying hazardous materials would have occurred. It also seems unlikely that no hazardous materials would be released given the impacts to fuel tanks during an accident. So while data suggest a low risk, they aren't conclusive. The rail line adjacent to the downtown wells receives limited use by freight and a recreational "dinner" train. It is unlikely that hazardous materials are transported on this line. Its primary use is to transport airplane parts from Boeing's Auburn plant to its Renton plant. While a derailment can rupture a fuel tank, our experience locally has been that such spills are readily cleaned up since they are of limited size. However, a derailment very near to our downtown wellfield could cause sudden and severe short-term water supply disruption. The City has contingencies to deal with such an event. Please refer to Chapter 5 for further discussion. 3.3 SOURCE RISK ASSESSMENT An assessment was performed to facilitate the prioritization of future risk mitigation efforts. Sites and non -point sources posing relatively high risks to city wells are identified in Table 3-2. The data used to create this Table have not been updated in 2004 because the basis of the table is qualitative in nature and the types of contaminant sources and contaminants have remained fairly constant. The one significant exception is that risk has been reduced within the one-year capture zone for downtown wells since the requirement to reduce hazardous materials in Zone 1 to 500 gallons came due in October 2002. One gas station left the area and Stoneway Concrete built a new plant outside of the capture zones for City wells leaving less than 500 gallons at their site within Zone 1. The risk ranking method considered the following variables: • Release likelihood • Volume of contaminant • Mobility/persistence/likely concentration relative to MCL • Proximity to well • Number of sites 3-8 Values of 1, 5, or 10 were assigned to the release, volume, and mobility variables. The values were assigned as follows: A release likelihood of 10 was assigned to Confirmed and Suspected Contaminated Sites, and the transportation category. USTs, LUSTS, heating oil tanks and Facilities Storing Hazardous Materials were assigned a risk value of 5, although, LUSTs may pose less risk than USTs because LUSTS have been identified and are managed by Ecology. Other sites were given a release risk value of 1. • A volume factor of 10 was assigned to large contaminant volume sites such as pipelines, stormwater, Confirmed and Suspected Contaminated Sites, sewers and solid waste facilities. USTs, transportation and Facilities Storing Hazardous Materials were assigned a factor of 5 and small volume sites such as heating oil tanks and RCRA generators were assigned a factor of 1. A mobility/persistence factor of 10 was assigned to site categories likely storing chlorinated solvents. Those sites include Confirmed and Suspected Contaminated Sites and RCRA generators. Site categories likely storing gasoline (USTs, LUSTS, pipelines, transportation), Facilities Storing Hazardous Materials, sanitary sewers and septic systems, and sites with unknown chemicals were assigned a factor of 5. Other facilities releasing only inorganic contaminants or non -gasoline fuels were assigned a factor of 1. • Either the actual number of sites in the database or the size of a potential non -point source release area was used to quantify the number of sites within each capture zone. For a given travel time capture zone, risk was assigned by multiplying the number of sites by release, volume, and mobility factors, and then dividing by the capture zone travel time in years (1-, 5-, or 10 -years). Capture zones were used to represent distance, and are the denominators in the risk equation because risk is inversely proportional to distance. No consideration was given to relative distance within a travel time capture zone. Relative risks were assigned as Relatively High, Medium, or Relatively Low based on the result of the risk calculation. Despite the quantitative approach, the results of the risk analysis should be considered qualitative because of the considerable uncertainty inherent in any ranking of this nature. Further error was induced because the capture zones depicted are the furthest extent from which groundwater could travel in a given time and enter the well regardless of depth. Therefore, although contamination generally originates at the surface, the capture zone depicted may be in a deeper aquifer, which is vertically separated from the source of contamination. Based on this neglected factor alone, sources near the downtown wells pose a greater threat than similar sources near the Maplewood wells. 3.3.1 Downtown Wells The downtown wells are subject to the highest risk of groundwater contamination due to the density of population and industry in their capture zones. Table 3-2 indicates that the contaminant sources designated "Relatively High" are in the downtown capture zones. The sources posing relatively high risk are Confirmed and Suspected Contaminated Sites, USTs, LUSTS, heating oil tanks, Facilities Storing Hazardous Materials, and transportation. Most of the 61 USTs and LUSTS within the 1 -year and 5 -year capture zones are associated with automotive businesses and likely contaminants are petroleum hydrocarbons and possibility solvents. There are four Confirmed and 3-9 Suspected Contaminated Sites within the five-year capture zone of the downtown wells. Two are automotive related sites and the one is the Renton School District warehouse_ Transportation of hazardous materials poses a high relative risk to the one-year capture zone of the downtown wells. The high risk is due to the short (4 year) return period. Four incidences of contamination have occurred within the capture zone of the Downtown wells: the Texaco leak of 1988, the PCE detection of 1988, and the Stoneway incident of 1997. Each is described below. 3.3.1.1 Texaco, 1988 In 1988, Well 3 was used only as a standby well and has not been used since the contamination incident. Well 3 is located at the northeast tip of Liberty Park, across the street from a Texaco service station. Routine sampling and verification sampling in early January 1988 detected concentrations of dissolved hydrocarbons in Well 3. The City installed a network of monitoring wells around Well 3 and around the Texaco station to assess the source of the contamination. The highest observed concentrations of benzene, toluene, and xylene were 100 parts per billion (ppb), 110 ppb, and 120 ppb respectively. Texaco located the source of the leak in a splice in the gasoline dispensing system liner. Remedial measures and repairs ultimately undertaken included: • Nine monitoring wells were installed • Two recovery wells were installed and pumped to sewer • Well 3 was pumped to Cedar River • Soil vent wells were installed • Standby motor for Well 3 was purchased • Liner was reinstalled in the line area and spliced by factory trained representative • Liner trenches were regraded to direct leaks to the sump. • Leak detection system was substantially improved 3.3.1.2 PCE Detection, 1988 During sampling related to the Texaco incident of 1988, PCE was detected in downtown monitoring wells. The following two paragraphs summarize the occurrence of the PCE in the downtown well field in two discrete periods: PCE was detected in six City of Renton monitoring wells (MW -6, MW -18, MW -19, MW -21, MW -22, and MW -24 in the downtown aquifer in the spring of 1988. The contaminated wells are northwest of wells RW -1,2,3. By 1990, PCE concentrations had declined to below detection limits effective at that time (0.5 ppb) after a dry cleaning facility stopped discharging PCE contaminated water to a sanitary sewer near the contaminated wells, and after the sewer was lined. Based on these data it was concluded that the likely source of PCE in the downtown wellfield in 1988 was the dry cleaner. Dry cleaners are typically listed as RCRA generators in the database downloaded for this project because they RMIC generate waste solvent; however, they may also be small quantity generators that would not occur on the Ecology database. Dry cleaners are also Facilities Storing Hazardous Materials. From 1990 to 1997, continued monitoring indicated that PCE concentrations were barely detectable in six monitoring wells (MW -6, MW -19, MW -20, MW -21, MW -22, MW -24) with the new lower detection limit of 0.2 ppb. Only wells MW -6 and MW -20 had concentrations above 0.5 ppb. 3.3.1.3 PCE Detection, 1997 In lune 1997, PCE was detected in PW -8 at 0.55 ppb after an extensive period of time with wells RW -1, 2, 3 as lead wells. This indicated a new source or changed PCE condition in the aquifer. The City switched to PW -8 as the lead well to protect wells RW -1, 2,3. By August 1997, PCE concentration in PW -8 rose to 3.6 ppb and the City switched back to a RW -1, 2, 3 lead. In September 1997, PW -8 and MW -18 reached unprecedented PCE concentrations of 4.4 and 5.6 ppb, respectively, and PCE was detected at MW -31S (near Stoneway Concrete — southeast of the production wells) for the first time. Therefore, PW -8 began pumping to waste continuously and wells RW -1, 2, 3 were placed on first -call to supply the City drinking water. The objective was to use PW -8 to protect wells RW -1, 2, 3 while RW -1, 2, 3 supplied the City water. Also, this pumping arrangement was planned to create a steady-state flow field that would enhance the likelihood of locating the new PCE source. Pacific Groundwater Group conducted a study to assess the source of the RCE in the spring of 1998. Further information is contained in a report titled Stoneway Tetrachloroethene (PCE) Assessment, Renton, Washington, 1988. The study included use of the MODFLOW groundwater flow model and sampling of groundwater, soil, sewer, and concrete waste. The study concluded that the PCE detected in PW -8 in 1997 probably entered the ground on the Stoneway Concrete property. The model estimated a groundwater travel time on the order of 1 month between the suspected source areas and PW -8. Results of the sampling indicated that a source of mixed chlorinated hydrocarbons, non - chlorinated hydrocarbons, and inorganic contaminants exists within the concrete wastewater ponds and an area where waste soils are mixed with waste concrete from the ponds. The organic chemicals detected include those found in fuels, solvents, paints, and other liquid organic products. The inorganic chemicals are probably directly associated with cement manufacturing. Near the source area, the groundwater plume contains both organic and inorganic contaminants. The organic, non -chlorinated contaminants like those in fuels (toluene, xylene, and naphthalene) generally move more slowly and degrade more rapidly than the chlorinated contaminants like PCE. Acetone and the ketones move fairly rapidly but they also degrade rapidly. Therefore, these compounds are not detected downgradient. PCE is the contaminant of greatest concern because it is relatively mobile, persistent, and it is migrating at a concentration that is high relative to the drinking water maximum concentration level, or MCL of 5 ppb. The report included recommendations to protect the City's source of groundwater including source removal, identification of best management practices, groundwater monitoring, and groundwater remediation. Stoneway implemented several actions to reduce the likelihood of further releases, including cessation of soil/concrete mixing on site. However, more extensive evaluations, and possible extensive re-engineering of wastewater management facilities may be 3-11 required to resolve Ecology Notice of Violation No. DE 98WQ-N272 dated January 22, 1999. This violation cites State Water Quality Standards and Sand and Gravel General Permit WAG SO -3301, which prohibit all groundwater and surface water discharges. In addition, the City has determined that the land use at Stoneway Concrete is incompatible with the Aquifer Protection Area. In summary, tetrachloroethene contamination at the source and in groundwater appear to be abating; however, inorganic contaminants continue to degrade groundwater quality very near City drinking water wells and this contamination requires abatement. Stoneway Concrete is presently regulated by the City as an APA facility. However, it is also listed as an UST and RCRA site in the Ecology database downloaded for this project. It is believed that the UST and RCRA designations are no longer accurate. 3.3.1.4 Sewer tine Damage 2001 In December 2002, a geotechnical consultant hired by the City of Renton Transportation Division to do soils investigation for the widening of Maple Valley Highway augered a 6 -inch hole through King County's 42 -inch Cedar River Trunk sewer line in Cedar River Park near Well 9 based upon an incorrect locate. Well 9 had not been in use for some time at the time of the incident. It was initially thought that hole extended only through the top of the pipe. One day later it was determined that the hole extended through the bottom of the pipe allowing wastewater to be discharged to the subsurface. King County immediately installed a temporary plug to seal the hole in the pipe. A permanent repair was completed within approximately ten days. The County's drilling contractor installed a temporary monitoring well within a few feet of the break. The County took samples from this well several times over the subsequent week and detected low levels of sewage -related contamination on several occasions. Wastewater was not released to the surface of the ground or to any adjacent surface water body. The Water Utility contracted with our geohydrology consultants, Pacific Groundwater Group (PGG), to assess the potential risk of contamination to the City drinking water supply. Using our computerized model of groundwater flow, PGG estimated the probable direction of flow and time of travel of potential contaminants in relation to operating wells. Conservative estimates indicated that it would take a number of months before contaminants could reach the City's wells. This would give us time to investigate the release and implement contingencies, if needed. On December 20, PGG conducted an investigation of groundwater quality in the immediate vicinity of the break by using geo-probes to collect groundwater samples. Sewage -related contamination was not detected. It was concluded that the likelihood of health threats at water supply wells was very low and it was expected that the City would be able to operate wells using normal procedures. As an extra precaution, the Water Utility sampled emergency supply well EW3 on February 4, 2003, to confirm earlier results. The Utility continued to sample wells according to Washington Department of Health requirements and did not detect sewage contamination. 3.3.2 Maplewood, Springbrook, and Well SA 3-12 USTs, heating oil tanks, Facilities Storing Hazardous Materials, pipelines, septic/sewer and transportation pose medium risk to the Maplewood wells. There are six registered USTs and LUSTs within the Maplewood 1 -year and 5 -year capture zones and two Confirmed and Suspected Contaminated Sites within the 5 -year and 10 -year capture zones. Only sewers/septic rank as medium risks to Springbrook Springs. There is only one point source site (an UST) within the 1 -year and 5 -year capture zones of Springbrook Springs. Sewers/septic systems and transportation pose medium risk to Well 5A. In addition, there is one UST within the 1 -year capture zone. In the 5 -year capture zone, there are three UST's (all gas stations) and five Facilities Storing Hazardous Material. 3.4 NOTIFICATION OF OWNERS AND AGENCIES Department of Health (DOH) regulations require that the City notify owners and operators whose property or operations may pose a risk of groundwater contamination, that they are located in the capture zones identified in Chapter 2 (Figures 2-3, 2-5 2-6 and 2-17). The city is also required to notify regulatory agencies and local governments of the boundaries of the capture zones. The Water Utility notified the owners and operators of the sites listed in Table 3-1 of their location in the capture zones shown. The letter of notification is included in this report as Exhibit 3-1. The Water Utility sent a letter, map of capture zones, and copy of Table 3-1 to agencies that have authority over potential sources of contamination. The mailing list is included in this report as Exhibit 3-2 and the letter is included as Exhibit 3-3. Adjacent local governments will receive a copy of the Water System Plan including the Wellhead Protection Plan. 3-13 Table 3-1: Potential Point Sources of C ontamination in Captut•e Zones - 2012 Update SITE NATE STRIEETSTRIElETKAW I CNMAW ZDW TMVFL71MA F AM SIfE UST Kennydale Chervn K*nnydale Shell 1416 1416 N3Cth St N 30th St 5A SA S' .,,. 5 Y J Mlar5pil Residence MIC Conyie� AUCs Services Park- P—t RENTON SCW)CL DISTRICT 0403 421, 1229 Mlounrarn View Av N Bransm Ways WV01.

As part of this program, we have mapped the area frorn which groundwater travels to our wells and spring within a period of ten years. This area is referred to as a Wellhead Protection Area. Following the mapping of the Wellhead Protection Area, we conducted an inventory of potential sources of groundwater contamination within the area. To our best knowicdge, your business or site IMS the potential to affect our customer's drinking water quality. The criteria for this determination arc that the activity involves the use or storage of hazardous chemicals or it has been determined that the site is already contaminated. As required by the Washington Department of Health, we are notifying you of your location in the Wellhead Protection Area. YOU may already he taking strong measures to prevent the release of chemicals to the ground and storm drains. If there is room for improvement in your practices, we hope that this notification will inspire you to take stronger precautions. Also as required by state law, we have reported our findings to regulatory agencies that may have authority over the types of activities that occur at your business. "Pito intent is that, during their routine contacts with you, they will be aware that containment of chemicals is of particular concern. These agencies should be able to assist you with proper management of your business or site to prevent groundwater contamination. If your site is already known to be contaminated and cleanup is not in progress, we strongly encourage you to enter the Voluntary Cleanup Program with the Washington Department of Geology to facilitate rapid and adequate cleanup. Please contact Steve Alexander, Toxics Cleanup Supervisor, at 425-649- 7054 for Further information. Please contact me at 425-430-7211 (eboatsman(dci.renton.wa.uc) should you have questions about our Wellhead Protection Program or wish to discuss ways in which we can work together to protect Renton's drinking water. 1 can also help you get in contact with agencies that have programs to assist you.

Letter of Notification to Agencies and Local Governments. (date) (name, address) SUBJECT: RENTON WELMEAD 1'ROTECrj,1Ori AREA Dear: The purpose of this letter is to notify you of the location of City of Renton Wellhead Protection Areas as required by the Department of flealth (WAC 246-290-135). The City provided water to an estimated 54,900 people in the City limits from 14,630 service connections in 2003. This is in addition to 551 connections outside of the City limits. We operate four distinct water supplies as shown on the enclosed map_ The contamination susceptibility rating assigned by the Department of Health to our water supplies is: Downtown wells: moderate to high susceptibility Springbrook Springs: moderate to high susceptibility Maplewood wells: low susceptibility. Well 5A: low susceptibility The enclosed maps show the 1, 5, and 10 -year capture zones for our wells and spring source. The boundary of the 10 -year capture zone constitutes the boundary of our Wellhead Protection Area for each source. Groundwater contamination that occurs within Wellhead Protection Areas has the potential to reach our drinking water supply, Contamination that occurs within the capture zones for the downtown wells and Springbrook Springs has a high probability of reaching our water supply due to the susceptibility of these sources to contamination and to our primary dependence upon these sources. It is therefore of great importance to the City that all reasonable steps be taken to ensure that sources of contamination and/or land uses regulated by your agency do not contaminate our customer's drinking water supplies. Please contact me at 425-430-7211 (cboalsman cr ci.renton.wa.tts) should you have questions about our Wellhead Protection Program or wish to discuss ways in which we can collaborate to protect Renton's drinking water. We thank you for your support and cooperation- Sincerely, ooperationSincerely, Carolyn boatsman Aquifer Protection Coordinator 3-20 4. CONTINGENCY PLAN FOR LOSS OF THE DOWNTOWN AQUIFER The Contingency Plan's purpose is to provide "for the location and provisions of alternate drinking water supplies for each public water system in the event of well or well field contamination" (WAC 246-290-100). The Washington Department of Health (DOH) Wellhead Protection Guidance Document, June 2010, identifies six key elements to be included in the Plan to ensure that Renton's "water system, and local officials are prepared to respond to emergency situations and able to provide alternative sources of drinking water." Contingency Plan Elements: • Identify maximum water system capacity in relation to source, distribution system, and water rights restrictions. Assume loss of largest groundwater source. Evaluate the water system's expansion options within current water rights and availability. • Identify existing or potential interties with other public water systems and evaluate the ability to deliver water if the largest groundwater source is lost, including costs associated with the purchase or delivery of alternate supplies. • Evaluate current procedures and make recommendations on contingency plans for emergency events. * Identify future potential sources of drinking water, and describe quality assurances and control methods to be applied to ensure protection of water quality prior to utilization as a drinking water supply. + Maintain a current list of appropriate emergency phone numbers 4.1. Maximum Water System Capacity. Renton's supply is derived from five water sources: the Cedar Valley Aquifer, Springbrook Springs, the Maplewood Aquifer, the recharge area for Well 5A and SPU supply interties. For the City's primary supply, it maintains and operates six wells within the Cedar Valley Aquifer and three wells within the Maplewood Aquifer. It also has Springbrook Springs, a single artesian spring, and Well 5A, which is the only well that the City operates within that particular recharge area. The largest source would be the Downtown Aquifer, which consists of wells RW1, RW2, RW3, PWB, and PW9. The capacities of the downtown aquifer wells are presented in Table 5.1. Well EW3 is an emergency backup which would also be rendered useless as it is also in the downtown aquifer. The contamination or disruption of this source would result 5-1 in a loss of 11,300 gpm (16.28 MGD). The City's wells not in the downtown aquifer are presented in Table 4-2, their total capacity is 6,300 gpm (8.7MGD). Table 4-1. City wells used for primary supply that are located in the downtown aquifer Source Capacity (gpm) Capacity (MGD) RW1 2,200 3.17 RW2 2,200 3.17 RW3 2,200 3.17 PW8 3,500 5.04 PW9 1,200 1.73 (EW3)* 1,500 (1.44)* Total capacity to be replaced 11,300 16.28 *Emergency use only, when RW -1, RW -2, RW -3, PW -8 or PW -9 is out of service. 5-2 Table 4-2.

Expansion Options The City has 13 water right certificates and 5 permits. A thorough discussion of the City's water rights is presented in Chapter 6, Water Supply, Water Rights, and Water Quality. A summary of the City's existing water rights for municipal supply is presented in Table 6-1. The total instantaneous flow rate from the certificated rights is 15,152 gpm. The annual rights equal 14,809 acre feet per year, was set by DOE and is less than the sum of the City's annual rights shown on its certificates. Currently the Maplewood wells are used as alternate sources only but the City may try perfecting water rights certificates for these wells. For the current planning period, the City's forecasted water rights are the same as its existing water rights. 4.3 Interties The capacity available from alternate City wells plus emergency interties with adjacent suppliers is 19,495 gpm (26.15 MGD). Given average high -day demand of 14.14 MGD (Chapter 3), this capacity would be adequate to supply the City's customers. Implementation of the Water Shortage Response Plan would help reduce demand and further ensure the City's capability to supply customers on a long-term basis. 5-3 The City maintains emergency funds in the capital account of the Water Utility to help defray the costs of loss of a wellfield. In addition, the City has invested in improvements to transmission, pumping, and storage to accommodate production of water from the alternate wellfields in the event of an emergency. Table 4-3.

These documents address both long and short term water needs. The City 5-4 also has developed a Disaster Recovery Plan to establish policies, guidelines and procedures to quickly recover from the impacts of disasters. In grief, short and long term loss will be addressed: A. Short Term loss of the Downtown Wellfield Upon loss of the downtown wellfield due to contamination, the City will: 1. Immediately switch production to City wells not located in the contaminated aquifer; 2. Implement the Water Shortage Response Plan; 3. Activate emergency sources; 4. Run the groundwater model to aid in tracking and identifying the contamination plume; and 5. Increase monitoring in affected production and monitoring wells. B. Long Term Loss of the Downtown Wellfield If it appears that the wellfield will be unavailable for a long period of time, the City will: 1. Continue the use of alternate wellfields and emergency sources; 2. Modify the Utility's Capital Improvement Plan to improve distribution system zone -to -zone flow from alternate wells and emergency sources; 3. Assess the feasibility of treatment for the contaminated wellfield; 4. Utilize longer-term supply from Seattle; 5. Assess aquifer storage and recovery options; 6. Assess the feasibility of increasing storage for use during peak demand. 4.5 Future Potential Sources The City has a 50 -year partial requirements water supply contract with Seattle Public Utilities (SPU). Under this contract SPU will provide the city with sufficient source to meet long term needs. It is not likely that current water rights can be increased or expanded in the near future. 4.6 Emergency Contacts and Phone Numbers Calling 911 elicits response to hazardous materials spills in the well capture zones, as well as the entire City by the City of Renton Fire Department HAZMAT Unit. The Fire Department will respond as necessary and will notify the Water Utility if a release has occurred in the Aquifer Protection Area. The City of Renton Office of Emergency Management has developed a Comprehensive Emergency Management Plan to prepare for a disaster in the community. This plan 5-5 provides a framework on how government will prepare, respond, and recover from an emergency. Some of the hazards the City of Renton is vulnerable to include; earthquakes, fires, flooding, wind, snow, ice storms, hazardous materials releases, dam failure, landslides, and volcanic eruptions. The King County Local Emergency Planning Committee of King County (LEPC) would coordinate response to a major disaster such as a severe earthquake. The Water Utility's role is to provide information to Fire Department staff about drinking water wells and the aquifer, to respond to selected spills that are of particular concern, and to follow up to ensure that long term remediation, where necessary, is adequate to protect drinking water. PHONE NUMBERS Local Hazardous spill or other water emergency: Fire — 911 King County: King County has regulatory oversight for small public water systems (Group Bs) serving 2-9 connections — Washington State Department of Health regulates larger (Group A) systems such as Renton.

AQUIFER PROTECTION PROGRAM 5.1 Introduction The Renton Water System Plan recommended an aquifer protection program in 1983. In the same year a tanker truck carrying diesel fuel overturned on 1-405 near the downtown wells and spilled its contents. While this incident did not result in contamination of the aquifer or wells, it did motivate the City to begin a serious effort to identity risks to the Cedar Valley Aquifer and measures to protect the aquifer. The Wellfield Protection Study completed in 1984 characterized the hydrogeology of the aquifer, identified potential sources of contamination, and recommended a program to protect the aquifer. The City has implemented recommendations from the study in addition to other elements of a risk management program. The City, assisted by citizens and with outstanding cooperation by the business community, continues to develop and implement a comprehensive aquifer protection program. The Water Utility leads the program but nearly every other City department has some role, major or minor, in protecting the aquifer. Table 5-1 is a chronology of key actions and events in the development of the Renton Aquifer Protection Program. Major components of the program are briefly described below. 5.2 Aquifer Protection Area Aquifer protection regulations are in effect and other aspects of the program are emphasized in the Aquifer Protection Area (APA), which is comprised of the 1,5 and 10 —year capture zones. The APA was adopted by the City Council in 1988 and revised in 2002. Table 5-2. Renton Municipal Code Chapters Relevant to Aquifer Protection Citation section Title 1-3 Remedies and Penalties 4-1 Administration and Enforcement 4-3-50 Critical Areas Regulations (A,B,C, D and H) 4-4-0300 Construction Activity Standards 4-4-060L4 Fill Material 4-5-120 Underground Storage Tank Secondary Containment Regulations 4-6-03oE2,3 Drainage (Surface water) Standards 4-6-040J Sanitary Sewer Standards 4-8-120 Submittal Requirements 4-9-015 Aquifer Protection Area Permits 4-11 Definitions 5-5-5 Requirements for Business License Applications in an Aquifer Protection Area 8-5-22 wastewater Requirements that Apply within Zones 1 and 2 6-1 Currently, the APA includes three zones as follows: Zone 1: This zone encompasses the 1 -year capture zone for the downtown wells. Regulations adopted for this zone provide the strongest protection for the area that is very close to the most important and vulnerable wells. Zone 1 Modified: This zone encompasses the 1 -year capture zones for the Maplewood Wellfield and Springbrook Springs, both of which are partially outside of the City limits. Regulations are somewhat less strict than those in Zone 1 and are intended to provide appropriate protection for important wells/springs that are deep and/or partially protected by intervening layers of relatively impermeable earth materials. • Zone 2: Regulations for this zone provide a level of protection adequate for areas that are further away from the most important sources but still within the capture zone or for deep backup wells. Zone 2 encompasses: o The portion of the capture zone for downtown wells that lies between the 1 -year capture zone boundary and the City limits; o The portion of the capture zone for Well 5A that lies within City limits; and a The portion of the capture zone for Springbrook Springs that lies between the 1 - year capture zone boundary and the 10 -year boundary. The City's regulatory authority is limited to jurisdictional boundaries but it works with other jurisdictions to protect portions of capture zones that lie outside of City boundaries. Designating zones for areas outside of the city limits provides the following benefits: • Areas falling within wellfield or springs capture zones are automatically included in protected areas upon annexation; and • The City has a stronger position from which to negotiate protection with neighboring land use jurisdictions. Overall, the current APA does not coincide with the boundaries of the 1, 5, and 10 -year capture zones delineated for this report and shown on Figure 2-1. Delineation of the new capture zones is documented in Chapter 2 of this report and 2006 WSP Appendix Q. Application of the APA regulations will be transferred to the updated zones. 5.3 Compliance with State Wellhead protection Requirements The City complies with Wellhead Protection requirements for Group A Public Water Systems contained in Chapter 246-290-135(3) WAC and administered by the Washington Department of Health. Compliance is documented in chapters 2, 3, and 4 of this report and section 5.7. These chapters address delineation of capture zones, identification of potential sources of contamination, notification of owners and regulators of potential contamination sources, and 6-2 verification that the City could continue to supply customers in the event of loss due to contamination of its primary source of water. Section 5.7 addresses coordination with emergency responders. 5.4 Sole Source Aquifer Designation The Water Utility petitioned the Environmental Protection Agency (EPA) in 1986 for Sole Source Aquifer designation of the Cedar Valley Aquifer. This designation, which was granted in 1988, protects an aquifer from potential contamination or depletion which could be caused by by development that is partially funded by the federal government. The EPA reviews projects partially funded by the federal government to determine if the aquifer might be negatively affected. Appropriate mitigations may be required or a particularly damaging project could be halted altogether. Additional benefits of Sole Source designation include increased public awareness of the value of the water supply and increased attention by state and local agencies that regulate potential sources of contamination. Sole Source designation was instrumental in the Water Utility's successful negotiation with the Washington State Department of Transportation (WSDOT) to provide protection of the aquifer during construction of the S -Curve realignment of 1-405 in the early 1990's. The WSDDT agreed to implement on-site best management practices and fund monitoring of construction practices by a third party. The agreement also included design changes that would direct hazardous materials and runoff to lined detention ponds adjacent to the freeway. These ponds prevent infiltration and hold spilled hazardous materials long enough to allow removal. This protects the production wells next to the freeway and the Cedar River, which passes underneath. The ponds have contained significant diesel spills at least twice since their construction in 1993. 5.5 Aquifer Awareness Program The Water Utility has implemented a public education program since 1989. This program emphasizes awareness of the physical characteristics of the aquifer and individual behaviors that protect it. This program includes aquifer model demonstrations at school science fair nights, an educational booth at the Renton's River Days festival, and a conservation web page. Each year our Consumer Confidence Report contains educational information to help customers where their water comes from and how they can help protect the aquifer. Renton has been designated a Groundwater Guardian Community by the National Groundwater Foundation for 16 years. The Renton Solid Waste Utility also offers educational programs that, among other goals, promote aquifer protection. Their focus is on recycling and waste reduction, including minimizing the use of products that are toxic and considered hazardous waste when disposed. Solid Waste has created a demonstration garden in which pesticides are not used and teaches popular Green Gardening classes. 6-3 5.6 Aquifer Protection Regulations Aquifer protection regulations are in effect in the Aquifer Protection Area (APA). The Renton City Council adopted these regulations in September 1992 after much community input and debate. The regulations have been substantially amended two times, once in 1998 and again in 2002. This section describes the most important features of the regulations. Table 5-1 summarizes location of relevant Renton Municipal City code. Table 5-1. Renton Municipal Code Chapters Relevant to Aquifer Protection RMC Citation Chapter Title 1-3 Remedies and Penalties 4-1 Administration and Enforcement 4-3-050 Critical Areas Regulations 4-4-03007 Construction Activity Standards 4-4-060L4 Fill Material 4-5-120 Underground Storage Tank Secondary Containment Regulations 4-6-030E2 Drainage (surface Water) Standards 4-8-120 Submittal Requirements 4-9-015 Aquifer Protection Area Permits 4-9-250 Variances, Waivers, Modifications and Alternates 4-11 Definitions 5-5-5 Requirements for Business License Applications in an APA 8-5-22 Wastewater Requirements that apply within Zones 1 and 2. 5.6.1 Hazardous material restrictions Limited in Zone 1: • Hazardous materials limited to: a 500 gallons (5000 pounds) at new and existing facilities; o Containers no larger than 5 gallons (at new facilities); and o No more than 150 gallons to be opened and handled on the premises (new facilities). Banned in Zone 1: • Tetrachloroethylene (dry-cleaning fluid) Zone 1 Modified: Hazardous materials limits and ban the same as Zone 1 except that the 500 gallon limit is in effect only for new facilities. 6-4 The City prohibits the use, storage, or handling of more than 500 gallons of hazardous materials at facilities, usually businesses, within Zone 1 of the Aquifer Protection Area. All facilities were required to be in compliance within ten years of the effective date of the ordinance. In addition tetrachloroethylene, commonly used for dry cleaning, was banned. As a result of the above, three businesses either closed or relocated: a drycleaner, a gas station, and a concrete batch plant/truck fueling and maintenance facility. Very early on, the City offered limited financial compensation for relocation or closure. Only the dry cleaning facility closed within the time frame that funding was available. The definition of a hazardous material is consistent with the Uniform Fire Code and the Occupational Safety and Health Administration, and consists of a classification system that assigns a chemical to a hazard category based upon it's properties. Hazardous materials include physical hazards (e.g. explosives, compressed gases, flammable and combustible liquids, oxidizers, and organic peroxides) and health hazards (e.g. toxic substances, corrosives, carcinogens, and irritants). While the hazardous material definition includes an unnecessarily broad array of substances to be regulated for aquifer protection purposes, the City wanted to collect just one inventory of hazardous materials from facilities for purposes of both the Fire Prevention Bureau and the Water Utility. In practice, the materials that are found at regulated facilities are usually those that the Water Utility would be concerned about, e.g. petroleum products, solvents, paints, pesticides. In calculating a total for purposes of determining whether the threshold is surpassed, the Utility exempts those substances that do not present a risk. 5.6.2 Land Use Restrictions in the Aquifer Protection Area In addition to the above limits on hazardous materials in Zone 1 of the APA, the City has adopted regulations prohibiting some land uses. The Water Utility coordinates with land use planners, building permit reviewers, and staff responsible for issuing business licenses to ensure that the prohibited uses are not inadvertently allowed. The following summary of land use restrictions is provided: Prohibited in Zone 1 and Zone 1 Modified: • New underground storage tanks containing hazardous materials (one small existing underground tank remains and is slated for removal) • New heating systems using fuel oil except commercial using existing above -ground waste - oil tanks (one existing commercial using underground fuel storage remains) Prohibited in Zone 2: New heating systems using fuel oil stored in underground storage tanks Prohibited in Zone 1, Zone 1 Modified, and Zone 2: New on-site sewage disposal systems (Existing in Zone 1 required to connect; New allowed in Zone 1 Modified and Zone 2 if sanitary sewer unavailable) • New solid waste landfills and transfer stations 6-5 • Hazardous waste treatment, storage, and disposal facilities or recycling facilities • New petroleum product pipelines In addition to specific uses that are not allowed, the Water Utility has broad authority to review any proposed use in the APA and assess whether aquifer water quality is likely to be impacted. Such uses may be denied. 5.6.3 Exemptions The following uses, categories of hazardous materials, and types of facilities are exempt from most regulations: • Government emergency preparedness and response • Hazardous materials of no risk to the aquifer + Retail sale of small containers (5 gallons or less) • Residential use • Fuel and equipment tanks * City water treatment processes • Multi -family dwellings, hotels, nursing homes • Facilities with 20 gallons or less on premises 5.6.4 Regulation of Facilities Handling and Storing Hazardous Materials The Water Utility regulates facilities located in the APA that handle and store hazardous materials. The purpose of this program is to ensure that hazardous materials are handled in a manner that prevents their release to the environment where they may contaminate the aquifer. Regulations are the same in Zones 1, 1 Modified, and 2 with minor exceptions. An annual Operating Permit is required to operate a business or other facility located in the APA if more than twenty (20) gallons of liquid hazardous materials are stored, handled, treated, used, or produced on site. The corresponding threshold for solids is two hundred (200) pounds. Facilities required to obtain a permit include but are not limited to businesses, public facilities, schools, hospitals, and parks. There is no fee for an Operating Permit, which is obtained after an annual inspection confirms compliance. Operating permits can be suspended or revoked for non- compliance. The approximately 70 facilities that are subject to Operating Permit requirements have complied and obtained their permits. No permits have been suspended or revoked to date. Most owners see the importance of protecting the aquifer and seem to value their role in protecting a precious natural community resource. Water Utility staff takes a flexible, educational approach in implementing this program. Referrals to the Local Hazardous Waste Management Program in King County are often made for purposes of bringing greater expertise to bear on questions that the business owner may have, for gaining financial assistance in purchasing secondary containment or in identifying and disposing of hazardous waste, and for gaining recognition from the Envirostars Program for those facilities that do an outstanding job. 6-6 Owners are also encouraged to cooperate with and avail themselves of the knowledge offered by the City Fire Prevention Inspector. Requirements of the Fire Code, if implemented, partially meet requirements of the Aquifer Protection Code. Aquifer protection requirements are consistent with best management practices to protect the environment and the health and safety of workers. Therefore, we find that many facility owners are already implementing many aquifer protection requirements before we contact them about the requirement to obtain an Operating Permit. Aquifer protection requirements include: 1. Annual Operating Permit application 2. Annual Hazardous Materials Inventory Statement 3. Secondary containment of hazardous materials 4. Monitoring of hazardous material storage areas 5. Spill response capability 6. Spill reporting 7. Legal hazardous waste disposal and record keeping 8. Employee training 9. Complying with pesticide reporting requirements and fertilizer application limits/reporting requirements 10. Obtaining and complying with requirements of a Closure Permit when closing the facility 11. Zone 1 only: Facilities that were in existence when the regulations were adopted may be required by the City, according to specific criteria, to monitor groundwater, pave sites subject to contamination, and improve stormwater management. 5.6.5 Contaminated Sites The Water Utility keeps abreast of progress on cleanup of contaminated sites listed on the Department of Ecology's Confirmed and Suspected Contaminated Sites List and Leaking Underground Storage Tank List. The Utility coordinates with Ecology on cleanup of those sites that are of greatest concern to the City. Ecology has been very helpful in placing a priority on such sites. The City generally relies on the state program for ensuring cleanup of contaminated sites. To augment the state program, the City has adopted regulations prohibiting unauthorized release of hazardous materials. Regulations also require that the person responsible or the owner of the property on which the release has occurred report such releases to the Water Utility. Regulated facilities (those located in the APA that require an Operating Permit) are required to provide detailed information to the Utility regarding releases, including the cause and methods to prevent future releases. Cleanup progress reports must be provided until the site meets Model Toxics Control Act standards and, according to best available evidence, does not put the City drinking water supply at risk of failing to meet state standards. 6-7 5.6.6 Construction Activity Standards The City has adopted construction activity standards, effective only in the APA, that are designed to protect the aquifer. These apply if construction vehicles will be refueled on site and/or the quantity of hazardous materials that will be used or stored on the construction site, exclusive of the quantity of hazardous materials contained in fuel or fluid reservoirs of construction vehicles, will exceed twenty gallons. The Development Services Division implements these standards with the assistance of the Water Utility. A description of refueling activities that will occur on the site and an inventory of hazardous materials expected to be present is submitted to the Development Services Division prior to issuance of a permit regulating any construction activity in the APA. Permit applicants that are subject to the standards must submit a hazardous materials management statement that describes how construction activity standards will be met. The permit will not be issued until the statement is approved. The following is a summary of construction activity standards: • A designated person must be on site during operating hours who is responsible for supervising the use and storage of hazardous materials and who will take appropriate mitigating actions necessary in the event of a fire or spill; • Secondary containment of hazardous materials and refueling areas must be provided; • Access by the public to hazardous materials left on site during non -working hours must be prevented; • Construction vehicles and stationary equipment that are found to be leaking fuel, hydraulic fluid, and/or other hazardous materials must be removed from the site and the APA or repaired in place as soon as possible and may remain on the site in the interim only if leakage is completely contained; • Storage and dispensing of flammable and combustible liquids from tanks, containers, and tank vehicles into the fuel and fluid reservoirs of construction vehicles or stationary equipment must meet Uniform Fire Code requirements; • Equipment and supplies adequate for the immediate clean-up of the worst case hazardous materials spill must be stored on site in close proximity to hazardous materials; and ■ Unauthorized releases must immediately be contained, reported, and cleaned up. 5. 6.7 Fill quality Standards Fill material imported to the City may not contain contaminants that exceed Model Toxics Control Act Cleanup levels. An Imported Fill Source Statement is required for any project in Zone 1 or Zone 1 Modified if more than fifty yards of imported fill will be brought to the site. It is required in Zone 2 if more than 100 yards will be imported. The Development Services Division implements fill quality standards in the APA with the assistance of the Water Utility. A summary of information that must be provided in the fill source statement is provided below: • Source location of imported fill • Previous land uses of the source location 6-8 • Whether or not fill to be imported is native, undisturbed soil • Whether or not the source location appears on government lists of contaminated sites • Results of sampling and analysis of fill to be imported • Whether or not fill meets quality standards A source statement is not required for fill material obtained from a Washington Department of Transportation approved source. Sampling and analysis of fill material is not required if a professional engineer or geologist certifies that the fill source site has never been developed, filled, or used such that contaminants could have entered the soil. Grading permits and other permits allowing imported fill will be issued prior to submittal of the fill source statement. However, the applicant is required to submit the source statement prior to placement of fill. Construction and building inspectors check to see that statements certified by a professional engineer are on file for fill placed at construction sites. 5.6.8 Stormwater Management Requirements The City prohibits stormwater infiltration in Zone 1 of the APA to reduce the risk of infiltration of hazardous materials spills borne by stormwater. Zone 1 is largely commercial and bisected by numerous arterials, a freeway, and a state highway subjecting it to a relatively high risk of hazardous material spills. Stormwater conveyance, detention, and water quality facilities constructed in Zone 1 are subject to specifications that have been adopted to ensure that stormwater is contained within the system prior to discharge to the Cedar River. In Zone 1 Modified and Zone 2, stormwater conveyance and water quality facilities are required to be lined to allow treatment to occur prior to infiltration. There are no other restrictions on infiltration in these two zones. The City has lined major stormwater conveyance pipes nearest to the downtown wells to prevent hazardous material spills from leaking into the aquifer. 5. 6.9 Wastewater Requirements Wastewater collection pipes are subject to pipeline specifications that prevent leakage of sewage into the aquifer. Older wastewater conveyance that was subject to leakage in the vicinity of the downtown wells has been replaced in recent years with pipe that meets current specifications. New on-site sewage disposal systems are not allowed in Zone 1. Existing structures in Zone 1 that are within three hundred and thirty feet of an existing gravity sanitary sewer with capacity have been required to connect to it. On-site sewage systems are allowed in Zone 1 Modified and Zone 2 for single-family residential development if sewer is not considered to be available according to the policies of the Wastewater Utility. 5.6. 10 Secondary Containment of Underground Storage Tanks 6-9 Renton underground storage tank (UST) regulations include spill/overfill protection and monitoring for leaks similar to state regulations but they cover a broader range of USTs. The City includes smaller tanks (down to 60 gallons) and does not exempt some of the tanks exempted by the state (e.g. those that are part of a wastewater treatment facility, tanks containing wastes that are subject to federal solid waste regulations, hydraulic and electrical equipment tanks, emergency back up containment tanks, etc.). City regulations are implemented by the Fire Department and supplement the already extensive regulations related to USTs contained in the Uniform Fire Code. The Fire Department alerts the Department of Ecology should the tank appear to be out of compliance with state regulations. 3.6.11 Pesticide and Fertilizer Risk Management The Wellfield Protection Study concluded that the risk to the aquifer associated with commercial and residential use of pesticide and fertilizer was not a major threat due to limited quantities used. It cautioned against imposing restrictions on the general public that would be difficult and costly to implement. When we have tested for pesticide, none was detected. Accordingly, the City pesticide/fertilizer program primarily relies upon education and information collection. Residents are educated via our Aquifer Awareness Program to minimize use of pesticides and fertilizers. Along with the Local Hazardous Waste Management Program in King County, the Water Utility and the Solid Waste Utility distribute information regarding alternatives The City has adopted regulations that require persons who keep records of pesticide applications per Washington Department of Agriculture rules, usually commercial and institutional applicators, to provide the records to the Water Utility. The purpose of this requirement is to, over time, get a better picture of pesticide and fertilizer use in the APA. 5.7 Coordination with Emergency Responders 5.7.1 Response Procedures Response to hazardous materials spills in well capture zones is the responsibility of the City of Renton Fire Department. The Water Utility's role is to provide information to Fire Department staff about drinking water wells and the aquifer, to respond to selected spills that are of particular concern, and to follow up to ensure that long term remediation, where necessary, is adequate to protect drinking water. The Fire Department has been enthusiastic and professional in its efforts to protect the drinking water supply. The Renton Fire Department's HAZMAT Unit provides first response to any hazardous material spill within the City limits after dispatch by 911. Actions by the first arriving officer include product identification, isolation of the area, and denying entry. The spill is then contained, if possible, by such means as shutting off valves or righting containers. A spill that cannot be contained will be confined to prevent spread into drains and waterways. Plugging and diking drains or using absorbents, barricades, and booms, etc accomplishes confinement. 6-10 The Incident Commander (IC) for spills occurring in Renton is a Fire Department employee according to an agreement with the Washington State Patrol. In particular, the IC is the person -in - charge beginning with the first arriving unit. Command is transferred to ranking officers as the emergency dictates. If the IC determines that the spill will concern other City of Renton agencies, they will request activation of the Emergency Coordination Center (ECC). The ECC, which is headed up by the Fire Chief, has overall control and includes representation from each City department. Assistance in denying public entry to the affected area or in carrying out evacuation orders is provided, as needed, by the Renton Police Department. Assistance in containing a spill that poses a risk of entering storm sewers and/or surface water is often provided by the Maintenance Division of the Planning/Building/Public Works Department. The Fire Department's Hazardous Material Specialist provides technical support to the HAZMAT Unit. This specialist is notified of spills and responds as quickly as possible to the scene to assist with product identification, review of written and on-line technical data relevant to management of the spill, and, in some cases, to run tests on the product to determine it's characteristics and control. The Hazardous Materials Specialist also serves as the City's liaison to county, state and federal agencies that may be brought in to assist with a spill. The IC notifies the Water Utility if the spill occurs inside the Aquifer Protection Area (Figure 6-1). Upon notification of a spill in the APA, Water Utility staff, at their discretion, discuss details of the incident with the IC, respond to the spill in person, and/or contact the responsible party to ensure that appropriate soil and groundwater testing are done. Utility staff will follow up on both short and long-term cleanup activities to ensure that drinking water is protected. If the spill occurs at a facility regulated by the Utility, staff may require, as provided by the Aquifer Protection Code, that the owner file report(s) detailing the reason for the spill, procedural changes to prevent spills in the future, and remediation progress. The Utility may seek the assistance of the Seattle -King County Department of Public Health to assess risk associated with a contamination incident and to communicate with the public if residents or business owners have concerns regarding exposure. The IC notifies the Department of Ecology (Ecology) according to the following general guideline: Should the spill be on land, Ecology will be notified if the quantity exceeds ten gallons. A spill of any size is reported to Ecology if it reaches surface water or has the potential to do so. Ecology will respond at its discretion depending on environmental risk and whether the first responders have the spill under control. The IC may contact the EPA for assistance in responding to either very large spills or very hazardous spills. The Local Emergency Planning Committee of King County (LEPC) may be called out to coordinate response of neighboring emergency responders to respond to large or very hazardous spills. The King County LEPC would coordinate response to a major disaster such as a severe earthquake. LEPC has compiled a database of hazardous materials present at facilities that are required to report their inventory according to federal Superfund Amendments and Reauthorization Act. This information can be used to direct emergency response to those facilities that pose the greatest risk to the public. The LEPC has resources suitable for such response that local fire departments or districts may not have. 6-11 6.7.2 Clean Up Procedures Clean up of the spill can be addressed when the material has been identified and contained. If the shipper of the product or other party responsible for the spill is known and can be contacted, the IC will require them to clean up the spill or contract with an environmental cleanup firm to do so. If this is not possible, HAZMAT may clean up small spills and may attempt to recover costs later. Ecology directs cleanup activities for spills to which they respond, again attempting to get the responsible party to clean up or contract with a cleanup firm. When this is not possible, Ecology has it's own contractor clean up the spill. Costs are rarely recovered in such cases. The Washington State Department of Transportation (WSDOT) responds to spills on state or interstate highways after notification by 911. WSDOT is equipped to clean up small spills and can siphon fuel out of ruptured fuel tanks to prevent further leakage. HAZMAT and fire suppression crews carry plastic laminated maps showing well locations and the Aquifer Protection Area in trucks and command cars. Aquifer protection is taken into account in determining appropriate response to both fires and hazardous materials spills. During a fire, the IC will consider such factors as the degree to which the fire can likely be controlled, the risk to fire fighters, the toxicity and flammability of the materials stored in affected structures, and the proximity of sensitive environmental resources such as groundwater and surface water features when determining whether suppression with water and foam is appropriate. The IC may decide not to extinguish the fire and may only spray adjacent structures to prevent spread of the fire, in which case the likelihood of infiltration of contamination to the aquifer is reduced. Some of the larger and/or higher hazard facilities in well capture zones have drainage control systems. These systems direct both sprinkler and fire suppression water to a watertight pond from which it can be later removed along with any contamination associated with the incident. 6.7.3 interagency Cooperation The Water Utility and Fire Prevention Bureau work cooperatively to collect hazardous materials inventories from facilities located in the Aquifer Protection Area. 6.8 Aquifer Management Monitoring Program In addition to operations and regulatory monitoring, the Water Utility conducts aquifer monitoring designed to provide early warning of contamination moving towards production wells. Appendix 1. of the City of Renton 1996 Water System Plan contains details of the Aquifer Management Monitoring Program. In 2011/12, a risk assessment, priortization and repair and rejuvenation of monitoring wells project is being undertaken. This will produce a cost effective and risk -relevant monitoring program. The goal is to monitor production wells and nearby monitoring wells approximately quarterly for volatile organic chemicals (VOCs). Water level, used to determine the rate and direction of groundwater flow, is usually measured at the same time. Aquifer water quality and water level data, used in conjunction with a computerized groundwater flow model, enable the City to quickly make operational changes that prevent contaminated 6-12 groundwater from entering production wells. Data are also useful in determining the source of contamination. Both water quality and water level data are entered in a computerized database. Most production wells are fitted with water level transducers that measure water levels continuously and automatically transmit data to a computer database. 6.9 Countywide Efforts to Protect Groundwater The City is an active participant with the King County Department of Natural Resources, the Muckleshoot Tribe, state agencies, and citizen groups to protect and manage water resources of the Cedar River Basin. The adopted Cedar River Basin and Nonpoint Action Plan guides this effort. The Water Utility and Stormwater Utility worked to ensure that groundwater protection would be emphasized by this watershed plan in keeping with the City's perspective that protection of surface and groundwater should be an integrated effort. Actions being taken under the auspices of the Plan protect groundwater quality and promote recharge. The basin planning area encompasses approximately the same area as the Cedar Valley Sole Source Aquifer Project Review Area designated by EPA. The Water Utility played a role in development and adoption of groundwater protection policies contained in Countywide Planning Policies for Growth Management and the King County Comprehensive Land Use Plan. The former contains policies that foster groundwater protection throughout King County while the latter focuses upon rural areas only. The Utility also coordinates with the Local Hazardous Waste Management Program in King County to provide technical assistance to businesses regarding best management practices to protect public health and the environment. 6-13 Table 1-1: Chronology of the Development of Renton's Aquifer Protection Program 1983 to 2010 ACTION OR EVENT YEAR Water System Pian recommends Aquifer Protection Program 1983 Tanker truck carrying diesel fuel overturns on I-405 and spills its contents 1983 City Council authorizes Well Field Protection Study 1983 Well Field Protection Study completed by CH2M Hill and recommendations adopted by City Council 1984 Maplewood Golf Course acquired for use as future welt field to provide back up for downtown aquifer 1985 Development of Maplewood supply 1986-1999 Well Field Monitoring Study Completed by CH2M Hill; Includes installation of monitoring wells, provides ground water quality and flow information for the downtown aquifer, estimates interaction with the Cedar River, and 1986-1988 delineates the Aquifer Protection Area; Initiates ongoing early -detection water quality and water level monitoring program Initiation ofground water quality monitoring using a network of monitoring wells 1986 (ongoing) Olympic Pipe Line Company petroleum spill in Maple Valley; City monitors progress of cleanup to ensure no 1986-1993 contamination of downtown wells.

Tetrachloroethane (PCE) is detected in well PW -8 during routine sampling. PCE is later detected in wells, RW -1, RW -2 & RW 3, and PW -9 as well as in groundwater monitoring wells MW -18, MW -19, MW -20, MW -24, MW -31s, MW -40 and MW -42. The contamination is traced to wastewater ponds and waste soil mixing areas located on the Stoneway property next to Cedar River Park. July and August 1998, Stoneway removes waste concrete slurry from 1997 four ponds found to contain PCE contamination. In addition Stoneway removes waste soil stored on site in the waste soil mixing area which was also found to be contaminated with PCE.

This plan was developed concurrent with a monitoring well prioritization and repair project that Pacific Groundwater Group (PGG) is performing for the City. As significant overlap between the two projects exists and the monitoring well prioritiza- tion project continues for an additional year, recommendations in this memo may differ from fi- nal recommendations made in the monitoring well prioritization and repair report. As part of this Aquifer Monitoring Plan update, PGG reviewed the Aquifer Management Moni- toring Plan from the 2005 WSP, interviewed City of Renton personnel involved in aquifer moni- toring programs (Tom Malphrus, Abdoul Gafour, Helen Weagraff, and Craig Pray) to identify potential improvements and goals, and coordinated recommendations to be in line with the rec- ommendations being made for the monitoring well prioritization and repair project. AQUIFER MONITORING PLAN SUMMARY The City maintains 54 monitoring wells to evaluate aquifer water quality, groundwater flow paths, and changes in groundwater levels. The goal of monitoring is to provide an early warning system for contaminants present in Renton water supply aquifers and to track short term (season- al) and long term changes in aquifer water table elevations for the purposes of water resource management. The number of wells may decrease in the future as a result of decommissioning of low priority wells. The City hired PGG to assess the state of the City's monitoring wells and to recommend main- tenance, upgrades, and decommissioning as may be appropriate. The ongoing monitoring priori- tization and repair project includes prioritizing the monitoring wells based on their probability of detecting a contamination event prior to detection in production wells. Depending on final results of the assessment and maintenance recommendations, modifications may be made to the aquifer monitoring plan prior to the next WSP update. The three major components of the plan are explained in the subsections below.

A primary con- straint is that production wells are currently sampled quarterly and monitoring wells are sampled for water quality annually. Those disparate schedules are one factor influencing which monitor- ing wells should be sampled to meet the early -warning objective (as monitoring wells close to production wells are not sampled frequently enough to provide early warning). Although the monitoring well prioritization and repair project is not complete, an interim rec- ommendation is that the City collect annual Volatile Organic Compound (VOC) samples from the 12 monitoring wells listed below. Additional monitoring wells with high priority will be dis- cussed in the final report and may be included in future monitoring events at the City's discre- tion. The proposed annual sampling schedule and wells identified for sampling are listed in the following table, with wells for each sampling event listed in order of priority from highest to lowest. March (six samples) September (six samples) MW -31 S, 31D, 255, 25 D, 4, 34S MW -42, 26, 3, 5, 385, 33 Water Utility Engineering personnel will sample the wells and enter the groundwater quality da- ta into the City water quality database. Detailed sampling plans depend on well and pump configurations which will be determined through the monitoring well prioritization and repair project now underway by the City and PGG. Downtown Aquifer Water Leel Monitoring The goal of water level monitoring in the downtown aquifer is to collect sufficient water level data to allow analysis of short-term, seasonal, and long term trends, including pumping effects, river effects, and effects of urbanization. The proposed program is as follows: Measure depth to water in wells MW -1, MW -10, MW -18, MW -20, MW -21, MW -305, MW -30D, MW -315, MW -31D, MW -34S, MW -34D, OSP-9, HC -6I, MW -25S, MW - 25D, and MW -27. Collect water levels monthly, with a target of bi-weekly measurements from June through August. Measurements should be to a precision of 0.01 feet, referenced to a marked and surveyed measuring point. Elevation survey precision should be 0.01 feet. Renton Aquifer Monitoring Plan 2 FEBRUARY 1, 2012 PgG • Water Utility Engineering Section shall collect these data until determined otherwise, and water level measurements are to be entered in the City water level database. • Use pressure transducers connected to the City's SCADA system and installed in MW -8 and MW -9 to record water levels. Water level data from these wells will be stored in the SCADA System History database. These wells should have periodic manual water level measurements taken to assess transducer drift and so that data are available to correct transducer values in the event that transducer elevations change. Additional recommendations may be proposed in the ongoing monitoring well prioritiza- tion and repair project being performed by PGG, with a final report expected in Novem- ber 2012. Maplewood Aquifer Water Level Monitoring The goal of water level monitoring in the Maplewood aquifer is to collect sufficient water level data to allow analysis of short-term, seasonal, and long term trends, including pumping effects, river effects, and effects of urbanization. The proposed program is as follows: • Measure water levels in the shallow alluvial aquifer and deep Maplewood aquifer at the Maplewood Golf Course. • Use pressure transducers installed in several monitoring wells, including MW -36S, MW - 36D, MW -37S, MW -37D, MW -38S, and MW -38D. Record pressure and temperature every 10 minutes. Periodically download from the transducers and store data on the City's H drive. Water Utility Engineering Section will collect these data until determined otherwise. • As part of the ongoing monitoring well prioritization and repair project being performed by PGG, replacement pressure transducers will likely be purchased due to recurring maintenance and support issues with the existing transducers. wsp aquifer monitoring plan tech memo. doex JE1006 Renton Aquifer Monitoring Plan 3 FEBRUARY 1, 2012 PgG Appendix O WATER FACILITIES INVENTORY FORM ��u],,� WATER FACILITIES INVENTORY (WFI) FORM Quarter: 1 O1 eal t L ONE FORM PER SYSTEM Updated: 12/1512010 Printed: 10110/2011 WFI Printed For: On -Demand Submission Reason: Annual Update RETURN TO: Northwest Regional Office, 20435 72nd Ave S STE 200, Kent, WA, 98032 SYSTEM ID NO. 2.

It presents an overview of the activities that the City has been performing to date, a summary of estimates of authorized water use and distribution system leakage (DSL), and planned activities for further reducing apparent and real water losses within Renton's distribution system. Historical and Current Activities Leak Detection The City began a proactive leak detection program in 1994. In 1999 they purchased leak detection equipment, Subsurface Leak Correlator. They have incorporated leak detection into their routine valve maintenance program. The maintenance crew of two FTEs is assigned to checking all of the valves within the City's distribution system on a regular schedule, which allows them to cycle through the entire system in approximately 14 months. At every valve location, the crew will also use the leak detection equipment to check for any potential leaks. By incorporating the leak detection into the valve maintenance program, the crew is able to check the entire distribution system for possible leaks, on nearly an annual basis. As leaks are discovered they are repaired. Following an aggressive replacement program between 2000 and 2005 for leaking steel pipes, the City has most recently found very few leaks within its system. In order to provide clear documentation for D0H and to facilitate communication with other City departments, it is recommended that the water shop incorporate some specific reporting and evaluation guidelines. 1.) An electronic record should be made for each leak detection testing point of the exact location (nearest meter number and nearest address), date, time, name of personnel performing the test, and the results of the test. 2.) All personnel using the leak detection equipment should be formally trained and certified to use the equipment. Documentation of training should be readily available upon request. 3.) The Subsurface Leak Correlator should be calibrated and maintained regularly per the manufacturer's guidelines. App_P.docx 2,!13112 Appendix P - WATER LOSS CONTROL ACTION PLAN Source Meters All of the City's wells and interties are metered. The well meters are calibrated every two years. Customer Meters Customer meters are categorized as large meters (3 -inches or larger) and small meters (2 -inches and smaller). All large meters are tested and repaired (as needed) on an annual basis. Small meters are repaired and replaced on an as -needed basis. Approximately ten years ago, most meters that were twenty to thirty years of age were replaced. However, at this time there are a number of small meters that are near or past their useful life. The ability of the maintenance department to perform regular maintenance and replacement on its smaller meters is limited by staff size and available budget. The City has replaced all of its large meters and small meters on its two largest commercial meter read routes with radio -read meters. The City is evaluating an expansion of its radio -read meters to include all remaining small meters. It is likely that in addition to improved staff efficiencies, there is a potential for significant benefits by addressing possible meter inaccuracies of aged meters. The maintenance and engineering staff is planning a trial sampling of its oldest small customer meters to quantify possible inaccuracies. Estimated Authorized Uses The following are authorized metered and unmetered water uses that must be subtracted from water produced along with customer consumption to determine the distribution system leakage (DSL). ("Authorized Consumption" is defined by WAC 246-290-820 and WAC 246-290-010.) For each of the estimated authorized uses there is also a description of whether the City is currently estimating this usage. Water Main Flushing The City currently records water used for water main flushing. The maintenance crews have six meters that are used to record water discharged during flushing activities. While this is a good start for documenting all water used for main flushing, there are some recommended changes to the way in which the data is recorded and reported to other City departments that will facilitate reporting to DOH and tracking of water use. It is recommended that the metered water used for main flushing be recorded monthly in its own category, City-Hyd, separate from other water uses. City Maintenance Trucks There are five City maintenance vehicles that use water for maintenance purposes: street cleaning (2), storm vactor truck, sewer vactor truck, and street flusher truck 2 App_i'_dmx 2113/12 Appendix P - WATER LOSS CONTROL ACTION PLAN (used for cleaning muddy streets). Each of these five maintenance trucks have meters on them from which monthly water use readings are recorded. Currently, the water used by these five maintenance vehicles is recorded in utility billing with other water uses. It is recommended that the water use from these five maintenance vehicles be recorded separately from other City water uses. Fire Fighting and Fire Training Both fire fighting and water used for fire training are described as authorized uses that should be subtracted from water production. The City does not currently have any way of estimating the water used for either of these purposes. This could be a significant source of water consumption, particularly for the fire fighting training facility located within the City's service area. Water used for fire fighting is currently unmetered and therefore also not reported. This could at times significantly contribute to apparent DSL. It is recommended that a meter be installed at the fire training facility within the City's service area. This meter would be read as part of the regular meter route for industrial/commercial/institutional customers. For fire fighting, it is recommended that flows be estimated based on the hydrants used and the duration of flow for a specific event. This would require fire department personnel to record information following each event and submit monthly reports to the City's water shop or engineering department. Cleaning Water Tanks and Reservoirs The City does not currently record the water used during the cleaning of its storage facilities because it has not seemed significant since the cleaning is not performed annually. However, since the City is now required to calculate DSL on a rolling three year average and each year meet the DSL requirement there is a potential that in a year where tank cleaning occurs, not recording the amount of water lost during this activity could negatively impact the City's ability to meet it's required goal. Distribution System Leakage Calculation Table 1-I presents the calculation for the distribution system leakage. Included in the table is the past three years (2004 — 2006) of water produced, customer consumption, and estimated authorized consumption. (Nate: for .June 2008 reporting the three-year average will updated to 2005 through 2007.) Renton rarely has to purchase water to supplement its water demands. However, for years that Renton purchases water from the City of Seattle, the amount purchased will be added to the water produced.

Maintenance trucks include street sweeping and vactor trucks. Planned Activities for Reducing Distribution System Losses Five activities or areas of focus have been identified to address apparent and real distribution system losses within Renton's system. These include: ■ Revised reporting of authorized uses ■ Metering for fire training activities and estimates of water use for fire fighting ■ Water audit of City Park's irrigation meters ■ Audit of utility billing system ■ Radio -read program for small customer meters Each of these activities is described in greater detail below, including the reason for selecting each activity. 4 APP_P.docx 2I13i l2 Appendix P - WATER LOSS CONTROL ACTION PLAN Revised Reporting for Authorized Uses Attached to this document are several reporting templates for use by the City's maintenance department. These templates are based on existing reporting templates by the maintenance department, but have been modified to support DOH reporting requirements for the municipal water law. New reports have also been added to record authorized uses, such as tank cleaning that are not currently being measured. Metering for Fire Fighting Activities The City does not currently have any method of estimating the amount of water used for fire fighting activities, which can be a significant contributor to apparent distribution system leaks. Two steps are planned to better be able to estimate water used for fire fighting activities. First, is to install a meter at the fire fighting training facility and begin reading and reporting water use from this facility as part of regular meter reading activities. The second activity is for City maintenance or engineering staff to discuss with the fire department estimating and reporting of fire fighting activities (non -training). A reporting template for the fire department to record water use for fire fighting is attached to this document. It includes the duration of fire fighting activities and number of hydrants used, so that an approximate flow can be calculated. Water Audit of City Park's Irrigation Meters The City's Parks Department irrigation meters have not been systematically inspected to verify the accuracy of the data being recorded. Other large industrial/commercial/institutional (ICI) water users have had meters inspected and in many cases replaced with radio read meters. Other ICI meters are inspected on a regular basis, therefore the Parks Department irrigation meters are one of the next priorities. Audit of the City's Utility Billing System The City's current billing system was installed in 2004. An audit of this system has not yet been performed to fully verify the accuracy of the information recorded and the reporting from the system. It may be that there are inaccuracies with the billing system that are contributing to apparent DSL. It is important to note that there was a significant increase from a long-term downward trend in the calculated DSL between 2004 through 2006, which coincides with the installation of the new software. It is not clear if this may be due to errors that existed in the previous billing system (that contributed to underreporting), or are now occurring with the new system. App P.docx 2AV12 5 Appendix P - WATER LOSS CONTROL ACTION PLAN Radio Read Program for Smaller Customer Meters The City currently has radio read meters for many of its largest customers; primarily ICI. Installation of radio read meters for all of Renton's service area would achieve two objectives. The City will be replacing aged meters that are nearing or have reached their useful lives, and as a result reduce potential under -reading of consumption, which is inherent in aged meters. To date, the maintenance department has not had the staff availability to service and check all of the small customer meters as they have been able to do with the large meters. The second objective that will be achieved with a fully implemented radio read program is reduced staff time to collect meter data and more efficient use of staff resources. Schedule and Budget for Achieving Distribution System Loss Standard Table 2 identifies the planned schedule for implementation of each of the water loss control activities. Implementation of some of the activities, such as estimating water use for cleaning storage facilities and audit of Park irrigation meters, requires less effort and will likely be more easily implemented. Other activities may be more challenging to implement and therefore take longer due to budgetary and/or staff limitations. This is discussed more fully in the last section of this document. Table 3 presents the budget for the planned activities. Most of the activities do not have a budgetary cost associated with them, but in most cases staff time will be required to implement. 6 App_Rducx 2113/12 Appendix P - WATER LOSS CONTROL ACTION PLAN Potential Issues for Consideration Implementation of Water Loss Control Activities There are several issues that could delay implementation of the activities identified in this Water Loss Control Action Plan. Budget Of the five activities identified in this document, the activity that will be most impacted by budget will be the small meter radio read program. Fully implementing radio read meters throughout the City's entire service area will likely require a significant additional budget allocation spanning several years.

App P_docx 2713112 7 Appendix P - WATER LOSS CONTROL ACTION PLAN Staff Availability Implementation of the Park's irrigation meter audit and the utility billing audit will be most strongly impacted by staff availability. For the utility billing audit, it may be that outside assistance will be required, which also could have budgetary implications. The audit also requires cooperation between City departments. Interorganizational 1 Interdepartmental Coordination Several of the water loss control activities will require coordination between departments and groups within the City's governmental organization. Coordination will be required for the irrigation meter audit, audit of the utility billing system, and estimates of fire fighting activities. These additional coordination requirements often can result in a longer implementation schedule and other issues. Additionally, clear documentation and exchange of that documentation between the water shop, and utility billing and engineering is needed to be able to reliably estimate water losses. This is particularly true of the authorized uses that can be subtracted from the total distribution system losses. 8 App_P.docx 2/13/12
