WORTH Li EUGENE U PASADENA :: SACRAMENTO SEATTLE U TUCSON :. WALNUT CREEK WESTWOOD RENTON TREATMENT PLANT ON-SITE EXPANSION PREDESIGN SERVICES SITE- DEVELOPMENT COORDINATION WITH THE CITY OF RENTON The Renton wastewater treatment plant provides secondary treatment of wastewater from southern and eastern King County with disposal of treated effluent to the Green River and disposal of wastewater sludges to the West Point . treatment--plant. The Renton plant is currently operating in excess of its liquid stream design . capacity of 36 million gallons per day (mgd) ; the West Point plant is also operating in. excess of its solids stream design capacity. Facility planning for the Renton . study area was undertaken in 1979 to identify alternatives for expansion of the Renton plant to providefuturetreatmentcapacity. The recommended alternative, approved in 1981 , . consisted -of three major elements : ' 1) construction of new aeration tanks, secondary sedimentation tanks and chlorination facili- ties for a liquid stream capacity of 72 mgd , 2) construction of solids processing facilities for on-site concentration,, stabilization, and dewatering of wastewater sludges. from the 72 mgd liquid stream facili- ties , and 3) construction of an effluent pumping station, tunnel, and outfall for transfer and disposal of treated effluent in Puget Sound. The design of these three elements was divided into two parts : the on-site expansion, consisting of liquid and solids stream processimprovementsandtheoff-site expansion, consisting of the effluent pumping station, tunnel and outfall. Design of the on-site expansion is being done by Brown and Caldwell ; URS Company is designing theoff-site expansion. On-Site Expansion A predesign study for the on-site expansion has identified the improvements needed to increase the liquid stream treatment capacity .to 72 million gallons per day (mgd.) and to process wastewater sludges removed and/or generated during this liquid stream treatment. Follow- ing is a brief description of the proposed major on-site improvements. Liquid Stream. Major liquid stream improvements at the Renton plant include: 1. Construction of a new 'aeration tank. 2. Construction of eight ( 8)._new secondary sedimentation tanks ' and appurtenant pumping systems- and distribution channels. 3. Retrofit of existing secondary sedimentation tanks with new hydraulic controls. 4. Continued use of chlorine: for effluent disinfection and construction of a chlorine building for receiving and storing bulk chlorine in rail tank cars. The subject of chlorine safety was discussed with the City of Renton Fire 2 Chief and Fire Marshall during the predesign study. The new chlorine building will have access control and entry detection devices on all doors and windows as well as safety systems to contain and dispose of any chlorine leaks inside the building. 5. Construction of a second chlorine contact channel . 6. Construction of a septage dilution tank to reduce the strength of septage discharged to the influent and to control odors. Solids Stream. Solids processing facilities will include the following major improvements: 1. Construction of a raw sludge blending/distribution tank. 2. Construction of four ( 4 ) dissolved air flotation thickeners for thickening of combined primary and waste activated sludge. 3. Construction of a thickened sludge blending tank. 4. Construction of four ( 4) anaerobic digesters for stabilization of thickened sludge. 5. Construction of a blending digester for storage of digested sludge prior to dewatering. 6. Construction of a sludge dewatering building for belt filter presses and chemical storage (polymer) . 7. Construction of covered loading facilities for removal of dewatered sludge from the plant site by semi-trailer trucks. ' 8. Construction of a storage tank for belt filter press filtrate. S Other Improvements. Other improvements to be done as part . of the on-site expansion include the following: 1. Construction of a new electrical substation. 2. Installation of a new computerized process control system. 3. Construction of tunnels and roads for access to and maintenance of pipelines, process equipment and tanks. 4. Construction of outside piping systems such as storm drains, tank drains, and air, water and chemical . piping systems. 5. Minor structures and process improvements such as a new prechlorination manhole, an influent flow measuring station, 3 replacement of existing pumps with more efficient models and modifications to the grit and screenings systems. Site Development: for This Enlargement and the Ultimate Plant The number, size, and location of tanks, structures, and equipment required for this enlargement of the Renton plant and for ultimate - development was determined during the on-site predesign study. Table 1 shows the number and size of major process elements at this time, after this enlargement, and at ultimate development. The location of these facilities is shown on Exhibit 1. The ultimate plant layout shown in Exhibit .1 is quite different from that envisioned during the first plant enlargement (1971) , as shown in Exhibit 2. The 1971 layout did not include either on-site . solids processing facilities or a major effluent pumping station. Both the solids processing facilities and the effluent pump station have had a considerable impact on site development. To a lesser degree,, the chlorine building and the septage dumping station have also had an effect on the plant layout. These site development impacts have dictated that the plant make maximum use of the existing plant property and have made it very desirable to acquire additional land. Metro is currently negotiating to purchase the Burlington Northern Railroad property to the south of the existing property as a site for the effluent pumping station, the electrical substation, and the septage access road and for buffer between the chlorine build-. ing and adjacent property. Despite Metro's commitment to purchase additional property, however, several modifications to the existing site will be necessary for construction and efficient operation of liquid stream, and solids stream facilities for• both 'this enlargement and for future enlargements. The proposed modifications must be coordinated with the City of Renton, King County, and adjacent property owners to assure timely completion of the on-site expansion program and to be compatible with the future P-1 drainage. channel and the future Valley Parkway. The required site modifications fall into two categories : 1) dike relocation and drainage, and 2) site access .for sludge hauling trucks. Dike Relocation and Drainage. A large dike was constructed on the north and east sides of the plant as part of the 1971 enlargement. . This dike conformed to what was thought at the time to be the ultimate plant layout (Exhibit 2) . "The presently proposed site layout for this and future expansions will require relocation of the existing dikes on an alignment :corresponding to the new perimeter .road "on the north and east sides of the plant . Exhibit 1) . This will move the existing dike out of the: digester, dewatering building and future secondary sedimentation tank areas. All areas behind the relocated dike where new facilities will be constructed, such as the new digester, the new dewatering building , 3 replacement of existing pumps with more efficient models and modifications to the grit and screenings systems. Site Development for This Enlargement and the Ultimate Plant . The number, size, and location of tanks, structures, and equipment required for this enlargement of the Renton plant and for ultimate development was determined during the on-site predesign study. Table 1 shows the number and size of major process elements at this time, after this enlargement, and at ultimate development. The location of these facilities is shown on Exhibit 1. The ultimate plant layout shown in Exhibit 1 is quite different from that envisioned during the first plant enlargement (1971) , as shown in Exhibit 2. The 1971 layout did not include either on-site solids processing facilities or a major effluent pumping station. Both the solids processing facilities and the effluent pump station have had a considerable impact on site development. To a lesser degree, the chlorine building and the septage dumping station have also had an effect on the plant layout. These site development impacts have dictated that the plant make maximum use of the existing plant property and have made it very desirable to acquire additional land. Metro is currently negotiating to purchase the Burlington Northern Railroad property to the south of the existing property as a site for the effluent pumping station, the electrical substation, and the septage access 'road and for buffer between the chlorine build- ing and adjacent property. Despite Metro's commitment to purchase additional property, however, several modifications to the existing site will be necessary for construction and efficient operation of liquid stream, and solids stream facilities for both this enlargement and for future enlargements. The proposed modifications must be coordinated with the City of Renton, King County, and adjacent property owners to assure timely completion of the on-site expansion program and to be compatible with the future P-1 drainage channel and the future Valley Parkway. The required site modifications fall into two categories: . 1) dike relocation and drainage, and 2) site access for sludge hauling trucks. Dike Relocation and Drainage. A large dike was constructed on the north and east sides of the plant as part of the 1971 enlargement. This dike conformed to what was thought at the time to be the ultimate plant layout (Exhibit 2) . The presently proposed site layout for this and future expansions will require relocation of the existing dikes on an alignment corresponding to the new perimeter road on the north and east sides of the plant Exhibit 1) . This will move the existing dike out of, the digester, dewatering building and future secondary sedimentation tank areas.. All areas behind the relocated dike where new facilities will be constructed, such as the new digester,, the new dewatering building, 4 and the new secondary sedimentation tanks, would be brought up to approximately the same grade as the existing dike as part of this expansion. Areas behind the dike that will see future construction, i.e. , the future digester and future secondary sedimentation tank areas, would be filled under this enlargement to the extent that available soil permitted . Relocation of the dike will remove approximately 27 ,700 cubic yards of floodwater storage volume. A floodwater storage basin would be constructed on the north side of the plant as part of this expansion to compensate for the lost storage volume (refer. to Section _ 1 on Exhibit 1) . The detention basin would be designed to drain to Springbrook Creek as well as the future P-1 channel. As an alternative to the floodwater storage area on the north side of the plant, the lost storage volume would be compensated for by excavating a part of the proposed P-1 channel . Approxi- mately 27 ,700 cubic yards of earth would be excavated from the point where the P-1 channel alignment crosses the Eastside' inter- ceptor to the proposed Southwest 7th Street bridge. All areas to be developed under this plant enlargement will be drained to the existing plant stormwater collection system for dis- charge to the Green River. In addition, provisions will be made for the immediate and ultimate inclusion of all future development. areas into the Green River stormwater collection system. Plant property inside the relocated dike will not contribute any runoff to Spring- brook Creek or the future P-1 channel. For reasons of hydraulic control the dike in the vicinity. of the new and future secondary sedimentation tanks must be construc- _ ted to an elevation matching that of the existing secondary sedi-. mentation tanks. This requirement, combined with space require- ments for the perimeter. road, the chlorine contact channel and the future secondary sedimentation tanks, means that the, relocated, dike on the east will extend beyond the plant property line into the. easement for the P-1 channel (refer to Section 2 on Exhibit 1) . A slope easement will be requested during the permitting process ; how ever, the dike will be designed such that there will be no . infringe- ment on the future P-1 channel or the P-1 channel maintenance road. It, should be noted that the existing dike already extends beyond the Metro property line at the southeast corner of the plant property.. A slope easement was obtained by Metro for that purpose . ) Site Access for Sludge Hauling Trucks. Dewatered sludge will, be hauled from the Renton plant by semi-trailer trucks; the estimated number of trucks leaving the plant is given in, Table 2.. At present the only access to and from the plant is by way of Monster Road. Trucks leaving the plant on Monster Road must travel via Longacres Dr'I've' to' Southwest Grady Way, making a left turn across a busy, unsig- nalized intersection or negotiate ,a narrow overloaded bridge, steep grades and the narrow roadway of Monster Road to the difficult inter- section at Empire Way. . In addition, sludge trucks leaving the plant Table 2.

Operation of dewatering facilities 5 days per week, 8 hours per day. 5 via Monster Road would have to pass through either the center of the plant, past the maintenance and administration areas or directly to Monster Road along the new northern dike. To facilitate sludge hauling and to minimize possible congestion on city streets in the vicinity of Longacres Racetrack it is proposed to construct a new access road at the northeast corner of the plant connecting toSouthwest7thStreet. Haulers will then be able to drive out South- west 7th Street to Powell Avenue, thence right on Powell Avenue to Southwest Grady Way and turn onto Southwest Grady Way at the new signalized intersection at Powell Avenue Southwest. From previous meetings with the City of Renton it has been determined that a bridge would be required over the proposed P-1 channel at this access point. The proposed bridge would incorporate the following design features : 1. Design loading : H2O - S16. 2. Number of lanes : 2. 3. Approximate width between curb faces : 32 feet. 4. Skew angle : 0 degrees. 5. Approximate length : 135 feet. 6. Sidewalk: none. To reduce the centerline grades of the bridge and the entrance road to the dewatering building , the bridge would be designed to provide a minimum clearance of 8 feet over the proposed P-1 channel mainten ance road as shown in Exhibit 3. A ramp around the bridge would be constructed to allow access by high profile maintenance equipment. The Surface Water Management Division of the King County Department of Public, Works has indicated that a ramp is acceptable for their maintenance of the proposed P-1 channel . The intersection of Valley Parkway and Southwest 7th Street would be designed for future left turn lanes as shown in Exhibit •4. The proposed intersection will be coordinated with the. design 'of the east half of the Valley Parkway, to be constructed as part- of the Washington Technical Center. The construction schedule for the Valley Parkway, is not definite at this time. It is assumed that initially only the. Valley Parkway- Southwest 7th Street intersection would be constructed and . that••all sludge trucks leaving the plant would pass straight through 'the intersection on Southwest 7th Street. Since initially there would be no turning movements at the intersection traffic signals would not be necessary. Upon extension of the Valley Parkway to the north- west or to the south a signal would be installed when warranted by traffic volumes. Control of the signal could be by induction loop in the pavement as shown on Exhibit 4. 6 It should be emphasized that the sludge truck access road would be for plant personnel and sludge trucks only. The existing main entrance off Monster Road would continue to be the only access for plant visitors and deliveries.. The centerline alignment of the Valley Parkway after it crosses the proposed P-1 channel is shown leaving Tract "A" of the Washington Technical Center at an unspecified point, crossing Municipality of Metropolitan Seattle property on an unspecified bearing . For proper design of the proposed floodwater storage basin it is requested that the City of Renton provide the Municipality with the final alignment of this section of the Parkway. Construction Schedule The predesign study for the on-site expansion has recommended . a phased contract program to allow liquid and solids stream general contractors to proceed as rapidly as possible. Three design and construction contracts , called Enlargement IIA, Enlargement IIB, and Enlargement IIC, are proposed for this expansion. Enlargement IIA. The Enlargement IIA would include the following items: 1. All excavation work and placement of engineered fill for the new aeration tank, the new secondary sedimentation tanks, and miscellanous channels for the liquid stream facilities. 2. All fill and excavation work for the chlorine building and solids stream .facilities (digesters, thickeners, etc. ) placement of engineered fills and preloads, relocation of earthen dikes to new plant alignments and construction of the bridge and access road to Southwest 7th Street. 3. Relocation of 20-inch diameter high pressure gas main. Enlargement IIB. Enlargement IIB would consist of construction of liquid stream facilities, including the following items : 1. New aeration tank and aeration piping. 2. New secondary sedimentation tanks, distribution channels, and return activated sludge pumping systems. 3. Hydraulic control modifications on the existing secondary . . sedimentation tanks . 4. New chlorine building , including new rail spurs and chlorination equipment. 5. Extension of existing chlorine ,contact channel and construction of part of the parallel chlorine contact channel. 6. Modifications to screenings and degritting systems. 7. Liquid stream area access roads, storm drains, outside piping , site grading , and landscaping . Enlargement IIC. Enlargement IIC would include all solids stream facilities plus modifications related to the liquid stream. 1. Dissolved air flotation thickeners including sludge blending and distribution tanks. 2. Anaerobic digesters and blending digester. 3. Sludge dewatering building and filtrate storage tank. 4. Energy building. 5. Process controls. 6. Septage facility. 7. Influent flow measuring station and secondary bypass flow measuring station. 8. Complete paralleling of existing chlorine contact channel . 9. Retrofit of heating , ventilating and air conditioning systems in existing buildings. 10. Solids stream area access road , tunnels, storm. drains, outside' piping, site grading , and landscaping. As can be seen from Exhibit 5, the design phase of each of -the earthwork and the liquid stream contracts is quite compressed . It is absolutely essential that review of, issues affecting the City of Renton and other organizations be completed in a timely manner if the construction goals are to be met. Previous Discussions with the City of Renton. Documentation of previous discussions. with the City of Renton is provided as an appen- dix to this report. The discussions covered the subjects of dike relocation, drainage , sludge truck access, and chlorine safety. 5 WASHINGTON y IDI X- - TECHNICAL CENTER lit i 21\.; \-1, 1 , '',,, Tk\ -- .

Warren Uhte briefly described the proposed solids processing facilities at the Renton plant and what this will mean in terms of large semi-trailer truck traffic leaving and entering the plant each day. Three alternatives access routes were presented: Alternative A--Connection to Southwest 10th Street Alternative B--Connection to Grady Way Alternative C--Connection to Longacres Drive 2. It was agreed that Alternative A was the best alternative since there will be a signalized intersection at Powell and Grady Way. It was brought out that the Grady Way Bridge has a weight limit of 15 tons, which will prohibit sludge trucks carrying 26 tons of wet sludge from using this bridge. This bridge is scheduled to be renovated within 2 or 3 years according to city personnel. 3. Ron Nelson said that it is very likely there will be a drainage channel as planned. Therefore, a bridge will be required for Alternative A. Files August 23, 1982 Page two 4. The Powell and Grady intersection is being financed in part by property. developers. Nelson believes that if Metro uses this intersection, the developers may want some Metro partici- pation. 5. Desirability of a connection to Monster Road around the north end of the plant is still in the planning stages. Developers to the north are required to make a tie to Empire Way. 6. Puget Power may develop some property along Grady Way; Metro might approach Puget Power about participation in the roadway. 7. Warren Uhte described proposed changes to the existing dikes . Relocation would remove approximately 9. 9 acres from potential use for floodwater storage. There would be sufficient Metro property outside the dikes to compensate for lost storage by excavating approximately 7.4 acres to a depth of 3 feet. It was further expalined that at ultimate development all surface runoff from the plant will be diverted to the Green, River. 8. City personnel saw no problem at this stage, but suggested that Brown and Caldwell provide full documentation when presenting this proposal to the City Council.. 9. Nelson said that if the channel is constructed the 2 foot3 storage volume per 1 foot developed area requirement may not have to be provided. This will be decided by the Director of Public Works or other officials. 10.. Drebin replied that the timing of channel and plant construc- tion may be such that Metro would have to provide the addition- al storage. 11. The city will supply information on bridge standards and development requirements. DH:cp cc: P. Anwar Seattle W.

Healey met with Monaghan to discuss roadway standards for Alternative A, i.e. , roadway cross-section, existing grade at 10th and Powell intersection, width of proposed bridge, etc. 2. Monaghan said that existing roadway at Southwest 10th and Powell as a width of 40 feet face-to-face. Said that city might approve a two phase approach--minimum section now, eventually widened to full width later. 3. Monaghan said that Southwest 10th west of Powell has not been dedicated as a city street; the only present easements are for utilities and access . Southwest 10th will not be extended by the developer if the Valley Parkway is constructed, Monaghan said. 4 . When asked about the Valley Parkway alignment Monaghan referred to a report done by URS showing a proposed alignment approximately 140 east of the centerline of the proposed P-1 ~channel. Proposed centerline elevation at the intersection of .Valley Parkway and Southwest 10th is approximately Elevation 116 (plant datum) . (See attached sheets . ) 5. At this point another engineer with the City of Renton joined the discussion. His opinion of Alternative A was that if it were constructedthe intersection with Valley Parkway would be unsignalized and probably channelized to permit right turns only on and off Valley Parkway. He believed that Alternative A might not be approved by the City of Renton. 6. Considerable time was spent on the pros and cons of this proposed access. Monaghan and the other City of Renton engineer were skeptical about Alternative A. Suggested look- ing carefully at geometrics and at other access routes. Files August 26, 1982 Page two 7. Development schedule of Valley Parkway is uncertain. Property bordering the Valley Parkway is Tract "B" of Washington Tech- nical Park (plat under final review) ; development may be by 1985 at which time Valley Parkway right-of-way would be . . dedicated. Action required: 1. General impression given that Alternative A .would be discouraged by City of Renton Engineering Department. 2. The proposed connection to Southwest 10th should still be considered, but other means of access investigated. Possible option is Southwest 7th Street, which will curve to the southwest, connecting to Valley Parkway near the northeast corner of the plant. 3. Prepare documentation for both access roads (7th Street and 10th) with "no project option" (exit to Monster Road) . 4. Look into acquiring triangular Burlington Northern property to south of plant.

A-1 ii TASK G247 CHLORINE RISK ANALYSIS AND EMERGENCY RESPONSE PLAN The enlargement of the Municipality of Metropolitan Seattle ' s Renton wastewater treatment plant includes conversion of the existing chlorination storage system from multiple one-ton con- tainers to single railroad tank car containers . This conversion requires many other changes, including changing the location of delivery and storage buildings , providing additional capacity for evaporation and metering , and provision of special safety equipment . The City of . Renton' s Fire Department, which is responsible for the safety of the citizens in the area of the treatment plant, wants to ensure that the changes occurring in this system do not increase the risk of chlorine leakage from the plant and , if possible , decrease the probability of a chlorine leak. In addition, the Department requires that an emergency response plan, specific to a chlorine leak at this facility, be prepared . This report presents such a plan specifically and in as much detail as possible. The plan interfaces with the Emergency Response Plans and Interagency Mutual Aid agreements that the City of Renton now has in force . Some new elements involving Metro' s readiness to respond to a chlorine spill and a practical interagency training plan have also been developed . CHLORINE RISK ANALYSIS An analysis of the risk involved in utilizing liquid chlorine delivered to the Renton treatment plant in rail tank cars is pre- sented in this section. The presentation includes the following items: 1. A description of the proposed chlorination system, including safeguards to mitigate potential hazards . 2. A comparison of the relative safety of chlorine delivered in ton cylinders versus rail tank cars. 3. A survey of chlorination installations at other treatment plants. 4. An assessment of the risk associated with rail car deliveries to the Renton site. 2 Proposed Chlorination System The proposed chlorination system includes facilities for receiving rail deliveries of liquid chlorine; for converting liquid chlorine to gaseous chlorine ; for controlling the flow of gaseous chlorine; for injecting gaseous chlorine into water to form a chlorine solution; and for applying the chlorine solution at several locations in the treatment process. The proposed system incorporates safety features designed to mitigate chlorine hazards in an emergency situation. Facilities. Liquid chlorine will be delivered in 90-ton rail cars to a chlorination building located at the southeast corner of the plant, as shown on Figure 1. The industry standard for chlorine delivery containers is the 90-ton rail car. The smaller tonnage cars are being phased out. The chlorination building will be sized to house two 90-ton tank cars , chlorination equipment, and all ancillary systems, as shown on Figure 2. The proposed chlorination facility will have the following components: 1. Rail spur with two sidings, switches and turnouts, locked derails, and railstops. 2. Chlorination building with an approximate area of 3, 600 square feet, including enclosed tank car room. 3. Air padding system with air compressor, aftercooler, receiver, air dryer, air filter and moisture indicator. 4. Unloading platform in tank car• room. 5. Evaporator-chlorinator equipment. 6. Sodium hydroxide absorption tanks. 7. Piping systems including chlorine gas and liquid headers , expansion tanks, and flexible connections . 8. Scales for continuous weighing of tank cars in tank car room. 9. Instrumentation and controls (chlorine detection, feed controls , (etc . ) . 10 . An emergency chlorine removal system. Operation. During normal operation , the chlorine tank car is unloaded by connecting it to the chlorination system with a single flexible coupling . Normally only one tank car will be in the building at any time. When the chlorine supply in the car is nearly 0 \\: NZ00 v., ci:ir,,/i• I •• 4 DEWATERING•. :...;..,\:il i:i:•: 4.: 1.

The full car will be connected and the empty tank car will be taken away. The padding air system is used to purge connecting piping prior to disconnecting the rail car. This prevents any leakage during the connect-disconnect operations. Chlorine is piped from the tank car connection at the unloading platform to chlorine feed equipment located in an evaporator- chlorinator room adjacent to the tank car unloading facilities Figure 2) . Chlorine feed equipment consists of four evaporators and 7 chlorinators. Instrument and control equipment will be located in a separate room. Eyewash and shower stations are located nearby should they be required in an emergency. Chlorine is metered and piped in vacuum piping to the desired point of application in the treatment plant. Neither chlorine gas nor chlorine solution is distributed under pressure anywhere in the Renton plant. The chlorine gas goes into solution in water at the points of appli- cation and this solution is diffused into the wastewater streams. Safety Features. Important safety features of the proposed chlorination system include pressure and leak detection alarms, sodium hydroxide absorption of chlorine from the evaporators, chlorinators , and piping system in case of overpressure malfunction; an automatic emergency chlorine evacuation system; and vacuum dis- tribution piping and fail-safe system shutdown when vacuum fails. The ventilation system of the building is designed to shut down and all louvers close whenever a leak is detected to.provide con- tainment. Sensors that provide information on tank car, pipeline , and evaporator pressures are provided to alarm at the main plant control center. This center is manned at all times. Chlorine lines, tanks, evaporators, and chlorinators have pressure sensitive discs and valves that will allow pressure relief to the sodium hydroxide absorption system in case of equipment malfunction. Leak detection and instrument air solenoids which operate the padding air control valves as well as emergency light, beacon lights, chlorine scales, exit lights, and I/O racks 17 and 17A are on the plant 's emergency generator power supply. Three sensors are provided for detecting chlorine leaks in the tank car and evaporator-chlorinator room. These devices continually sample the atmosphere of these spaces and alarm to the main control center if chlorine is present. When an alarm occurs, the ventilation system is automatically shut down, and an automatic evacuation system is started . This system draws the air/chlorine mixture from the low areas of the bulding through piping to an injection station located on the chlorine contact channel . The system pulls a vacuum in the area where the leak is detected and then injects and diffuses this 4 mixture into the plant effluent chlorine contact channel . This emergency evacuation system will continue to operate until it is shut down manually. The power supply to the pumps that operate the evacuation system is supplied from both main power supplies to the plant. These power supplies are separate, coming from two completely separate substa- tions. This provides a high degree of reliability. In the unlikely event of complete loss of power, the ventilation system and all louvers will close. This is the desired result, since all plant flow would be stopped and evacuation of chlorine to the effluent would not be desirable . Return of the ventilation system to normal must also be accomplished manually. A sump lined with special plastic is located in the railroad tank car room. This sump is designed to contain any liquid chlorine which might escape from the tank car and not evaporate immediately. Chlorine gas is heavier than air and therefore it will settle and concentrate in this sump. The sump is equipped with two evacuation headers and a chlorine leak detector as well as a liquid level detector. Should such a liquid spill occur, the leak detector would shut down the ventilation system and activate the evacuation system described earlier. While in the building, the chlorine rail cars are parked on weighing scales with remote readout and recording so that thequantityofchlorineonhandisknownandcanbedocumentedat all times. Available process chlorinators can be used to evacuate as much as 20 tons per day of chlorine from the tank cars into the various plant waste streams should this become necessary. Ton Cylinders A chlorine ton cylinder is basically a heavy steel cylinder weighing 1, 550 pounds empty and sized to contain 2, 000 pounds of chlorine. The cylinders are fitted with drawoff valves and internal piping as shown in Figure 3. When positioned so that the valves are vertically aligned , chlorine gas may be drawn off the top valve and chlorine liquid off the bottom valve . Each end of the cylinder has 3 fusible plugs. These plugs are designed to relieve pressure should the cylinder be in a fire and the temperature reach 158°F. During shipment , a bolt-on cover in the concave end of the cylinder protects the valves. Maintenance and care of the ton cylinders is the responsibility of the chlorine supplier and is strictly regulated by the Federal Department of Transportation. f )0 i III IIic "'‘‘ \ T T 1 I 0 c14\‘‘\ — //// 19 S,..,,,&„io t I I TYPICAL TON CYLINDER CONNECTED FOR GAS I FUSIBLE I 1.01 PLUG TON CYLINDER CUT-AWAY Figure 3 Chlorine Ton Container 5 Rail Tank Cars Railroad tank cars for transport and delivery of chlorine are specifically designed and manufactured for this purpose only. A typical rail car is shown in Figure 4. The shell consists of 13/16-inch to 1-1/4-inch steel with a 4- to 6-inch cork insulation covering and another steel outer shell . The cork insulation prevents heating of the tank contents . The only opening in the tank is in the dome which has a bolt-down steel cap. Newer tank cars have special couplings and head shields that make puncture of the tank highly unlikely. These rail cars are serviced each time they are returned to the supplier as follows : 1. Any chlorine gas remaining in a tank car is purged and sent to the chlorine disposal system. 2. All four angle valves are removed and sent to the valve reconditioning shop. 3. The tank interior is carefully inspected , by use of an approved low voltage drop light, for signs of any foreign material . 4. Fully reconditioned valves are installed on the car. These valves have been disassembled and their parts and threads inspected by careful , experienced workmen. Valve stems are ground into the seats and the stem threads are lubricated with graphite. Valves are reassembled with new valve packing and are tested at 500 pounds pressure . 5. At least every two years , ever tank car in the fleet is washed , pressure-tested , and dried . At this time , cover plate gaskets and safety valves are renewed . Comparison of Ton Cylinder and Tank Car Safety The relative safety of ton cylinders and rail tank cars for transport, storage , and use of chlorine at the Renton treatment plant is described below. Transport. Transport of chlorine ton cylinders to Renton is accomplished by special semi-trailer trucks capable of handling up to 12 one-ton containers . Accidents during delivery of ton containers , whether by motor vehicles or rail cars , are rare. Forty years of accident records of the Chlorine Institute do not list any instances of chlorine emissions from ton cylinders during delivery. The U.S. Department of Energya analyzed the risk involved in transporting liquid a" An Assessment of the Risk of Transporting Liquid Chlorine by Rail , " by W. B. Andrews .

The analysis indicates that one accident per year nationwide can be expected , which results in at least one death. The only serious chlorine emission accidents with tank car deliveries of chlorine have occurred in rail accidents during long haul transport situations. The two worst accidents resulted from tank car ruptures which occurred during a massive derailment in a long freight train. The ruptures were the result of the coupler on a trailing car that became separated , and the momentum allowed the coupler to punch a hole in the end of the chlorine tank car. Other emission accidents caused by derailments have resulted in the loss of all valves in the car dome. These emissions have been minor owing to safety check valves in the car's liquid lines which prevent the loss of liquid chlorine. Safety teams are dispatched with emergency kits that seal off any gas emissions from the dome assembly. Newer tank car models are equipped with shelf couplers and head shields which minimize the possibility of tank car rupture during a derailment.a . Presently, one to four chlorine tank cars pass through Tukwila and Renton past Longacres and Southcenter on a daily basis, trans- porting chlorine from the Tacoma and Bellingham production facili- ties to users throughout the Pacific Northwest. The quantities of chlorine transported to Renton will represent less than 5 percent of the total chlorine transported through this area on a monthly basis. There have been no reported tank car accidents in the State of Washington involving chlorine emissions . Therefore, it can be reasonably concluded that there is a minimum hazard of chlorine release occurring during tank car or ton cylinder delivery. Storage. Storage of ton chlorine cylinders can be a hazard . Ton cylinders in storage have caused more serious chlorine emissions than any other type of container storage system, including small swimming pool and water supply containers ( 100 and 150 pound ) , tank cars , and bulk storage tanks. There is a technical reason for this. As shown in Figure 3 , each ton container has two outlet valves : one for liquid chlorine and one for chlorine vapor. These two valves are potential sources of a continuous leak. Each ton container also has a total of six fusible plugs--three in each of two "dished" heads. Each of these fusible plugs is subject to chlorine leakage caused by an elevated ambient temperature (solar radiation at 150°F) or a nearby fire , or by metal fatigue due to the age of the fusible plug . In addition, each ton cylinder requires a flexible connection, which by their very nature are vulnerable to deterioration and leakage . Recently, a fusible plug failed at the City of Seattle Water Department 's Landsburg site, resulting in a release of chlorine . Fortunately no people were hurt. a Excerpted from "Safety Analysis of Feasible Alternatives, " by George C. White, Appendix 2, Predesign Subtask Bl 7 Storage of large amounts of chlorine is safest in a rail car, and there are obvious reasons for this. As shown in Figure 4, a rail car has 4 to 6 inches of cork insulation which prevents wide swings in vapor pressure due to ambient temperature changes even when stored on an open siding with no protection from solar heating . A rail car has a dome assembly that is well protected by a heavy steel cover. In this dome there are two vapor outlet valves, two liquid outlet valves, and one pressure relief valve. The liquid outlet pipes inside the tank car are equipped with safety check valves , upstream from their outlet valves. These check valves jam shut in the event the liquid line is broken or there is a sudden flow due to a liquid leak. In the event of any valve malfunction in the dome, an emergency kit can be applied by operating personnel to stop a leak in a matter of 10 to 15 minutes. A rail car has one flexible connection for transferring the tank contents. Such flexible connections in any chlorine system are the most vulnerable parts , and this is where most of the chlorine emissions occur, whether it be 150-pound cylinders , ton containers, or tank cars . Each single connection of a rail car represents 90 connections of one-ton cylinders. Thus , the chances for leakage occurring during connection operations are much less with rail cars . One of the most important safety considerations in a rail car operation (generally overlooked) is the ease with which a rail car in trouble can be moved out of the area. Experience has shown that emissions from defective valves have gone completely unnoticed when the car is kept moving . This phenomenon was discovered when a 32-ton car left the chlorine plant in Niagara Falls, New York, one evening at about 6 p.m. and arrived at its destination some 250 miles later almost completely empty. A detailed investigation of the foliage along the route showed little evidence of any chlorine emission. The investigators did not find anyone living adjacent to the rail route who detected any odor of chlorine . Use. Chlorine evaporation, piping , and metering systems are the same, whether ton cylinders or rail car storage is used . The difference in risks of using ton containers versus rail cars boils down to the characteristics of the containers and their connection to the system. Most of the comparisons mentioned in the storage section are applicable to use. Ton container emergency kits are effective in the event of a leaky cylinder valve or a fusible plug failure . If more than one cylinder is involved in a leak situation, it becomes increasingly difficult to contain due to the need for multiple emergency kits and the availability of adequately trained personnel to handle such emergencies. Each ton container requires a flexible connection to the system manifold . Failure of these connections due to continuous use and internal corrosion is a common source of accidental chlorine emissions from ton cylinders . 8 Ton cylinders are unusually tough and rugged containers. However, they do have an inherent structural weakness that can result in a massive leak, albeit this would be a rare occurrence. A leak may occur at the rim joint where the "dished" ends of the ton cylinder join the main cylinder. While failure at this joint is rare, such a failure usually results in the total loss of the contents of the ton cylinder. Emergency kits are ineffective for this type of leak. There are fewer hazards with the use of rail cars than with ton containers. First, there is only one flexible connection. Secondly, there is only one specific area where a leak will occur, and this reduces the time to locate the leak in the event of an emergency. Thirdly, a broken liquid supply line is quickly shut off by the rail car' s emergency liquid check valves. Finally, no fusible plugs are used on rail cars , whereas each ton cylinder has six. Results of Comparison. The above comparison illustrates that tank cars are a safer means of handling bulk chlorine deliveries at the Renton plant than are ton cylinders. The main reasons for this are the lack of fusible plugs and superior safety features on rail tank cars , as cited above , as well as the use of a single flexible connection for transferring the tank car contents . Use of ton cylinders requires multiple connections and thus there is a greater opportunity for leaks. Table 1. . Potential for Leaks--Comparison of Ton Cylinder versus 90-ton Rail .

Survey results are presented in this subsection. Sacramento County, California. Sacramento County, California uses several specially trained emergency teams at several locations throughout the county to respond to chlorine leaks at county facili- ties. Training includes instruction for repair of leaking cylinders and tank car installations , for use of protective suits , on different types of valves and other equipment, and on practical training in responding to leaks. Class instruction was developed by the county to develop teams which could handle leaks at any location, regardless of the size of chlorine cylinder, type of valuing , or make of equip- ment. Eight hours of training are given initially, with refresher classes offered at two-month intervals. The County has used rail car chlorine storage at its Central and City Main Plants for many years . Training is carried out with both ton cylinders and tank car domes under pressurized (nitrogen or compressed air) conditions. The new Sacramento Regional Treatment Plant has dual spur tracks for handling 90-ton tank cars. Oakland , California. The East Bay Municipal Utility District EBMUD) operates a modern secondary treatment facility at Oakland , California utilizing oxygen activated sludge . Originally built in 1951 to provide primary treatment, the plant was upgraded in 1978 to provide full secondary treatment up to 168 million gallons per day mgd ) . Average daily flow is currently 73 mgd and peak dry weather flow is 100 mgd . The chlorine unloading station at this facility is a fenced enclosure with a spur track for tank cars on each side of an unloading platform. A 45-ton capacity storage tank rests on a balance scale beneath the unloading platform. The platform has connections for liquid chlorine transfer lines. Air-operated valves automatically shut off liquid chlorine in the event of a pressure drop. There are bottles of nitrogen, as well as dry air piping , at the platform for purging chlorine pipelines. Pipelines from the chlorine unloading station to a chlorination room are , for the most part, contained in a concrete pipe trench. One section of the pipelines is buried under a roadway. At the chlorination room, the liquid chlorine is vaporized to gas in electrically heated water bath evaporators. The gas is reduced in pressure and fed through chlorinators and injectors for application to wastewater streams. All chlorine evaporators and chlorinators, and some injectors , are located in the chlorination room. Other injectors are located 10 near the point of chlorine use. Chlorine gas under vacuum is piped to these locations. Average annual chlorine consumption is about 6. 6 tons per day. Over half of this amount is used for odor control of the influent wastewater. A 1980 study of alternative disinfection and odor control techniques at the Oakland plant recommended continued use of chlorine with the following modifications to improve security, safety, and operation: 1. Improvements to the chlorine leak detector. 2. Alarm system modifications and improvements. 3. Additional seismic restraint of the chlorine storage tank, and replacement of the tank dome. 4. Piping and structural modifications to the chlorine unloading tower. 5. Addition of personnel exit doors with panic hardware to the fence around the chlorine unloading area , and installation of an emergency shower and eyewash. 6. Piping , ventilation, and other miscellaneous changes in the chlorination room, including replacement of expansion tanks. 7. Extension of, the chlorine pipe trench, ventilation and drainage of the trench, conversion of an existing liquid chlorine line to a vapor relief line , and replacement of some of the existing piping. These improvements have recently been made at the EBMUD plant. The continued use of chlorine at this facility was based on a chlorine risk ' analysis which stated : The elimination of chlorine at the EBMUD treatment plant would have an insignificant effect on the chlorine risk to the public , due to the amount of chlorine used for industrial purposes in the area, the amount of chlorine shipped through the Port of Oakland and the Army and Navy Depots, and the large amount of chlorine shipped by rail through the area. The Dow chlorine plant ships a major part of its production to users located to the south of its Pittsburg facility, much of it through the EBMUD service area adjacent to the plant. " San Jose, California. At the San Jose/Santa Clara Water Pollution Control Plant, about 11 tons of chlorine are used daily. Liquid chlorine is received in 90-ton rail cars , and there are provisions for unloading from two chlorine rail cars. Liquid chlorine is piped from a rail car to five evaporators where it is 11 vaporized to a gas. The gas is metered in chlorinators under a vacuum and injected into a water solution. The solution is then , diffused into and mixed with the wastewater. As much as 270 tons of liquid chlorine in 90-ton tank cars could be located at the plant at any time. The liquid chlorine pipelines hold about 1,200 pounds and the five evaporators can contain as much as 1,000 pounds. There is an Operation and Maintenance Manual , an Emergency Training Program, and an Emergency Evacuation Plan for plant staff. There is excellent safety awareness on the part of management and staff. Emergency training activities include instruction for: 1) life support and decontamination; ( 2) tank car repair; ( 3) tank car hookup; (4 ) leak containment; and ( 5) team response procedures. The plant has a 9-page , printed Emergency Evacuation Plan for chlorine leaks at the tank car storage area. This document provides an excellent approach to helping employees escape from a reported chlorine leak. Chlorine hazard potential was assessed at the San Jose plant using dispersion models to estimate the effects of a spill from the tank car berthing area . The berthing area has no containment facilities of the type proposed at Renton. Under these conditions , and depending on the type of spills, rate of chlorine emission , prevailing winds, and atmospheric stability, the area affected by concentrations considered to be dangerous ( 35 parts per million) varied. Highest concentrations occurred over the widest area during stable atmospheric conditions and low wind velocities . Yonkers, New York. The Yonkers, New York sewage treatment plant is designed to process an annual average flow of 92 mgd . Liquid chlorine is delivered in rail rank cars which are housed in a building on site. Because the neighborhood is subject to vandalism, 24-hour security guards are provided through a contract operation. Risk Assessment of Chlorine Transport by Rail The risk of transporting liquid chlorine by rail was analyzed in a 1980 study prepared for the U.S. Department of Energya for estimated chlorine shipping levels in 1985. The analysis indicates that one accident per year nationwide can be expected , which results in at least one death . One accident every 17 years can be expected nationwide which results in at least 10 fatalities. a" An Assessment of the Risk of Transporting Liquid Chlorine by Rail , " by W. B. Andrews. Prepared for U.S. Department of Energy by Battelle Memorial Institute , March 1980. 12 The individual risk of fatalities from chlorine rail car accidents is very low compared to the risk associated with other activities. For example, based on the Department of Energy study, the annual risk of a fatality from a motor vehicle accident is one in 4,000 , and that from fires is one in 32,000. The annual risk of a fatality from a chlorine rail car accident is, on the other hand , one in about 22 million. Of 16 activities examined in the study, only the risk of a fatality from an airplane crash to a person on the ground was less than that from a chlorine rail car accident. Sensitivity studies were performed as part of the Department of Energy analysis to determine the most important contributors to the risk. It was found that tank shell failures due to impact accidents produce over 90 percent of the chlorine transportation risk. Three possible design changes to reduce risk from chlorine releases in tank car accidents were investigated. The first method involved making the tank 10 times more resistant to impact failures. This reduced the expected number of fatalities to 4. 3 per year. The second method postulated the addition of head shields to improve head puncture resistance. Shields conforming to requirements in 49 CFR 179.100-23 are predicted to reduce risk by 4 percent. The third method postulated was replacing existing pressure relief valves with a higher capacity model to prevent over-pressurization during overturn fire accidents. This design change had no observable effect on risk. Conclusion This assessment shows that the risk associated with transport , storage , and use of chlorine delivered to the Renton treatment plant in rail tank cars is minimal . When all factors are considered , the risk with rail tank car deliveries is less than with alternative means of chlorine handling , such as ton cylinders. Safety features have been incorporated into the proposed chlorination system at the Renton site to protect individuals both on-site and off-site , in the event of a chlorine spill. These safety features include an enclosed building to house rail cars and minimize the risk of vandalism, and a detection system to monitor for leaks and instigate automatic isolation and the evacuation and absorption of the leaking chlorine . The training and emergency response by plant and local public service personnel is expected to be the same whether one ton cylinders or rail cars were used. The potential for a major leak, with a large cloud of chlorine at high concentrations escaping from the Renton plant, has been minimized by the building enclosure and isolation-evacuation system, even in the highly unlikely event of tank car rupture . Chlorine escape from the building under a negative pressure would be slowed significantly, and dissipation and dilution would minimize the extent of damage and decrease the distance from the source that damage would be incurred . 13 EMERGENCY RESPONSE PLAN An appropriate Emergency Response Plan to be put into effect in the event of a major chlorine leak at the Municipality of Metro- politan Seattle 's Renton wastewater treatment plant should dovetail with existing local agency Emergency Response Plans, yet be specific to the chlorine emergency. In preparing this Emergency Response Plan, every attempt has been made to incorporate existing plans and encourage the development of specific procedures to be put into action by local agencies in case of a major chlorine leak. The Emergency Response Plan is presented herein as specifically as possible and includes the following items : 1. Chlorine leak detection. 2. Response to leak detection. 3. Estimation of leak quantity and severity. 4. Response to small leaks. 5. Response to major leaks : a. Information b. Notification-communications c. Plant staff response d. Response of local agencies 6. Plan maintenance In order to keep this Emergency Response Plan in perspective , it is necessary to understand that the potential for a major leak of chlorine , with a large cloud of gas at high concentrations escaping from the Renton plant, is extremely small due to the precautions taken, with a building enclosure and an automatic isolation-evacuation system for the building . Even in the highly unlikely event of a rail tank car rupture , the building enclosure and evacuation system would contain the major portion of chlorine gas and escape of gas would be slowed significantly. Dissipation and dilution would minimize the extent of damage and distance from the source where damage would be incurred . Chlorine Leak Detection Three chlorine leak detectors have been provided . They are located near the tank car room sump, at the working area in the tank car room, and in the chlorinator-evaporator room. Detectors operate continuously and are activated at one part per million of chlorine in the room or sump atmosphere. Chlorine detection is indicated by a light and buzzer in the main plant control center , which is continuously manned. 14 Response to Leak Detection When a chlorine leak is detected , the chlorine building powered ventilation system is automatically shut down, louvers are closed , and the chlorine building atmosphere evacuation system starts. This evacuation system draws the atmosphere of the building into a negative pressure condition, sucks the chlorine gas out of the building, and injects it along with the building air into the plant effluent. The person on duty in the main plant control center is instructed to: 1. Notify all plant personnel to clear the area within a 520-foot perimeter around the chlorine facility. Check chlorine weigh scale chart recorder in main control to ascertain leak magnitude. 2. Activate in-plant Emergency Response Crew members on shift to investigate the leak. Crew members will use full pro- tective clothing , self-contained breathing apparatus , and two-way radios, and notify plant control center of severity of leak. A MINOR leak is indicated if the weight recorder shows no significant increase in rate of weight loss for the rail car. Normal weight loss will range from 1-2 pounds per minute. A MAJOR leak is indicated by any weight loss greater than 3 pounds per minute. If leak is MAJOR, go to major leak response directions. Response to Small Leak If the leak is small , locate it using aqueous ammonia solution. Isolate and repair the leak. Ascertain repair by clearing of atmospheric leak detector and shut down emergency evacuation system. Notify main plant control center of. repair. Response to Major Leak If the plant control center and response team determine that a major leak has occurred , the following steps are taken: 1. Notify the Renton Fire Department as the lead agency for emergency response. 2. Check wind direction and speed at the plant control center. 3. Check chlorine scale; determine quantity lost and quantity remaining , and rate of leak. 15 4. All plant personnel not on emergency team are removed from the area by using the emergency code call. 5. Dispatch all remaining emergency response personnel in the plant to the chlorine building. 6. Notify, in order given, the agencies listed below, giving the following details: Renton Police Department: 911 Jones Chemical : 1-572-9030 1-838-0644 East Division Manager: 821-1904 Hooker Chemical: 1-383-2661 Pennwalt Chemical: 1-838-0370 a.

Man the plant entrances if possible to prevent unauthorized entry and to permit emergency crews immediate access . 2. Set up evaporators and chlorinators in plant to feed maximum rate of chlorine from the leaking container into the pre- chlorination and postchlorination systems. 3. Monitor communications system. Remain at the plant control center if possible. If not, relocate upwind of the Chlorine Building with a portable radio unit and maintain communica- tions and command of the plant Emergency Response Team until Hazardous Substances Control Units from the City of Renton arrive and establish a field command post. Once the City' s control units arrive , they are in charge of all activities relating to the spill . Response of Local Agencies. The Renton plant is located in the city limits of Renton, and therefore the City of Renton is the logical lead agency responsible for responding to a chlorine spill . Contacts with all other supporting agencies would be made by the Renton Fire Department Emergency Coordinator. The command post should be at the City of Renton communications center, field command at the Renton plant. The sequence of actions should be as follows : 1. Record information provided by the Renton plant operations : Time of spill Quantity of spill Control actions taken at plant (STATUS) Wind direction Wind velocity 2. Apply data to map (Figure 5) to ascertain chlorine gas cloud direction of travel . 3. Use this information to determine direction of approach to plant for emergency teams and evacuation and traffic control needs. 4. Dispatch Emergency Response Team to Renton treatment plant, giving specific directions on how to approach the plant. Aid cars and all available Hazardous Materials Team members from Renton, Tukwila, Auburn, Kent, Federal Way, and the Port of Seattle should be dispatched . 5. Notify and request specific assistance from the following agencies , as the situation requires: Washington State Patrol: Roadblock interstate and state highways entering hazardous areas. 17 Renton Police : Roadblock entry to city streets in hazardous area and direct evacuation. Tukwila Police : Roadblock entry to city limits in hazardous areas and direct evacuation. Seattle Police: Roadblock entry to hazardous area and assist with evacuation . King County Police: Roadblock county roads entering hazardous area and assist with evacuation. Railroad traffic control in Seattle , Tacoma, Renton, Kent: Prevent rail traffic entry to affected area . 6. Use the Emergency Broadcast System to notify people in the affected area of evacuation procedures. Give specific directions to higher ground or safe areas. 7. Use car-mounted loudspeakers in the Renton and Duwamish River areas to notify people of evacuation need . 8. If the Longacres Race Track or Southcenter Shopping Area will be affected , notify the managers of these facilities of the situation and implement a preplanned evacuation plan to • the south and west. Plan Maintenance A routine training plan is necessary if emergency response is to be effective . Each of the agencies including Metro should routinely practice emergency procedures that are applicable to their particular areas of responsibility. These routines should be continued and in the case of Metro Renton revised and modified to reflect the new chlorine installation .

Schedule of Training Emergency Response Team members at the plant practice response to a chlorine leak once every 3 months . An annual training day is scheduled for knowledge and hands-on training . The classroom training outline is presented here . 19 CLASSROOM PLAN OUTLINE Chlorine Response Procedure Lesson #1 : Properties of Chlorine and Sulfur Dioxide Lesson #2 : Safety Equipment and First Aid Lesson #3 : Chlorine Handling Procedures Ton Cylinder Description and Repair Kit Tank Car Description and Repair Kit C Supervisor's Duties Leak Repair Crew' s Duties Plant Personnel Duties Summary of Steps for Using Scott-Air Pack Emergency Outside Assistance Full-Scale Chlorine Leak Emergency Response Practice It is recommended that a full-scale practice response to a • major chlorine spill at Renton involving all agencies be conducted at least once per year. The individual responsible for setting up the simulated spill will be the Eastside Division Manager for Metro. The practice session should be staged as near to a real emergency as possible , and all agencies should perform their assigned roles as if the emergency really existed according to the Emergency Response Plan. Metro will construct a facsimile with test facilities for chlorine tank car, on-site SO2 storage tank, and SO2 ton storage tank. • Full-size facsimile units shall be designed to be pressurized with CO2, N, or just compressed air with some type of fogging material to simulate as close as possible the action of a real chlorine or SO2 leak. Metro will provide the City of Renton with a Type C repair kit and training which will incorporate cooperative drills with plant and city employees. The East Divi- sion Manager for Metro shall be responsible for provision of the repair kit and continuing coordination of regular training-practice. exercises . APPENDIX A DETERMINATION OF AREA AFFECTED BY MAJOR LEAK This appendix presents the techniques to be used in case of a major leak to predict where the chlorine gas will go and to what extent damage and/or loss of life could be expected . The worst case scenario would be a major rupture of a 90-ton tank car outside of the building. Chlorine would be released at a rate of 7,000 gallons per hour ,a resulting in fatal concentrations for 1,500 feet downwind and a height of 560 feet. Included in this appendix is a map of the area around the Renton plant showing one-mile and two-mile radiuses. The areas which would most likely be affected are shown Figure A) . These areas are shown based on the prevailing wind patterns in the area, according to the wind roses provided later in this appendix (Figures B and C) . Procedure 1. Obtain wind direction and velocity from Metro Plant Operating Supervisor. This information is continually recorded at the plant control building. 2. Obtain leak quantity and duration information. 3. Plot projected gas cloud path using a 20-degree dispersion and assume a rise of 20 degrees. At 4,000 feet out the cloud will be 1,500 feet high. 4. The speed of the cloud movement is irrelevant since the area that is critical to life will be covered in less than 3 minutes even with a 5 mph wind . 5. Order' emergency help to upwind plant entrance. 6. Order evacuations downwind in an area 1. 3 miles wide and 2 miles long.b 1 aSeattle Fire Department, "The Transportation of Hazardous Materials by Rail in the City Waterfront.

Nelson, Building Official FROM:Roger.Blaylock, Zoning Administrator,, SUBJECT: INDUSTRIAL REVENUE BOND FINANCING FOR SLUDGE MANAGEMENT, INC. I attended the King County Economic Enterprise Corporation meeting on Thursday, October 10, to review proposed industrial revenue bond financing of $23 million for Sludge Management, Inc. METRO issued a request for private enterprise to provide alternative ways of treating sludge from the sewage treatment plant. Ten proposals were received and METRO recently shortlisted the project to five. This is the only private enterprise proposing using industrial revenue bonds for the financing of the project. The facility would be operational sometime between July of 1987 and July of 1989, whichever operator was finally chosen. The operation would reduce the necessary area envisioned by METRO for future sedimentation ponds and probably resulted in a net savings to the local consumer. In the meeting, I informed them that they must comply with the City of Renton land use policies and it was questionable at this time whether private enterprise could go into a public zone. Some amendments to the zoning code might occur or an interpretation that since it was quasi-public it was within the realm of the public zone. King County Economic Enterprise Corporation went ahead to issue the inducement document which then allows respective financial organizations to consider the proposal. Nothing is finalized until the City has agreed to issue the bonds and complies with the land use requirements of the City code. I did raise the question of whether the project, since it would be private and under private ownership, would pay taxes and what associated land use problems might result as a consequence of foreclosure of the bond holders of a private enterprise on public property. Those questions the committee will investigate a little further. RJB:ss 1992Z OF R BUILDING & ZONING DEPARTMENT o RONALD G. NELSON - DIRECTOR 09 co MUNICIPAL BUILDING 200 MILL AVE. SO.

Blaylock, Zoning Administrator SUBJECT: Puget Power Substation/S.W. Grady Way Pursuant to our telephone conversation of today, it is my position that the cleanup and relocation of a drainage ditch surrounding the Grady Way Substation site is actually part of the proposed plans for the improvement of S.W. Grady Way. However, as a result of timing, Puget Power wishes to do the.work for the City of Renton prior to the City actually beginning the construction on Grady Way at this specific location. Under the Shorelines Permit, the activity for the improvement of Grady Way had to begin with two years and completed within five. It does not really limit the individual doing the work. Therefore, it is our belief that Puget Power is working under the scope and intent of the City's permit for Grady Way. Our department will not take any enforcement action if we see activity going on in that area, however, we would like to be advised of the approximately time schedule the work will be done in. jmEP1%o Municipality of Metropolitan Seattle ExchangeBldg. • 8Zi SecondAve.,Seattle,Washington 98104 - -- March 12 , 1985 MAR 1' 4 1985 Mr. Ronald Nelsen , Director Building and Zoning Department City of Renton Municipal Building 200 Mill Avenue South Renton , Washington, 98055 Monster Road Realignment by Metro Dear Mr. Nelson: Metro has been given general approval by the Public Work Department of the preliminary plan and profile for the realign- ment of Monster Road adjacent to the Renton Treatment Plant. In accordance with condition #7 and page 5, paragraph 15 , of conditional use permit METRO: CU-007-83, Metro will dedicate approximately 50% of the 60 ' right-of-way and provide a 24 ' wide , 2" Class B asphalt roadway with improved drainage within the 30 ' right-of-way to connect Monster Road with Longacres Drive. We are planning to begin negotiations with the neighboring property owner to secure a small portion of right-of-way on the northwest end of the realignment.

Hanson : The purpose of this letter is to respond to the City of Renton staff request concerning Metro ' s plans for implementing the eight (8) conditions outlined beginning on Page 7 of the City 's conditional use permit No . METRO: CU-007-83 . The City has requested this information in conjunction with Metro 's applica- tion for a building permit for the Renton Treatment Plant Enlargement IIB - Liquid Stream. This letter is also a follow-on to our letter of June 6 , 1983 (attached) , and our responses to the hearing examiner at the hearing of June 28 , 1983 documented on Page 3 of the conditional use permit . y To refresh your memory, the conditional use permit was issued in regard to the . $123 million Renton Treatment Plant Enlargement project which is a phased 'construction program composed of the following contracts : Start Completion Phase Date Date IIA - Site Preparation May 1983 Sept . 1984 IIB - Liquid Stream Enlargement Sept . 1983 Jan . 1986 IIC - Solids Stream July 1984 June 1987 IID - Computer Automation May 1984 • June 1987 IIE - Plantwide Landscaping Spring 1986 Sept . 1987 of 143.K011 A.:‘ ri,'',., a‘,.' t"`r "r CN;r1F.':,te E;aKt,'S'.'47`a,C.,92'`.'1a ',:..; . n a jb,}a tsar a. z;. V r le r o Mr . Jim Hanson City of Renton September 27 , 1983 Page Two This project is a joint effort by the State Department of Ecology and Metro and the funding has been secured . Because of the fast-track nature of this project it has been Metro 's intent to implement most of the City 's conditions during construction of the IIC - Solids Handling facilities . This was previously discussed with City building and public works officials and outlined in our June 6th letter with no objection previously raised by the City . The following is the status of our efforts to implement the eight (8) conditions outlined in the conditional use permit : Condition #1 : The applicant provide affirmation that the Metro Council will permit Metro to participate in an LID which may be created to construct , improve or build the Valley Parkway Oaksdale Road ) . Response : As stated by our June 6th letter , Metro has no ojec- tion to possible participation in an LID to extend S.W. 7th Street to the intersection of the future Valley Parkway and then northerly and westerly over the P-1 Channel to 400 + feet beyond intersecting Monster Road . It has been Metro 's frequent practice in other- locations to cooperate in the LID process as long as the ultimate cost obligation to Metro is equitable. We are presently exploring what action must be taken by the Metro Council to comply with this condition since the City has not filed a petition . We will coordinate with the City in this regard . Condition #2 : Metro shall be responsible for the construction of a bridge and roadway over the P-1 Channel in the general vicinity of S.W. 7th Street . Such construction shall be completed prior to the receipt of the first chlorine tank car on the subject site . The road shall include all necessary improvements as determined by the Public Works Department , including signalization for which the applicant will be responsible for a reasonable pro rata share . Mr . Jim Hanson City of Renton September 27 , 1983 Page Three Response : Per our June 6th letter and response at the hearing, Metro has always planned and originally proposed providing access to the eastern portion of the plant property via S .W. 7th Street and a bridge over the P-1 Channel to the northeast corner of Metro 's site . Although not specifically required above , Metro plans to extend S.W. 7th Street from its present terminus westerly to the point of the future Valley Parkway and S.W. 7th Street intersection along with provisions for future signalization. In a recent meeting with the Public Works Department , we were informed that the City only had a roadway easement and not a utility easement . We will continue coordinating with the City Public Works Department to determine the roadway requirements . It is our intent to provide access to Metro 's property as discussed above in conjunction with our next construction contract , IIC - Solids Handling.. Condition #3 : Metro shall improve the alignment of Monster Road along the western boundary of the subject site , including the intersection of Monster Road and Longacres Drive . Response : Monster Road will be improved along Metro 's west property line . . Improvements include a 24 ' wide , 2" class B asphalt roadway with improved drainage and site distance. Monster Road would also be realigned to intersect with Longacres Drive .

With the overlap of the IIB and IIC contracts , we can ensure that any requirements applicable to IIB can be implemented in a timely fashion . Upon submittal of this.. letter , it. is our understanding that a foundation permit will be issued and ultimately a building permit . We expect that the City will cooperate with Metro on the implemen- tation of this mutually beneficial project . The treatment plant flows are now exceeding the design capacity and it is important that we proceed as soon as possible . Our schedule must be maintained to enable us to meet our legislative mandate . Because of the dynamic nature of this project , we would like to propose that a joint Metro and City of Renton management level project review committee be established . We would propose that the committee include the Directors of Public Works , Building and Zoning, the Fire Department Chief representing the City, and project management representatives from Metro . Further , we would propose meeting in the next. two (2 ) weeks to discuss _ this proposal . Thank you for your. attention to this matter and look forward to your assistance on this project .

The Hearing Examiner's decision did not specifically discuss the inclusion of the substation, but it did not specifically prohibit it since it was included in the.original application. It is, therefore, our opinion that the substation itself was included as a portion of the conditional use permit, but the effluent pumping plant was specifically excluded as part of the approval. This was clearly stated both in the staff report and public hearing before the Land Use Hearing Examiner. If we can be of any further assistance, please contact our office. Sincerely, t R Roger J.

Jim Hanson City of Renton Building and Zoning Department 200 Mill Avenue Renton , Washington 98055 Renton Treatment Plant Enlargement : Status of Conditional Use Permit Requirements Dear Mr . Hanson : The purpose of this letter is to respond to the City of Renton 's staff request concerning Metro 's plans for implementing the eight (8) conditions outlined beginning on Page 7 of the City 's conditional use permit No . METRO: CU-007-83 . The City has requested this information in conjunction with Metro 's applica- tion for a building permit for the Renton Treatment Plant Enlargement IIB - Liquid Stream. This letter is also a follow-on to our letter of June 6 , 1983 (attached ) , and our responses to the hearing examiner at the hearing of June 28 , 1983 documented on Page 3 of the conditional use permit . To refresh your memory, the conditional use permit was issued in regard to the $123 million Renton Treatment Plant Enlargement project which is a phased construction program composed of the following contracts : Start Completion Phase Date Date IIA - Site Preparation May 1983 Sept . 1984 IIB - Liquid Stream Enlargement Sept . 1983 Jan . 1986 IIC - Solids Stream July 1984 June 1987 IID - Computer Automation May 1984 June 1987 IIE - Plantwide Landscaping , Spring 1986 Sept . 1987 Mr . Jim Hanson City of Renton September 27 , 1983 Page Two This project is a joint effort by the State Department of Ecology and Metro and the funding has been secured . Because of the fast-track nature of this project it has been Metro ' s intent to implement most of the City 's conditions during construction of the IIC - Solids Handling facilities . This was previously discussed with City building and public works officials and outlined in our June 6th letter with no objection previously raised by the City . The following is the status of our efforts to implement the eight (8 ) conditions outlined in the conditional use permit : Condition #1 : The applicant provide affirmation that the Metro Council will permit Metro to participate in an LID which may be created to construct , improve or build the Valley Parkway Oaksdale Road ) . Response : As stated by our June 6th letter , Metro has no ojec- tion to possible participation in an LID to extend S.W. 7th Street to the intersection of the future Valley Parkway and then northerly and westerly over the P-1Channel to 400 + feet beyond intersecting Monster Road. It has been Metro 's frequent practice in other locations to cooperate in the LID process as long as the ultimate cost obligation to Metro is equitable . We are presently exploring what action must be taken by the Metro Council to comply with this condition since the City has not filed a petition. We will coordinate with the City in this regard . Condition #2 : Metro shall be responsible for the construction of a bridge and roadway over the P-1 Channel in the general vicinity of S.W. 7th Street. Such construction shall be completed prior to the receipt of the first chlorine tank car on the subject site . The road shall include all necessary improvements as determined by the Public Works Department , including signalization for which the applicant will be responsible for a reasonable pro rata share . Mr . Jim Hanson City of Renton September 27 , 1983 Page Three Response : Per our June 6th letter and response at the hearing , Metro has always planned and originally proposed providing access to the eastern portion of the plant property via S .W. 7th Street and a bridge over the P-1 Channel to the northeast corner of Metro 's site . Although not specifically required above, Metro plans to extend S.W. 7th Street from its present terminus westerly to the point of the future Valley Parkway and S .W. 7th Street intersection along with provisions for future signalization . In a recent meeting with the Public Works Department , we were informed that the City only had a roadway easement and not a utility easement . We will continue coordinating with the City Public Works Department to determine the roadway requirements . It is our intent to provide access to Metro 's property as discussed above in conjunction with our next construction contract , IIC - Solids Handling. Condition #3 : Metro shall improve the alignment of Monster Road along the western boundary of the subject site , including the intersection of Monster Road and Longacres Drive . Response : Monster Road will be improved along Metro ' s west property line . Improvements include a 24 ' wide , 2" class B asphalt roadway with improved drainage and site distance . Monster Road would also be realigned to intersect with Longacres Drive . Metro would provide approximately 50% of the 60 ' right-of- way and extend the Monster Road 24 ' wide , 2" class B asphalt roadway with drainage to Longacres Drive . Metro would be allowed access to this roadway . Minor intersection improvements would be included , however , no other improvements to Longacres Drive would be provided . This commitment is contingent upon developing a reasonable and equitable right-of-way plan with the neighboring property owner and the results of more detailed design in coordination with the City . Metro is presently working with the Public Works Department to refine the design of these improvements for inclusion in the IIC construction contract . Condition #4 : The applicant shall dedicate one-half ( I ) of the right-of-way for the Valley Parkway between the P-1 Channel and Monster Road . Mr . Jim Hanson City of Renton September 27 , 1983 Page Four Response : Metro will dedicate one-half ( 2 ) of the right-of-way for Valley Parkway within its property between the P-1 Channel and Monster Road . This will be accomplished prior to obtaining a building permit for the IIC construction phase . Condition #5 : Metro may seek latecomers agreements as determined by the City Council for any aspect of roadway improvements . Response : No comment . Condition #6 : The applicant will prepare a risk analysis of the chlorine tank car operation and will coordinate with the Police and Fire Department to provide for an evacuation plan for the area in the event of any chlorine leak . Response : Metro is presently preparing a risk analysis and emergency evacuation plan which would be submitted to the City for review in January , 1984 .

It has undergone an in-depth study by METRO., D.O.E. and EPA. This project coordinates very closely with the development 'of the P-1 Channel, which was granted a Shoreline Substantial Development Permit (SM-93-81) in April of 1982. In actuality, METRO will begin the construction of the first phase of the P-1 Channel.. Enclosed are both the staff reports and Land Use Hearing Examiner decisions related to the project. I have only enclosed reductions of the design plans because of the bulk of the scale drawings. We anticipate some minor revisions in the engineering of these plans, but no major changes in layout of the plant or basic design. I am sure that you are aware of the critical nature of the expansion of the sewage treatment plant. This facility is presently operating over design capacity and represents a major environmental threat if it failed. This Shoreline Substantial Development Permit does not include the proposed tunnel from the site to Puget Sound. The City of Renton considers this a separate and distinct issue. Thank you very much for your time. If you have any questions, please call me at (206) 235-2550. Sincerely, CA:—BL1L6jed Roger J. Blaylock Zoning Administrator R JB:se Encl. July 12, 1983 OFFICE OF THE LAND USE HEARING EXAMINER CITY OF RENTON JUL 1 2 1985 REPORT AND DECISION. APPLICANT: METRO FILE NO. CU-007-83 Municipality of Metropolitan Seattle LOCATION: 1200 Monster Road S.W. SUMMARY OF REQUEST: Applicant seeks approval of a conditional use permit to allow the expansion of the sewage treatment plant in a G-1 Zone. SUMMARY OF ACTION: Building and Zoning Department Recommendation: Approval, subject to conditions. Hearing Examiner Decision: Approval, subject to conditions. BUILDING & ZONING The Building & Zoning Department Report was DEPARTMENT REPORT: received by the Examiner on June 21, 1983. PUBLIC HEARING: After reviewing the Building and Zoning Department Report, examining available information on file with the application and field checking the property and surrounding area, the Examiner conducted a public hearing on the subject as follows: The hearing was opened on June 28, 1983, at 10:05 a.m. in the Council Chambers of the Renton Municipal Building. Parties wishing to testify were affirmed by the Examiner. The following exhibits were entered into the record by the Hearing Examiner: Exhibit #1: Yellow file containing the application, letter dated June 6, 1983 which substantially revised the application, and other pertinent documents. Exhibit #2:General vicinity map showing the subject site. Exhibit #3: Specific site plan map. Roger Blaylock, Zoning Administrator, presented the staff report. He indicated METRO is preparing an environmental impact statement on the tunnel and pump plant; consequently, that should be excluded from this conditional use permit and would require a supplemental permit for that portion itself. With the development of the plant, there would be continued growth in the region. It was pointed out that there would not be major operational truck traffic; the two operational points seen by staff would be the exiting of solids from the northeast corner of the site and the servicing of septic pump stations. Mr. Blaylock then reviewed the site plan map. Testifying at this point was: David Healey Brown & C aldwell 100 W. Harrison Street Seattle, WA 98119 Mr. Healey stated there will not be any new primary treatment facilities under this expansion, only secondary treatment facilities. r METRO: CU-007-83 Municipality of Metropolitan Seattle July 12, 1983 Page 2 Mr. Blaylock reported that there will be tank cars of liquid chlorine; the building is designed to handle two chlorine tanks or the interchanging of two chlorine tanks stationed in the building. Solids will be taken out to appropriate dump sites such as fertilizer projects, farming activities, etc. The Examiner asked if the structures to the north would be below the flood level or above. Mr. Blaylock indicated they would be above flood level. Mr. Healey explained their method of measuring sea level, which is starting with an elevation of 100 for mean sea level because there are some structures that are below sea level. The Examiner asked what that means to the city as far as their flood storage capacity is concerned. Mr. Healey indicated the dike will be moved out on the east side to approximately the property line and on the North side to just north of the digesters. Mr. Blaylock pointed out that the development will require the construction of a culvert type bridge across the P-1 Channel to the northeast corner of Metro's present site and creates a new primary operational access to the site and will be utilized for sludge truck hauling in the future; further, it provides a faster emergency access for fire equipment. Mr. Blaylock noted that reference is made to Valley Parkway in the staff report on page 5, Item 8, and that should be amended to reflect Oakesdale instead of Valley Parkway. Further, that Metro has indicated they would not object to participation in an L.I.D. to extend S.W. 7th, which would actually be the Parkway, from S.W. 7th over to Monster Road; the problem they have at this time is that their staff can say they will recommend this to the Metro Council, but Metro Council must make the final decision. The other option they could have is that through dedication, they could improve, and the city could then come back and grant a latecomers agreement to Metro. The Examiner inquired how often the tank car of chlorine would be changed per year. Mr. Healey indicated that it would be once every two months initially; once at design capacity, it would probably be once a month. However, he stated that the chlorine is now being brought in every two weeks because of the reduced capacity for storage. The Examiner then questioned whether the anarobic digesters would be a problem in the area. Mr. Healey advised that generally they are not if they are operated properly and not overloaded; that every effort will be made to keep odors to a minimum. Mr. Blaylock closed his report by indicating that the staff recommends approval of the conditional use permit, subject to the following eight (8) conditions: 1. Approval of an appropriate fire protection system meeting the City of Renton's code requirements by the Fire Department. 2. Construction of S.W. 7th Street from its existing completion point at Washington Technical Center to the subject site. Construction will include the intersection at the Parkway and S.W. 7th Street with provisions for future signalization. 3. Construction of a culvert-type bridge over the P-1 Channel to the N.E. corner of Metro's site, to include and be approved by the Public Works Department. The Public Works Department shall be granted full authority to determine whether the excavation of the P-1 Channel to its designed section through the bridge area should be required. This item should not be appealable to either the Hearing Examiner nor the City Council because the City has previously approved the necessary design configuration for the P-1 Channel. 4. Metro shall dedicate one-half of the right-of-way for the Parkway and its improvements along the northern property line. This dedication shall be a minimum of 40 feet in width to comply with the needs of an industrial collector arterial. 5. Metro shall signalize the intersection at S.W. 7th Street and the Parkway at the time determined by the Board of Public Works. This may correspond with the development of Phase 2 or Phase 3 of Washington Technical Park. At that time, a proportionate share between the developers of Washington Technical Park and Metro shall be calculated. METRO: CU-007-83 Municipality of Metropolitan Seattle July 12, 1983 Page 3 6. Metro shall sign` restrictive covenants or to participate in an LID extension of the Valley Parkway from S.W. 7th Street over the P-1 Channel to 400 feet beyond the intersection of Monster Road. 7. Metro will improve Monster Road along Metro's western property line along with a realignment to be approved by the Public Works Department to connect monster Road to Longacres Drive to a standard of 24' wide, 2" Class B asphalt roadway, with improved drainage. This will include minor intersection improvements at the intersection of Longacres Drive and Monster Road. 8. Metro shall prepare a risk analysis of the shipment of chlorine and operation of its proposed chlorination facility as it relates to the City of Renton's disaster plan. This shall include a specific evacuation plan. The Examiner called on the applicant or representative. Testifying was: Susan Solberg Metro Municipality of Metropolitan Seattle 821 - 2nd Avenue Seattle, WA 98104 Ms. Solberg indicated that everything explained to her by Mr. Blaylock had been explained adequately and that with reference to the conditions, she offered the following comments: Condition #1: No problem with this. Condition #2: No problem with this, but they would ask that the Council consider a latecomer's agreement for other property owners for participation in that part of 7th Street that Metro constructs; being that portion from the P-1 Channel to where 7th terminates now. Condition #3: No problem. Condition #4: Agree subject to Metro's Council approval; staff cannot commit Council to this dedication of property. Condition #5: Agree to and again ask for latecomer's agreement if put in by Metro. Condition #6: Must obtain Metro Council's approval to commit to. Condition #7: Agree. Condition #8: Agree. The Examiner called for further testimony in support of the application. There was none. The Examiner then called for testimony in opposition to the application. There was none. The Examiner closed the hearing, with the approval of Metro representatives, at 1:05 p.m. and noted his decision would be issued within two weeks. FINDINGS, CONCLUSIONS & DECISION: Having reviewed the record in this matter, the Examiner now makes and enters the following: FINDINGS: 1. The applicant, the Municipality of Metropolitan Seattle (METRO), filed a request for approval of a conditional use permit to allow the construction of additional sewage treatment handling facilities. 2. The application file containing the application, SEPA (State Environmental Policy Act; RCW 43.21C) documentation, the Building and Zoning Department Report, and other pertinent documents, was entered into the record as Exhibit #1. METRO: CU-007-83 Municipality of Metropolitan Seattle July 12, 1983 Page 4 3. Pursuant to the City of Renton's Environmental Ordinance and SEPA, an Environmental Impact Statement prepared under federal auspices was utilized to review the subject proposal's environmental impact. 4. Plans'for the proposal have been reviewed by all city departments affected by the impact of this development. 5. The subject property is located in the extreme westerly portion of the city near the intersection of Monster Road and Longacres Parkway. 6. The subject site is fully dedicated to the Metro Renton Sewage Treatment Plant. The site is presently developed with facilities to accommodate the sewage generated by the existing communities on the east side of Lake Washington. The existing plant is currently operating at and on some occasions over capacity. The proposed additions would double the treatment capacity of the Renton plant. 7. The proposed additions will include as major elements: new aeration tanks, secondary sedimentation tanks, chlorination facilities, solids (sludge) processing facilities, and the construction of an effluent pump station and a tunnel to convey the effluent to an outfall in Puget Sound. The final item, the tunnel, is still under consideration by the Metro Council and further studies have been commissioned. 8. Part of the subject site was annexed into the city in April of 1959 by Ordinance 1745 and amending Ordinance 1764. Other portions of the site were annexed by Ordinance 1928 in December of 1961. The site, zoned G-1 at the time of annexation, is still zoned G-1. 9. The water system for fire flow requires modification, but the nature of the facility, a sewage treatment plant, requires specialized water systems to prevent backflow and possible contamination of public water supplies. Metro proposes working with the city departments to assure adequate fire protection for the subject site. 10. The Fire Department is especially concerned with the on-site storage of a chlorine tank car. Depending on the size of the car and Metro's needs, tank cars will be delivered to the site in the range of 1 to 2 cars monthly. The tank cars could range in size from 30 to 55 to 90 ton cars, depending on need and availability. Currently, Metro receives a 1-ton cylinder weekly. The chlorine tank car will be separated from the string of freight cars and will be placed entirely within a contained building. Facilities and equipment for containing and handling spills and other potential emergencies will be available at the site and an agreement to work with the Renton Fire Department has been assured. 11. The applicant has already applied for permission to grade and fill the subject site. The material will be generated both on-site and off-site from the proposed P-1 Channel. The storm drainage potential of the site will be maintained and the proposed structures will be above the level of expected flood waters in the event of a flood situation. 12. Development of the site will not generate much additional traffic during peak hours as the plant will be largely automated. Heavy vehicle traffic will be generated during construction with the importation of building and fabrication materials including steel and concrete. 13. The site will also generate traffic which will be involved in moving solids and sludge, from the site to remote locations. This operation will generate approximately 8 to 10 vehicle trips per day. METRO: CU-007-83 Municipality of Metropolitan Seattle July 12, 1983 Page 5 14. The applicant has agreed to construct and participate in the construction of a substantial number of roadway improvements in the vicinity of the subject site. The applicant will provide a culvert type of bridge across the P-1 Channel as an extension of S.' W. 7th Street from the Washington Technical Park. This roadway would provide an alternative route to the site and would provide an expedient route for emergency vehicles from downtown Renton. The Public Works Department will have ultimate approval of the structural components and the design aspects of the bridge. Any traffic signalization necessary will be pro-rated among the potential users in the area. Metro, upon approval of the Metro Council, would be willing to participate in an LID for the improvement of S. W. 7th Street from its current terminus to approximately 400 feet beyond its intersection with Monster Road. Staff recommended that such approval be a condition precedent to finalization of the conditional use permit. Metro will dedicate one-half of the right-of-way for the Valley Parkway along the northern reaches of its property, generally bounded by the P-1 Channel on the east and Monster Road on the west. 15. Metro has acquired additional property which would permit the realignment of Monster Road and its intersection with Longacres Drive. Further arrangements with an additional property owner will be necessary to accomplish this realignment. Metro will provide approximately 50% of the width of the right-of-way. 16. Odors emanating from the site should be largely contained by stack scrubbers which will be installed above the raw sewage receiving station. Hoods also placed over the sludge dewatering complex will direct air to the scrubbers for odor elimination. 17. The site currently is the primary treatment plant for sewage generated by the communities on the east side of Lake Washington. Included) not only the host city Renton, but also Bellevue, Kirkland, Kent, Auburn, Redmond and Tukwila, as well as the unincorporated but serviced areas of King County. Since the treatment plant has been operating above its design capacity, many of these jurisdictions faced decisions concerning the rate of growth in their respective communities. The Comprehensive Plan for the City of Renton forecasted an increase in population, but this could only occur if a method of handling sanitary waste water was available. Similar planning in other communities was also similarly affected. The expansion of the Renton Sewage Treatment Plant will enable further development of the eastside towns commensurate with the available land areas and steady demand. 18. The area in which the subject site is located is designated as suitable for the development of public and quasi-public uses in the city's Comprehensive Plan. 19. The area is generally developed with industrial uses although development of the area is just beginning. The Longacres Race Track is located south of the subject site. Across Springbrook Creek is an area now being developed with manufacturing park type uses, including light industrial, warehousing and office uses. The area has been in transition from rural and generally open space uses to commercial and manufacturing uses and the remaining single family home in the immediate vicinity is expected to yield to the transition to more intense uses rather than signify the residential character of the area. 20. The traffic generated by the proposal as outlined in earlier findings will be predominately of a non-peaking hour character, consisting largely of the initial construction vehicles; the daily crew, which is limited by the generally automated nature of the facility, and the sludge bearing trucks leaving the site. The rail delivery of the chlorine tank car presents the greatest concern to the emergency services as the potential for harm is present from accidents both on-site and in transport through the city. Staff has recommended that Metro prepare a risk analysis and evacuation plan for the area. METRO: CU-007-83 Municipality of Metropolitan Seattle July 12, 1983 Page 6 Chlorine gas, since it is heavier than air, would tend to settle and hug the ground. The fact that the subject site and vicinity is already low lying in relationship to the majority of the residential areas should minimize the risk somewhat although the working population and race track patronage could be at risk. The nearby location of the P-1 Channel topographically lower even yet could also channel any escaping gas to safer areas. Included as part of any emergency plan is the connection of the site via the proposed S. W. 7th Street Bridge and roadway extension. This should be required to be available prior to the storage of tank car quantities of chlorine on the subject site. 21. The applicant has proposed a major landscaping effort on the subject site. Both the applicant and city staff have emphasized the landscaping, shading and buffering along the P-1 Channel for both aesthetic and environmental reasons. Shade trees will keep the water temperature lower to enhance the fish populations which now migrate throughout Springbrook Creek. Landscaping will also be utilized to harmonize the site with other proposed landscaped manufacturing parks in the area. CONCLUSIONS: 1. The approval of a conditional use permit to allow the expansion of the Renton Sewage Treatment Plant appears to serve the public use and interest. The current plant which serves the growing urban centers on the east side of Lake Washington is presently operating beyond its design capacity. Expansion will enable the plant to adequately process sewage now generated by these communities, as well as the additional sewage these communities will generate in the face of anticipated growth. 2. The Comprehensive Plans of not only the host city, Renton, but of all the other eastside cities project increases in population and employment which would not be possible unless the plant were permitted to expand to serve these uses. The proposed doubling will meet these needs and at the same time eliminate the overflow problems which now periodically occur. 3. The expanded plant will process greater amounts of sewage and will need not only more tanks, chlorine and pumps, but larger systems to handle some of the sewage. The dewatering operation will generate additional truck trips, and the effluent increase will demand more chlorination and an entirely new method of disposing of the effluent. The precise nature of the effluent disposal system is still under review, but the probable method will not include further discharges into the Green/Duwamish River system. 4. The increased handling capacity will increase to some extent the demand on city services, including roads, water and potential demands on the city's emergency services. As a consequence of these increased demands, Metro will provide some measure of improvements to the roads and arterials surrounding the subject site. These roadway improvements will permit better access to the site for Metro's own purposes, sludge removal, equipment delivery, etc., and will improve access to the site by city emergency equipment should the need arise. These improvements will also facilitate the movement of all vehicles around the site. The current configuration of roads surrounding the site is generally circuitous and a result of happenstance. The realignments and extensions proposed will directly benefit the general public and, as a result of these improvements, the additional loads placed on the system by Metro should not adversely affect traffic . 5. The area no longer serves as a residential area and the proposed use is entirely in conformity with the Comprehensive Plan for the area in which the subject site is located. It also complies with the more far reaching intent of the Renton's Comprehensive Plan to accommodate larger poulations and an enhanced employment base. Further, it can safely be stated that the expansion is generally in compliance with most of the eastside communities' Comprehensive Plans which project greater growth in population in the already established urban centers. METRO: CU-007-83 Municipality of Metropolitan Seattle July 12, 1983 Page 7 6. The enlargement of the plant will also carry with it an improvement of technologies to handle the solids and effluent, as well as some of the other by-products which includes odiferous compounds. The new facilities should further minimize odors generated by the operation both at the receiving end of the operation and during some of the intermediate stages by scrubbing the air before releasing it into the atmosphere. 7. The area, as indicated, has been long in transition from rural residential to industrial and manufacturing park uses, and the plant has generally been an inobtrusive neighbor to those uses. The new odor handling equipment should help further the plant's acceptability as an industrial neighbor. 8. Landscaping, as approved by the city, should also enhance the outward appearance of the plant and blend it into its environs, including the P-1 Channel and the landscaped manufacturing parks which are developing in the area. Landscaping shall provide a dense buffer along the facility's property lines, especially where those lines coincide with other than public streets. Landscaping, as appropriate to shade and moderate the temperatures of the P-1 Channel, shall be installed. All landscaping shall be subject to review and approval by the city's landscape architect. 9. The applicant will comply with the general building regulations of the city and will, therefore, provide adequate parking for supervisory personnel. Beyond the ordinary codes and regulations is the Fire Department's concern regarding the storage of chlorine on the subject site. Staff has indicated that Metro should provide a risk analysis of the plant and a specific evacuation plan. Any such plans should be formulated with the cooperation of the city's emergency response teams, including the Police and Fire Departments. 10. The applicant, as outlined in the findings above, will participate in certain roadway improvements, will provide land for other needed roadway modifications, and will participate, subject to approval by the Metro Council, in an LID for roads adjacent to the subject site. Staff has indicated that the LID approval of the Metro Council be made a condition precedent to issuance of the conditional use permit. Other roadway improvements have apparently been agreed to by the city and Metro staff in a fashion which avoids the need for subsequent Metro Council review. 11. In conclusion, the proposal appears to comply with the various criteria enumerated in Section 4-748 in that the proposed use is in the public interest, is generally compatible with surrounding uses, will use appropriate technology to minimize odors, will comply with the city's codes and ordinances, will be heavily landscaped and will provide construction, land and willingness to participate in roadway improvements which are necessary in this general area. DECISION: The conditional use permit is approved, subject to the following conditions: 1. The applicant provide affirmation that the Metro Council will permit Metro to participate in an LID which may be created to construct, improve or build the Valley Parkway Oaksdale Road). 2. Metro shall be responsible for the construction of a bridge and roadway over the P-1 Channel in the general vicinity of S. W. 7th Street. Such construction shall be completed prior to the receipt of the first chlorine tank car on the subject site. The road shall include all necessary improvements as determined by the Public Works Department, including signalization for which the applicant will be responsible for a reasonable pro rata share. 3. Metro shall improve the alignment of Monster Road along the western boundary of the subject site, including the intersection of Monster Road and Longacres Drive. METRO: CU-007-83 Municipality of Metropolitan Seattle July 12, 1983 Page 8 4. The applicant shall dedicate one-half (1/2) of the right-of-way for the Valley Parkway between the P-1 Channel and Monster Road. 5. Metro may seek latecomers agreements as determined by the City Council for any aspect of roadway improvements. 6. The applicant will prepare a risk analysis of the chlorine tank car operation and will coordinate with the Police and Fire Departments to provide for an evacuation plan for the area in the event of any chlorine leak. 7. The fire flow system provided by the applicant shall be subject to the approval of the Fire Department. 8. Landscaping as approved by the City of Renton Landscape Architect.

Shinpoch Councilman Richard M. Stredicke Richard Houghton, Public Works Director David Clemens, Policy Development Director Ronald Nelson, Building & Zoning Director Roger Blaylock, Zoning Administrator Lawrence J. Warren, City Attorney Members, Renton Planning Commission Renton Record-Chronicle The Appearance of Fairness Doctrine provides that no ex parte (private one-on-one) communications may occur concerning land use decisions. This means that parties to a land use decision may not communicate in private with any decision-maker concerning the proposal. Decision-makers in the land use process include both the Hearing Examiner and members of the City Council. All communications concerning the the proposal must be made in public. This permits all interested parties to know the contents of the communication and would allow them to openly rebut the evidence. Any violation of this doctrine would result in the invalidation of the request by the Court. The Doctrine applies not only to the initial public hearing but to all Requests for Reconsideration as well as Appeals to the City Council. METRO: CU-007-83 Municipality of Metropolitan Seattle July 12, 1983 Page 9 Pursuant to Title IV, Section 3015 of the City's Code, request for reconsideration must be filed in writing on or before July 26, 1983. Any aggrieved person feeling that the decision of the Examiner is based on erroneous procedure, errors of law or fact, error in judgment, or the discovery of new evidence which could not be reasonably available at the prior hearing may make a written request for review by the Examiner within fourteen (14) days from the date of the Examiner's decision. This request shall set forth the specific errors relied upon by such appellant, and the Examiner may, after review of the record, take further action as he deems proper. An appeal to the City Council is governed by Title IV, Section 3016, which requires that such appeal be filed with the City Clerk, accompanying a filing fee of $75.00 and meeting other specified requirements.

DEPARTMENT ANALYSIS; 1. The subject site area is designated on the Comprehensive Plan as Public/Quasi-Public. The proposed expansion of the Metro sewage treatment plant facility is in general compliance with the Comprehensive Plan. 2. The proposal is being heard as a conditional use permit as the result of the underlying G-1, General Use Zoning, of the subject site. The Land Use Examiner must apply the eleven criteria delineated under Section 4-748 to consider acceptability of the proposal. 3. The proposed expansion by Metro (Municipality of Metropolitan Seattle) of the Renton 'Sewage Treatment Plant is the largest single public development project ever proposed within the City of Renton. The expansion would functionally double the size of the treatment plant and provide for specialized solids processing. The Metro Council adopted the basic program in 1981 to consist of three major elements: (1) construction of new aeriation tanks, secondary sedimentation tanks, and chlorination facilities for a liquid stream capacity of 72,000,000 gallons daily, (2) construction of solids processing facilities for on-site concentration, stabilization, and de-watering of wastewater sludges from the 72,000,000 gallon daily liquid stream facility, and (3) construction of effluent pumping station, tunnel, and outfall for transfer and disposal of treatment effluent in Puget Sound. The majority of the third condition requiring the pumping and tunnel for the disposal of treated effluent in Puget Sound will not be within the city limits of the City of Renton. The initial pumping station and beginning of the tunnel will be, and is, included as part of this application. 4. The Environmental Review of the proposed project was originally conducted under NEPA (National Environmental Policy Act) and is not subject to specific review under SEPA. The Environmental Review Committee considered the proposal, even though it was not within their purview to do so, and recommended that Metro modify their application to address specific problems both on-site and off-site. Metro subsequently modified their application on June 6, 1983 to address those concerns. 5. The subsequent application is of such unusual size and scope, with a total estimated cost of approximately $110,000,000, that the following specific breakdown of proposed improvements is presented for clarification: Liquid Stream: Major liquid stream improvements at the Renton plant include: a. Construction of new aeration tank. b. Construction of eight (8) new secondary sedimentation tanks and appurtenant pumping systems and distribution channels. c. Retrofit of existing secondary sedimentation tanks with new hydraulic controls. PRELIMINARY REPORT TO THE HEARING EXAMINER MUNICIPALITY OF METROPOLITAN SEATTLE: CU-007-83 JUNE 28, 1983 PAGE 4 d. Continued use of chlorine for effluent disinfection and construction of a chlorine building for receiving and storing bulk chlorine in rail tank cars. The subject of chlorine safety was discussed with the City of Renton Fire Chief and Fire Marshall during the predesign study. The. new chlorine building will have access control and entry detection devices on all doors and windows, as well as safety systems to contain and dispose of any chlorine leaks inside the building. e. Construction of a second chlorine contact channel. f. Construction of a septage dilution tank to reduce the strength of septage discharged to the influent and to control odors. Solids Stream: Solids processing facilities will include the following major improvements: a. Construction of a raw sludge blending/distribution tank. b. Construction of four (4) dissolved air flotation thickeners for thickening of combined primary and waste activated sludge. c. Construction of a thickened sludge blending tank. d. Construction of four (4) anaerobic digesters for stabilization of thickened sludge. e. Construction of a blending digester for storage of digested sludge prior to dewatering. f. Construction of a sludge dewatering building for belt filter presses and chemical storage (polymer). g. Construction of covered loading facilities for removal of dewatered sludge from the plant site by semi-trailer trucks. h. Construction of a storage tank for belt filter press filtrate. Other Improvements: Other improvements to be done as part of the on-site expansion include the following: a. Construction of a new electrical substation. b. Installation of a new computerized process control system. c. Construction of tunnels and roads for access to and maintenance of pipelines, process equipment and tanks. d. Construction of outside piping systems such as storm drains, tank drains, and air, water and chemical piping systems. e. Minor structures and process improvements such as a new prechlorination manhole, an influent flow measuring station, replacement of existing pumps with more efficient models and modifications to the grit and screenings systems. 6. The subject site is located within the flood plain of Springbrook Creek. The on-site.improvements include revisions to the dike and filling approximatey 27,500 cubic yards within the existing flood plain. In accordance with the City of Renton Environmental Review Committee's requirement to provide for compensative flood storage, Metro has started excavating the P-1 Channel. They have agreed to place a total of 99,000 cubic yards of material upon the treatment plant site out of the flood plain from the P-1 Channel. The first phase of construction of the P-1 Channel includes the excavation of 50,000 cubic yards of material. The Building and Zoning Department has issued an annual license to Metro under the special permit requirements of King County Department of Public Works, File No. SP-060-81. This will provide more than twice the flood storage capacity that is required for their proposed fill operation under this development. In addition, they have agreed to take another 49,000 cubic yards from the Four Bay area as the P-1 Channel is exccavalt .. PRELIMINARY REPORT TO THE HEARING EXAMINER MUNICIPALITY OF METROPOLITAN SEATTLE: CU-007-83 JUNE 28, 1983 PAGE 5 7. The proposed expansion doubles the size of the Renton Treatment Plan. Based on these substantial modifications the access for both servicing and emergency needs were modified. The Washington Technical Industrial Center, located east of the proposed P-1 Channel location, included the extension of SW 7th to the P-1 Channel. METRO has proposed at the request of both the Public Works Department and the Fire Department, the construction of a culvert type bridge across the P-1 Channel to the northeast corner of METRO's present site. This provides a new primary operational access to the site and will be utilized for sludge truck hauling in the future. In addition, it provides a faster emergency access from the downtown fire station. METRO may ask City Council for a late corner's agreement for the improvement of SW 7th Street. Discussion on the proportional share of the actual signalization of the intersection of the Valley Parkway and SW 7th can be evaluated at a future time. Public Works Department reserves all approval on all plans for the bridge, street improvements, and intersection improvements for this extension of SW 7th Street. 8. METRO has also revised their application to include the dedication of one-half of the right-of-way for the Valley Parkway and improvements along the northern propoerty line of the subject site. This is on the alignment for the extension of the Valley Parkway west of the P-1 Channel to interconnect with Monster Road. METRO has also stated that it has no objection in participating in an LID to extend SW 7th Street to the intersection of the future Valley Parkway and then northerly and westerly over the P-1 Channel to 400 feet beyond the intersection with Monster Road. METRO points out that its staff cannot make a commitment to an LID and the commitment must come directly from the METRO Council after it has an opportunity to review the petition. It would appear that in this case the City would be delinquent in not requiring the filing of restrictive covenants as a condition of the conditional use permit to participate in that LID. The alternative to METRO is to construct that one-half of the right-of-way, basically two lanes out of a proposed four lane major arterial, and obtain late corner's fees from subsequent developments utilizing that stretch of the Valley Parkway through late corner's agreements. 9. METRO recently acquired an adjacent parcel of property owned by Burlington Northern. They have agreed to realign Monster Road to intersect with Longacres Drive through this newly acquired parcel of property. METRO will provide approximately 50% of the 60 foot of right-of-way and extend Monster Road to that intersection. They do require access to this roadway for both emergency and administrative vehicles. Some minor intersection improvements are to be included in the improvement of Monster Road. This commitment is contingent upon developing a reasonable and equitable right-of-way plan with the neighboring property owner and the results of more detailed design in coordination with the City. Specific design plans will have to be approved by the Public Works Department on the exact realignment of Monster Road. 10. METRO has requested a waiver of improvements on Monster Road along the westerly side of the property and on the segment that would be realigned. The Board of Public Works is considering granting this modification based upon the fact that the major arterial will be the Valley Parkway in this general area and that as little traffic as possible should be directed to this segment of Monster Road. The applicant has agreed to make improvements to include a 24-inch wide, 2-inch Class B asphalt roadway with improved drainage. The Board of Public Works is considering this request based upon METRO's cooperation in dedicating and constructing major portions of the Valley Parkway. PRELIMINARY REPORT TO THE HEARING EXAMINER. MUNICIPALITY OF METROPOLITAN SEATTLE: CU-007-83 JUNE 28, 1983 PAGE 6 12. METRO has also agreed in their letter of June 6th, to upgrade the fire protection facilities to the City of Renton's code requirements. Specific design plans have been submitted to the Public Works Department and the Fire Department for review. METRO has expressed a concerned over guaranteeing the safety of the water quality,in the City mains. The problem results because of possible backdrafts of contaminated water from the sewage into the City's water main system. The present system has an airgap in between the water tower and the main thus creating an appropriate sanitary separation. The problem is enough water flow to recharge the existing reservoir to meet fire flow requirements for the entire site. METRO contends that it should not upgrade the City's area water system but should provide a separate system adequate to meet the fire flow needs of the new facilities. Both sides in the issue wish to reserve the right to negotiate farther on the problem. However, it should be noted that METRO has agreed to meet the City's fire code requirements. The second issue that the Fire Department is concerned with has been the chlorination building. METRO will have a large supply of chlorine stored in a railroad tank car. The building itself meets all hazardous standards requirement for leakages or potential accidents. The new access proposed off of SW 7th Street along with the existing access, provides reassurance in the mind of the Fire Department in reaching the site faster to contain any hazardous situation within the chlorine building. The City should recognize a potential hazard and be concerned with potential plans for evacuation of the general area. It would appear advisable for the City to require METRO to provide a risk analysis of the shipment and operation as it relates to the City's disaster plan. A specific evacuation plan should be recommended to the City in case of a spill. 13. The Land Use Hearing Examiner must consider the following eleven criteria in reviewing a conditional use permit request: Comprehensive Plan: The proposed use shall be compatible with the general purpose, goals, objectives and standards of the Comprehensive Plan, the Zoning Ordinance and any other plan, program, map or ordinance of the City of Renton. The METRO proposed expansion is compatible with the general purpose, goals and objectives and standards of the Comprehensive Plan. The subject site was designated for this specific public use in the original Comprehensive Plan which was adopted in 1965. The plant expansion is critical to the enactment of the Comprehensive Plan for the entire City, for without the necessary sewer utilities the goals of density and community development cannot be achieved. Community Need: There shall be a community need for the proposed use at the proposed location. Presently there is a dramatic community need for the proposed expansion of the sewage treatment plant. Present volumes exceed design operational capacity of the present plant. Without the expansion, basic development in the cities of Kirkland, Bellevue, Renton, Auburn and Kent would be completely stopped. In general, it could be said that the plant will create major impacts because of an over concentration of its particular use. However, because of the design of sewers, this is the most logical location for a treatment plant within the entire sewage drainage basin. Renton has accepted the responsibility of this type of land use within its city limites to provide services to the adjoining communities. Effect on Adjacent Properties: The proposed use at the proposed location shall not result in substantial or undue adverse effects on adjacent property. The expansion of the METRO sewage treatment plant will increase the effectiveness and effeciency of the existing operation. Presently, it may be considered to create some adverse affects on adjacent properties in the form of odors and unsightliness. The proposal will increase the handling capacity and the degree of treatment along with providing major landscaping buffers and updated landscaping program for the entire complex. PRELIMINARY REPORT TO THE HEARING EXAMINER MUNICIPALITY OF METROPOLITAN SEATTLE: CU-007-83 JUNE 28, 1983 PAGE 7 The proposal complies with the requirements of lot coverage, yards and building heights for the G-1 zone. The future power substation though, will have equipment which exceed the 35 foot height limit. Utilities have not be specifically limited in height because of their typical overhead nature and , size of equipment involved. Compatibility: The proposed use shall be compatible with the residential scale and character of the neighborhood. There are no adjacent residential neighborhoods in the immediate area. The Comprehensive Plan has designated the entire vicinity as Manufacturing Park or Public Use. There is one adjacent single family residence but it is believed it is transitional in nature and not an established trend. Therefore, the criteria does not comply. Parking: Parking areas shall not be allowed in the front, side and rear yard setbacks except upon approval by the Hearing Examiner as provided in Section 4-708(B)(3)(a). Parking under the building structure should be encouraged. Lot coverage may be increased to as much as seventy-five percent (75%) of the lot coverage requirement of the zone in which the proposed use is located if all parking is provided underground or within the structure. This parking requirement does not really apply to the new expansion. Parking has already been provided per code requirements for the administration building and the worker's on-site. Most of the facility will be automated with primary employment directed towards maintenance. Traffic: Traffic and circulation patterns of vehicles and pedestrians relating to the proposed use and surrounding area shall be reviewed for potential effects on, and to ensure safe movement in the surrounding area. Construction of the site will create the majority of traffic. Large amounts of steel, concrete and finished machinery will be imported into the site. The anticipated filling and grading of approximately 250,000 cubic yards will be conducted almost exclusively on the site and the adjacent P-1 Channel. Minor truck traffic is anticipated with equipment possibly coming to and from the site. The project is of large enough scale that most equipment will probably be stored on the site for the duration of the contract period. Operational traffic is seen primarily in the independent septic pumpers coming in and disposing of the sewage. This presently averages less than 15 vehicle trips per day. Exporting of the sludge from the site would be in major semi trucks and would propably not be greater than 5 trips per week. The function of the redesign is primarily to dewater the material and pump the waste water to Puger Sound through a tunnel. Noise, Glare: Potential noise, light and glare impacts shall be evaluated based on the location of the proposed use on the lot and the location of on-site parking areas, outdoor recreational areas and refuse storage areas. Basic noise and glare will be kept at a minimum from the adjacent landscaping. In the past, the primary problem with the facility has been the generation of odors as a result of overcapacity operation. This should be minimized or possibly totally eliminated with the redesign of the facility. Landscaping: Landscaping shall be provided in all areas not occupied•by buildings or paving. The Hearing Examiner may require additional landscaping to buffer adjacent properties from potentially adverse effects of the proposed use. PRELIMINARY REPORT TO THE HEARING EXAMINER MUNICIPALITY OF METROPOLITAN SEATTLE: CU-007-83 JUNE 28, 1983 PAGE 8 A schematic landscaping proposal has been presented along with the conditional use permit application. It generally provides major buffering along the perimeters of the site adjacent to the proposed P-1 Channel. Total landscaping becomes critical when considering such a large site of 82.6 acres. Specific evaluation should be conducted by the City's Landscape Architect at the time of building permit approval. The primary intent is to blend the large site and make the perimeter landscaping aesthetically pleasing along with enhancing the wild life mitigation proposed in the P-1 Channel. Accessory Uses: Accessory uses to conditional uses such as day schools, auditoriums used for social and sport activities, health centers, convents, preschool facilities, convalescent homes and others of a similar nature shall be considered to be separate uses and shall be subject to the provisions of the use district in which they are located. This criteria does not apply in this case. The entire facility is dedicated to a sewage treatement plant facility. Conversion: No existing building or structure shall be converted to a conditional use unless such building or structure complies, or is brought into compliance, with the provisions of this Chapter. This provision does not apply because the facility has continuously been a sewage treatment and no conversion is sought. Public Improvements: The proposed use and location shall be adequately served by and not impose an undue burden on any public improvements, facilities, utilities and services. Approval of a conditional use permit may be conditioned upon the provision and/or guarantee by the applicant of necessary public improvements, facilities, utilities and/or services. The proposed expansion does not create any undue burden on any public improvement facilities or utilities in the area. This is only true as a result of METRO modifying their application with their letter dated June 6, 1983. This provides for necessary dedications, street improvements, and participation for other public improvements in the general area. The only issue that may remain is the issue of water main extension through the subject site for the general integrity of the City's fire fighting system in this area. The staff's position is that this issue is a technical issue which must be resolved between the Fire Department and METRO. METRO has stated that they will meet the City's fire code requirements, but this does not include a new loop system to upgrade the City's area water system. The philosophical difference is that METRO believes that it must protect its own facility to required code but it should not, because of its unique location and problems associated with water and sewage contamination, provide an intertie to generally upgrade the area's watermain system. 14. Various department comments are attached for the public's and the Examiner's review. These comments have been extensively discussed in both the agreement of METRO to revise their application, dated June 6, 1983. 15. The proposal as presented by METRO is a logical extension of a necessary service to allow continued development of the general region. In the past, the Land Use Hearing Examiner has expressed concern that the sewage facilities was not adequate to allow continued growth without drastic controls. This proposal by METRO basically doubles the size of the plant to allow for that continued growth according to the adopted Comprehensive Plans and zoning of the respective jurisdictions involved in METRO. PRELIMINARY REPORT TO THE HEARING EXAMINER MUNICIPALITY OF METROPOLITAN SEATTLE: CU-007-83 TUNE 28, 1983 PAGE 9 M. DEPARTMENTAL RECOMMENDATION: Based upon the above analysis, it is recommended that the conditional use request, CU-007-83, be approved subject to the following conditions: 1. Approval of an approriate fire protection system meeting the City of Renton's code requirements by the Fire Department. 2.Construction of SW 7th Street from its existing completion point at Washington Technical Center to the subject site. Construction will include the intersection at the Parkway the intersection at the Parkway and S.W. 7th Street with provisions for future signalization. 3.Construction of a culvert-type bridge over the P-1 Channel to the NE corner of Metro's site to include and be approved by the Public Works Department. The Public Works Department shall be granted full authority to determine whether the excavation of the P-1 Channel to its designed section through the bridge area should be required. This item should not be appealable to either the Hearing Examiner or the City Council because the City has previously approved the necessary design configuration for the P-1 Channel. 4. Metro shall dedicate one-half of the right-of-way for the Parkway and its improvements along the northern property line. This dedication shall be a minimum of 40 feet in width to comply with the needs of an industrial collectpr arterial. 5. Metro shall signalize the intersection at S.W. 7th Street and the Parkway at the time determined by the Board of Public Works. This may correspond with the development of Phase 2 or Phase 3 of Washington Technical Park. At that time, a proportionate share between the developers of Washington Technical Park and Metro shall be calculated. 6. Metro shall sign restrictive covenants or to participate in an LID extension of the Valley Parkway from S. W. 7th Street over the P-1 Channel to 400 feet beyond the intersection of Monster Road. 7. Metro will improve Monster Road along Metro's western property line along with a realignment to be approved by the Public Works Department to connect Monster Road to Longacres Drive to a standard of 24 ' wide, 2" Class B asphalt roadway, with improved drainage. This will include minor intersection improvements at the intersection of Longacres Drive and Monster Road. 8. METRO shall prepare a risk analysis of the shipment of chlorine and operation of its proposed chlorination facility as it relates to the City of Renton's disaster plan. This shall include a specific evacuation plan. y is / I i r zo l•_ - 4" ®• is s 5 _ _ V yBAIVDOMED z.rt,,s.f.+ ,tt* v+ q, to f r bUeZr•CT I: ' ' . l' '- ,. 61rE, 1, ,i e k I y'AY c'.>v I•\;• i O.

SHINPOCH MAYOR MEMORANDUM Date: March 4. 1983 To: Dick Houghton Ron Nelson From: Bob Bergstrom Subject: Metro Treatment Plant Expansion The Department of Public Works Engineering Division has many serious concerns with the Metro Renton Treatment Plant expansion project and their lack of addressing City requirements in the phased development. 1.. Internal Plant Fire Protection Metro has an internally-operated water system fed from a single 8" metered supply into their small 10.000 gallon reservoir. The fire flow capacity is unknown and f-ire flow testing is needed to adequately evaluate the fire sys- tem performance. 2. New P-1 Channel Bridge - S.W. 7th St. Extension Metro's new haul route for sludge trucks, via S.W. 7th St. , will make Metro liable for latecomer's fees on the two signalized intersections at (a) Powell and Grady Way and, (b) S.W. 7th and Hardie Ave. S.W. The bridge itself should be open for public access, separate technical plan submittals must be pro- vided, and ramped access down to the future P-1 Channel must be provided. The P-1 Channel should be fully excavated through the bridge area to its final design section. Provisions for future signalization of the S.W. 7th St. and Valley Parkway intersection must be provided, and costs for this signal will be shared between Metro and the neighboring Washington Technical Center development. 3. Monster Road Off-Site Improvements Monster Road must be improved to a 36' wide street - with curb and gutter both sides, storm drainage, street lights- and -sidewalk on one side. 4. Valley Parkway Off-Site Improvements Because of Metro's vague property acquisition plans on their north property line, this requirement's limits of work are not well defined. However, Metro will have to provide 1/2 of the right-of-way and build 1/2 of Valley Parkway along their north plant frontage. Metro Treatment Plant I ion 2 - March 4, 1983 This is a major arterial, four travel lanes, with a two-way left turn center lane, curb, gutter and sidewalk with street lighting and storm drainage. Metro's obligation is for 1/2 of the street improvements. 5. Monster Road - Realignment The south end of Monster Road must be realigned to connect directly into Long- acres Drive S.W. This would_.be a 36' wide road with curbs, gutters, one side- walk and street lighting. This new road would pass through the south edge of the Metro site. 6., Longacres Drive S.W. Off-Site Improvements The north margin of Longacres Drive S.W. , along the Metro frontage must be improved with curb, gutter,. sidewalk and street lighting. 7.; P-1 Channel and Interim Flood Control The flood control issues are very complex and depend in part if the City can bring the Soil Conservation Service back into the project. Metro's present phase will fill an area outside of their present dike. Com- pensating storage should be provided in ;the P-1 Channel right-of-way presently controlled by the City of Renton. The Metro plan for a Flood Water Storage Basin on the north portion of their site is not a recommended option. Metro has deeded the necessary channel rights-of-way, but has not firmly com- mitted to accepting their share of the excavated spoils from the P=1 Channel work. Metro's share of the Phase I P-1 Channel is about 165,000 cubic yards. Previous negotiations have only brought the City some conditional acceptance from Metro to accept their share of this fill . The City- needs' a firm right-of-entry agreement from Metro to move ahead with SCS participation. 8. Haul Route Must be Defined Any earth work hauling for this plant expansion must have a haul route defined. Any hauling into Renton from the Seahurst Tunnel must be defined. 9. Sanitary Sewer Service to North End of Plant Metro has no provision for sanitary sewer service connections from the north end of their plant. While Metro has major internal plant sanitary sewers, they are resisting allowing- connection from the -north-. This- new connection point to service areas to the north from Washington Technical Center, Container Corp. and other developments up Monster Road are required. gb4,Re,„eL, REB:jft V'IEWING DEPARTMENT/DIVISION_!. e l/er r: EIKPPROVED APPIW;ED WITH CONDITIONS L] NOT APPROVED I , ,OE-- e,Jt (---( 4/reAb OF g(.1/L D/Z 6 Ocoosried Cr I. ) WiU.- TCGc zJ,rP ", W Qre R- 5y. , t-1 /ay,'A'oJ/6M Ace°R,oi.66. -ro e-cay..c ac-a,r&- ,e rrUYJ "J rEcT/DN . .5-' ."

Chairman Houghton reported that there would be 47.2% property owners to form an LID in the Grady Way area or 53% which would include Duane Wells (who' s current petition is invalid). He also stated they would contact Mr. Wells and obtain the correct document. Ron Nelson reported that the Building Department had already issued a pre-citation and that the attorney for 0/W Properties had contacted him asking about the next step. Mr. Nelson indicated he would like this matter turned over to the City Attorney for evaluation. Moved by GEISSLER, seconded by CLEMENS to refer to City Attorney. MOTION CARRIED b. Renton Aviation - matter handled under Correspondence. c. Cypress Point Apt. status (continued from June 15th) . Dave Clemens advised that this area had been annexed. Ron Nelson was asked to notify the Agent, Robin Ordonez, of Cypress Point Apts. that he should start street vacation proceedings. d. Steak & Ale Deferral . Moved by CLEMENS, seconded by NORRIS, to advise the Steak & Ale people to close off the parking lot as the deferral had expired. Ron Nelson was asked to write again to Steak and Ale. MOTION CARRIED e. Highlands Community Church - deferral 3/83 (no bond posted). Moved by CLEMENS, seconded by WEBLEY, to put the deferral on hold until such a time as the church makes application for building permit. MOTION CARRIED f. Dennys Restaurant - status. The secretary advised that Rod Parr, architect, had been in talking to Engineering Design trying to bring the deferral and requirements up to date. Board asked that Don Monaghan continue to handle this matter. g. Dr. E. Bennett - status of right-of-way permit and deferral . It was reported that Dr. Bennett had revised his plans, they were approved and there is no longer any need for permit and/or deferral . h. Metro - extension of deferral , 1200 Monster Rd. - status (plans to be submitted within 90 days from 3/23/83) . Moved by CLEMENS, seconded by NELSON, that the Board of Public Works finds that Monster Road is the interim arterial in this vicinity which will be replaced by Oakesdale Drive. As a result the Board finds that improvements beyond street paving for Monster Rd. will not be required. The connection from Longacres Drive to Monster Rd. , and subsequent paving of that section along with paving of Monster Rd. and upgrading of drainage and site distance along the roadway, will be the only requirements.

Dear Mr. Blaylock: Based on recent meetings with Renton City staff, I am submitting . a suggested list of conditions which Metro and the City staff find to be mutually beneficial and equitable for recommending to the hearing examiner for the subject Conditional Use Permit . This letter amends our letter of May 9., 1983, same subject, . and reflects our current position : 1 . Fire protection facilities will meet the City 's code . requirements. This does not include a new loop water main to upgrade the City 's area water system. The existing area water system is adequate to supply fire flows with some modifications to the •on-site system. 2. Southwest 7th Street will be extended westerly to the point of the future Valley Parkway and Southwest 7th Street intersection. and such intersection will be provided along with provisions for future signalization. From the intersection, a culvert type bridge will be constructed over the P-1 channel to the northeast corner of Metro's site to satisfy Metro and the City Fire Department 's preference for site access . Excavation of the .P-1 channel to its design section through the bridge area should not be recommended to the hearing examiner but negotiated as part of the bridge design . Latecomers fees for signal- ization, as discussed in your March 16 , 1983 letter would be paid. 3 . Metro will dedicate one-half of the right-of-way for the Valley Parkway and improvements along the northern site property line . F', y ...'

As an alternative to numbers 2 and 3 above , Metro has no objection to possible participation in an LID to extend Southwest 7th Street to the intersection of the. future Valley Parkway and then northerly and westerly over the P-1 channel to 400+ feet beyond intersectingMonsterRoad. It has been Metro's' frequent practice in other locations to cooperate in the 'LID process. Of course, Metro staff cannot make a commitment to an LID; the commitment must come from the Metro Council after it- has had an opportunity to review the petition. . We look forward to working with the City to further define the scope of the LID petition, particularly with respect to the reasonableness of Metro's ultimate cost obligation. 5. Monster Road will be improved along Metro's west propertyline . Improvements include a 24 ' wide, 2" class B asphalt roadway with improved drainage and site distance. 6. Monster Road would be realigned to intersect with Longacres Drive . Metro would provide approximately 50% of the 60 ' . right-of-way and extend the Monster Road 24 ' wide, 2" class B asphalt roadway with drainage to Longacres Drive . Metro would be allowed access to this roadway.Minor intersection improvements would be included, 1however, no other improvements to Longacres Drive would be provided. This commitment is contingent upon developing a reasonable and equitable- right-of-way plan with the neighboring property owner and the' results of more detailed design in coordination with the City.. 7 . Metro has started excavating the P-i. channel.. in accordance with the Cit"'s preference for provision of compensatingfloodstorage . As a result , Metro will deposit approxi- mately 50, 000 cubic yards of spoils.. on-site . We will honor our past commitment to take 99 ,000 cubic yards, or an additional 49 , 000 cubic yards of spoils . We will also continue to work with the City to accommodate spoils on-site in addition to the remaining 49 ,000 cubic yards . We would prefer to implement the improvements along with construction of the IIC - Solids Handling facilities scheduled for advertisement in the Spring , 1984 .

Metro has reviewed the City' s letter which, .out- lines conditions that the City departments may recommend to, the Land Use Hearing Examiner concerning the subject permits. We would like to ensure that this response and past Metro correspon- dence is entered into the hearing examiner' s file for his review prior to the hearing. In addition, we request a-meeting with:Mr. Houghton, Mr.. Nelson, Mr. Geissler and the Mayor prior to the formulation of final recommendations by the City departments to discuss several problems outlined below. Generally, Metro is concerned that the list of improvements recommended by the City are excessive, appear to lack legal . authority and are disproportionate to the impacts caused by the plant enlargement. It is difficult to assess the legal grounds. for many of the City' s proposed conditions since no response was provided to my request for clarification on this matter. Metro understands that the City may attach reasonable conditions to the granting of a conditional use permit, and Metro is willing to: cooperate with the City, in, a mutually beneficial effort to upgrade the' vicinity streets. However, those conditions must;'be reasonably related to the plant enlargement' s impact on its surroundings and cannot be imposed arbitrarily. We estimate that the improvements suggested by the City could cost Metro up to°-- 2.5 million. In reviewing the suggested street improvements, we have been unable to find a comprehensive plan for upgrading the traffic circulation problems in the vicinity of the plant. Where plansdoexist, it seems that some of your suggested improvements are inconsistent. For example, your request for Metro to provide one-half of the Valley Parkway right-of-way and improvements p CrJ(;r.

'past traffic plans but suggests a horizontal alignment which is technically undesirable.

We believe that theMwideningl of Monster Road to 36 feet with curbs and gutters on both sides, storm drainage, street lights and sidewalks on one side is un- justified. We also question the legal authority for imposing improvements on more than one-half of the street. We believe 15 that the public benefits of this extensive work, at an estimated cost of $375,000 , are at best dubious. Since the future Valley Parkway will be the major arterial in the area and Monster will be a secondary collector, Metro suggests that a better solution would be to reduce the requirement to at 24 foot-wide new asphalt road with some improvement to the sight, distance problems. Further, we believe that a reduction in this requirement could include a condition that Metro work with the City on realigning Monster Road, which is discussed below. Finally, we believe the City should explore with some vigor the possibility that adjoin- ing landowners assist with the Monster Road improvement. Valley Parkway Off-Site Improvements. Because of the vague alignment of the Valley Parkway and because the Valley Parkway is a general improvement in the area, we. believe that Metro should not be obligated to provide one-half of the right-of-way and a improvements. As previously discussed, it appears that the City' s current street plan calls for the Valley Parkway to be aligned in a location_ that would not require the use of Metro property. ,An alignment along one-half of Metro' s northern property also appears to be technically undesirable. If Metro decides to abandon the P-1 channel bridge access, the Valley Parkway would have no direct benefit to Metro, nor would Metro' s presence impact the Parkway in a significant way. The Valley. Parkway has been planned for sometime, and therefore, the plant enlargement should not be construed as impacting the need for this street improvement. This suggested condition is estimated to cost $210,000 , without land costs included. Monster Road Realignment. We believe that the City has no valid legal grounds for recommending such a condition. It is difficult if to identify the City' s design goal for such a suggested street improvement since no specific street plan is available. We are S particularly concerned about this condition because it could result in severance to property which we are presently negoti- ating a purchase. The property has an irregular shape with power line easements, making it difficult to develop without the complication of realigning Monster Road. However, we are willing to work with the City staff on developing a realignment project, provided that the City is willing to negotiate with the neighbor- ing property owner to the south for additional right-of-way and that a traffic plan be developed to minimize impacts to Metro from Longacres traffic. We foresee this improvement as an I( Cf[/Cf r..'. i t i EJil,rg 8 2.-.-2 C::t )IT11Mr. Roger Blaylock d 1;`L u,, 7L i li) May 9 , 1983 Page 4 MAY 1 1 '198 extension of the 24 foot-wide asphalt upgrade to Monster Road. We estimate the suggested improvement to cost up to $103,000 without land costs. Longacres Drive S.W. Offsite Improvement. Metro is in the process of negotiating with Burlington Northern for the purchase of property which is described as "Metro frontage" in your letter. A purchase agreement could take at leastsix months to consummate, if at all. Even if we succeed in acquiring the property, we question the reasons for curbs, gutters and lighting along this segment of roadway. Estimated cost is $27,000. P-1 Channel and Interim Flood Control. Metro has cooperated with the City for providing flood control in the P-1 Channel in con- junction with our site preparation contract rather -than excava- 7 ting a storage basin as originally planned. The site preparation contract has been awarded and the cost to Metro is based on the bids received: $216 ,000 for the P-1 channel versus $86,000 for the storage basin for. a net cost to Metro of $130,000. In regard to firm commitments for accepting P-1 channel spoils, evidence from past correspondence indicates that Metro m_ ade : a commitment to the City for accepting. 99 ,000' cubic yards of spoils from the P-1 channel. About six months ago, the City informed Metro that our share had increased to 150,000 cubic .yards and then, more recently, to 165,000, due to the recent purchase of property. We do not understand how Metro' s "share" can increase by 65% when the recent land purchase amounts to about a 16% increase® It seems that the definition of "share" is being construed loosely and that the methodology for distributing 165,000 cubic yards of P-1 channel spoils to Metro should be re-: viewed for its equity. Metro will be disposing of approximately 50 ,000 cubic yards of spoils on its property as a result of the P-1 channel excavation work discussed above. Based on the past "commitment" , we are obligated only to accept 49 ,000 cubic yards' more. We have stated. to the City in recent correspondence that Metro would -be willing to negotiate the acceptance of even more spoils from the P-1 " channel, but that requiring the increased quantity is unaccep- table. We cannot be put in a position of giving the City an open ended" obligation for disposing of P-1 channel spoils. We will need to specifically define fill elevation constraints on our property and to have agreed-upon time constraints from the City before we can commit to accepting additional fill. Addi- tional fill requirements cannot be imposed unilaterally; to do so raises a question whether Metro and the City even have an agreement" at all. 0 C211CC-I Mr. Roger Blaylock May 9 , 1983 Page 5 MAY Haul Route Must be Defined.

Sanitary Sewer Service to the North End of Plant. Metro is not,. obligated to provide local sewerage collection, particularly fromtheinternalplantsystem. The internal plant system was designed to allow surcharging, which would result in sewage flooding below certain elevations- off-site.- Therefore no connec- tion can be allowed. There is a 12-inch stubout in the junction structure of the southside and eastside interceptors that the service area to the north could utilize if in accordance with your approved local comprehensive' plan.

Renton Treatment Plant Enlargement Dear Mr . Bergstrom: Based on progress made with the City of Renton concerning approval of the grading license , Metro is anticipating that Schedules #1 (Base Bid ) and #3 (P-1 Channel) of the Site Preparation contract will be awarded . Since we are opening bids on April 5 , 1983 , I would like to confirm my understanding of the City ' s position on the. following items based on past discussions with you and other City staff. 1 ) In order to relocate the existing flood dikes around the Renton Treatment Plant as proposed , Metro is required , by regulation, to provide compensating flood storage.. Our original proposal in meeting this requirement was to excavate 27 , 000 cubic yards from our property to the north of the proposed dike . An alternative proposal desirable to. the City and Metro is to excavate the P-1 Channel which involves excavating approximately 50 ,000 cubic yards. or 23 ,000 additional yards than originally anticipated. It is our understanding that the City will allow Metro credit for the equivalent cubic feet of flood storage that the additional 23,000 cubic yards of excavation represents in the event Metro wishes to place fill on its property in the future within the FEMA designated flood area . 2) Metro has a past . commitment to the City that it will . allow approximately 100 , 000 cubic yards of spoils from the P-1 Channel project to be disposed on, the Renton Treatment Plant property . If bid schedule No , 3 is awarded , approximately 50 , 000 cubic yards of P-1 Channel material will be excavated by Metro and disposed of on the Renton Plant property . Recently the City of Renton v dY.;?9. eggr4 f Ait#n l'i%^':MV4 S#:s' b.. 7 i,c5T.'.N-"'h L Mr . Robert Bergstrom March 29 , 1983 Page Two has requested that Metro accept an additional 65 ,000 cubic yards of spoils from the P-1 Channel . We are willing to cooperate with you on disposing of P-1 Channel spoils on the treatment plant property . However , our ability to make a commitment must be predicated on the timing of the P-1 Channel project and of Metro 's plans to enlarge the Renton Plant in the future. Metro cannot commit to accepting the additional 65, 000 cubic yards at this time without a firm schedule for construction of the P-1 Channel and without full knowledge of future construction impacts on the site . Therefore , it is my understanding , based on our previous discussions , that the City will be flexible on this issue . 3) Metro has recently proposed to the City that an existing Washington Natural Gas (WNG) gas main within Metro' s property be relocated into the proposed P-1 Channel maintenance road . WNG has tentatively approved the proposed location which would require an easement . The easement would be in the maintenance road from a position near the southeast to a position near the northeast corner of Metro ' s property . You stated that the City has title to the property and can execute such an easement within the subject property. You also indicated that the City, in general , has no problem with the proposed alignment . I will contact you in the near future to arrange a meeting between the City and WNG to discuss the technical and right-of-way aspect in more detail. Thank you for your cooperation . Unless we hear from you by April 4 , 1983 , I will assume that the preceding statements reflect the City ' s position. Very truly yours , 14714441144114 avid G.

Hammond Project Manager Municipality of Metropolitan Seattle Exchange Building 821 Second Avenue Seattle, WA 98104 Re: Annual Grading License/Metro Sewage Treatment Plant Dear Mr. Hammond: The Building and Zoning Department has reviewed the proposed filling and grading activities of the proposed expansion of the Metro Sewage Treatment Plant. These activities are within the scope.of the original special permit issued to King County Public Works Department concerning the excavation and storage of fill materials surrounding the Phase 1, East Side Watershed Project. The City has just issued a, Shoreline substantial development permit for the same work to construct the P-1 Channel and detention pond (copy enclosed) which would allow Metro to conduct their filling and grading activities according to their time schedule. The Shoreline's permit was mailed to the State of Washington on Tuesday, March 15. We expect receipt and approval by the end of April, 1983. This would allow a May 1 startup date for your excavation and filling operations. Under the City of Renton's Mining and Grading Ordinance, the Building and Zoning Department processes an annual license to assure that the contractor is complying with the intent of a special permit. Forms have already been sent to you for completion and resubmittal. It is anticipated that this license can be issued immediately upon approval by the Department of Ecology of the substantial development permit. This application should be presented to our department as soon as possible to allow adequate processing prior to issuance.

Hammond Project Manager Municipality of Metropolitan Seattle Exchange Building 821 Second Avenue Seattle, WA 98104 Re: Expansion of Existing Wastewater Treatment Plant/Metro Special Permit SP-006-83 and Conditional Use Permit CU-007-83 Dear Mr. Hammond: The City of Renton offers the following preliminary suggestion of conditions that the various City departments will recommend to the Land Use Hearing Examiner concerning the conditional use and special permit applications. These conditions have been reviewed and accepted by the Environmental Review Committee without a statement of lead agency status or as items of environmental mitigation. The City's present position is that if the applicant is willing to modify their conditional use project to include these items, then the City will not undertake the dispute over lead agency status. Internal Plant Fire Protection: Metro has an internally-operated water system feed from a single 8" meter supply into its small 10,000 gallon reservoir. The fire flow capacity is unknown and fire flow testing is needed to adequately evaluate the fire system performance. It is the City's intent that if the system needs to be upgraded, then.Metro shall provide that as part of their total improvement proposaL New P-1 Channel Bridge - S.W. 7th Street Extension. Metro's new haul route for sludge trucks, via S.W. 7th Street, will make Metro liable for latecomers fees on two of the signalized intersections at (a) Powell Avenue S.W. and S.W. Grady Way and, (b) S.W. 7th and Hardy Avenue S.W.. The extension of S.W. 7th Street via the bridge will be a cost borne solely by Metro for its access to the northeast corner of the subject site. The bridge itself should be open for public access, separate technical plan submittals must be provided, and ramped access down to the future P-1 Channel must be provided. The P-1 Channel should be fully excavated through the bridge area to its final design section. Mr. David G. Hammond March 16, 1983 Page 2 Provisions for future signalization of the S.W. 7th Street and Valley Parkway intersection must be provided, and cost for this signal will be shared between Metro and the neighboring Washington Technical Center development. Monster Road Offsite Improvements: Monster Road must be improved to a 36' wide street - with curb and gutter on both sides, storm drainage, street lights and sidewalk on one side. The issue of whether these major improvements on Monster Road should be shifted to the Valley Parkway is an issue which can only be resolved by the Board of Public Works in considering a deferral or waiver of the required improvements to Monster Road. Prior to the Board of Public Works making a decision, Metro and the Department of Public Works should make a formal agreement as to the specific improvements. Valley Parkway Offsite Improvements: Because of Metro's vague property acquisition plans on their north property line, this requirement's limits of work are not well defined. However, Metro will have to provide one-half of the right-of-way and build one-half of the Valley Parkway along their northern plant frontage. This is a major arterial, four travel lanes, with a two-way left turn center lane, curb, gutter, and sidewalk with street lighting and storm drainage. Metro's obligation is for one-half of the street improvements. Monster Road - Realignment: The south end of Monster Road must be realigned to connect directly into Longacres Drive S.W. This would be a 36' wide road with curbs, gutters, one sidewalk and street lighting. This new road would pass through the south edge of the Metro site. Longacres Drive S.W. Offsite Improvements: The north margin of Longacres Drive S.W., along the Metro frontage, must be improved with curb, gutter, sidewalk and street lighting. P-1 Channel and Interim Flood Control: The Flood control issues are very complex and depend in part if the City can bring the Soil Conservation Service back into the project. Metro's present phase will fill an area outside of their present dock. Compensating storage should be provided in the P-1 Channel right-of-way presently controlled by the City of Renton. The Metro plan for flood water storage basin on the northern portion of their site is not a recommended option. Metro has deeded the necessary channel right-of-way, but not firmly committed to accepting their share of the excavated spoils from the P-1 work. Metro's share of the Phase 1 P-1 Channel is about 165,000 cubic yards. Previous negotiations have only brought the City some conditional acceptance for Metro to accept their share of this filL Mr. David G. Hammond March 16, 1983 Page 3 The compensating storage site which was originally planned along the northern property line could accommodate much of the necessary 165,000 cubic yards of dredge debris. The City needs a firm right of entry committment from Metro to move ahead with SCS participation. Haul Route Must be Defined: Any earthwork hauling from the plant expansion must have a haul route defined. Any hauling into Renton from the Sea-First Tunnel must be defined. Sanitary Sewer Service to North End of Plant: Metro has no provisions for sanitary sewer service connections from the north end of their plant. While Metro has major internal plant sanitary sewers, they are resisting allowing connection from the north. This new connection point to the service areas to the north from Washington Technical Center, Container Corporation and other developments up Monster Road are required. Supplemental Environmental Analysis: Additional detailed analysis of truck traffic from the sludge disposal and odors and visual impacts from solids handling need to be addressed prior to the public hearing. Specifically the issues of volume of traffic, route, size of vehicles, and potential for hazardous waste from industrial users should be evaluated. The above suggestions relate a specific review point of the City of Renton staff concerning the expansion of the Metro Treatment Plant. Several of the items appear to be very minor in scope and probably within the design parameters of your existing proposaL On the other hand, some of the issues need specific negotiation between the City and Metro either at the time of the conditional use permit or as a modification to the application. These conditions represent a minimum necessary modification to the proposal as seen by the City of Renton to be acceptable and compatible with community policies and directives.

During that meeting we discussed many aspects of the project including requirements and desires of the City of Renton for other improvements in conjunction with the treatment plant enlargement . I would like to address these points and provide some clarifi- cation by topic . 1 . Flood Control : Metro will be required to excavate approxi- mately 27 , 000 cubic yards of material on its own property adjacent to the P-1 channel at a cost of approximately 102 , 000 in order to provide compensatory flood storage for relocating the existing dikes . Alternatively, it is the City 's desire and Metro agrees that excavating approximately 60 , 000 cubic yards of material from the P-1 channel under the City ' s direction for an approximate cost of $220, 000 would be more beneficial . We will need written assurance that ; ( 1 ) the provision of this flood storage will allow Metro to raise the contours of all its land for its own future development within the existing land proposed property boundaries without any further flood storage requirements ; and ( 2) the requirement to accept over 40 , 000 cubic yards of additional spoils from the P-1 channel would be negotiable . We would also like the City ' s approval to relocate the WNG ' s gas pipeline from the eastern boundary of Metro 's property into the P-1 channel maintenance road . The easement would need to be within the maintenance road and extend from a position near the southeast corner to a position near the northeast corner of Metro ' s property . We believe the mutual benefits which accrue to the City , Metro and adjacent property owners off-sets some of the additional expense to be borne by Metro. We also believe that a portion of these additional costs should be considered as credit against any City requirements for other improvements . rF: ` ..• .;o''; - '7`` • '•• '1".sx .,4 _ ;jR '+t,. _ -.,R Mr . Richard Houghton March 8, 1983 Page Two 2. Transportation/Traffic: a . As you recall, we discussed that there was not much sense in upgrading Monster Road to City standards because the "future Valley Parkway is planned to be the major arterial in the area and Monster Road a secondary roadway. Therefore, minimal upgrade (resurfacing) to Monster Road would be sufficient and that the Valley Parkway should be the focus of future roadway investments . b. We also discussed the proposed site access from 7th Street to the northeast corner of Metro 's property. Metro desires but does not require this access . It was noted that this access was proposed as a result of past discussions between Metro and the Renton City Fire Chief and in accordance with your access regulations for industrial. properties . Metro also desires an alternative site access for employees and sludge hauling. As a point of clarifi- cation, Metro would be willing to participate in the future Valley Parkway to the extent required and to the extent that the Valley Parkway benefits Metro . Again, Metro ' s total commitment to the Valley Parkway would have to be related to a direct legal requirement, reduction in other requirements and credit for the 7th Street and Valley Parkway connection/intersection. c . Metro would be willing to participate in area signali.- zation that would benefit us as discussed . d . Metro is willing to discuss the City's desire to tie Longacres Drive directly to Monster Road . However, the proposal you presented at the meeting concerns us and we are totally opposed to dedicating existing or future Metro property you identified for street right-of-way . We are willing to discuss it further once we receive a more detailed proposal from you . Again , your proposal would have to be considered in light of other improvements the City requires . . f.' b T Mr. Richard Houghton March 8, - 1983 Page Three Metro is willing to cooperate in implementing improvements which are requirements by the City's laws and regulations. We look forward to receiving your written comments pertainingtotheconditionaluseandgradingpermitapplicationsand appreciate your willingness to expedite the grading permit application .

RENTON TREATMENT PLANT ON-SITE EXPANSION ENVIRONMENTAL PROCESS IN COMPLIANCE WITH SEPA The environmental impacts of the Renton Treatment Plant on-site expansion are addressed in the enclosed Final Environmental Impact Statement (EIS) on the Wastewater Management Plan for the Lake Washington/Green River Basins, issued in August 1981. The EIS was prepared by EPA concurrently with facility planning studies undertaken by Metro beginning in 1979. The Plan recommended expansion of the Renton Treatment Plant to 72 million gallons per day capacity and construction of on-site solids handling facilities. The EIS was prepared under the National Environmental Policy Act (NEPA) , and was intended to allow necessary decisions on the plan by agencies with jurisdiction, including EPA, Metro and the Department of Ecology (DOE) . Metro subsequently adopted this NEPA EIS in lieu of a separately prepared SEPA EIS as allowed by WAC 197-10-650 (1) . Metro is acting as lead agency on all parts of the Renton Improve- ment Program for compliance with SEPA, consistent with WAC 197-10-205. The Draft and Final EIS' s were previously supplied to the City of Renton for review and comment. The EIS is enclosed with the current applications for permits for use by the City of Renton in issuing the permits, consistent with WAC 197-10-690 (1) .

FROM: DAVID HEALEY, SEATTLE SUBJECT: MINUTES OF MEETING--AUGUST 5, 1982--CITY OF RENTON Attendees Warren Uhte Brown and Caldwell Dave Healey Brown and Caldwell Ray Drebin Municipality of Metropolitan Seattle (Metro) Dave Hammond Metro Building and Zoning Department, City of Renton Gary Norris Public Works Department, Renton Tom Binghaman Renton Police Department Cliff Bates Street Department, Renton Purpose: Discuss site access alternatives for sludge hauling trucks and drainage requirements for relocating existing dikes. 1. Warren Uhte briefly described the proposed solids processing facilities at the Renton plant and what this will mean in terms of large semi-trailer truck traffic leaving and entering the plant each day. Three alternatives access routes were pre ented: Alternative A--Connection to Southwest 10th Street Alternative B--Connection to Grady Way Alternative C--Connection to Longacres Drive 2. It was agreed that Alternative A was the best alternative since there will be a signalized intersection at Powell and Grady Way. It was brought out that the Grady Way Bridge has a weight limit of 15 tons, which will prohibit sludge trucks carrying 26 tons of wet sludge from using this bridge. . This bridge is scheduled to be renovated within 2 or 3 years according to city personnel. 3. Ron Nelson said that it is very likely there will be a drainage channel as planned. Therefore, a bridge will be required for Alternative A. Files August 23, 1982 Page two 4. The Powell and Grady intersection is being financed in part by property developers. Nelson believes that if Metro uses this intersection, the developers may want some Metro partici- pation. 5. Desirability of a connection to Monster Road around the north end of the plant is still in the planning stages. Developers to the north are required to make a tie to Empire Way. 6. Puget Power may develop some property along Grady Way; Metro might approach Puget Power about participation in the roadway. 7. Warren Uhte described proposed changes to the existing dikes. Relocation would remove approximately 9. 9 acres from potential used for floodwater storage. There would be sufficient Metro property outside the dikes to compensate for lost storage by excavating approximately 7 .4 acres to a depth of 3 feet. It was further expalined that at ultimate development all surface runoff from the plant will be diverted to the Green River. 8. City personnel saw no problem at this stage, but suggested that Brown and Caldwell provide full documentation when presenting this proposal to the City Council. 9. Nelson said that if the c} annel is constructed the foot3 storage volume per 1 foot' developed area requirement may not have to be provided. This will be decided by the Director of Public Works or other officials. 10. Drebin replied that the timing of channel and plant construc- tion may be such that Metro would have to provide the addition- al storage. 11. The city will supply information on bridge standards and development requirements. DH:cp cc: P. Anwar Seattle W.

Notary Public in and for the State of Washington, residing at PAGE 3 OF 3 PAGES fmE RD Municipality of Metropolitan Seattle Exchange Bldg. • 821 Second Ave.,Seattle,Washington 98104- September 27 , 1983 Mr . Jim Hanson City of Renton Building and Zoning Department 200 Mill Avenue Renton , Washington 98055 Renton Treatment Plant Enlargement : Status of Conditional Use Permit Requirements Dear Mr . Hanson : The purpose of this letter is to respond to the City of Renton 's staff request concerning Metro ' s plans for implementing the eight (8) conditions outlined beginning on Page 7 of the City ' s conditional use permit No . METRO : CU-007-83 . The City has requested this information in conjunction with Metro 's applica- tion for a building permit for the Renton Treatment Plant Enlargement IIB - Liquid Stream. This letter is also a follow-on to our letter of June 6 , 1983 (attached ) , and our responses to the hearing examiner at the hearing of June 28, 1983 documented on Page 3 of the conditional use permit . To refresh your memory, the conditional use permit was issued in regard to the $123 million Renton Treatment Plant Enlargement project which is a phased construction program composed of the following contracts : Start Completion Phase Date Date IIA - Site Preparation May 1983 Sept . 1984 IIB = Liquid Stream Enlargement Sept . 1983 Jan . 1986 IIC - Solids Stream July 1984 June 1987 IID - Computer Automation May 1984 June 1987 IIE - Plantwide Landscaping , Spring 1986 Sept . 1987 Mr . Jim Hanson City of Renton September 27 , 1983 Page Two This project is a joint effort by the State Department of Ecology and Metro and the funding has been secured . Because of the fast-track nature of this project it has been Metro 's intent to implement most of the City 's conditions during construction of the IIC - Solids Handling facilities . This was previously discussed with City building and public works officials and outlined in our June 6th letter with no objection previously raised by the City . The following is the status of our efforts to implement the eight (8 ) conditions outlined in the conditional use permit : Condition #1 : The applicant provide affirmation that the Metro Council will permit Metro to participate in an LID which may be created to construct , improve or build the Valley Parkway Oaksdale Road ) . Response : As stated by our June 6th letter , Metro has no ojec- tion to possible participation in an LID to extend S .W. 7th Street to the intersection of the future Valley Parkway and then northerly and westerly over the P-1Channel to 400 + feet beyond intersecting Monster Road. It has been Metro 's frequent practice in other locations to cooperate in the LID process as long as the ultimate cost obligation to Metro is equitable . We are presently exploring what action must be taken by the Metro Council to comply with this condition since the City has not filed a petition. We will coordinate with the City in this regard . Condition #2 : Metro shall be responsible for the construction of a bridge and roadway over the P-1 Channel in the general vicinity of S.W. 7th Street . Such construction shall be completed prior to the receipt of the first chlorine tank car on the subject site . The road shall include all necessary improvements as determined by the Public Works Department , including signalization for which the applicant will be responsible for a reasonable pro rata share . Mr . Jim Hanson City of Renton September 27 , 1983 Page Three Response : Per our June 6th letter and response at the hearing , Metro has always planned and originally proposed providing access to the eastern portion of the plant property via S.W. 7th Street and a bridge over the P-1 Channel to the northeast corner of Metro 's site . Although not specifically required above , Metro plans to extend S .W. 7th Street from its present terminus westerly to the point of the future Valley Parkway and S .W. 7th Street intersection along with provisions for future signalization . In a recent meeting with the Public Works Department , we were informed that the City only had a roadway easement and not a utility easement . We will continue coordinating with the City Public Works Department to determine the roadway requirements . It is our intent to provide access to Metro ' s property as discussed above in conjunction with our next construction contract , IIC - Solids Handling . Condition #3 : Metro shall improve the alignment of Monster Road along the western boundary of the subject site , including the intersection of Monster Road and Longacres Drive . Response : Monster Road will be improved along Metro ' s west property line . Improvements include a 24 ' wide , 2" class B asphalt roadway with improved drainage and site distance . Monster Road would also be realigned to intersect with Longacres Drive . Metro would provide approximately 50% of the 60 ' right-of- way and extend the Monster Road 24 ' wide , 2" class B asphalt roadway with drainage to Longacres Drive . Metro would be allowed access to this roadway . Minor intersection improvements would be included , however , no other improvements to Longacres Drive would be provided . This commitment is contingent upon developing a reasonable and equitable right-of-way plan with the neighboring property owner and the results of more detailed design in coordination with the City . Metro is presently working with the Public Works Department to refine the design of these improvements for inclusion in the IIC construction contract . Condition #4 : The applicant shall dedicate one-half ( 2 ) of the right-of-way for the Valley Parkway between the P-1 Channel and Monster Road . Mr . Jim Hanson City of Renton September 27 , 1983 Page Four Response : Metro will dedicate one-half ( 2 ) of the right-of-way for Valley Parkway within its property between the P-1 Channel and Monster Road . This will be accomplished prior to obtaining a building permit for the IIC construction phase . Condition #5 : Metro may seek latecomers agreements as determined by the City Council for any aspect of roadway improvements . Response : No comment . Condition #6 : The applicant will prepare a risk analysis of the chlorine tank car operation and will coordinate with the Police and Fire Department to provide for an evacuation plan for the area in the event of any chlorine leak . Response : Metro is presently preparing a risk analysis and emergency evacuation plan which would be submitted to the City for review in January , 1984 . Condition #7 : The fire flow system provided by the applicant shall be subject to the approval of the Fire Department . Response : The Fire protection system to be provided by Metro will comply with the City ' s code requirements . We have been working with the City to establish the required fire flows . We will continue to work with City officials to determine flow requirements and alternative facilities to meet the requirements during the IIC project phase . These facilities would be completed prior to occupancy of the IIB facilities (aeration and sedimentation tanks , gallery and chlorine building) . Condition #8 : Landscaping as approved by the City of Renton Landscape Architect . Response : A landscaping plan has been submitted to the building department . Plans and specifications for final plantwide land- scaping is expected to be awarded in the Spring of 1986 . As a public agency , Metro shares your concern for the health and safety of the public . We are presently working with the City to implement these conditions stated above by no later than the IIC construction contract . This contract will be submitted to the City along with a building permit application in February , 1984 , for the City 's review. We expect to comply with Mr . Jim Hanson City of Renton September 27 , 1983 Page Five these conditional use provisions at that time . With the overlap of the IIB and IIC contracts , we can ensure that any requirements applicable to IIB can be implemented in a timely fashion . Upon submittal of this letter , it is our understanding that a foundation permit will be issued and ultimately a building permit . We expect that the City will cooperate with Metro on the implemen- tation of this mutually beneficial project . The treatment plant flows are now exceeding the design capacity and it is important that we proceed as soon as possible . Our schedule must be maintained to enable us to meet our legislative mandate . Because of the dynamic nature of this project , we would like to propose that a joint Metro and City of Renton management level project review committee be established . We would propose that the committee include the Directors of Public Works , Building and Zoning, the Fire Department Chief representing the City , and project management representatives from Metro . Further , we would propose meeting in the next two (2 ) weeks to discuss this proposal . Thank you for your attention to this matter and look forward to your assistance on this project .

It has undergone an in-depth study by METRO, D.O.E. and EPA. This project coordinates very closely with the development of the P-1 Channel, which was granted a Shoreline Substantial Development Permit (SM-93-81) in April of 1982. In actuality, METRO will begin the construction of the first phase of the P-1 Channel. Enclosed are both the staff reports and Land Use Hearing Examiner decisions related to the project. I have only enclosed reductions of the design plans because of the bulk of the scale drawings. We anticipate some minor revisions in the engineering of these plans, but no major changes in layout of the plant or basic design. I am sure that you are aware of the critical nature of the expansion of the sewage treatment plant. This facility is presently operating over design capacity and represents a major environmental threat if it failed. This Shoreline Substantial Development Permit does not include the proposed tunnel from the site to Puget Sound. The City of Renton considers this a separate and distinct issue. Thank you very much for your time. If you have any questions, please call me at (206) 235-2550. Sincerely, CYTB(61( 41 Roger J. Blaylock Zoning Administrator RJB:se Encl.

CU-007-83 Municipality of Metropolitan Seattle LOCATION: 1200 Monster Road S.W. SUMMARY OF REQUEST: Applicant seeks approval of a conditional use permit to allow the expansion of the sewage treatment plant in a G-1 Zone. SUMMARY OF ACTION: Building and Zoning Department Recommendation: Approval, subject to conditions. Hearing Examiner Decision: Approval, subject to conditions. BUILDING & ZONING The Building & Zoning Department Report was DEPARTMENT REPORT: received by the Examiner on June 21, 1983. PUBLIC HEARING: After reviewing the Building and Zoning Department Report, examining available information on file with the application and field checking the property and surrounding area, the Examiner conducted a public hearing on the subject as follows: The hearing was opened on June 28, 1983, at 10:05 a.m. in the Council Chambers of the Renton Municipal Building: Parties wishing to testify were affirmed by the Examiner. The following exhibits were entered into the record by the Hearing Examiner: Exhibit #1: Yellow file containing the application, letter dated June 6, 1983 which substantially revised the application, and other pertinent documents. Exhibit #2:General vicinity map showing the subject site. Exhibit #3: Specific site plan map. Roger Blaylock, Zoning Administrator, presented the staff report. He indicated METRO is preparing an environmental impact statement on the tunnel and pump plant; consequently, that should be excluded from this conditional use permit and would require a supplemental permit for that portion itself. With the development of the plant, there would be continued growth in the region. It was pointed out that there would not be major operational truck traffic; the two operational points seen by staff would be the exiting of solids from the northeast corner of the site and the servicing of septic pump stations. Mr. Blaylock then reviewed the site plan map. Testifying at this point was: David Healey Brown & Caldwell 100 W. Harrison Street Seattle, WA 98119 Mr. Healey stated there will not be any new primary treatment facilities under this expansion, only secondary treatment facilities. METRO: CU-007-83 Municipality of Metropolitan Seattle July 12, 1983 Page 2 Mr. Blaylock reported that there will be tank cars of liquid chlorine; the building is designed to handle two chlorine tanks or the interchanging of two chlorine tanks stationed in the building. Solids will be taken out to appropriate dump sites such as fertilizer projects, farming activities, etc. The Examiner asked if the structures to the north would be below the flood level or above. Mr. Blaylock indicated they would be above flood level. Mr. Healey explained their method of measuring sea level, which is starting with an elevation of 100 for mean sea level because there are some structures that are below sea level. The Examiner asked what that means to the city as far as their flood storage capacity is concerned. Mr. Healey indicated the dike will be moved out on the east side to approximately the property line and on the North side to just north of the digesters. Mr. Blaylock pointed out that the development will require the construction of a culvert type bridge across the P-1 Channel to the northeast corner of Metro's present site and creates a new primary operational access to the site and will be utilized for sludge truck hauling in the future; further, it provides a faster emergency access for fire equipment. Mr. Blaylock noted that reference is made to Valley Parkway in the staff report on page 5, Item 8, and that should be amended to reflect Oakesdale instead of Valley Parkway. Further, that Metro has indicated they would not object to participation in an L.I.D. to extend S.W. 7th, which would actually be the Parkway, from S.W. 7th over to Monster Road; the problem they have at this time is that their staff can say they will recommend this to the Metro Council, but Metro Council must make the final decision. The other option they could have is that through dedication, they could improve, and the city could then come back and grant a latecomers agreement to Metro. The Examiner inquired how often the tank car of chlorine would be changed per year. Mr. Healey indicated that it would be once every two months initially; once at design capacity, it would probably be once a month. However, he stated that the chlorine is now being brought in every two weeks because of the reduced capacity for storage. The Examiner then questioned whether the anarobic digesters would be a problem in the area. Mr. Healey advised that generally they are not if they are operated properly and not overloaded; that every effort will be made to keep odors to a minimum. Mr. Blaylock closed his report by indicating that the staff recommends approval of the conditional use permit, subject to the following eight (8) conditions: 1. Approval of an appropriate fire protection system meeting the City of Renton's code requirements by the Fire Department. 2. Construction of S.W. 7th Street from its existing completion point at Washington Technical Center to the subject site. Construction will include the intersection at the Parkway and S.W. 7th Street with provisions for future signalization. 3. Construction of a culvert-type bridge over the P-1 Channel to the N.E. corner of Metro's site, to include and be approved by the Public Works Department. The Public Works Department shall be granted full authority to determine whether the excavation of the P-1 Channel to its designed section through the bridge area should be required. This item should not be appealable to either the Hearing Examiner nor the City Council because the City has previously approved the necessary design configuration for the P-1 Channel. 4. Metro shall dedicate one-half of the right-of-way for the Parkway and its improvements along the northern property line. This dedication shall be a minimum of 40 feet in width to comply with the needs of an industrial collector arterial. 5. Metro shall signalize the intersection at S.W. 7th Street and the Parkway at the time determined by the Board of Public Works. This may correspond with the development of Phase 2 or Phase 3 of Washington Technical Park. At that time, a proportionate share between the developers of Washington Technical Park and Metro shall be calculated. r METRO: CU-007-83 Municipality of Metropolitan Seattle July 12, 1983 Page 3 6. Metro shall sign restrictive covenants or to participate in an LID extension of the Valley Parkway from S.W. 7th Street over the P-1 Channel to 400 feet beyond the intersection of Monster Road. 7. Metro will improve Monster Road along Metro's western property line along with a realignment to be approved by the Public Works Department to connect monster Road to Longacres Drive to a standard of 24' wide, 2" Class B asphalt roadway, with improved drainage. This will include minor intersection improvements at the intersection of Longacres Drive and Monster Road. 8. Metro shall prepare a risk analysis of the shipment of chlorine and operation of its proposed chlorination facility as it relates to the City of Renton's disaster plan. This shall include a specific evacuation plan. The Examiner called on the applicant or representative. Testifying was: Susan Solberg Metro Municipality of Metropolitan Seattle 821 - 2nd Avenue Seattle, WA 98104 Ms. Solberg indicated that everything explained to her by Mr. Blaylock had been explained adequately and that with reference to the conditions, she offered the following comments: Condition #1: No problem with this. Condition #2: No problem with this, but they would ask that the Council consider a latecomer's agreement for other property owners for participation in that part of 7th Street that Metro constructs; being that portion from the P-1 Channel to where 7th terminates now. Condition #3: No problem. Condition #4: Agree subject to Metro's Council approval; staff cannot commit Council to this dedication of property. Condition #5: Agree to and again ask for latecomer's agreement if put in by Metro. Condition #6: Must obtain Metro Council's approval to commit to. Condition #7: Agree. Condition #8: Agree. The Examiner called for further testimony in support of the application. There was none. The Examiner then called for testimony in opposition to the application. There was none. The Examiner closed the hearing, with the approval of Metro representatives, at 1:05 p.m. and noted his decision would be issued within two weeks. FINDINGS, CONCLUSIONS & DECISION: Having reviewed the record in this matter, the Examiner now makes and enters the following: FINDINGS: 1. The applicant, the Municipality of Metropolitan Seattle (METRO), filed a request for approval of a conditional use permit to allow the construction of additional sewage treatment handling facilities. 2. The application file containing the application, SEPA (State Environmental Policy Act; RCW 43.21C) documentation, the Building and Zoning Department Report, and other pertinent documents, was entered into the record as Exhibit #1. METRO: CU-007-83 Municipality of Metropolitan Seattle July 12, 1983 Page 4 3. Pursuant to the City of Renton's Environmental Ordinance and SEPA, an Environmental Impact Statement prepared under federal auspices was utilized to review the subject proposal's environmental impact. 4. Plans'for the proposal have been reviewed by all city departments affected by the impact of this development. 5. The subject property is located in the extreme westerly portion of the city near the intersection of Monster Road and Longacres Parkway. 6. The subject site is fully dedicated to the Metro Renton Sewage Treatment Plant. The site is presently developed with facilities to accommodate the sewage generated by the existing communities on the east side of Lake Washington. The existing plant is currently operating at and on some occasions over capacity. The proposed additions would double the treatment capacity of the Renton plant. 7. The proposed additions will include as major elements: new aeration tanks, secondary sedimentation tanks, chlorination facilities, solids (sludge) processing facilities, and the construction of an effluent pump station and a tunnel to convey the effluent to an outfall in Puget Sound. The final item, the tunnel, is still under consideration by the Metro Council and further studies have been commissioned. 8. Part of the subject site was annexed into the city in April of 1959 by Ordinance 1745 and amending Ordinance 1764. Other portions of the site were annexed by Ordinance 1928 in December of 1961. The site, zoned G-1 at the time of annexation, is still zoned G-1. 9. The water system for fire flow requires modification, but the nature of the facility, a sewage treatment plant, requires specialized water systems to prevent backflow and possible contamination of public water supplies. Metro proposes working with the city departments to assure adequate fire protection for the subject site. 10. The Fire Department is especially concerned with the on-site storage of a chlorine tank car. Depending on the size of the car and Metro's needs, tank cars will be delivered to the site in the range of 1 to 2 cars monthly. The tank cars could range in size from 30 to 55 to 90 ton cars, depending on need and availability. Currently, Metro receives a 1-ton cylinder weekly. The chlorine tank car will be separated from the string of freight cars and will be placed entirely within a contained building. Facilities and equipment for containing and handling spills and other potential emergencies will be available at the site and an agreement to work with the Renton Fire Department has been assured. 11. The applicant has already applied for permission to grade and fill the subject site. The material will be generated both on-site and off-site from the proposed P-1 Channel. The storm drainage potential of the site will be maintained and the proposed structures will be above the level of expected flood waters in the event of a flood situation. 12. Development of the site will not generate much additional traffic during peak hours as the plant will be largely automated. Heavy vehicle traffic will be generated during construction with the importation of building and fabrication materials including steel and concrete. 13. The site will also generate traffic which will be involved in moving solids and sludge, from the site to remote locations. This operation will generate approximately 8 to 10 vehicle trips per day. METRO: CU-007-83 Municipality of Metropolitan Seattle July 12, 1983 Page 5 14. The applicant has agreed to construct and participate in the construction of a substantial number of roadway improvements in the vicinity of the subject site. The applicant will provide a culvert type of bridge across the P-1 Channel as an extension of S.' W. 7th Street from the Washington Technical Park. This roadway would provide an alternative route to the site and would provide an expedient route for emergency vehicles from.downtown Renton. The Public Works Department will have ultimate approval of the structural components and the design aspects of the bridge. Any traffic signalization necessary will be pro-rated among the potential users in the area. Metro, upon approval of the Metro Council, would be willing to participate in an LID for the improvement of S. W. 7th Street from its current terminus to approximately 400 feet beyond its intersection with Monster Road. Staff recommended that such approval be a condition precedent to finalization of the conditional use permit. Metro will dedicate one-half of the right-of-way for the Valley Parkway along the northern reaches of its property, generally bounded by the P-1 Channel on the east and Monster Road on the west. 15. Metro has acquired additional property which would permit the realignment of Monster Road and its intersection with Longacres Drive. Further arrangements with an additional property owner will be necessary to accomplish this realignment. Metro will provide approximately 50% of the width of the right-of-way. 16. Odors emanating from the site should be largely contained by stack scrubbers which will be installed above the raw sewage receiving station. Hoods also placed over the sludge dewatering complex will direct air to the scrubbers for odor elimination. 17. The site currently is the primary treatment plant for sewage generated by the communities on the east side of Lake Washington. Included, not only the host city Renton, but also Bellevue, Kirkland, Kent, Auburn, Redmond and Tukwila, as well as the unincorporated but serviced areas of King County. Since the treatment plant has been operating above its design capacity, many of these jurisdictions faced decisions concerning the rate of growth in their respective communities. The Comprehensive Plan for the City of Renton forecasted an increase in population, but this could only occur if a method of handling sanitary waste water was available. Similar planning in other communities was also similarly affected. The expansion of the Renton Sewage Treatment Plant will enable further development of the eastside towns commensurate with the available land areas and steady demand. 18. The area in which the subject site is located is designated as suitable for the development of public and quasi-public uses in the city's Comprehensive Plan. 19. The area is generally developed with industrial uses although development of the area is just beginning. The Longacres Race Track is located south of the subject site. Across Springbrook Creek is an area now being developed with manufacturing park type uses, including light industrial, warehousing and office uses. The area has been in transition from rural and generally open space uses to commercial and manufacturing uses and the remaining single family home in the immediate vicinity is expected to yield to the transition to more intense uses rather than signify the residential character of the area. 20. The traffic generated by the proposal as outlined in earlier findings will be predominately of a non-peaking hour character, consisting largely of the initial construction vehicles; the daily crew, which is limited by the generally automated nature of the facility, and the sludge bearing trucks leaving the site. The rail delivery of the chlorine tank car presents the greatest concern to the emergency services as the potential for harm is present from accidents both on-site and in transport through the city. Staff has recommended that Metro prepare a risk analysis and evacuation plan for the area. METRO: CU-007-83 Municipality of Metropolitan Seattle July 12, 1983 Page 6 Chlorine gas, since it is heavier than air, would tend to settle and hug the ground. The fact that the subject site and vicinity is already low lying in relationship to the majority of the residential areas should minimize the risk somewhat although the working population and race track patronage could be at risk. The nearby, location of the P-1 Channel topographically lower even yet could also channel any escaping gas to safer areas. Included as part of any emergency plan is the connection of the site via the proposed S. W. 7th Street Bridge and roadway extension. This should be required to be available prior to the storage of tank car quantities of chlorine on the subject site. 21. The applicant has proposed a major landscaping effort on the subject site. Both the applicant and city staff have emphasized the landscaping, shading and buffering along the P-1 Channel for both aesthetic and environmental reasons. Shade trees will keep the water temperature lower to enhance the fish populations which now migrate throughout Springbrook Creek. Landscaping will also be utilized to harmonize the site with other proposed landscaped manufacturing parks in the area. CONCLUSIONS: 1. The approval of a conditional use permit to allow the expansion of the Renton Sewage Treatment Plant appears to serve the public use and interest. The current plant which serves the growing urban centers on the east side of Lake Washington is presently operating beyond its design capacity. Expansion will enable the plant to adequately process sewage now generated by these communities, as well as the additional sewage these communities will generate in the face of anticipated growth. 2. The Comprehensive Plans of not only the host city, Renton, but of all the other eastside cities project increases in population and employment which would not be possible unless the plant were permitted to expand to serve these uses. The proposed doubling will meet these needs and at the same time eliminate the overflow problems which now periodically occur. 3. The expanded plant will process greater amounts of sewage and will need not only more tanks, chlorine and pumps, but larger systems to handle some of the sewage. The dewatering operation will generate additional truck trips, and the effluent increase will demand more chlorination and an entirely new method of disposing of the effluent. The precise nature of the effluent disposal system is still under review, but the probable method will not include further discharges into the Green/Duwamish River system. 4. The increased handling capacity will increase to some extent the demand on city services, including roads, water and potential demands on the city's emergency services. As a consequence of these increased demands, Metro will provide some measure of improvements to the roads and arterials surrounding the subject site. These roadway improvements will permit better access to the site for Metro's own purposes, sludge removal, equipment delivery, etc., and will improve access to the site by city emergency equipment should the need arise. These improvements will also facilitate the movement of all vehicles around the site. The current configuration of roads surrounding the site is generally circuitous and a result of happenstance. The realignments and extensions proposed will directly benefit the general public and, as a result of these improvements, the additional loads placed on the system by Metro should not adversely affect traffic . 5. The area no longer serves as a residential area and the proposed use is entirely in conformity with the Comprehensive Plan for the area in which the subject site is located. It also complies with the more far reaching intent of the Renton's Comprehensive Plan to accommodate larger poulations and an enhanced employment base. Further, it can safely be stated that the expansion is generally in compliance with most of the eastside communities' Comprehensive Plans which project greater growth in population in the already established urban centers. METRO: CU-007-83 Municipality of Metropolitan Seattle July 12, 19'83 Page 7 6. The enlargement of the plant will also carry with it an improvement of technologies to handle the solids and effluent, as well as some of the other by-products which includes odiferous compounds. The new facilities should further minimize odors generated by the operation both at the receiving end of the operation and during some of the intermediate stages by scrubbing the air before releasing it into the atmosphere. 7. The area, as indicated, has been long in transition from rural residential to industrial and manufacturing park uses, and the plant has generally been an inobtrusive neighbor to those uses. The new odor handling equipment should help further the plant's acceptability as an industrial neighbor. 8. Landscaping, as approved by the city, should also enhance the outward appearance of the plant and blend it into its environs, including the P-1 Channel and the landscaped manufacturing parks which are developing in the area. Landscaping shall provide a dense buffer along the facility's property lines, especially where those lines coincide with other than public streets. Landscaping, as appropriate to shade and moderate the temperatures of the P-1 Channel, shall be installed. All landscaping shall be subject to review and approval by the city's landscape architect. 9. The applicant will comply with the general building regulations of the city and will, therefore, provide adequate parking for supervisory personnel. Beyond the ordinary codes and regulations is the Fire Department's concern regarding the storage of chlorine on the subject site. Staff has indicated that Metro should provide a risk analysis of the plant and a specific evacuation plan. Any such plans should be formulated with the cooperation of the city's emergency response teams, including the Police and Fire Departments. 10. The applicant, as outlined in the findings above, will participate in certain roadway improvements, will provide land for other needed roadway modifications, and will participate, subject to approval by the Metro Council, in an LID for roads adjacent to the subject site. Staff has indicated that the LID approval of the Metro Council be made a condition precedent to issuance of the conditional use permit. Other roadway improvements have apparently been agreed to by the city and Metro staff in a fashion which avoids the need for subsequent Metro Council review. 11. In conclusion, the proposal appears to comply with the various criteria enumerated in Section 4-748 in that the proposed use is in the public interest, is generally compatible with surrounding uses, will use appropriate technology to minimize odors, will comply with the city's codes and ordinances, will be heavily landscaped and will provide construction, land and willingness to participate in roadway improvements which are necessary in this general area. DECISION: The conditional use permit is approved, subject to the following conditions: 1. The applicant provide affirmation that the Metro Council will permit Metro to participate in an LID which may be created to construct, improve or build the Valley Parkway Oaksdale Road). 2. Metro shall be responsible for the construction of a bridge and roadway over the P-1 Channel in the general vicinity of S. W. 7th Street. Such construction shall be completed prior to the receipt of the first chlorine tank car on the subject site. The road shall include all necessary improvements as determined by the Public Works Department, including signalization for which the applicant will be responsible for a reasonable pro rata share. 3. Metro shall improve the alignment of Monster Road along the western boundary of the subject site, including the intersection of Monster Road and Longacres Drive. METRO: CU-007-83 Municipality of Metropolitan Seattle July 12, 1983 Page 8 4. The applicant shall dedicate one-half (1/2) of the right-of-way for the Valley Parkway between the P-1 Channel and Monster Road. 5. Metro may seek latecomers agreements as determined by the City Council for any aspect of roadway improvements. 6. The applicant will prepare a risk analysis of the chlorine tank car operation and will coordinate with the Police and Fire Departments to provide for an evacuation plan for the area in the event of any chlorine leak. 7. The fire flow system provided by the applicant shall be subject to the approval of the Fire Department. 8. Landscaping as approved by the City of Renton Landscape Architect.

This means that parties to a land use decision may not communicate in private with any decision-maker concerning the proposal. Decision-makers in the land use process include both the Hearing Examiner and members of the City Council. All communications concerning the the proposal must be made in public. This permits all interested parties to know the contents of the communication and would allow them to openly rebut the evidence. Any violation of this doctrine would result in the invalidation of the request by the Court. The Doctrine applies not only to the initial public hearing but to all Requests for Reconsideration as well as Appeals to the City Council. METRO: CU-007-83 Municipality of Metropolitan Seattle July 12, 1983 Page 9 Pursuant to Title IV, Section 3015 of the City's Code, request for reconsideration must be filed in writing on or before July 26, 1983. Any aggrieved person feeling that the decision of the Examiner is based on erroneous procedure, errors of law or fact, error in Judgment, or the discovery of new evidence which could not be reasonably available at the prior hearing may make a written request for review by the Examiner within fourteen (14) days from the date of the Examiner's decision. This request shall set forth the specific errors relied upon by such appellant, and the Examiner may, after review of the record, take further action as he deems proper. An appeal to the City Council is governed by Title IV, Section 3016, which requires that such appeal be filed with the City Clerk, accompanying a filing fee of $75.00 and meeting other specified requirements.

DEPARTMENT ANALYSIS; 1. The subject site area is designated on the Comprehensive Plan as Public/Quasi-Public. The proposed expansion of the Metro sewage treatment plant facility is in general compliance with the Comprehensive Plan. 2. The proposal is being heard as a conditional use permit as the result of the underlying G-1, General Use Zoning, of the subject site. The Land Use Examiner must apply the eleven criteria delineated under Section 4-748 to consider acceptability of the proposal. 3. The proposed expansion by Metro (Municipality of Metropolitan Seattle) of the Renton Sewage Treatment Plant is the largest single public development project ever proposed within the City of Renton. The expansion would functionally double the size of the treatment plant and provide for specialized solids processing. The Metro Council adopted the basic program in 1981 to consist of three major elements: (1) construction of new aeriation tanks, secondary sedimentation tanks, and chlorination facilities for a liquid stream capacity of 72,000,000 gallons daily, (2) construction of solids processing facilities for on-site concentration, stabilization, and de-watering of wastewater sludges from the 72,000,000 gallon daily liquid stream facility, and (3) construction of effluent pumping station, tunnel, and outfall for transfer and disposal of treatment effluent in Puget Sound. The majority of the third condition requiring the pumping and tunnel for the disposal of treated effluent in Puget Sound will not be within the city limits of the City of Renton. The initial pumping station and beginning of the tunnel will be, and is, included as part of this application. 4. The Environmental Review of the proposed project was originally conducted under NEPA (National Environmental Policy Act) and is not subject to specific review under SEPA. The Environmental Review Committee considered the proposal, even though it was not within their purview to do so, and recommended that Metro modify their application to address specific problems both on-site and off-site. Metro subsequently modified their application on June 6, 1983 to address those concerns. 5. The subsequent application is of such unusual size and scope, with a total estimated cost of approximately $110,000,000, that the following specific breakdown of proposed improvements is presented for clarification: Liquid Stream: Major liquid stream improvements at the Renton plant include: a. Construction of new aeration tank. b. Construction of eight (8) new secondary sedimentation tanks and appurtenant pumping systems and distribution channels. c. Retrofit of existing secondary sedimentation tanks with new hydraulic controls. PRELIMINARY REPORT TO THE HEARING EXAMINER MUNICIPALITY OF METROPOLITAN SEATTLE: CU-007-83 JUNE 28, 1983 PAGE 4 d. Continued use of chlorine for effluent disinfection and construction of a chlorine building for receiving and storing bulk chlorine in rail tank cars. The subject of chlorine safety was discussed with the City of Renton Fire Chief and Fire Marshall during the predesign study. The. new chlorine building will have access control and entry detection devices on all doors and windows, as well as safety systems to contain and dispose of any chlorine leaks inside the building. e. Construction of a second chlorine contact channel. f. Construction of a septage dilution tank to reduce the strength of septage discharged to the influent and to control odors. Solids Stream: Solids processing facilities will include the following major improvements: a. Construction of a raw sludge blending/distribution tank. b. Construction of four (4) dissolved air flotation thickeners for thickening of combined primary and waste activated sludge. c. Construction of a thickened sludge blending tank. d. Construction of four (4) anaerobic digesters for stabilization of thickened sludge. e. Construction of a blending digester for storage of digested sludge prior to dewatering. f. Construction of a sludge dewatering building for belt filter presses and chemical storage (polymer). g. Construction of covered loading facilities for removal of dewatered sludge from the plant site by semi-trailer trucks. h. Construction of a storage tank for belt filter press filtrate. Other Improvements: Other improvements to be done as part of the on-site expansion include the following: a. Construction of a new electrical substation. b. Installation of a new computerized process control system. c. Construction of tunnels and roads for access to and maintenance of pipelines, process equipment and tanks. d. Construction of outside piping systems such as storm drains, tank drains, and air, water and chemical piping systems. e. Minor structures and process improvements such as a new prechlorination manhole, an influent flow measuring station, replacement of existing pumps with more efficient models and modifications to the grit and screenings systems. 6. The subject site is located within the flood plain of Springbrook Creek. The on-site.improvements include revisions to the dike and filling approximatey 27,500 cubic yards within the existing flood plain. In accordance with the City of Renton Environmental Review Committee's requirement to provide for compensative flood storage, Metro has started excavating the P-1 Channel. They have agreed to place a total of 99,000 cubic yards of material upon the treatment plant site out of the flood plain from the P-1 Channel. The first phase of construction of the P-1 Channel includes the excavation of 50,000 cubic yards of material. The Building and Zoning Department has issued an annual license to Metro under the special permit requirements of King County Department of Public Works, File No. SP-060-81. This will provide more than twice the flood storage capacity that is required for their proposed fill operation under this development. In addition, they have agreed to take another 49,000 cubic yards from the Four Bay area as the P-1 Channel is ex cam.utt .. PRELIMINARY REPORT TO THE HEARING EXAMINER MUNICIPALITY OF METROPOLITAN SEATTLE: CU-007-83 JUNE 28, 1983 PAGE 5 7. The proposed expansion doubles the size of the Renton Treatment Plan. Based on these substantial modifications the access for both servicing and emergency needs were modified. The Washington Technical Industrial Center, located east of the proposed P-1 Channel location, included the extension of SW 7th to the P-1 Channel. METRO has proposed at the request of both the Public Works Department and the Fire Department, the construction of a culvert type bridge across the P-1 Channel to the northeast corner of METRO's present site. This provides a new primary operational access to the site and will be utilized for sludge truck hauling in the future. In addition, it provides a faster emergency access from the downtown fire station. METRO may ask City Council for a late corner's agreement for the improvement of SW 7th Street. Discussion on the proportional share of the actual signalization of the intersection of the Valley Parkway and SW 7th can be evaluated at a future time. Public Works Department reserves all approval on all plans for the bridge, street improvements, and intersection improvements for this extension of SW 7th Street. 8. METRO has also revised their application to include the dedication of one-half of the right-of-way for the Valley Parkway and improvements along the northern propoerty line of the subject site. This is on the alignment for the extension of the Valley Parkway west of the P-1 Channel to interconnect with Monster Road. METRO has also stated that it has no objection in participating in an LID to extend SW 7th Street to the intersection of the future Valley Parkway and then northerly and westerly over the P-1 Channel to 400 feet beyond the intersection with Monster Road. METRO points out that its staff cannot make a commitment to an LID and the commitment must come directly from the METRO Council after it has an opportunity to review the petition. It would appear that in this case the City would be delinquent in not requiring the filing of restrictive covenants as a condition of the conditional use permit to participate in that LID. The alternative to METRO is to construct that one-half of the right-of-way, basically two lanes out of a proposed four lane major arterial, and obtain late corner's fees from subsequent developments utilizing that stretch of the Valley Parkway through late corner's agreements. 9. METRO recently acquired an adjacent parcel of property owned by Burlington Northern. They have agreed to realign Monster Road to intersect with Longacres Drive through this newly acquired parcel of property. METRO will provide approximately 50% of the 60 foot of right-of-way and extend Monster Road to that intersection. They do require access to this roadway for both emergency and administrative vehicles. Some minor intersection improvements are to be included in the improvement of Monster Road. This commitment is contingent upon developing a reasonable and equitable right-of-way plan with the neighboring property owner and the results of more detailed design in coordination with the City. Specific design plans will have to be approved by the Public Works Department on the exact realignment of Monster Road. 10. METRO has requested a waiver of improvements on Monster Road along the westerly side of the property and on the segment that would be realigned. The Board of Public Works is considering granting this modification based upon the fact that the major arterial will be the Valley Parkway in this general area and that as little traffic as possible should be directed to this segment of Monster Road. The applicant has agreed to make improvements to include a 24-inch wide, 2-inch Class B asphalt roadway with improved drainage. The Board of Public Works is considering this request based upon METRO's cooperation in dedicating and constructing major portions of the Valley Parkway. PRELIMINARY REPORT TO THE HEARING EXAMINER MUNICIPALITY OF METROPOLITAN SEATTLE: CU-007-83 JUNE 28, 1983 PAGE 6 12. METRO has also agreed in their letter of June 6th, to upgrade the fire protection facilities to the City of Renton's code requirements. Specific design plans have been submitted to the Public Works Department and the Fire Department for review. METRO has expressed a concerned over guaranteeing the safety of the water quality in the City mains. The problem results because of possible backdrafts of contaminated water from the sewage into the City's water main system. The present system has an airgap in between the water tower and the main thus creating an appropriate sanitary separation. The problem is enough water flow to recharge the existing reservoir to meet fire flow requirements for the entire site. METRO contends that it should not upgrade the City's area water system but should provide a separate system adequate to meet the fire flow needs of the new facilities. Both sides in the issue wish to reserve the right to negotiate farther on the problem. However, it should be noted that METRO has agreed to meet the City's fire code requirements. The second issue that the Fire Department is concerned with has been the chlorination building. METRO will have a large supply of chlorine stored in a railroad tank car. The building itself meets all hazardous standards requirement for leakages or potential accidents. The new access proposed off of SW 7th Street along with the existing access, provides reassurance in the mind of the Fire Department in reaching the site faster to contain any hazardous situation within the chlorine building. The City should recognize a potential hazard and be concerned with potential plans for evacuation of the general area. It would appear advisable for the City to require METRO to provide a risk analysis of the shipment and operation as it relates to the City's disaster plan. A specific evacuation plan should be recommended to the City in case of a spill. 13. The Land Use Hearing Examiner must consider the following eleven criteria in reviewing a conditional use permit request: Comprehensive Plan: The proposed use shall be compatible with the general purpose, goals, objectives and standards of the Comprehensive Plan, the Zoning Ordinance and any other plan, program, map or ordinance of the City of Renton. The METRO proposed expansion is compatible with the general purpose, goals and objectives and standards of the Comprehensive Plan. The subject site was designated for this specific public use in the original Comprehensive Plan which was adopted in 1965. The plant expansion is critical to the enactment of the Comprehensive Plan for the entire City, for without the necessary sewer utilities the goals of density and community development cannot be achieved. Community Need: There shall be a community need for the proposed use at the proposed location. Presently there is a dramatic community need for the proposed expansion of the sewage treatment plant. Present volumes exceed design operational capacity of the present plant. Without the expansion, basic development in the cities of Kirkland, Bellevue, Renton, Auburn and Kent would be completely stopped. In general, it could be said that the plant will create major impacts because of an over concentration of its particular use. However, because of the design of sewers, this is the most logical location for a treatment plant within the entire sewage drainage basin. Renton has accepted the responsibility of this type of land use within its city limites to provide services to the adjoining communities. Effect on Adjacent Properties: The proposed use at the proposed location shall not result in substantial or undue adverse effects on adjacent property. The expansion of the METRO sewage treatment plant will increase the effectiveness and effeciency of the existing operation. Presently, it may be considered to create some adverse affects on adjacent properties in the form of odors and unsightliness. The proposal will increase the handling capacity and the degree of treatment along with providing major landscaping buffers and updated landscaping program for the entire complex. PRELIMINARY REPORT TO THE HEARING EXAMINER MUNICIPALITY OF METROPOLITAN SEATTLE: CU-007-83 JUNE 28, 1983 PAGE 7 The proposal complies with the requirements of lot coverage, yards and building heights for the G-1 zone. The future power substation though, will have equipment which exceed the 35 foot height limit. Utilities have not be specifically limited in height because of their typical overhead nature and size of equipment involved. Compatibility: The proposed use shall be compatible with the residential scale and character of the neighborhood. There are no adjacent residential neighborhoods in the immediate area. The Comprehensive Plan has designated the entire vicinity as Manufacturing Park or Public Use. There is one adjacent single family residence but it is believed it is transitional in nature and not an established trend. Therefore, the criteria does not comply. Parking: Parking areas shall not be allowed in the front, side and rear yard setbacks except upon approval by the Hearing Examiner as provided in Section 4-708(B)(3)(a). Parking under the building structure should be encouraged. Lot coverage may be increased to as much as seventy-five percent (75%) of the lot coverage requirement of the zone in which the proposed use is located if all parking is provided underground or within the structure. This parking requirement does not really apply to the new expansion. Parking has already been provided per code requirements for the administration building and the worker's on-site. Most of the facility will be automated with primary employment directed towards maintenance. Traffic: Traffic and circulation patterns of vehicles and pedestrians relating to the proposed use and surrounding area shall be reviewed for potential effects on, and to ensure safe movement in the surrounding area. Construction of the site will create the majority of traffic. Large amounts of steel, concrete and finished machinery will be imported into the site. The anticipated filling and grading of approximately 250,000 cubic yards will be conducted almost exclusively on the site and the adjacent P-1 Channel. Minor truck traffic is anticipated with equipment possibly coming to and from the site. The project is of large enough scale that most equipment will probably be stored on the site for the duration of the contract period. Operational traffic is seen primarily in the independent septic pumpers coming in and disposing of the sewage. This presently averages less than 15 vehicle trips per day. Exporting of the sludge from the site would be in major semi trucks and would propably not be greater than 5 trips per week. The function of the redesign is primarily to dewater the material and pump the waste water to Puger Sound through a tunnel. Noise, Glare: Potential noise, light and glare impacts shall be evaluated based on the location of the proposed use on the lot and the location of on-site parking areas, outdoor recreational areas and refuse storage areas. Basic noise and glare will be kept at a minimum from the adjacent landscaping. In the past, the primary problem with the facility has been the generation of odors as a result of overcapacity operation.. This should be minimized or possibly totally eliminated with the redesign of the facility. Landscaping: Landscaping shall be provided in all areas not occupied"by buildings or paving. The Hearing Examiner may require additional landscaping to buffer adjacent properties from potentially adverse effects of the proposed use. PRELIMINARY REPORT TO THE HEARING EXAMINER MUNICIPALITY OF METROPOLITAN SEATTLE: CU-007-83 JUNE 28, 1983 PAGE 8 A schematic landscaping proposal has been presented along with the conditional use permit application. It generally provides major buffering along the perimeters of the site adjacent to the proposed P-1 Channel. Total landscaping becomes critical when considering such a large site of 82.6 acres. Specific evaluation should be conducted by the City's Landscape Architect at the time of building permit approval. The primary intent is to blend the large site and make the perimeter landscaping aesthetically pleasing along with enhancing the wild life mitigation proposed in the P-i Channel. Accessory Uses: Accessory uses to conditional uses such as day schools, auditoriums used for social and sport activities, health centers, convents, preschool facilities, convalescent homes and others of a similar nature shall be considered to be separate uses and shall be subject to the provisions of the use district in which they are located. This criteria does not apply in this case. The entire facility is dedicated to a sewage treatement plant facility. Conversion: No existing building or structure shall be converted to a conditional use unless such building or structure complies, or is brought into compliance, with the provisions of this Chapter. This provision does not apply because the facility has continuously been a sewage treatment and no conversion is sought. Public Improvements: The proposed use and location shall be adequately served by and not impose an undue burden on any public improvements, facilities, utilities and services. Approval of a conditional use permit may be conditioned upon the provision and/or guarantee by the applicant of necessary public improvements, facilities, utilities and/or services. The proposed expansion does not create any undue burden on any public improvement facilities or utilities in the area. This is only true as a result of METRO modifying their application with their letter dated June 6, 1983. This provides for necessary dedications, street improvements, and participation for other public improvements in the general area. The only issue that may remain is the issue of water main extension through the subject site for the general integrity of the City's fire fighting system in this area. The staff's position is that this issue is a technical issue which must be resolved between the Fire Department and METRO. METRO has stated that they will meet the City's fire code requirements, but this does not include a new loop system to upgrade the City's area water system. The philosophical difference is that METRO believes that it must protect its own facility to required code but it should not, because of its unique location and problems associated with water and sewage contamination, provide an intertie to generally upgrade the area's watermain system. 14. Various department comments are attached for the public's and the Examiner's review. These comments have been extensively discussed in both the agreement of METRO to revise their application, dated June 6, 1983. 15. The proposal as presented by METRO is a logical extension of a necessary service to allow continued development of the general region. In the past, the Land Use Hearing Examiner has expressed concern that the sewage facilities was not adequate to allow continued growth without drastic controls. This proposal by METRO basically doubles the size of the plant to allow for that continued growth according to the adopted Comprehensive Plans and zoning of the respective jurisdictions involved in METRO. PRELIMINARY REPORT TO THE HEARING EXAMINER MUNICIPALITY OF METROPOLITAN SEATTLE: CU-007-83 JUNE 28, 1983 PAGE 9 M. DEPARTMENTAL RECOMMENDATION: Based upon the above analysis, it is recommended that the conditional use request, CU-007-83, be approved subject to the following conditions: 1. Approval of an approriate fire protection system meeting the City of, Renton's code requirements by the Fire Department. 2.Construction of SW 7th Street from its existing completion point at Washington Technical Center to the subject site. Construction will include the intersection at the Parkway the intersection at the Parkway and S.W. 7th Street with provisions for future signalization. 3. Construction of a culvert-type bridge over the P-1 Channel to the NE corner of Metro's site to include and be approved by the Public Works Department. The Public Works Department shall be granted full authority to determine whether the excavation of the P-1 Channel to its designed section through the bridge area should be required. This item should not be appealable to either the Hearing Examiner or the City Council because the City has previously approved the necessary design configuration for the.P-1 Channel. 4. Metro shall dedicate one-half of the right-of-way for the Parkway and its improvements along the northern property line. This dedication shall be a minimum of 40 feet in width to comply with the needs of an industrial collector arterial. 5. Metro shall signalize the intersection at S.W. 7th Street and the Parkway at the time determined by the Board of Public Works. This may correspond with the development of Phase 2 or Phase 3 of Washington Technical Park. At that time, a proportionate share between the developers of Washington Technical Park and Metro shall be calculated. 6. Metro shall sign restrictive covenants or to participate in an LID extension of the Valley Parkway from S. W. 7th Street over the P-1 Channel to 400 feet beyond the intersection of Monster Road. 7. Metro will improve Monster Road along Metro's western property line along with a realignment to be approved by the Public Works Department to connect Monster Road to Longacres Drive to a standard of 24 ' wide, 2" Class B asphalt roadway, with improved drainage. This will include minor intersection improvements at the intersection of Longacres Drive and Monster Road. 8. METRO shall prepare a risk analysis of the shipment of chlorine and operation of its proposed chlorination facility as it relates to the City of Renton's disaster plan. This shall include a specific evacuation plan. 7 zSB `.,,,.? n ' y.., . I ski • .Z4 I --• y11 )i, .

RENTON,WASH.98055 9,® m• 0 94 ED SEP-TO' BARBARA Y. SHINPOCH MAYOR MEMORANDU ' Date: March 4, 1983 To: Dick Houghton Ron Nelson From: Bob Bergstrom Subject: Metro Treatment Plant Expansion The Department of Public Works Engineering Division has many" serious concerns with the Metro Renton Treatment Plant expansion project and their lack of addressing City requirements in the phased development. 1.. Internal Plant Fire Protection Metro has an internally-operated water system fed from a single 8" metered supply into their small 10,000 gallon reservoir. The fire flow capacity is unknown and fire flow testing is needed to adequately evaluate the fire sys- tem performance. 2. New P-1 Channel Bridge - S.W. 7th St.. Extension Metro's new haul route for sludge trucks, via S.W. 7th St. , will make Metro liable for latecomer's fees onthe two signalized intersections at (a) Powell and Grady Way and, (b) S.W. 7th and Hardie Ave. S.W. The bridge itself should be open for public access, separate technical plan submittals must be pro- vided, and ramped access down to the future P-1 Channel mustbe provided. The P-1 Channel should be fully excavated through the bridge area to its final design section. Provisions for future signalization of the S.W. 7th St. and Valley Parkway intersection must be provided, and costs for this signal will be shared between Metro and the neighboring Washington Technical Center development. 3. Monster Road Off-Site Improvements Monster Road must be improved to a 36' wide street - with curb and gutter both sides, storm drainage, street lights and sidewalk on one side. 4. Valley Parkway Off-Site Improvements Because of Metro's vague property acquisition plans on their north property line, this requirement's limits of work are not well defined. However, Metro will have to provide 1/2 of the right-of-way and build 1/2 of Valley Parkway along their north plant frontage. l• a p.. Metaro Treatment Plant I ion. 2 - March 4, 1983 This is a major arterial, four travel lanes, with a two-way left turn center lane, curb, gutter and sidewalk with street lighting and storm drainage. Metro's obligation is for 1/2 of the street improvements. 5. Monster Road Realignment The south end of Monster Road must be realigned to connect directly into Long- acres Drive S.W. This would--be_a 36_' wide road with curbs, gutters, one side- walk and street lighting. This new road would pass through the south edge of the Metro site. 6. Longacres Drive S.W. Off-Site Improvements The north margin of Longacres Drive S.W. , along the Metro frontage must be improved with curb, gutter, sidewalk and street lighting. 7. P-1 Channel and Interim Flood Control The flood control issues are very complex. and depend in part if the City can bring the Soil Conservation Service back into the project. Metro's present phase will fill an area outside of their present dike. Com- pensating storage should be provided in ;the P-1 Channel right-of-way presently controlled by the City of Renton. The Metro plan for a Flood Water Storage Basin on the north portion of their site is not a recommended option. Metro has deeded the necessary channel rights-of-way, but has not firmly com- mitted to accepting their share of the excavated spoils from the P=1 Channel work. Metro's share of the Phase I P-1 Channel is about 165,000 cubic yards. Previous negotiations have only brought the City some conditional acceptance from Metro to accept their share of this fill . The City- needs a firm right-of-entry agreement from Metro to move ahead with SCS participation. 8. Haul Route Must be Defined Any earth work hauling for this plant expansion must have a haul route defined. Any hauling into Renton from the Seahurst Tunnel must be defined. 9. Sanitary Sewer Service to North End of Plant Metro has no provision for sanitary sewer service connections from the north end of their plant. While Metro has major internal plant sanitary sewers, they are resisting allowing connection from the north-. Thi-s- new connection- point to service areas to the north from Washington Technical Center, Container Corp. and other developments up Monster Road are required. g64,Reielvw REB:jft VIEWING DEPARTMENT/DIVISION'_L//C(y E=4)(PPROVED IDAPP.,ED WITH CONDITIONS L] NOT APPROVED I6t'itiLL-K kireitir of gull.®/Z 6 srrrdcr,O ) 1J/LL re-c-c ace,e), GJ4r6 re.

He also stated they would contact Mr. Wells and obtain the correct document. Ron Nelson reported that the Building Department had already issued a pre-citation and that the attorney for 0/W Properties had contacted him asking about the next step. Mr. Nelson indicated he would like this matter turned over to the City Attorney for evaluation. Moved by GEISSLER, seconded by CLEMENS to refer to City Attorney. MOTION CARRIED b.

Board asked that Don Monaghan continue to handle this matter. g. Dr. E. Bennett - status of right-of-way permit and deferral . It was reported that Dr. Bennett had revised his plans, they were approved and there is no longer any need for permit and/or deferral . h.

Southwest 7th Street will be extended westerly to the point of the future Valley Parkway and Southwest 7th Street intersection' and such intersection will be provided along with provisions for future signalization. From the intersection, a culvert type bridge will be constructed over the P-1 channel to the northeast corner of Metro's site to satisfy. Metro and the City Fire Department 's preference for site access . Excavation of the P-1 channel to its design section through the bridge area should not be recommended to the hearing examiner but negotiated as part of the bridge design .

Metro has reviewed the City' s letter which out- lines conditions that the City departments may recommend to ,the Land Use Hearing Examiner concerning the subject permits. We would like to ensure that this response and past Metro correspon- dence is entered into the hearing examiner' s file for: his 'review prior to the hearing. In addition, we request a-meeting withCMr. Houghton, Mr. Nelson, Mr. Geissler and the Mayor prior to the formulation of final recommendations by the City departments 'to discuss several problems outlined below. Generally, Metro is concerned that the list of improvements .' • recommended by the City are excessive, appear to lack legal . , authority and are disproportionate to the impacts caused by the::!- plant enlargement. It is difficult to assess the legal grounds. for many of the City' s proposed conditions since no response was provided to my request for clarification on this matter. Metro understands that the City may attach reasonable conditions to the granting of a conditional use permit, and Metro is willing to " cooperate with the City, in a mutually beneficial effort to. - upgrade the vicinity streets. However, those conditions must-:ADO reasonably related to the plant enlargement' s impact on' its - surroundings and cannot be imposed arbitrarily. We estimate• th'at the improvements suggested by the City could cost Metro up to2.5 million. In reviewing the suggested street improvements, we have been unable to find a comprehensive plan for upgrading the traffic circulation problems in the vicinity of the plant. Where plansdoexist, it seems that some of your suggested improvements are inconsistent. For example, your request for Metro to provide one-half of the Valley Parkway right-of-way and improvements Dj 1 Mr. Roger Blaylock May 9 , 1983 H u LU VLL 1 Page 2 MAY 1 198 along the northern plant property line is not only inconsistent with past traffic plans but suggests a horizontal alignment which is technically undesirable. (Reference City of Renton, Valley Parkway Alignment, sheet 3 of 3 , prepared by URS Company and Brown and Caldwell; letter to the City of Renton dated April 27 , 1983, Proposed Horizontal and Vertical Alignment of Future Valley Parkway, both attached. ) Additionally, we couldn' t find any evidence that your request for realigning Monster Road was based on an existing traffic plan. The following is Metro' s response to each item in your March 16 , 1983 , letter: Internal Plant Fire Protection. Metro' s water storage tank is 50 ,000 gallons, not 10 ,000 gallons. Metro will work with the City to ensure that the fire protection system meets reasonable provisions of the city code. However, we do not believe that Metro should be required to provide a new 12" water main across its property for wter service to the general area. Although not mentioned specifically in your letter, this requirement has been suggested in more recent meetings. Estimated cost is $106 ,000 , based on the latest discussion with the City. New P-1 Channel Bridge - S.W. 7th Street Extension. Metro is reconsidering the development of the P-1 channel plant access bridge and 7th Street extension based on recent conversations with the City staff. A record of that discussion is attached for 411, your review. We would like the City to approve the concept of a bridge connection, which would be open for public access as requested, without making it a requirement. We were under the impression from past discussions with the Renton Fire Chief and from reviewing the City' s code that this improvement would be required. The Fire Chief desires a better access to the proposed chlorine storage facility than that provided by the existing plant access. We had originally proposed Longacres Drive as an access option, but City staff were opposed because of certain design/traffic safety concerns with intersecting Longacres Drive. It appears that the City has reconsidered its concerns in view of the request for Metro to realign Monster Road to intersect with Longacres Drive near the same point we had originally proposed. If implemented, the plant access bridge improvement is estimated to cost approximately $640,000 , without the latecomers fees for signalization which we have no problems with. Also, we would agree to fully excavate the P-1 channel only through the immediate bridge area but the city would be responsible for maintenance of that area which might be subject to ponding. We are now considering an access option which might be acceptable in conjunction with the realignment of Monster Road. ci orDr,c,r.,, Mr. Roger Blaylock i1eirarnt I IMay9 , 1983 uva uPage3 Monster Road Off-Site Improvements. We believe that the wideningofMonsterRoadto36feetwithcurbsandguttersonbothsides, storm drainage, street lights and sidewalks on one side is un- justified. We also question the legal authority for imposing improvements on more than one-half of the street. We believe 15 that the public benefits of this extensive work, at an estimated cost of $375 ,000 , are at best dubious. Since the future Valley Parkway will be the major arterial in the area and Monster will be a secondary collector, Metro suggests that a better solution would be to reduce the requirement to at 24 foot-wide new asphalt road with some improvement to the sight distance problems. Further, we believe that a reduction in this requirement could include a condition that Metro work with the City on realigning Monster Road, which is discussed below. Finally, we believe the City should explore with some vigor the possibility that adjoin- ing landowners assist with the Monster Road improvement. Valley Parkway Off-Site Improvements. Because of the vague alignment of the Valley Parkway and because the Valley Parkway is a general improvement in the area, we believe that Metro should not be obligated to provide one-half of the right-of-way and improvements. As previously discussed, it appears that the City' s current street plan calls for the Valley Parkway to be aligned in a location that would not require the use of Metro property. An alignment along one-half of Metro' s northern property also appears to be technically undesirable. If Metro decides to abandon the P-1 channel bridge access, the Valley Parkway would have no direct benefit to Metro, nor would Metro' s presence impact the Parkway in a significant way. The Valley Parkway has been planned for sometime, and therefore, the plant enlargement should not be construed as impacting the need for this street improvement. This suggested condition is estimated to cost $210 ,000 , without land costs included. Monster Road Realignment. We believe that the City has no valid legal grounds for recommending such a condition. It is difficult d` to identify the City' s design goal for such a suggested street improvement since no specific street plan is available. We are particularly concerned about this condition because it could result in severance to property which we are presently negoti- ating a purchase. The property has an irregular shape with power line easements, making it difficult to develop without the complication of realigning Monster Road. However, we are willing to work with the City staff on developing a realignment project, provided that the City is willing to negotiate with the neighbor- ing property owner to the south for additional right-of-way and that a traffic plan be developed to minimize impacts to Metro from Longacres traffic. We foresee this improvement as an 6211C1rig'in:r - izt )TilMr. Roger Blaylock May 9 , 1983 UCL LU`v'l J Page 4 MAY 1 1 1983 extension of the 24 foot-wide asphalt upgrade to Monster Road. We estimate the suggested improvement to cost up to $103 ,000 without land costs. Longacres Drive S.W. Offsite Improvement. Metro is in the ill, process of negotiating with Burlington Northern for the purchase of property which is described as "Metro frontage" in your ir letter. A purchase agreement could take at least six months to consummate, if at all. Even if we succeed in acquiring the property, we question the reasons for curbs, gutters and lighting along this segment of roadway. Estimated cost is $27 ,000 . P-1 Channel and Interim Flood Control. Metro has cooperated with the City for providing flood control in the P-1 Channel in con- junction with our site preparation contract rather than excava- 7 ting a storage basin as originally planned. The site preparation contract has been awarded and the cost to Metro is based on the bids received: $216 ,000 for the P-1 channel versus $86 ,000 for the storage basin for a net cost to Metro of $130 ,000. In regard to firm commitments for accepting P-1 channel spoils, evidence from past correspondence indicates that Metro made a commitment to the City for accepting 99 ,000 cubic yards of spoils from the P-1 channel. About six months ago, the City informed Metro that our share had increased to 150 ,000 cubic yards and then, more recently, to 165,000 , due to the recent purchase of property. We do not understand how Metro' s "share" can increase by 65% when the recent land purchase amounts to about a 16% increase. It seems that the definition of "share" is being construed loosely and that the methodology for distributing 165,000 cubic yards of P-1 channel spoils to Metro should be re- viewed for its equity. Metro will be disposing of approximately 50 ,000 cubic yards of spoils on its property as a result of the P-1 channel excavation work discussed above. Based on the past "commitment" , we are obligated only to accept 49 ,000 cubic yards more. We have stated to the City in recent correspondence that Metro would be willing to negotiate the acceptance of even more spoils from the P-1 channel, but that requiring the increased quantity is unaccep- table. We cannot be put in a position of giving the City an open ended" obligation for disposing of P-1 channel spoils. We will need to specifically define fill elevation constraints on our property and to have agreed-upon time constraints from the City before we can commit to accepting additional fill. Addi- tional fill requirements cannot be imposed unilaterally; to do so raises a question whether Metro and the City even have an agreement" at all. sad""',--_-_ LS(L Li Mr. Roger Blaylock May 9 , 1983 Page 5 MA Y 11 Haul Route Must be Defined. No earthwork hauling from the plant 00 is foreseen for this enlargement. Hauling of spoils from the effluent transfer system will be defined when that project progresses to a more defined level of detail. Sanitary Sewer Service to the North End of Plant. Metro is not obligated to provide local sewerage collection, particularly from the internal plant system. The internal plant system was designed to allow surcharging, which would result in sewage flooding below certain elevations off-site. Therefore no connec- tion can be allowed. There is a 12-inch stubout in the junction structure of the southside and eastside interceptors that the service area to the north could utilize if in accordance with your approved local comprehensive plan. Supplemental Environmental Analysis. The additional environ- mental information you requested is attached. If you have any questions, please let me know. We await your advice of when we can meet with Mr. Houghton, Mr. Nelson, Mr. Geissler and the Mayor.

Bergstrom: Based on progress made with the City of Renton concerning approval of the grading license , Metro is anticipating that Schedules #1 (Base Bid ) and #3 ( P-1 Channel) of the Site Preparation contract will be awarded. Since we are opening bids on April 5 , 1983 , I would like to confirm my understanding of the City 's position on the. following items based on past discussions with you and other City staff. 1 ) In order to relocate the existing flood dikes around the Renton Treatment Plant as proposed , Metro is required , by regulation , to provide compensating flood storage. Our original proposal in meeting this requirement was to excavate 27 , 000 cubic yards from our property to the north of the proposed dike . An alternative proposal desirable to. the City and Metro is to excavate the P-1 Channel which involves excavating approximately 50 ,000 cubic yards or 23 , 000 additional yards than originally anticipated. It is our understanding that the City will allow Metro credit for the equivalent cubic feet of flood storage that the additional 23, 000 cubic yards of excavation represents in the event Metro wishes to place fill on its property in the future within the FEMA designated flood area . 2 ) Metro has a past commitment to the City that it will allow approximately 100 , 000 cubic yards of spoils from the P-1 Channel project to be disposed on the Renton Treatment Plant property . If bid schedule No . 3 is awarded , approximately 50 , 000 cubic yards of P-1 Channel material will be excavated by Metro and disposed of on the Renton Plant property . Recently the City of Renton Mr . Robert Bergstrom March 29 , 1983 Page Two has requested that Metro accept an additional 65 ,000 cubic yards of spoils from the P-1 Channel . We are willing to cooperate with you on disposing of P-1 Channel spoils on the treatment plant property . However , our ability to make a commitment must be predicated on the timing of the P-1 Channel project and of Metro 's plans to enlarge the Renton Plant in the future . Metro cannot commit to accepting the additional 65, 000 cubic yards at this time without a firm schedule for construction of the P-1 Channel and without full knowledge of future construction impacts on the site . Therefore , it is my understanding , based on our previous discussions , . that the City will be flexible on this issue . 3) Metro has recently proposed to the City that an existing Washington Natural Gas (WNG) gas main within Metro' s property be relocated into the proposed P-1 Channel maintenance road . WNG has tentatively approved the, proposed location which would require an easement . The easement would be in the maintenance road from a position near the southeast to a position near the northeast corner of Metro ' s property . You stated that the City has title to the property and can execute such an easement within the subject property. You also indicated that the City , in general , has no problem with the proposed alignment . I will contact you in the near future to arrange a meeting between the City and WNG to discuss the technical and right-of-way aspect in more detail . Thank you for your cooperation . Unless we hear from you by April 4 , 1983 , I will assume that the preceding statements reflect the City ' s position. Very truly yours , W9AmAtcya avid G. Hammond Project Manager , DGH : jc cc .

These activities are within the scope. of the original special permit issued to King County Public Works Department concerning the excavation and storage of fill materials surrounding the Phase 1, East Side Watershed Project. The City has just issued a Shoreline substantial development permit for the same work to construct the P-1 Channel and detention pond (copy enclosed) which would allow Metro to conduct their filling and grading activities according to their time schedule. The Shoreline's permit was mailed to the State of Washington on Tuesday, March 15. We expect receipt and approval by the end of April, 1983. This would allow a May 1 startup date for your excavation and filling operations. Under the City of Renton's Mining and Grading Ordinance, the Building and Zoning Department processes an annual license to assure that the contractor is complying with the intent of a special permit. Forms have already been sent to you for completion and resubmittal. It is anticipated that this license can be issued immediately upon approval by the Department of Ecology of the substantial development permit. This application should be presented to our department as soon as possible to allow adequate processing prior to issuance.

Hammond Project Manager Municipality of Metropolitan Seattle Exchange Building 821 Second Avenue Seattle, WA 98104 Re: Expansion of Existing Wastewater Treatment Plant/Metro Special Permit SP-006-83 and Conditional Use Permit CU-007-83 Dear Mr. Hammond: The City of Renton offers the following preliminary suggestion of conditions that the various City departments will recommend to the Land Use Hearing Examiner concerning the conditional use and special permit applications. These conditions have been reviewed and accepted by the Environmental Review Committee without a statement of lead agency status or as items of environmental mitigation. The City's present position is that if the applicant is willing to modify their conditional use project to include these items, then the City will not undertake the dispute over lead agency status. Internal Plant Fire Protection: Metro has an internally-operated water system feed from a single 8" meter supply into its small 10,000 gallon reservoir. The fire flow capacity is unknown and fire flow testing is needed to adequately evaluate the fire system performance. It is the City's intent that if the system needs to be upgraded, then Metro shall provide that as part of their total improvement proposaL New P-1 Channel Bridge - S.W. 7th Street Extension. Metro's new haul route for sludge trucks, via S.W. 7th Street, will make Metro liable for latecomers fees on two of the signalized intersections at (a) Powell Avenue S.W. and S.W. Grady Way and, (b) S.W. 7th and Hardy Avenue S.W.. The extension of S.W. 7th Street via the bridge will be a cost borne solely by Metro for its access to the northeast corner of the subject site. The bridge itself should be open for public access, separate technical plan submittals must be provided, and ramped access down to the future P-1 Channel must be provided. The P-1 Channel should be fully excavated through the bridge area to its final design section. Mr. David G. Hammond March 16, 1983 Page 2 Provisions for future signalization of the S.W. 7th Street and Valley Parkway intersection must be provided, and cost for this signal will be shared between Metro and the neighboring Washington Technical Center development. Monster Road Offsite Improvements: Monster Road must be improved to a 36' wide street - with curb and gutter on both sides, storm drainage, street lights and sidewalk on one side. The issue of whether these major improvements on Monster Road should be shifted to the Valley Parkway is an issue which can only be resolved by the Board of Public Works in considering a deferral or waiver of the required improvements to Monster Road. Prior to the Board of Public Works making a decision, Metro and the Department of Public Works should make a formal agreement as to the specific improvements. Valley Parkway Offsite Improvements: Because of Metro's vague property acquisition plans on their north property line, this requirement's limits of work are not well defined. However, Metro will have to provide one-half of the right-of-way and build one-half of the. Valley Parkway along their northern plant frontage. This is a major arterial, four travel lanes, with a two-way left turn center lane, curb, gutter, and sidewalk with street lighting and storm drainage. Metro's obligation is for one-half of the street improvements. Monster Road - Realignment: The south end of Monster Road must be realigned to connect directly into Longacres Drive S.W. This would be a 36' wide road with curbs, gutters, one sidewalk and street lighting. This new road would pass through the south edge of the Metro site. Longacres Drive S.W. Offsite Improvements: The north margin of Longacres Drive S.W., along the Metro frontage, must be improved with curb, gutter, sidewalk and street lighting. P-1 Channel and Interim Flood Control: The Flood control issues are very complex and depend in part if the City can bring the Soil Conservation Service back into the project. Metro's present phase will fill an area outside of their present dock. Compensating storage should be provided in the P-1 Channel right-of-way presently controlled by the City of Renton. The Metro plan for flood water storage basin on the northern portion of their site is not a recommended option. Metro has deeded the necessary channel right-of-way, but not firmly committed to accepting their share of the excavated spoils from the P-1 work. Metro's share of the Phase 1 P-1 Channel is about 165,000 cubic yards. Previous negotiations have only brought the City some conditional acceptance for Metro to accept their share of this fill. Mr. David G. Hammond March 16, 1983 Page 3 The compensating storage site which was originally planned along the northern property line could accommodate much of the necessary 165,000 cubic yards of dredge debris. The City needs a firm right of entry committment from Metro to move ahead with SCS participation. Haul Route Must be Defined: Any earthwork hauling from the plant expansion must have a haul route defined. Any hauling into Renton from the Sea-First Tunnel must be defined. Sanitary Sewer Service to North End of Plant: Metro has no provisions for sanitary sewer service connections from the north end of their plant. While Metro has major internal plant sanitary sewers, they are resisting allowing connection from the north. This new connection point to the service areas to the north from Washington Technical Center, Container Corporation and other developments up Monster Road are required. Supplemental Environmental Analysis: Additional detailed analysis of truck traffic from the sludge disposal and odors and visual impacts from solids handling need to be addressed prior to the public hearing. Specifically the issues of volume of traffic, route, size of vehicles, and potential for hazardous waste from industrial users should be evaluated. The above suggestions relate a specific review point of the City of Renton staff concerning the expansion of the Metro Treatment Plant. Several of the items appear to be very minor in scope and probably within the design parameters of your existing proposal. On the other hand, some of the issues need specific negotiation between the City and Metro either at the time of the conditional use permit or as a modification to the application. These conditions represent a minimum necessary modification to the proposal as seen by the City of Renton to be acceptable and compatible with community policies and directives.

Richard Houghton Director of Public Works MAR 5 1983CityofRenton 200 Mill Avenue South Renton, Washington 98055 Renton Treatment Plant Enlargement Dear Mr. Houghton : This letter is in regard to our meeting of February 24, 1983 concerning the Renton Treatment Plant enlargement . During that meeting we discussed many aspects of the project including requirements and desires of the City of Renton for other improvements in conjunction with the treatment plant enlargement. I would like to address these points and provide some clarifi- cation by topic . 1 . Flood Control : Metro will be required to excavate approxi- mately 27 , 000 cubic yards of material on its own property adjacent to the P-1 channel at a cost of approximately 102, 000 in order to provide compensatory flood storage for relocating the existing dikes . Alternatively, it is the City 's desire and Metro agrees that excavating approximately 60 , 000 cubic yards of material from the P-1 channel under the City's direction for an approximate cost of $220, 000 would be more beneficial . We will need written assurance that ; ( 1 ) the provision of this flood storage will allow Metro to raise the contours of all its land for its own future development within the existing and proposed property boundaries without any further flood storage requirements ; and ( 2) the requirement to accept over 40 , 000 cubic yards of additional spoils from the P-1 channel would be negotiable . We would also like the City 's approval to relocate the WNG ' s gas pipeline from the eastern boundary of Metro ' s property into the P-1 channel maintenance road . The easement would need to be within the maintenance road and extend from a position near the southeast corner to a position near the northeast corner of Metro 's property . We believe the mutual benefits which accrue to the City , Metro and adjacent property owners off-sets some of the additional expense to be borne by Metro. We also believe that a portion of these additional costs should be considered as credit against any City requirements for other improvements. trf•-. 1++;, tea:.;.r t t- e• .`?:• t-.. Mr . Richard Houghton March 8, 1983 Page Two 2. Transportation/Traffic : a . As you recall, we discussed that there was not much sense in upgrading Monster Road to City standards because the future Valley Parkway is planned to be the major arterial in the area and Monster Road a secondary roadway. Therefore , minimal upgrade (resurfacing) to Monster Road would be sufficient and that the Valley Parkway should be the focus of future roadway investments . b . We also discussed the proposed site access from 7th Street to the northeast corner of Metro 's property . Metro desires but does not require this access . It was noted that this access was proposed as a result of past discussions between Metro and the Renton City Fire Chief and in accordance with your access regulations for industrial properties . Metro also desires an alternative site access for employees and sludge hauling. As a point of clarifi- cation, Metro would be willing to participate in the future Valley Parkway to the extent required and to the extent that the Valley Parkway benefits Metro . Again , Metro 's total commitment to the Valley Parkway would have to be related to a direct legal requirement, reduction in other requirements and credit for the 7th Street and Valley Parkway connection/intersection. c . Metro would be willing to participate in area signali- zation that would benefit us as discussed . d . Metro is willing to discuss the City's desire to tie Longacres Drive directly to Monster Road . However , the proposal you presented at the meeting concerns us and we are totally opposed to dedicating existing or future Metro property you identified for street right-of-way . We are willing to discuss it further once we receive a more detailed proposal from you . Again , your proposal would have to be considered in light of other improvements the City requires . . Mr. Richard Houghton March 8 , 1983 Page Three Metro is willing to cooperate in implementing improvements which are requirements by the City 's laws and regulations . We look forward to receiving your written comments pertaining to the conditional use and grading permit applications and appreciate your willingness to expedite the grading permit application . We would also appreciate your providing specific references -to applicable laws and regulations for any improve- ments you plan to impose on Metro. Very truly yours , AA1 Jaws C/b1 David G.

RENTON,WASH.98055 93* RTFD SEPTMO Q BARBARA Y. SHINPOCH MAYOR MEMORANDUM Date: March 4, 1983 - To: Dick Houghton Ron Nelson From: Bob Bergstrom Subject: Metro Treatment Plant Expansion The Department of Public Works Engineering Division has many serious concerns with the Metro Renton Treatment Plant- expansion- project and their lack of addressing City requirements in the phased development. 1.. Internal Plant Fire Protection Metro has an internally-operated- water system fed from a single 8" metered supply into their small 10,000 gallon reservoir. The fire flow capacity is unknown and fire flow testing is needed to adequately evaluate the fire sys- tem performance. 2. New P-1 Channel Bridge - S.W. 7th St. Extension Metro's new haul route for sludge trucks, via S.W. 7th St. , will make Metro liable for latecomer's fees on the two signalized intersections at (a) Powell and Grady Way and, (b) S.W. 7th and Hardie Ave. S.W. The bridge itself should be open for public access, separate technical plan submittals must be pro- vided, and ramped access down to the future P-1 Channel must be provided. The P-1 Channel should be fully excavated through the bridge area to its final design section. Provisions for future signalization of the S.W. 7th St. and Valley Parkway intersection must be provided, and costs for this signal will be shared between Metro and the neighboring Washington Technical Center development. 3. Monster Road Off-Site Improvements Monster Road must be improved to a 36' wide street - with curb and gutter both sides, storm drainage, street lights and sidewalk on one side. 4..• Valley Parkway Off-Site Improvements Because of Metro's vague property acquisition plans on their north property line, this requirement's limits of work are not well defined. However, Metro will have to provide 1/2 of the right-of-way and build 1/2 of Valley Parkway along their north plant frontage. Metro Treatment Plant Ex _=ion 2 - March 4, 1983 This is a major arterial , four travel lanes, with a two-way left turn center lane, curb, gutter and sidewalk with street lighting and storm drainage. Metro's obligation is for 1/2 of the street improvements. 5. Monster Road - Realignment The south end of Monster Road must be realigned to connect directly into Long- acres Drive S.W. This would be a 36' wide road with curbs, gutters, one side- walk and street lighting. This new road would pass through the south edge of the Metro site. 6. Longacres Drive S.W. Off-Site Improvements The north margin of Longacres Drive S.W. , along the Metro frontage must be improved with curb, gutterr sidewalk and street lighting. 7. P-1 Channel and Interim Flood Control The flood control issues are very complex and depend in part if the City can bring the Soil Conservation Service back into the project. Metro's present phase will fill an area outside of their present dike. Com- pensating storage should be provided in the P-1 Channel right-of-way presently controlled by the City of Renton. The Metro plan for a Flood Water Storage Basin on the north portion of their site is not a recommended option. Metro has deeded the necessary channel rights-of-way, but has not firmly com- mitted to accepting their share of the excavated spoils from the P-1 Channel work. Metro's share of the Phase I P-1 Channel is about 165,000 cubic yards. Previous negotiations have only brought theCity some conditional acceptance from Metro to accept their share of this fill . The City needs a firm right-of-entry- agreement from Metro to move ahead with SCS participation. 8. Haul Route Must be Defined Any earth work hauling for this plant expansion must have a haul route defined. Any hauling into Renton from the Seahurst Tunnel must be defined. 9. Sanitary Sewer Service to North End of Plant Metro has no provision for sanitary sewer service connections from the north end of their plant. While Metro has major internal plant sanitary sewers, they are resisting allowing connection from the north. This new connection point to service areas to the north from Washjngton .Technical Center, Container Corp. and other developments up Monster Road are required. gd7R6A9AL REB:jft ti ENVIRONMENTAL REVIEW COMMITTEE AGENDA MARCH 2, 1983 THIRD FLOOR CONFERENCE ROOM: COMMENCING AT 10:00 A.M.

RENTON TREATMENT PLANT ON-SITE EXPANSION ENVIRONMENTAL PROCESS IN COMPLIANCE WITH SEPA ' The environmental impacts of the Renton Treatment Plant on-site , expansion are addressed in the enclosed Final Environmental Impact Statement (EIS) on the Wastewater Management Plan for the Lake Washington/Green River Basins, issued in August 1981. The EIS was prepared by EPA concurrently with facility planning studies undertaken by Metro beginning in 1979. The Plan recommended expansion of the Renton Treatment Plant to 72 million gallons per day capacity and construction of on-site solids handling facilities. The EIS was prepared under the National Environmental Policy Act (NEPA) , and was intended to allow necessary decisions on the plan by agencies with jurisdiction, including EPA, Metro and the Department of Ecology (DOE) . Metro subsequently adopted this NEPA EIS in lieu of a separately prepared SEPA EIS as allowed by WAC 197-10-650 (1) . Metro is acting as lead agency on all parts of the Renton Improve- ment Program for compliance with SEPA, consistent with WAC 197-10-205. The Draft and Final EIS' s were previously supplied to the City of Renton for review and comment. The EIS is enclosed with the current applications for permits for use by the City of Renton in issuing the permits, consistent with WAC 197-10-690 (1) .

FROM: DAVID HEALEY, SEATTLE 1 SUBJECT: MINUTES OF MEETING--AUGUST 5, 1982--CITY OF RENTON Attendees Warren Uhte Brown and Caldwell Dave Healey Brown and Caldwell Ray Drebin Municipality of Metropolitan Seattle (Metro) Dave Hammond Metro g.taMag5..it Building and Zoning Department, City of Renton Gary Norris Public Works Department, Renton Tom Binghaman Renton Police Department Cliff Bates Street Department, Renton Purpose: Discuss site access alternatives for sludge hauling trucks and drainage requirements for relocating existing dikes. 1. Warren Uhte briefly described the proposed solids processing facilities at the Renton plant and what this will mean in terms of large semi-trailer truck traffic leaving and entering the plant each day. Three alternatives access routes were presented: Alternative A--Connection to Southwest 10th Street Alternative B--Connection to Grady Way Alternative C--Connection to Longacres Drive 2. It was agreed that Alternative A was the best alternative since there will be a signalized intersection at Powell and Grady Way. It was brought out that the Grady Way Bridge has a weight limit of 15 tons, which will prohibit sludge trucks carrying 26 tons of wet sludge from using this bridge. This bridge is scheduled to be renovated within 2 or 3 years according to city personnel. 3. Ron Nelson said that it is very likely there will be a drainage channel as planned. Therefore, a bridge will be required for Alternative A. Files August 23, 1982 Page two 4. The Powell and Grady intersection is being financed in part by property developers. Nelson believes that if Metro uses this intersection, the developers may want some Metro partici- pation. 5. Desirability of a connection to Monster Road around the north end of the plant is still in the planning stages . Developers to the north are required to make a tie to Empire Way. 6. Puget Power may develop some property along Grady Way; Metro might approach Puget Power about participation in the roadway. 7. Warren Uhte described proposed changes to the existing dikes. Relocation would remove approximately 9. 9 acres from potential use for floodwater storage. There would be sufficient Metro property outside the dikes to compensate for lost storage by excavating approximately 7 .4 acres to a depth of 3 feet. It was further expalined that at ultimate development all surface runoff from the plant will be diverted to the Green River. 8. City personnel saw no problem at this stage, but suggested that Brown and Caldwell provide full documentation when presenting this proposal to the City Council. 9. Nelson said that if the channel is constructed the. 2 foot3 storage volume per 1 foot developed area requirement may not have to be provided. This will be decided by the Director of Public Works or other officials. 10. Drebin replied that the timing of channel and plant construc- tion may be such that Metro would have to provide the addition- al storage. 11. The city will supply information on bridge standards and development requirements. DH:cp cc: P. Anwar Seattle W.
