xv2019 Comprehensive Solid Waste Management Plan - July 2018
Executive Summary
This Comprehensive Solid Waste Management Plan (Plan) sets strategies for managing solid waste in King County
over the next six to 20 years. Required by the Revised Code of Washington (RCW) 70.95, this Plan will guide actions
by King County, all cities in King County except Seattle and Milton, and private companies that provide curbside
collection and processing of recyclable materials.
This Plan addresses the many public and private components of the regional solid waste system, including:
•The King County Solid Waste Division’s (division’s) operation of the Cedar Hills regional landfill, ten transfer
facilities, nine closed landfills, and many programs to prevent and recycle waste;
•City efforts to promote recycling and provide for curbside pick-up of materials, either as a direct city service
or through contracts with private haulers; and
•Private companies’ collection of materials at the curbside and operation of processing facilities that convert
recyclable and organic materials into marketable products.
Partnerships among system participants are key to the successful implementation of this Plan. In 2018, the final
city signed the Amended and Restated Interlocal Agreement, securing participation of all 37 partner cities through
2040. This milestone reaffirms the county’s responsibility to provide disposal through 2040, allows costs and risks
to be shared across the large regional customer base, and strengthens opportunities to work together to achieve
environmental goals.
This Plan benefitted from extensive public input including nearly two years of collaboration between the division
and its two advisory committees. The input helped the Plan address time-critical service choices facing the
regional system:
Recycling. Waste prevention and recycling are long-standing priorities. Much progress has been made through
expanded recycling options and services, customer education, and other means. However the region’s recycling
percentage still hovers in the low 50s and stronger markets for recyclables are needed in light of factors such
as China’s recent import restrictions on recyclable materials. This Plan offers a variety of waste prevention and
recycling approaches that allow system participants to tailor approaches to their jurisdiction’s needs while
working together to harmonize approaches to achieve better results for the region.
Transfer. This Plan recommends the continued modernization of the transfer system. Station upgrades are
completed or underway in all urban areas (except for Northeast King County) to improve services and meet
future needs. This Plan recommends that the 1960s era Houghton station in Kirkland be replaced with a
modern station so that equitable levels of service are available throughout the urban area including the fast-
growing Northeast part of King County.
Disposal. The Cedar Hills Regional Landfill has provided cost-effective, environmentally responsible waste
disposal for more than 50 years. Built capacity at the landfill will be exhausted in 2028 however, leaving only
ten years to put the next disposal method in place. To meet disposal needs, this Plan recommends further
development of Cedar Hills to maximize disposal capacity, while affirming that garbage shall not be disposed
of, nor shall soils be stockpiled, within 1,000 feet of the property line at the landfill, in accordance with the
Settlement Agreement. To account for technological advances, this Plan does not specify the next disposal
method after ultimate closure of Cedar Hills. Evaluation of future disposal methods will begin before the next
plan update.

Introduction
This Comprehensive Solid Waste Management Plan (Plan) proposes strategies for managing King County’s solid
waste over the next six years, with consideration of the next 20 years. The Plan was prepared by the Solid Waste
Division (the division) of the Department of Natural Resources (DNRP) and Parks in accordance with the Revised
Code of Washington (RCW) 70.95 and in cooperation with its advisory committees - the Metropolitan Solid Waste
Management Advisory Committee (MSWMAC) and the Solid Waste Advisory Committee (SWAC). MSWMAC represents
the 37 cities in King County that are signatories to the Amended and Restated Interlocal Agreement (Amended and
Restated ILA), the foundation of the King County solid waste system. This Plan revises the 2001 Comprehensive Solid
Waste Management Plan (2001 Plan), and builds upon the 2006 Transfer and Waste Management Plan (Transfer Plan).
With this Plan, the division embraces the DNRP’s mission to foster sustainable and livable communities by focusing
on these critical areas: environmental quality, equity and social justice, fiscal responsibility, and economic vitality.
The division is building upon past and current efforts to increase waste prevention and recycling while advancing
green building practices in the region’s communities and within its own operations. The division continues to refine
operational practices and facility designs in ways that further reduce its carbon footprint and promote the greening
of natural and built environments. The participants in the countywide solid waste management system – from the 37
cities within the county’s borders to the private-sector collection and processing companies to individual businesses
and residents – are contributing to these vital efforts in their own operations and practices.

Since its inception in 1969, the core mission of the division has been to ensure that residents and businesses in the
county have access to safe, reliable, efficient, and affordable solid waste handling and disposal services. The last few
decades have brought about significant developments in the management of solid waste, stemming not only from
advances in technology and the changing marketplace, but from a widespread recognition of the importance of
waste prevention, resource conservation, sustainable development and environmental stewardship.
Over time, the management of solid waste has evolved from a relatively simple system of garbage collection and
disposal to a much more complex network of collection, transportation, and processing for garbage, recyclables,
organics (yard waste and food scraps), and construction and demolition debris. This integrated network combines
the infrastructure and services of both the public and private sectors to provide long-term capacity for solid waste
management in the region.
Summary of the Plan Organization
This Plan is organized to guide the reader through the major elements of the solid waste system. Within each chapter
are elements as described below:
Goals reflect the long-term outcomes and aspirations for the regional system. Goals should not change through the
life of the Plan.
Policies provide broad direction and authorization for services and system priorities. Policies should not change
through the life of the Plan.
Actions are targeted, specific, and time-based to implement policies and could include: programs, studies,
infrastructure improvements, and regulations. Actions are built on a foundation of daily service delivery by the county,
cities, and other stakeholders. This Plan does not attempt to describe every solid waste task in the regional system. It
lists only those that are particularly important to initiate or continue. Actions may be updated outside of the formal
Plan update process to adapt to changing conditions. The Summary of Recommended Actions table in each chapter
includes a page number to indicate where information related to each action can be found in that chapter.
Following the table of contents is a list of acronyms, abbreviations, and common terms used throughout the Plan.
A list of the documents referenced in the Plan is provided in Chapter 8. Website addresses are provided for documents
that were prepared by or for the division.
Six appendices are provided with the Plan:
•Appendix A is a cost assessment, as required by the Washington Utilities and Transportation Commission (UTC),
•Appendix B includes the six-year capital improvement plan required to be included in the Plan,
•Appendix C is the Amended and Restated Solid Waste Interlocal Agreement (Amended and Restated ILA),
•Appendix D shows assumptions used in the Waste Reduction Model (WARM) model of greenhouse gas
emissions,
•Appendix E includes the division’s responses to the comments and questions received during the public
review period; the full text of each comment is also be available on the division’s website,

Review Process
State law delegates authority to the county to prepare a comprehensive solid waste management plan in cooperation
with the cities within its boundaries. An interlocal agreement is required for any city participating in a joint city-county
plan (RCW 70.95.080(3)). This Plan was prepared in cooperation with 37 King County cities with which the county has
interlocal agreements (all cities in the county except for Seattle and Milton).
This Plan builds upon the 2001 Plan and the Transfer Plan that was approved by the King County Council in December
2007. This Plan presents goals, policies, and actions in the following areas: the existing solid waste system, forecasting
and data, sustainable materials management, the transfer and processing system, landfill management and solid
waste disposal, and system financing.
On January 8, 2018, the Draft Plan and Draft Environmental Impact Statement (EIS), conducted according to the State
Environmental Policy Act, were released for a 60-day public comment period. The public comment period ended on
March 8, 2018. The division received 68 comment letters from 40 individuals, four organizations, five businesses, four
agencies, one King County Councilmember and 14 cities. During the comment period, the division also held three
open houses and participated in13 stakeholder meetings with varied audiences.
In addition, the division employed a variety of communications tools in the public awareness campaign during the
60-day public review and comment period. These included on-line and in-person opportunities to comment, as
well as printed materials, a cable TV spot, press releases, and a PowerPoint presentation to support presentations to
stakeholders to make people aware of the key topics in the Draft Plan and how they could comment. Key messages
were developed early and were used in all awareness efforts. An on-line tool was also used to offer people a way
to voice their opinions on the three key issues in the Draft Plan. A total of 487 respondents (486 in English, one in
Spanish) participated in the informal on-line questionnaire (KCSWD 2018a).
The revised Plan, transmitted to the King County Council in July 2018, considers comments, preliminary review by
the Washington State Department of Ecology (Ecology), review by the UTC and the Washington State Department of
Agriculture, and incorporates the Executive’s recommendations. The revised Plan must be adopted by:
•The King County Council,
•The Regional Policy Committee acting as the Solid Waste Interlocal Forum (SWIF), and
•Cities representing three-quarters of the total population of the cities that act on the plan during a 120-day
adoption period.
After adoption and completion of the Final EIS the County/City-Approved Plan will be submitted to Ecology.
The Plan becomes final upon Ecology’s approval.
Following is the anticipated schedule for completion of the Plan review and adoption process:

The Existing Solid Waste System
The solid waste management system has evolved from a relatively basic system of garbage collection and
disposal to a much more complex network of collection, sorting, salvage, reuse, recycling, composting, and
disposal managed by the county, area cities, and private-sector collection and processing companies. Initial
improvements to solid waste facilities and
operations have been developed further to
incorporate waste prevention and recycling
programs that strive to balance resource use and
conservation with production and consumption.
One of the early influences in the evolution of
the system was the sweeping environmental
legislation of the 1960s and 1970s, beginning in
1965 with the federal Solid Waste Management
Act, which established strict regulatory standards
for landfills and other solid waste facilities.
Washington State subsequently passed its own
waste management act, codified in Revised Code
of Washington (RCW) 70.95, and established
Minimum Functional Standards for Solid Waste
Handling in the Washington Administrative Code
(WAC) 173-304. In 1976, the federal Resource Conservation and Recovery Act set even more stringent standards
for environmental protection, including requirements for the use of impermeable bottom liners and daily cover
at landfills. In response to the more stringent regulations, the county began closing the unlined community
landfills across the region, replacing many of them with the more environmentally protective and geographically
dispersed transfer facilities that are still in operation today. With the development of the transfer network (eight
transfer stations and two drop boxes) and technological advances at the county-owned Cedar Hills Regional
Landfill (Cedar Hills), division facilities and operations were brought into compliance with the new environmental
standards, and a safe, efficient, and sustainable system of solid waste management was created. The standards
have continued to evolve over time, and transfer facilities and landfills now operate in accordance with the Solid
Waste Handling Standards (WAC 173-350) and Criteria for Municipal Solid Waste Landfills (WAC 173-351).
Thirty-seven of the 39 cities in King County (all but the cities of Seattle and Milton) and the unincorporated areas
of King County participate in the solid waste system. In all, the county’s service area, shown in Figure 2-1, covers
approximately 2,050 square miles. In 2017, there were almost 1.5 million residents and about 771,000 people
employed in the service area, disposing over 931,000 tons of garbage at Cedar Hills. Studies show that even more
can be done to reduce disposal through waste prevention, reuse, and recycling.

The Solid Waste System
Figure 2-2 provides a general overview of the collection, transfer, transportation, processing, and disposal systems
for garbage, recyclables, organics, and construction and demolition debris. Garbage is transported to Cedar Hills for
disposal, while recyclables, organics, and most construction and demolition materials are taken directly to processing
or compost facilities where materials are prepared for sale to manufacturers and other users. As shown, these recycled
or composted products eventually return to the market for consumer purchase.
As can be seen in Figure 2-2, this multi-faceted system uses the combined resources of the public and private sectors.
Regulations and systems for collection, transfer, transport, processing, and disposal that come into play are complex,
involving state, county, city, and private-sector responsibilities.
Collection of Solid Waste and Recyclables
In accordance with state law RCW 81.77.020 and 36.58.040, counties are prohibited from providing curbside garbage
collection services. Legal authority for regulating collection is shared primarily between the state – acting through
the Washington Utilities and Transportation Commission (UTC) – and the cities. The UTC sets and adjusts rates and
requires compliance with the state and local adopted solid waste management plans and related ordinances. RCW
81.77 also includes a process for allowing cities to opt out of the UTC regulatory structure and either contract directly
for solid waste collection or provide city-operated collection systems.
The county’s 2001 Comprehensive Solid Waste Management Plan (2001 Plan)
specifies that recycling should be included as part of the basic garbage rate
for residents in most of King County. King County enacted a service-level
ordinance (King County Code (KCC) 10.18) that includes this requirement
for unincorporated areas, except Vashon Island, Skykomish, and
Snoqualmie Pass. The UTC then required collection companies to develop
tariffs that spread the cost and availability of recycling to all residential
garbage customers. These tariffs and service-level requirements also apply
to cities that have not opted out of the UTC regulatory structure.
Most of the garbage, recyclables, and organics collection in the county’s
service area are provided by four private-sector companies – Recology
CleanScapes, Inc., Republic Services, Inc. (formerly Allied Waste, Inc.),
Waste Connections, Inc., and Waste Management, Inc. Except for Recology
CleanScapes, which only provides contracted services, these companies
operate both through the UTC and service contracts with individual cities.
Most of the 37 cities in the service area contract directly with one or more
of these private companies for collection services. Eight cities (Beaux Arts,
Black Diamond, Covington, Hunts Point, Kenmore, Medina, Woodinville,
and Yarrow Point) and all of the unincorporated areas receive collection
services from these private companies operating under certificates issued
by the UTC. Two cities – Enumclaw and Skykomish – provide municipal
collection services within their own jurisdictions. Enumclaw collects garbage, recyclables, and organics; Skykomish
collects only garbage.
There is a fundamental difference in how the UTC regulates residential and non-residential collection of recyclable
materials. The Federal Aviation Administration Authorization Act of 1994 prohibits regulation of price, route, or service

organics collection is provided by

of any motor carrier transporting property. While this provision does not apply to collection of garbage and recyclable
materials from residents, recyclable materials generated by the non-residential sector are considered to be property
and are subject to a different regulatory structure. King County cannot enact ordinances that require commercial
garbage collectors to include recyclables collection as part of the non-residential collection service. Cities, on the
other hand, may include recyclables collection as part of their non-residential collection service, but cannot prohibit
businesses and other non-residential entities from choosing other vendors for this service.
Revenue Sharing Provides Incentive for Collection Companies to Enhance Recycling
In 2010, the state legislature amended statute RCW 81.77.185, allowing solid waste collection companies regulated by
the UTC to retain up to 50 percent of the revenue paid to them for the recycled materials they collect from households
(the statute does not apply to collection in cities with contracts for recyclables collection). The purpose of the statute is to
provide collection companies with a financial incentive to enhance their recycling programs. Formerly, all revenues from
the sale of residential recyclables were passed back to the households as a credit on their garbage bills.
To qualify for the revenue sharing, collection companies must submit a plan to the UTC that has been certified by
King County as consistent with the current Comprehensive Solid Waste Management Plan. The Solid Waste Division
Director has authority to make this certification.
To qualify for certification, the collection company’s plan must:
•Be submitted annually for approval,
•Demonstrate how proposed program enhancements will be effective in increasing the quantity and quality of
materials collected,
•Demonstrate consistency with the minimum collection standards,
•Incorporate input from the Solid Waste Division, and
•Be submitted to the Solid Waste Division with sufficient time to review prior to UTC deadlines.
Since January 2013, all UTC-regulated areas of King County, except Vashon lsland, have certified revenue sharing
agreements in place.
Curbside Collection in Rural Areas
When curbside recycling was initiated in King County in the early 1990s, the collection companies (operating under
UTC certificates) serving unincorporated areas were required to provide curbside recycling services as specified in KCC
10.18 for most of the county. These requirements, consistent with the 1989 Comprehensive Solid Waste Management
Plan, stated that curbside recycling would be offered to all households as part of the basic garbage service and that
yard waste service would be available to all households as a subscription service. However, some rural areas were
exempted from these requirements because their low population density or lack of participation in garbage collection
services suggested that curbside recycling might not be cost effective.
Currently, three unincorporated areas are not included in the county’s collection service-level standards as specified
in KCC 10.18:

Vashon/Maury Island – Historically, a comparatively high percentage of Vashon/Maury Island residents have chosen
to self-haul garbage and recyclables to the division’s Vashon Recycling and Transfer Station; however, the number of
households subscribing to garbage service has increased over time. Waste Connections, Inc., the company providing
garbage collection service on Vashon/Maury Island, also offers subscriptions to recyclables collection services. From
a survey of Island residents (KCSWD 2016c), about 17 percent currently subscribe to curbside recycling services.
Organics curbside collection is not available.
Skykomish Area – The area around Skykomish is remote and sparsely populated. Residents of Skykomish and
some residents in surrounding unincorporated areas receive curbside garbage collection service from the Town
of Skykomish. Skykomish does not collect curbside recyclables or organics. Customers may self-haul garbage and
recyclables to the division’s drop box facility located in Skykomish; however, separate organics collection is not
provided at the facility.
Snoqualmie Pass – The Snoqualmie Pass area is also very sparsely populated. Residential garbage collection is
available from Waste Management, Inc. of Ellensburg in Kittitas County. Curbside recycling is not available; however;
the division does provide a site with collection bins for the standard curbside recyclable materials. Organics collection
is not available.
Transfer
The division operates eight transfer stations and two rural drop boxes in the urban and rural areas of the county
(Figure 2-3). In addition to meeting standards for the safe and environmentally sound transfer of solid waste, the
transfer network reduces the amount of truck traffic on the highways by providing geographically dispersed stations
where garbage collected throughout the region can be consolidated into fewer loads for transport to the landfill.
Transfer facilities are the public face of the solid waste system. In 2017, county transfer facilities received about
917,650 tons of garbage and recyclables, through more than 952,360 customer visits.
Garbage and, at most facilities, recyclable materials from business and residential self-haulers are accepted at the
transfer station and drop box facilities. The transfer stations also provide accessible drop-off locations for garbage
picked up at the curb by the
commercial collection companies.
From these geographically dispersed
transfer stations, garbage is
consolidated in transfer trailers and
taken to the county-owned Cedar
Hills Regional Landfill in the Maple
Valley area. Recyclable materials are
transported to processing facilities
throughout the region.
Public Health – Seattle & King
County (Public Health) is the primary
regulatory and enforcement agency
responsible for issuing operating
permits for both public and private
solid waste handling facilities. This
includes solid waste, recycling, and
composting facilities. Solid waste Entrance of Algona Transfer Station

handling regulations are codified in the Code of the King County Board of Health, Title 10. The permitting process is
the vehicle by which Public Health enforces the state’s Solid Waste Handling Standards (WAC 173-350) and Criteria
for Municipal Solid Waste Landfills (WAC 173-351). Public Health inspects solid waste handling facilities and has the
authority to take corrective action for noncompliance.
Processing of Commingled Recyclables
While garbage picked up at the curb goes to the county’s solid waste system, the collection companies take the
recyclable materials picked up at the curb to their own facilities for processing. The processing of recyclable materials
into new commodities begins at a materials recovery facility. Materials recovery facilities receive material loads from
collection trucks, remove contaminants from the loads, sort materials to meet the specifications of the end users or
markets, and compact or bale the material for efficient shipping. As the residential collection system has moved to
commingled collection, materials recovery facilities in the region have upgraded their facilities to improve their ability
to remove contaminants and sort materials into marketable commodity grades. Any residuals, or non-recyclable
waste products, from materials
recovery facilities within the
King County service area must
be disposed of at a King County
solid waste facility.
The processing of recyclables
throughout the Pacific
Northwest is currently
handled through the private
sector. Companies that
collect recyclables curbside
are required by contract or
ordinance to deliver them to
recycling facilities. Local facilities
receive recyclable materials from
the region as well as from other
areas of the United States. These
private-sector facilities have
made necessary upgrades over
time to expand processing capacity to
meet demand. The three largest collection companies in King County – Recology CleanScapes Inc., Republic Services,
Inc., and Waste Management Inc., each own a materials recovery facility located within the county , shown in
Figure 2-4, to process most of the recyclable materials they collect. Recology CleanScapes’ materials recovery facility
in south Seattle opened in 2014. Republic’s 3rd and Lander Recycling Center in south Seattle was substantially
redesigned in 2007 to improve its ability to sort commingled materials and in 2008 was upgraded to expand capacity.
Waste Management’s Cascade Recycling Center in Woodinville opened in 2002 and was recently upgraded with a
new sort line. Curbside recyclables collected on Vashon Island are processed at Waste Management JMK Fibers’ Port of
Tacoma facility, which was upgraded substantially in 2013. Table 2-1 shows the address for each facility as well as how
many tons were processed in 2017.

Facilities that process mixed recyclables in King County are subject to regulation by Public Health under the Code of
the King County Board of Health Title 10.12, which adopts the standards of WAC 173-350.
Disposal
Solid waste generated in King County’s service area is disposed at the Cedar Hills Regional Landfill – the only active
landfill in the county. Located on a 920-acre site in the Maple Valley area, Cedar Hills has provided safe and efficient
disposal of the county’s solid waste since 1965. In 2017, the landfill received over 931,000 tons of municipal
solid waste.
Cedar Hills was originally permitted in 1960, at a time
when there were few regulations in place to govern the
design and operation of landfills. Since then, environmental
regulations have become increasingly rigorous, requiring
the placement of an impermeable, high-density
polyethylene liner and clay barrier at the bottom of the
landfill, daily cover (using soil or other approved materials)
over the waste, and frequent environmental monitoring,
among other requirements.
Over time, Cedar Hills has been developed in sequential
stages (or refuse areas) in accordance with the most
current Site Development Plan. The division has invested
considerable effort and resources to upgrade older areas
of the landfill, while designing and operating new areas
to meet or exceed regulatory requirements. Figure 2-5
shows the layout of the landfill, including the boundaries
of the past and active refuse areas as currently permitted.
As shown, Area 7 is the currently active refuse area, and is
expected to operate through 2018 or early 2019. At that
time, operations will transition to the newest refuse area,
Area 8.
The landfill is bordered to the east by Passage Point, a transitional housing development, residentially zoned property
on the east, north, and west, and by property to the south that is zoned for mining, other resource extraction,
and similar uses. State regulation WAC 173-351-140(3)(b) requires a 250-foot buffer between the active area and
residentially zoned property, and a 100- foot buffer between the active area and non-residentially zoned property.

However, a special permit, approved by the King County Board of Commissioners in 1960, specified that a 1,000-foot
buffer be established around the landfill. In the 1960s, landfilling inadvertently extended about
400 feet into a portion of the southeast buffer, but environmental regulations continue to be met in that area and
opportunities to restore the buffer are being pursued. Active use of this buffer zone is currently limited to site access
and other approved uses not directly related to land-filling operations, such as environmental monitoring and
activities at Passage Point.
The landfill has received national recognition for its operations and environmental control systems, which meet
or exceed the highest federal, state, and local standards for protection of public health and the environment. This
complex network of environmental controls includes a collection of pipes, culverts, holding ponds, and other
equipment to manage water and landfill gas, as described in more detail below.
Water at the landfill is separated into two categories for treatment. These are: 1) clean stormwater, and 2)
contaminated stormwater, which includes leachate and other water that has potentially come into contact with
garbage. Leachate is produced when water percolates through the garbage; it is collected in pipes within the landfill
and diverted to lined on-site ponds. In the ponds, the leachate is aerated as a preliminary treatment before being sent
to the King County South Wastewater Treatment Plant in Renton. The bottom liner and clay barrier beneath the landfill
prevent leachate from seeping into the soil or groundwater. Stormwater that runs off the surface of active landfill
areas is also potentially contaminated. It is collected in lined ponds before moving on to the treatment system. Clean
stormwater is diverted to detention or siltation ponds to control flow and remove sediment, and is then discharged to
surface water off-site.
Landfill gas is generated through the decomposition of waste buried in the landfill. The gas consists of about 50
percent to 60 percent methane, with the remainder made up of carbon dioxide and trace amounts of oxygen,
nitrogen, and other gases. Landfill gas from Cedar Hills is collected by using motor blowers to create a vacuum in

Cedar Hills Regional Landfill BEW Public
Climate Change Benefits
Converting previously flared landfill gas into renewable energy means that an equal amount of
non-renewable energy – fossil fuels like natural gas, coal, or oil, do not need to be consumed.
This reduces greenhouse gas emissions by about 82,000 metric tons per year. It also
reduces emissions of air pollutants that contribute to smog and acid rain.
Did you know the Cedar Hills Regional Landfill is one of the largest
landfill renewable energy producers in the United States?
2,550 tons of trash come into
the landfill on average each day. The
decomposing organic material forms
carbon dioxide and methane gases. In
2017, the landfill generated about 10,000
cubic feet per minute of gas.
The gas control system minimizes gas
emissions escaping through the ground
or through the air. The gas is captured
through a network of pipes and sent to
the Bio Energy Washington (BEW)
gas-to-energy plant on site.
Selling biogas produced by the BEW
plant generates $1 - $7 million
annually, depending on production rates
and market prices, helping to keep solid
waste disposal rates low. The renewable
natural gas produced by the plant each
year equals the amount of energy
needed to meet the natural gas needs of
over 19,000 homes in King County or to
substitute for the energy use of
11.2 million gallons of diesel fuel.
The BEW plant, in operation since
October 2010, processes the landfill gas
into pipeline-quality biogas and electric
power. Along with generating
approximately 15.4 million
therms of clean renewable
natural gas each year, BEW
generates over 15 million kilowatt hours
of electricity from landfill gas each year
to help offset the facility’s electricity use.
Residual impurities are destroyed by the
plant’s thermal oxidizer.

perforated pipes within the solid waste. The gas used to be routed to high-temperature flares, where it was burned
to safely destroy any harmful emissions. In a public/private partnership, Bio Energy Washington, began operating a
landfill gas-to-energy facility at the landfill in 2010. The facility runs landfill gas through a series of processors that
remove and destroy harmful components and convert the methane portion of the gas into pipeline-quality natural
gas. The clean gas is routed through a nearby gas line into the Puget Sound Energy grid and is also used to power the
facility (Figure 2-6). The division is also exploring other uses for the gas, such as producing compressed natural gas for
operating vehicles. The flare system is kept in standby mode; during maintenance of the energy facility or in the event
of an emergency, the flare system can be activated to manage the gas. Air emissions from the flare system are tested
regularly and have consistently met or exceeded all applicable environmental regulations.
Solid Waste System Planning
In addition to regulating solid waste handling and disposal, state law also established a framework for planning,
authorizing counties to prepare coordinated Comprehensive Solid Waste Management Plans in cooperation with
the cities within their borders. While cities can choose to prepare their own plans, all of the incorporated cities within
King County, except for Seattle and Milton, have chosen to participate in the development of this single, coordinated
regional plan for the incorporated and unincorporated areas of King County. Since July, 1988, cities have entered
into interlocal agreements (ILAs) with the county that establish the Solid Waste Division as the lead planning agency.
By the time the first Comprehensive Solid Waste Management Plan was adopted by the Metropolitan King County
Council in 1990, there were 29 incorporated cities participating in this coordinated effort. Since then, eight new cities
have incorporated and joined the King County system – for a total of 37 cities.
To make sound planning decisions, it is important to understand how the solid waste system operates today and
to identify changes that might affect it in the future. This information is critical to ensuring that plans for facilities,
services, and programs meet the needs of the region in the years to come. Because the system is a combination of
public and private entities, working with stakeholders in the early stages of system planning is essential. In addition
to working with local jurisdictions and the private-sector collection companies, the division works closely with its two
advisory committees – the Solid Waste Advisory Committee (SWAC) and the Metropolitan Solid Waste Management
Advisory Committee (MSWMAC). For the preparation of this Plan, the division collaborated with the advisory
committees through a process of presentations and discussions.
The next section identifies the participants in the planning process and describes the stakeholder process that guided
the development of this plan. Also included is a brief description of the state, county, and city responsibilities in
planning the solid waste system.
A Regional Approach
As partners in a regional system, cities share in the costs and benefits of King County’s transfer and disposal system.
The regional solid waste system was formally established in King County when the county and cities entered into the
original Solid Waste Interlocal Agreement of 1988. In 2013, the county worked with the cities to amend the original
ILA. The Amended and Restated Solid Waste Interlocal Agreement (Amended and Restated ILA) extends the original
ILA by 12.5 years, from June 2028 through December 2040 (the full text of the ILA can be found in Appendix C). The
longer term will keep rates lower by allowing for longer-term bonding for capital projects. All 37 cities have signed the
Amended and Restated ILA. Cities in the regional system are on the following page:

The Amended and Restated ILA includes several enhancements to the original ILA, including provisions for insurance
and a potential reserve for environmental liabilities. Other changes include:
•Commitment to the continued involvement of the cities advisory group (to be renamed the Metropolitan Solid
Waste Advisory Committee or MSWAC),
•An expanded role for cities in system planning, including planning for long-term disposal alternatives and in
establishing financial policies,
•A dispute resolution process, which includes non-binding mediation, and
•Mitigation provisions for host cities and neighboring cities.
Issues specific to individual jurisdictions, such as the city of Bothell annexing areas in Snohomish County, may require
an amendment to the ILA that addresses that particular concern.
Both the original and the new ILA assign responsibility for different aspects of solid waste management to the county
and the cities. The county is assigned operating authority for transfer and disposal services, is tasked with providing
support and assistance to the cities for the establishment of waste prevention and recycling programs, and is the
planning authority for solid waste. Each city is designated the authority for collection services within its corporate
boundaries and agrees to direct solid waste generated and/or collected within those boundaries to the King County
transfer and disposal system.
Cooperation between the county and the 37 cities in a regional system of solid waste management has allowed
the division to achieve economies of scale that translate into lower fees for system ratepayers. A significant benefit
is the savings realized by being able to extend the life of the in-county landfill for solid waste disposal as a result
of improved recycling rates. Economies of scale will continue to be beneficial once the Cedar Hills landfill reaches
capacity and closes, and the region transitions to a new method of solid waste disposal. The benefits also extend
to the network of recycling and transfer stations that provide convenient, geographically dispersed transfer points
around the county. A regional system can operate with fewer transfer facilities than an aggregation of separate,
smaller systems. The regional system also allows use of individual stations to be balanced to reduce over- or under-
use of any one station. Examples of ways the division may influence station use are: 1) reader boards located at each
transfer station that show what the wait times are at the two nearest stations and 2) the online information available
for each station showing a picture of the inbound queue and the average disposal time after weigh-in at each station.

Regional Authorities and Roles
As defined in RCW 70.95.030, solid waste handling includes management, storage, collection, transportation,
treatment, utilization, processing, and final disposal. Responsibility for solid waste handling in Washington is divided
among the state, counties, jurisdictional health departments, and the cities, as delineated in various legislation,
regulations, and agreements. Table 2-2 lists the responsibilities for each entity, its role, and the guiding legislation.
As shown in the table, the state establishes authorities, minimum standards, and planning requirements, and
delegates responsibility for implementation to the counties and cities.

Stakeholder Involvement in the Planning Process
In the development of the Comprehensive Solid Waste Management Plan, the division sought participation
and input from many sources, including the cities, the division’s advisory committees, the Community Service
Areas (unincorporated area community councils), commercial collection companies, the County Council, division
employees, labor unions, and the public.
In 2004, the Metropolitan King County Council adopted Ordinance 14971 to establish a process for the 37 cities
in the county’s service area to collaborate with the division in the early stages of long-term planning and policy
development. It set the stage for creation of MSWMAC, which consists of elected officials and staff from
participating cities.
MSWMAC and the long-standing
SWAC, mandated by RCW 70.95.165,
have been instrumental in the
development of policies, goals, and
recommendations presented in this
Plan. SWAC has been an advisory
group to the division since 1985, with
a membership that is geographically
balanced and includes King County
residents and representatives from
public interest groups, labor unions,

building blocks that form the basis for this Plan. Collaborative efforts that have helped shape the Plan include:
•Establishing progressive goals for waste prevention and recycling that will further reduce solid waste disposal,
•Conducting in-depth analyses and evaluations of the solid waste transfer system that resulted in the
development and adoption of a major renovation and replacement plan for the transfer system network,
•Conducting subsequent in-depth reviews of the renovation and replacement plan for the transfer network, and
•Evaluating strategies for extending the life of Cedar Hills and beginning to explore viable options for waste
disposal once the landfill closes.
For the current planning cycle, the division met with SWAC and MSWMAC regularly to discuss their issues and
concerns, and hear their perspectives on system planning. The contributions of these committees have been
instrumental in developing the Comprehensive Solid Waste Management Plan. The division’s SWAC and MSWMAC
websites contain background on the committees as well as minutes from their meetings with the division
(http://www.kingcounty.gov/depts/dnrp/solid-waste/about/advisory-committees.aspx).
Trends in Solid Waste Management
Leading the Way in Waste Prevention, Recycling and Product Stewardship
King County continues to gain distinction as a leader in waste prevention and recycling. Together, the division and
the cities work with collection and processing companies and local, state, and national businesses and organizations
to develop the innovative programs and services that give the county its leading edge. Some key program
developments include:
•The addition of acceptable recyclable materials for collection at the curb and at division transfer stations,
•Growing markets for a wider array of materials for recycling and reuse,
•Successful promotions that encourage waste prevention,
•An increase in product stewardship, including optimizing/reducing product packaging and shipping materials,
whereby manufacturers and retailers are assuming responsibility for recycling their products through take-back
programs at selected collection sites across the region,
•Advances in the green building industry, including a focus on creating sustainable housing in
affordable communities, and
•An increase in the number of organizations that accept materials for reuse, such as clothing and textiles, edible
food, and reusable building materials.
With this Plan, the division and its advisory committees set goals to reduce, reuse, and recycle by focusing on specific
waste generators and particular materials or products that remain prevalent in the waste stream. The division is also
moving toward a sustainable materials management approach as a way to strengthen the economy while reducing
the climate effects of materials and harm to the environment. This approach emphasizes the importance of looking
at the full life cycle of materials: design and manufacture, use, and end-of-life. Sustainable materials management is
being promoted by both the U.S. Environmental Protection Agency and the Washington State Department of Ecology
and is discussed in more depth in Chapter 4.

Washington’s legislated system for managing unwanted electronic products and mercury-containing light bulbs and
tubes illustrates the successes that can be achieved when manufacturers, retailers, local governments, and nonprofit
organizations work together on a major initiative. State legislation was passed in 2006 that requires manufacturers
of computers, monitors, and televisions – referred to as e-waste – to provide for the recycling of these products
beginning in January 2009. As a member of the Northwest Product Stewardship Council, the division helped draft
the model legislation that led to formation of the E-Cycle Washington program, which implements this recycling
service at no cost for Washington residents, small businesses, small governments, nonprofit organizations, and school
districts. The division assisted businesses throughout the county to become authorized e-waste collection sites.
Approximately 175,000 tons of e-waste have been collected since the program’s inception. Likewise, the LightRecycle
WA program, which recycles mercury-containing lights, went into effect in 2015.
Expanding the Collection of Recyclable and Degradable Materials
A change in the collection of curbside recyclables has been the transition to commingled (or single-stream)
collection. With this system, all recyclables can be placed in a single, wheeled cart rather than the smaller, separate
bins often used in the past. The single cart system not only makes recycling easier and more convenient for the
customer, it is more efficient for the companies that provide collection service.
In addition, the division and cities have worked with the commercial collection companies to implement curbside
collection of food scraps and food-soiled paper in the yard waste (organics) container. About 99 percent of single-
family customers with curbside garbage collection have access to organics (yard waste and food scraps) collection
service. Only Vashon Island and the Skykomish and Snoqualmie Pass areas, which house less than one percent of the
county’s residents, do not have this service. Studies estimate that over 50 percent of those who set out organics carts
recycle some of their food scraps. The combined food scraps and yard waste are taken to processing facilities that turn
the materials into nutrient-rich compost used to enrich soils.
Building a New Generation of Transfer Stations
Since the approval by the King County
Council in 2007 of the Solid Waste Transfer
and Waste Management Plan (Transfer Plan),
the division has been moving forward on
the renovation and replacement of the
division’s urban transfer stations to update
technology, incorporate green building
features, increase recycling services, and
achieve operational efficiencies. New
recycling and transfer stations include a flat
tipping floor, areas for the collection of a
wide array of recyclables, design features
that reduce water and energy use, and solid
waste compactors. By compacting garbage
prior to transport for disposal, up to 30
percent fewer truck trips are required to
haul the same amount of garbage.Solar panels on the south roof of the Shoreline Recycling and Transfer

In 2008, the division opened the first of five new state-of-the-art transfer stations – the Shoreline Recycling and
Transfer Station. The station has exceeded all expectations for environmental excellence with its innovative design
and green building features. It received the highest possible honor from the U.S. Green Building Council with a
Leadership in Energy and Environmental Design™ (LEED®) Platinum certification. The station has also been the
recipient of 15 recognition awards from national, regional, and local organizations, including the Solid Waste
Association of North America, the American Institute of Architects, the American Public Works Association, and the
Northwest Construction Consumer Council.
Public involvement was a crucial component of the successful design and construction of the Shoreline station.
Throughout the process, the division worked closely with the City of Shoreline, neighboring communities,
environmental groups, and local businesses and citizens to obtain their input on the project.
The facility design and public process for the Shoreline station have set the bar high for the other recycling and
transfer stations approved for construction during this planning period, reflecting:
•How to approach the planning process – incorporating early community involvement,
•How to build them – using the greenest elements possible, and
•How to operate them – pursuing operational efficiencies that reduce fuel, energy, and water use; and increasing
recycling opportunities.
Following the success of the Shoreline Recycling and Transfer Station, construction began on the new Bow Lake
Recycling and Transfer Station. The design of the new Bow Lake Recycling and Transfer Station builds upon the
environmental achievements of Shoreline, with compactors for improved efficiency, water re-use, energy efficient
lighting, and solar panels. Providing capacity for about one third of the system’s garbage, Bow Lake also offers
expanded recycling opportunities. The new recycling and transfer station was completed in 2013 and also earned a
Platinum LEED® certification, as well as other awards of excellence.
The most recent station to be completed, the Factoria Recycling and Transfer Station – opened in late 2017. This
same year, a site was selected for the South County Recycling and Transfer Station (SCRTS) after completion of a Final
Environmental Impact Statement.
The selected site is just north of
the existing station. Design and
construction of the station will take
place over the next several years,
with an anticipated station
opening in 2022.
All new recycling and transfer
stations will meet green building,
safety and environmental standards;
accommodate projected growth
in the region; incorporate best
practices in transfer and transport
operations; and offer a wide variety
of recycling opportunities for
residential and business customers.

Managing Solid Waste Disposal with an Eye to the Future
Cedar Hills is the only landfill still operating in King County. Because use of the county landfill is currently the most
economical method for disposal of the region’s wastes, the division has been extending its useful life. This strategy,
recommended in the Transfer Plan, was approved by the County Council in 2007. In December 2010, the County
Council approved a Project Program Plan enabling the division to move forward with further development of Cedar
Hills. As approved in the Project Program Plan, a disposal area covering approximately 56.5 acres is being developed –
this will extend the life of the landfill to about 2028 depending on a variety of factors, including tonnage received.
The 2001 Plan directed the division to “contract for long-term disposal at an out-of-county landfill once Cedar Hills
reaches capacity and closes.” With this Plan, the division explored a range of options for future disposal. The Plan’s
recommendation is to further develop Cedar Hills to maximize disposal capacity. The next disposal method to
employ after Cedar Hills reaches capacity is not specifed in this Plan, so that the latest technological advances can
be considered. Emerging technologies for converting solid waste to energy or other resources, such as fuels, are in
various stages of development and testing in U.S. and international markets. Some of the technologies are capable
of processing the entire solid waste stream, while others target specific components, such as plastics or organics.
Regardless of which long term disposal option is selected, the transfer system will still be needed to efficiently
consolidate loads. The division will continue to monitor emerging technologies and advances in established disposal
methods, recycling, and waste prevention. Although the Amended and Restated Interlocal Agreement requires
consultation with cities at least seven years before Cedar Hills closes, evaluation of the next disposal method should
begin prior to the next plan update to ensure enough time for method selection, planning, and implementation.
Financing the Solid Waste System for the Long Term
As the division continues to modernize the transfer system, keeping fees as low and stable as possible is a
fundamental objective.
While division revenues rely primarily on per-ton fees for garbage disposal, the current priorities are to increase
recycling and prevent waste generation. Reductions in tonnage due to waste prevention and recycling have been
gradual, and the system has adjusted accordingly. However, further reductions will continue to affect system
revenues. The division will continue to identify new revenue sources, such as the sale of landfill gas from the Cedar
Hills landfill and greenhouse gas offsets from this and other potential sources, and will explore sustainable financing
options. The division will also work with its advisory committees and others to develop and/or revise financial policies,
and address rate stabilization and cost containment. Policies, actions and more discussion can be found in Chapter 7,
Solid Waste System Finance.
Protecting Natural Resources through Environmental Stewardship
Environmental stewardship means managing natural resources so they are available for future generations. It also
involves taking responsibility – as individuals, employees, business owners, manufacturers, and governments – for the
protection of public health and the environment.
Building an environmentally sustainable solid waste management system in King County takes a coordinated, region-
wide effort. The division, the cities, and the collection and processing companies in the region are making concerted
efforts to help make this happen.
Updated April 17, 2019

Ordinance 18893
2-22 2019 Comprehensive Solid Waste Management Plan - July 2018
Waste prevention and recycling are just two of the
ways in which the division and others are working
to reduce wastes, conserve resources, and protect
the environment. Other innovations and well-
established programs that support environmental
stewardship include collecting and selling landfill
gas to be converted to pipeline quality gas,
potential new composting and reuse facilities, and
providing cleanup assistance for illegal dumping.
Additional Planning Considerations
Climate Change
Climate impacts are considered by the division when planning for future programs, facilities, and operations, in
accordance with Washington State’s Solid and Hazardous Waste Plan, Moving Washington Beyond Waste and Toxics
(Ecology 2015) and the county’s Strategic Climate Action Plan (King County 2015b). Climate change is manifest in
the long-term trends in average weather patterns, including the frequency, duration, and intensity of wind and
snow storms, cold weather and heat waves, and drought and flooding. Climate change is attributed primarily to
the emission of greenhouse gases (GHG), including such compounds as carbon dioxide and methane. Planning for
climate change means taking into account both how we might reduce our effects on the climate, today and in the
future, and how changes in climate might affect our facilities and operations.
Against a baseline set in 2007, the Growth Management Planning Council adopted a Countywide Planning Policy
that targets a reduction in countywide sources of GHG emissions of 25 percent by 2020, 50 percent by 2030, and 80
percent by 2050. King County will be responsible for assessment and reporting.
At a regional level, the division and its planning participants continue to strengthen and broaden waste prevention
and recycling programs to continually improve our long-term, positive effects on the environment (discussed in detail
in Chapter 4, Sustainable Materials Management). The benefits are tangible in terms of reductions in GHG emissions,
resource conservation, and energy savings.
King County – Cities Climate Collaboration (K4C)
King County and thirteen cities — Bellevue, Burien, Issaquah, Kirkland, Mercer Island, Normandy
Park, Redmond, Renton, Sammamish, Seattle, Shoreline, Snoqualmie, and Tukwila —
are collaborating through the King County-Cities Climate Collaboration (K4C) to coordinate and
enhance the effectiveness of local government climate and sustainability action. Through K4C,
county and city staff are partnering on: outreach to engage decision makers, other cities, and the
general public; coordination of consistent standards, benchmarks, and strategies; sharing solutions;
funding; and shared resource opportunities.
All King County cities are encouraged to join this effort, which is supporting and enhancing projects
and programs in focus areas such as green building, using and producing renewable energy,
sustainability outreach and education, and alternative transportation.

Considerations of how division activities
and operations might affect climate
change involve both positive and negative
impacts on GHG emissions. If areas where
GHG emissions can be expected to occur
are identified, strategies to mitigate those
emissions can be developed, for example:
•The division contracts with Bio Energy
Washington to turn landfill gas into
pipeline-quality natural gas for the energy
market.
•The division builds facilities (such as the
Shoreline, Bow Lake, and Factoria Recycling
and Transfer Stations) that are more energy
efficient to meet LEED® standards. As
previously noted, two of the facilities have
earned a Platinum rating.
•Garbage compactors, both for solid waste and recyclables, are being installed at all new urban transfer stations,
which will decrease truck trips by up to 30 percent, saving fuel and decreasing emissions.
•In day-to-day operations, the division looks for ways to reduce resource use and increase the use of environmentally
friendly products. Examples of operational practices that reduce greenhouse gas emissions include the use of
compaction to reduce truck trips, reducing idling time, environmentally preferable purchasing, and exploring the
use of compressed natural gas and other low-emitting technologies in trucks and equipment.
•The Food: Too Good to Waste program also helps curb the effects of climate change. Uneaten
food accounts for 23 percent of all methane emissions – a potent climate change contributor.
When food is thrown away, all the water and energy used to produce, package and transport
that food is also wasted. The program educates people about how to plan and prepare meals to
decrease the amount of wasted food.
•The division teamed up with the City of Seattle to produce Greenhouse Gas Emissions in King
County (Stockholm Environment Institute 2012), a report that looked at greenhouse gas
emissions from several different perspectives including undertaking a consumption-based inventory. The inventory
offers a more complete picture of the county’s environmental footprint, taking into account emissions associated
with the production and consumption of food, goods, and services. The report’s research shows that efforts such as
reducing food waste or purchasing sustainable and low-impact products can help to create a broader and deeper
impact on global greenhouse gas emissions.
•The division has planted deciduous and evergreen trees on the Duvall and Puyallup/Kit Corner closed landfills to
create a carbon “sink” by capturing carbon dioxide through the process of photosynthesis.
The division also looks at the potential impacts of climate change on facilities and operations and determines
strategies for adapting to those impacts. For example, the division is using more drought-tolerant plants in facility
landscapes and identifying alternate transportation routes to avoid areas where there may be an increase in
seasonal flooding.

King County – Climate Change
Proper solid waste management plays a significant role in reducing GHG emissions. That role is
recognized by both state and local governments in Washington. In 2015, the Washington State
Department of Ecology (Ecology) issued its plan, Moving Washington Beyond Waste and Toxics (Ecology
2015), which presents a long-term strategy for systematically eliminating wastes and the use of toxic
substances. The 2015 King County Strategic Climate Action Plan (King County 2015b) synthesizes and
focuses King County’s most critical goals, objectives, and strategies to reduce GHG emissions and
prepare for the effects of climate change. It provides “one-stop-shopping” for county decision-makers,
employees, and the general public to learn about the county’s most critical climate change actions.
As documented in the 2011 King County Sustainability Report (King County 2011), GHG emissions from
county operations (for sources other than transit) have stabilized and begun to decline. Building on
these successes, achievement of the county’s long-term targets is ambitious, but achievable.
King County’s overarching targets:
•Communitywide: King County shall partner with its
residents, businesses, local governments, and other
partners to reduce countywide GHG emissions at
least 80 percent below 2007 levels by 2050.
•County operations: King County shall reduce total
GHG emissions from government operations,
compared to a 2007 baseline, by at least 15 percent
by 2015, 25 percent by 2020, and 50 percent
by 2030.
•Department of Natural Resources and Parks Carbon
Neutral Commitment: The Department became
Carbon Neutral in 2016. Both the Solid Waste
Division and the Wastewater Treatment Division
must be carbon neutral by 2025.
Throughout this Plan, ways to reduce impacts on the
climate and adapt to changes that occur are noted.
These actions are grouped in three primary strategies:
Mitigation – directly or indirectly reducing emissions.
Examples include reducing energy use at division
facilities, reducing fuel use, using hybrid vehicles,
distributed composting facilities, using alternative fuels, and promoting waste prevention and
recycling to reduce the mining of virgin resources and emissions from manufacturing and processing
activities. Another example is the conversion of gas collected at the county’s landfill into pipeline-
quality natural gas.

Equity and Social Justice
The division adheres to the King County Equity and Social Justice Strategic Plan 2016-2022 (King County 2016b)
which emphasizes that King County is committed to ensuring that equity and social justice are considered in the
development and implementation of policies, programs, and funding decisions. Equity is achieved when all people
have an equal opportunity to attain their full potential. Inequity occurs when there are differences in well-being
between and within communities that are systematic, patterned, unfair, and can be changed. These differences are
not random; they are caused by our past and current decisions, systems of power and privilege, policies, and the
implementation of those policies. Social justice encompasses all aspects of justice, including legal, political, and
economic; it demands fair distribution of public goods, institutional resources, and life opportunities.
In solid waste system planning, the division examines ways that it may affect equity and social justice through its
programs and services.
• Fair distribution of transfer facilities, services at the facilities, and division resources, such as the community litter cleanup,
school education, and green building programs, helps ensure that everyone has access to services that create safer and
healthier communities.
•The division provides technical assistance to ensure that the benefits of green building strategies, such as lower
energy costs and improved indoor air quality, are available to residents of affordable housing developments.
•In siting new transfer facilities, the division engages communities to ensure equal opportunity for involvement in
the siting process. The division uses demographic data to ensure that these essential public facilities are distributed
equitably throughout the county and that any negative impacts of the facilities do not unfairly burden any
community.
•In addition to translating materials into multiple languages, the division has added a Spanish-language component
to its comprehensive outreach programs. Rather than simply translate existing materials, the division has worked
directly with the local Spanish-speaking communities to create new programs and materials in Spanish that
respond to the questions and needs of these communities, an approach referred to as transcreation.
Adaptation – modifying facilities and operations to address the effects of climate change. Examples
include designing facilities for more severe weather systems (e.g., roofs designed for greater snow
loads), using more drought-tolerant plants in
facility landscapes, and identifying alternate
transportation routes to avoid areas where
there may be an increase in seasonal flooding.
Sequestration – removing carbon dioxide from
the atmosphere and depositing it back into
natural “sinks,” such as plants and soils. Examples
include planting more trees around facilities to
remove carbon dioxide through photosynthesis,
using biochar, and using compost to replenish
depleted soils and promote plant growth.

Green Building and Equity
The goal of the county’s Equity and Social Justice Ordinance is for all King County residents to live in
communities of opportunity. To reach this goal, all communities must be equipped with the means to
provide residents with access to a livable wage, affordable housing, quality education, quality health
care, and safe and vibrant neighborhoods. Green building can play an important role in providing safe,
healthy, and affordable housing, public infrastructure, and commercial facilities, which have historically
not been built to the highest green standards.
There exists a variety of equity and social justice opportunities on any project including: education, training,
apprenticeship, procurement, material selection, contracts, public outreach, public service, community
amenities, communication, indoor and outdoor air quality, economic development, job creation, and more.
King County’s Sustainable Infrastructure Scorecard, the green building rating system used for county-
owned projects not qualified for the LEED® certification, contains a Social Equity Credit as an opportunity
to address equity and social justice issues. The county’s Green Building Team is also working on
additional guidance for capital projects to utilize an equity impact review tool, designed to help project
teams to evaluate how people and places are impacted by an action, and to take into consideration
distributional, process, and cross-generational equity.

The monitoring of solid waste disposal, recycling, and waste prevention, and the forecasting of future trends are
fundamental to system planning. The division routinely collects data about the amount and composition of waste
and recyclable materials in the system, tracks demographic and economic trends that will affect the amount of solid
waste generated in the future, and conducts focused studies to address specific topics, such as markets for recyclable
materials, industry trends, and new technologies.
Forecasts are used to estimate the amount of material expected to be disposed and recycled in the coming years,
incorporating expected growth in population and other demographic and economic trends. This information can
be used to estimate the necessary capacity of division transfer and disposal facilities and associated private-sector
recycling facilities and markets.
Existing data and forecasts form the basis for discussions
with cities and other stakeholders about options for the
future, answering questions such as:
•How much waste are system users currently generating
and expected to generate in the future?
• How can waste generation be reduced?
• What materials can be separated from the disposal stream
and turned into a resource through reuse and recycling?
• Who uses the solid waste facilities and curbside services,
how do they choose those services, how often do they use those services, and what influences their choices?
• What is the best method to provide these services?
• What changes in markets and technologies need to be incorporated into our analysis of options for the future?
Forecasts, planning data, and studies used in the development of this Plan are discussed in the following sections.
Forecasting
The division uses a planning forecast model to predict future waste generation over a 20-year period. Waste generation is
defined as waste disposed plus materials recycled. The forecast is used to guide system planning, budgeting, rate setting,
and operations. The primary objectives of the model are to 1) estimate future waste disposal and 2) provide estimates
of the amount of materials expected to be diverted from the waste stream through division and city waste prevention
and recycling programs. The planning forecast model – a regression model - relies on established statistical relationships
between waste generation and various economic and demographic variables that affect it, such as population,
employment, consumption1 (measured as retail sales, excluding sales), and the tipping fees for garbage at division facilities.

3-2 2019 Comprehensive Solid Waste Management Plan - July 2018
In late 2007, a nationwide financial crisis severely compromised the division’s ability to forecast short-term trends
in the economy. With the collapse of large financial institutions, a downturn in the stock market, a drop in housing
prices and personal income, a jump in the unemployment rate, and a general slump in overall economic activity,
the recession led to the bankruptcy of many businesses and home foreclosures. The effects of these dramatic events
touched every sector of the economy including the solid waste industry.
In 2007, garbage tons received at Cedar Hills surpassed the one million mark, due primarily to steady economic
growth and population increases in the region over the previous few decades. Between December 2007 and
December 2012, however, garbage tons disposed at Cedar Hills declined 20 percent overall. Garbage tons dropped
eight percent in 2008 alone. The City of Seattle, surrounding counties, and jurisdictions in Oregon and California
reported similar or greater declines in tonnage, as did regional recycling firms.
The recession created a great deal of unpredictability in variables used in the division’s forecast model to predict the
short-term (one to five year) trends in solid waste generation. To respond to this uncertainty, the division has adjusted its
approach to forecasting, using a more flexible system of ongoing monitoring. This evolving forecast method involves:
•Monitoring solid waste tons delivered to division transfer stations and the Cedar Hills landfill on a daily basis,
•Regularly checking regional and state-wide economic forecasts (local economic forecasts by the Western
Washington University (former Dick Conway and Associates), King County’s economic forecast, and forecasts by
the Washington State Economic and Revenue Forecast Council),
•Monitoring state-wide tax revenue streams, particularly in the home improvement sector, furniture store sales,
clothing sector, and other key markets, and
•Communicating regularly with other jurisdictions about the trends in their service areas.
This information has been used to forecast short-term tonnage and subsequent revenues for use in critical budgeting,
expenditure control, and management of capital projects over the three-to five-year period.
With the new model established in 2018, the division is able to provide a prediction for disposal for the next ten
years. After ten years, the tonnage forecast uses a long-term growth rate based on historical tonnage (described in
further detail below). The new model also assumes that a years-long Ecology-reported recycling rate of 52 percent is
sustained through 2040.
An additional feature the division included in the new model is an upper and a lower estimate for the tonnage to
be disposed.
The main characteristics of the new model are:
•Main Model
o This uses the tonnage forecast model output to forecast the next 10 years, out to 2028.
o After 2028, a historical trend is used to generate the disposal tons for the years from 2029-2040:
• This annual growth rate is 1.73 percent, and
• This historical trend is based off the disposal growth rate from 1995-2007. This period covers years after
some major changes in the system occurred during the early 1990s (Seattle leaving the system, recycling
changes, etc.) but before the Great Recession so it’s an appropriate time period to use as a steady-state
historical trend.
•Upper Boundary
o This incorporates the aggressive population growth rate provided by the Office of Financial Management
(OFM) into our tonnage forecast model for the next 10 years, out to 2028.
o After 2028, a high growth rate is used to generate the disposal for years from 2029-2040:
• This annual growth rate is 2.91percent, and
• This growth rate for disposal is based on the period from 2012-2017, which has been a period of high
growth since the Great Recession.

o This incorporates the conservative population growth rate provided by the Office of Financial Management
(OFM) into our tonnage forecast model for the next 10 years, out to 2028.
o After 2028, a low growth rate is used to generate the disposal for the years from 2029-2040:
• This annual growth rate is 0.57percent, and
• This growth rate is from 1995-2017, which is the historical trend line plus the Great Recession
and recovery.
Increases in population, employment, and consumption lead to more waste generated. Studies indicate that for the
long-term planning forecast through 2040, the following trends are expected:
•Population2 is expected to grow at a steady rate of one percent per year. Population growth is directly correlated
with the amount of waste generated; i.e., more people equal more waste generated. See Figures 3 -1 for
estimates for population growth in each transfer station service area and Figure 3 -2 for the projected share of
population growth in each service area.
•Employment is expected to increase at an annual rate of two percent. Increased employment activity typically
leads to an increase in consumption and waste generation.
2 Projections for population and employment are based on 2017 data from the Land Use Vision 2 model developed by the Puget Sound Regional
Council (PSRC). Data provided by PSRC are based on U.S. Census and other data sources and developed in close cooperation with the county and
the cities.

Current Data on Regional Waste Generation, Recycling,
and Disposal
Measuring the results of waste prevention and recycling efforts is a complex process. Discussions and data often
focus on recycling and recycling rates, when in fact waste prevention is the number one priority. While programmatic
successes for waste prevention can be assessed qualitatively, it is difficult to measure directly how much waste is
“not created” in terms of tons or percentages. What can be measured more accurately is recycling and disposal
activities. Data for these activities are available through division tonnage and transaction records, reports from the
curbside collection companies, the Washington State Department of Ecology (Ecology), and the division’s waste
characterization studies. Using data on the types and amounts of materials recycled, combined with measures
of waste disposed, the division can evaluate its success in reaching the goals established with each successive
comprehensive solid waste management plan.
Figure 3-4 shows the tons of materials recycled and disposed in 2015 (most recent data from Ecology) by category
of waste generator – single-family residents; multi-family residents; non-residential customers such as businesses,
institutions, and government entities; and self-haulers who bring materials directly to the division’s transfer stations.
More specific information on each generator type (including generators of construction and demolition debris for
recycling and disposal) follows. Recycling data comes from numerous external sources. These are described in more
detail in the section Tracking Our Progress. Note that the scale on each figure varies.
While there has been considerable progress in waste prevention and recycling over the years, there is still room for
improvement. As Figure 3-4 illustrates, the single-family sector provides the greatest opportunity to divert materials
from disposal, with about 260,000 tons of materials disposed in 2015. Single-family residents are recycling more than

56 percent of their waste, but division studies indicate that a large portion of the disposed materials could be recycled
or reused (as discussed in the next section). The multi-family sector generates the least amount of garbage and
recycling of all sectors, but shows a need for improvement in recycling.
The data shows that self-haulers as a group are recycling the smallest fraction of their waste. That may be because
at many of the older transfer stations there is limited or no opportunity to recycle. At this time, however, two of the
division’s urban stations are undergoing, or are being considered for, renovation. A major goal of the renovation plan is
to add space for collection of more recyclables and to build flexibility into the design to allow for collection of additional
materials as markets develop. Adding space for collection of greater amounts and a wider array of materials is expected
to result in higher recycling rates at the transfer stations.
With studies indicating that 70 percent of the waste that reaches the landfill could have been recycled or reused, and
specific data on what those materials are, we can focus on areas that will have substantial influence on the region’s
per capita disposal rate. The following sections address each category of generator and identify some of the more
significant areas for improvement.
Single-Family Residents
Sixty-five percent of the households in the division’s service area are single-family homes. In 2015, these single-family
households recycled on average about 56 percent of their waste. Ninety-six percent of the yard waste and 79 percent
of the paper generated were recycled by this sector in 2015 (Figure 3-5). While food scraps and food-soiled paper
made up over 35 percent of the waste disposed by single-family residents in 2015, recycling of these materials has
increased as participation in the curbside collection program for these materials continues to grow. Considerable
amounts of the standard curbside recyclables – glass and plastic containers, tin and aluminum cans, mixed waste
paper, newspaper, and cardboard – while easily recyclable, are still present in the waste disposal stream.

Recommendations for improving and standardizing curbside collection for single-family residents are discussed in
Chapter 4, Sustainable Materials Management. Other recyclables found in the single-family waste stream in smaller
amounts include scrap metal, textiles, plastic bags and plastic wrap, and some construction and demolition debris, such
as clean wood and gypsum wallboard.
If all recyclable materials were removed from the single-family waste stream, nearly one-third of the remaining, non-
recyclable materials would be disposable diapers and pet wastes.
Multi-Family Residents
Thirty-five percent of the households in the service area are in multi-family complexes. In 2015, the average multi-
family recycling rate in the county’s service area was 21 percent. While this rate is considerably lower than the single-
family rate, overall generation and disposal from multi-family residences is lower and the difference from single-family
recycling rates is less when yard waste (which is minimal for multi-family) is removed from the calculation. As with
single-family residents, the primary areas of opportunity are in recycling food scraps and food-soiled paper and the
standard curbside recyclables, including paper and cardboard (Figure 3-6).
Other materials present in the multi-family waste stream, both recyclable and non-recyclable, are similar to those
found in the single-family waste stream.
It is difficult to track multi-family recycling rates because of: 1) the varied nature of multi-family complexes, 2) the
growth in construction of mixed-use buildings that contain both residential and non-residential units, and 3) the
varied levels of recycling services provided. What is clear is the need to provide adequate space for garbage and
recyclables collection at these complexes and to standardize collection across the county.
A detailed discussion of ways to improve recycling at multi-family and mixed-use complexes is provided in Chapter 4,
Sustainable Materials Management.

Non-Residential Generators
Nonresidential generators – businesses, institutions, and government entities – recycled an estimated 73 percent of
their waste in 2015. Despite having the highest recycling rate of any sector, non-residential generators still present an
opportunity for increasing King County’s overall recycling rate (Figure 3-7). There are an estimated 771,000 employees
in the service area working at an estimated 49,000 businesses and organizations. The make-up of the non-residential
sector ranges from manufacturing to high-tech and retail to food services. The recycling potential for any particular
business or industry varies depending on the nature of the business. For example, restaurants and grocers are the
largest contributors of food waste, while manufacturers may generate large quantities of plastic wrap and other
packaging materials. Because of the diversity of business and industry in the region, a more individualized approach is
needed to increase recycling in this sector.
There are significant opportunities in the non-residential sector to increase the diversion of food scraps and food-
soiled paper. The largest increase will be realized as more restaurants and grocers contract with private-sector
companies to collect their food scraps for composting and more cities begin to offer commercial organics collection.
Another opportunity for reducing overall disposal is with commercially generated paper. While large amounts of
paper are being recycled, almost 40,000 tons of recyclable paper were disposed by businesses in 2015. Paper may also
provide an opportunity for waste prevention – not just moving from disposal to recycling, but aiming to reduce the
generation of waste paper.

Self-haulers
Self-haulers are residential and non-residential customers who choose to bring garbage and recyclables to the
transfer facilities themselves. According to on-site surveys conducted as part of the division’s waste characterization
studies, the two most common reasons given for self-hauling are: 1) having a large quantity of waste or large or
bulky items to dispose, and 2) wanting to avoid the cost of commercial collection. About 37 percent of the materials
disposed by self-haulers have the potential for recycling, most significantly clean wood, yard waste, scrap metal, and
paper (Figure 3-8).
At the older stations and drop boxes where space is limited, the division provides collection containers for the
standard curbside recyclables, which include glass and plastic containers, tin and aluminum cans, mixed waste paper,
newspaper, and cardboard. No recyclables are collected at the Algona Transfer Station due to space limitations. At the
stations that have been renovated and there is more space, additional materials such as textiles, scrap metal, used
bikes and appliances are also collected. Other materials will be collected as markets develop. There are a number of
materials still prevalent in the self-haul waste stream for which there are currently insufficient or no recycling markets,
such as treated and painted wood.
Generators of Construction and Demolition Debris
In 2015, nearly 900,000 tons of construction and demolition debris were generated in King County. Debris from
the construction, remodeling, repair, or demolition of buildings, other structures, and roads includes clean wood,

painted and treated wood, dimensional lumber, gypsum wallboard, roofing, siding, structural metal, wire, insulation,
packaging materials, and concrete, asphalt, and other aggregates.
Clean wood makes up about 24 percent of the construction and demolition debris that is being disposed. Other
recyclable construction and demolition materials that are being disposed include scrap metal, clean gypsum, and
asphalt shingles.
Figure 3-9 shows the composition of construction and demolition materials diverted and disposed in 2015 based
on reports from private processing facilities, Ecology data, and waste monitoring at the division’s transfer stations
(Cascadia 2012a). Most concrete, asphalt, and aggregates are source separated for recycling at jobsites and are not
reflected in these numbers. For more information on construction and demolition debris collection and recycling see
Chapter 4, Sustainable Materials Management.
Tracking Progress
The division uses a wide range of available data, both qualitative and quantitative, to evaluate the success of waste
prevention and recycling efforts. Over the years, the division has developed a robust collection of surveys and data
from a variety of sources to track progress. In most cases, more than one source of data is needed to accurately
quantify how well the region is doing in diverting materials from the waste stream. For example, to track progress
toward a target of 4.1 or fewer pounds of waste per employee per week, the number of employees in the service
area for a given year is divided into the annual tons of garbage generated by the non-residential sector, as reported
Figure 3-9. 2015 Construction and demolition materials diverted and disposed

processing facilities; it does not include aggregate materials that are source separated at jobsites, which comprise approximately 450,000 tons of
asphalt/concrete.

in customer surveys conducted at transfer stations and information submitted to the division by the collection
companies. Using these data, pounds per week can be calculated. The targets are tracked using aggregate data for the
service area, rather than using data by individual city or unincorporated area.
The following subsections provide information on the types of data collected, how those data are calculated, and how
reliable the data are, as well as recommendations on how the data might be improved.
Tonnage and Transaction Data
An automated cashiering system is used to track data on the tons of garbage received and number of customer visits
at division transfer facilities. In-bound and out-bound scales weigh loads for all vehicles except fixed-rate vehicles (as
defined in KCC 10.04.020 MM), which are charged a minimum fee that assumes a weight of 320 pounds or less. These
data are used to track overall garbage tonnage and transactions at individual stations. Data for recyclables accepted
for a fee, such as yard waste, are also tracked by the cashiering system. For recyclables collected at no charge, data are
provided to the division by the hauling company that is contracted to collect them.
Reports from the Commercial Collection Companies
The private-sector companies that provide curbside collection of residential garbage and recyclables throughout
most of King County submit monthly tonnage reports to the division. These reports are also provided to the cities.
Data for single-family households are the most complete, providing the following monthly information for each city
and for unincorporated areas operating under a Washington Utilities and Transportation Commission tariff:
•Tons of garbage disposed,
•Tons recycled by material type,
•Tons of organic materials recycled (yard waste, including food scraps for most areas), and
•Number of garbage, recycling, and organics collection customers.
Generally, customer counts and tonnage numbers for single-family garbage, recycling, and organics are the most
reliable because they are based on weights measured at the entrance scale of either county transfer stations
(for garbage) or material recovery facilities (for recyclables). To estimate the tons of individual materials (such as
newspaper, aluminum cans, and so on), collection companies take periodic random samples and determine the
percentage of each material present in the loads. As overall recycling tonnage is weighed, tons for individual materials
are allocated based on the percentages obtained in the random sampling. The county has worked with the haulers
to develop and implement a standard protocol for sampling in order to provide reliable estimates of the component
recyclables and contaminant materials.
The same information provided for single-family residents is provided for multi-family residents and non residential
generators; however, the per capita data are less accurate because the number of apartment units and business
customers is not provided. In some cases, the same truck collects multi-family and non residential wastes, so collection
companies must estimate how much waste comes from each generator type. Even though some waste may be
allocated to the wrong generator type, overall changes in recycling and disposal are reflected in tonnage totals,
thereby providing a reasonable indicator of change.
Since non-residential recycling collection is open-market and because many companies besides the large hauling
companies provide commercial recycling services, a non-residential recycling rate cannot be calculated from the
collection company data. This means that an overall system-wide recycling rate cannot be calculated using these
data alone.

Ordinance 18893
3-12 2019 Comprehensive Solid Waste Management Plan - July 2018
Ecology Survey Data
Data on the total tons recycled come from the annual statewide survey of recycling companies conducted by Ecology.
These data supplement curbside collection data by including recyclables collected by private sector companies across
the region. Recycling companies are required by state law to report tonnage data on the survey, which asks for tons
by material type, by generator type (residential or non-residential), and by the county in which the materials were
generated. For King County, companies are also asked if materials were generated in the City of Seattle.
The division uses the Ecology survey data to estimate both non-residential and overall recycling rates. All of the recycling
tonnage reported by Ecology is counted as non-residential except for tonnage that was included in residential collection
company reports and recycling tonnage from transfer stations. Use of this accounting method means that recyclables
taken by residents to privately owned drop boxes or recycling centers are included in the non-residential recycling
tonnage. Ecology survey data are also used to estimate construction and demolition debris diversion.
While the Ecology data provide the status of statewide efforts, there are some limitations to the usefulness of the data
for local planning and evaluation, including the following:
•Because data from Ecology is not immediately available, there is about a three-year lag before the county is able
to finalize annual recycling rates,
•Data are self-reported by recycling companies, with few resources available to Ecology for checking accuracy,
•Companies make unverified estimates about the county in which the recyclables were generated, and the
reporting for data between King County and the City of Seattle has been inconsistent, resulting in tonnage
variations from year to year which seem unlikely,
•City-specific information, other than for the City of Seattle, is not available,
•The identification of residential versus non-residential sources is not reliable,
•The identity of some companies that report data is confidential, limiting the ability to verify the quantities
reported, and some of the companies with confidential data report only statewide totals, which requires the
county to estimate allocation based upon population percentages, and
•Significant amounts of metal are reported; it is difficult to determine how much of this metal should be counted
as municipal solid waste, how much as construction and demolition debris, and how much as auto bodies, which
the county does not include in its waste generation or recycling totals.
Improving the reliability of recycling data would greatly benefit our ability to evaluate progress in reaching our
recycling goals. The division will work with Ecology and the cities to develop voluntary agreements with recycling
companies that will improve data reporting and resolve data inconsistencies.
Waste Characterization Studies
Since 1990, the division has conducted a Waste Monitoring Program to understand who uses solid waste system
facilities, what materials they bring to the stations, how and why they use our facilities, and how satisfied they
are with the services provided. To answer these questions, the division retains consultants to conduct both waste
characterization studies and customer surveys that analyze the municipal solid waste received at county facilities
Updated April 17, 2019

for disposal at Cedar Hills. For these studies, the waste stream is examined by collecting and sorting sample loads
delivered to transfer facilities in King County. These studies help the county and the cities understand the composition
of both the overall waste stream and what is received from different types of generators, such as residents of single-
family homes and apartments, non-residential customers, and self-haulers. Separate analyses are conducted of the
construction and demolition debris and organics waste streams.
The waste characterization studies are designed to provide a statistically valid picture of what is being disposed by
the different generator types. Samples are taken over the course of a full year to account for seasonal variations. The
sampling method is designed to ensure that all generator types and geographical areas are sufficiently sampled. The
studies provide a high level of confidence of what is in the waste stream. Each study, described below, is conducted
by the division as necessary to provide up-to-date information for planning purposes.
Solid Waste Characterization Studies
The most recent study of solid waste destined for Cedar Hills was conducted in 2015 (Cascadia 2015a). For this study,
421 samples were collected on 28 sampling days. The waste stream was separated into 97 categories of material. For
each material and generator classification, the study was designed to achieve a 90 percent confidence interval for
the amount of waste disposed countywide. In other words, the study tells us that we can be 90 percent sure that the
amount of cardboard disposed in 2015 was 3.1 percent (26,112 tons) of the total waste stream, plus or minus
0.3 percent.
These waste characterization
studies are not designed to
characterize each city’s waste
stream. However, based on
sampling done in a variety
of communities, the types of
materials disposed by residents
are similar, while the amounts
may differ. For example,
jurisdictions with food waste
collection programs will have
lower percentages of food in
their garbage than those without.
These differences are reflected in
the recycling rates and pounds
disposed per household for each
jurisdiction.
In-person surveys are also
administered to customers bringing materials to transfer facilities (Cascadia 2015a). Customers are asked about the
types of wastes they are bringing, the origin of those wastes, reasons for self-hauling (rather than using curbside
collection services), how often waste is self-hauled, and willingness to separate out various recyclable materials. These
surveys provide a better understanding of the customers who visit the stations and, in turn, provide the proper levels
of service. The surveys are also useful in informing programmatic decisions.

Customer satisfaction surveys are also conducted at the stations to evaluate the level of satisfaction with customer
service and the disposal and recycling services provided at division facilities (Cascadia 2016). The division uses this
information to monitor its performance and identify areas where improvements can be made.
Organics Characterization Studies
Curbside yard waste collection services throughout King County accept food waste (food scraps and food-soiled
paper), and the division is now working to measure how much food waste is actually collected from residential
sources. Reports from the collection companies provide information about total tons of organics delivered to compost
facilities, but do not differentiate between yard waste tons and food scrap tons. The solid waste characterization
studies described above measure decreases of food scraps and food-soiled paper in the waste stream, but not
whether the decreases result from curbside collection or from other diversion, such as home composting.
To improve our ability to measure progress in organics recycling and establish achievable goals, the division is
conducting periodic characterization studies of organics collected at the curb from single-family households. The
division conducted its fourth organics waste characterization in 2017 (Cascadia 2017b) and plans to conduct studies
every two to three years. The study looked at total organics generation, assessing how many food scraps were
disposed in the organics cart and the garbage can. The division has started planning for discussions with stakeholders
to ensure there is adequate organics processing capacity for the materials now being disposed to be processed more
sustainably in the future.
Construction and Demolition Debris Characterization Studies
In 2001, the division began to conduct periodic characterization studies of construction and demolition debris
disposed at select private facilities by commercial and self-haulers, as well as small quantities delivered to division
transfer stations by self-haulers. The studies measure the composition of construction and demolition debris that
continues to be disposed instead of recycled. Three studies have been conducted to date, with the last study
completed in 2011 (Cascadia 2012a). Information from the waste composition studies helped to inform what materials
would be designated as readily recyclable under the new construction and demolition debris recycling ordinance
(see Chapter 4, Sustainable Materials Management for more information).
Planning Tools
To support overall system planning and determine appropriate rates, the division conducts focused studies to
evaluate elements of the solid waste system and its operations, emerging technologies and industry challenges, and
private-sector markets for recycling and reuse. The division will conduct additional planning studies as needed to
explore a variety of topics including best practices in solid waste management, alternative disposal technologies, and
sustainable financing.
Major studies used in development of the Plan are listed on the next page. Plans or studies approved by Council

4-12019 Comprehensive Solid Waste Management Plan - July 2018
In 1989, the state adopted the Waste Not Washington Act, making waste prevention and recycling the preferred
method of managing solid waste and requiring jurisdictions to provide curbside recycling services to all residents
living in urban areas. In King County, the division, cities, Washington Utilities and Transportation Commission (UTC),
and solid waste collection companies worked together to launch a coordinated system for curbside collection of
recyclables throughout the region. Working together over the last almost 30 years, both the public and private
sectors have taken the region well beyond curbside recycling by creating myriad programs and services that foster
the recycling and reuse of materials that might otherwise be thrown away and, more importantly, that prevent waste
from being created in the first place.
Since the 2001 Comprehensive Solid Waste Management Plan was adopted, the collection system in the region has
evolved significantly. The number of materials that can be recycled or processed for recycling and reuse has increased,
technologies for collecting materials have improved, and participation in curbside recycling has continued to climb.
Along with the growth of recycling in the region, however, comes issues that could potentially impact how much and
what materials are recycled. Since inception of the waste reduction and recycling programs, markets and processing
capacity for materials have fluctuated. Recent issues such as China's restrictions on multiple materials markets,
contamination of recyclables and organics, and almost reaching local capacity to process organic materials, are
testing the system’s resilience. Working through these challenges with the cities and local haulers and processors will
ultimately strengthen recycling, collection and processing in the region.
Two key developments have added to the increase of materials collected
in single-family residential curbside recycling in the region. First is the
transition to commingled (or single-stream) collection. Since 2001,
the collection companies have transitioned to commingled recycling,
whereby all the recyclable materials are placed in one large cart for
curbside pickup.
A second development is the addition of food scraps and food-soiled
paper to yardwaste collected curbside. In 2001, the division began
working with cities and collection companies to phase in curbside
collection of food scraps and food-soiled paper in the yard waste
(organics) cart. Compostable food scraps and food-soiled paper, which
currently make up about one-third of the waste disposed by single-family
residents, include all fruit, vegetable, meat, dairy products, pastas, grains,
breads, and soiled paper used in food preparation or handling (such as
paper towels). Food and yard waste, either separated or commingled,
are referred to as organics. Nearly 100 percent of single-family customers
who subscribe to garbage collection now have access to curbside food
scrap collection. Only Vashon Island and the Skykomish and Snoqualmie
Pass areas, which house less than one percent of the county’s residents,
do not have this service.

In addition to these major developments, programs such as Leadership in Energy and Environmental Design™
and Built Green™ are encouraging the building community to focus on waste prevention, recycling, and reuse of
construction and demolition debris and helping to stimulate markets for the recycling and reuse of construction and
demolition materials.
In the 1980s, projections indicated that with the growing population and economy in the region, the amount of
garbage that residents of King County would throw away would continue to climb steeply. Through the efforts of the
county and area cities, businesses, and individual citizens, the amount of garbage disposed per resident per week
dropped from 35 pounds in the 1980s to 15.2 pounds in 2014–a reduction of almost 57 percent. This reduction in
disposal has contributed to extending the life of the Cedar Hills Regional Landfill (Cedar Hills) by more than 20 years.
Yet even with the increased recycling and waste prevention seen over the years, recent waste characterization
studies conducted by the division indicate that about 70 percent of all materials disposed in the landfill are resources
that could have been recycled or reused. As discussed in this chapter, identifying what these materials are and who
generates them can help us determine where future efforts should be focused to achieve ongoing improvements.
Concentrating efforts on a particular class of waste generator (e.g., residential or business) or commodity type
can yield measurable results. Four categories of information, discussed in detail herein, can be used to evaluate
the current status of waste prevention and recycling efforts and help develop strategies that will lead to future
improvements:
1. Waste prevention programs achieving results in the region.
2. Recycling and disposal rates by type of waste generator (discussed in Chapter 3, Forecast and Data), including:
•Single-family (up to 4 units) and multi-family residents (in some cities may include townhomes),
•Non-residential generators, such as businesses, institutions, and government entities,
•Self-haulers, both residents and businesses, who bring materials to division transfer facilities, and
•Generators of construction and demolition debris.
3. Types and quantities of recyclable or reusable commodities that remain in the waste stream, such as food scraps,
clean wood, metals, and paper.
4. The status of markets for recyclable materials, availability of take-back options for used products, and opportunities
to partner with private-sector businesses, national coalitions, and other jurisdictions to effect change.
Information from these four categories was used to shape the goals and recommended actions presented in this
chapter. To set the stage, this chapter begins with a description of the benefits of recycling and a discussion of our
regional goals for the future. From there the focus moves to ways to sustain the momentum by looking at additional
waste prevention, resource conservation, recycling, and product stewardship opportunities. The chapter concludes
with a discussion of the status and challenges of collection by customer type.
Benefits of Recycling Efforts
The regional commitment to recycling has many benefits–financial, social, and environmental. Financial benefits
are probably the most immediate for many county residents and businesses. Convenient recycling services not
only provide an alternative to the higher cost of disposal, but also provide a long-term significant cost savings for
ratepayers by increasing the lifespan of Cedar Hills. As discussed in Chapter 6, Landfill Management and Solid Waste
Disposal, Cedar Hills landfill is a more cost-effective means of disposal than the other disposal alternatives currently
Updated April 17, 2019

available. After Cedar Hills reaches capacity and closes, minimizing the amount of waste that requires disposal will
translate directly into lower fees for King County ratepayers.
The social benefits of recycling can be described in terms of economic growth and job creation. Materials diverted
from Cedar Hills for recycling must be sorted, processed, and transported. The 2016 Recycling Economic Information
(REI) Report (EPA, 2016) includes
information about the recycling jobs, wages,
and tax revenue benefits. The report shows
that recycling and reuse of materials creates
jobs, while also generating local and state
tax revenues. In 2007, recycling and reuse
activities in the United States accounted for:
• 757,000 jobs,
• $36.6 billion in wages, and
• $6.7 billion in tax revenues.
This equates to 1.57 jobs for every 1,000
tons of materials recycled. Construction and
demolition debris recycling provides the
largest contribution to all three categories
(job, wage, and tax revenue), followed by
ferrous metals and non-ferrous metals such
as aluminum.
The positive environmental benefits of recycling are local and ultimately global. Environmental benefits are focused in
two primary areas, both of which have wide-reaching and long-term impacts. First, the release of pollutants emitted
during the production and disposal of products is decreased, reducing the potential for harm to human health and
the environment. Second, savings in energy use and associated reduced greenhouse gas emissions will result from
decreased demand to process virgin materials into products, which also contributes to a healthier planet. Figure
4-1 illustrates a circular supply loop. The figure graphically shows the opportunities, values, and benefits of organics
recycling in King County.
Goal and Targets
The goal and targets for waste prevention and recycling were established through extensive discussions with the
division’s advisory committees: the Solid Waste Advisory Committee (SWAC) and the Metropolitan Solid Waste
Management Advisory Committee (MSWMAC). The countywide goal and targets are intended to improve the
effectiveness of established waste prevention and recycling efforts. The recommended actions for implementation
presented at the beginning of this chapter were developed to provide general strategies for meeting the goal and
targets and to identify the agency or agencies that would lead those efforts. The recommended actions are intended
to serve as a guideline for the county and cities. They do not preclude other innovative approaches that may be
implemented to help achieve the goal and targets.
Factors other than waste prevention and recycling programs and services can increase or decrease the overall amount
of waste generated. For example, the 2007 economic recession resulted in significant, unanticipated reductions in
garbage collected, stemming primarily from the drop in consumer spending and business activity in the region. When
establishing the goal and targets and measuring success in meeting them, it is important to consider the economy,
policy changes, and other factors that may be in play.

Waste Prevention and Recycling Goal and Targets
Overall Waste Prevention and Recycling Goal
Achieve Zero Waste of Resources – i.e., eliminate the disposal of materials with economic value – by 2030
through a combination of efforts in the following order of priority: waste prevention and reuse; product
stewardship, recycling, and composting, and beneficial use.
Waste generation rates to be achieved by 2030
Per Capita – 20.4 pounds/week
This target addresses residential waste from single- and multi-family homes.
Per Employee – 42.2 pounds/week
This target addresses waste from the non-residential sector.
Waste Disposal Targets to be achieved by 2030
Reductions in disposal over time indicate an increase in waste prevention and/or recycling.
Per Capita – 5.1 pounds/week
This target addresses residential waste from both single- and multi-family homes.
Per Employee – 4.1 pounds/week
This target addresses waste from the non-residential sector.
Waste Prevention Targets
Establishing waste prevention targets and measuring success in achieving them is a challenge, because data
quantifying the amount of waste not generated is difficult to obtain. However, by tracking overall waste
generation (tons of material disposed + tons recycled) over the years, King County can attempt to identify regional
trends in waste prevention. A decline in waste generation means that the overall amount of materials disposed
or recycled, or both, has been reduced. The county also uses data from reuse and repair, building salvage,
commercial food waste prevention grants, catalog/junk mail/phone book opt-outs, and material efficiencies
spurred by product stewardship, to help determine whether waste prevention progress is being made.
Recycling Target
Recycling will continue to be an important strategy to reduce the disposal of solid waste. The recycling goal
combines single-family, multi-family, non-residential, and self-haul recycling activity. It addresses the amount
of waste being diverted from disposal at the Cedar Hills Regional Landfill to recycling. It does not include
construction and demolition debris (which have separate recycling goals), or other wastes, such as car bodies,
which are not typically handled through the county system. In 2015, the overall recycling rate for the county
was 54 percent.
The goal for this planning period reflects the estimated recycling rate achievable if the recommended
strategies in this plan are fully implemented (see Figure 4-3).
Overall interim recycling goal: 70 percent

What is Your Recycling Rate? It Depends on What You Count.
Currently, there are no state or national standards for what should be counted in the “recycling rate”
for a city or county. As a result, recycling rates reported by various jurisdictions may include different
materials. For example, the recycling rate reported by some jurisdictions includes many materials
that are not managed as a part of the county's system, so they are not included in establishing the
county's recycling rate. This includes construction and demolition debris, asphalt and concrete,
auto bodies, and biosolids. Many of these materials are very heavy and can considerably increase a
recycling rate based on tons. In addition, some jurisdictions add percentage points to their recycling
rate to account for the estimated success of their waste prevention efforts.
The division has chosen to calculate King County’s recycling rate based on the known amount of
materials diverted from disposal at the Cedar Hills Regional Landfill. As such, it does not include
materials such as construction and demolition debris or car bodies that are handled largely by the
private sector. Neither does the division include any estimate of waste prevention, primarily because
of the lack of measurable data.
For example, based on the definition above, the county’s recycling rate in 2014 was 52 percent.
Adding recycled asphalt and concrete would raise the calculated rate to approximately 62 percent.
The rate would have been higher still if hard-to-measure materials such as car bodies and land
clearing debris were added.
Given the various methods for calculating a recycling rate, it is important to understand what
materials are being counted before comparing rates across jurisdictions.

As can be seen in Figure 4-2, the recycling rate has stalled, even as waste generation has increased in recent years. The role
of individual cities will be critical in reaching our countywide waste prevention and recycling goal and targets. The way
in which each city contributes to the overall goal and targets, however, may vary depending on the city’s demographic
make-up and other factors. For example, a city with a large concentration of apartments and condominiums might focus
more efforts on programs for multi-family residents.
Communities with primarily single-family homes
might focus education and promotion on food scrap
recycling for their residents.
Another factor cities may consider is the make-up
of their business (or non-residential) sectors. Cities
with many restaurants, grocers, or other food-
related businesses might look at ways to promote
the recycling of food scraps or to partner these
businesses with local food banks to donate surplus
food to those in need. Similarly, cities with booming
construction activity may want to take advantage of
markets for the recycling and reuse of construction
and demolition materials.
Likewise, the county will consider the make-up of
the unincorporated area in which to focus waste
prevention and recycling efforts.
The county and the cities lead by example to improve waste prevention and recycling in their respective operations,
at their facilities, and at sponsored events, for instance:
• Some cities have held their own zero waste events and picnics,
• The county and many cities collect food scraps and food-soiled paper at their offices and associated sites, and
• The county enacted an ordinance to purchase copy paper that is 100 percent recycled content and reduce paper
use by 20 percent.
Figure 4-3 provides an example of how the region could reach a 70 percent recycling goal by collectively
implementing mandatory recycling programs.

Tools Used to Meet the Recommended Goal and Targets
The division and the cities have various tools at their disposal to promote waste prevention and increase recycling.
Table 4-1 below identifies these tools and cites some of the successes achieved through their use.
Table 4-1. Examples of successes achieved using various tools
Tool Application Successes
Infrastructure
Establishing the collection and
processing infrastructure is always
the first step. It can be accomplished
through enhanced curbside collection
services, additional recycling options
at transfer facilities, and partnerships
with private-sector processing facilities
and manufacturers/retailers, e.g., to
develop take-back programs.
New transfer facilities are being designed with dedicated areas for
recyclable materials such as yard waste, clean wood, and scrap metal.
Approximately 99 percent of single-family curbside collection customers
have access to collection service for food scraps and food-soiled paper,
along with the yard waste.
Through E-Cycle Washington electronics manufacturers have developed a
statewide network of locations for recycling televisions, computers, and
monitors. Likewise LightRecycle Washington established a network to
collect mercury-containing lights.
Education and
promotion
Educational programs and targeted
advertising play a key role in initiating
new programs and sustaining the
momentum of existing programs.
These efforts can be tailored to specific
waste generators or materials.
The division’s Green Tools team provides education, resources, and technical
assistance on how to manage construction and demolition debris as a
resource rather than a waste.
Many cities provide assistance to businesses to establish and maintain
recycling programs. EnviroStars Green Business Program is a free program
that offers rebates, resources, and incentives to businesses who take action
to protect the environment and employee health and safety. Bellevue,
Kirkland and King County are founding members.
Incentives
Incentives encourage recycling.
For example, in a pay-as-you-throw
(or variable rate) type program, if a
customer generates less garbage, they
need a smaller garbage container, which
means a lower charge on their garbage
bill. Incentives can also take the form
of a give-away item that makes waste
prevention and recycling easier.
To encourage waste prevention and recycling, curbside garbage collection
fees increase with the size of garbage can that customers subscribe
to creating a “pay as you throw” (or variable rate) system. In addition,
embedding recycling in the rate can also act as an incentive.
Some cities provide kitchen containers and sample compostable bags to
encourage residents to recycle their food scraps.

Tool Application Successes
Mandates
Mandates that restrict the disposal of
specific materials have proven effective
in increasing recycling, particularly in
instances where there is a viable and
developed recycling market for those
materials. Mandates can be legislated
at the local, state, or federal level, or
implemented through city contracts.
In order to discourage disposal of yard waste, its disposal in curbside
garbage has been prohibited since 1993.
In 2005, fluorescent lights and many electronics were prohibited from
disposal at King County transfer stations to encourage the recycling of
these items and use of the Take It Back Network
http://www.kingcounty.gov/depts/dnrp/solid-waste/programs/take-it-back.
aspx.
To increase recycling, the division requires self-haulers to separate their
materials at county transfer stations. Starting in 2018, cardboard, metal,
yard waste, and clean wood is banned from disposal at transfer stations
that provide recycling services for these materials.
Enforcement
Enforcement of program rules ensures
that materials are recycled or disposed
of properly.
The construction and demolition debris program employs a King County
sheriff to enforce the recycling and disposal rules for construction and
demolition materials. Outreach and progressive fines are issued to violators
to encourage them to learn how the materials should be handled.
Partnerships
Partnerships enable a program to
be amplified by bringing in other
organizations or agencies to assist with
the program
Product stewardship efforts rely on partnerships to implement programs.
The division routinely partners with other organizations to further product
stewardship goals through the Northwest Product Stewardship Council.
The successful diversion of residential yard waste from disposal exemplifies the effective use of four of these tools.
First, an infrastructure was created to make it easy to separate yard waste from garbage. Curbside collection
programs were implemented in phases across the county, easy-to-use wheeled collection containers were provided
to residents, and private-sector businesses began turning the collected yard waste into compost for building healthy
soils.
Promotions were used to inform residents of
the availability of curbside collection as the
service was phased in. Educational campaigns
were launched to teach citizens how to compost
yard waste from their own yards for use as a
soil amendment. Because the cost of collecting
yard waste for composting was less than the
cost of disposal in the garbage, residents had an
incentive to subscribe to yard waste collection
service. Many cities provided an additional

incentive by including yard waste collection as part of their basic package of collection services at the curb. Finally,
mandates were passed by the cities and the county to prohibit residents from disposing of yard waste in the garbage
wherever separate curbside yard waste collection was available. The resulting collection system for yard waste
successfully recycled almost 96 percent of the yard waste disposed by single-family residents in 2015.
Taking a Sustainable Materials Management Approach
The following discussion describes a different way to look at the waste prevention and recycling programs and
activities already in place. It describes the advantages of a sustainable materials management approach that
encompasses the full life-cycle of materials: design and manufacturing, use and reuse, and end-of-life.
Figure 4-4 graphically depicts the sustainable materials management approach. This approach has been adopted by
the U.S. Environmental Protection Agency (EPA) as well as the Washington State Department of Ecology in the last
update of the state solid waste plan (Ecology 2015). Sustainable materials management still focuses on recycling and
disposal, but by including production, design, use, and reuse, it provides an opportunity to identify more resilient,
sustainable ways to design products that prioritize durability and recyclability, and use less energy, water, and toxics.

Decisions to reduce waste can be made at several critical stages in a product’s life cycle, helping to develop a circular
supply loop:
• When manufacturers decide what goods to produce, how to design them, how to produce them, and how to
package them,
• When consumers decide whether and what to purchase, and
• When consumers adopt ways to use and reuse products more efficiently.
The following sections provide examples of programs in the different phases of sustainable materials management.
Design and Production
Food: Too Good to Waste – This program educates consumers on ways to prevent wasting food. When food is
wasted, it also wastes all the water and energy used to produce, package and transport it from the farm to table. In
addition, about 33 percent of the single-family garbage disposed at Cedar Hills is food, which significantly reduces
landfill capacity and life.
Green Schools Food Waste Reduction and Food Share - The King County Green Schools Program assists schools
and school districts to reduce wasted food through a number of strategies:
• Encourage students to take what they will eat and eat what they take,
• Set up cafeteria share tables on which students may place or take unopened, packaged foods and drinks from
the school lunch program, and
• Donate unopened, packaged items and uneaten whole fruits that cannot be re-served to students.
The goals of the School Food Share program are to minimize wasted foods and beverages and safely distribute
unwanted items from school lunch programs to local food banks and meal programs.
Use and Reuse
Threadcycle is a public education
campaign sponsored by King County and
Seattle Public Utilities that encourages
residents to donate used clothing, shoes,
and linens for reuse or recycling. Local
thrift stores and other organizations are
partners in the program and will take all
clothing, shoes, and linens regardless
of condition (except items that are
wet, mildewed, or contaminated with
hazardous materials).
The EcoConsumer public outreach
program sponsors Repair Groups and
events. Each repair event or group
operates differently, based on the needs of
the local community. It might be a one-time event, or they may be held every few months. People can bring to these
events household items including small furniture, small appliances, personal electronics, and clothing that need to be
repaired. Experienced all-purpose fixers and sewing fixers will work on the items, and can also help residents to learn
to do their own repair.
Repair Group event provides an opportunity for residents to bring in broken
items for repair

End-of-Life Management
Product stewardship is a life-cycle approach that is being implemented at the state, national and international levels.
In practice, the product manufacturers – not government or ratepayers – take responsibility for their products “cradle
to cradle.” This means that manufacturers are given the authority to finance and provide for the collection, recycling
and/or proper management of their products at the end of the product’s life cycle.
Waste Prevention, Recycling and Climate Change
The purchase, use, and disposal of goods and services by King County residents, businesses, and
governments are associated with significant greenhouse gas (GHG) emissions. Emissions can occur
at all stages of a product’s life – from resource extraction, farming, manufacturing, processing,
transportation, sale, use, and disposal. In 2008, consumption-related GHG emissions in King County
totaled more than 55 million metric tons of carbon dioxide equivalents (MTCO2e) – more than
double the emissions produced within the county’s geographic boundaries (King County 2012).
As a major employer and service provider in the region, King County government is also a major
consumer of goods and services. These goods and services – especially construction-related
services – account for 270,000 MTCO2e, or about 42 percent of the County’s operations-related GHG
emissions (King County 2012).
Residents, businesses, and governments can reduce GHG emissions associated with goods and
services by choosing sustainable options, reducing the amount they purchase, reusing and repairing
goods when possible, and recycling after use. King County is involved in these efforts through the
solid waste management services and procurement efforts that the county provides, as well as
through the county’s efforts to educate residents and businesses about ways to use less and recycle
more. The county is also taking a number of steps to reduce the environmental footprint of the
products used in government operations and to reuse previously wasted resources.
Recycling outreach – The Solid Waste Division’s Recycle More – It’s Easy to Do campaign promotes
basic recycling of curbside materials, food scraps and yard waste. Other programs that support
increased recycling and waste prevention include the Green Schools Program, which supports
conservation in schools.
Recycling infrastructure – In King County in 2010, about 832,000 tons of recyclable materials were
collected by private hauling companies at the curb and about 10,000 tons were collected at King
County transfer stations. Turning this waste into resources resulted in the reduction of approximately
1.6 million MTCO2e of GHG emissions.
Reusing resources – King County is helping develop, expand, and support markets for reused and
recycled products. The LinkUp program has expanded markets for recyclable and reusable materials
such as asphalt shingles, mattresses, and textiles. The EcoConsumer program has expanded reuse by
promoting and supporting tool lending library projects in the county.

The division is on the steering committee of the Northwest Product Stewardship Council (NWPSC) and has been
participating in the development of product stewardship strategies for commodities that contain toxic materials or
are difficult and expensive to manage, such as paint, carpet, mercury thermostats, rechargeable batteries, mattresses,
junk mail, and telephone books.
The division and NWPSC were instrumental in getting state legislation adopted to implement the E-Cycle Washington
and LightRecycle Washington extended producer responsibility programs. Both programs provide drop-off sites for
consumers to take their electronics and mercury-containing lights. The division also worked to get a secure medicine
return program implemented in King County. The program started in February 2017, and has approximately 100
locations where residents can securely dispose of unused medications.
What do I do with...? Hundreds of thousands of visitors use this application annually to find recycling, reuse, and
disposal options. Businesses and organizations maintain their listing of the materials and products they recycle, reuse,
or dispose of as a requirement of being included as a partner on this high traffic division website. One of the oldest
recycling databases in the country, What do I do with...? has evolved over almost twenty years from a printed paper
directory to a modern, mobile friendly application. The most searched-for materials are consistently: Appliances,
Batteries, Construction / Demolition Debris, Electronics, and Furniture. The division constantly seeks to refine and
improve the What do I do with...? website, which currently provides information on over 100 materials.
Turning Wastes to
Resources
In 2004, King County adopted “Zero Waste
of Resources” as a principle designed to
eliminate the disposal of materials with
economic value. Zero Waste does not
mean that no waste will be disposed; it
proposes that maximum feasible and
cost-effective efforts be made to prevent,
reuse, and reduce waste. The division
has been taking steps to eliminate the
disposal of materials that have economic
value and for which there are viable
markets.
King County’s list of designated
recyclables is defined and updated by
Ecology’s annual statewide survey of
materials that have been recycled in
Washington. The current list is shown in

While the list of recyclable materials is extensive, available markets and infrastructure can vary from region to region.
The division prioritizes materials for recycling in King County based on four key factors:
• The amount present in the waste stream,
• The ability to handle the material – both collection and processing,
• Viable and sustainable markets for the material, and
• Environmental considerations.
These factors are also used to determine the appropriate method for capturing the materials, i.e., through curbside
collection or at county transfer facilities. The division may also consider other technologies such as anaerobic
digestion or demonstration projects of other evolving technologies that promote resource recovery as ways to recycle
or reuse materials. Since the 2001 Comprehensive Solid Waste Management Plan was issued, the list of materials that
are being recycled has grown substantially.
In 2017, over 931,000 tons of solid waste were disposed at Cedar Hills. As shown in Figure 4-5, at least limited options
in the market exist for the recycling of about 70 percent of the materials disposed.
For years, the Pacific Northwest has relied almost exclusively on exporting recyclable paper and plastics to China
for processing. In early 2018, however, China made the specification for contamination so low (0.5 percent) that
it is extremely difficult to meet, essentially banning the import of 24 recyclable commodities, including unsorted
paper and mixed #3 - #7 plastic. Recyclable materials entering recycling facilities may be contaminated for a variety
of reasons, including commingling the materials in one bin, new packaging types, and resident confusion. Some
materials being collected as part of the approved recyclables list have no markets, contaminate other valuable
recyclable material, and/or create problems in the processing system (examples include plastic bags, poly-coated
paper, cartons and aseptic packaging). China's ban is intended to crack down on illegal smuggling of foreign waste
brought in under the guise of recycling, improve environmental quality, and reduce the volume of contaminated
recyclables legally brought into the country.
In response, agencies, cities, and haulers in King County have formed the Responsible Recycling Task Force (Task
Force). The Task Force will identify common ground for advancing recycling given China’s restrictions on acceptable
recyclables, focusing on short-, mid- and long-term actions. Tenants of responsible recycling include:

•Create domestic demand for recycled feedstock,
•Understand that responsible recycling is not free, and
•Shift to measure recyclables that are made into new products.
While this issue presents a policy challenge for the region, it offers an opportunity to improve on recycling in the
region, reeducate the public on recycling best practices, reduce contamination, and reinforce waste prevention
messaging.
Priority Materials
The following sections describe priority materials identified by the division for recycling through curbside collection
and at county transfer facilities.
Priority Materials for Curbside Collection
Over time, new materials that can be efficiently and cost-effectively captured for recycling are added to curbside
collection programs. Adding materials for curbside collection requires sufficient infrastructure for collection and
processing, and viable and sustainable end use markets. Standardizing the materials collected across the county
simplifies recycling education, reduces confusion among consumers as to what is recyclable, and increases collection
efficiency. However, all materials listed as priorities are not required to be recycled in all city programs.
When the 2001 Comprehensive Solid Waste Management Plan was adopted, materials collected at the curb included
newspaper, cardboard, mixed paper, plastic bottles, tin and aluminum cans, glass bottles and jars, and yard waste.
Materials added since that time include food scraps and food-soiled paper; aerosol cans; small scrap metal; plastic
jugs and tubs; plastic plant pots, trays, and clamshells; plastic and paper drink cups; and aseptic containers.
Organics
More than one-third of what gets disposed at Cedar Hills landfill is food scraps and food-soiled paper. Collection and
processing of these food scraps is critical to meet the county's ambitious waste diversion targets and climate change
goals. There is also a growing effort to capture a large portion of the food scraps that are still considered to be edible.
A recent division study of service management businesses and restaurants in King County (Cascadia 2017b) estimated
that approximately three-quarters of the food scraps these businesses generated was edible food. Significant
opportunities remain to reduce and prevent the tons of food scraps that are disposed.
Commercial haulers throughout King County offer organics collection to both residential and commercial customers.
Nearly all single-family households (99 percent) in King County have access to curbside organics collection that
includes food scraps and food-soiled paper products. Unpackaged food scraps and approved compostable
paper products can be collected along with yard waste in the same containers. King County and many cities have
implemented public education and outreach campaigns to promote and increase participation in food scrap

diversion through curbside organics collection. The division also funded a grant program to promote commercial
food scraps recycling. While participation rates appear to be increasing, there remains room for improvement.
Challenges to food scraps collection include customer access (such as at multi-family residential units where organics
collection is not required or offered by property management), participation levels in diversion programs, political
and institutional barriers, and the level of contamination of the organics collected. As collection of organics increases
it will be essential to ensure adequate regional processing capacity and reduced contamination of material. The
division is actively working with regional partners to:
Engage in long-range planning to increase organics processing capacity,
Encourage greater use of compost, and
Encourage operational changes at processing facilities to mitigate impacts on the surrounding community.
Priority Materials for Collection at King County Transfer Facilities
The division has identified several priority materials to collect at all transfer stations once they are renovated or replaced:
• Yard and wood waste,
• Cardboard,
• Clean wood (not treated or painted), and
• Scrap metal.
Some materials designated for curbside collection and/or as priority materials for transfer station collection are also
collected by private-sector businesses.
Markets for Recyclable Materials
LinkUp – Expanding Markets for Recyclable
and Reusable Materials
Market development is an important strategy to ensure that recyclable
materials are successfully moving from waste to resource. The division
is working to expand markets for recyclable and reusable materials
and facilitate the infrastructure that supports those markets, through
its LinkUp Program. Working with businesses, public agencies, and
other organizations, LinkUp develops projects that address specific
market barriers (from collection to processing to end-use) that prevent
or restrict a material or product from moving up the value chain for
ultimate reuse or use as a raw material for manufacturing new products.
In recent years, LinkUp has conducted projects to improve markets for
asphalt shingles, carpet, mattresses, compost, and textiles. Projects
have supported efforts, such as the development of collection and
processing infrastructure for asphalt roofing shingles, carpet, and
mattresses; establishment of the hot mix asphalt pavement market for
asphalt shingles; expansion of the Take it Back Network to include latex
paint, and promotion of the network to the public; public education
to promote donation of damaged textiles for reuse or recycling; and
demonstration of the use of compost for agricultural applications by King County farmers.
Developing markets for asphalt shingles
has been one focus of the LinkUp program.

2015 and 2017 Market Assessments
In 2015 and 2017, Cascadia Consulting Group conducted market assessments for the division that focused on
commingled curbside recyclables, organics, electronics, film plastics, and construction and demolition materials
(Cascadia 2015b and Cascadia 2017).
First, Cascadia conducted a preliminary analysis and ranking of potential focus materials. Evaluation metrics included
disposed tons, disposed volume, GHG emissions if recycled rather than landfilled, ability to influence the county’s
recycling rate, and market strength. Table 4-3 shows the results of the preliminary analysis and ranking.

Cascadia then conducted “mini assessments” of the top six ranked materials, combining two categories of electronics,
and excluding textiles and mattresses, for which the division already has market support efforts underway. Findings
from these studies, which looked at the material supply for recycling, processing capacity, and current markets,
included:
•Markets for commingled curbside recyclables, including paper, plastics, glass, and metals were generally stable
in 2015. However, China’s 2018 implementation of their “National Sword” policy to restrict the importation of
mixed paper and mixed #3-#7 plastics has resulted in the immediate closure of a significant market for these
recyclable materials. Annually, around 138,000 tons of these recyclable materials from King County that would
normally go to China now need to be processed elsewhere. At this time, alternative export and domestic
markets for mixed paper and mixed plastics are extremely limited. Food scraps and plastic film/wrap are the
biggest contamination challenge in curbside commingled recycling.

•Almost all organic materials collected within the King County system are being converted into compost
products, which are primarily used as soil amendments. Anaerobic digestion (a biological process that
transforms organic waste into renewable energy, and in some situations, a useable residual by-product) is an
emerging processing technology in the region. More organics processing capacity is likely needed if there are
to be significant increases in food scraps and food-soiled paper composting in King County and surrounding
regions (See Chapter 5 for more information about processing capacity). Market prices and sales of compost
products are reported to be stable. Expanding agricultural compost markets is of interest.
•Wood and plastic films have significant barriers to successful recycling. Wood markets are stable but weak and
highly dependent on use as hog fuel. Barriers to plastic film recycling occur at all points of the supply chain.
Grants to Cities
Waste Reduction and
Recycling Grants
The division provides grant funds and
technical assistance to cities to help
further waste prevention and recycling
programs and services within their
communities. Each year, King County
distributes over $1 million in grant funds
to cities; these funds are supported by
the solid waste tipping fee. All cities in
the service area are eligible for the funds.
The formula for their allocation includes a
base amount plus a percentage based on the city’s population and employment.
Currently, much of these grant funds is used by the cities to hold recycling collection events in their communities.
The cities and the county may be able to phase out these collection events and use the funds in other ways that
support waste prevention and recycling in their communities as enhanced recycling services are added at renovated
transfer facilities, curbside collection for bulky items becomes more cost effective and widely available, and product
stewardship programs begin to offer more options for recycling. The grant monies can be used to support a number
of activities, including:
•Encouraging and promoting waste reduction,
•Continuing to implement and improve general recycling programs,
•Improving opportunities for the collection of specific commodities, such as paper,
•Improving opportunities for the collection and/or composting of organic materials,
•Increasing the demand for recycled and reused products,
•Fostering sustainable development through the promotion of sustainable building principles in
construction projects,
•Managing solid waste generated by public agencies in a manner that demonstrates leadership,
•Broadening resource conservation programs that integrate waste prevention and recycling programs
and messages, and
•Providing product stewardship opportunities.

Local Solid Waste Financial Assistance Grants
Ecology also supports waste prevention and recycling programs in King County through the Local Solid Waste
Financial Assistance (formerly known as the Coordinated Prevention Grant) program. Funds are allocated within
the county based on population. The division uses funds allocated to the unincorporated areas to support waste
prevention and recycling efforts such as recycling collection events, yard waste and food scrap recycling, and natural
yard care education and promotion. The cities also receive funds directly from Ecology to support their own waste
prevention and recycling programs (applications are coordinated through the division).
Competitive Grant Program
In 2012, the division worked collaboratively with
the cities to develop a new competitive grant
program to fund innovative projects and services
that further the waste prevention and recycling
goals outlined in this Plan. Cities, commercial
collection companies, and other entities, such
as non-profit organizations or schools, would
be eligible to apply for the grant program. The
program has not been approved by the cities
or funded through the solid waste rate, but the
division will continue to work with the cities
to identify opportunities to initiate the new
competitive grant program in the future.
In the meantime, the division has initially funded
a small competitive grant program through the
Solid Waste Division budget with the focus on commercial food waste. A program funded through the solid waste rate
would extend reach and impact. Descriptions of the funded projects can be found online at:
your.kingcounty.gov/solidwaste/garbage-recycling/commercial-grants.asp
Sustainable Purchasing
King County is also working to reduce the impacts of its operations by purchasing products that have recycled
content and are more resource-efficient and durable. The Sustainable Purchasing Program provides county personnel
with information and technical assistance to help them identify, evaluate, and purchase economical and effective
sustainable products and services.
The division will continue to provide technical assistance to cities by sharing contracts, specifications, and
procurement strategies. Many cities in the county have also implemented environmentally preferable
purchasing programs.
Another strategy to increase sustainable purchasing is to provide training and education about the benefits of
compost applications in parks and landscape projects, topdressing grass in parks, and stormwater
management applications.

Collection
The remainder of this chapter looks at the current collection challenges and recommendations for improvement
for three sectors of generators – single-family households, multi-family households, and non-residential customers,
which include businesses, institutions, and government entities. For each sector, the issues may vary and present
different challenges due to collection methods and the regulations by which they are governed. Construction and
demolition debris is discussed separately at the end of this chapter because of the unique nature of collecting and
processing these materials.
Residential Collection
The residential garbage collection system in King County is a well-established system that serves the region in a safe,
efficient, and cost-effective manner. With the shift toward increased collection services for recyclables and organics,
customers can choose to subscribe to smaller, less expensive collection cans for their garbage. Container sizes now
range from the micro-can at 10 gallons to the mini-can at 20 gallons and on up to the large 90+ gallon cart. The
reduced fee for the smaller cans creates an incentive to generate less waste and divert as much material as possible to
the recyclables or organics carts.
Throughout King County, individual city contracts for collection of garbage, recyclables, and organics differ in a
number of aspects. Cities have entered into contracts with the collection companies at different times and then
renewed contracts as they have expired. Each time a contract is negotiated and renewed, the city may make
adjustments to their services such as changing the range of materials being collected, the collection frequency,
container types or sizes, fee structures, and more. Changes to services may also be negotiated for existing contracts.
The varying collection standards among cities that have resulted from these changes over time have led to
inconsistencies in regional education and messaging, confusion among customers, and difficulties in measuring and
potentially attaining region wide goals.
To illustrate the varying collection standards that currently exist, Table 4-4 presents a summary of single-family
collection services by city and unincorporated area, showing the types of contracts held, the collection company
serving the jurisdiction, container sizes
offered, collection frequency, and fee
structures. The recycling rates for each
jurisdiction and unincorporated area, with
and without organic materials, are also
presented for comparison. The UTC cost
assessment in Appendix A (Section 3.3)
provides additional information about the
UTC-regulated and contracted companies.
Working with the community and the
hauler, the division is exploring the inclusion
of Vashon/Maury Island in the service level
standards, as well as other ways to improve
recycling services provided curbside and
at the transfer station. Skykomish and
Snoqualmie Pass will not be included in the
service level standards at this time because
of their remote locations and low population densities.

Fluorescent tubes are collected at the Factoria Recycling and Transfer Station
As shown in Table 4-4, the single-family recycling rate varies significantly among the cities and unincorporated areas,
ranging from 37 to 65 percent (combining organics and the curbside recyclables) with an average of 55 percent. While
it would be difficult to identify a single factor or factors that will ensure a higher recycling rate, there are some factors
that appear to lead to increased participation and amounts of waste diverted from disposal, as discussed in the
following sections.
Range of Materials Collected
In addition to the materials identified for curbside collection in the last Comprehensive Solid Waste Management
Plan – newspaper, mixed paper, and cardboard; tin and aluminum cans; plastic bottles; glass bottles and jars; and
yard waste – new materials have been added over time. These materials include food scraps and food soiled paper,
aerosol cans, small scrap metal, plastic jugs and tubs, plastic plant pots, plastic trays and clamshells, drink/coffee cups,
and aseptic cartons/containers (such as juice boxes). Some cities have added other materials for collection, such as
electronics, fluorescent bulbs and tubes, and motor oil.
Curbside collection, however, is not necessarily the most efficient and cost-effective way to capture every type of
recyclable or reusable product. Some products cause problems for materials recovery facilities because of their size
or composition, while others are better candidates for take-back programs by manufacturers and retailers to extract
potentially harmful components and recycle other components. Examples of these types of materials and their
particular challenges include the following:
•Plastic bags and plastic wrap are prevalent in the waste stream, particularly residential. Collection of plastic
bags in the recyclables cart creates a nuisance further down the line at the material recovery facilities. As the
bags move through the facility they sometimes catch in and jam the sorting machinery, and they can blow
around and cause litter problems. For these reasons, curbside collection may not be the best option for plastic
bags and wrap at this time. More appropriate options for consideration may be an increased use of reusable
shopping bags and the establishment or expansion of take-back programs at the retail level. For instance, the
Wrap Recycling Action Program (WRAP), a national initiative, provides a network of drop-off locations for clean
and dry plastic film, including wraps, bags and flexible packaging, to be recycled.
•Electronic Products and Fluorescent Bulbs and Tubes Collecting these materials at the curb is complicated
by the fact that some of them
tend to break easily and
contain potentially hazardous
materials that must be safely
disposed. In Washington
State, legislation requires
manufacturers of computers,
monitors, and televisions to
provide separate locations for
free recycling of these items.
Handling electronics through
product stewardship ensures
that the various components,
such as glass, plastic, and
metals, are separated and
recycled as appropriate
and that any potentially
Updated April 17, 2019
Att A Page 106
Ordinance 18893
4-252019 Comprehensive Solid Waste Management Plan - July 2018
hazardous materials are recycled or disposed in a safe and environmentally sound manner. Product stewardship
efforts reduce costs to local governments and their ratepayers by eliminating the costs to recycle these products.
Take-back programs have also been implemented for fluorescent bulbs and tubes. Cities such as Kent and
Shoreline and have contracted with their recycling collection companies to develop a safe, convenient program
for collecting fluorescent bulbs and tubes at the curb. The City of Bothell’s garbage and recycling collection
contract includes curbside collection of electronic products and fluorescent bulbs and tubes as well as collection
at the The Recology Bothell store.
Some cities offer collection of small appliances and home electronics not covered by Washington’s current
product stewardship laws. For appropriately sized products that do not contain hazardous materials, curbside
collection is a viable and efficient option.
•Polystyrene Foam – One type of plastic that is not recommended for residential curbside collection is expanded
polystyrene foam, commonly known as Styrofoam, which includes clamshell containers for take-out foods and
blocks of plastic that are used to package many electronics and other goods. These materials are light and bulky,
can break easily into small pieces, readily mix with other materials causing contamination, and are difficult to
separate out at the material recovery facilities. In addition, the quantity collected is so small that it takes a long
time to collect enough of the material to ship to market. Although there are challenges to collecting expanded
polystyrene foam packaging curbside, the City of Des Moines began offering its single-family residents this
service in 2012. Block expanded polystyrene foam (not packing peanuts) is accepted and residents are asked
to put the blocks in a clearly labeled plastic bag and place it next to their curbside recycling cart. This allows
the expanded polystyrene foam blocks to be handled separately from the commingled recyclables. The
cities of Issaquah and Seattle have taken another approach and banned the use of expanded polystyrene
foam containers for take-out foods. Other cities, such as Kirkland and Redmond, have regular or semi-regular
collection events to collect expanded polystyrene packaging.
Size of Collection Container
The size of the recycling collection cart can affect recycling success. Areas where most residential customers use
smaller recycling carts have reported lower recycling rates and when larger carts have been provided the recycling
rate has increased. As more materials are identified for commingled recycling, and food scraps are added to the yard
waste cart, recyclables carts are getting larger and the size of garbage can to which customers subscribe should
become smaller.
Frequency of Collection
Adjustments to the frequency of curbside collection for garbage, recyclables, and organics can also be used to
influence recycling and disposal behaviors and reduce collection costs and truck traffic. Garbage collection across
King County typically occurs on a weekly basis. This collection schedule has been driven, in part, by the presence
of food scraps and other organics in the garbage that rapidly decompose and have the potential to lead to
environmental or public health concerns. With separate collection of organics for recycling, there is an opportunity to
modify weekly garbage collection to benefit ratepayers and to create a more environmentally sustainable system.
One of the most important factors in determining the appropriate collection frequency for the various material
streams, particularly for organics (yard waste and food scraps), is compliance with the public health and
environmental standards in Title 10 of the Code of the King County Board of Health. To study the effects of changing
the collection method and possibly the frequency of collection, in summer 2007 the division conducted a pilot
Updated April 17, 2019
Att A Page 107
Ordinance 18893
4-26 2019 Comprehensive Solid Waste Management Plan - July 2018
Regulatory Changes Allow Adjustments in Collection Frequency Schedules
After successful completion of the Renton pilot study, a variance to Title 10 of the Code of the King
County Board of Health was approved to allow every-other-week collection of organics (with the yard
waste) for single- and multi-family residents, as well as every-other-week collection of residential
garbage. The variance applies as long as the following standards (excerpted directly from the
variance) are met. During the next review of the Title 10 Health Code, these variances are scheduled
to be adopted.
Residential (Single-Family) Garbage Collection
Residential garbage may be collected every other week provided that:
• Garbage is contained in a provided cart.
• A food scrap collection program is available and actively promoted to residents.
• The garbage collection and food scrap collection services are offered on alternating weeks
to ensure that customers have access to at least weekly disposal or composting options for
problematic compostables.
• Residents are instructed to bag all garbage before placing it in carts to reduce vectors, free
liquids, and litter.
Residential (Single- and Multi-family) Organics Collection (with yard waste)
• When mixed with yard debris, residential food scraps may include all vegetative, meat, dairy
products, pastas, breads, and soiled paper materials used for food preparation or handling;
provided that all collected materials are picked up by haulers which deliver the mixed yard
waste to a permitted transfer and/or permitted composting facility for serviced customers.
• Combined food scraps and yard debris shall be collected no less frequently than every-other-
week, year-round provided that there are no leachate generation, odor, or vector problems.
• Combined food scraps and yard debris shall be collected in carts. Residents shall be instructed
to place food scraps only in the cart provided to them. Any extra customer-provided cans or
large paper bags shall contain only yard debris.
• Compostable bags may be used to consolidate food scraps placed in carts if and only if the bags
have been approved by the facility receiving the material for composting. Plastic bags shall not
be used for yard/food debris.
• Haulers shall make available a cart-cleaning or replacement service for customers with carts
which have unacceptable residue or odor levels to avoid improper disposal of rinse water to
storm drains, yards, etc., and reduce the need for customers to self-clean their containers.
• Educational and promotional materials from the county, city, and haulers shall inform residents
about the benefits of recycling food scraps and soiled paper; and appropriate options for
managing it, including the use of approved compostable bags; and appropriate options and
restrictions for cleaning carts.

study in cooperation with the City of Renton, Waste Management (the collection company), and Public Health. The
purpose of the study was to explore the public health and environmental impacts, customer responses, and effects
on potential waste diversion that would result from changes in collection. In particular Public Health was concerned
about the feasibility of collecting meat and bones every other week in the yard waste cart and changing garbage
collection to less than weekly. To explore these concerns, approximately 1,500 Renton households participated in the
six-month pilot study to look at two different collection schedules:
• Every-other-week collection of all three solid waste streams – garbage, recyclables, and organics, and
• Every-other-week collection of garbage and recyclables and weekly collection of organics.
The pilot study showed positive results for both collection schedules tested. There were no negative health or
environmental impacts observed, and customers were highly satisfied with the collection schedules and the container
sizes provided to adjust for the shift in schedule. Study results indicated not only a 20 percent decrease in the amount
of garbage disposed, but an overall reduction in the generation of garbage, recycling, and organics. An added benefit
was the reduction in truck traffic and transportation costs with the less frequent collection cycles.
As a result, the City of Renton rolled out a citywide program in January 2009 to offer every-other-week collection of
garbage and commingled recyclables, with every week collection of organics.
Renton is the first city in King County to provide every-other-week garbage collection as the standard collection
service for single family households. By 2013, Renton's disposal per household had dropped by 23 percent. While
other factors such as the economic downturn likely played a role in disposal reductions, data from all of King County
over the same time period estimated a disposal drop of 8 percent, suggesting that every-other-week garbage is a
significant tool to reduce disposal and increase recycling.
Commercial/Multi-family Food Scraps Collection (without yard waste)
• Food scraps shall be collected in leak-proof, contractor-provided containers with tightly-
fitting lids.
• Containers shall be kept clean through the use of contractor-cleaning, compostable bagging,
compostable cart lining or boxing, or limiting the types of materials collected from a particular
customer.
• Containers shall be cleaned by the customer or the hauler immediately upon the request of City,
County, or Public Health personnel.
• Customers shall be informed of container cleaning restrictions (i.e., proper disposal of rinse
water and any residues from containers outside of storm drains, landscaping, etc.).
• Customers shall be informed of what is not acceptable in containers and the need to keep
container lids closed when not in use and inaccessible overnight.
• Collection of commercial/multi-family food scraps shall occur weekly at a minimum. Any
exception to the minimum weekly schedule will have to be justified by information on a
particular customer’s food scrap composition, where it can be shown that less frequent
collection can occur without leachate generation, odor, and vector problems.

Fee Structure
Curbside Recycling Services: In nearly all areas of King County, households paying for garbage collection services
also cover the embedded cost of recycling collection services. In most cases, unlimited amounts of recyclables can be
set out. In contrast, the fee for garbage service varies depending on the number or size of containers each household
sets out. A variation of this pay-as-you-throw system is to couple it with a linear rate structure in which there is no
“bulk discount” for having a larger container and the price per gallon is the same across all service levels.
Consequently, King County residents have a clear financial incentive to reduce the amount they dispose and increase
the amount they recycle.
Curbside Organics Services: Sixteen cities, comprising about 55 percent of the population in the county, have
adopted rate structures that embed the cost of organics collection in the curbside garbage collection fee, providing a
further incentive for residents to reduce disposal and maximize use of the recycling options for which they are paying.
In 2016, the average pounds of garbage disposed per household in these cities was 12 percent lower than the average
for the rest of King County.
Curbside Collection of Bulky Items for Residents
An ongoing issue with collection is finding the most efficient and cost-effective way to handle bulky waste – larger,
individual items that do not fit in a garbage can or recycling cart. This type of waste includes recyclable items such as
appliances, potentially reusable items such as furniture, and other large items that must be disposed.
Bulky waste collection services are available
from collection companies throughout the
county; however, these services are not widely
used. Residents may not use the service because
it is expensive, ranging from $25 to $128 per
item, with the possibility of additional charges
for travel time and labor. Customers may also
be unaware of the collection options available
to them. The primary alternatives to bulky
curbside collection are self-hauling the materials
to transfer stations for disposal or recycling, or
taking them to collection events sponsored by
the county or the cities. Neither of these self-
haul options is an efficient way of handling the
materials because of the number of vehicle trips,
the increased number of transactions at transfer
stations, and the high cost of staging
collection events.
The current recommendation is to work with collection companies and the UTC to explore options to increase
the efficiency and reduce the price of curbside collection of bulky items. For example, the cost would be lower if a
small charge were included in the regular garbage fee, and curbside collection days were regularly scheduled and
promoted, thereby increasing the efficiency of the collection routes. Collection systems for bulky items should be
designed, to the extent possible, to divert reusable items to charitable organizations for resale, reuse community
organizations (Green Bee or Buy Nothing community groups), and recyclable items to processing facilities.

Single-Family Residential Minimum Collection Standards
Single-family collection services for garbage, recyclables, and organics are well established. As discussed earlier,
however, there are many variations among the cities in the specific methods of collection and rate structures. The
division has evaluated the factors that appear to lead to higher recycling rates and an increase in the diversion of
materials from the garbage. Based on this evaluation, it is recommended that minimum collection standards be
adopted by the cities and unincorporated areas to provide the optimal service level for reducing waste and increasing
the diversion of recyclables and organics from disposal.
Working with the community and the
hauler, the division is exploring the
inclusion of Vashon/Maury Island in
the service level standards, as well as
other ways to improve recycling services
provided curbside and at the Vashon
Recycling and Transfer Station. Skykomish
and Snoqualmie Pass will not be included
in the service level standards at this time
because of their remote locations and low
population densities.
The minimum collection standards can be
implemented as the county updates its
service-level ordinance and jurisdictions
amend their collection contracts (some of
these targeted standards may not require
changes to contracts or the county’s
service-level ordinance). A description of
the recommended collection standards follows in Table 4-5.
Continuing education and promotion will also be important for increasing recycling and reducing wastes generated
by single-family residents. The cities and the county will increase education and promotion to encourage the
recycling of food scraps and food-soiled paper. In concert with the commercial collection companies, the cities and
the county will also continue to focus promotions on the proper recycling of the standard curbside materials to
increase participation and reduce contamination in the recycling containers. Financial incentives will also be explored
through the fee structure for garbage and recyclables and grants to cities.

Multi-Family Residential Collection
Multi-family recycling has not been as successful as single-family recycling. There are a number of contributing
factors, including space constraints for collection containers and a higher turnover of residents and property
managers. These factors make it difficult to implement standardized collection services and provide consistent
recycling messaging to this diverse sector. Some local progress has been made, however, in developing consistent
design standards to accommodate waste in multi-family complexes. In addition, in many areas of the county there is a
trend in the construction of mixed-use buildings, which contain retail shops on the lower level and residential
units above.
Updated April 17, 2019
Att A Page 112
Ordinance 18893
4-312019 Comprehensive Solid Waste Management Plan - July 2018
Mixed-use buildings present somewhat similar challenges for recycling, including:
• A lack of space for adequate garbage, recycling, and organics collection (often competing with parking needs
and other uses),
• A need for collaborative planning among property developers, garbage and recycling collection companies, and
cities early in the development process to ensure that adequate space is designated for garbage, recycling, and
organics containers in the building design, and
• Different customer types, both residents and employees, with different recycling needs.
Recycling could be increased substantially at multi-family complexes and mixed-use buildings by adopting minimum
collection standards for multi-family collection. The multi-family standards vary somewhat from the single-family
standards to account for differences in service structure. To improve recycling at mixed-use buildings, the cities and
the county must consider both the multi-family collection standards and the recommendations for non-residential
collection. A description of the recommended collection standards follows in Table 4-6.

Increased education and promotion are needed to improve recycling at multi-family complexes. It will require
concerted efforts on the part of many to standardize the collection infrastructure and provide ongoing education and
promotion for property managers and residents alike.
To further increase recycling in multi-family
and mixed use buildings, the division,
in cooperation with other jurisdictions,
property managers, and owners of multi-
family properties, collection companies and
other stakeholders, has conducted several
research and pilot studies (KCSWD 2014b
and 2016b). The findings from these studies
conclude that successful recycling
depends on:
• Collection logistics: Effective
programs place recycling containers
for convenience, access, and ease
of use; provide sufficient space and
capacity for collection both inside and
outside of the buildings; provide tools
for collection, storage, and transport
of recyclables and organics from units
to collection points; and clearly label
collection containers.
• Policies and regulations: Clear policies ensure that recycling is available and addresses issues such as
contamination. Examples might be service level ordinances, city contracts that embed recycling in garbage
rates, and building code requirements.
• Education and outreach: Effective recycling and food waste collection in multi-family buildings hinges on
education and outreach. Strategies such as door-to-door outreach, property manager trainings, and onsite
assistance have been successful. In addition, education and outreach that addresses non-English speaking
communities is crucial.
Improving multi-family recycling will likely require, at a minimum, the following actions:
• Clarify and strengthen building code requirements – The division’s GreenTools program has been working
collaboratively with cities to develop standards that can be used for multi-family buildings. If adopted, these
standards will help ensure that enough space is designed to allow for recycling in future construction.
• Research collection and demographic characteristics, complex by complex – Planning outreach strategies
should begin with a careful look at language and other population demographics, collection infrastructure,
tenant turnover rate, and other applicable characteristics of each complex. Outreach strategies must be
comprehensive and flexible to fit the complex. Customized combinations of outreach tactics and education
reinforcement, designed to address the researched characteristics of that complex, help ensure successful
outreach which will increase recycling and decrease contamination.

•Provide manager and maintenance staff education – Involvement and support from the property manager
and staff is important to the long-term success of multi-family recycling. The institutional knowledge property
managers can provide and the role they play in delivering education to each tenant and at each container are
important considerations. This function should be supported with training and materials.
•Provide ongoing recycling education for residents – Recycling education needs to be provided on a
continuing basis because most multi-family complexes have high tenant turnover. Providing education materials
with the lease and at least annually coupled with information through newsletters and posters ensure that
residents get the message and it is reinforced on a regular basis.
•Involve collection companies to assist with service improvements and education – The collection company
should be involved to provide insight and information about complexes’ recycling infrastructure systems and
to help with education outreach and
feedback to the tenants about the
quality of the recycling and level of
contamination. Companies should
monitor the recycling performance of
the complexes and tag or refuse pickup
of loads that are contaminated.
• Expand organics collection – Currently,
only a few cities are offering collection
of food scraps and food-soiled paper
to multi-family residents. The cities and
the county will need to work with the
collection companies to determine what
containers and collection methods will
work best for multi-family complexes.
Education and promotion will be a critical
component of the new multi-family food
scrap collection programs.
Non-Residential Collection
The non-residential sector comprises a range of businesses, institutions, and government entities from manufacturing
to high-tech and retail to food services. This sector has achieved recycling successes in the last few years, with a
recycling rate of almost 71 percent in 2014, according to Ecology statewide recycling data.
Unlike the residential waste stream, the types of materials discarded by the non-residential sector differ widely
from business to business. Thus, the recycling potential for any particular business or industry can vary greatly. For
example, restaurants and grocers are the largest contributors of food scraps, while manufacturers may generate large
quantities of plastic wrap and other packaging materials.
Because of the diversity of businesses in the region, a more individualized approach is needed to increase recycling
in this sector. One area with significant room for improvement is the diversion of food scraps and food-soiled paper.
The largest increase will be realized as more restaurants and grocers contract with private-sector companies to collect
their food scraps for composting, and more cities begin to offer embedded commercial organics collection.

Updated April 17, 2019

Ordinance 18893
4-34 2019 Comprehensive Solid Waste Management Plan - July 2018
Strategies for increasing recycling in the non-residential sector present some of the same challenges as the multi-
family sector, including:
• The lack of consistent and/or adequate building standards for locating collection containers.
• The need for financial incentives for business owners, property managers, and tenants to take advantage of
recycling services. For example, cities that include recycling services in their garbage rate provide a financial
incentive for businesses to recycle.
• A need for consistent and ongoing technical assistance and education. Involvement and support of the business
owners and property managers is important to the long-term success of recycling at individual businesses or
complexes. Educating building maintenance staff about properly collecting recyclables from building tenants
is important to ensure the proper handling of recyclables. Education for employees about proper recycling
methods is also crucial.
To assess the relative size of the non-residential waste stream in different jurisdictions, the division looked at the
number of jobs located within them. About 94 percent of jobs in the King County service area are located within
incorporated cities. More than 73 percent of these jobs are in cities where the garbage collection contracts include
recyclables collection in the garbage fee. These contracts typically define the capacity required for recycling collection
as 150 to 200 percent of the amount of garbage capacity, and target collection of the same materials as residential
curbside programs.
Non-residential customers have the option to take advantage of recyclables collection offered by their service
provider or to contract with other collection companies that may pay for the more valuable recyclable materials,
such as high-grade office paper. For cities with collection contracts, adding recycling service to their contracts and
including the cost of service in the garbage
rate does lead to higher non- residential
recycling rates and ensure that recycling
services are available to all businesses.
However, while including recycling service
in the rate requires all businesses to pay
for the service, it does not require that
those businesses use the service that the
city contractor provides. Businesses in
unincorporated King County and cities
with UTC-regulated collection services can
choose from a wide array of recycling service
providers in King County for their recycling
needs. Promotion of these services by the
county and these cities will help increase
awareness among businesses of the available
options. For example, the county’s "What do
I do with...?" website (www.kingcounty.gov/
whatdoIdowith) is one place businesses can
look for a service provider.
Another strategy that might increase recycling for some business customers is to consider a rate structure based on
weight or composition of waste, rather than the size of the container. A study was conducted to measure container
weights for non-residential wastes on five weekday collection routes in the City of Kirkland over a 12-month period
(KCSWD et al. 2008a). This study determined that businesses with large amounts of food scraps generate garbage
Food waste comprises a large part of the waste stream at restaurants

that is significantly heavier than the garbage generated by businesses without large amounts of food scraps. In
Washington, non-residential garbage rates are based on the size of the garbage container. So generators of heavy
materials, such as food scraps, pay less than they might if the rates were based on weight, as they are in some
jurisdictions across the country. Because a weight-based rate would likely cost more for generators of large amounts
of food scraps, it would provide an incentive for increased participation in organics recycling programs. Another
strategy is to offer organics collection to businesses at no additional cost or at rates less than garbage.
Construction and Demolition Materials Collection and Recycling
Construction and demolition debris is from the construction, remodeling, repair, or demolition of buildings, other
structures, and roads and accounts for approximately 30 percent of all waste generated in King County. Construction
and demolition debris includes clean wood, painted and treated wood, dimensional lumber, gypsum wallboard,
roofing, siding, structural metal, wire, insulation, packaging materials, and concrete, asphalt, and other aggregates.
The county banned the disposal of large loads of construction and demolition debris at the county-owned transfer
stations and Cedar Hills landfill in 1993. In the following years, until 2016, the division contracted with two private
sector companies to manage the majority of the region’s construction and demolition debris.
Construction and demolition materials are typically hauled from a job site by: 1) the contractor or individual working
at the job site, 2) an independent construction and demolition debris hauler permitted to handle construction and
demolition debris for recycling only, or 3) a collection company permitted to haul materials for both recycling
and disposal.
Construction and demolition debris processing of recyclable materials occurs using either source-separated or
commingled methods. Source-separated processing, which occurs particularly on large projects with adequate
space, involves sorting specific types of construction and demolition material on the job site (e.g., metals, concrete,
and clean wood) and transporting them to one or more recycling facilities. Commingled processing involves placing
all recyclable construction and demolition debris in one container and then transporting the loads to a facility that
uses mechanical and manual methods to sort the recyclable materials. Non-recyclable construction and demolition
waste should be hauled directly to a
construction and demolition debris
transfer station where the waste is
transferred to rail cars for transport to a
landfill.
The division does not accept construction
and demolition waste at its transfer
stations or Cedar Hills landfill, except
for incidental amounts. King County
Ordinance 18166, effective January 2016,
requires that construction and demolition
waste must be taken to a designated
privately-operated construction and
demolition debris recycling and/
or transfer facility. The division has
agreements with the designated facilities
that require these facilities to recycle
readily recyclable materials. These Container with construction and demolition debris for recycling
Updated April 17, 2019

facilities are banned from landfilling certain materials including: clean wood; cardboard; metal; gypsum scrap (new);
and asphalt paving, bricks and concrete. All other construction and demolition waste may be disposed. As markets
develop, the division will consider banning other construction and demolition materials as well.
With improvements in the ability of processing facilities to separate materials, the current trend is toward the
commingling of recyclable construction and demolition debris. If recyclable construction and demolition debris and
garbage are commingled, however, the recyclables are more difficult to extract and the processing facilities end up
having lower facility diversion rates. These mixed loads should therefore be disposed of in their entirety.
Independent construction and demolition debris haulers with commercial permits can transport recyclable
construction and demolition materials from job sites to either source-separated or commingled construction and
demolition debris processors. These independent haulers cannot, however, transport construction and demolition
materials for disposal. Only collection companies permitted by the UTC to haul solid waste can transport construction
and demolition materials for disposal.
The designated facilities listed in Tables 4-7 and 4-8 have agreements with the division and are a part of a network of
designated facilities where construction and demolition materials can be recycled and/or disposed. Figure 2-4, a map
in Chapter 2, shows the locations of these facilties. These facilities agree to meet criteria that the division specifies for
recycling of construction and demolition materials. The division contracts with the King County Sheriff’s department
to provide enforcement that helps to ensure that materials are being recycled. Cities are encouraged to adopt
regulations that complement the King County ordinance. The division’s GreenTools program is available to provide
technical assistance to cities and has a model ordinance for cities to use.

The increased focus on environmental stewardship has reshaped the role of transfer stations in managing solid waste,
creating the need for more robust and modern facilities that will facilitate a sustainable system in the future.
This chapter outlines a transfer system plan that will improve current levels of service, with the flexibility to adapt
to changing needs and emerging technologies. The chapter also discusses plans for effectively managing local and
regional emergencies.
The Transfer System and Services
The concept of a regional transfer and disposal network in King County grew out of a nationwide movement in the
1960s to impose stricter standards for protection of public health and the environment. The original purpose of the
transfer network was to replace the open, unlined community dump sites in use at the time with environmentally safe
transfer facilities where garbage could be delivered by curbside collection trucks and self-haulers. From these transfer
sites garbage could then be consolidated into larger loads for transport to the Cedar Hills Regional Landfill (Cedar
Hills) (see Figure 5-1).
Table 5-1 lists the locations of current transfer facilities, along with the tons of garbage, yard and wood waste received,
numbers of customers served, and recycling services provided for at each facility.

Resource Recovery at Transfer Stations
Resource recovery is separation of recyclables that happens after disposed materials are received by the county. It
is a growing aspect of division business. Historically, the division’s recycling programs have been limited to source
separation by curbside customers. However, since 70 percent of the materials brought to the transfer stations could
be recycled, sorting out target materials can help reach recycling goals. The division is increasing its resource recovery
efforts. Based on a successful pilot project that separated
tons of recyclables at the Shoreline Recycling and
Transfer Station, new staff were approved for expanded
sorting of recyclables from mixed waste at the Shoreline,
Bow Lake, and Enumclaw stations. Recycling bins are also
provided near where self-haul customers unload their
cars at those stations.
In addition to providing the standard recycling services,
Bow Lake, Enumclaw, and Shoreline Recycling and Transfer
Stations have increased the amounts of cardboard, scrap
metal, and clean wood recycled by actively removing
these materials from mixed waste with use of an excavator
and by providing additional staff to engage customers in
the separation of recyclables from mixed waste loads at
the point of disposal.
Services for Moderate Risk Wastes
Many common household products, such as pesticides and certain cleaning products, contain ingredients that are
toxic, flammable, reactive, or corrosive. Disposed improperly, these products, referred to collectively as moderate
risk waste, can pose a threat to human health and the environment. Moderate risk waste generated in King County is
managed through the Local Hazardous Waste Management Program (LHWMP). This program is jointly managed by
Materials Recovery by the Numbers
In 2017, additional staffing, recycling bins, and signage in the self-haul areas resulted in the recovery of
7,184 tons of cardboard, metal, and wood, an increase of 1,323 tons over 2016.

King County, the City of Seattle, the 37 cities within our service area, and Public Health. The guiding policies and plans
are contained in the joint Local Hazardous Waste Management Plan (Watson 2010), mandated under RCW 70.105.
The county accepts moderate risk waste from residents through two avenues: the traveling Wastemobile and the
stationary drop-off site at the Factoria Recycling and Transfer Station. In addition, the City of Seattle operates two
moderate risk waste collection sites within its borders, which are open to all King County residents. Wastes collected
through these services are recycled, reused, or incinerated when necessary. None is disposed at Cedar Hills. Moderate
risk waste collection for residents is funded through a surcharge
on garbage disposal, residential and business garbage collection,
and wastewater discharge fees. Residents and businesses using
the services are not charged at the drop-off locations. Jurisdictions
receive funds from the LHWMP to provide the service.
Created in 1989, the county’s Wastemobile was the first
program of its kind in the nation. It is a mobile service that
travels to communities within King County, staging collection of
moderate risk waste at each site for two or three days at a time.
The traveling Wastemobile had 21 events in 2017 that served
11,851 King County residents, collecting 272 tons of moderate
risk waste. This represents a customer increase of five percent
from 2016. The Wastemobile also provides a mobile moderate
risk waste collection at The Outlet Collection Seattle (formerly
the Supermall) in Auburn each Saturday and Sunday. In 2017,
235 tons of moderate risk waste were collected at this location
from 9,481 customers, six percent more customers than used
the service in 2016. The county’s Factoria Recycling and Transfer
Station offers moderate risk waste drop-off service six days a
week. In September 2017, the new Factoria state-of-the-art
moderate risk waste facility opened. It has more capacity and
functionality than the previous facility did, enabling the division
to effectively and safely collect hazardous waste. In 2017, a little
over 13,000 customers brought 281 tons of moderate risk waste to Factoria.
Since 2008, Factoria and the Wastemobile have also accepted moderate risk waste from small businesses. In 2017, this
program served 267 small-quantity generator business customers and collected 18 tons of moderate risk waste.
Collection of Sharps
Sharps are medical products, such as hypodermic needles, scalpel blades, and lancets, which require special handling
to ensure their safe collection, transfer, and disposal. Without proper containment, sharps can pose a safety hazard to
workers through potential exposure to blood-borne pathogens or other disease-causing agents. Within King County,
the disposal of sharps is regulated by Title 10 of the Code of the King County Board of Health and by King County’s
Waste Acceptance Rule PUT 7-1-6(PR), 9/17.
Disposal of sharps in the general waste stream is prohibited. Separate, secure receptacles for sharps collection are
provided for residents and small businesses at the Vashon Recycling and Transfer Station with prior authorization from
the division’s Special Waste Unit. Residents may also deposit home-generated sharps in separate, secure receptacles
at the Factoria, Shoreline and Bow Lake Recycling and Transfer Stations. Business-generated sharps are not accepted

at the transfer facilities, except at Vashon with prior authorization from the Special Waste Unit. Sharps generated by
medical facilities or businesses are accepted for disposal at Cedar Hills with prior authorization from the Special
Waste Unit.
There are alternative methods for the proper management of sharps. For example, some health care providers and
pharmacies will take back used sharps in pre-approved containers. There are also mail-in programs available.
Trends in Transfer Station Usage
Figure 5-2 shows the tons of garbage received at the transfer stations and the landfill over the last 27 years. The
drop in total tons disposed in the early to mid-1990s is attributable to the success of waste prevention and recycling
programs that began in the late 1980s, the withdrawal of the City of Seattle from the county’s system in 1991, and the
ban on most construction and demolition debris from the division’s solid waste system in 1993. In 2004, the amount
of garbage taken directly to Cedar Hills decreased significantly due to an increase in the fee charged to commercial
collection companies that were hauling wastes directly to the landfill. The economic downturn is primarily responsible
for the tonnage reduction since 2007. The division does not expect a rapid return to earlier tonnage levels.
Seventy-two percent of the garbage received at the transfer facilities in 2017 was brought by the larger, commercial
collection trucks, with the remaining 28 percent delivered by business and residential self-haulers (shown in Figure
5-3). While the larger garbage loads come from the commercial haulers, self-haulers account for 87 percent of the
customer transactions (Figure 5-3). At some of the urban stations that are operating at or near maximum capacity,
the mix of self-haul and commercial customers can cause long traffic queues and crowded conditions on the tipping
floor. Transfer station capacity depends on a number of variables such as the mix of collection trucks versus self-
haulers, available tipping stalls for each, on-site queue capacity for each, and trailer loading ability (in the case of the

older stations with no preload compactors). The division has managed these problems, to the extent possible at each
station, by providing separate queuing lanes for the two customer types and allowing maximum separation on the
tipping floor, for safety as well as efficiency. Crowding is somewhat eased by the fact that self-haulers typically use the
stations more on weekends, while commercial transactions occur primarily on week days.
To understand who self-hauls to the transfer facilities and why, the division conducts periodic surveys of customers
through on-site questionnaires at each facility. Self-haulers consist of single- and multi-family residents and non-
residential customers, such as landscapers, small contractors, industries, offices, stores, schools, government agencies,
and increasingly, independent haulers for hire. The most common type of self-hauler is the single-family resident.
Of the self-haul trips, about 88 percent are made by residential customers, who bring in about 75 percent of the self-
haul tons. About 12 percent of the trips are made by non-residential self-haulers, bringing about 25 percent of the
self-haul tons.
The number one material disposed by self-haulers is dimensional lumber (a subset of construction and demolition
debris), followed by yard waste, other construction and demolition wastes, furniture, and scrap metal. The division’s
waste characterization studies indicate that approximately 70 percent of the materials disposed by self-haulers
are recyclable.

Planning Capacity at New Recycling and Transfer Stations
New recycling and transfer facilities are being designed to safely and efficiently serve both commercial
and self-haul customers. When a new station is designed, maximum capacity is not targeted to occur
when the station opens, but is dependent upon vehicular projections into the future, usually 20 - 30
years. The mix of traffic and tonnage on weekends and weekdays varies significantly, so it is usually
vehicular capacity on weekends that drive queue length, number of tip stalls, and therefore overall size
of the facility. On weekdays, tonnage drives the operation of a station.

Waste characterization studies conducted at transfer stations also survey self-haulers on-site at the transfer facilities
(Cascadia 2016). The most common reason for transfer station visits was “large amount of garbage”(18 percent).
Other primary reasons for self-hauling included, “items too big to fit in garbage can,” (16 percent) “cheaper or saves
money”(14 percent), “other”(10 percent), and “cleaning home or workplace”(nine percent). The most frequent
response from nonresidential customers was “large amount of garbage” (26 percent).
Evaluation and Planning for the Urban Transfer Stations
The county’s implementation of the Solid Waste Transfer and Waste Management Plan (Transfer Plan) is underway to
renovate the aging transfer system to better serve its customers. This investment in the transfer system will help the
division meet demands created by the growth in population since Cedar Hills began accepting waste in the mid-
1960’s, by technological changes in the industry, and by ongoing
advances in the recycling and salvage of materials from the
waste stream.
The Planning Process
Since 1992, continuing growth in the county and technological
changes in the industry have intensified the need for significant
improvements and updates to the division’s infrastructure. The
2001 Comprehensive Solid Waste Management Plan (2001 Plan)
reasserted the need for an updated transfer system (KCSWD
2002). Given the scope of changes anticipated, both the cities
and the county recognized the need for a more coordinated
approach to the planning and decision-making process. In 2004,
the County Council adopted Ordinance 14971, which prioritized
evaluation of the urban transfer station network as an integral
part of the waste management plan and established a process for
collaborative participation by the cities in solid waste planning.
Codified in KCC 10.25.110, Ordinance 14971 outlined an iterative
process of analysis and reporting that would culminate in a
plan containing recommendations for upgrading the solid
waste system. The ordinance also established a forum for cities,
division, and County Council staff to collaborate on solid waste
planning through the advisory committees – the Solid Waste
Advisory Committee (SWAC) and the Metropolitan Solid Waste
Management Advisory Committee (MSWMAC). The legislation
also created the Interjurisdictional Technical Staff Group (ITSG) to assist MSWMAC with its work. ITSG included staff
representatives from the cities, County Council staff, and the division. The group was very active during the initial
stages of data gathering and analysis for the planning process, but is no longer meeting. Much of the initial work was
to evaluate the whole system and develop recommendations that would help inform and guide the direction of
this Plan.
Along with division staff, the committees first analyzed various aspects of the solid waste system through four iterative
milestone reports. These reports identified the need to renovate the county’s urban transfer facilities by evaluating the

current conditions of each facility, discussed options for public and private ownership and operation of solid waste and
recycling facilities, and identified packaged alternatives for the future configuration of the transfer station network.
These four milestone reports culminated in the Transfer Plan, which provides recommendations for upgrading the
transfer station system and services; methods for extending the lifespan of Cedar Hills; and options for preparing the
landfill for eventual closure. Through the process of analysis and reporting, the division’s stakeholders had a significant
role in shaping the recommendations in the Transfer Plan. At the conclusion of the process, they communicated their
support of the plan to the King County Executive and the County Council.
Before final approval of the Transfer Plan, the County Council requested an independent third-party review of the
Transfer Plan. The review was conducted by the firm Gershman, Brickner & Bratton, Inc., who fully supported the
primary objectives of the plan to modernize the transfer station system and maximize the lifespan of the Cedar Hills
landfill. Based on Gershman, Brickner & Bratton’s review and the support of both SWAC and MSWMAC, the County
Council unanimously approved the Transfer Plan in December 2007.
In 2012, as the division moved to implement the Transfer Plan, several cities raised questions about how changes in
core planning assumptions may call for a change in if/how to proceed with the replacement of the Algona, Factoria,
and Houghton transfer stations. With a lower tonnage forecast than was predicted in 2006 when the Transfer Plan
was agreed to, and the indication that five cities were going to exit the system in 2028 resulting in an additional drop
of system tonnage, it was decided to conduct a Transfer Plan Review, starting in 2013. At the end of that process, it
was confirmed that a new Factoria Recycling and Transfer Station should be built and siting for a new South County
Recycling and Transfer Station should continue. However, siting for a new Northeast Recycling and Transfer Station
was postponed while alternative options were explored.
In 2014, Council Motion 14145 directed the division, in collaboration with stakeholders, to continue to evaluate a
mix of capital facilities and operational approaches to address system needs over time, including implementing
operational approaches such as transaction demand management strategies that would provide service for the
northeast county without building an additional transfer station; and to compare trade-offs and benefits with the
Transfer Plan.
The division transmitted a
final report to the County
Council on June 30, 2015 as
directed by Motion 14145.
The report reaffirmed that
the siting process for the
South County Recycling
and Transfer Station should
continue, but that the siting
process for the Northeast
Recycling and Transfer
Station should be postponed.
Instead, the report
recommended that the
division conduct a demand
management pilot to test
whether instituting longer

hours and peak pricing at the Factoria Transfer Station would influence customers to either use the station at different
hours or to use another station. During lengthy discussions with the division, advisory committees raised numerous
concerns about the demand management pilot, including its impact on service levels, traffic, and regional equity.
In 2017, with the city of Bellevue signing the Amended and Restated Solid Waste Interlocal Agreement (Amended
and Restated ILA), and higher tonnage than was forecast in 2014 coming into the system, the county concluded
that the demand management pilot as planned would likely not be effective. County Council Ordinance 18577 and
accompanying Motion 14968 canceled the demand management pilot and initiated a further planning effort for
transfer capacity in the Northeast service area. The legislation allocated one million dollars to planning work to assess
waste transfer capacity needs in the Northeast area of King County and options to meet these needs. It also directs
the division to plan for needed transfer station capacity in the Northeast area that would be in addition to the existing
Factoria Recycling and Transfer Station. By early 2018, the remaining four cities, Clyde Hill, Hunts Point, Medina and
Yarrow Point, also signed the Amended and Restated ILA.
Service Level Evaluation Criteria
In the first milestone report (KCSWD and ITSG 2004), the division and advisory committees developed 17 criteria to
evaluate the urban transfer facilities. To determine the appropriate standards of performance, the division consulted
the local commercial collection companies and other experts, and applied national environmental and transportation
standards. Details on the application of these evaluation criteria to individual facilities are contained in the second
milestone report prepared by the division and advisory committees and approved by the County Council (KCSWD
2005a). Criteria to address costs and rate-setting considerations were applied during the development of system
alternatives in the final milestone report (KCSWD 2006a).
The evaluation criteria were applied to five of the six urban stations – Algona, Bow Lake, Factoria, Houghton, and
Renton. The former First Northeast station was not evaluated because it was in the process of being rebuilt. The
rebuilt station opened in 2008 as the Shoreline Recycling and Transfer Station. These criteria were again evaluated
and confirmed as appropriate during the 2013/14 Transfer Plan Review process. They provide guidance for evaluating
existing stations and designing new ones, but the facility site and other constraints may mean that new facilities do
not entirely meet all criteria.
For the urban station evaluations, the 17 criteria were grouped into three broad categories – level of service to
customers, station capacity and structural integrity, and effects on surrounding communities. As expected for these
five aging facilities, the majority of the criteria were not met, resulting in decisions to reconstruct or close the stations
when sufficient replacement capacity was available.
The three categories of evaluation criteria are described below:
Level of Service
• Estimated travel time to a facility – This criterion measures how conveniently located the facilities are for
customers, measured by the maximum travel time to the closest facility in their service area. The standard was
established as 30 minutes for at least 90 percent of the customers. It provides an indication of whether the
transfer stations are well dispersed throughout the county.
• Time on site – Time on site measures the time to get in and out of the station, including unloading time. It was
evaluated separately for commercial haulers (with a standard of 16 minutes) and business and residential self-
Updated April 17, 2019

haulers (each with a standard of 30 minutes). It provides an indicator of whether a transfer station can handle
customers efficiently.
•Facility hours – Individual days and hours of operation for each station are based on the division’s usage data and
customer trends. Some of the urban stations are open in the early morning or late evening hours to serve the
commercial haulers. Currently, the only days that the entire system is closed are Thanksgiving, Christmas, and
New Year’s Day.
•Level of Recycling Services – The final criterion in this category was whether recycling services provided at
the stations met the waste prevention and recycling policies established in the 2001 Comprehensive Solid
Waste Management Plan. In general, the policies directed that all stations should 1) provide for collection of
the curbside recyclables, including glass and plastic containers, tin and aluminum cans, mixed waste paper,
newspaper, and cardboard, 2) where feasible, provide areas for source-separated yard waste collection, and 3)
maintain the capacity to add collection of new materials based on market opportunities and community needs.
Station Capacity
Station capacity is likely the single greatest limitation of the five urban transfer stations, both now and in the future. It
was measured using a number of criteria that affect daily operations, future expansion, and emergency capacity.
•Vehicle and tonnage capacity –
Two major operational
considerations measured were
station capacity for vehicle traffic
and solid waste tonnage, both at
the time of the study and over the
20-year planning horizon. Optimal
operating capacity is the maximum
number of vehicles and tonnage
that can be efficiently processed
through the station each hour
based on the station design and
customer mix. To derive criteria that
would indicate how well a station
could be expected to perform, the
division modeled its criteria after
the transportation standards used
to measure roadway capacity. The
transportation standards were modified to assign measures of capacity to transfer facilities. The optimal level
of service was defined as “able to accommodate vehicle and tonnage throughput at all times of the day, except
for occasional peak hour times. Based on the criteria, a station that provides the optimal level of service more
than 95 percent of the time is considered underutilized, meaning it offers more capacity than required for the
area it serves. A level of service in which capacity is exceeded during only 5 to 10 percent of operating hours is
considered optimal.
•Space for three days’ storage – Available storage capacity establishes whether a transfer station can continue to
operate, or accept garbage, for at least three days in the event of a major regional disaster.

•Space for station expansion – Stations were evaluated to determine 1) whether there is space for expansion on
the existing property or 2) whether there is adjacent land available on which to expand operations. These two
standards were used primarily to determine if the station could be expanded in its current location or if a new
location would be needed to efficiently manage current and future needs.
•Meets facility safety goals – While all stations hold current permits from Public Health and meet health and safety
standards, overall safety is a concern as stations become more congested and operations more constricted.
The presence of these physical challenges at the stations does not mean they operate in an unsafe manner; it
does mean that it takes extra effort by staff and management at the stations to ensure the facilities are
operating safely.
•Roof clearance – This criterion measures a station’s capacity to handle the larger commercial collection trucks.
Through discussions with the commercial collection companies, it was determined that a minimum clearance of
25 feet was needed to allow the new, larger trucks to unload efficiently. The longer truck/trailers with automated
lifts, which allow the garbage to
slide out the back of the trailers,
require higher vertical clearance
than trucks did in the past. Before
impovements were made to some
of the older stations, the collection
trucks could hit and potentially
damage station roofs, supporting
structures, or hanging lights as
they unload.
•Ability to compact waste – This
criterion examines whether the
station is equipped with, or has the
space to install, a waste compactor.
Waste compactors increase
efficiency and reduce costs by
compressing more garbage into
fewer loads for transport to the
landfill or other disposal option. When garbage has been compacted, transfer trailers can carry about one-third
more tons per trip, resulting in less traffic, less wear on local roads, less fuel use, and a reduction in greenhouse
gases.
•Structural integrity – The purpose of this criterion is to ensure the facility meets code requirements for seismic,
wind, and snow events. All facilities were constructed in compliance with the applicable standards of the time
and were grandfathered in their current condition and presently meet the “life safety” standard, meaning the
station would not endanger occupants in the event of an emergency. The current standard for assessing new
transfer buildings for seismic performance is the Immediate Occupancy standard, developed by the Federal
Emergency Management Agency (FEMA). This standard means that the facility could be occupied immediately
following a seismic event. Because the King County Emergency Management Plan identifies transfer stations as
critical facilities in the event of an emergency, this FEMA standard applies to all new stations.

One of the division’s highest priorities is to minimize the effects of its facilities on host cities and surrounding
communities. Through its advisory committees and meetings with cities, the division works to understand city and
community issues and concerns and bring their perspectives to system planning. Working together, five criteria were
developed to evaluate effects on communities.
•Meets applicable local noise ordinance levels – This criterion is to ensure that a facility does not violate state or
local (city) standards for acceptable noise levels. State and city standards are based on maximum decibel (dBA)
levels that consider zoning, land use, time of day, and other factors. Evaluations were based on the existence of
any reports of noise violations to the cities and additional noise level measurements performed at each station
by a consultant.
•Meets Puget Sound Clean Air Agency standards for odors – The primary measure of odor issues is complaints by the
public or employees. Complaints are typically reported to the Puget Sound Clean Air Agency (PSCAA) or directly
to the division. Complaints to PSCAA are verified by an inspector. If an odor is verified and considered to be
detrimental, PSCAA issues a citation to the generator of the odor. The division also tracks and investigates odor
complaints.
•Meets goals for traffic on local streets – This criterion measures the impacts on local streets and neighborhoods
from vehicle traffic and queuing near the transfer stations. The area that could be affected by traffic from self-
haulers and commercial collection trucks extends from the station entrance to the surrounding streets. The
division hired a consultant to evaluate this criterion based on two standards: 1) that additional traffic meets
the local traffic level of service standard as defined in the American Association of State Transportation Officials
Manual and 2) that traffic does not extend onto local streets during more than 5 percent of the station’s
operating hours.
•Existence of a 100-foot buffer between the active area and nearest residence – This criterion calls for a 100-foot
buffer between the active area of the station and the nearest residence.
•Compatibility with surrounding land uses – The final criterion used to evaluate the stations was the most
subjective and difficult to apply. It looks at consistency with land use plans and zoning regulations, aesthetics,
and compliance with state and local regulations. This criterion was evaluated for each station during lengthy
discussions between the division and its advisory committees.
Since the level of service criteria were first applied to the transfer stations in 2005, the division has made changes and
upgrades to the system. New recycling and transfer stations have been completed at Bow Lake and Factoria, and the
roofs at Houghton, Algona and Renton were raised to meet the roof clearance standard. In 2017, the division applied
selected criteria to the transfer stations again, using the current system conditions and an updated tonnage forecast.
Table 5-2 presents the updated results for criteria that could be affected by these changes. Although the Shoreline
station was not part of the original analysis, it is included in the update for reference.

Plans for the Urban Transfer Stations
Based on the application of evaluation criteria, the division and its advisory committees developed a plan to
modernize the transfer system, including the addition of waste compactors and other changes needed to provide
efficient and cost-effective services to the region’s customers.
Activities approved by the County Council in the Transfer Plan include the following:
Bow Lake – deconstruct the existing transfer station and construct a new recycling and
transfer station on the existing site and adjacent property - complete,
Factoria – deconstruct the existing transfer station and construct a new recycling and transfer
station on the existing site and adjacent property - complete,
Algona – close the station after it is replaced by a new recycling and transfer station in the
South County area – site selected,
Houghton – close the station when replacement capacity is available at a new Northeast
recycling and transfer station, and
Renton – close the station when replacement capacity is available.
Although approved for closure, this Plan recommends reserving the option to retain the Renton station in some
capacity, should its closure leave Renton and surrounding rural areas underserved. After the new transfer stations
have been completed, the impact of closure can be fully evaluated. Table 5-3 shows the planned changes for the
urban transfer stations and the two areas identified for construction of new stations.
The new Bow Lake Recycling and Transfer Station is located on the site of the old Bow Lake Transfer Station and
on adjacent property purchased from the Washington State Department of Transportation. During construction,
the facility remained open to commercial haulers and self-haulers. The new transfer building opened in July 2012,
immediately followed by deconstruction of the old transfer building to make way for an expanded recyclables
collection area and new scale house. The station was completed in 2013.
The new Factoria Recycling and Transfer Station was built on the existing site and adjacent property purchased
by the division for construction of the new facility. The old station remained open as the new transfer building
was constructed. Once the new building was complete, the old building was deconstructed to make room for the
stationary moderate risk waste facility and recyclables collection area. The new facility was completed in late 2017,
cost approximately 90 million dollars, and will not be expanded on the upper Eastgate Way property near the Factoria
Recycling and Transfer Station per Ordinance 18577 and accompanying Motion 14968.
A new South County station, estimated to cost about 113 million dollars, will replace the current facility in Algona
on a site just north of the existing station. A new Northeast Recycling and Transfer Station is recommended, with an
estimated cost of approximately 133 million in 2017 dollars. Initial planning for Northeast area transfer capacity is
underway with more substantive work toward a new Northeast Recycling and Transfer Station anticipated after Plan
approval in 2019.
All new stations will be built to similar standards of service and sustainability as the Bow Lake, Factoria, and Shoreline
Recycling and Transfer Stations. There will be differences to accommodate community needs (e.g., Factoria retained
a stationary moderate risk waste facility), and each station will be appropriately sized and designed to meet tonnage
and customer requirements. All stations will have improved capacity, waste compactors, and additional space for
collection of recyclable materials. The capacity to accept yard waste and other recyclables from commercial collection
companies and to sort and remove recyclables from mixed loads will also be considered for new transfer facilities.
For each new station, the division will seek the highest appropriate environmental certification as mandated by the
County Green Building Ordinance.

Transfer Facility Siting
As described earlier in this chapter, the need for new transfer facilities was identified through a comprehensive
analysis of the transfer system network, with extensive involvement from the division’s advisory committees. While
general areas for site locations were identified (Figure 5-4), specific sites or specific site selection criteria were not.
The siting of a transfer facility is based on the technical requirements of operations and site constraints, such as site
size and shape; however, a successful siting effort must also be tailored to address the needs and concerns of the
service area communities. Many of the already renovated stations were rebuilt on the same site that the old station
was built on in part due to the challenges finding a suitable site in the urban area. The siting process involves a
number of steps – from development of site selection criteria to final selection of a site – and public involvement plays
an important role each step of the way. The following section describes how the division implemented the standards
and practices developed for transfer station siting during the planning process in its search for a new south county
facility site. A similar process adapted to the needs of Northeast area communities will be used to site a new northeast
county facility.
Siting a New South County Recycling and Transfer Station
The search for a site to replace the Algona Transfer Station with a new South County Recycling and Transfer Station
began in 2012. The new station will serve the same communities that are served by the current Algona station –
Algona, Auburn, Federal Way, and Pacific.
A Siting Advisory Committee (SAC) was formed to advise the division from a community and system-user perspective
by identifying community concerns and impacts, developing criteria used to evaluate potential sites, and expressing
opinions and preferences. SAC members included representatives from cities, local agencies and businesses,
chambers of commerce, school districts, commercial garbage and recycling collection companies, transfer station
users, environmental and neighborhood groups, tribes, and interested citizens.

5-192019 Comprehensive Solid Waste Management Plan - July 2018
In addition to forming a SAC, the division worked to ensure that members of the communities to be served by the
new station were aware of the project, were able to receive information about the project, and had opportunities to
give input on the project. Public information efforts to non-English speaking communities included translating public
information materials into Spanish, Russian, and Korean and providing translators at public meetings. In addition, the
division conducted an initial Equity Impact Review (see text box for more information) to provide more information
about the communities surrounding the potential sites.
After an extensive site selection process and the completion of an Environmental Impact Statement (EIS), the County
selected a site at 35101 West Valley Highway South, Algona, WA which is just north of the existing station. As indicated
in Table 5-3, the next phase of this project, design and permitting, will be undertaken in the next two years, followed
by another two years of construction. It is anticipated that the existing Algona Transfer Station will continue to
operate until the new station is complete. At that point, the old station will close. Up-to-date information about the
South County Recycling and Transfer Station project can be found on the division’s website: www.kingcounty.gov/
depts/dnrp/solid-waste/facilities/algona.aspx.
Providing Transfer Capacity in the Northeast Service Area
As early as the 1992 Comprehensive Solid Waste Management Plan, the Houghton Transfer Station was identified as
being in need of replacement. Throughout the years, subsequent evaluations and studies, including the Transfer Plan,
confirmed the need for a new station and the closure of the old one. The existing Houghton station was constructed
in the mid-1960s on 8.4 acres of land. The station is bordered by the closed Houghton landfill on the north side, Bridle
Trails State Park on the south side, and private homes on the east and west sides. The station has an open-sided,
direct-dump style transfer building, a scalehouse, a modestly-sized no-fee recyclables collection area for a limited
range of materials, and trailer parking areas.
A New Northeast Recycling and Transfer Station is Recommended
Although previous plans recommended a new station, a Northeast station decision was not finalized, offering the
opportunity to re-evaluate transfer needs as part of this plan. County Ordinance 18577 directed that this plan “…
must address current waste transfer needs in the Northeast area of King County and how those needs are proposed
to be met.” The Public Review Draft Plan issued in January 2018 identified three options to meet Northeast area
The Equity Impact Review
The Equity and Social Justice Strategic Plan 2016-2022 (King County 2016b) establishes a goal to “Develop
facility and system improvements responsive to the values and priorities of residents and stakeholders
and achieve pro-equity outcomes.” The purpose of the Equity Impact Review is to fulfill that goal and to
ensure that equity impacts are considered during the siting, design, and operation of a new facility. It
is a process to identify, evaluate, and communicate the potential impacts on equity – both positive and
negative – of the project. There are five phases of the Equity Impact Review which correspond to the
different stages of the project. For instance, an initial Equity Impact Review was conducted during the
siting of the South County Recycling and Transfer Station. The review determined the populations that
would likely be impacted by the project and what the impacts might be. An expanded Equity Impact
Review that will address approaches that will best meet community priorities and concerns will be an
integral part of the design and operation of the facility.

transfer needs: 1) Houghton station “as is,” 2) site and build a new Northeast recycling and transfer station, and 3) a
combination of existing and/or new facilities.
After public comment and careful consideration of the three options, the option to site and build a new Northeast
recycling and transfer station is recommended, with the Houghton station to be closed after the new station is
complete. The location, services offered, and financial and transportation impacts to the community are components
of providing regional equity in transfer services in the Northeast service area. A new station will provide similar
services in the Northeast service area that updated transfer stations in other urban service areas now provide. The
Northeast area is among the fastest growing parts of the county and was the third busiest station in terms of both tons
and transactions in 2017. A new station will meet key levels of service to accommodate current and future tons and
vehicles, both on a daily basis and when emergencies require extra storage. It would include compaction which could
decrease truck traffic from the station to the landfill by almost a third. It would be designed to move customers through
the station efficiently, reducing customer disposal time. It also would allow for full service recycling to help meet
county goals. A new station is the highest cost option, but its costs are in line with the cost of modern stations recently
built in other parts of the urban area. Siting a new station could take time and generate host community opposition.
Initial planning for Northeast area transfer capacity is underway with more substantive work toward a new Northeast
Recycling and Transfer Station anticipated after Plan approval in 2019. The division will use experience gained in siting
the South County Recycling and Transfer Station to refine its approach to understanding capacity needs, evaluating
potential sites, and involving the community. Criteria for any facility that might ultimately be built in the Northeast
service area would be developed with members of that community. A first step in this process will be a dialogue to
understand the needs and concerns of all of the stakeholders in the northeast service area.
Other Northeast Capacity Options Considered
The Houghton station “as is” and a combination of facilities, described below, were considered as options in the Public
Review Draft Comp Plan, but are not recommended as the best way to provide transfer capacity in the Northeast
service area.
Keep Existing Houghton Station Open
This option would keep the existing station open indefinitely and largely in its current condition. This option is the
“no action” or status quo alternative to addressing transfer capacity in the Northeast service area. It would be the
least expensive option but would continue to provide lower levels of service for the Northeast compared to other
urban parts of the County system. Recycling options would be limited, compaction to reduce truck traffic would
not be available, and there would not be enough space to efficiently accommodate the future tons and numbers
of customers. Host city concerns about continued operation of the open sided station adjacent to a residential
neighborhood would continue.
Combination of Facilities
This option would use a combination of facilities to meet transfer capacity needs based on expected population
and employment growth, transportation corridors and other criteria to determine the types and sizes of transfer
stations needed to serve the area. It would consider various combinations of facilities to meet transfer capacity
needs. For example, one combination that was used to develop the comparison in Table 5-4 would be to leave the
existing Houghton Transfer Station open to serve only self-haulers and site and build a separate facility elsewhere in
the service area to serve commercial haulers. Although this option could meet more level of service targets than the
Houghton station alone, it carries some of the challenges of both the Houghton “as is” option (continued open sided
station, limited space) and the new NE station option (siting a new facility, potential host community opposition).

Evaluation and Planning for the Rural Transfer Facilities
Historically, the rural areas were served by small
community landfills. As those landfills closed,
most were replaced by either a transfer station or
a drop box. The Duvall and Hobart (near Maple
Valley) landfills were closed without replacement.
Currently, rural King County is served by two
recycling and transfer stations, in Enumclaw and
on Vashon Island; and two drop boxes, in North
Bend (Cedar Falls) and Skykomish.
The Vashon Recycling and Transfer Station
Updated April 17, 2019
Att A Page 145
Ordinance 18893
5-22 2019 Comprehensive Solid Waste Management Plan - July 2018
In 2007, the division applied the same 17 criteria used for the urban stations to the rural facilities. Because the drop
boxes are essentially collection containers covered by roof structures, there is no building per se to evaluate, so many
of the criteria did not apply. Criteria specific to the rural system were not developed because a preliminary look
indicated that the rural facilities, for the most part, met the standards set for the urban system, although they may
be open for fewer hours and days. To provide an appropriate level of service to area residents and the commercial
collectors, the division periodically reviews the operating hours of rural facilities and makes adjustments as needed.
The Enumclaw Recycling and Transfer Station, which opened in 1993, serves the City of Enumclaw and southeastern
King County. The City of Enumclaw provides its own garbage collection service and takes the wastes to the transfer
station. The station offers a wide variety of recycling opportunities and is equipped with a waste compactor. This
station met all of the evaluation criteria, with the capacity to provide a wide range of services and the flexibility to
respond to future needs.
The Vashon Recycling and Transfer Station opened in 1999 to serve residents and businesses on Vashon Island. This
station also met all of the evaluation criteria. It accepts a wide range of recyclables and is also equipped with a waste
compactor. Because of its remote island location, the facility accepts some construction and demolition materials
and special wastes for disposal that the other stations do not. The division partnered with Zero Waste Vashon, a
community group focused on finding practical ways to recycle waste, to conduct a pilot program to collect yard
waste mixed with food waste. The program started in October 2015 and was made permanent in 2016. The division
will continue to partner with Zero Waste Vashon to find solutions to managing Island waste in a cost effective and
environmentally appropriate fashion.
The drop boxes are scaled-down facilities, designed to provide cost-effective, convenient drop-off services in the
more remote areas of the county. The Cedar Falls Drop Box, which opened in 1990, serves self-haulers in the North
Bend area. It has three containers – two for garbage and one for yard waste – and provides a collection area for
some recyclables. This facility met all applicable evaluation criteria except for vehicle capacity, which is primarily
due to heavy weekend use. Currently, the same scale is used by both inbound and outbound traffic, which can lead
to backups on weekends when the station is most busy. The division is considering a number of improvements to
this facility, including a second scale to address heavy weekend use, another container for garbage or yard waste
collection, and expanded recycling opportunities.
The most remote facility operated by
the division is a drop box in the Town of
Skykomish. Built in 1980, the drop box
serves Skykomish and the communities of
Grotto and Baring. Skykomish provides its
own garbage collection service and takes
the wastes to the Skykomish Drop Box. The
drop box is also used by self-haulers, who
can bring garbage and recyclables to the
facility. The Skykomish facility is unstaffed;
payment is made at an automated gate
using a credit or debit card or pre-paid solid
waste disposal card. There are cameras at
the site to monitor activities, and division
staff makes regular visits to the site to
perform maintenance. In addition, the King
County Road Services Division has a facility The Skykomish Drop Box

next door, from which Road’s staff help monitor the site. The drop box met all the applicable evaluation criteria and
appears to provide an appropriate level of service for the area. The facility received a new roof in 2008, after the old
roof collapsed under record snowfall in January of that year.
Some rural area customers may be affected by changes to the urban transfer system, primarily self-haulers who
currently use the Houghton or Renton transfer stations. When a new urban facility is ultimately sited in the Northeast
service area, the facility location may or may not adequately meet the service needs of rural areas. Should it be
necessary, the division may consider siting drop box facilities to serve residents. Construction of regional transfer
stations in these rural areas is not being considered. The division recommends deferring decisions about whether to
site drop boxes in these potentially underserved areas and whether to close the Renton transfer station until after the
new urban transfer stations have been completed and the impact on service capacity has been fully evaluated.
City Mitigation
Transfer stations provide an essential and beneficial public service. However, the stations have the potential to cause
undesirable impacts on host cities and neighboring communities, such as increased litter, odor, noise, road/curb
damage, and traffic, as well as aesthetic impacts. The division works to mitigate these impacts in a number of ways,
such as collecting litter, landscaping on and around the site, limiting waste kept on-site overnight to reduce the
potential for odor, making road modifications, and siting facilities on or near major roadways to keep traffic off
local streets.
Seven cities in the division’s service area currently have county-owned transfer facilities within their boundaries:
•Algona – the Algona Transfer Station,
•Bellevue – the Factoria Recycling and Transfer Station,
•Enumclaw – the Enumclaw Recycling and Transfer Station,
•Kirkland – the Houghton Transfer Station,
•Renton – the Renton Transfer Station,
•Shoreline – the Shoreline Recycling and Transfer Station, and
•Tukwila – the Bow Lake Recycling and Transfer Station.
As new transfer stations are constructed in the near future, the division will work with host and neighboring cities to
build stations that are compatible with the surrounding community. For example, during the design of the Shoreline
Recycling and Transfer Station, the division worked closely with the community to identify impacts and mitigation
measures. One result is that transfer trailers drive directly from the station onto Interstate 5 using King County Metro
Transit’s dedicated freeway ramps rather than city streets for access. In addition, sidewalks on nearby streets were
improved; a new walking path was constructed at nearby Ronald Bog Park; trees were planted; and the portion of
Thornton Creek that flows through the site underwent significant restoration. The transfer building was also moved
farther from residences and is fully enclosed to mitigate impacts from noise, odor, and dust.
The division has also worked closely with the City of Bellevue on the replacement of the Factoria Transfer Station.
The initial plan was for a new facility to be constructed on property that fronts lnterstate 90 adjacent to the south side
of the old station. However, as a result of discussions with Bellevue, the division purchased adjacent proper ty to the
northwest of the old station to complete the new facility.
The Amended and Restated ILA (included in its entirety in Appendix C) identifies the roles and responsibilities
of the county and the cities in the regional solid waste system. The county agrees to collaborate with host and
neighboring cities on both environmental review and project permitting. Additionally, the Amended and Restated ILA
Updated April 17, 2019
Att A Page 147
Ordinance 18893
5-24 2019 Comprehensive Solid Waste Management Plan - July 2018
recognizes that, in accordance with RCW 36.58.080, a city is authorized to charge counties to mitigate impacts directly
attributable to a county-owned solid waste facility. It must be established that such charges are reasonably necessary
to lessen or eliminate impacts and the revenue generated may only be used for impact-mitigation purposes. Direct
impacts may include wear and tear on infrastructure, including roads. The city and county will work cooperatively
to determine the extent of the impacts and appropriate mitigation payments and will document any agreement.
Mitigation, including any necessary analysis, is a cost of the solid waste system and as such would need to be included
in the solid waste rate.
Transfer Services after an Emergency
Relatively common emergencies, such as seasonal flooding and winter storms, as well as major events, such as
earthquakes, can create a significant amount of debris. Debris generated during these types of events can obstruct
roadways, cause power outages, and interrupt essential services. A coordinated and effective plan ensures that debris
is properly managed to lessen the impacts on communities, the economy, and the environment in the immediate
aftermath of an emergency without causing additional problems later in recovery.
To this end, the division prepared the King County Operational Disaster Debris Management Plan (Debris Management
Plan)(KCSWD 2009) for unincorporated King County. The Debris Management Plan is intended to facilitate rapid
response and recovery efforts during a disaster. The Debris Management Plan will be reviewed periodically, prior to
the storm season, and updated as needed.
The Debris Management Plan supports the 37 incorporated cities that are part of the King County solid waste system
with a framework and recommendations that can be used by the cities to develop their own operational disaster
debris management plans. The cities have the flexibility to develop a debris management plan that best addresses
their individual needs without compromising continuity within the county. Several cities have now adopted individual
plans. The City of Seattle has its own debris management plan and the City of Milton is participating in Pierce County’s
debris management program.
The county’s Debris Management Plan stipulates that during emergency response and recovery, the roles within the
King County solid waste system do not change. This means that the division will continue to accept municipal solid
waste at the transfer stations to the extent possible and will maximize recycling in accordance with RCW 70.95.010 (8)
and KCC Title 10. The transfer facilities will not be used for disposal of disaster debris that could be recycled.
The debris created by a larger event, such as an earthquake, would likely consist primarily of recyclable materials, such
as concrete, metal, and wood. The division’s Debris Management Plan is coordinated with emergency plans prepared
by other jurisdictions to maximize the recycling of these materials. The division works with the King County Regional
Communications and Emergency Coordination Center (RCECC) and the Local Hazardous Waste Management Program
to coordinate public information and help cities and residents identify recycling options in the event of a debris-
causing emergency. Recycling the majority of emergency debris will maximize the division’s capacity to continue to
handle municipal solid waste over the short- and long-term.
In the event of an emergency, transfer services may be suspended in the short-term. The division’s priorities are to:

The division will maximize the use of existing transfer facilities after an emergency through operational measures
such as increased staffing or hours. If some transfer facilities are closed or damaged as a result of the event,
customers will be rerouted to remaining stations, and commercial haulers may be routed directly to Cedar Hills landfill
Additionally, the division and the cities may establish temporary debris management sites where debris can be stored
until it can be sorted for recycling or proper disposal. It is recommended that potential sites in unincorporated
King County and in cities be identified by each jurisdiction in advance of an emergency. The acceptance policies at
these sites would be determined in response to the nature of the event and the debris that is generated.
Processing Collected Materials
Processing Commingled Recyclables
The division expects that the private sector will continue to expand processing capacity for commingled recyclables
as the need arises. In addition, numerous other private-sector facilities have emerged across the county where
individual residents and businesses can bring source-separated recyclables, from paper, cans, and bottles to printer
cartridges and cellular telephones, for processing.
While the conversion to commingled collection makes recycling easier for consumers and has resulted in increased
recycling, it presents some challenges for the recovery and processing facilities. One of the challenges is cross-
contamination of materials as
they are sorted and separated.
This is a problem particularly
for the paper stream, where
materials such as plastic milk
jugs end up in the baled paper.
Plastic bags sometimes catch in
and jam the sorting machinery
at materials recovery facilities,
and they can blow around and
cause litter problems. Paper
mills overseas typically perform
additional sorting of the
materials to recover misplaced
recyclables; however, most
domestic paper mills dispose
of these materials. In the case
of glass, even small amounts of contamination in the sorted material can reduce the quality and affect the potential
end use of the recycled glass. These problems illustrate a fundamental conflict between the benefits of commingled
recycling (it makes collection easier and leads to increased recycling) and the need for the materials recovery facilities
and end users to minimize the costs of handling these materials.
For the processing of commingled recyclables to be most efficient, it is important that consumers are careful about
preventing contamination in the recycled loads by: 1) preparing recyclables for the collection cart (i.e., rinsing out
bottles and jars, breaking down cardboard boxes) and 2) placing materials in the proper collection container
3) closing container lids to keep materials dry. Contamination in the recyclables can cause a wide array of problems
during processing, which can lead to a reduction in the value of the materials processed for market or, in extreme

cases, the disposal of entire mixed loads. This issue can best be remedied through education programs on proper
recycling techniques offered through local governments and the collection companies. See Chapter 4 for a discussion
of issues regarding markets.
As the region moves forward, the recommended role of the county and cities is to focus on increasing the supply
and improving the quality of recyclable materials delivered to processors. The value of materials for recycling can be
maximized through public education – to decrease contamination in the recycling stream and ensure that materials
are properly prepared before being placed in the recycling container – and through market development – by
encouraging businesses to invest in technologies used to sort and process recyclables.
There are materials that present unique challenges or require more definitive decisions about the optimal way to
process them, such as container glass, food-contaminated paper, compostable and degradable plastic, plastic bag
and film, plastic caps, poly-coated paper, and shredded paper. The division, along with several cities, has participated
in the Northwest Region Commingled Workgroup to identify key issues with commingled collection and processing
and to develop recommendations for addressing them. The division will be working with the cities, the collection
companies, and processors to determine which of these recommendations will be implemented in King County.
Processing Organics
Organic waste (yard, wood and food waste) represents the largest recyclable commodity that is landfilled – 320,000
tons, more than a third of the total tons disposed at Cedar Hills landfill. Diverting these materials is key to meeting our
goals. Currently composting is the primary processing option for these materials in the region.
The volume of organics that is currently collected from King County businesses and residents for recycling is close to
exceeding the regional permitted capacity for such processing. The current amount of recycled organics represents 90
percent of the region’s processing capacity.

There is only one facility in King County permitted to handle food waste. Relying on one large regional facility
that is operating near its maximum permitted capacity is a concern, especially if the region wants to increase the
amount of organics that are recycled instead of being disposed. This facility is pursuing operational changes to help
mitigate odor concerns, and continues to be the subject of community odor complaints. One reason that capacity
is constrained in the region is because organics cannot be transported to Central/Eastern Washington for new
processing capacity because of the Washington State Apple Maggot Quarantine regulations (RCW 17.24).
Maintaining the quality of finished product is critical to compost markets, and processing challenges include:
•Contamination of composting
feedstocks, particularly from
glass and plastic film.
•Composting feedstocks are in
transition. Regional commercial
facilities were largely designed
for yard waste, not the mix of
food, yard, and compostable
packaging that is collected and
processed today. A need exists
for upgraded technology to
manage the new material mix.
•Processors have expressed a
desire to better anticipate the
future feedstock mix, noting a
need for better information on
volumes and incoming materials
to inform investments in capacity, equipment, and labor.
•Financing for technology upgrades at existing facilities.
•Composters report that market prices and sales for compost products have been stable. However, maintaining the
quality of finished product is key to maintaining adequate market demand for compost; processors must balance
the costs of adding processing steps (such as for additional contaminant removal) with maintaining competitive
market prices for finished product.
If organics diversion significantly increases in King County and the surrounding region, more processing capacity
will be needed. In order to significantly increase diversion of organic materials that are disposed from single and
multi-family homes and businesses, a regional dialogue with exploration of alternatives and solutions for expanding
capacity is necessary. This will help minimize environmental and community impacts related to regional organics
processing and ensure an adequate capacity and infrastructure is in place for regional organics processing, including
contingency plans in the event regional capacity is constrained.
A range of options should be pursued to address organics recycling capacity including continued organics and soils
education to promote the recycling and use of organics on landscapes, market development such as local buy-back
programs, the pursuit of new technologies and additional private or public infrastructure development.

Emerging Processing Technologies
Resource recovery goes beyond sorting to include technologies such as anaerobic digestion, advanced materials
recovery, pyrolysis, and gasification. Most of these technologies hold promise for the future but do not yet have
extensive track records in reliably handling the amount of waste in King County’s system. A brief discussion of
anaerobic digestion and advanced materials recovery follows. For a discussion on pyrolysis and gasification, see
Chapter 6, Landfill Management and Solid Waste Disposal.
Anaerobic Digestion
In 2016, the division hired HDR Engineering to evaluate options for adding anaerobic digestion to regional organics
processing (KCSWD 2017b). Anaerobic digestion is a biological process that transforms organic waste into renewable
energy, and in some situations, a useable residual by-product. HDR evaluated anaerobic digestion technologies using
both source-separated organics with minimal contamination, and municipal solid waste containing approximately
one third organic waste. The division required HDR to focus on local conditions, feedstocks, and markets.
While the study does not identify a clear role for anaerobic digestion in the county’s solid waste system, it does
recommend further research into several small-scale anaerobic digestion options for source-separated organics, with
varying levels of public and private sector collaboration. For instance, with grant money from the division, a small-
scale anaerobic digester is being piloted on Vashon Island. Source-separated organics-based anaerobic digestion
solutions are currently more affordable
and more reliable than municipal solid
waste-based systems. As a feedstock,
municipal solid waste typically benefits
greatly from advanced pre-processing,
which is costly and currently has mixed
success rates.
Currently, source-separated organics in
King County are managed by private-sector
companies, and do not even come to the
county’s transfer stations. However, source-
separated organics are likely the best
feedstock for successful anaerobic digestion
based on minimal contamination which
lowers pre-processing costs, eases the
anaerobic digestion process, and results in a
marketable organic by-product.
Advanced Materials Recovery
Advanced materials recovery as it is envisioned at the county recycling and transfer stations would involve both
floor sorting of recyclables by division staff and installing some mechanical sorting systems at select facilities (most
likely Bow Lake, the new south station, and any other new stations). An additional consideration might be a separate
advanced materials recovery facility (public, private, or a partnership) capable of processing sufficient mixed waste to
reach a 70 percent recycling rate for the county. This alternative would reach recycling goals more quickly than waste
prevention would, as it relies less on changes in customer behavior. However, feasible system configurations and cost
effectiveness are not yet known and would require more study, including a cost benefit analysis.

6-12019 Comprehensive Solid Waste Management Plan - July 2018
This chapter discusses the County’s current disposal practices at the Cedar Hills landfill, as well as presenting
important long-term disposal choices that must be decided as part of the approval of this Plan. It also provides
information on how special wastes are disposed, disposal of waste after an emergency is handled, and programs to
address disposal of illegally dumped waste are operated. Finally, it addresses how past disposal sites – closed landfills
– are managed.
Current Disposal at the Cedar Hills Landfill
For more than 50 years, King County has relied on the Cedar Hills landfill as a local means of cost-effective solid waste
disposal. Although another disposal method will ultimately be needed, the county has used several approaches
to maximize value for ratepayers and extend the landfill’s life beyond the 2012 closure date predicted in the 2001
Comprehensive Solid Waste Management Plan. Since 2001, new practices and policies have made better use of landfill
space, new capacity has been built, the tons going to the landfill have been reduced, and studies have identified
opportunities to further develop Cedar Hills to maximize disposal capacity through the planning horizon of this Plan.
The Solid Waste Transfer and Waste Management Plan (Transfer Plan), approved by the County Council in December
2007, included the following recommendation:
“Explore opportunities for taking advantage of available landfill capacity to extend the life of this
cost-effective disposal option; revise the Cedar Hills Site Development Plan and seek to maximize
the capacity (lifespan) of the landfill, subject to environmental constraints, relative costs to operate,
and stakeholder interests.”
To implement the Transfer Plan recommendation, the division is pursuing three primary strategies to extend
landfill life:
•Diversion of waste,
•Operational efficiencies, and
•New area development.
These three strategies seek to extend the life of the landfill by increasing landfill capacity and density, which are
defined as follows:
•Landfill capacity –the amount of space, often referred to as airspace, which is permitted and available for
disposal of waste. Landfill capacity is calculated based on the height, footprint, and slopes of the landfill.
•Density – how tightly materials are packed together, in this case solid waste in the landfill. A higher density
means more waste packed into a given amount of space. The density of solid waste within the landfill is a
function of both operational practices, the types of waste, and natural processes. Density is increased as waste
is compacted by heavy machinery on the face of the landfill and by the natural settling that occurs over time as
solid waste decomposes.

Diversion of Waste
Reducing the amount of waste delivered to the landfill (waste diversion) is the most effective strategy for extending
landfill life. The division will continue to practice current methods of waste diversion and may implement further
strategies, as discussed below and in more detail in Chapter 4, Sustainable Materials Management.
Current Strategies for Waste Diversion
Waste is currently diverted from Cedar Hills through two primary methods – waste prevention and recycling and a
ban on the acceptance of most construction and demolition debris.
Waste prevention and recycling efforts have proven a successful strategy for extending the life of the landfill. During a
20-year period, an estimated 10 million tons of materials that would otherwise have been disposed in the landfill were
recycled, extending the landfill’s life by approximately 10 years.
Banning most construction and demolition debris from Cedar Hills has also contributed to extending landfill life. Since
the disposal ban went into effect in 1994, an estimated 4 million tons of construction and demolition debris has been
diverted from the landfill (see Chapter 4, Sustainable Materials Management for more information about construction
and demolition debris recycling and disposal).
Potential Strategies for Waste Diversion
The division will continue to consider diverting a portion of the solid waste stream to another recycling, recovery,
or disposal option(s) while the landfill is still in operation. However, a cost-benefit analysis, including a comparative
analysis of greenhouse gas emissions, would precede any decision to pursue early diversion because the cost of
adding a new disposal method to the cost of operating Cedar Hills may outweigh the benefits of extending landfill
life. Possible diversion options include waste conversion technologies such as anaerobic digestion, demonstration
projects of other evolving technologies that promote resource recovery, or exporting some waste to an out-of-county
landfill. Environmental, social, economic, and other criteria also would play into any waste diversion decision.
Operational Efficiencies
The division has made a series of operational changes to increase landfill capacity and density. These changes
include reducing the amount of soil and rock buried in the landfill, using more efficient unloading and compaction
equipment, and taking advantage of natural settlement. Some of the key changes and efficiencies achieved are
described below:
•The division has implemented strategies to minimize the placement of soil in the landfill. For example, in the past,
six inches of compacted soil was used to cover the entire surface of the active solid waste disposal area at the end
of each working day. Daily cover serves to control litter and discourage foraging by animals, such as rodents and
birds. However, the use of soil consumes valuable landfill space. The division now uses retractable tarps to cover
most of the waste at the end of each day to reduce the amount of soil buried in the landfill. The tarps serve the
same function as daily soil cover. At the start of each day’s operations, the tarps are rolled up, and more solid waste
is placed directly on top of the previous day’s waste. Soil is still used to cover side slope areas. However, as much of
this soil as possible is removed before more waste is placed, and the soil is then reused. Together, these practices
have resulted in a reduction of the volume of soil buried in the landfill.

•Tippers now empty trailers and
containers rather than the walking
floor trailers previously used. Walking
floor trailers require a large, rock
covered surface for the trucks to
drive on as the walking floor rolls the
garbage out the back of the trailer.
These large rock surfaces are not
required with the tippers. Instead, the
garbage trailers are backed onto the
tipper, which tilts the trailer, allowing
the garbage to slide out of the back
and into the refuse area. The use of
tippers not only reduces the use of
rock, it also decreases unloading time
for each trailer by at least half, and
reduces damage to equipment
and tires.
• Heavier equipment and improved methods have increased waste compaction. Packing the waste to a greater
density allows more airspace for additional solid waste in each landfill area.
• Another strategy for increasing landfill capacity is taking advantage of the natural settlement that occurs as
waste placed in each area decomposes. As this natural settling occurs, the level of the landfill drops below the
permitted height, allowing more waste to be added to bring the height of a previously filled area back up to its
planned level. To take advantage of this natural settlement, the division has delayed final closure of Areas 5
and 6, and will delay final closure of Area 7, to allow settling to occur so that additional waste can be added
before final cover is applied.
With these operational changes, more solid waste can be placed within the already designed and permitted refuse
areas. The division will continue to pursue these and other best management practices that preserve airspace and
make more efficient use of landfill capacity. The division will also work with subject matter experts to determine
best practices related to use of top lifts and temporary covers, including how long temporary covers should be
used prior to applying final cover. The division will provide a report on the best practices with implementing
actions to the King County Council no later than April 1, 2020.
New Area Development
During 2009 and 2010, the division explored alternatives for developing new refuse areas to extend the landfill life.
A wide range of alternatives was originally identified. Based on a preliminary assessment of operational and
engineering feasibility, as well as likely environmental impacts, five action alternatives were developed that would
extend landfill life for an additional three to 13 years beyond the then projected closure date. The environmental
impacts of these alternatives were evaluated in an environmental impact statement (EIS), with the Final EIS issued
in July 2010. The EIS determined that none of the five action alternatives would result in any significant
unavoidable adverse environmental impacts compared with the no action alternative (KCSWD 2010a).
The preferred alternative from the Final EIS develops 56.5 acres for a new Area 8 in the southwestern portion of the
landfill and extends landfill life for eight to nine years. It maximizes the use of readily available space at the landfill,
with the least amount of disruption to existing landfill structures. Garbage shall not be disposed of, nor soils be
stockpiled, within 1,000 feet of the property line at the landfill, in accordance with the Settlement Agreement. At the
same time, this alternative preserves the flexibility to implement further development should it be necessary in the
future and balances the cost of future development and operations with savings to the ratepayer.

Developing a new area requires extensive excavation and preparation
Permitted Capacity Planned for Cedar Hills through 2028
Cedar Hills has built capacity remaining in four areas (Areas 5, 6, 7, and 8). The estimated capacities are based
on the difference between existing landfill contours (September 2, 2017 aerial survey) and the approved design
contours at completion.
As the landfill ages, it settles. Airspace from settlement can be recovered for disposal. Settlement occurs due to
consolidation and to loss of mass from leachate and more importantly, gas production. As gas is collected, it is
removed from the landfill. The airspace gas once occupied consolidates and the landfill settles. Soil surcharge
can be used to accelerate settlement. Areas 5 and 6 both have areas of soil stockpiled over them to accelerate
settlement. This soil will be recovered later for other uses. Cedar Hills landfill has additional planned capacity in
Area 8. Area 8 is currently under construction, which began in 2017 and will be ready for use in 2018. In
addition to Area 8, a top lift over Areas 7 and 8 is planned to bring those areas to a permitted maximum design
elevation of 800 feet. Such activity would be done only to the extent that such activity would be consistent
with the terms and conditions of the Settlement Agreement, which requires King County to make a good faith
effort to keep the maximum height of areas 5, 6, and 7 of the Landfill at or below 788 feet above sea level.
The table below presents current and planned capacity in cubic yards and tons by area, as of September 2,
2017. It is based on an air space utilization of 1,600 pounds of refuse disposed per cubic yard of air space
consumed, and an average yearly 1,025,000 tons (forecasted between 2017 and 2028). 1,600 pounds per cubic
yard is the airspace utilization achieved in Area 7 using current operational practices (compaction, daily cover
usage, and rock recovery). The terms and conditions of the Settlement Agreement may impact the actual
utilization of the Area Capacity described in the table.

The Next Disposal Option
A Disposal Option Must Be Selected as Part of This Plan’s Approval
With permitted capacity (Area 8) at the landfi ll predicted to be used by 2028, the disposal option for beyond 2028 must
be selected. The selection is needed to provide substantial lead time to complete fi nancial, operational, and
infrastructure preparations, including completion of environmental review under the State Environmental Policy Act
(SEPA). Interlocal agreements also require the county to consult with partner cities at least seven years before Cedar
Hills closes, triggering a consultation in 2021 if no new Cedar Hills capacity is built. For these reasons, selecting a
disposal option as part of approval of this Plan is essential to ensure there is no gap in the division’s ability to dispose
of waste and meet contractual obligations.
Further Development of Cedar Hills is Recommended
For the Public Review Draft Plan issued in January 2018, the division used information from the Conversion Technology
Report (R.W. Beck 2007), the Waste-to-Energy Study (Normandeau 2017), and an updated Cedar Hills Site Development
Alternatives Final Report (KCSWD 2017a) to identify three options to meet the county’s disposal needs after currently
permitted capacity at Cedar Hills is used: 1) Further develop Cedar Hills, 2) waste export, and 3) waste to energy (mass
burn) facility. After public comment and careful consideration of the three disposal options, the option to further
develop the Cedar Hills Landfi ll is recommended.
This recommendation will further develop Cedar Hills to maximize disposal capacity, extending the division’s over 50-
year practice of managing its waste locally. The increased capacity shall not all result in either disposal of garbage or
stockpiling of soils within 1,000 feet of the property line at the landfill, in accordance with the Settlement Agreement,
but will develop new cells within the existing footprint of the landfi ll and increase the height from the permitted 800
feet up to 830 feet, only to the extent that such activity would be consistent with the terms and conditions of the
Settlement Agreement, which requires King County to make a good faith effort to keep the maximum height of areas
5, 6, and 7 of the Landfill at or below 788 feet above sea level. Based on the 2018 tonnage forecast, maximizing the
development of the landf ill should extend capacity through the planning horizon of this Plan. Landf i ll life could be
extended if recycling increases, recessions occur, or more complex development approaches are used. To account for
emerging technologies, the next disposal option after Cedar Hills is not specifi ed in this Plan, but would be evaluated
in collaboration with regional partners prior to the next Plan update to ensure no gap in service. The recommended
further development is consistent with county policy to maximize the life of the Cedar Hills landfi ll. The Conversion
Technology Report (R.W. Beck 2007) and more recent division analysis concluded that Cedar Hills disposal is the most
economical way to handle King County’s waste. Other advantages include the division’s experience in landfi ll operation,
availability of space in a county-owned landfi ll with state of the art environmental controls, and collection of landfi ll gas
to produce renewable energy.
Developing Cedar Hills to the maximum extent feasible has the lowest rate impact of the three options considered,
the lowest greenhouse gas emissions and the lowest risk because of long-term experience in its operation. Other
benefi ts include that waste created in King County will continue to be managed locally, the division will maintain
control over the system, and landfi ll gas will continue to be delivered to the Bio-Energy Washington facility, resulting in
pipeline-quality natural gas, revenue for the division, and reduced greenhouse gas emissions. Table 6-1 includes a
comparison of key attributes of the three options.
To reduce impacts on neighboring communities, King County shall implement a bird management plan.

Models used by Regulatory Agencies to Calculate Greenhouse Gas Emissions
• The Waste Reduction Model (WARM) is a U.S. Environmental Protection Agency (EPA)-approved
decision tool for estimating relative lifecycle greenhouse gas emissions associated with disposal
options such as landfi lling, composting, mass burn, or anaerobic digestion. WARM answers the
question: Which of my next disposal options result in the lowest lifecycle greenhouse gas emissions,
accounting for both emissions and off sets?
WARM requires a profi le of disposed materials, which was drawn from the division’s 2015 Waste
Characterization. WARM then assigns emissions to the materials and converts the emissions into
metric tons of carbon dioxide equivalents (MTCO2e). Each material’s emissions represent lifecycle
emissions from mining to manufacturing to disposal. Because those emissions did not happen in
a single year or place, WARM results cannot be directly ascribed to a particular year or facility site.
WARM emissions are not precise – they represent the relative emissions of diff erent choices
(i.e. Option A has lower emissions than Option B). WARM results from this plan’s landfi ll options show
negative values largely due to off sets created by displacing fossil fuels with landfi ll-derived gas and
sequestration of carbon due to burial of organics.
• The eGGRT model creates a greenhouse gas (GHG) inventory of emissions from a specifi c facility
(such as a landfi ll or mass burn facility) in a given year. This model answers the question: What are the
emissions from historically disposed materials at my landfi ll this year?
eGGRT default values can over-ride site-specifi c data so that model results and facility monitoring
data may not entirely agree. The division reports eGGRT-estimated Cedar Hills landfi ll emissions each
year for the Washington Department of Ecology and EPA. Year-to year eGGRT emission changes from
that specifi c facility can be tracked and compared with emissions from other facilities. The agencies
also use the results to set priorities for developing facility emission-reduction programs.

Other Long-Term Disposal Options Considered
Waste export and a waste to energy (mass burn) facility (described below) were also considered as disposal options
in the Public Review Draft Comp Plan. Those options are not recommended as the next disposal option after current
permitted Cedar Hills capacity (Area 8) is used in 2028, but could be undertaken after an expanded Cedar Hills ultimately
closes. This plan does not consider the option of developing a replacement landfi ll either in King County or in another
county, in keeping with policy established in the 2001 Plan. Conditions in King County such as land availability,
environmental considerations, public acceptance, cost, and other issues would impede any eff ort to site a replacement
landfi ll in the county. In addition, there are existing landfi lls outside of King County with signifi cant capacity available.
Waste Export
This option would export waste via rail to an out-of-county landfi ll after permitted capacity at Cedar Hills is used
by 2028. Waste export by rail is a proven disposal option used by neighboring jurisdictions, including the City of
Seattle and Snohomish County. There are several regional landfi lls available by rail with combined capacity suffi cient
to handle the county’s waste in the long term (KCSWD 2017c). This option would transfer a signifi cant portion of
the County’s waste management activities into the private sector for long haul and landfi lling. This option is not
recommended as the next disposal option after 2028 for several reasons. It has higher costs than further development
of the Cedar Hills landfi ll. It requires modifying transfer stations for rail-ready transport, division operational changes,
and requires suffi cient lead time for contracting for services.
The Waste Export option would require all of the county’s waste to be exported on trains. According to the
Washington State Freight Rail Plan, it is unclear if the freight rail system will have adequate rail capacity by 2028
(Normandeau 2017) to accommodate all of the county’s waste. In addition, according to the Washington State
Department of Transportation 2014 “Landslide Mitigation Action Plan,” rail service can be disrupted by landslides and
fl ooding. If service interruptions stretch from days to weeks, unsanitary conditions could occur at transfer stations
and eventually in the neighborhoods where collection services must be stopped. Scarce rail capacity and service
disruptions could increase costs and require robust contingency planning.
Waste to Energy Facility
Under this option, all of the region’s municipal solid waste would be directed to a waste to energy facility built in King
County when current permitted capacity at Cedar Hills is reached by 2028. As discussed previously, a recent study
identifi ed a mass burn facility as the best waste to energy technology for consideration by King County (Normandeau
2017). Mass burn facilities operate successfully in many parts of the U.S. and the world.
To handle the county’s projected tonnage, the facility would require approximately a 40 acre site and be designed to
handle 5,000 tons-per-day so that it could operate 20 years before further disposal capacity is needed. After 20 years,
an added/expanded waste to energy facility or other disposal method would be required. A waste to energy facility
would reduce waste to ash 90 percent by volume and 75 percent by weight, while off setting some costs through the
sale of electricity and increasing recycling by as much as two percent by recovering metals after the waste is burned.
Non-processable, bypass waste, and ash would be transported to an out-of-county landfi ll by rail. This option is
not recommended as the next disposal option after 2028 for several reasons. It has the highest cost of the options
considered, it requires guaranteed amounts of consistent feedstock, has potential for ineffi cient operation in early
years when less capacity is used, and it has the highest greenhouse gas emissions of the options considered. As with
waste export, rail capacity constraints could disrupt export of ash and bypass waste. At 5,000 tons per day, the facility
would be among the largest in the world with associated implementation and siting risks.

Next Steps
Several actions will need to be taken in order to further develop the Cedar Hills Landfi ll beyond its current permitted
capacity. The following steps are needed at Cedar Hills to maximize disposal capacity:
•Move facilities currently located at the landfi ll that are on areas permitted for refuse disposal.
•Revise the Project Program Plan (KCSWD 2010b) and Cedar Hills Site Development Alternatives Final Report (KCSWD2017a) for the development of Cedar Hills and conduct a new SEPA environmental review, since increasing the heightof the landfi ll up to 830 feet was not considered in the 2010 EIS (KCSWD 2010a).
•Apply to Public Health – Seattle and King County for a permit modifi cation to allow the landfi ll to be expanded up to830 feet in height only to the extent that such modification would be consistent with the terms and conditions of theSettlement Agreement, which requires King County to make a good faith effort to keep the maximum height of areas5, 6, and 7 of the Landfill at or below 788 feet above sea level.
•Develop new landfi ll cells.
•While Cedar Hills expansion is underway, the region will need to review the latest technological advances and takethose into account during the next Plan update to properly evaluate disposal options for the ultimate closure of CedarHills.
Factors in Selecting a Long-Term Disposal Method
In cooperation with advisory committees, the division identifi ed several criteria be used in selecting a long-term
disposal option (see below). It is particularly important that disposal options are consistent with the
commitment of the County and its partner cities to Zero Waste of Resources by 2030. Any long-term disposal
option also must be responsive to increases in population, housing, and solid waste tonnage, as well as the
specifi c composition of King County’s waste. The 2018 tonnage forecast projects solid waste tons increasing to
1,275,000 tons by 2028 and continuing to grow, reaching 1,564,000 tons in 2040. This forecast assumes that
the region’s recycling rate remains at 52 percent.
King County's Office of Performance, Strategy and Budget will engage with the Solid Waste Division and the
regional partners to develop a plan for long-term disposal, to be recommended to the King County Executive,
who will transmit legislation to the King County Council implementing the next long-term disposal method.
The Executive will transmit a progress report that outlines how this plan will be developed, including timing
for development and transmittal of this plan, to the Council by December 31, 2021.
•An inventory of birds at least seagull-sized or larger that inhabit the Cedar Hills Regional Landfill, including species and number of birds, to be updated annually;
•Design suggestions to minimize attractiveness of the site to birds;
•A description of proposed bird control methods including equipment, construction activities, permits required
(including federal and state fish and wildlife permits), and other operation and maintenance requirements related to
bird control;
•Description of staff resources and training needed to implement the control plan thoroughly and completely;
•Performance metrics related to bird management; and
•A monitoring plan to, on at least an annual basis, assess the efficacy of the bird management plan and allow further adaptation and improvement of the plan. It will also provide a basis for determining if bird use of the area changes through time.
Given the longer life of the facility, King County will develop and implement a bird management plan for the Cedar Hills
Regional Landfill. The bird management plan shall include at least the following elements:
In recognition of the longer life of the landfill and to ensure transparency of landfill operations, the solid waste division
shall transmit to the council each year the annual report submitted to the local health jurisdiction and the department
of ecology, as required by WAC 173-351-200 (11), as amended.
Even with further development, Cedar Hills landfi ll capacity will ultimately be exhausted and a new disposal option will
be needed. The next disposal option is not specifi ed in this plan so that the latest technological advances can be
considered when the choice is made. The Transfer Plan suggested that one disposal option - waste export - is best
evaluated within 5 years of initiating service to ensure decisions consider current market conditions. Other disposal
options such as waste to energy likely require a longer lead time. Although the Amended and Restated Interlocal
Agreement requires consultation with cities at least seven years before Cedar Hills closes, evaluation of the next disposal
option should begin prior to the next Plan update to ensure enough time for method selection, planning, and
implementation.

handle all or specific components of the county’s waste stream in the future (RW Beck 2007, KCSWD 2014a, and

Screening and Evaluation Criteria for Disposal Options
The division, in collaboration with its advisory committees, has developed criteria by which disposal
options may be screened and evaluated when making future decisions. The screening and evaluation
criteria fall into six categories, each with a number of sub-categories on the following page:
Updated April 17, 2019
Att A Page 165
Ordinance 18893
6-10 2019 Comprehensive Solid Waste Management Plan - July 2018
reports, and partnerships are forming to fund, build, and operate facilities. Meanwhile, jurisdictions are undertaking
rule-making efforts to define terms and establish regulations that both facilitate the development of sustainable
technologies and protect the environment and the public. Waste conversion technologies are also now being defined
separately from incineration, e.g., “Waste conversion technologies are non-incineration technologies that are used to
convert the non-recyclable portion of the municipal solid waste stream to electricity, fuels, and/or industrial chemical
feedstocks” (SWANA 2011).
Waste conversion technologies use thermal, biological, or chemical processes that are sometimes combined
with mechanical processes. Technologies using a thermal process include pyrolysis, gasification, and plasma arc
gasification. Hydrolysis/fermentation, anaerobic digestion, and aerobic composting use biological processes.
Depolymerization uses a chemical process.
The feedstock used by waste conversion technology systems can be municipal solid waste; selected materials
removed from municipal solid waste, such as organics; or municipal solid waste combined with sewage sludge. Each
system has unique requirements regarding the types, size, and amount of feedstock processed per day.
Below is a sampling of conversion technologies, as described by Jeremy K. O’Brien of the Solid Waste Association of
North America (SWANA 2011). These technologies are not currently considered to have the capability to reliably and
cost-effectively handle all the materials in the regional system.
Gasification is a commercially proven manufacturing process that converts such hydrocarbons as coal,
petroleum coke, biomass (such as wood and agricultural crops or wastes) and other organics to a synthesis
gas (syngas), which can be further processed to produce chemicals, fertilizers, liquid fuels, hydrogen, and
electricity. In a gasification facility, hydrocarbon feedstock is injected with air or oxygen and steam into a high-
temperature, pressurized reactor until the chemical bonds of the feedstock are broken. The resulting reaction
produces the syngas. The syngas is then cleansed to remove such impurities as sulfur, mercury, particulates,
and trace minerals.
Terms
Waste conversion technologies are non-incineration technologies that use thermal, chemical, or
biological processes, sometimes combined with mechanical processes, to convert the unrecycled
portion of the municipal solid waste stream to electricity, fuels, and/or chemicals that can be used by
industry.
Incineration is a disposal method that converts waste materials into ash, flue gas, and heat using
controlled flame combustion.
Waste-to-energy technologies recover energy from municipal solid waste and include both waste
conversion technologies and incineration with energy recovery, such as mass burn waste-to-energy,
refuse-derived fuel, and advanced thermal recycling.
Systems are unique technological methods for processing specified feedstock that are developed and
patented by companies.
Feedstock is the input material used by waste conversion and waste-to-energy technologies.

Pyrolysis is a process that involves the thermal decomposition of feedstock at high temperatures
(750°F–1,500°F) in the absence of air. The resulting end product is a mixture of solids (char), liquids (oxygenated
oils), and gases (methane, carbon monoxide, and carbon dioxide). The oils and fuel gases can be used directly
as boiler fuel or refined for higher-quality uses such as engine fuels, chemicals, adhesives, and other products.
The solid residue contains most of the inorganic portion of the feedstock as well as large amounts of solid
carbon or char.
Plasma arc gasification technology is a heating method that can be used in both pyrolysis and gasification
systems. This technology was developed for the metals industry in the late nineteenth century. Plasma arc
technology uses very high temperatures (7,000°F) to break down the feedstock into elemental by-products.
When municipal solid waste is processed, the intense heat actually breaks up the molecular structure of the
organic material to produce such simpler gaseous molecules as carbon monoxide, hydrogen, and carbon
dioxide. The inorganic material is vitrified to form a glassy residue.
Anaerobic digestion is the bacterial breakdown of organics in the absence of oxygen. It can occur over a wide
temperature range from 50°F to 160°F. Anaerobic digestion of municipal solid waste can occur naturally, as
in a landfill, or in a controlled environment, such as a municipal solid waste anaerobic digestion facility. In the
latter, municipal solid waste is first processed for removal of inorganic and recyclable components, reduced
in size, and then placed in an airtight vessel called a digester, where the process occurs. Biogas is one of the
by-products of anaerobic digestion facility and it can be used as fuel for engines, gas turbines, fuel cells, boilers,
and industrial heaters. It can also be used in other processes and in the manufacture of chemicals. Anaerobic
digestion would be a good option when the food waste is separated at its source from other wastes.
The division is committed to the continued exploration of these and other emerging technologies. In addition, the
division is monitoring changing definitions, legislation and regulations, companies, and partnerships.
Disposal of Special Wastes
Most of the waste delivered to the division’s facilities is municipal solid waste (garbage) from residential and non-
residential sources. A portion of the waste stream, however, requires special handling and waste clearance before
disposal because of legal, environmental, public health, or operational concerns. Of the approximately 800,000 to 1
million tons of solid waste disposed each year, between 6,000 and 9,000 tons is designated as special waste. These
special items include industrial wastes; asbestos-containing materials; off-specification, recalled, or expired consumer
products; over-sized materials; treatment plant grit and vactor wastes; and other miscellaneous materials. It does not
include moderate risk wastes.
The division continues to educate customers on the county’s waste acceptance policies through public outreach
materials and hands-on customer service. Since 1993, the division has conducted a waste screening program to
ensure that materials in the waste stream are handled in accordance with federal and state regulations (Resource
Conservation and Recovery Act, Title 40, Subtitle D and WAC 173-351). Under this program, waste screening
technicians, in cooperation with other staff, perform random manual and visual screening of incoming loads of waste
at each transfer facility and at Cedar Hills to identify and properly manage any potentially unacceptable wastes.
About 11,000 loads of waste are screened at division facilities each year. Waste screening, combined with ongoing
surveillance and control of incoming solid waste by transfer station and landfill operations staff, is a significant step
in the county’s solid waste enforcement program. In cases where special waste policies are repeatedly disregarded,
division staff enforces compliance through a progressive process of warnings, citations, and eventually fines for
improper disposal of special wastes.

Under the county’s Waste Clearance Policy PUT 7-2-1(PR) and Waste Acceptance Rule PUT 7-1-6(PR), the Special
Waste Unit provides a free service to customers to evaluate wastes and determine if they can be accepted for disposal
and under what conditions. Special waste staff process and provide more than 400 waste clearances for disposal
each year. Conditions for disposal could include wetting to control dust, bagging, hauling directly to the Cedar Hills
landfill, specific packaging and labeling requirements, separation from other waste in a special waste disposal area, or
certification of disposal by authorized landfill staff. Procedures for disposal of special waste are often defined by local,
state, or federal regulation.
The method for handling special wastes once the Cedar Hills landfill closes will be considered during the evaluation of
alternative disposal options.
Managing Illegal Dumping and Litter
Managing municipal solid waste that is dumped on open ground is one of the division’s responsibilities. Illegal
dumping and litter can cause environmental contamination and pose both safety hazards and risks to public health.
Addressing the issue of illegal dumping requires several coordinated programs and the participation of many county
departments, the cities, and other agencies. The division manages or participates in programs that strive not only to
reduce littering and illegal dumping on public and private property, but also to assist its victims.
Illegal dumping
Illegal dumping is a continuing problem for agencies, businesses, and the general public who find yard waste,
appliances, car bodies, and other wastes dumped on their personal property, on public property, and on road rights
of way. The division continues to lead the implementation of recommendations made in 2004 by a county task force
charged with strengthening and coordinating the county’s response to illegal dumping complaints. In 2008, the
County Council adopted an ordinance to refine the county’s role in enforcing laws that prohibit illegal dumping on
public and private lands.
The ordinance enhances the county’s authority
to cite and prosecute illegal dumpers. For
example, it allows the county to charge a
restitution fee to illegal dumpers and, in turn,
provide monetary relief to victims of the illegal
dumping. The fee can be waived if the illegal
dumper cleans up and properly disposes of
the waste.
Coordinating illegal dumping reporting and
response through the Illegal Dumping Hotline
(206-296-SITE) is a major element in the
county’s surveillance and control system for
illegal dumping.

dumping prevention programs, and the junk vehicle program.
Water and Lands Resources Division Investigates illegal dumping and litter complaints involving surface water.
Cities Enforce municipal littering and illegal dumping ordinances and provide cleanup of litter and illegally
dumped material from city streets and properties.
The division also developed a program called the Community Cleanup Assistance Program, which enables
environmental site inspectors from the county, cities, and other agencies to issue free disposal vouchers to property
owners who are victims of illegal dumping.
Community Litter Cleanup
The division’s Community Litter Cleanup Program, funded in part by a grant from Ecology, supports the cleanup of
litter and illegal dumpsites on public lands and waterways in King County. The program also supports prevention and
education, through advertising, signage, and other measures.
In 2016, litter crews cleaned up over 176 tons of debris from 151 sites. About 17 percent of the debris – including
items such as tires, appliances, and junk vehicles – was recycled.
Secure Your Load
In accordance with state law, since 1994 the division has assessed a fee to the drivers of vehicles with unsecured loads
arriving at its staffed transfer facilities and landfill. An unsecured load has not been fastened in or attached to the
vehicle with tarps, rope, straps, netting, or chains, so as to prevent any part of the load or the covering from becoming
loose, detached, or leaving the vehicle while it is moving.
Updated April 17, 2019

According to the Washington State Department of Ecology’s Focus on Secured Loads (Ecology 2009a), road debris
causes about 400 accidents every year on Washington State highways and roughly 40 percent of litter on highways
comes from unsecured loads.
The requirement to secure loads is in the “Rules of the Road” (RCW 46.61.655), which is enforced by the Washington
State Patrol. State law (RCW 70.93.097) and King County Code (Title 10.12.040) require the division to charge an
unsecured-load fee, which is assessed by scale operators.
In 2006, the division launched the Secure Your Load outreach program to raise public awareness of the importance
of securing loads. The division has worked closely with the King County Sheriff’s Office and the Washington State
Patrol to enforce the law, and with Ecology and the Maria Federici Foundation to raise public awareness. In 2013, to
strengthen its deterrent effect, the fee for an unsecured load arriving at a division facility was raised to $25. Division
staff have received training from the Washington State Patrol to help them accurately identify unsecured loads and
uniformly assess the fee. The increased fee for unsecured loads supports safe, clean communities.
Disposal Services after an Emergency
The King County Operational Disaster Debris Management Plan (Debris Management Plan)(KCSWD 2009) outlines the
process for managing disaster debris within the boundaries of unincorporated King County and for coordinating with
the 37 cities with which King County has interlocal agreements. The Debris Management Plan is aligned with other
national, state, and county plans, including the 2014 King County Comprehensive Emergency Management Plan, as well
as regulations and policies that will affect how King County manages disaster debris.
Debris management operations are grouped into three response levels – routine, medium, and high. The response
level is determined by the division based on the geographic scope and impact of an actual or anticipated incident.
Routine incidents are relatively common emergencies such as small landslides or minor flooding, which can be
supported with existing resources and require minimal coordination.
•Routine incidents are relatively common emergencies such as small landslides or minor flooding, which can be
supported with existing resources and require minimal coordination.
•Medium-impact incidents require more than routine coordination, and generally involve multiple jurisdictions.
These include incidents such as moderate earthquakes, minor or moderate flooding in multiple locations, and
storms with snow, ice, and/or high winds. The situation may require mutual aid or contract resources, and it may
be necessary for the King County Executive to proclaim an emergency.
•High-impact incidents require a high degree of coordination and generally involve requests for state and federal
assistance. These include incidents such as large earthquakes, severe flooding, or severe storms. In most cases,
an emergency will have already been proclaimed by the King County Executive.
A regional approach to planning is essential for managing the multi-jurisdictional impacts of emergencies in the
Puget Sound area and for coordinating the limited disposal capacity in western Washington. This disposal capacity is
subject to two major constraints. First, most jurisdictions in the region export their solid waste to landfills east of the
Cascade Mountains. Without local landfill space, disposal capacity relies on the region’s transportation network, which
could be compromised in a major emergency. Second, the only operational landfill in King County – Cedar Hills – does
not accept for disposal construction and demolition debris – the most common aftermath of high-impact incidents -
only municipal solid waste.
Updated April 17, 2019

Ordinance 18893
6-152019 Comprehensive Solid Waste Management Plan - July 2018
The coordinated regional Debris Management Plan emphasizes recycling to the extent possible. The plan calls for the
use of temporary debris management sites for storage of debris until it can be sorted for recycling or proper disposal.
The division has worked with the King County Regional Communications and Emergency Coordination Center
to coordinate public information and help cities and residents identify recycling options in preparation for and in
response to emergency events of all types.
The ability to respond after a major regional emergency is one criterion that will be used to select a disposal option to
be used once the Cedar Hills landfill closes.
Restoration of Closed Landfills
The division is responsible for maintaining and monitoring closed landfills that were constructed under different
standards than those that guide landfill development today. Depending on the year the landfill closed, a minimum
maintenance and monitoring post-closure period is specified in the Washington Administrative Code, but the timeline
is not definite in state law. Although most of the closed landfills have reached the end of the required minimum
post-closure period, regulations and the understanding of closure requirements have changed, requiring ongoing
maintenance and monitoring. See Figure 6-1 for the location of the closed landfills.
Post-Closure Monitoring and Maintenance
At seven of the nine closed Iandfills, the division routinely monitors groundwater, surface water, wastewater, and
landfill gas. The Bow Lake and Corliss landfills were excavated to build new transfer stations on site, so very little, if
any, waste is left and monitoring is no longer necessary. Studies are underway at the Vashon, Cedar Falls, Hobart, and
Enumclaw landfills to determine what additional actions are needed for these landfills to reach a stable state. When a
stable state has been reached, post-closure activities at these landfills may be reduced or terminated.
Under the current monitoring program, sampling data are collected from more than 180 groundwater, surface
water, and wastewater monitoring stations, and approximately 100 landfill gas monitoring stations. These data are
summarized in quarterly and annual reports submitted to the Washington State Department of Ecology and Public
Health. Public Health also routinely inspects all of the closed landfills.
The closed landfills were constructed under
different standards than those that guide landfill
development today. With the exception of
portions of the Vashon landfill constructed after
1989, they are unlined and do not, in some cases,
incorporate all of the environmental control
systems present in a modern landfill. Thus, the
unique characteristics of each site – in particular
the underlying geology, what lies downstream,
and the waste that was originally placed in the
landfill – play an important role in the post-closure
needs of the site. These factors also influence the
need for ongoing monitoring and maintenance of
the existing landfill control systems. Since all but
the Vashon closed landfill have reached the end A bioberm at the Cedar Falls closed landfill filters landfill gas

of their required post-closure periods, each is being evaluated to determine what actions are required to bring the
landfill to a stable state. In some cases, there may be no need to continue monitoring; at other sites, monitoring may
continue at a reduced frequency and for a reduced range of constituents found in the medium being tested.
When the Cedar Hills landfill reaches capacity and closes, the bottom liner, capped top, and extensive gas and
water control systems will inhibit releases to the environment for many years. Applicable regulations will define
the minimum post-closure period (currently 30 years). Landfill closure is guided by the Resource Conservation
and Recovery Act Title 40, Subtitle D, Part 258, Subpart F – Closure and Post-Closure Care, as well as Washington
Administrative Code 173-351. The post-closure period may be shortened or lengthened based on the perceived risk
to human health and the environment. After the post-closure period, there is expected to be some reduced level of
monitoring and care to ensure the integrity of the cap and other environmental controls.
Beneficial Reuse of Landfill Properties
The county continues to examine possibilities for the beneficial reuse of closed landfill properties. While the presence
of landfill control systems at these landfills can limit the types of beneficial reuse projects that can be implemented,
such as at the Enumclaw landfill, the county has been successful in converting several properties wholly or in part to
new purposes. Future beneficial uses also could create revenue opportunities.
Houghton landfill – Athletic fields were developed on the former Houghton landfill area.
Hobart landfill – Model airplane enthusiasts and an astronomy club use the open spaces of the Hobart landfill.
Duvall landfill – The county installed an 800-MHz radio tower outside of the refuse boundary of the Duvall landfill as
part of its Emergency Communications Project.
Cedar Falls, Duvall, and Puyallup/Kit Corner landfills – Walking and cycling trails in the property buffers are used
by area communities.
Other beneficial uses
The open spaces at closed landfills,
often grassy areas surrounded by
woods, provide habitat for diverse
species of plants and animals. Closed

other vegetation to improve ground cover and water quality, as well as perches and nesting boxes for hawks and owls.
The Cedar Falls and Duvall landfills are near the headwaters of large streams and provide cover and a source of food
for birds, deer, coyote, and other woodland animals. Managing these properties as green space helps support the
county’s goals and policies for habitat preservation and increases carbon sequestration (i.e., reduces the total carbon
emissions) at the properties.
Finding reuse opportunities for the closed landfill properties provides continued benefit to the surrounding
communities, but the uses need to be compatible with the ongoing environmental monitoring at the sites. The
division continues to explore beneficial reuse options for closed landfills, such as alternative energy farms (solar and
wind) and sustainable forestry.

Financial policies help guide the solid waste system’s operations and investments. This chapter first provides a brief
summary of the division’s financial structure, including descriptions of funding sources, revenues, and expenditures.
The remainder of the chapter describes a range of influences expected to have a financial impact on the division in
the future.
Funding of Solid Waste Services and Programs
King County’s solid waste transfer and disposal system is a public-sector operation that is funded almost entirely by
fees collected from its customers. The division is an enterprise fund, managing nearly all of its expenses with revenues
earned through these fees.
The fees charged at county facilities, called tipping fees,
pay for the operation and maintenance of transfer and
disposal facilities and equipment, education and promotion
related to waste prevention and recycling, grants to cities
to support waste prevention and recycling efforts, and
administrative operating expenses and overhead.
Tipping fees also pay for the construction of transfer
facilities. Bonds or loans may be used for large projects, but
repayment of this debt is funded by tipping fees.
As discussed later in this chapter, through transfers into
reserve funds, the fee paid for each ton of waste entering
the system today covers the expenses involved in disposal
of that waste, even if some costs are incurred decades in
the future. Using this financial structure ensures that the
full cost of solid waste handling is paid by the users of the
system.
A summary of the fund structure is illustrated in Figure 7-1
and discussed in the following sections.

Solid Waste Division Revenues
As mentioned earlier, the solid waste system is funded primarily by the tipping fees charged at division facilities.
The tipping fee is charged to the commercial collection companies that collect materials curbside and to residential
and business self-haulers who bring wastes to the transfer facilities themselves. In accordance with KCC 10.08.040,
the County Council establishes the fees charged at county solid waste facilities.
There are four main types of tipping fees:
Basic Fee – The per-ton fee charged to customers disposing of municipal solid waste at transfer facilities and to
curbside collection vehicles at the Cedar Hills landfill. The basic fee accounts for about 97 percent of tipping
fee revenues.
Regional Direct Fee – A discounted fee charged to commercial collection companies that haul solid waste to
Cedar Hills in transfer trailers from their own transfer stations and processing facilities, thus bypassing county
transfer stations.
Yard Waste and Clean Wood Fee – A fee for separated yard waste and clean wood delivered to facilities that have
separate collection areas for these materials.
Special Waste Fee – The fee charged for certain materials that require special handling, record keeping, or both, such
as asbestos-containing materials and contaminated soil. There are two different special waste fees that reflect the
greater or lesser expense involved in handling and tracking different materials.
Other fees are charged for recyclables, such as appliances. KCC 10.12.021.G authorizes the division director to set fees
for recyclable materials for which no fee has yet been established by ordinance. These fees may be set to encourage
recycling and need not recover the full cost of handling and processing. In accordance with state law (RCW 70.93.097),
the division also charges a fee to vehicles with unsecured loads arriving at any staffed King County transfer facility or
the Cedar Hills landfiII.
Figure 7-2 shows the breakdown of revenues as projected for 2017 and 2018 in the 2016 Rate Study. As shown, about
90 percent of the division’s revenue comes from tipping fees. The remainder of the division’s revenue comes from a
How Cities Fund Solid Waste Programs
Cities fund their solid waste and waste prevention and recycling programs in a variety of ways, and
the resources available to the 37 cities in the King County system vary widely. Some cities receive
revenue from fees paid for solid waste collection services. These fees may be paid directly to the
city or to the collection company depending on who provides the collection service – the city
itself or a commercial collection company – and what contractual arrangements have been made.
In some cases, the collection companies charge a fee that is passed on to the city to fund their
programs. Some cities also charge a utility tax. Another funding source for cities is state and county
grants (see Chapter 4, Sustainable Materials Management for more information about grants). For
cities that do not receive any revenue from collection, the only revenue sources for funding waste
prevention and recycling programs may be grants and the city’s general fund.
Updated April 17, 2019
Att A Page 183
Ordinance 18893

few additional sources. The most significant of those is the Local Hazardous Waste Management Program (LHWMP).
Other sources of revenue include revenue from the sale of landfill gas from the Cedar Hills landfill; interest earned
on fund balances; recyclables revenue, including revenue from both the sale of scrap metals received at division
transfer facilities and from a fee on recyclables collected in unincorporated areas; fees collected from construction
and demolition disposal; income from rental properties; fees collected on unincorporated area curbside accounts to
support waste prevention and recycling education; and Washington State Department of Ecology grants to help clean
up litter and illegal dumping throughout the county, as well as to support waste prevention and recycling. Based on
economic and market conditions, revenues from these sources and interest earned can vary considerably.
Construction and Demolition Debris Surcharge
Starting in September 2015, management of the county’s construction and demolition waste
changed. In the past, the division had contracts with two private companies – Republic Services
and Waste Management – to manage the majority of the county’s construction and demolition
debris. Under the new system, the division designates qualified facilities to accept and process
construction and demolition debris.
In 2016, the division banned disposal of construction and demolition materials that have stable
recycling markets. As future markets develop, more materials may also be banned. Materials that
are brought to a designated facility for processing, but cannot be recycled, will incur a $4.25 per
ton disposal surcharge that will be payable to the division. This system is designed to encourage
recycling of construction and demolition materials. For more information, see Chapter 4,
Sustainable Materials Management.

Solid Waste Division Expenditures
Division expenditures, can be divided into four broad categories: operating costs, support service costs, debt service,
and transfers to other solid waste funds. The division maintains a target fund balance – an average balance in the
Operating Fund sufficient to cover 30 days of direct operating expenses. Operating expenses are defined to exclude
reserve funds. A rate stabilization reserve allows the accrual of funds to smooth out rate increases over time.
Figure 7-3 uses 2017-2018 projections to illustrate the various division expenditures, which are described in the
following sections:
Operating Costs
Operating costs, which constitute the majority of all division spending, include the day-to-day expenses for transfer,
transport, and landfill operations, maintenance of equipment and facilities, and management of landfill gas and
wastewater. Operating costs also include business and occupation tax, and an emergency contingency to cover some
costs related to weather-related events or other small emergencies. In addition, all but one of the closed landfills have
met the obligatory number of years of post-closure care, but have on-going needs for monitoring and maintenance.
Since the post-closure period has expired and maintenance and monitoring is still required, those projects are now
funded by the Operating Fund.
Also included in the operating costs category is the rent that the division pays to the county’s General Fund for use of
the landfill property. Rent is based on a fair market property appraisal. An appraisal by Murray & Associates in 2012
determined a rent payment schedule for 2015 through 2025. Also included in operation costs are mitigation paid to
cities for impacts directly attributable to solid waste facilities (RCW 36.58.080) as well as other mitigation related to
construction or other activities as required by federal, state, and local regulations and permits. Similar to the cities'
authorization to receive mitigation, and due to the longer life of the Landfill, the Road Services Division of the
Department of Local Services will study the ability to charge the Solid Waste Division to mitigate impacts directly
attributable to the regional facility, including wear and tear on nearby roads.
Another expense in this category is recycling costs. This includes grants to the cities and other waste prevention and
recycling programs and services provided by the division.

Support Service Costs
This cost category includes functions that support operations, such as engineering, overhead, finance, administration,
and planning.
Debt Service
Debt service is the payment of interest and principal on bonds and loans. Major transfer facility capital projects are
generally financed by a combination of general obligation (GO) bonds backed by the full faith and credit of the
county’s General Fund and rate dollars in the Construction Fund. It is anticipated that with approval of the County
Council, GO bonds will be issued for future transfer facility capital projects. Repayment of the debt will not extend
beyond, and may be less than, the useful life of the facility. Additional factors that may be considered include but are
not limited to: changes in disposal method, length of the ILA, bond market/bond rates, and waste generation.
To date, Cedar Hills landfill capital projects are not funded through debt financing, but through the Landfill Reserve
Fund discussed later in this section.
Transfers to Other Solid Waste Funds
Transfers from the Operating Fund to reserve funds make up a portion of the division’s costs. These reserve funds
were established to ensure that the division can meet future obligations, or expenses, some of which are mandated
by law. Contributions to reserve funds are routinely evaluated to ensure they are adequate to meet short- and long-
term needs. Paying into reserve funds stabilizes the impact on rates for certain expenses by spreading the costs over a
longer time period, and ensures that customers who use the system pay the entire cost of disposal. The three reserve
funds – the Capital Equipment Recovery Program Fund, the Landfill Reserve Fund, and the Post-Closure Maintenance
Fund – are discussed below.
Bond proceeds and contributions from the Operating Fund to the Construction Fund are used to finance new
construction and major maintenance of division transfer facilities and some closed landfill mitigation projects.
Contributions from the Operating Fund to the Construction Fund result in less borrowing, and consequently, a lower
level of debt service.
The Capital Equipment Recovery Program Fund (CERP) is codified in KCC 4A.200.680. The purpose of the CERP is to
provide adequate resources for replacement and major maintenance of solid waste rolling stock (primarily long-haul
trucks and trailers) and stationary compactors. New
equipment is purchased from the Operating Fund,
but after the initial purchase, replacements are
funded from the CERP.
By accumulating funds in the CERP, the division
is able to cover the expense of replacing needed
equipment without impacting rates, even while
revenue fluctuates. Annual contributions to
the CERP are calculated by projecting future
replacement costs, salvage values, and equipment
life. Contributions are adjusted to reflect changes
in facilities and operations that affect equipment
needs. The contributions are held in an account,
earning interest, until needed.
The Landfill Reserve Fund (LRF), codified in
KCC 4A.200.390, covers the costs of four major
accounts maintained for the Cedar Hills landfill, which are described on the following page:

•New area development account – Covers the costs for planning, designing, permitting, and building new
disposal areas.
•Facility improvements account – Covers a wide range of capital investments required to sustain the
infrastructure and operations at the landfill, such as enhancements to the landfill gas and wastewater systems.
•Closure account – Covers the cost of closing operating areas within the landfill that have reached capacity.
Mandated by federal and state law, these contributions help the division prepare incrementally for the cost of
final closure of the entire landfill.
•Post-closure maintenance account – Accumulates funds to pay for post-closure maintenance of the Cedar Hills
landfill for 30 years. This account is also mandated by federal and state law.
The sum of all four accounts, based on projected cost obligations, makes up the LRF contribution from the Operating
Fund. Projected cost obligations are based on the current plan for the landfill. When Cedar Hills closes, the division
will discontinue its contributions to the LRF. After final closure, the balance of the LRF will be transferred to the Post-
Closure Maintenance Fund to pay for Cedar Hills’ post-closure maintenance and monitoring.
The Post-Closure Maintenance Fund, codified in KCC 4A.200.710, is a separate fund that pays for the maintenance
and environmental monitoring of the Vashon landfill – the only closed landfill that is still within the regulatory period
set in 40 CFR 258.61 and Washington Administrative Code 173-351-600 (see Chapter 6, Landfill Management and
Solid Waste Disposal).
In addition to the funds mentioned above, the
division is investigating the establishment of
an Environmental Reserve, as discussed in the
Amended and Restated ILA. The purpose of such a
fund would be to help to pay for any environmental
liabilities not already covered by system rates
or insurance. The fund would be retained for a
minimum of 30 years following the closure of the
Cedar Hills Landfill.
Target Fund Balance
The division’s current practice is to retain an average
balance in the operating fund sufficient to cover at
least 30 days of direct operating costs.
Minimum Rate Stabilization Reserve
FCS Group conducted a rate structure analysis
(KCSWD 2017d), and reported that the division suffered an 11 percent reduction in Basic Fee revenue over a two-year
period during the Great Recession. For comparison, during the more moderate 2001 Dot-Com Bust, Basic Fee revenue
decreased by four percent in that two-year period.
To mitigate the risks associated with a moderate-level economic recession, holding five percent of annual revenues as
a minimum Rate Stabilization Reserve balance would provide for a moderate-level recession slightly more severe than
the Dot-Com Bust, but not for an outlier like the Great Recession.
Preparing for two years of reduced revenues fits with the County’s two-year budgeting cycle. Presumably, the Council
would be able to pass any needed recession response measures within two years, and the division would not need to
carry excessive reserves. The division is developing specific procedures for maintaining recession reserve monies to
include access to and replenishment of funds.

Influences on Future Costs and Revenue
In addition to the unanticipated increases or reductions in tonnage due to the economy, there are other factors
that can be expected to influence costs and revenues. These factors, which can be projected and budgeted for with
varying degrees of certainty, are summarized below.
Interest Earnings
The division’s reserve funds are invested to earn interest during the years, or even decades, before the funds are
needed. This is particularly significant for the long-term Landfill Reserve Fund, which will finance landfill closure and
30 years of post-closure care, a period expected to run from about 2028 (the currently approved capacity) through
2058, or if expanded capacity is approved, for about 30 years after Cedar Hills reaches its maximum disposal capacity,
making interest earnings a considerable factor in the amount that needs to be put aside. In 2013, the value of interest
earned was less than inflation. Starting in 2018, a small increase in interest above inflation is expected through 2026.
The county is looking at how the funds might be invested differently consistent with County guidelines to earn a
higher rate of return.
Waste Prevention and Recycling
As discussed earlier, revenues from garbage tipping fees cover the costs of waste prevention and recycling services
and programs. This financing structure requires the division to estimate the effects of waste prevention and recycling
on garbage disposal to reasonably project future revenues.
While the revenue stream relies primarily on garbage tipping fees, the current priorities in solid waste management
are waste prevention and recycling, which lead to reductions in the amount of solid waste disposed and therefore
in revenues received. The reduction in the amount of waste received due to waste prevention, recycling and
product stewardship has been gradual, and the system has adjusted to lower revenues. Further reductions through
increasingly rigorous waste prevention and recycling efforts will continue to affect the revenues of King County and
other jurisdictions across the state. The state’s Moving Washington Beyond Waste and Toxics, 2015 Update recognizes
that, “Local governments in particular are concerned about how to sustain funding for programs when the goal is to
reduce waste disposal, the source of most funding” (Ecology 2015). The county completed a Sustainable Solid Waste
Management Study (KCSWD 2014a) that looked at multiple strategies, technologies and services that the division
could employ to increase recycling and manage solid waste. One of the strategies suggested by the study is to
develop a sustainable financing model that is aligned with waste prevention and recycling (KCSWD 2014a).
Increased waste prevention and recycling efforts have had positive influences on the financial aspects of the system
as well. As discussed in Chapters 4 and 6, waste prevention and recycling have contributed to extending the life of the
Cedar Hills landfill, which will save money for ratepayers. Another aspect of waste prevention and recycling that has
had a positive financial effect is product stewardship. Product stewardship shifts the management of materials at the
end of their life to the product manufacturer. This shift reduces the costs to cities and counties of managing products
such as televisions, computers, and fluorescent bulbs and tubes, to name a few. The savings are most substantial
for products that contain hazardous materials and are more difficult and expensive to manage within the public
collection, transfer, and disposal system.

Operational Efficiencies
The division continually seeks to eliminate
waste and variability in its operations. This
commitment ensures the division’s ability to
provide value to its customers, while improving
the quality of service, controlling costs, and
upholding the county’s environmental goals.
Examples of operational efficiencies that are
producing significant and long-term results are
discussed briefly below.
Landfill Tippers
The division uses tippers to empty garbage
from transfer trailers at the landfill. The tippers
replaced the use of older walking floor trailers
(see Chapter 5, Landfill Management and Solid Waste Disposal, for more details). Tippers save staff time and other
resources, as well as reduce equipment and tire damage.
Solid Waste and Cardboard Compactors
As discussed in Chapter 4, the transfer system in King County is undergoing major renovations to update station
technology, improve efficiencies, and enhance environmental sustainability. The installation of solid waste
compactors is one important component of that plan. The Bow Lake, Enumclaw, Shoreline, Factoria, and Vashon
stations currently have waste compactors. All newly constructed recycling and transfer stations will incorporate
compactors as well.
Compacting solid waste at the stations reduces the number of trips necessary to transport the waste by up to
30 percent. Fewer trips translate directly into lower costs for fuel, equipment, and staff. For instance, in the first six
months of operation at the Bow Lake Recycling and Transfer Station, the use of a compactor saved almost 900 trips
and over 8,400 gallons of diesel fuel.
In addition to solid waste compactors, the division is installing cardboard compactors at many of the stations. These
compactors will allow the division to reduce the number of trips needed to pick up the bales.
Potential Changes in the Fee Structure
The division may propose changes to the current fee structure in future rate studies. Possible changes include
establishing different customer classes, discounts for low income customers, and moving some costs from the fee
charged at transfer facilities and the landfill to a fee on the curbside collection bill. In the 2014 Sustainable Solid Waste
Management Study (KCSWD 2014), one of the recommendations was to look at revising the fee structure. The division
completed a rate restructure study in 2017 and will be discussing with stakeholders what a rate restructure might
entail (KCSWD 2017d).
To equitably allocate the benefits and costs of transfer system improvements, the division may consider different
customer classes. The customer classes would take into consideration the services provided, benefits received, use of
the system, and the costs (incurred or avoided), of providing those services. An example of a customer class would be
self-haul customers or commercial customers at the transfer stations.

Ordinance 18893
7-10 2019 Comprehensive Solid Waste Management Plan - July 2018
In 2010, legislation was passed authorizing the Washington Utilities and Transportation Commission to approve
discounts for low-income customers under certain circumstances. For the first time, the division is proposing a low-
income discount in its 2019-2020 Rate Proposal (KCSWD 2018b).
Before changes to the fee structure are proposed, the division is studying a number of factors, including the impact
on revenue and cost, equity issues, and system-wide financing implications. These factors will be considered in future
rate studies.
Closure of the Cedar Hills Regional Landfill
When Cedar Hills reaches capacity and closes, the division’s solid waste tipping fee is expected to increase to cover
the cost of using an alternate means of disposal. Whether it is export to an out-of-county landfill, disposal at a waste-
to-energy facility, or other conversion technology, past studies, as well as a recent preliminary study, indicate that the
cost for disposal after Cedar Hills closes will be higher (KCSWD 2017c) (see Chapter 6, Landfill Management and Solid
Waste Disposal for further discussion).
New Revenue Sources
The division is continually exploring new sources of revenue to help offset reductions in tonnage. Cities may also want
to consider additional funding sources to support their solid waste and waste prevention and recycling programs.
Sales from the Landfill Gas-to-
Energy Facility
An example of the successful development of a
revenue source is the sale of landfill gas. In 2009,
a landfill gas-to-energy facility began operations
at Cedar Hills, and the division began to receive
revenues from the sale of landfill gas. The facility,
which is privately owned and operated by Bio
Energy Washington , converts methane collected
from the landfill into pipeline quality natural gas,
which it sells to Puget Sound Energy.
In addition, the environmental attributes from
the pipeline quality gas produced by the landfill
gas-to-energy facility at Cedar Hills have value
in the market and offer another ongoing source
of revenue. The division, rather than the owner of the landfill gas facility, Bio Energy Washington , has contractually
retained the environmental attributes associated with the project. In January of 2011, the County Council
unanimously approved an ordinance authorizing the division to enter into a contract to sell the environmental
attributes associated with the landfill gas-to-energy project to Puget Sound Energy. This contract is structured so

that the county shares in profits that Puget Sound Energy gets when selling the environmental attributes associated
with the gas. The division receives revenue for both the gas and the environmental attributes associated with the gas.
The revenue received by the division is highly volatile, and has ranged from $1 to $7 million per year, depending on
production rates and the market price.
Resource Recovery at Transfer Stations
Significant amounts of recyclable materials – notably wood, metal and cardboard - are disposed at the transfer
stations. The division is implementing new approaches, such as sorting the recyclable materials on the tipping floor
and banning certain materials from disposal, to recover more of these materials at the transfer stations. Revenues
from the sale of these materials help offset the costs of sorting and equipment. (see Chapter 5, Solid Waste Transfer
and Processing System for further discussion).
Fees from Materials Collected at the Transfer Stations
King County Code (KCC 1 0.12.021.G) does not require that fees for recyclables recover the full costs of handling and
processing recyclable materials. Therefore the fees can be set lower to encourage recycling over disposal. In fact,
for materials such as the standard curbside recyclables collected at the transfer stations, there is currently no fee at
all, even though the division pays the cost of transport and processing. As collection services for more recyclable
materials are added at transfer facilities and more tons of materials are recycled, fees will be evaluated on a regular
basis and adjusted as necessary to optimize the financial and environmental benefits.
The division will continue to explore innovative opportunities, such as partnering with the private sector or other
public agencies, to earn additional revenues and achieve savings through operational efficiencies. Although, these
efforts may involve relatively small amounts of money, cumulatively they contribute to stabilizing rates for solid
waste customers.

1. DEMOGRAPHICS
The King County solid waste system comprises 37 of the 39 cities in the county (including all but the cities of
Seattle and Milton) and the unincorporated areas of King County. In all, the county’s service area covers
approximately 2,050 square miles. There are about 1.45 million residents and 840,000 people employed in the
service area.
1.1. Population
1.1.1. Population for the entire King County
Year 1: 2,166,600
Year 3: 2,257,800
Year 6: 2,297,000
1.1.2. Population for the King County solid waste system
Year 1: 1,472,384
Year 3: 1,503,363
Year 6: 1,533,750
1.2. References and Assumptions
Projections for population are based on data developed by the Puget Sound Regional Council (PSRC; 2017).
Data provided by PSRC are based on U.S. Census and other data sources and developed in close cooperation
with the county and the cities.

2. WASTE STREAM GENERATION
2.1. Tonnage Recycled
Year 1: 1,032,873 (52% recycling)
Year 3: 1,090,977 (52% recycling)
Year 6: 1,179,649 (52% recycling)
2.2. Tonnage Disposed
Year 1: 953,421
Year 3: 1,007,056
Year 6: 1,088,907
2.3. References and Assumptions
The division uses a planning forecast model to predict future waste generation, which is defined as waste
disposed + materials recycled. The forecast is used to guide system planning, budgeting, rate setting, and
operations. The primary objectives of the model are to: 1) estimate future waste disposal and 2) provide
estimates of the amount of materials expected to be diverted from the waste stream through division and city
waste prevention and recycling programs. The tonnage forecast is described in more detail in Chapter 3 of the
Plan.
3. SYSTEM COMPONENT COSTS
This section addresses costs associated with current programs and those recommended in the draft plan.
3.1. Waste Reduction and Recycling Programs
Many programs address waste reduction and prevention as well as recycling; therefore, they are presented
here together.
3.1.1.Programs
Education and promotion campaigns

Operations, and ancillary operating units.
3.6.3 Funding mechanisms
Around 90 percent of the division’s revenue comes from tipping fees charged at transfer facilities
and the Cedar Hills landfill. The remainder comes from a few additional sources, including interest
earned on fund balances, a surcharge on construction and demolition (C&D), revenue from the
sale of recyclable materials received at division transfer facilities, a fee on recyclables collected in

unincorporated areas, and grants to help clean up litter and illegal dumping throughout the
county and to support WPR. Other than grant funds, all revenue sources support all programs.
3.7 Other Programs
3.7.1 The Transfer Services System Program is described in Chapter 5 of the Plan. It includes the
division’s recycling and transfer stations, private facilities that handle construction and demolition
debris (C&D), and household hazardous waste (HHW) service, which is covered in detail by the
Local Hazardous Waste Management Plan.
3.7.2 The division owns and operates eight transfer stations and two drop boxes. Allied Waste and
Waste Management own and operate facilities that handle C&D. The division operates HHW
service at its Factoria transfer station and provides Wastemobile service via a contractor.
3.7.3 The UTC regulates the C&D facilities.
3.7.4 Solid Waste Division Costs
3.7.4.1 Transfer facility operating and capital costs are estimated to be:
Year 1: $61,022,952
Year2: $68,229,939
Year 3: $80,090,023
3.7.4.2 HHW service costs are estimated to be: NA
3.7.5 The major funding source for division transfer operations is tipping fees. Capital costs are paid
from the construction fund; bond proceeds and contributions from the operating fund (tipping
fees) are deposited into the construction fund. The cost of providing HHW service is funded by the
LHWMP.
3.8 References and Assumptions
The estimate for year 1 costs is from actual 2018 costs to-date plus projected costs for the remainder of
the year; years 3 and 6 were increased to account for inflation, tonnage projections, and expected
program additions. The collection program estimates were derived using hauler reports and a projected
rate of population increase in King County. Numbers have been rounded in most instances.

AMENDED AND RESTATED SOLID WASTE
INTERLOCAL AGREEMENT
This Amended and Restated Solid Waste Interlocal Agreement (“Agreement”) is entered
into between King County, a political subdivision of the State of Washington and the City of
, a municipal corporation of the State of Washington, hereinafter referred
to as "County" and "City" respectively. Collectively, the County and the City are referred to as
the “Parties.” This Agreement has been authorized by the legislative body of each jurisdiction
pursuant to formal action as designated below:
King County: Ordinance No. __________
City: ________________________________________________
PREAMBLE
A. This Agreement is entered into pursuant to chapter 39.34 RCW for the purpose of
extending, restating and amending the Solid Waste Interlocal Agreement between the
Parties originally entered into in ____ (the “Original Agreement”). The Original
Agreement provided for the cooperative management of Solid Waste in King County for
a term of forty (40) years, through June 30, 2028. The Original Agreement is superseded
by this Amended and Restated Agreement, as of the effective date of this Agreement.
This Amended and Restated Agreement is effective for an additional twelve (12) years
through December 31, 2040.

B. The Parties intend to continue to cooperatively manage Solid Waste and to work
collaboratively to maintain and periodically update the existing King County
Comprehensive Solid Waste Management Plan (Comprehensive Plan) adopted pursuant
to chapter 70.95 RCW.
C. The Parties continue to support the established goals of Waste Prevention and Recycling
as incorporated in the Comprehensive Solid Waste Management Plan, and to meet or
surpass applicable environmental standards with regard to the Solid Waste System.
D. The County and the Cities agree that System-related costs, including environmental
liabilities, should be funded by System revenues which include but are not limited to
insurance proceeds, grants and rates;
E. The County, as the service provider, is in the best position to steward funds System
revenues that the County and the Cities intend to be available to pay for environmental
liabilities; and
F. The County and the Cities recognize that at the time this Agreement goes into effect, it is
impossible to know what the ultimate environmental liabilities could be; nevertheless, the
County and the Cities wish to designate in this Agreement a protocol for the designation
and distribution of funding for potential future environmental liabilities in order to protect
the general funds of the County and the Cities.
G. The County began renting the Cedar Hills Landfill from the State of Washington in 1960
and began using it for Disposal of Solid Waste in 1964. The County acquired ownership
of the Cedar Hills Landfill from the State in 1992. The Cedar Hills Landfill remains an
asset owned by the County.

H. The Parties expect that the Cedar Hills Landfill will be at capacity and closed at some
date during the term of this Agreement, after which time all Solid Waste under this
Agreement will need to be disposed of through alternate means, as determined by the
Cities and the County through amendments to the Comprehensive Solid Waste
Management Plan. The County currently estimates the useful life of the Cedar Hills
Landfill will extend through 2025. It is possible that this useful life could be extended, or
shortened, by System management decisions or factors beyond the control of the Parties.
I. The County intends to charge rent for the use of the Cedar Hills Landfill for so long as
the System uses this general fund asset and the Parties seek to clarify terms relative to the
calculation of the associated rent.
J. The County and Cities participating in the System have worked collaboratively for
several years to develop a plan for the replacement or upgrading of a series of transfer
stations. The Parties acknowledge that these transfer station improvements, as they may
be modified from time-to-time, will benefit Cities that are part of the System and the
County. The Parties have determined that the extension of the term of the Original
Agreement by twelve (12) years as accomplished by this Agreement is appropriate in
order to facilitate the long-term financing of transfer station improvements and to
mitigate rate impacts of such financing.
K. The Parties have further determined that in order to equitably allocate the benefit to all
System Users from the transfer station improvements, different customer classes may be
established by the County to ensure System Users do not pay a disproportionate share of
the cost of these improvements as a result of a decision by a city not to extend the term of
the Original Agreement.

Ordinance 18893
C-132019 Comprehensive Solid Waste Management Plan - July 2018
- 14 -
7.2.a A use valuation shall be prepared consistent with MAI accepted principles
for the purpose of quantifying the value to the System of the use of Cedar Hills Landfill for
Disposal of Solid Waste over a specified period of time (the valuation period). The County shall

8.1 Non-Environmental Liability Arising Out-of-County Operations. Except as
provided in this Section, Sections 8.5 and 8.6, the County shall indemnify and hold harmless the
City and shall have the right and duty to defend the City through the County's attorneys against
any and all claims arising out of the County's operations during the term of this Agreement and
settle such claims, provided that all fees, costs, and expenses incurred by the County thereby are
System costs which may be satisfied from Disposal Rates as provided in Section VII herein. In
providing such defense of the City, the County shall exercise good faith in such defense or
settlement so as to protect the City's interest. For purposes of this Section "claims arising out of
the County's operations" shall mean claims arising out of the ownership, control, or maintenance
of the System, but shall not include claims arising out of the City's operation of motor vehicles in
connection with the System or other activities under the control of the City which may be
incidental to the County's operation. The provisions of this Section shall not apply to claims
arising out of the sole negligence or intentional acts of the City. The provisions of this Section
shall survive for claims brought within three (3) years past the term of this Agreement
established under Section III.
8.2 Cooperation. In the event the County acts to defend the City against a claim under
Section 8.1, the City shall cooperate with the County.

acting within the scope of their authority. Transporters or generators of waste who are not
officers or employees of the City or County are not included as agents of the City or County for
purposes of this Section.
8.4 Each Party by mutual negotiation hereby waives, with respect to the other Party
only, any immunity that would otherwise be available against such claims under the Industrial
Insurance provisions of Title 51 RCW.
8.5 Unacceptable Waste
8.5.a All waste generated or collected from within the corporate limits of the
City which is delivered to the System for Disposal shall be in compliance with the Resource
Conservation and Recovery Act (42 U.S.C. § 6901 et seq.) (RCRA), chapters 70.95 and 70.105
RCW, King County Code Title 10, King County Board of Health Rules and Regulations, the
Solid Waste Division operating rules, and all other Federal, State and local environmental health
laws, rules or regulations that impose restrictions or requirements on the type of waste that may
be delivered to the System, as they now exist or are hereafter adopted or amended.
8.5.b For purposes of this Agreement, the City shall be deemed to have
complied with the requirements of Subsection 8.5.a if it has adopted an ordinance requiring
waste delivered to the System for Disposal to meet the laws, rules, or regulations specified in
Subsection 8.5.a. However, nothing in this Agreement is intended to relieve the City from any
obligation or liability it may have under the laws mentioned in Subsection 8.5.a arising out of the
City's actions other than adopting, enforcing, or requiring compliance with said ordinance, such
as liability, if any exists, of the City as a transporter or generator for improper transport or
Disposal of regulated dangerous waste. Any environmental liability the City may have for

releases of pollutants or hazardous or dangerous substances or wastes to the environment is dealt
with under Sections 8.6 and 8.7.
8.5.c The City shall hold harmless, indemnify and defend the County for any
property damages or personal injury caused solely by the City's failure to adopt an ordinance
under Subsection 8.5.b. In the event the City acts to defend the County under this Subsection, the
County shall cooperate with the City.
8.5.d The City shall make best efforts to include language in its contracts,
franchise agreements, or licenses for the collection of Solid Waste within the City that allow for
enforcement by the City against the collection contractor, franchisee or licensee for violations of
the laws, rules, or regulations in Subsection 8.5.a. The requirements of this Subsection 8.5.d shall
apply to the City's first collection contract, franchise, or license that becomes effective or is
amended after the effective date of this Agreement.
8.5.d.i If waste is delivered to the System in violation of the laws,
rules, or regulations in Subsection 8.5.a, before requiring the City to take any action under
Subsection 8.5.d.ii, the County will make reasonable efforts to determine the parties’ responsible
for the violation and will work with those parties to correct the violation, consistent with
applicable waste clearance and acceptance rules, permit obligations, and any other legal
requirements.
8.5.d.ii If the violation is not corrected under Subsection 8.5.d.i and
waste is determined by the County to have been generated or collected from within the corporate
limits of the City, the County shall provide the City with written notice of the violation. Upon
such notice, the City shall take immediate steps to remedy the violation and prevent similar
future violations to the reasonable satisfaction of the County which may include but not be

in this Subsection 8.5.d.ii shall obligate the City to handle regulated dangerous waste, as defined
in WAC 173-351-200(1)(b)(i), and nothing in this Subsection shall relieve the City of any
obligation it may have apart from this Agreement to handle regulated dangerous waste. If, in
good faith, the City disagrees with the County regarding the violation, such dispute shall be
resolved between the Parties using the Dispute Resolution process in Section XII or, if
immediate action is required to avoid an imminent threat to public health, safety or the
environment, in King County Superior Court. Each Party shall be responsible for its own
attorneys' fees and costs. Failure of the City to take the steps requested by the County pending
Superior Court resolution shall not be deemed a violation of this Agreement; provided, however,
that this shall not release the City for damages or loss to the County arising out of the failure to
take such steps if the Court finds a City violation of the requirements to comply with applicable
laws set forth in Subsection 8.5.a.
8.6 Environmental Liability.
8.6.a Neither the County nor the City holds harmless or indemnifies the other
with regard to any liability arising under 42 U.S.C. § 9601-9675 (CERCLA) as amended by the
Superfund Amendments and Reauthorization Act of 1986 (SARA) or as hereafter amended or
pursuant to chapter 70.105D RCW (MTCA) or as hereafter amended and any state legislation
imposing liability for System-related cleanup of contaminated property from the release of
pollutants or hazardous or dangerous substances and/or damages resulting from property
contaminated from the release of pollutants or hazardous or dangerous substances
(“Environmental Liabilities”).

8.6.b Nothing in this Agreement is intended to create new Environmental
Liability nor release any third-party from Environmental Liability. Rather, the intent is to protect
the general funds of the Parties to this Agreement by ensuring that, consistent with best business
practices, an adequate portion of Disposal Rates being collected from the System Users are set
aside and accessible in a fair and equitable manner to pay the respective County and City’s
Environmental Liabilities.
8.6.c The purpose of this Subsection is to establish a protocol for the setting
aside, and subsequent distribution of, Disposal Rates intended to pay for Environmental
Liabilities of the Parties, if and when such liabilities should arise, in order to safeguard the
Parties’ general funds. To do so, the County shall:
8.6.c.i Use Disposal Rates to obtain and maintain, to the extent
commercially available under reasonable terms, insurance coverage for System-related
Environmental Liability that names the City as an Additional Insured. The County shall establish
the adequacy, amount and availability of such insurance in consultation with MSWAC. Any
insurance policy in effect on the termination date of this Agreement with a term that extends past
the termination date shall be maintained until the end of the policy term.
8.6.c.ii Use Disposal Rates to establish and maintain a reserve fund to
help pay the Parties’ Environmental Liabilities not already covered by System rates or insurance
maintained under Subsection 8.6.c.i above (“Environmental Reserve Fund”). The County shall
establish the adequacy of the Environmental Reserve Fund in consultation with MSWAC and
consistent with the financial policies described in Article VI. The County shall retain the
Environmental Reserve Fund for a minimum of 30 years following the closure of the Cedar Hills
Landfill (the “Retention Period”). During the Retention Period, the Environmental Reserve Fund
Updated April 17, 2019

Ordinance 18893
C-192019 Comprehensive Solid Waste Management Plan - July 2018
- 20 -
shall be used solely for the purposes for which it was established under this Agreement. Unless
otherwise required by law, at the end of the Retention Period, the County and Cities shall agree
as to the disbursement of any amounts remaining in the Environmental Reserve Fund. If unable
to agree, the County and City agree to submit disbursement to mediation and if unsuccessful to
binding arbitration in a manner similar to Section 39.34.180 RCW to the extent permitted by law.
8.6.c.iii Pursue state or federal grant funds, such as grants from the
Local Model Toxics Control Account under chapter 70.105D.070(3) RCW and chapter 173-322
WAC, or other state or federal funds as may be available and appropriate to pay for or remediate
such Environmental Liabilities.
8.6.d If the funds available under Subsections 8.6.c.i-iii are not adequate to
completely satisfy the Environmental Liabilities of the Parties to this Agreement then to the
extent feasible and permitted by law, the County will establish a financial plan including a rate
schedule to help pay for the County and City’s remaining Environmental Liabilities in
consultation with MSWAC.
8.6.e The County and the City shall act reasonably and quickly to utilize funds
collected or set aside through the means specified in Subsections 8.6.c.i-iii and 8.6.d to conduct
or finance response or clean-up activities in order to limit the County and City’s exposure, or in
order to comply with a consent decree, administrative or other legal order. The County shall
notify the City within 30 days of any use of the reserve fund established in 8.6.c.iii.
8.6.f In any federal or state regulatory proceeding, and in any action for
contribution, money expended by the County from the funds established in Subsections 8.6.c.i-iii
and 8.6.d. to pay the costs of remedial investigation, cleanup, response or other action required

pursuant to a state or federal laws or regulations shall be considered by the Parties to have been
expended on behalf and for the benefit of the County and the Cities.
8.6.g In the event that the funds established as specified in Subsections 8.6.c.i-iii
and 8.6.d are insufficient to cover the entirety of the County and Cities’ collective Environmental
Liabilities, the funds described therein shall be equitably allocated between the County and
Cities to satisfy their Environmental Liabilities. Factors to be considered in determining
“equitably allocated” may include the size of each Party’s System User base and the amount of
rates paid by that System User base into the funds, and the amount of the Solid Waste generated
by the Parties’ respective System Users. Neither the County nor the Cities shall receive a benefit
exceeding their Environmental Liabilities.
8.7 The County shall not charge or seek to recover from the City any costs or
expenses for which the County indemnified the State of Washington in Exhibit A to the
Quitclaim Deed from the State to the County for the Cedar Hills Landfill, dated February 24,
1993, to the extent such costs are not included in System costs.
IX. CITY ADVISORY COMMITTEE
9.1 There is hereby created an advisory committee comprised of representatives from
cities, which shall be known as the Metropolitan Solid Waste Advisory Committee (“MSWAC”).
The City may designate a representative and alternate(s) to serve on MSWAC. MSWAC shall
elect a chair and vice-chair and shall adopt bylaws to guide its deliberations. The members of
MSWAC shall serve at the pleasure of their appointing bodies and shall receive no compensation
from the County.

King County Charter Section 270.30 and chapter 1.24 King County Code.
XI. COMPREHENSIVE SOLID WASTE MANAGEMENT PLAN
11.1 King County is designated to prepare the Comprehensive Solid Waste
Management Plan (Comprehensive Plan) and this plan shall include the City's Solid Waste
Management Comprehensive Plan pursuant to chapter 70.95.080(3) RCW.
11.2 The Comprehensive Plan shall be reviewed and any necessary revisions
proposed. The County shall consult with MSWAC to determine when revisions are necessary.
King County shall provide services and build facilities in accordance with the adopted
Comprehensive Plan.
11.3 The Comprehensive Plans will promote Waste Prevention and Recycling in
accordance with Washington State Solid Waste management priorities pursuant to chapter 70.95
RCW, at a minimum.
11.4 The Comprehensive Plans will be prepared in accordance with chapter 70.95
RCW and Solid Waste planning guidelines developed by the Department of Ecology. The plan
shall include, but not be limited to:
11.4.a Descriptions of and policies regarding management practices and facilities
required for handling all waste types;

11.4.d Operational plan for the elements discussed in Item c above.
11.5 The cost of preparation by King County of the Comprehensive Plan will be
considered a cost of the System and financed out of the rate base.
11.6 The Comprehensive Plans will be “adopted” within the meaning of this
Agreement when the following has occurred:
11.6.a The Comprehensive Plan is approved by the King County Council; and
11.6.b The Comprehensive Plan is approved by cities representing three-quarters
of the population of the incorporated population of jurisdictions that are parties to the Forum
Interlocal Agreement. In calculating the three-quarters, the calculations shall consider only those
incorporated jurisdictions taking formal action to approve or disapprove the Comprehensive Plan
within 120 days of receipt of the Plan. The 120-day time period shall begin to run from receipt
by an incorporated jurisdiction of the Forum's recommendation on the Comprehensive Plan, or,
if the Forum is unable to make a recommendation, upon receipt of the Comprehensive Plan from
the Forum without recommendation.
11.7 Should the Comprehensive Plan be approved by the King County Council, but not
receive approval of three-quarters of the cities acting on the Comprehensive Plan, and should
King County and the cities be unable to resolve their disagreement, then the Comprehensive Plan
shall be referred to the State Department of Ecology and the State Department of Ecology will
resolve any disputes regarding Comprehensive Plan adoption and adequacy by approving or
disapproving the Comprehensive Plan or any part thereof.
11.8 King County shall determine which cities are affected by any proposed
amendment to the Comprehensive Plan. If any City disagrees with such determination, then the
City can request that the Forum determine whether or not the City is affected. Such
Updated April 17, 2019
Att A Page 246
Ordinance 18893
C-252019 Comprehensive Solid Waste Management Plan - July 2018
- 26 -
determination shall be made by a two-thirds majority vote of all representative members of the
Forum.
11.9 Should King County and the affected jurisdictions be unable to agree on
amendments to the Comprehensive Plan, then the proposed amendments shall be referred to the
Department of Ecology to resolve any disputes regarding such amendments.
11.10 Should there be any impasse between the Parties regarding Comprehensive Plan
adoption, adequacy, or consistency or inconsistency or whether any permits or programs adopted
or proposed are consistent with the Comprehensive Plan, then the Department of Ecology shall
resolve said disputes.
XII. MITIGATION
12.1 The County will design, construct and operate Solid Waste facilities in a manner
to mitigate their impact on host Cities and neighboring communities pursuant to applicable law
and regulations.
12.2 The Parties recognize that Solid Waste facilities are regional facilities. The
County further recognizes that host Cities and neighboring communities may sustain impacts
which can include but are not limited to local infrastructure, odor, traffic into and out of Solid
Waste facilities, noise and litter.
12.3 Collaboration in Environmental Review. In the event the County is the sole or co-
Lead Agency, then prior to making a threshold determination under the State Environmental
Policy Act (SEPA), the County will provide a copy of the SEPA environmental checklist, if any,
and proposed SEPA threshold determination to any identifiable Host City (as defined below) and
adjacent or neighboring city that is signatory to the Agreement and that may be affected by the
Updated April 17, 2019
Att A Page 247
Ordinance 18893
C-26 2019 Comprehensive Solid Waste Management Plan - July 2018
- 27 -
project ("Neighboring City") and seek their input. For any facility for which the County prepares
an Environmental Impact Statement (EIS), the County will meet with any identified potential
Host City (as defined below) and any Neighboring City to seek input on the scope of the EIS and
appropriate methodologies and assumptions in preparing the analyses supporting the EIS.
However, nothing in this Section shall limit or impair the County's ability to timely complete the
environmental review process.
12.4 Collaboration in Project Permitting. If a new or reconstructed Solid Waste facility
is proposed to be built within the boundaries of the City ("Host City") and the project requires
one or more "project permits" as defined in chapter 36.70B.020(4) RCW from the Host City,
before submitting its first application for any of the project permits, the County will meet with
the Host City and any Neighboring City, to seek input. However, nothing in this Section shall
limit or impair the County's ability to timely submit applications for or receive permits, nor
waive any permit processing or appeal timelines.
12.5 Separately, the County and the City recognize that in accordance with 36.58.080
RCW, a city is authorized to charge the County to mitigate impacts directly attributable to a
County-owned Solid Waste facility. The County acknowledges that such direct costs include
wear and tear on infrastructure including roads. To the extent that the City establishes that such
charges are reasonably necessary to mitigate such impacts, payments to cover such impacts may
only be expended only to mitigate such impacts and are System costs. If the City believes that it
is entitled to mitigation under this Agreement, the City may request that the County undertake a
technical analysis regarding the extent of impacts authorized for mitigation. Upon receiving such
a request, the County, in coordination with the City and any necessary technical consultants, will
develop any analysis that is reasonable and appropriate to identify impacts. The cost for such
Updated April 17, 2019
Att A Page 248
Ordinance 18893
C-272019 Comprehensive Solid Waste Management Plan - July 2018
- 28 -
analysis is a System cost. The City and County will work cooperatively to determine the
appropriate mitigation payments and will document any agreement in a Memorandum of
Agreement. If the City and the County cannot agree on mitigation payments, the dispute
resolution process under chapter 36.58.080 RCW will apply rather than the dispute resolution
process under Section XII of the Agreement.
XIII. DISPUTE RESOLUTION
13.1 Unless otherwise expressly stated, the terms of this Section XIII shall apply to
disputes arising under this Agreement.
13.2 Initial Meeting.
13.2.a Either Party shall give notice to the other in writing of a dispute involving
this Agreement.
13.2.b Within ten (10) business days of receiving or issuing such notice, the
County shall send an email notice to all Cities.
13.2.c Within ten (10) business days of receiving the County’s notice under
Subsection 13.2.b, a City shall notify the County in writing or email if it wishes to participate in
the Dispute Resolution process.
13.2.d Within not less than twenty-one (21) days nor more than thirty (30) days
of the date of the initial notice of dispute issued under Subsection 13.2.a, the County shall
schedule a time for staff from the County and any City requesting to participate in the dispute
resolution process ("Participating City") to meet (the “initial meeting”). The County shall
endeavor to set such initial meeting a time and place convenient to all Participating Cities and to
the County.

13.3 Executives' Meeting.
13.3.a If the dispute is not resolved within sixty (60) days of the initial meeting,
then within seven (7) days of expiration of the sixty (60)-day period, the County shall send an
email notice to all Participating Cities that the dispute was not resolved and that a meeting of the
County Executive, or his/her designee and the chief executive officer(s) of each Participating
City, or the designees of each Participating City (an “executives' meeting”) shall be scheduled to
attempt to resolve the dispute. It is provided, however, that the County and the Participating
Cities may mutually agree to extend the sixty (60)-day period for an additional fifteen (15) days
if they believe further progress may be made in resolving the dispute, in which case, the
County’s obligation to send its email notice to the Participating Cities under this Subsection that
the dispute was not resolved shall be within seven (7) days of the end of the extension. Likewise,
the County and the Participating Cities may mutually conclude prior to the expiration of the sixty
(60)-day period that further progress is not likely in resolving the dispute at this level, in which
case, the County shall send its email notice that the dispute was not resolved within seven (7)
days of the date that the County and the Participating Cities mutually concluded that further
progress is not likely in resolving the dispute.
13.3.b Within seven (7) days of receiving the County’s notice under Subsection
13.3.a each Participating City shall notify the County in writing or email if it wishes to
participate in the executives' meeting.
13.3.c Within not less than twenty-one (21) days nor more than thirty (30) days
of the date of the notice of the executives' meeting issued under Subsection 13.3.a, the County

under Subsection 13.3.b and to the County.
13.4. Non-Binding Mediation.
13.4.a If the dispute is not resolved within thirty (30) days of the executives'
meeting, then any Participating City that was Party to the executives' meeting or the County may
refer the matter to non-binding meditation by sending written notice within thirty-five (35) days
of the initial executives' meeting to all Parties to such meeting.
13.4.b Within seven (7) days of receiving or issuing notice that a matter will be
referred to non-binding mediation, the County shall send an email notice to all Participating
Cities that provided notice under Subsection 13.3.b informing them of the referral.
13.4.c Within seven (7) days of receiving the County’s notice under Subsection
13.4.b, each Participating City shall notify the County in writing if it wishes to participate in the
non-binding mediation.
13.4.d The mediator will be selected in the following manner: The City(ies)
electing to participate in the mediation shall propose a mediator and the County shall propose a
mediator; in the event the mediators are not the same person, the two mediators shall select a
third mediator who shall mediate the dispute. Alternately, the City(ies) participating in the
mediation and the County may agree to select a mediator through a mediation service mutually
acceptable to the Parties. The Parties to the mediation shall share equally in the costs charged by
the mediator or mediation service. For purposes of allocating costs of the mediator or mediation
service, all Cities participating in the mediation will be considered one Party.
13.5 Superior Court. Any Party, after participating in the non-binding mediation, may
commence an action in King County Superior Court after one hundred eighty (180) days from

the commencement of the mediation, in order to resolve an issue that has not by then been
resolved through non-binding mediation, unless all Parties to the mediation agree to an earlier
date for ending the mediation.
13.6 Unless this Section XIII does not apply to a dispute, then the Parties agree that
they may not seek relief under this Agreement in a court of law or equity unless and until each of
the procedural steps set forth in this Section XIII have been exhausted, provided, that if any
applicable statute of limitations will or may run during the time that may be required to exhaust
the procedural steps in this Section XIII, a Party may file suit to preserve a cause of action while
the Dispute Resolution process continues. The Parties agree that, if necessary and if allowed by
the court, they will seek a stay of any such suit while the Dispute Resolution process is
completed. If the dispute is resolved through the Dispute Resolution process, the Parties agree to
dismiss the lawsuit, including all claims, counterclaims, and cross-claims, with prejudice and
without costs to any Party.
XIV. FORCE MAJEURE
The Parties are not liable for failure to perform pursuant to the terms of this Agreement
when failure to perform was due to an unforeseeable event beyond the control of either Party
(“force majeure”). The term “force majeure” shall include, without limitation by the following
enumeration: acts of nature, acts of civil or military authorities, terrorism, fire, accidents,
shutdowns for purpose of emergency repairs, industrial, civil or public disturbances, or labor
disputes, causing the inability to perform the requirements of this Agreement, if either Party is

inputs. While Normandeau’s WARM inputs are not available, results ranged from 12,000 to 80,000 MTCO2e per year. Their
range is likely explained by a different waste composition assumption, exclusion of bypass waste disposal, and much longer
time periods (and thus larger plants burning more materials) than in this division comparison, which used 2029 as the base
year. The model inputs in the Mass Burn column are the division's assumptions of Normandeau's model inputs.

E-12019 Comprehensive Solid Waste Management Plan - July 2018Responsiveness Summary: Responses to formal comments made during the January 8 – March 8, 2018 public comment period Commenter Public Review Draft Chapter & Page Number Comment Response (Page numbers refer to the 2019 Plan) Federal Way Appendix D-1 Table 1 should have a clearer description of the inputs, and the notes could be more descriptive in declaring why the input variables were used for the 3 disposal methods. For example, for "Moisture" it seems evident why "wet" is selected for Cedar Hills, but not as clear that "national average" is used for Mass Burn, when the WTE plant would presumably be located in King County. EPA has a manual that thoroughly describes the WARM model and its inputs. A reference has been added to tell readers where to find more information. Clyde Hill Chapter 1, pg 1-3 The final plan adoption criteria noted in the first bullet on P. 1-3 requires cities representing ¾ of the total population within the plan to act within 120 days. There are a number of smaller cities represented in this Plan that are marginalized using this sole measure. Please consider adding a second criteria like ¾ of the population and ¾ of the number of cities…not just population. The criteria guiding the Plan’s final adoption are from the Amended and Restated Interlocal Agreements signed by all partner cities. The criteria cannot be changed without amending those agreements. Zero Waste Vashon Chapter 2 - An increase in product stewardship…p. 2-18 this category should also include optimizing/reducing product packaging, including shipping containers. Thank you for your comment. Your suggestion has been added. Zero Waste Vashon Chapter 2 - Expanding collection of Recyclable & Compostable Materials, p. 2-18 & 19 All King county residents and businesses should have access to organics collection service or local compost facilities. In addition, more information should be provided about existing compost facilities and new development alternatives. Chapter 4, Action 24-s and page 4-24 addresses service levels county-wide and on Vashon Island. A discussion of existing composting facilities and developing technologies is found on pages 5-26-28. Zero Waste Vashon Chapter 2 - Figure 2-2, p. 2-4“System Graphic” needs some quantification and additional information, such as a figure caption explaining and quantifying material flows, numbers of private compost facilities, transfer stations, recycling facilities, etc. so the reader better understands the relative magnitudes of the various segments and components. Compost facilities have been added to Figure 2-4. Table 5-5 is also added, including how much material is handled at compost facilities. In addition, tonnage handled at the private MRFs (Table 2-1) and construction and demolition facilities (Tables 4-7 and 4-8) has been added. Zero Waste Vashon Chapter 2 - Figure 2-4. p. 2-9Please include the major compost facilities (such as Cedar Grove) as they fall within this category and do not seem to appear on any other maps. The compost facilities in King County have been added to Figure 2-4. Updated April 17, 2019

Since 2010, SWD has contracted with BioEnergy WA to produce natural gas from Cedar Hills Landfill gas. For more information, see https://www.kingcounty.gov/depts/dnrp/solid-waste/facilities/landfills/landfill-gas.aspx Zero Waste Vashon Chapter 2 - Mitigation, p. 2-24Installing new distributed compost facilities on Vashon Island and elsewhere would greatly reduce vehicle emissions, energy use, and ferry costs required for garbage and yard waste transportation to eastern King County. Thank you for your comment. The mitigation section has been edited. Impact Bioenergy (Srirup Kumar) Chapter 2 - p. 49 (2-24)K4CDecentralized AD and other renewables should be included in "Mitigation" strategies. Information has been added under “Mitigation” for this section on King County’s overarching targets. Impact Bioenergy (Srirup Kumar) Chapter 2 - p.24 Policies There is no mention of resiliency or circular economics of materials. These are components of sustainability too and should be incorporated and prioritized. More information on this topic has been added to the discussion in Chapter 4 regarding a sustainable materials management approach. Impact Bioenergy (Srirup Kumar) Chapter 2 - p.29 ( 2-4) Figure 2-2 Systems Graphic Should include decentralized solutions. A smaller orange loop should be added. An addition has been made to Figure 2-2 to indicate decentralized solutions. Impact Bioenergy (Jan Allen) Chapter 2 - Page 2-18 The heading Expanding the Collection of Recyclable and Compostable Materials should say Expanding the Collection of Recyclable and Degradable Organic Materials. In this section we recommend you add a paragraph that says: There is a convergence of issues around source separated organic waste in King County. These include urban farming, food waste diversion through a variety of technologies, avoidance of synthetic chemicals in horticulture and agriculture, food banks, jobs and resiliency issues around food, smart grids, carbon footprint, climate change, alternative fuel vehicles, and distributed renewable energy. This convergence will continue for the foreseeable future and King County will have to be flexible and innovative to remain in a leadership role since organic waste is such a significant organic fraction in both the waste and recycling streams. Organic waste touches all these issues. Thank you for your suggested edits. Changes have been made to these sections. Updated April 17, 2019

There is a cost to process the materials paid by curbside customers. The companies that process the recyclables benefit from the sales, but it can also lower the cost of recyclables collection. Zero Waste Vashon Chapter 2 - Protecting Natural Resources p. 2-21 Potential new Composting and ReUse facilities should be mentioned here. Thank you for your comment.

Celia Parker Chapter 2 - Representation Need for Rural Area representation on Advisory Committees (it appears from the SWD web site that we are “represented” by KC Council Staff). Who is our representative on KC Council? How does that person know what we want? The Solid Waste Advisory Committee is comprised of residents and representatives from the waste industry, cities, and other businesses. There currently is one representative from the unincorporated area, a vacant agricultural position, and other vacant seats. The Division will be recruiting for vacant seats in the coming months. Zero Waste Vashon Chapter 2 - Revenue Sharing…p. 2-5 Please explain why Vashon Island lacks a certified revenue sharing agreement unlike other WUTC-regulated areas in King County. Waste Connection, the franchise hauler on Vashon, is responsible for initiating a revenue sharing agreement. Zero Waste Vashon Chapter 2 - Sequestration, p. 2-24 Production of biochar by pyrolysis of wood & yard waste would also sequester Carbon for millennial timescales as well as improving soil quality Thank you for your comment. The sequestration section has been edited. Clyde Hill Chapter 2, pg 2-25 Equity and Social Justice This section is critically important as it defines the key principles guiding the operation of the Solid Waste Division. In recent discussions relating to the operation of the Factoria transfer facility (including demand management) and the need for an additional transfer station in the northeast, it was these principles that were crucial in supporting the position of cities in the northeast. The wording in this section needs to be carefully reviewed. It is recommended that two additional bullets be included on page 2-24 as follows: Provide the same level of service to all communities (e.g., estimated travel time to facility, time on site, facility hours, recycling services) Consistent pricing throughout the system.

Woodinville Chapter 3 The City believes that reliable data allows jurisdictions like Woodinville as well as other entities to make well-informed decisions locally and, collectively, for the region. Thus, Woodinville supports the following Comp Plan recommended actions regarding forecasting and data: 1-fd: Standardize the sampling methodology and frequency in tonnage reports submitted to the division and the cities by the collection companies to improve data accuracy 2-fd: Perform solid waste, recycling, organics, and construction and demolition characterization studies at regular intervals to support goal development and tracking 3-fd: Monitor forecast data and update as needed Data collection and forecasting relating to system use and capacity, as well as growth in populations will enable the region to accurately site waste handling facilities in areas where service is lacking. Thank you for your comment and support of the recommended actions.

If a recycling market does not have complete capacity for receipt of asphalt shingles, then demand for that market is lacking. What is King County doing to help develop a market, such as including recycled asphalt shingles in the county’s road paving projects? https://www.kingcounty.gov/depts/dnrp/solid-waste/programs/linkup/shingles.aspx Recycled shingles have been used in several county projects including at the Bow Lake Recycling and Transfer Station and in King County Roads Services projects. Zero Waste Vashon Chapter 3 - Ecology Survey Data p. 3-12 A 3 year lag for data availability seems excessive in this digital age and should be decreased, efforts should be made to acquire timely and comprehensive data relevant to waste & recycling. Thank you for your comment. SWD is dependent on the Washington State Department of Ecology for the data. Zero Waste Vashon Chapter 3 - Figure 3-1, Transfer Station Population forecast 2025-2040 p. 3-3 The bar-graph should include current (2015) values for each area as a baseline. Thank you for your comment. Figure 3-1 is showing projected population numbers by service area that are based on Forecast Analysis Zones. Current population numbers are not available in this format. Zero Waste Vashon Chapter 3 - Figure 3-4, p. 3-5 The bar grab should include several additional time points to illustrate trends (eg, perhaps also 2010, 2006, 2002). Thank you for your comment. Zero Waste Vashon Chapter 3 - Forecasting & Data, p. 3-1 As demonstrated by electricity providers, when consumers have access to their usage data, they are able to reduce usage and optimize peak loads. If consumers were aware of the waste quantities at various local and regional scales, they could potentially modify their behaviors. We need more geo-referenced temporal data. Thank you for your comment. Usage data for solid waste is not as readily available as it is for energy, so would be difficult to implement Zero Waste Vashon Chapter 3 - Multi-Family p. 3-7 & Self Haulers p. 3-9 The disposed volumes are very high yet recycled volumes are disproportionately low for these 2 groups compared with businesses & single family residential, so focused efforts should be made to increase recycling rates among these 2 groups! Need more commitment to education, services, and incentives Although the recycling volumes are low and disposed tons are higher in comparison, the overall tons generated by these two generator types is much smaller when compared to single-family and commercial generators. SWD does have education and outreach for multi-family and some cities choose to provide greater emphasis on multi-family collection. Since the beginning of 2018, SWD has placed a ban on certain recyclable materials being disposed at the transfer stations where recycling opportunities exist.

Federal Way Chapter 3, Figure 3-3 Explain why tonnages increase and decrease around 2029 As depicted, Fig 3-3 shows recycling levels at about 1/4 of what is disposed in 2017, while the text lists 52%. Use a graphic more similar to the one in the earlier draft which "stacked" both types of tonnages, creating a better visual comparison of the total. Figure 3-3 has been updated with the more recent tonnage forecast and corrected to more accurately reflect the garbage and recycling proportions. Federal Way Chapter 3, Figure 3-5 1. Please be consistent in color use (recycling is shownas blue in a prior chart, and blue is often the containercolor associated with recycling).2. This circle graph makes it appear that the blue areais larger than the green area. (53% v. 47%)3. The category "other materials" shows 0% recycling,so please make changes as suggested by this comment.Recycling events collect "other materials" like wood,electronics, batteries, textiles, even bicycles. Presumably,these materials may be outside what was measured incoming up with these percentages (or may be less than0.5% of total diversion, and so effectively 0%). But the figuresays 0% of other SF materials are diverted to recycling.Perhaps say <l% and use "-" instead of "O" for the tonsrecycled. Presumably, these charts focus on MSW that thesystem is designed to handle, so options like reuse ordonation are not counted.Figure 3-5 note 'a': The term 'recycled' is out of place.

For example, the closure of some of China's recycling import markets and the possible increased light weighting of packaging may drive significant changes in the region's disposal needs. Requested change (p 3-1 to 3-4): Expand the Forecasting section to describe how the forecast does or does not consider potential substantial changes in waste stream characteristics and/or major disruptions in recycling markets. Clyde Hill Chapter 3, pgs 3-1 through 3-4 Note that the forecasting of tonnage of waste disposed in the landfill is done in two steps (see top two paragraphs on page 3-6). In the first step, a baseline forecast is completed which assumes the percentage of waste recycled remains constant (57%). In the second step, the baseline is adjusted to exclude material diverted from disposal as a result of additional recycling. It is not clear in the Comprehensive Plan whether any of the projections that are included were prepared using the second step. It would be helpful if each projection clearly stated which technique was used in its preparation. Given (1) the recycling rate has been difficult to forecast and (2) the sensitivity of tonnage forecasts and related life of the Cedar Hills Landfill, it is very important that readers understand the recycling rate assumptions used in each projection. Thank you for your comment. The Forecasting section has been edited to describe the forecasting inputs and process to the forecast more clearly. Greater Maple Valley UAC Chapter 3, Policies FD-1, FD-2, FD-3, and Action3-fd Such information should be made available to the Public for education purposes and to further the goals of the Plan.

Or coordinate with local schools to allow use of their recycle bins? Create bins where broken down boxes can be inserted but the container always has lid over too so rain doesn’t ruin cardboard if someone leaves lid open. Impact Bioenergy (Srirup Kumar) Chapter 4 Chapter 70.95.N RCW which requires manufacturers of the covered electronic products (TVs, computers, monitors, and portable DVD players) to provide collection services in every county, city, or town with a population greater than 10,000. There are no sites or collections services on Vashon, where the population is now 12,000+. Thank you for your comment. The Washington Materials Management and Financing Authority is tasked with implementing the state law with oversight from the Department of Ecology. The law does not require there to be a collection site on Vashon Island because it is a part of unincorporated King County, and collection sites are available throughout the county. For more information, see http://wmmfa.net/ Clyde Hill Chapter 4 Operation Green Fence - How does China’s decision to ban the import of 24 varieties of solid waste and recyclables (Operation Green Fence) impact the ideas and goals within this Chapter? The Plan is written to be flexible, giving the County and cities the structure to provide collection and outreach programs, but also the ability to adjust to changing conditions. Covington Chapter 4 Chapter 4 mentions the potential to phase out the recycling grants to cities program as enhanced recycling services are added to renovated transfer facilities. Although we support the need to improve services at the transfer facilities, we feel it is important to continue with these recycling grant programs with local cities. The elimination of these programs will result in a reduced level of service and an increase in illegal dumping of these types of materials. The Plan does not contemplate phasing out grants to cities. The Plan mentions that there may be alternative ways for cities to provide for special recycling collection events. Bothell provides vouchers to their residents to recycle materials at the Shoreline Recycling & Transfer Station, instead of holding recycling collection events. King County mails vouchers to White Center residents to recycle at the Bow Lake RTS instead of holding recycling collection events in that community.

However, we believe that the region cannot collectively achieve any of these goals without an unwavering commitment on the part of all cities to implement most if not all of the recommended tools such as mandatory garbage collection and recycling. If all cities do not implement all the actions, only incremental improvements will occur. It is important that the Plan also explicitly express the gravity of indecision and inaction. the recommended tools and strategies discussed in the plan. Kirkland Chapter 4 We recognize that implementing the variety of actions in the Plan can be expensive and we encourage the County to continue to provide and even increase grant funding and technical assistance to all city members of the system to help us achieve our waste prevention and recycling goals. Thank you for your comment. Actions 2-s, 12-s, and 13-s are examples of actions that the division and the cities can work together on to improve the grant program. Maple Valley Chapter 4 The City of Maple Valley recommends that King County continue to allow cities to use King County grant funds for recycling collection events and not phase out collection events as an option. The public relies on these events to recycle materials not collected curbside or at transfer stations. Phasing out the recycling events would be perceived by the public as a reduction in City services, and could lead to increased illegal dumping. Thank you for your comment. The county would not change the grant guidelines that currently allow cities to spend those funds on recycling collection events without first consulting with the cities. Maple Valley Chapter 4 We encourage the development of a new grant program to support cities and other stakeholder help meet waste reduction and recycle goals identified in the plan. Thank you for your support of a new grant program. Redmond Chapter 4 Redmond supports the goal to divert 70% of garbage through recycling. As the region implements the Growth Management Act (GMA), we are seeing a significant increase in multifamily construction. This aligns with the GMA vision to accommodate more people and jobs through higher densities in cities and limiting sprawl. In light of this planned increase in multifamily housing, we urge the County to work with cities on actions that Thank you for your comment. Improving multi-family recycling is an important part of achieving our goals. King County, working with the haulers, has developed multi-family recycling best practices.

The EIS states that increased recycling may result in a net increase in truck trips and affect specific transportation routes (EIS at 1-1, 1-2, 1-3). As the rate of recycling increases, Woodinville will experience additional impacts related to increased tonnage and traffic to the Cascade Recycling Center. Nevertheless, Woodinville recognizes that increased recycling is better for the region because it represents a more sustainable approach to materials management. With respect to the various EIS alternatives for achieving increased recycling, Woodinville is open to adopting practical and effective regulations in coordination with county efforts but while minimizing increases in administrative costs where possible (see EIS at 1-1, 1-2, 1-3). Thank you for your comment. This comment is also addressed in the responsiveness summary for the EIS. Celia Parker Chapter 4 On the Plan Chapter 4 Summary of Recommended Actions 3-s and 28-s Among parties to educate, can we consider manufacturers? Would/could there be an effort to work with manufacturers to reduce wasteful packaging? E.G. At a health food store I bought bags of tea in a ~7 inch tall plastic barrel. At the time I had to drive 10 miles to Fairwood to recycle the plastic. I looked up and emailed the company that sold the tea and gave a packaging suggestion. They revised their packaging to a paper-like sealable bag that could be easily thrown away. Thank you for your comment. SWD does encourage manufacturers through the LINKUP program to use recyclable materials as feedstocks. SWD also participates on the NW Product Stewardship Council to work at a regional level to implement programs where manufacturers take responsibility for the products that they produce.

Consider banning plastic bags in King County. Need more commitment to education and research and development. Solutions are out there. KCSW needs to process and implement these solutions, therefore we need to make this plan more dynamic and provide the ability to both R&D, educate, and pilot. Need novel education paths, including promotion of short educational films about how things are sorted at our sorting stations, how/what to compost, and a general knowledge of plastics and the waste stream. Thank you for your comment. Waste Management Chapter 4 – Action 4-S WMW supports the exploration of a product stewardship strategy and concepts for the management of toxic materials or materials that can be difficult to manage. However, we do not advocate product stewardship or extended producer responsibility (EPR) for traditional recyclables such as paper and packaging for the following reasons that we hope that King County will adequately consider. EPR for paper and packaging focuses solely on the end-of-life management of materials, rather than considering the full lifecycle impacts of materials, along their entire life. Producer focus will be on end-of-life recycling of their products, instead of reducing energy and greenhouse gas outputs and impacts along the lifecycle of the product, especially in upstream design and production of the materials. Thus, EPR for paper and packaging will make it impossible to change the focus on achieving broader environmental goals such as reducing carbon footprints. Thank you for your comment. You raise many important issues that warrant further discussion as we move forward with implementing the Plan. There will be ample opportunity to discuss these issues both with our advisory committees and other venues. Updated April 17, 2019

E-12 2019 Comprehensive Solid Waste Management Plan - July 2018Responsiveness Summary: Responses to formal comments made during the January 8 – March 8, 2018 public comment period Commenter Public Review Draft Chapter & Page Number Comment Response (Page numbers refer to the 2019 Plan) There is no evidence that EPR increases recycling. Successful, sustainable recycling programs are the result of comprehensive and sweeping local solid waste policies and programs, such as those offered by King County in this Plan that achieve high diversion rates. These developed and thoughtful solid waste policies help drive consumer behavioral changes by crafting successful recycling programs that focus on social behavior changes and creating the right local incentives. That is, solid waste policies are needed to drive recycling programs, not money from producers and manufacturers. Our current system is built around local communities and accountability. Local officials hear from their neighbors and constituents when something is not working. That relationship link between local government and communities will be broken with an EPR system for paper and packaging. Producers will control the programs, creating uniform statewide service offerings. There will be no role for local ordinances. Many local communities have created rates, bans and incentives to drive successful recycling programs. These ordinances can reflect shared local values, environmental ethos, and respect differences in geography, population density, ecosystem vulnerability and economics. With manufacturers running a uniform statewide program, local governments have few incentives to innovate with education programs, variable fees, or innovative service options. Finally, EPR for packaging and paper is focused on driving to the lowest cost as the primary goal. Consequently, producers are unlikely to pursue high performance programs and value assets that are important to local Updated April 17, 2019

EPR fees are also regressive with the increased costs and fees associated with EPR born disproportionately by low-income households who spend a higher portion of their income on packaging than on durable goods. Waste Management Chapter 4 - Action 14-S Regional capacity for recycling of materials is not developed via education and enforcement of disposal bans, but, rather creating and offering incentives will build capacity. WMW encourages King County to generate incentives to promote investment in construction and demolition debris facilities and diversion of these materials from the waste stream. As a result, self-regulating industry enforcement would also evolve in developing and shaping the market demand for these materials. Thank you for your comment. Recommended Action 14-s has been edited to reflect your comments(removed the word “capacity”). Further discussionof possible incentives could occur at a futureconstruction and demolition materials stakeholders’meeting.Waste Management Chapter 4 - Action 26-S WMW recommends adding an additional action item to monitor recycling markets, at the very least on an annual basis, especially with market disruption factors in play such as China’s National Sword policy. We certainly support establishing a formal process, and related criteria, to remove materials from the designated recyclables list as market conditions may require. Currently, there is an informal process to eliminate items from the list, which generally involves asking processors if the facility currently accepts a material stream. As previously stated, we believe more formal procedures are needed here. Thank you for your comment. Policy FD-3 supports monitoring recycling markets. Further discussion with stakeholders is needed to determine the scope of this work.

Page 4-28 discusses single-family residential minimum collection standards and states on the following page that “Based on this evaluation, it is recommended that minimum collection standards be adopted by the cities and unincorporated areas to provide the optimal service level for reducing waste and increasing the diversion of recyclables and organics from disposal.” The chart suggests garbage collection to be a “minimum of once a month.” Given the proviso response indicating that the Division is not going to pursue reduced garbage collection in the unincorporated areas, can you help us understand the choice to link 29-s to that particular discussion and not a broader discussion of ways to increase recycling in the unincorporated areas? We will review which page should be referenced for explaining approaches to improving unincorporated single-family collection. The minimum standards table shows the lowest level of service that a jurisdiction in the regional system can choose. It does not obligate a jurisdiction to choose the lowest level. The garbage minimum is monthly because some cities offer once a month garbage pick-up in some circumstances and the plan acknowledges that level of service. However, most jurisdictions have weekly garbage pick-up. Because weekly pick-up is a higher level of service than the monthly minimum, it also is a service choice allowed by the plan. The plan does not include a change in garbage pick-up frequency in the unincorporated area. Sharon Eno Chapter 4 - Composting Currently, in Shoreline there is no compost program that is required. There is so much food waste that should be composted. People are totally illiterate about the need for this and how to do it. Making composting mandatory should be a part of any smart waste disposal program. Please consider making this mandatory. Thank you for your comment. Although it has been discussed many times, the county and the cities have not been able to reach agreement about making garbage, recycling, and/or organics collection mandatory. The City of Shoreline does offer curbside yard/food waste collection services and could institute mandatory programs if residents wanted it. Ann Siems Chapter 4 - Education Also educate via advertising of all kind. People think, oh it’s just a paper cup, I am so good, I will recycle it. They have no idea how much pollution is created via the paper industry, the difficulty of recycling such cups and the lids, not to mention the stupid straws. Make waste HURT.

Thank you for your comment Cedar Grove Chapter 4 - Organics collection Cedar Grove suggests the County strongly consider no longer providing exemptions to the requirement of weekly curbside collection of organics. These exemptions, allowing bi-weekly residential collection, do not support County stated goals for managing garbage and recycling for the next 20 years. A firm commitment to weekly collection of organics will increase diversion from the landfill and help the County reach its 70 percent goal. This is a simple but effective way to increase participation in recycling County-wide. County studies show that one of the primary barriers to public participation in organics programs is the fear, real or perceived, of recycling food scraps. And the allowance of bi-weekly collection of organics serves as a deterrent to The County does not issue exemptions. The Health Department establishes minimum frequencies of garbage and organics collection. In developing this draft Plan, the advisory committees identified the minimum standards for organics collection to be at least every other week, as allowed by the Health Department. This does not prevent cities from having more frequent, weekly collection. The County may consider changes to collection frequencies in the unincorporated areas in the future. Updated April 17, 2019

In the County’s 2008 study, “Overcoming the Ick Factor: Increasing Participation in Food Scrap Recycling in King County, WA”, weekly collection was identified as a change that would positively impact participation by 71% of respondents. Additionally, weekly collection will ensure that transfer and processing facilities receive fresh and less odiferous material that otherwise could have spent many weeks decomposing in bins. The weekly flow of material, therefore, will mitigate community impacts. County resident perceptions and behaviors have evolved significantly over the past 10 years towards a commitment to keeping valuable natural resources out of the landfill and into productive use. Weekly collection is a proven way to influence those who are not participating in organics recycling to do so. It will also likely increase the participation of those already committed to the program through increased opportunities. Moreover, for the ratepayer, standardizing collection frequency would bring service equity across the cities within the County, and increased diversion will provide desired flexibility regarding decisions for disposal of garbage over the long term. Zero Waste Vashon Chapter 4 - Organics p 4-4More commitment to organics processing and products/marketing! On a societal level and with King County Solid Waste as the driver we should make a societal commitment to go organic whenever possible. Packaging, ink dies, plastics, paper products are examples of what should be diverted from waste to resource. King County organics processing is now operating at maximum capacity. Up to 30% of our waste stream is still organic based. Thank you for your comment. Support for organics processing and products/markets will continue to be a focus in our efforts to achieve higher recycling levels. This is reflected in Policies S-5, S-7, S-8 and Recommended Actions 24-s, 28-s, 33-s. Updated April 17, 2019

We should be able to divert ½ of this from waste to resource thereby increasing our recycle rate 10% across the board! By doing this we increase the life span of Cedar Hills landfill, through environmental economics drive markets towards more organics use, and get us ½ of the way to our goal of 70% recycle rate! Therefore: we need the ability to better sort at the individual, hauler, and community level, and we need more compost facilities ideally spread throughout the county.

Waste Management Chapter 4 - Page 4-5, Waste Prevention and Recycling Goal and Targets Although King County addresses sustainable materials management later in this same chapter, the County could be a leader in this arena by fully embracing sustainable materials management (SMM) principles and begin a departure from solely evaluating recycling goals based on weight, such as the County’s interim goal of achieving 70% recycling. SMM represents a paradigm shift in how we look at and manage materials by reducing environmental impacts throughout all stages of a product’s life cycle, as these materials move through the economy, from resource extraction to end of life management. SMM’s emphasis is on protecting human health and the environment by advancing the sustainable use of materials throughout their lifecycle to minimize waste and environmental impacts, including reductions in greenhouse gas emissions and in water and energy use. Solid waste policies should encourage true recycling and not “diversion for diversion’s sake.” The best way to embrace SMM is to adopt Life Cycle thinking and analysis, in which each material is evaluated at a broader level to determine its optimal disposition. Instead of measuring success based on a percentage recycled, success should be awarded for greenhouse gas emissions reduced, for example. In using traditional weight-based recovery or recycling rates, recovery of materials is treated the same: A ton is a ton is a ton and all recovery is treated the same (recycling = composting = “counting” energy recovery). Accepting only weight-based recycling goals does not appropriately address or value the solid waste hierarchy. In particular, little Thank you for your comment. Although this Plan includes a 70% interim recycling goal, it also includes other targets that help to assess waste reduction (per capita and per employee waste disposed and waste generated targets). In addition, Action 20-s identifies the need to develop a target for reducing greenhouse gas emissions from disposed waste. The 70% goal remains in the Plan because the majority of the advisory committee members wished to keep it. Updated April 17, 2019

However, SMM compares the environmental outcomes of waste management, focuses on the full life cycle, not only end-of-life management, and ultimately supports more and better recycling and waste prevention. Ann Siems Chapter 4 - Product Stewardship People start to change behavior when it costs money. It is time that we ask fees for all the garbage that is produced via throw away containers, charge for coffee cups to go, charge more for people who don’t recycle properly etc. Thank you for your comment. Debbie Shapiro Chapter 4 - Recycling I'd love for recycling to be weekly, rather than bi-weekly. We wind up with an overfull can and have left over that we have to hold for the next 2 weeks. Thank you for your comment. You can request an additional recycling cart or set out additional materials as allowed by your local hauling company. Republic Services Chapter 4 - Recycling King County has a goal to recycle 70 percent of our waste stream, an increase from 52% today. What sorts of ideas do you have to help us reach this ambitious goal? The goal to recycle 70 percent of the waste stream is built using flawed data*. Consider a goal that asks cities to reduce the amount of waste going to the landfill (isn’t that the desired outcome?) For example, if the average pounds per household is 26 pounds in Kent or 23 pounds in Bellevue, cities could be asked to campaign their citizens to reduce one pound per household per week. *King County uses tonnage data (total amount at the curb minus the weight of recycling and organics). This premise is flawed because 1. Recycling is becoming lighter and lighter (it used to take 40,000 empty water bottles to make a ton; today it takes 90,000). 2. There are third-party recyclers who do not report their data to the county or state 3. There are third-party landscapers (for homes and commercial properties) who do not report their tonnage data to the county or state. Thank you for your comment. Although this Plan includes a 70% interim recycling goal, it also includes other targets that help to assess waste reduction (per capita and per employee waste disposed and waste generated targets). In addition, Action 20-s identifies the need to develop a target for reducing greenhouse gas emissions from disposed waste.

The ONLY number that can be counted on reliably is the tonnage going to the landfill. THAT is the number that should inform the goal. Auburn Chapter 4 - Recycling The City of Auburn would like to thank the SWD for its continued guidance and support to assist cities as we work to reach our waste reduction and recycling goals. The efforts to enhance recycling opportunities and increase product stewardship are invaluable. We look forward to continuing working together to keep solid waste rates as low as possible by reducing, reusing, and recycling. Thank you for your comment Carnation Chapter 4 - Recycling As City Manager of the City of Carnation, I want to say thank you for working to update the Comprehensive Solid Waste Management Plan. Effective management of Solid Waste is critical and it is important to be forward thinking and progressive when making decisions on the future of this function. I believe King County is taking the right steps in developing a great plan by accepting public comment. As King County moves forward with these services, it is essential for the future of King County to continue its commitment to recycling. To reach our goal to recycle 70 percent of our waste stream, we must continue to educate the public on the benefits and best methods for recycling. When in doubt, residents will most likely deposit the item into the waste stream. This education effort must be combined with a commitment from local government to make certain recyclables are recycled. The recycling market is ever changing and nothing discourages residents from recycling more than knowing the final destination for these items is a landfill. Thank you for your comment. Jim Loring Chapter 4 - Recycling Recycle as much as is economically feasible and be willing to accept this may well fall short of some arbitrary 70% goal. Thank you for your comment.

Disposal of products when recycling life has ended. Increasing uses and markets for recyclables Thank you for your comment.

I live in Snohomish County but work in Woodinville, in King County. I was reading the Woodinville Weekly the other day and there was an article titled "Council gets the lowdown on waste". In it you had explained that "70% of what goes to the landfill doesn't belong there" and that "sorting doesn't always work". Then you say initiatives will be more achievable by encouraging manufacturers to use more sustainable materials. The article goes on to say that the three major options that are being contemplated are building a new facility, developing the existing facility at Cedar Hills, or exporting the waste by rail to an out-of-county landfill. What I'm writing you to say is that while I think using sustainable materials is a step in the right direction, I think there should be a bigger push to consume less altogether. We as a society have become complacent when it comes to how much we consume. It has become too easy to buy something that will become useless within a few months, then throw it away. There isn't any accountability when we are able to throw something away and maintain an "out of sight, out of mind" mentality.

That cool 90's Troll doll that everyone had? Sure, hop on Amazon, order one that is most definitely made in China, shipped to the U.S. on container ships whose exhaust and waste are mostly unregulated, so Amazon can put it in a cardboard box with plastic bubble wrapping with shipping labels and adhesive tape, then someone can drive it to your doorstep where you can scratch that nostalgia itch for a few weeks. Then all of it goes in the trash. Kind of a long example but I wanted to paint the picture of how much needless waste is created. So while I think sustainable materials and proper education of how to dispose of our waste is a great idea, I think the more beneficial idea is to move away from consuming so much needless things. The need for a new waste facility or developing the existing facility or shipping the waste to a different facility are all inevitable, but perhaps we can delay the need for them by shifting away from a consumerist society. And let's face it, manufacturers are only going to shift to a sustainable packaging if it's cost effective to do so. But like you had mentioned, what we can do is educate the public on how to appropriately separate their waste and which facilities to bring which materials to (I have to lie and say I am a Bothell resident to recycle styrofoam at the Recology store in Canyon Park. Sorry.) Maybe we can couple this education with some sort of anti-waste agenda, because after all, recycling requires the creation of waste.

Impact Bioenergy (Jan Allen) Chapter 4 Sustainable Materials Management: In this section we recommend you add the following text: King County has an opportunity to offer innovation partnerships with the private sector by offering planning assistance, coordination with transfer stations, public education, and grant support for innovative demonstration projects that focus on the county’s priorities. For example, community-scale anaerobic digestion represents an opportunity to manage organic waste onsite, or in community neighborhoods by converting that waste into both renewable energy and liquid soil amendment with zero waste with a high level of vector and odor control. The amendment has nutrients, water, organic matter and probiotics for supporting healthy chemical free soil and food production. Rarely does an opportunity come along that can touch on energy, water, air, soil, food, jobs, and education simultaneously. This one does. Thank you for your suggested edits. Changes have been made to the discussion on anaerobic digestion in Chapter 5. Greater Maple Valley UAC Chapter 4, Goal We support this goal and the highest priority: a. Waste prevention and reuse. Thank you for your comment. Bothell Chapter 4, pg 4-22 We are requesting you edit Pages 4-22 to include Waste Management as the second solid waste hauler in the City of Bothell. The "f' notation is correct noting we switched haulers with a contract in 2015. Due to recent annexations, Waste Management is still providing collection services in portions of Bothell necessitating the need to add them to the list. The requested edits have been made.

While constructing a new NERTS is the most capital intensive of the three transfer options in the Plan, it is clearly the most equitable, efficient, and environmentally responsible alternative that would provide a level of service to the residents and businesses in the northeast County equal to the levels of service provided in other parts of the County. As such, we strongly support the option to site and build a new NERTS and would welcome the opportunity to participate in a siting process with our fellow municipal and County stakeholders. Kirkland would welcome the opportunity to be considered as the host city for a properly mitigated new NERTS and participate in an open and transparent public engagement siting process that includes collaboration with the County and stakeholders on the development of a set of siting criteria that recognize the specific and unique needs of cities and their constituents living and working in the northeast County. Kirkland Chapter 5 We would like to suggest the Plan recognize, and demonstrate with a map, the cities that host private solid waste and recycling facilities, such as the Waste Management Cascade Recycling Center in Woodinville or the Republic Services transfer station in Renton. Private transfer and processing facilities, while not identified as essential, are critical to the overall operation of the solid waste transfer system, but also have traffic, litter, noise, and odor impacts similar to King County’s public facilities – negative aspects and costs that are often unrecognized, but are nonetheless borne, by host cities.

Transfer Station. The Houghton Transfer Station would be closed once the new station opens. Newcastle Chapter 5 The City has particular concerns over the planned closure of the Renton Station and the potential closing and/or replacement of the Houghton Station. With these closures, Factoria becomes the practical and designated station for Newcastle; however, the Plan does not recognize Newcastle as being part of the Northeast Service Area. Newcastle should be formally added to the Northeast Service Area and be planned for accordingly. Newcastle’s concern over service availability if the Renton and Houghton stations close is noted. Newcastle’s needs will be part of Northeast transfer capacity planning and stakeholder involvement Newcastle Chapter 5 The new Factoria Transfer station has better facilities than Renton Transfer Station, which will attract more traffic to the already overburdened Factoria/Coal Creek/I‐405 interchange area. In addition, when the Renton Station closes all of Newcastle’s haulers, along with other areas of north Renton and the southeast, will be redirected to the Factoria Transfer Station. This is particularly concerning to Newcastle because as bad as it is on I‐405, most haulers in our area will choose Coal Creek Parkway as the alternative route to and from Factoria. While Newcastle has designated Coal Creek Parkway a principle arterial intended to connect larger communities, it was not anticipated the road would be used for heavy commercial vehicles. We are therefore concerned over the impact that increased use of Coal Creek Parkway by commercial haulers will have on its pavement life. When KCSW evaluated traffic at the Factoria Station, it only looked at backups on Richards Road caused by long wait lines to the station. It did not look at the additional traffic burdens on Factoria Boulevard going to I‐405 (passing through a main commercial/residential area with a high school and churches). This is the main route for all KCSW trucks going to/from the station. Moreover, it is the main The decision about whether to keep Renton open or to close it has not yet been made.

In addition, Woodinville acknowledges the need for balancing several important factors related to solid waste—such as maintaining reasonable fees for customers, protecting natural resources through environmental stewardship, and promoting system equity. In this regard, Woodinville supports a solid waste system that provides convenient access for all customers in the service area without becoming a disproportionate burden on any particular community. To date, Woodinville has managed to balance existing waste handling with community needs, such as limiting vehicular traffic, and maintaining Woodinville’s beautiful natural open spaces.

Woodinville Chapter 5 Turning next to the Comp Plan’s recommended actions on the transfer of solid waste, Woodinville is particularly interested in action 1‐t as it applies to planning for adequate transfer capacity in the Northeast service area. Woodinville understands that demand management strategies cannot substitute for a transfer station in the Northeast service area because certain circumstances, such as Bellevue’s participation in the system, have changed since that option was first evaluated. With respect to the remaining three options for providing transfer capacity, Woodinville requests to be involved in the decision‐making process. As Woodinville understands them, the three options include: (1) continuing operations at the Houghton Transfer Station (which corresponds with “Alternative 1” Solid Waste Transfer and Processing System Facility Improvements in the EIS at 1‐5); (2)building a new transfer station in the Northeast servicearea; and (3) building several smaller transfer sites in theNortheast service area (these last two options appear to bedifferent variations of “Alternative 3” in the EIS at 1‐7).The Comp Plan states that “an advisory committee composed of Northeast service area residents, city, and business representatives would be formed to develop siting criteria that would guide the site selection process,” a practice that the Comp Plan indicates is consistent with King County’s Solid Waste Facility Siting Plan (hereinafter “the Siting Plan”) (Comp Plan at 5‐19). The Siting Plan states that “[c]itizen advisory committees shall be used to reflect the values of host communities as an effective means of weighting criteria” (Siting Plan at C‐17). Based on the Comp Plan, the Northeast service area A process to involve cities and other stakeholders in the siting process will be developed in consultation with northeast cities. One on one discussions between the division and potentially affected cities also will be part of the project scoping and decision making process.

One point on which Woodinville seeks clarification is whether the list of Northeast service area municipalities in the Comp Plan is exhaustive and whether all of those entities will be represented in the decision-making process via the advisory committee or some other vehicle. As noted earlier, Woodinville requests to be a part of the siting process and is committed to remaining engaged throughout the decision-making process. Woodinville Chapter 5 Another point on which Woodinville would appreciate clarification is the data underlying Table 5-4 (Comp Plan at 5-20). Although the percentage of a jurisdiction’s transactions through Houghton Transfer Station is relevant to understanding use of that station, Woodinville would like to obtain the data on the actual tonnage and number of truck trips generated by each jurisdiction’s use of Houghton. Moreover, Table 5-4 does not list all of the jurisdictions provided for in the Comp Plan as comprising the Northeast service area; transactions from Kenmore, Bellevue, and unincorporated King County are not listed (Comp Plan at 5-20). Table 5-4 was removed from the Plan. Woodinville Chapter 5 According to the Comp Plan, transfer capacity in the Northeast area will be “allocated equitably among jurisdictions” (Comp Plan at 5-21). Those transfer station site options that are geographically distant from existing waste handling and disposal facilities should be preferred over those site options that are in close proximity to existing facilities (see Siting Plan at C-15, C-16). And, relatedly, Woodinville’s support of the Cascade Recycling Center, the Brightwater Wastewater Treatment Plant, and the DTG Recycling Group should be taken into consideration.

The current EIS draft associated with the Comp Plan does not yet address the specific impacts of Northeast sites because no sites have yet been identified. Woodinville seeks to be an active participant in the site identification and screening process if the County goes forward with either of the two alternatives involving the construction of new facilities in the Northeast. Based upon the analysis completed in the EIS, the best alternative may be to continue use of the Houghton transfer station, and along those lines, ensure full utilization of all existing and possibly underutilized transfer stations to avoid the need to construct new facilities. Creating a new Northeast transfer station would result in a loss of vegetation and wildlife habitat, would produce CO2 emissions from construction and operation, would impact noise and transportation during construction, and involve high capital costs (EIS at 1-7 to 1-10). Additionally, maintaining Houghton is the lowest cost option in terms of capital and operating costs (Comp Plan 5-22). Regardless of which alternative the county pursues, Woodinville seeks to provide ongoing input because appropriate mitigation of impacts on cities is important to regional equity.

We are focusing our comments on the air quality impacts of the current and proposed alternatives for operations by King County Solid Waste Division (KCSWD) and its contractors. Specifically, we are interested that the air impacts related to organics processing and recycling (also referred to as "composting" in this letter) be adequately identified and considered. The Draft SWMP and DEIS discuss the current level of organics recycling, estimated at 52% in 2014 and identify various alternatives that would increase that to a goal of 70%. The air quality analysis in the DEIS discusses a variety of general air quality issues on this topic, but does not clearly acknowledge (or discuss) the existing odor impact conditions in communities with composting operations. The summary for Alternative I (No Action) states the impact of this choice would be increased greenhouse gas emissions and higher disposal costs, both as a result of not increasing the recycling rate. It also states that the existing organics recycling capacity is unknown, but that increasing to a rate of 70% will require more facilities and/or capacity. As the primary recipient of odor complaints for King, Kitsap, Pierce and Snohomish Counties, our agency has a comprehensive understanding of the impacts current composting operations have on surrounding communities, and they are significant. In 2017, the Agency received approximately 4,010 complaints related to odor. Of those, approximately 2,500 were directly related to the composting facility in Maple Valley. Over the past 10 years, nearly half of all odor complaints received were related to the Maple Valley facility, and more odor Thank you for your comment.

Puget Sound Clean Air Agency Chapter 5 - Composting/ Air quality Based on the feedback we receive from the public, we believe that these existing conditions have not been adequately identified or evaluated in the DEIS and will be an impediment to additional recycling because communities will not have the confidence that impacts will be properly mitigated . On page 5-30 of the Draft SWMP, the County speaks to these issues indirectly. Specifically, it states: More capacity will be needed to recycle more as the existing facilities may be near their maximum permitted capacities (p. 5-30, ¶2) Regional composting facilities were designed for yard waste, not the mix of food, yard and compostable packaging that is collected and processed today. There exists a need for upgraded technology to manage the new material mix (p. 5-30, ¶2, 2nd bullet) Financing for technology upgrades at existing facilities (p. 5-30, ¶4, 4th bullet) Some of these observations were identified as needed to maintain the quality of the finished product. We do not have specific information to comment on the existing capacity in the market for organics recycling, but it is likely that the existing facilities are at or beyond their capacity, especially when you consider the short-term processing rates they can manage. The throughput at these facilities varies seasonally for reasons beyond their control. The comment above regarding the original design for yard waste is apt. Recent research has indicated that increasing the food waste portion to 15% of the total waste stream (food and yard waste combined) can double the organic emission rate from composting operations, meaning that more food recycled leads to more organic emissions which contributes The Plan and EIS text have been revised to include a discussion of existing odor impacts in communities containing commercial-scale composting operations, and to discuss the potential for increased odor impacts as a result of increased recycling and subsequent composting of organics.

Revise the Summary (Chapter 1.2/Tables S) and Chapters 3-5 to include: a description and discussion of existing conditions (in 2017-2018) in communities surrounding composting facilities in the County (and facilities used by the County for organics recycling), and identification of odor impacts caused by existing conditions so that all alternatives and impacts can be evaluated adequately against existing conditions. 2. Revise all subsequent discussions of alternatives and impacts in the Summary (Chapter 1.2/Tables S) and Chapters 3-5 to account for, as needed, the updated description and discussion of existing conditions per item (1) above. 3. Revise Chapters 3-5 to identify and evaluate odor impacts from the proposed increased rates and types of recycling for each alternative (and revise the conclusions reached related to such impacts in 3.2.2.3, 4.2 .2.3, 4.4.2.3 and 5.2.2.3 as needed). 4. Revise Chapters 3-5 to include and evaluate specific, reasonable mitigation measures for the odor impacts to be caused by each alternative and describe the mitigation measures that the County is willing to commit to implement to address the odor impacts that will be experienced in the communities for each alternative. The Draft SWMP should then be revised accordingly based upon the revised information and analyses included in the revised DEIS. The Plan and EIS text have been revised to include expanded discussions of odor impacts associated with existing commercial-scale composting facilities, potential odor impacts resulting from increased organics recycling and composting, and measures to mitigate potential odor impacts.

The Draft SWMP and DEIS do not identify what future mitigation may be appropriate for future composting facilities or expanded capacities at existing composting facilities. While some specific mitigation will also be considered in future review of specific proposals, as requested above in (4), the County should now identify in the Draft SWMP and DEIS reasonable mitigation measures for odor impacts and what mitigation the County is willing to commit to implement to address the odor impacts that will be experienced in the communities for each alternative it is considering. The Plan and EIS text have been revised to include specific measures that could be implemented to mitigate potential odor impacts resulting from composting of recycled organics. Puget Sound Clean Air Agency Chapter 5 - Composting/ Air quality The Draft SWMP plan also indicates in order to expand organics recycling, "....a regional dialogue with exploration of alternatives and solutions for expanding capacity is necessary. This will help minimize environmental and community impacts related to regional organics process and ensure an adequate capacity and infrastructure is in place for regional organics processing, including contingency plans in the event regional capacity is constrained."

Olympic Environmental Resources provides management of residential recycling collection events for many cities in King County. Residential recycling collection events have been successful at working towards King County's goals of reducing waste and recycling. The events have been a stable and consistent service that has removed many millions of pounds of material from the waste stream and served hundreds of thousands of King County residents. In the nearly three decades that events have been in place, residential recycling collection events continue to accomplish the following: Been a stable and consistent service that has removed millions of pounds of material from the King County waste stream which can be easily tracked for program results. Providing for the collection of hard to recycle items. Provide a successful opportunity for King County and county cities to work together towards a common goal. Reduce the instance of illegal dumping, particularly in rural areas of King County. Provide an opportunity to recycle bulky items that would likely end up at transfer stations, thus reducing transfer station "self-haul" traffic. Used in King County cities as a way to clean up unsightly residential locations by providing a location for residents to dispose of those items. In bad commodities markets (like the current state of scrap metal and used oil), recycling collection events have filled a needed service where the private sector has reduced or eliminated service.

Woodinville Chapter 5 - Woodinville’s Regional Efforts First and foremost, the City of Woodinville is proud to be regional partners with the other cities and entities within and outside of King County. Despite its relatively small size, Woodinville is home to, or in close proximity to several critical facilities, including the Waste Management Cascade Recycling Center; the Brightwater Wastewater Treatment Plant; DTG Recycling Group; regional trails such as the Burke-Gilman, Sammamish River, and Eastside Rail Corridor; State Route 202; and Northshore Athletic Fields. While Woodinville is honored to play a crucial role in the region, the City has devoted considerable resources to addressing and funding resolution to and mitigation of these facilities. First, the Cascade Recycling Center in Woodinville is the only recycling facility located within the Northeast service area (see Comp Plan at 2-9, 5-17). It is the second busiest waste handling facility in Northeast King County, and processes a comparable tonnage of materials to KCSWD’s busiest transfer stations, with the exception of Bow Lake (See chart below).1 As the home of the Cascade Recycling Center, whose service area is vast, Woodinville experiences increased truck traffic, litter and debris, and it requires additional law enforcement activity (Attachment A). Secondly, Woodinville faces the threat of negative impacts from various seismic scenarios related to faults at or near the Brightwater Wastewater Treatment Plant. For example, as noted in the Draft Supplemental EIS on Brightwater, if an earthquake affects Brightwater’s water flow storage, overflows can be anticipated at the Woodinville Pump Station (see Draft Supplemental EIS on Brightwater, Figure Thank you for your comment.

Given Woodinville’s existing contributions to waste handling in this region, the City is aware of the importance of mitigating the impacts of waste handling and disposal facilities on the surrounding communities (Attachment B). 1The Comp Plan refers to the Cascade Recycling Center as a materials recovery facility, which is distinct from a solid waste facility. Nevertheless, it is worth comparing the tonnage of materials being processed in regional facilities in the solid waste system, regardless of whether those materials are recyclables or garbage, because both types of facilities have similar impacts on their host cities. The following Factsheet on the Cascade Recycling Center states that an average of 35 tons of recycling come through hourly: http://wmnorthwest.com/cascaderecycling/gif/factsheet.pdf. Woodinville’s conclusion that the Cascade Recycling Center processes more tonnage of materials than almost every transfer station in King County is supported by comparing this Factsheet with the information contained in Table 5-1 of the Comp Plan Impact Bioenergy (Srirup Kumar) Chapter 5 p. 142 Disaster Preparedness (5-12) Consider the RNG potential of organics for fuel security for the SWD to act "in island mode."

Make it clear that other options may be considered (and this Plan is not the siting process). The discussion of the NETS siting process should generically indicate that there are a minimum of three options for the Houghton facility, for example: 1) no action (keep as is), 2) close it and go through the siting process for a modern station, or 3) pair it with another new station to be sited in the general vicinity but have limited level of services at each. Please note drawbacks of the 3rd option: the operating costs for the two 'paired' facilities would exceed the cost of operating a single modern station, and each of the paired sites would fail to meet some service level criteria on their own. The Plan should be edited to clarify how the current facility would remain as is ("no action" alternative) versus distinguishing that from the option outlined under "Cost" (converted to a self-haul only facility); it should be clearer that these are distinct options. Federal Way Chapter 5, pg 5-21 Please correct The space has been removed in the word County. Federal Way Chapter 5, pg 5-22 The discussion of operating cost should be revised. The draft Plan suggests Houghton could remain open as a self-haul station, while a second Station is sited and built, to be dedicated for commercial haulers only. However, this approach would be more expensive to operate than a single modern transfer station (a more cost-effective solution which fits with the typical weekday vs. weekend use patterns for franchised haulers vs. residents/self-haulers). The existing Houghton Station does not meet several Service Level criteria. Please make revisions so that the The “Operating Costs” section as it is written says that keeping Houghton open and operating “as is” would be less expensive than either a new NERTS or a combination of facilities (including a potential option to keep Houghton as a self-haul only station and building a new commercial facility).

Since County transfer station labor agreements mandate shift and staffing levels, it is not apparent that operating costs "would be lower" for the "existing Houghton Station" plus a "hauler-only station" than the cost of operating a modern, combined station. For example, while "self-hauler" station may receive less tonnage, it will have several times more transactions than a hauler-only station. Labor agreements imply that KCSWD would find it challenging to operate and maintain Houghton transfer station "weekends only" just for self-haulers. Federal Way Chapter 5, pg 5-22 Please revise the language so it uses the text in more recent documents such as the Transfer Plan (KCSWD 2006b) Table 2, and draft 2013 Plan, which both indicate for Houghton: "space exists for station expansion ... inside the property". The new North Seattle station was reconstructed in place, demonstrating the potential for station compatibility in a more dense setting. Constructing the Bow Lake TS involved excavating a former landfill to create space to build the modern facility. A similar approach with appropriate mitigation and latent landfill gas recovery will, by default, be an option when siting any new transfer station, and as such, the Plan should not preclude this option. The language that is used under the “Level of Service Criteria” is referring to the transfer building and the existing transfer station footprint. While excavating the landfill would be a possibility, it is not discussed in Chapter 5 because the City of Kirkland has expressed an interest in closing the station and locating another station on a different site. Federal Way Chapter 5, pg 5-23 It is unclear how the combination of two stations would meet the level of criteria any better than a modern full-service transfer station. While it is possible that 'paired' northeast transfer stations might allow better geographic distribution closer to distinct sets of users in a given area, all service level criteria would be met when siting a single full-service transfer station (as evidenced by the new Bow Lake, Shoreline and Factoria stations).

Please edit the text so this is clarified. Please edit this text so it does not imply the preferred approach is to site a "commercial only" transfer station, since operating two distinct urban stations does not appear to provide equitable service or meet all level of service criteria. Federal Way Chapter 5, pg 5-23 This paragraph should be revised to address the potential for a modern transfer station at the Houghton site (in which case the entire menu of recycling options would be designed in). Due to the higher cost of having two separate stations operating as a "pair" or "combination", but lacking all services expected at modern transfer stations, avoid assuming ratepayers will support the "dual" or "paired" station approach. I In addition, KCSWD operations and outreach will be complicated by having to train self-haul customers about the difference between these two transfer stations from the other five "urban" stations, including why sets of customers are denied access to a potentially more convenient transfer station.

Kirkland Chapter 6 As recently as the mid 2000’s, it was anticipated that the Cedar Hills Regional Landfill in Maple Valley would run out of capacity in 2016.

The Plan presents three viable future disposal options that could carry the region beyond 2028 and include the further development of Cedar Hills, exporting our waste to an out-of-county landfill, and siting and building a waste-to-energy (WTE) facility. We believe that it is our obligation to our rate-payers to maximize and exhaust the use of our existing resources and infrastructure before considering alternative methods of disposal. While waste export is a relatively affordable, tried and true disposal method in other neighboring jurisdictions such as Seattle and Snohomish County, we believe that it is our responsibility to manage our own waste in our own county and so do not support the waste export alternative.

Woodinville contends that Option (1) is the best available option based on existing information. One of the advantages of Option (1) is that it is the lowest cost option overall (Comp Plan 6-18; EIS 5-33). Not only is Option (1) more affordable, it also takes advantage of the KCSWD’s experience in landfill operation and is consistent with county policy to maximize the life of Cedar Hills landfill (Comp Plan 2-20, 6-6). Yet another reason why Option (1) is the best path forward is that it has the lowest projected greenhouse gas emissions (Comp Plan 6-17). Options (2) and (3) are less desirable than Option (1). As an initial matter, the increased travel distances associated with Option (2) “could result in greater cumulative vehicle emissions and potentially greater long-term air quality impacts” (EIS 1-11, 5-8). Related to this concern, Woodinville requests the specific locations KCSWD is considering sending waste. The EIS states that the out-of-county disposal location would probably be in a rural area of eastern Washington, eastern Oregon, or Idaho (EIS 5-8), and the Comp Plan lists four specific “potential locations” for landfill disposal (6-8). Irrespective of the ultimate destination, however, Option (2) is not an attractive long-term solution because whatever disposal location the exported waste goes to will have a limited lifespan. Option (2) also presents challenges in terms of modifying transfer stations for rail-ready transport (Comp Plan 6-7; EIS 5-1). Moreover, the EIS indicates that rail capacity constraints may “increase the need for capacity increases in the relevant rail corridors” in 2028 (EIS 1-12).

Rail capacity would also be an issue with Option (3) (Comp Plan 6-10). This rail capacity issue would not arise with Option (1), however, until 2040 (EIS 1-11). Thus, Option (1) would provide policymakers with 12 more years to address rail capacity and to take advantage of waste disposal technology developed in those years. The EIS states that it is currently unknown what intermodal facilities Option (2) would rely upon to export waste but it is likely to be facilities located in south Seattle or south of Seattle near the existing BNSF Railway and Union Pacific Railroad Tracks (EIS 5-26). Woodinville seeks to know if KCSWD is considering any other specific rail lines or facilities for all three options and how many facilities KCSWD anticipates would be required to sustain these options. Another negative effect associated with Option (2) is increased traffic-generating activities at intermodal facilities. Specifically, the EIS estimates that Option (2) could add 156 transfer trailer loads (312 trips) on an average weekday, and approximately 73 transfer trailer loads (146) trips in 2028 on an average weekend day on local roads that provide access to the out-of-county landfill (EIS 5-26). Therefore, Woodinville currently supports Option (1), opposes Option (2), and seeks further information as KCSWD continues to evaluate the three options outlined in the Comp Plan. The City further encourages the County to continue to explore Option (3), a waste-to- energy facility, as a possible long-term solution along with others that promote efficient and effective service with minimal impacts to surrounding communities.

Landfills are the subject of controversy for populations located in proximity of the landfill and are guaranteed to face fierce opposition when proposed for continued use, expansion or as new facilities. The energy consumption, wear and tear on roadways, noise and contribution to traffic congestion are all negative impacts of heavy vehicle trucking to landfills. All landfills have a limited life before they run out of capacity. The life-cycle costs of a waste to energy facility as compared to the continued use of landfills demonstrates a greater long-term cost benefit to the citizens of the county. The need to replace traditional energy sources with alternative energy has demonstrable environmental and sustainability benefits. King County has prided itself in the past with providing a leadership role in the national trends toward sustainability.

That is the only long-range sustainable solution. Treatment needs to begin close to the points of origin, to reduce transportation costs and the volume of waste. Locally-hosted micro-treatment facilities, probably ones that employ cargo-containers, is the most likely alternative considering current technology today. Combining solid waste treatment with sanitary sewer conveyance systems allows for reduction of weight and leveraging recent technology advancements with aerobic microbes. Treatment of solid waste would become more rapid, efficient, and odorless using aerobic treatment processes. This is a win-win for both solid waste and sanitary waste treatment systems.

Republic Services Chapter 6 - Disposal In a recent study on Incineration paid for my King County tax payers , the study estimated the cost of mass burn incinerator at 1.1 BILLON dollars! Are we really going to ask our community to pay for this when there are already several facilities already capitalized and ready to go? The study group could not answer questions regarding air bourn containments’ produced at the incinerator. Mass burn incineration should not be considered in the comp plan at all. It is not a new technology and the harmful effect on health are in question. Our regional has millions of tons capacity for king county. Washington does have state of the art facility that exceed our federal and state standards. Here they are list below. There is no need to spend 1.1 Billon dollars on a facility that we don’t need and may have harmful effects on our health. Mass burn incineration should be stricken from the Comp plan. Washington Landfill Capacity: Roosevelt Regional Landfill has approx. 2.5 mil tons of capacity for about 100 years and is already producing electricity in the State of Washington Wenatchee landfill has 30,889,197 tons left Cowlitz has 52,787,279 tons left Oregon Landfill Capacity: Columbia Ridge has an estimated 103 year life span, and has permitted tons left of 265,122,000 Finley Buttes has an estimated 100 year life span, and has permitted tons left of 100 million tons Wasco has an estimated 118 year lifespan with total capacity of 19 million tons, very low volumes per year.

Thank you for the opportunity to respond and Carnation looks forward to working with King County as we move into the future. Thank you for your comment. The Plan includes a recommendation to further develop Cedar Hills to maximize disposal capacity. Eric Hudson Chapter 6 - Disposal Sieze this Opportunity - Create the Cedar Hills Wilderness Preserve! Cedar Hills is an "Accidental Landfill". It is an environmentally sensitive area and the worst possible location for a waste facility. It's proximity to the Cedar River and Issaquah Creek make it too risky to continue operations. There are many many better locations for solid waste. At less sensitive locations, it would be easier to incorporate new technologies and conduct research on recycling the solid waste. As leaders for the county I ask that you begin plans for the future to dispose of waste at a less sensitive, less populated area. I ask that the Cedar Hills landfill be designated a Wilderness Preserve and plans be made to convert the landfill area to a Natural Area. Let's allow Nature to heal and wildlife to return.

Still more costly alternatives include siting and building incineration or digestion systems, which produce energy as a by-product (but at a higher cost than existing power utilities, so this energy production could be categorized as "cost subsidized"). Further, these more expensive disposal options would still require landfill disposal of residuals or ash, along with related waste export infrastructure, so these related expenses should be accounted for consistently in cost comparisons. The Draft Plan estimates a capital cost of $1.1billion for a "mass-burn" incinerator - roughly four times higher capital cost than increasing permitted local landfill capacity from 2028 through 2040. The City's preference is for disposal options that sensibly maximize waste diversion and recycling practices while maintaining capital and operating cost efficiencies that are in the best interest of the ratepayers we represent. As such, the more costly incineration option is cause for concern, and the City would appreciate knowing the additional cost Federal Way ratepayers would be asked to bear if this disposal option were selected. The County Executive will consider input on the Draft Plan to propose a recommendation for the future disposal method to be included in the "final" Plan. The City is, however, concerned that the process for cities to provide advice and input as described in Section 5.1of the Solid Waste Interlocal Agreement may be overshadowed. Related concerns are detailed in the City's comments on Chapter 6 of the Draft Plan. Any decision Updated April 17, 2019

Thank you for your time and consideration Janet Dobrowski Chapter 6 - DIsposal Your draft talks about “Equity and Social Justice”. “Equity is achieved when all people have an equal opportunity to attain their full potential. Inequity occurs when there are differences in well-being between and within communities that are systematic, patterned, unfair, and can be changed. These differences are not random; they are caused by our past and current decisions, systems of power and privilege, policies, and the implementation of those policies.” I maintain you are not even following your own principle. It is UNFAIR to continually put the burden of these facilities on our neighborhoods. Our “well-being” is far from equitable from other communities. “Social justice encompasses all aspects of justice, including legal, political, and economic; it demands fair distribution of public goods, institutional resources, and life opportunities.” Fair distribution? Not even close - we are willing to share – send it to one of the affluent neighborhoods! The draft talks about siting new transfer stations and that “that any negative impacts of the facilities do not unfairly burden any community.” So in deciding whether or not to expand the landfill and lengthen it’s life, why isn’t consideration given to OUR communities concerning any unfair burden? We deal with odors, noise, truck traffic, garbage, rodents and the always present burden of not really knowing if there are any contaminants in the air that we are breathing. Is that not burden enough? Thank you for your comment. Equity is a consideration in selecting a long term disposal approach. Updated April 17, 2019

Cedar Grove was established AFTER we moved in and Cedar Mountain Reclamation just started up in the last couple years. My husband and I will be dead before Cedar Hills closes (if it ever does). Janet Dobrowski Chapter 6 - Disposal The draft only has 3 options: Expand the landfill and lengthen its life thru new permitting. NOT my preference. This, to me, is a self serving option. King county permitting its own landfill to expand – how convenient. The way the options have been evaluated, it seems a foregone conclusion that the council will select this option. There seems to be a clause that states there must be a $90 million reserve for monitoring and maintenance AFTER the landfill is closed. To date, there is only $25 million. What has King county been doing all these years? Have they been dipping into it so as to pretty much guarantee there will never be enough to close it? Is the $9 million/year for financing refuse area development with rate dollars managed in the Landfill Reserve Fund why it’s so low? I don’t believe the County is truly serious about closing the landfill and will do anything necessary to keep it open and extend its life. If it did, it would do more to fund this reserve. As it is, it looks like they may never have the required reserved. oThe draft stated that it needs to have a 7 year period to begin to close the landfill and take into consideration all underlying contracts. Again, the county is not serious about closing the landfill. If they had been they would have started the process for the current closing date, rather than squeeze out additional pits. Export – This option doesn’t seem to be one the council would seriously consider, but it is our preferred option. Thank you for your comment.

The team concurs that this is simply not accurate and true. Facts are ignored. Especially alarming are the false Greenhouse Gas emission volumes given for the Cedar Hills Landfill. From a scientific perspective, the climate is warming at an alarming and unnatural pace and Greenhouse Gases from landfills, including Cedar Hills are considerable contributors to Global Warming specifically in contrast to other viable and environmentally proven alternatives such as recycling, anaerobic digestion, energy and material recovery systems etc. The concept of landfilling is an outdated approach for handling modern waste appropriately. Thank you for your comment. To ensure that greenhouse gas emissions for disposal options received comparable evaluation, the plan used models used by the U.S. Environmental Protection Agency and the Washington Department of Ecology. Meghan Brookler Chapter 6 - Disposal When assessing the true cost of landfilling untreated and still reactive solid waste, landfills are significantly more adverse and environmentally detrimental than other viable alternatives. The recent King County Waste-to-Energy/Waste Export Study (prepared by the Normandeau Team) made 27 recommendations that are vital in the process of evaluating viable economic-ecologic options. These key elements for King County were not included in either the DSWMP nor the DEIS. Without this information a proper evaluation cannot take place and the plan should be halted and updated accordingly. It is essential that a comprehensive environmental and legally defensible analysis with an integration of these findings be undertaken. It is assumed that this comment references Section 4.1 of Normandeau’s 2017 Waste to Energy Options and Solid Waste Export Considerations report. The items listed in that section would be considered as possible next steps if waste-to-energy is pursued as a means of long term disposal.

Recycling faces significant challenges and these are not adequately addressed in the plan. In order to move towards a 70% recycling rate a much more aggressive local infrastructure is required including moving away from landfilling. documented to be 54%. There is no doubt that achieving a 70% recycling rate will be challenging, but having a landfill does not preclude aggressive recycling. Meghan Brookler Chapter 6 - Disposal It is important to know that the current DSWMP is focused on landfilling, which is the least sustainable option. Landfilling ranks lowest by the US EPA and comparable international waste management hierarchies. Landfilling offers the public the least viable/sustainable environmental option and is not economical when all costs and potential revenue streams are included. Thank you for your comment. Meghan Brookler Chapter 6 - Disposal The Draft Solid Waste Management plan fails to address an integrated approach that offers many benefits in regards to the reductions in greenhouse gases and other environmental pollutants into air and ground, the creation of jobs, revenues, recovery of materials recycling/upcycling and waste avoidance opportunities. These options will also eliminate the need for any additional landfill expansion and will save King County and its residents hundreds of millions of dollars. The Plan discusses many approaches that are used together including possible long-term disposal options and their impacts to the environment, greenhouse gas emissions, jobs, material recovery and revenue. Meghan Brookler Chapter 6 - Disposal It does not seem that the DSWMP has been thoroughly updated and comprehensively reviewed for a number of years. For example, the Plan lacks current innovative and technical solutions. The Public Review Draft Plan issued in January 2018 was an updated version of the 2001 Plan.

The 125,000 MTCO2e comes from the 50 year model. rounded to the nearest thousand). The higher number in the plan was for the 50-year scenario. SCA Chapter 6 - Disposal If there was too much waste for the capacity of the WTE facility in 2048, it seems like other disposal options could be considered correct? Is capacity projected to increase well above the 4,000 ton capacity after 2048? Tonnage is projected to increase steadily after 2048. Other disposal options (such as export) could be considered beyond 2048 instead of building an additional mass burn facility but the total disposal cost per ton for that combination option would add the cost of the parallel disposal system to the continuing operation cost for the original mass burn facility. SCA Chapter 6 - Disposal Would having two different systems be more expensive than two WTE facilities? Is there analysis on this? No, having two different systems would not be more expensive than having two waste to energy facilities. The Normandeau report includes information that could be used to do this analysis. Zero Waste WA Chapter 6 - Disposal We are strongly opposed to a waste-to-energy option. This does not make sense from an environmental or economic perspective at this time. Thank you for your comment SCA Chapter 6 - Disposal, p. 6-17 Second, the chart on the 6-17 shows the cost/ton for WTE as $121 at year 20. However, in the model the cost/ton is $37 in year 20. The 2017 Normandeau report estimated that in year 20 (actually, the 21st year when all bonds are paid off) the cost per ton for the mass burn facility drops to purely operating cost. However, the capacity of the mass burn facility also is fully used in year 20. An additional expanded mass burn facility must be built to handle the growing waste in the regional system in year 21 and beyond. Showing only the 2048 operating cost for the first mass burn facility does not account for the full cost of disposal given that significant new capital investment (and operating cost) must be undertaken for a new mass burn facility. So in Figure 6-9 to show an approx. 20-year apples-to-apples comparison with export we did not show either the drop of the bond payments for the first mass burn facility or the new capital cost for the additional mass burn facility.

Janet Wall Chapter 6 - Illegal Dumping I have been recycling since it was first introduced in Seattle by opening transfer stations to take recycling materials—newspapers, cans & bottles. Issaquah has used Recology Cleanscapes for a number of years now, and I really like their service. I can go to their store on Gilman and take in my household batteries, block Styrofoam, defunct computer parts, small appliances, and other items that would ordinarily be hard-to-recycle. Clean plastic bags and plastic films can be recycled now by putting them in larger plastic bags and placed in blue recycle toters. The people at the store have been very helpful about telling me where I can recycle items that they do not take—like old oil and car batteries. As I am able to recycle or compost almost all of my household waste, I have very little garbage and have gone to having a monthly pickup for more than a year now. I also pick up and recycle or compost items that is litter along SE 56th St. People are dumping all kinds of items along the roadside, so I appreciate being also able to take items such as old tires, large metal pieces, and even chunks of concrete or asphalt to occasional nearby recycling events. I wish people wouldn’t litter because it is a lot of work to pick up all their trash, sort it, and clean it enough so that it is suitable for recycling or composting, but it is good that I am able to get rid of most of it. Perhaps we need some more public announcements on TV to discourage people from littering. Almost all the litter I see is obviously intentional, not accidental littering. Thank you for your comment and your commitment to waste reduction and recycling. The division has a program to clean up illegal dump sites on public and private land.

I’d like you to consider is the gasification or Liquefication. They have machines in Japan specifically in Yokohama, that can turn waste plastic into oil diesel and gasoline. I think you really should look into this because these are machines that you can buy. You could ship them to King County. They are scalable to the amount of plastic you need to process. They work on the same principle. They heat up the plastic, gas is released and condensed into oil. This oil can be refined into gas or diesel. I hope you look into this. Thank you for your comment. There is a discussion of potential technologies to consider in Chapter 6.

Proximity to rail facilities would be desirable for shipment of ash to a proper and safe final disposal location. Recycling is an important component of such a facility, as is valuable materials recovery must be a component to be employed prior to final ash disposal. Waste reduction by incineration alone should also be explored as to its environmental and financial viability.

Valuable materials recovery from the ash should be a component of this type of waste reduction operation. This type of high temperature combustion facility should be capable of handling used tires, non-hazardous contaminated soil, dredge spoils, sludge, and other such wastes. This site is served by rail facilities for cost effective transport of ash to a final disposal location. Pursuant to RCW 70.95.010(8), incineration is equivalent in the disposal hierarchy to landfill and energy recovery operations. Continue a strong emphasis on education, incentives, and recycling. Federal Way Chapter 6, pg 6 -5 The County has a preferred future disposal method (waste export), per KCC Title 10 - including RTS-1, RTS-3, RTS-5, RTS-16, and 10.25.060 (A) and (B). Further, the 2016 King County Comprehensive Plan (2016 Update) (King County 2016a) indicates that "King County should maximize the capacity and lifespan of the Cedar Hills Landfill" Disposal method selection results from stakeholder input, cost analysis and policy review of an array of options. ideally, this Plan will outline options and make recommendations . However, "Approval" of this Plan in itself should not be described as the mechanism where the next disposal method will be "selected". Per Section 5.1 of the Solid Waste Interlocal Agreement (SWIA): if no decision is made by circa 2021 to expand Cedar Hills capacity, the County will engage in advisory committee consultation to seek input on the selection of the next disposal option for the system, along with a discussion of extending the term of the SWIA. Note that the WTE disposal method presumes extension of the SWIA's term Thank you for your comment. The Plan includes a recommendation to further develop Cedar Hills to maximize disposal capacity.

Regardless of the disposal option ultimately 'recommended' in this plan, if that option favors closure of Cedar Hills it will trigger Section 5.1 (based on the projected closure year). In view of these factors, this section would more appropriately be titled: "Overview of Major Disposal Options for this System" and the text revised so it does not infer this Plan's approval is the sole mechanism for selecting a disposal option. If no new Cedar Hills capacity is planned for, it follows that MSWAC & SWAC consultation would be triggered to consider a range of disposal options followed by amendment of the Plan as needed. Federal Way Chapter 6, pg 6-10 This discussion raises potential issues that warrant more direct engagement with rail service providers to better determine the likelihood of adverse impacts. Also, the Plan should indicate if other local jurisdictions that already export waste by rail have similar concerns (and if so, how these concerns are being addressed). The Plan should also address what alternatives would be put into play if the transfer system and/or the disposal method became unavailable for a period of weeks. Presumably if transfer trailers could still haul the waste, it would be temporarily stored - likely at Cedar Hills landfill.

Thank you for your comment. The typo has been corrected. The post-closure reserves discussion has been edited. Federal Way Chapter 6, pg 6-14 There is debate regarding the accuracy or applicability of EPA's WARM approach when applied to WTE, including how it accounts for biogenic C02, and presumes WTE generated energy fully offsets other energy source emissions (which still occur in spite of adding WTE-produced energy into the grid), plus the relative scale at which emissions and energy are produced from conventional sources vs. WTE, and also how landfill methane impacts are applied. These discrepancies should be addressed more fully in the Plan since the WTE data shows a wide range of net emissions, presumably reflecting such discrepancies. In short, it is unclear in the draft text why a wide range is shown in Figure 6-7 for WTE. Thank you for your comment. The range indicated in Figure 6-7 has been corrected to 12,000 -80,000 MTCO2e.

Internally, King County has committed to reducing GHG emissions from its operations, compared to a 2007 baseline, by at least 15 percent by 2015, 25 percent by 2020, and 50 percent by 2030. The County has further committed to achieving net carbon neutrality for the Department of Natural Resources and Parks by 2017, with the Wastewater Treatment Division and the Solid Waste Division each independently achieving carbon-neutral operations by 2025. The 2015 SCAP outlines the results of technical analysis that established specific, quantifiable pathways to achieving the overarching GHG emissions reduction targets at both the countywide and government operations scales." The WTE disposal option appears to work against achieving these targets, and the Plan does not indicate how the County will "make up" for WTE's GHG emission increases. Federal Way Chapter 6, pg 6-14 Footnote 1in Appendix D Table 1appears to provide a reason for the low and high range that is shown in this Fig. 6-7, but says that the inputs used in the model that generated these figures "are not available" which raises concern about accuracy and assumptions that resulted in these estimates. The County should verify how the range was calculated, and an explanation added to a footnote in Figure 6-7. Assuming Fig. 6-7 depicts the base year of 2028, please clarify if the WTE plant is operating at full capacity (4,000 tons per day), or the MSW tonnage generated within this service area at that time (since initially only three 1,000 ton per day WTE lines are needed for this system's MSW). Please show the likely scenario of MTC02e production when WTE is at full capacity (4,000 tons per day) and The estimates referenced in footnote 1 were made by consultants with deep experience with waste to energy facilities. The division’s interpretation of the reasons for the range of results is shown in footnote 1. The WTE facility is sized to reach capacity in year 20, not year 1 (2029). Operations would be most efficient when the facility is at or near full capacity. The WARM greenhouse gas estimates are calculated for a common base year in 2029. Updated April 17, 2019

What percentage of bypass wastes are counted toward the "landfill gas recovery" input, and is that factored in as an additional emission in this table? Federal Way Chapter 6, pg 6-16 The WTE discussion indicates 'all' of this metal will be recovered. Please state the projected recovery rate. The projected recovery rate is up to 50,000 tons of ferrous and non-ferrous metals. This would increase the County’s overall recycling rate by about two percent. Federal Way Chapter 6, pg 6-16 Unless there are proven and cost-effective metals recovery methods, it may be more realistic to not count this 2% as a given outcome, and therefore omit this section. Are there examples of other WTE plants recovering metal in this manner and at the proposed scale of this WTE option, with data showing it economical to do so? How much does it cost per ton to recover this metal? Is that cost factored into the cost per ton projections? Is there even a cost-effective way to recover non-ferrous metals from slag and ash once it is subjected to high heat? The two percent increase is based on the estimated metal content of our waste in 2029. The 2029 composition is calculated using the 2015 study of our waste characterization. The Normandeau report findings are based on Pasco County FL, and Spokane WA ferrous and non-ferrous metal recovery percentages of approximately 4% and 0.8% respectively when using advanced metal recovery systems on mixed municipal solid waste processed at those plants, (this would mean nearly 100% recovery for our waste that contains approximately 5% metal). The cost to recover the metal is included in the $21M of additive construction costs (Ash Equipment, Electric Interconnect, and Site) and the operating cost of $31.50 per ton. What portion of those costs are for metal recovery is not available from these planning level estimates. Yes the revenue and costs are factored into the cost per ton projections.

Advanced material recovery system costs have yet to be developed for the Solid Waste Division system. This work is being considered as part of the new South County Recycling and Transfer Station. Federal Way Chapter 6, pg 6-17 Presumably the $229 million in capital costs won't be spent "as soon as" approval of cell construction occurs. It would instead be spent over the period of time during cell construction that creates landfill capacity until 2040. Please consider clarifying this period of time. This footnote appears to be the only text reference to "Area 9" in the Plan. There is an "Area 9" represented in Figure 2.5, but it is likely different than the area that would be used in expanding capacity to 2040, so please add explanatory text. This table has been removed from the Plan. Federal Way Chapter 6, pg 6-17 It is not clear why the 2017 capital amount is higher than the future amount. Do these figures compare, or do they come from a different base? This table has been removed from the Plan. Federal Way Chapter 6, pg 6-17 This note seems to indicate that the WTE option overbuilds initial capacity and requires waste import to run all four 1,000 ton per day lines. (It doesn't appear that the intent is to not start one of the 1,000 ton per day lines for several years). What is the year when our system- generated MSW provides sufficient input that makes it economical to begin operating that fourth line solely on waste generated within our system? (Presumably the fourth line is not started just for our daily MSW ton #3,001). At 4,000 tons per day, operating continuously, WTE would process over 1.4 million tons of MSW. While WTE facility downtime will mean a lower total tonnage will be burned in practice, Figure 3.3 doesn't show when that level of "tons disposed" will be reached - presumably it would be years past 2040. The Yes, the WTE option initially is built to reach capacity in year 20. Bypass waste and ash would be exported throughout the life of the WTE facility. The operators of the WTE facility could seek outside waste until waste from our regional system uses the facility’s full capacity. For year 21 and beyond, an additional decision would be needed to build additional WTE capacity, export any municipal solid waste beyond the capacity of the initial facility, or use alternative disposal approaches.

It would also include a chart depicting annual waste import, by-pass waste export and ash export tonnages, as well as projected tip fee costs - at the beginning of the waste import phase, during the waste import phase, and then the phase where the WTE facility operates at 4,000 ton per day capacity with system-generated MSW. How much will it cost to arrange for inbound rail or truck capacity to enable contracting for this required waste import? It is unclear that other nearby MSW systems would select disposal capacity that tapers off - unless it is somehow cheaper than their current system. The Plan should explain why an outside MSW agency or system would seek to enter into a contract for "waste import" into our system when Figure 6-9 shows waste export is less expensive than WTE. Clarify if the County is considering having ratepayers subsidize the import of waste from outside the system, and if this also includes subsidizing the disposal costs for that waste's ash, and how much that subsidization would cost our system’s ratepayers.

Ultimately this regional system is most equitable when Cities and advisory groups are enlisted as partners who are empowered to provide input in a timely manner. Federal Way Chapter 6, pg 6-6 Please add the text below regarding benefits of conserving current permitted Cedar Hills capacity. Make it clear which practices (such as WRR) preserve landfill capacity and provide value by delaying or avoiding inevitable future costs. "A comparative evaluation of alternative disposal options (R.W. Beck 2007) that are compatible with increased recycling and capable of handling King County's waste while meeting applicable regulations indicates that disposal at Cedar Hills is the most economical way to handle King County's solid waste. It is significantly less expensive than the projected costs of other disposal options, including transporting waste to an out- of-county landfill or to a waste -to-energy or other waste conversion facility. By extending the life of the landfill and delaying the transition to a new disposal method, the county will be able to delay the unavoidable rate increases that will be needed to accommodate this transition." This section of the Plan should make a brief but clear distinction between the topic "current permitted capacity conservation" before discussing the steps and costs required to increase permitted capacity in the "Further Develop Cedar Hills" discussion. Thank you for your comment. The Plan includes a recommendation to further develop Cedar Hills to maximize disposal capacity. Updated April 17, 2019

E-86 2019 Comprehensive Solid Waste Management Plan - July 2018Responsiveness Summary: Responses to formal comments made during the January 8 – March 8, 2018 public comment period Commenter Public Review Draft Chapter & Page Number Comment Response (Page numbers refer to the 2019 Plan) Federal Way Chapter 6, pg 6-7 The Plan should note that intermodal capacity could be shared, and that there is potential for cooperation among neighboring Counties and Seattle that could reduce rail costs or create other efficiencies of scale. Thank you for your comment. The suggested edit has been made. Federal Way Chapter 6, pg 6-9 Please explain what happens if the opposite occurs and tons are lower than forecast. Typically a 'put or pay' cost structure applies to WTE facility economics, meaning if tonnage minimums are not met, penalties or payments are still assessed. If factors like the economy or WRR efforts mean there is not enough waste coming into the WTE plant to cover the bond costs and operation costs, or to operate at peak efficiency levels used in this Plan's projections, who pays for this shortfall? Note that WTE operations require a steady supply of MSW to maintain efficiency, and note that this is a drawback compared to disposal options that are more readily scalable (e.g., changes to the total number of rail cars that make up waste export trains is relatively benign). Provisions to ensure that WTE facilities receive enough garbage usually are part of contracts for operating WTE facilities. The arrangements if the regional system produces insufficient garbage for efficient WTE operation have not been identified. Federal Way Chapter 6, pg 6-9 This disposal option should include all costs associated with operations. For example, the cost of transporting this ash and the associated tipping fee, as well as how the potential issues of waste export and even waste import (pertaining to rail capacity) still apply with the WTE option based on the initial capacity target of 4,000 tons per day. Provide an outline of related infrastructure (including intermodal rail capacity) required plus how ash will be conveyed to a rail head along with any bypass or non-processable wastes. Please show how the costs associated with these integral WTE operations have been factored into this plan, in order to allow a more complete comparison among options. WTE costs, which were based on Normandeau 2017 included the cost of ash export and export of MSW during scheduled facility maintenance. Import of MSW from outside King County was not included in the costs. Updated April 17, 2019

The tip fee increase in 2017 has already been in effect for over a year, while the other two tip fee increases are projected to take effect in 2019 and 2022. As a result, there will be a rate impact to ratepayers served by regulated solid waste collection companies in King County in years 2019 and 2022. This is illustrated in the table shown on the following page. (see original letter) Staff has no further comment on the cost assessment questionnaire. Bellevue Chapter 7, Fee structure In Chapter 7, the Plan discusses the possibility of potential changes in the solid waste fee structure. The Plan should clearly articulate that the MSWMAC has a role in providing input and feedback to the County when changes to the rate structure are contemplated. Additionally, additional clarification should be included regarding what aspects of the rate structure could be changed. Requested change (p.7-9): Add an explicit reference to MSWMAC's role in providing feedback to the County when changes to the rate structure are contemplated and provide more detail regarding the types of rate structure changes that may be considered. Thank you for your comment. The change has been made. Federal Way Chapter 7, pg 7-10 This was the conclusion of the 2007 Beck study, so consider revising the text so it says that the preliminary recent study appears to reaffirm this conclusion. This would avoid an impression that this is newly revealed or 'preliminary' information. Thank you for your comment. The suggested edit has been made.

It is agreed that there is strong logical support for considering such a change since many of the costs incurred by Solid Waste are driven by volume (as opposed to weight) such as handling costs, transportation costs and most importantly landfill costs. However, there are significant drawbacks to this proposal including: 1.It is much more difficult to measure volume thantonnage accurately.2.The additional processing could impact waittimes, personnel requirements and requireadditional equipment.3.There may be “equity” issues due todifferences in degree of compacting. Forexample, commercial haulers may carryresidential waste that is partially compacted.Self-haulers waste in general is notcompacted.4.The billing process would become morecomplicated and potentially confusing to users(am I being double charged).Since these changes are not included in this section, are we to conclude that this proposal is off the table since it is not practical? Although the Plan would allow a future change, at this time, the Division is not proposing to revise the fee structure. More discussion with our partner cities will need to take place before this change would be possible.

Puget Sound Clean Air Agency Composting/ Air quality Finally, in the Draft SWMP, Alternative 3 of the Sustainable Materials Management indicates that it would expand recycling to include curbside yard waste pickup to all residences in King County, including those in unincorporated King County. The Agency supports that goal as it links to our goals to eliminate residential burning of yard waste and brush to satisfy statutory requirements. However, our support for this goal does not alter our strong interest in seeking real improvement in the air quality impacts from organics recycling operations. We believe that we should be seeking a way to meet all of our environmental objectives. Thank you for your comment. The division will be working with stakeholders to determine how to provide more processing capacity for organics so that odor concerns can be addressed. Zero Waste WA Definition Definition of compost: We recommend updating the definition to match the new definition adopted by The American Association of Plant and Food Control Officials: Compost – is the product manufactured through the controlled aerobic, biological decomposition of biodegradable materials. The product has undergone mesophilic and thermophilic temperatures, which significantly reduces the viability of pathogens and weed seeds, and stabilizes the carbon such that it is beneficial to plant growth. Compost is typically used as a soil amendment, but may also contribute plant nutrients. Thank you for your comment. The definition included in the Plan is derived from KCC Title 10 and RCW 70.95.030. Zero Waste WA Definition Definition of leachate: We recommend that the definition of leachate be clarified to indicate that the water percolating through the landfill has the ability to pick up contaminants.

The company was awarded a Washington State Clean Energy Fund Grant to build and operate a merchant commercial food waste AD facility on Vashon Island. Our private enterprise business model relies on three value streams to finance and sustain operations: a tip fee for organic waste recycling, the sale of renewable energy, and the sale of probiotic plant food derived from digested food waste. We are at great risk in this endeavor if we cannot secure a tip fee at a minimum equivalent to the present MSW tip fee at the County Transfer Stations. Decentralizing has the advantages of less trucking, less diesel fuel use, less traffic congestion, less odor issues at outdoor composting facilities, more building of a sense of community, and diversifying the number of organic fertilizers and soil projects made from recycled organics. Yet decentralizing has less economy of scale.

As previously communicated in its November 3, 2017 comment letter on the preliminary draft Plan, Bellevue's key solid waste interests are generally reflected in legislative actions taken by the King County Council in October 2017. The Plan should accurately reflect these recent actions. Specifically, on October 10, 2017, the King County Council took legislative actions that 1) cancelled demand management; 2) committed the County to planning for needed northeast King County transfer station capacity outside of Bellevue; and 3) established that there would be no further expansion of the Factoria Transfer Station and committed to the timely surplus of the upper Eastgate Way property. On October 30, 2017, Bellevue signed the Amended and Restated Solid Waste Interlocal Agreement (ILA) with King County. Bellevue signed the ILA with the expectation that King County fulfill its duties as prescribed in these recent legislative actions and look to serve the county's future solid waste demands through financially prudent and geographically equitable strategies. Bellevue is concerned that the Plan as drafted falls short of these expectations, Thank you for your comment.

Kathy Lambert General This letter and the attached marked up copy of the Draft Comprehensive Plan constitute my official comments. The final report should be integrated and not siloed. The items that cannot be recycled shou ld be put in a modern waste to energy plant, so they are recycled in that manner, produce power and dispose of the matter so it is not left for future generations to deal with. Thank you for your comments. Unlike the last adopted Comp Plan, this Plan includes a new chapter, Chapter 2 The Existing Solid Waste System. This chapter discusses how the entire system works together while later chapters focus on specific parts of the system such as sustainable materials management, transfer, and disposal. Kathy Lambert General There should be a sustainability model wherein biosolids are also used as fuel. There are toxins and pharmaceuticals in biosolids. The impact of the combinations of all these chemicals is unknown and leaves our land with potential for contamination. The European Union does not allow lands application of biosolids. We need to follow their example. King County returns the valuable nutrients and carbon from biosolids – a nutrient-rich organic product of wastewater treatment – to the land as a soil conditioner for agriculture and forestry. A portion of the biosolids are also composted by a private company and sold as compost for use in landscaping and gardening. These approaches contribute to sustainability by using biosolids to enrich soils, keeping them productive and healthy. Kathy Lambert General The lifecycle of our recycled products should be documented. When we ship some recycled products to China and other places we have no idea how they are being reused or disposed of. It is not true recycling if we don't know the outcome of the materials. The regional system relies on public and private participants, with private collection and processing companies responsible for ensuring that recyclable materials are reused under their contracts with the cities and county. For example, the division’s contract for processing of recyclables from county transfer stations states “The Contractor shall ensure that all of the recyclable materials collected from SWD sites are recycled per King County Code [KCC 10.04.020 DDDD], which specifies that recycling of materials includes transforming, remanufacturing, reprocessing, composting or re-refining materials into usable or marketable products, and marketing or distributing those products or commodities for Updated April 17, 2019

One of their- concerns is that our separation methods allows for contamination of the materials. I have seen very different sorting methods in Germany and Denmark, which produces a cleaner product to be on the market and compete with our recyclables. The regional approach to separation of curbside recyclables has evolved. Some materials were collected in separate bins when local recycling programs first began. Since the early 2000s curbside recyclables have been collected in one bin and the co-mingled recyclables brought to Material Recovery Facilities to be sorted, baled, and sold to be made into new products. The one-bin approach greatly increased the regional recycling rate but it relies on customers making the right choices about placing in their blue bin only materials accepted by their jurisdiction’s recycling program that are empty, clean, and dry. The division and its advisory committees have convened a Responsible Recycling Task Force to explore reducing contamination through more recycling consistency among jurisdictions, and customer reminders about recycling best practices, and other means. Kathy Lambert General Many of the suppositions given in this draft report need to be reconsidered. For instance the tonnage capacity of a waste to energy plant does not need to be built at the beginning for anticipated tonnage over the next 20 years. We have no way of knowing what changes will happen in packaging, regulations, recycling, reuse, etc. So building so much extra capacity is not necessary. We should model after waste to energy plants in Florida and Hamburg. They provide us with a clear, documented data system that is sustainable and we can measure the environmental impacts in a much more accurate and efficient way than landfills. Various choices regarding the size of a waste to energy plant were offered in the Normandeau 2017 report. Given the lengthy siting and construction process and need for disposal certainty over a reasonable time period, the waste to energy option assumed a facility that can handle county tons for at least 20 years before reaching capacity, after which an additional waste to energy plant or other disposal option would be needed. Twenty years also is more consistent with the plan’s planning horizon and allows comparison of the three disposal options over roughly the same time period. Kathy Lambert General Our landfill is quickly filling up. Going up another 50 feet will have impacts on the surrounding neighborhoods and on costs. The Further Develop Cedar Hills option would increase the landfill height 30 feet over the currently permitted height. The cost of increased height is Updated April 17, 2019

Kathy Lambert General The comparison numbers for a new cell have a range that is stated at its lowest number while the comparison of a waste to energy plant is compared at its highest price range. Capital and operating costs for the disposal options in Chapter 6 of the public review draft Comp Plan (January 2018) are presented as single numbers for each option instead of ranges. Costs for the Further Develop Cedar Hills options were estimated by the division. Costs for the waste to energy option were taken from the Normandeau 2017 report that presented credible waste to energy costs drawing on recent information and the consultant’s many years of experience with waste to energy facilities. Kathy Lambert General Taking the materials by rail is an expensive and uncertain option. We already know there are times when the rails are over capacity and we have no control over the long term costs. A waste to energy plant contains the materials and disposes of most of the matter here and provides certainty and predictability. Chapter 6 Table 6-2 shows the waste export disposal option to be more expensive than further develop Cedar Hills option but less expensive than the waste to energy option. Page 6-10 of the public review draft plan notes potential capacity constraints identified by the Washington State Department of Transportation and Normandeau 2017. Kathy Lambert General If we built a waste to energy plant now, it would allow us to use our current capacity to accept the fly ash until we can update our codes to be in line with European standards and science to declare it inert. Flyash is also needed in cement and there would be a market for it. In addition, our bottom ash could be used for road construction. Our 1,500 miles of roads are in need of repair and in places reconstruction. Having this readily available product for road bed would be another asset. Under Washington State Special Incinerator Ash Standards (Chapter 173-306 WAC) ash must be disposed separately from municipal solid waste in a special ash monofill. Although standards could change in the future, waste to energy ash is not currently approved in Washington for other uses such as roadbed material. Because Cedar Hills is permitted as a municipal solid waste landfill, the engineering, permitting, and financial feasibility of building an ash monofill on the site would need further evaluation. The public review draft plan assumed that the ash would be exported to an existing out of county ash monofill. Kathy Lambert General The metals would be recycled, which would help our environment too. The plan recognizes that more metals could be recycled with the waste to energy option.

Based on the studies, these options will provide more benefits, environmentally sound technologies that adequately destroy the toxic organic components contained in the waste and biosolids, while reducing the impact of air and ground pollution compared to landfilling. The DEIS is not thorough, is technically inaccurate, and not legally defensible due to the poorly written Draft Solid Waste Management Plan. Both the DSWMP and DEIS need to be stopped and comprehensively rewritten. The new plans need to be prepared based on viable, credible scientific facts and complete documents.

We envision a just and sustainable world where society responsibly produces, consumes and recycles. We applaud the overall approach and the waste prevention hierarchy. We are concerned, however, that the recycling rate has plateaued. We would like to see much stronger policies and actions in the plan to stimulate increasing the recycling rate (even though there is a challenge with the China Sword initiative at the moment). Zero Waste Vashon General The CSWMP presents a very detailed analysis of the recent status, challenges, and proposes several alternatives for future development and how King County deals with solid waste, recycling, and related issues. The main challenge centers around the Cedar Hills Landfill Facility capacity and projected life based on estimated waste volumes in the coming decades. ZWV is proposing that King County prioritize a de-centralized waste management approach which uses an integrated Regional - Distributed system. In order to reduce waste going to the central landfill, ZWV recommends that King County improve and expand the existing waste disposal / recycling infrastructure to increase local recycling rates, divert more organic materials to existing and new distributed local composting and anaerobic digestion systems, and greatly expanding waste diversion approaches such as ReUse facilities. Increasing the number and accessibility of local facilities will decrease overall waste transportation costs, road congestion and wear, greenhouse gas production and waste volumes needing disposal at the Cedar Hills Landfill.

ZWV strongly support CSWMP policies that positively affect the following: Increased Recycling Rates on Vashon : the newcommingled blue bin for curbside collection hasbeen a positive step forward for the Islandcommunity, however a majority of Islanders still“self-haul” their garbage and recycling to theVashon Recycling & Transfer Station. Improvementsat the Transfer Station are needed to facilitateeasier recycling and separation of garbage andrecycling by self-haulers.Improved Services at the Vashon Recycling &Transfer Station including : Food Waste Collection,Construction and Demolition Debris collection,Clean Wood Recycling, Electronics Recycling, Re-UseSite for collection of reusable construction materials(windows, doors, lumber, lighting fixtures, plumbinghardware,…)A KCSW funded feasibility study to evaluate anddesign an Island Compost Facility to handle bothYard Waste and Food Waste. Currently VashonIsland only recycles Yard Waste brought to theTransfer Station by self-haulers. This material iscollected and then transported off island to theCedar Grove Compost facility in East King County. Anon island facility would be more economical andeffective for Aerobic Composting of Island Yard &Food Waste.Thank you for your comments. SWD continually looks for ways to improve recycling. Food waste collection has been provided at the Vashon Recycling and Transfer Station since 2016. Other materials are evaluated as space configurations can be identified that are safe and allow for efficient vehicle movement. SWD agrees that an on-Island processing facility would be ideal. Cost and space are constraints as well as little assurance that should such a facility be developed that residents will pay to keep it viable.

Seattle-Tacoma International Airport (Port of Seattle) General Thank you for providing the opportunity to comment on King County's Draft Solid Waste Management Plan. Seattle-Tacoma Airport (SEA), owned and operated by the Port of Seattle, and located in the City of Seatac (City), provides airport facilities and services to meet the region's commercial and air cargo transportation needs. SEA is the primary commercial generator of municipal solid waste operating in the City and per WUTC regulations, relies exclusively on City contracted solid waste services that use King County's Bow Lake Solid Waste Transfer Station. To date, City and County solid waste services have served SEA with consistent, reliable, and responsive solid waste collection and disposal services. We appreciate collective efforts of City and County staff and applaud your progressive stance on Waste minimization as evidenced in this plan. SEA supports King County's proposed 70% waste diversion goal, which aligns closely with our own goal (60%). SEA also recognizes that achieving our waste diversion goal requires robust secondary material markets, access to material recovery services, and collaboration with Municipal and Regional partners. In light of those dependencies, SEA offers the following comments and welcomes future discussions regarding potential partnerships, pilot studies, or supportive efforts. Thank you for your comment.

The Plan is organized with a reference to the page number where background discussion of the action can be found. Kirkland General - LHWMP The City of Kirkland appreciates the work the Local Hazardous Waste Management Program (LHWMP) has done to reduce the impacts of moderate risk hazardous wastes on our environment through providing our residents and businesses with a reliable, safe, and responsible disposal option through a permanent drop-off location at the new Factoria Transfer Station and through periodic Wastemobile visits to the northeast County. In February, through the Sound Cities Association, the Kirkland City Council and staff were made aware of and surprised by a proposed 50.4% increase in the LHWMP fee schedule charged via a flat fee to our residents and variably to businesses based upon their service levels. As proposed, the fee increase would take effect in 2019 and be implemented incrementally over a six year period. The proposed increase also adds to the per-ton fees charged to private and commercial haulers at all transfer stations which has a direct impact on the rates cities charge to their customers. We have serious concerns about the general lack of communication and transparency on the part of LHWMP to its cities with solid waste interlocal agreements concerning the fee increase and the apparent lack of any tangible or meaningful improvement in services provided to our ratepayers in NE King County. The City of Kirkland strongly encourages the KCSWD and LHWMP to regroup and consider a less expensive, shorter term rate proposal that runs concurrent with the two-year King County biennial budget.

F-12019 Comprehensive Solid Waste Management Plan - July 2018
Options Considered for King County’s Next Disposal Method
The division used information on waste disposal options from the Conversion Technology Report (R.W. Beck
2007), the Waste-to -Energy Study (Normandeau 2017), and an updated Cedar Hills Site Development Alternatives
Final Report (KCSWD 2017a) to identify three options to meet the county’s disposal needs after currently
permitted capacity at Cedar Hills is used. A long -term disposal method was selected from the following three
options:
•Further develop Cedar Hills,
•Waste Export, and
•Waste to Energy (Mass Burn) Facility.
Further Develop Cedar Hills
This option would further develop Cedar Hills to maximize disposal capacity, extending the county’s 50-year
practice of managing its waste locally. To account for emerging technologies, the next disposal method would
not be specified, but criteria would be established for selecting the next disposal method. This option is
consistent with county policy to maximize the life of the Cedar Hills landfill. The Conversion Technology Report
(R.W. Beck 2007) and more recent division analysis concluded that Cedar Hills disposal is the most economical
way to handle King County’s waste. Other advantages include the division’s experience in landfill operation,
availability of space in a county-owned landfill with state of the art environmental controls, and collection of
landfil l gas to produce renewable energy. Challenges with this option include obtaining new or modified
permits to authorize further development, relocating buildings to make room for refuse, and continuing to
be good neighbors for the surr ounding community.
Features used in the re-evaluation of this option include:
•New landfill cells would be developed at the Cedar Hills landfill,
•The permit and the landfill would be modified to increase the height of the landfill from approximately 800 feet to
830 feet, to the extent that such modification would be consistent with the terms and conditions of the
Settlement Agreement, which requires King County to make a good faith effort to keep the maximum
height of areas 5, 6, and 7 of the Landfill at or below 788 feet above sea level,
•Division facilities currently located in areas permitted for refuse disposal would be moved,
•High-efficiency collection systems would continue to deliver landfill gas to the Bio-Energy Washington facility,
resulting in pipeline-quality natural gas, revenue for the division, and reduced greenhouse gas emissions,
•The added capacity would be sufficient to handle the forecast tonnage, maximizing disposal capacity at the
landfill,
•Consistent with long-standing practice, new development would be financed through rate revenues managed in
the landfill reserve fund,
•As Cedar Hills reaches capacity, previously described evaluation criteria would be used to select the next disposal
method, and
•A new disposal method would need to be ready for service when the new capacity at Cedar Hills is exhausted.

F-2 2019 Comprehensive Solid Waste Management Plan - July 2018
Waste Export
This option would export waste to an out-of-county landfill after currently permitted capacity at Cedar Hills is
used in 2028. Current county policy establishes export to an out-of-county landfill as the choice for disposal after
closure of the Cedar Hills landfill. Waste export by rail is a proven disposal option used by neighboring
jurisdictions, including the City of Seattle and Snohomish County. There are several regional landfills available by
rail with combined capacity sufficient to handle the county’s waste in the long term. (Table 6-1)(KCSWD 2017c).
This option would transfer a significant portion of the County’s waste management activities into the private
sector for long haul and landfilling. Challenges include modifying transfer stations for rail-ready transport, cost,
lead time needed for contracting and division operational changes, and potential rail service disruptions that
might arise from rail capacity constraints and weather events.
Features of this option include:
•The county would enter into a contract to export waste after current permitted capacity at Cedar Hills is
used by 2028,
•Waste would be exported to a yet-to-be determined out-of-county landfill,
•The out-of-county landfill would produce energy from landfill gas using an efficient collection system,
•The county would negotiate revenue sharing or energy credits with the out-of-county landfill for the
county’s share of waste that produces landfill gas that is then harvested for energy,
•Waste would be transported to the out-of-county landfill by rail, the preferred transport mode, based on
travel time, equipment requirements, payload, and capital costs (KCSWD 2017c),
•The division would buy container-ready trailers to transport rented rail-ready containers from transfer
stations to a rail intermodal facility,
•The division would modify its transfer stations so that municipal solid waste can be loaded into railroad
shipping containers, and
•The division would contract for an intermodal facility to transfer containers from trucks to rail.

Waste to Energy Facility
Under this option, current permitted capacity at Cedar Hills would be exhausted in 2028 and then all of the
region’s municipal solid waste would be directed to a waste to energy facility built in King County. As discussed
previously, a recent study identified a mass burn facility as the best waste to energy technology for consideration
by King County (Normandeau 2017).
This option would reduce waste 90 percent by volume and 75 percent by weight, while offsetting some costs
through sale of electricity and increasing recycling by as much as two percent. Challenges include facility siting,
cost, providing guaranteed amounts of feedstock, having unused capacity at the beginning of the operating period
with potential inefficient operation during periods when less capacity is used, possible shutdowns due to waste
deliveries below the system’s requirements, rail capacity constraints for ash and bypass waste export, and other
factors.
Features of this option include:
•For the first 20 years of operation (2028-2048), the facility would be designed to minimize waste that
bypasses the facility because it is too bulky or exceeds facility capacity, resulting in a 5,000 tons-per-day
plant built on a 40-acre site with five lines that could handle 1,000 tons per day each,
•To handle forecast tons, additional capacity would be required beyond 2048, or sooner if the actual
tonnage increases faster than forecast,
•The mass burn facility would include a tipping floor, pre-incineration screening of non-processable
materials at transfer stations, an infeed hopper, combustion chamber, ash collection, metals recovery,
and emissions scrubbing systems that use activated carbon and selective catalytic reduction
technologies to keep dioxin and other potential emissions below permit limits,
•The facility would burn municipal solid waste to produce steam, which turns an electrical turbine to
create electricity. Washington State does not currently consider electricity from a mass burn facility as
renewable,
•The ash produced as a by-product of the process would be screened to recover all remaining metal
for recycling,
•After screening, ash would be transpor ted to an out-of-county landfill where it would be buried
separate from the municipal solid waste in an ash monofill. Various groups are researching beneficial
use of incinerator ash; however, in Washington State the ash must be disposed in an ash monofill, and
•Non-processable and bypass waste would be transpor ted to an out-of-county landfill.

Waste -to-Energy in King County and the United States
In the late 1980s, both King County and the City of Seattle planned to convert from burying
municipal solid waste in a landfill to sending waste to a mass burn facility. Protests by the
public and environmental groups led both jurisdictions to abandon plans to build mass burn
facilities and instead shif t emphasis to recycling and waste reduction, along with exploring
waste export to out-of-county landfills. However, during the past decade, technological
advances in mass burn facilities and the emergence of other potentially viable waste
conversion technologies have resulted in renewed interest in these options for long-term
disposal once Cedar Hills has reached its permitted capacity.
The King County Waste-to-Energy Study (Normandeau 2017) identified a mass burn facility as the
best waste-to-energy technology to consider for the county’s solid waste system. T here are 77
individual waste-to-energy facilities in 22 states listed in the Energy Recovery Council 2016
Directory of Waste to Energy Facilities (ERC 2016). Sixty of the facilities are mass burn, 13 are
refuse-derived fuel, and four are modular. Mass burn is the most common waste-to-energy
technology, representing 78 percent of the industry technology in the United States. Most
facilities were built before 1996. The most recent plant was built in Florida in 2011 (operational
in 2015) and is a 3,000 tons per day facility. In the United States, 3,000 tons per day is the upper
capacity limit on the aging facilities from the 1990s. Small units with capacity of 1,000 tons per
day or less have been built and some have been redesigned to expand capacity. A 5,000 ton per
day facility, as proposed for King County, would be the largest mass burn facility in the United
States.

Dear Ms. Morehead:
The Washington Utilities and Transportation Commission (Commission) has completed its
review of the cost assessment questionnaire for the draft of the King County Comprehensive
Solid Waste Management Plan (Plan), submitted Janurary 9, 2018.
The cost assessment questionnaire in the Plan proposes three tip fee increases at all King County
transfer stations during the 2017 – 2022 Plan period. The tip fee increase in 2017 has already
been in effect for over a year, while the other two tip fee increases are projected to take effect in
2019 and 2022. As a result, there will be a rate impact to ratepayers served by regulated solid
waste collection companies in King County in years 2019 and 2022. This is illustrated in the

RE: Revised King County Draft Comprehensive Solid Waste Management Plan Cost
Assessment Questionnaire, TG-180451
Dear Ms. Morehead:
The Washington Utilities and Transportation Commission (Commission) has completed its
review of the revised cost assessment questionnaire for the draft of the King County
Comprehensive Solid Waste Management Plan (Plan), submitted May 18, 2018. Staff reviewed
this plan and the prior cost assessment questionnaire under the previous Docket, TG-180044.
The cost assessment questionnaire portion was updated at the request of Department of Ecology
due to the fact that the plan period began in 2017, which was one full year out of date when filed
with the Commission.
There was a relatively large change to the overall recycling rate in this revised cost assessment.
From 2017 to 2018, the recycling rate dropped 5.4 percent, to an overall recycling rate of 52
percent. This is due to a 14 percent increase in garbage tonnage disposed, and an 8 percent
reduction in recycling tons processed. The County proposes two tip fee increases at all King
County transfer stations during the 2018 – 2023 Plan period. These tip fee increases are expected
to occur in 2020 and 2023. As a result, there will be a rate impact to ratepayers served by
regulated solid waste collection companies in King County in years 2020 and 2023. This is
illustrated in the table shown on the following page.

The Washington State Department of Agriculture (WSDA) reviewed King County's Draft Solid Waste
Management Plan (SWMP). Our staff has determined that the draft SWMP is in compliance with state
plant pest and disease quarantines as described in Chapter 16-470 WAC. We reviewed the waste
management plan with particular emphasis to the state's apple maggot quarantine, described in Chapter
16-470-101 WAC. The transport of municipal green waste and municipal solid waste from the apple
maggot quarantine area to the pest free area is prohibited without a WSDA special permit. WSDA will
not require King County to have a special permit to ship municipal solid waste or green waste. However,
if the conditions contained in the SWMP change and you have questions about whether King County is in
compliance with the apple maggot quarantine rule please do not hesitate to contact me or WSDA Pest
Program staff.
Thank you for providing our agency with the opportunity to comment on the King County Solid Waste
Management Plan. RCW 70.95.096 requires the Washington State Department of Agriculture to review
solid waste permit applications for any increased risks of introducing a quarantine plant pest or disease
into a pest free area.

The following describes how the Plan meets these Title 10.24.30 Plan content requirements:
F.A current inventory and description of solid waste collection needs and operations within
each respective jurisdiction, which shall include:
1.Any franchise for solid waste collection granted by the utilities and transportation
commission in the respective jurisdictions including the franchise holder’s name, the business
address for the franchise, the area covered by the franchise and the rates charged in
comparison to disposal costs;
Most of the required information can be found in Appendix A – Utilities and Transportation
Commission Cost Assessment:
•Specific information regarding UTC-regulated haulers including G-certificate permit
numbers, addresses, customers served and tons collected as well as six-year
projections for both can be found on pages A-4 through A-5.
•A map, Solid Waste Collection Company Service Areas, is included on page H-6
•More general information regarding non-regulated hauler areas (cities with
contracts), including number of customers and tons collected as well as six-year
projections for both can be found on pages A-6 through A-7.
•Appendix A, pages A-2 throughA-14 provides details on the system component costs
and funding mechanisms. Pages A-13 and A-14 includes information on division
revenues and expenditures, including disposal costs.
•Attachment A includes a tariff page from each hauler serving unincorporated King
County and UTC-regulated cities for the residential curbside rate, the disposal rates,
and a link to the entire UTC franchise tariff.
•Table 4-4 on pages 4-22 and 4-23 in Chapter 4 identifies which hauler is serving
which city and unincorporated area along with other contract and collection
information.
2.Any city solid waste operational plan, including boundaries and identification of
responsibilities;
By signing the Amended and Restated Interlocal Agreement, all of the 37 cities in the King
County solid waste system have agreed that the King County Solid Waste Division is the
planning authority for the system, therefore the cities don’t have their own solid waste
plans.

3.The population density of each area serviced by a city operation or by a franchised
operation within the respective jurisdictions;
•Appendix A, page A-1, includes the population projections for the entire King County
system.
•The area served by the regional system, including cities and the unincorporated
areas, is shown in Figure 2-1, page 2-2.
•Chapter 3 discusses the current and projected population of areas served by the
transfer stations (which encompasses all of the cities and urban areas).
•The City of Enumclaw provides solid waste collection to a population of 11,490. The
City of Skykomish services a population on 200.
•Population of areas served by UTC-regulated haulers include:
Area Population
Beaux Arts 300
Black Diamond 4,335
Hunts Point 415
Kenmore 22,580
Medina 3,205
Woodinville 11,660
Yarrow Point 1,040
Unincorporated King County 245,920
4.The projected solid waste collection needs for the respective jurisdictions for the next
six years;
•Chapter 3 includes details of solid waste generation projections for the future.
•Chapter 4 discusses current and future collection issues (pages 4-21 to 4-35).
•Table 4-4, on page 4-22 and 4-23, includes information on haulers, contracts, and
collection needs/service types in each jurisdiction.
5.Analysis of operating economics, travel distances and economically optimal locations
of solid waste facilities;
Route efficiency is essential to operating economics, travel distances, and economically optimal
locations of solid waste facilities as described below:
•Chapter 5 discusses planning for the Transfer System. Figure 5-1, page 5-2, shows
where each of the transfer facilities and Cedar Hills Landfill is located. The map
shows that the facilities are well-distributed to maximize the efficiency of the
system.
•Table 5-1 lists each station and how many tons and transactions each received in
2017.

•The Plan discusses the need to site and build a new transfer station in the Northeast
part of the county, but does not identify a site.
•The Plan discusses the Level of Service criteria (including travel distance, which is an
indicator of route efficiency) and siting criteria (developed as part of the Solid Waste
Transfer and Waste Management Plan) that will be used in the siting process. These
criteria take operating economics and location into account.
•A map, Census Tract Travel Time to Nearest Solid Waste Transfer Station, included
on page H-7, shows that the travel times to the nearest station meet the Level of
Service criteria. This criterion indicates how conveniently located the facilities are for
customers (including commercial haulers concerned with maximizing route
efficiency), measured by the maximum travel time to the closest facility in their
service area. The standard was established as 30 minutes for at least 90 percent of
the customers. It provides an indication of whether the transfer stations are well
dispersed throughout the county.
G.A review of potential areas that meet the siting criteria as outlined in RCW 70.95.165.
The siting process for the NERTS has not progressed to a point where any potential sites
have been identified. A budget request to start a preliminary siting process was submitted
for Council consideration, but has not yet been approved.
•The Plan discusses the siting process (pages 5-18 through 5-20) that was used for the
South County Recycling and Transfer Station and will be adapted for NERTS.
•Action 1-t also states that the siting criteria identified in the Solid Waste Transfer
and Waste Management Plan, Appendix C, will be adapted to meet the community
needs in siting a new NERTS. Appendix C identifies the same elements to review that
are included in RCW 70.95.1.
