2019 Comprehensive Solid Waste Management Plan
The Washington State Department of Ecology approved King County's 2019 Comprehensive Solid Waste Management Plan Download PDF 16 MB (Plan) on Nov. 14, 2019. The Plan had already been approved by the King County Council and 24 of King County's 37 partnering cities. City approval of the 2019 Plan required approval by cities representing three-quarters of the total population of the cities that acted on the Plan during the 120-day period. The 24 cities that approved the Plan represent 92 percent of the population of the cities that took action during the city approval period.
The Final Environmental Impact Statement (EIS) was developed in accordance with the State Environmental Policy Act. The Final EIS evaluates the potential significant environmental impacts of the facilities, programs, and services described in the Plan, which presents strategies for managing King County's solid waste over the next six years, with consideration of the next 20 years. It also describes mitigation measures that can be used to avoid such impacts or reduce them below significant levels; and, where possible, draws conclusions about whether there may be any significant unavoidable adverse impacts of several project and program alternatives described in the Plan.

Washington State law requires that each county, in cooperation with the cities located in the county, prepare a coordinated, comprehensive solid waste management plan (Plan) as outlined in RCW 70.95.080. The previous Plan, the 2001 Comprehensive Solid Waste Management Plan, along with a State Environmental Policy Act (SEPA) non-project Environmental Impact Statement (EIS) that addressed the potential impacts of implementing the plan, was adopted in 2001. Actions taken by the Division since then to update the 2001 Plan include:
- In 2005, the Division, in collaboration with the cities, began preparation of the 2007 Transfer and Waste Management Plan (Transfer Plan), as well as preparation of a SEPA EIS that supplemented the 2001 Plan’s EIS. The County Council adopted the Transfer Plan in 2007; and
- In 2011, along with a SEPA Determination of Non-Significance (DNS), and in 2013 the 2001 Plan was reviewed and updated. However, these reviews were not formally adopted by the King County Council or by the cities.
The Division has worked with cities to update the 2001 Plan. A new 2019 Plan presents strategies for managing King County's solid waste over the next 6 years, with consideration of the next 20 years. It also includes policies, recommendations, and goals for: solid waste system planning; waste prevention, recycling, and solid waste collection; solid waste transfer and processing system; landfill management and solid waste disposal; and solid waste system finance.
The Plan incorporates a number of policy and program changes, including:
- A reevaluation of the 2007 Transfer Plan
- Recommendations from the Division's Sustainable Solid Waste Management Plan to study options for resource recovery and potential changes to the solid waste rate structure
- Possible policy changes such as instituting mandatory recycling requirements, a new 70% recycling goal, and new construction and demolition debris recycling and disposal policies
- Consideration of anaerobic digestion (AD) and advanced materials recovery (AMR) processing as possible transfer/processing options
- Extending the life of Cedar Hills Regional Landfill by optimizing development of the site for landfilling. View an infographic of the landfill Download PDF 800 K.
- Consideration of waste-to-energy and other alternative conversion technologies as long-term disposal options, in addition to waste export, and partial early export
The Division has been working with its advisory committees, the Metropolitan Solid Waste Management Advisory Committee and the Solid Waste Advisory Committee on the new Plan.
