In 2006, King County was projecting the construction of new solid waste facilities to handle increase volumes of waste as the County revamped its aging solid waste transfer system.

Lower projections for waste tonnage prompted a reevaluation of just how much expansion was needed to handle regional garbage needs, necessitating building less facilities and finding other ways to meet revised demand projections.

At its June 9 meeting, the Metropolitan King County Council accepted the report that reviewed the County’s Solid Waste Transfer and Waste Management Plan.

Adopted by the Council in 2007, the Plan approved investments for a major upgrade of the network of transfer stations (through which waste loads from cities and unincorporated areas are consolidated for transport to the Cedar Hills Landfill), to address old and outdated facilities.

“Our citizens deserve a regional solid waste system that meets service needs and protects taxpayers,” said Council Chair Larry Phillips. “Utilizing current data and actively working with regional partners helps ensure we can strike this balance.”

When adopted by the council, the plan was intended to address the potential closure of the Cedar Hills Landfill—which was expected to reach capacity and be closed by 2015— and projections that waste volumes would continue to increase significantly. Among its recommendations was the rebuilding or construction of at least two new solid waste transfer facilities to replace existing stations in northeast and east King County to handle the increased volume. Last year, the council called on the county executive to review the plan in light of reduced volume at the current facilities and significant declines in projected future volumes, as well as the closure date of the Cedar Hills Landfill being extended until at least 2025. It’s also expected that the city of Bellevue—which has historically generated 8 to 9 percent of the waste managed through the system—will leave the system in 2028.

The resulting report states that while the county needs to continue its upgrade of the transfer system, that it may not be necessary to construct a new transfer facility in northeast King County.

Further regional review will be undertaken to make a final determination, based on waste volume trends, system capacity, transactions management strategies, and related factors. The county will potentially save funds that in the original plan would have been directed toward the building of a new transfer facility in northeast King County.

The review involved collaboration between the County and the cities that contract with the County for transfer services. Meetings were held involving representatives from cities, solid waste advisory bodies, commercial haulers, local residents, and others—each had their views heard and their ideas recorded and considered.
