King County solid waste facilities are intended to serve King County residents and businesses located within the borders of King County with the exception of the Cities of Seattle and Milton. Waste from outside the County’s jurisdiction is not accepted without written authorization and proof of release from the jurisdiction of origin.

The Solid Waste Division (SWD) accepts waste at King County facilities in accordance with the county's waste acceptance rule. This rule restricts or prohibits the disposal of some types of waste due to regulatory or operating constraints or environmental or public health concerns, or because the waste can readily be recycled or disposed more appropriately at a different type of facility.

Some restricted wastes may be accepted for disposal only when specific conditions are met before or during disposal. The process that has been established for evaluating restricted wastes, determining whether they can be accepted, and establishing the conditions for acceptance is known as waste clearance. For more information, please see the complete waste clearance policyDownload PDF 150 K.

Determining if wastes can be disposed at county facilities

To determine if a material can be disposed, refer to the What do I do with...? site. Select the material to be disposed to find the waste disposal information. Contact SWD if your waste does not appear on the list or if you have questions about acceptance of your waste.

If a waste clearance is required, you will need to fill out one of the following forms:

Based on the information submitted, SWD will issue a waste clearance decision if the waste in question can be disposed at a county facility. The waste clearance decision describes where the waste may be disposed and any conditions that must be met. You must take a copy of the waste clearance decision with you when you dispose your waste.

A special waste rate is applied to materials that require special handling, recordkeeping or review. The rate to be applied (basic rate or special waste rate) is indicated on the waste clearance decision.

For additional information, please contact SWD at 206-477-4466. To find out more about the types of materials accepted and not accepted at the county's transfer stations, please refer to the county's waste acceptance rule.
