SEPA appeal process - Wastewater Treatment and Solid Waste Divisions

The Wastewater Treatment Division and the Solid Waste Division have established a process for appeals to any Determination of Non-significance (DNS) or Final Environmental Impact Statement (Final EIS) issued under the State Environmental Policy Act, or SEPA.

The divisions are lead agencies under SEPA, which means that they are responsible for complying with SEPA's procedural requirements with regard to that division's issuance of a DNS or Final EIS.

This webpage provides basic information and a summary of the steps of the appeal process. More information about this process is found in the Public Rule PUT 7-4-1 which details the appeal process and should be referred to by anyone who is considering initiating the appeal process.


This process offers a timely and fair resolution of disputes. It is less formal and, in many cases, less expensive than appeals that go directly to court, while providing a comprehensive review of the issues being raised in the appeal.

Appeals must be filed within a specific time period after a DNS or Final EIS is issued. From that point, the administrative process provides for up to ninety (90) days for a decision on the appeal. In some cases, the timeline can be extended for more complex projects.

The appeal is heard by the King County Hearing Examiner. The hearing examiner is appointed to conduct quasi-judicial hearings on a range of actions. In addition to the appeals covered here, other applications heard by the hearing examiner include rezones, preliminary plats, and other land use actions. The hearing examiner is a professionally-trained person making objective decisions that are supported by a record of the proceedings.

Refer to the Public Rule for more information on appeal procedures and details.
