Current permits and actions
We are issuing a new statewide general permit for biosolids management on June 15, 2022. It goes into effect July 15, 2022. Here you can find the final permit, response to comments received on the draft permit, and other permit documents.
Current permit activities
The statewide general permit for biosolids management is how we implement the Biosolids Management rule (Chapter 173-308 WAC). The general permit contains minimum requirements that all biosolids facilities must meet, and allows us to increase environmental protections or establish more stringent biosolids management requirements for facilities on a case-by-case basis, if necessary.
The biosolids general permit is active for five years. The current permit will expire July 14, 2027.
Stay informed about a specific facility
Interested parties can comment on permit applications and proposals, but the way to comment will vary between proposals. Make one of both of the following action to ensure you are notified of permit actions and opportunities to review and provide input.
You can also write directly to a facility and request to join their interested parties list and then notify the Ecology regional biosolids coordinator who manages the facility. Be sure to keep a record of your requests.
