Request for Approval for newly developed local Industrial Pretreatment Program

Aug. 26, 2022 - Oct. 3, 2022, 11:59 p.m.

We invite you to comment on the request for approval for the newly developed local Industrial Wastewater Pretreatment Program.

The Discovery Clean Water Alliance (Alliance) has requested approval of their newly developed local Industrial Wastewater Pretreatment Program.

You can view the Interlocal Agreement, Alliance Wastewater Quality Resolution, Alliance Pretreatment Regulations, and Alliance Pretrewatment Program Manual at Alliance Industrial Pretreatment Program Delegation.


We regulate wastewater released from municipalities and industries using the National Pollutant Discharge Elimination System (NPDES) Wastewater Discharge Permit. This permit regulates wastewater that goes directly into lakes, rivers, Puget Sound, or the ocean (surface water). All wastewater must be treated before it goes into surface water to protect human health and aquatic life. Learn more about water quality individual permits.
