NPDES Permit Program and Annual Report

To conform with regulations of the Federal Clean Water Act (CWA), municipalities are required to comply with a National Pollutant Discharge Elimination System (NPDES) permit. This federal permit regulates wastewater and stormwater that is discharged into U.S. waters and waters of the state, including rivers, lakes, streams, and all underground waters and aquifers.

The Washington State Department of Ecology (Ecology) is the regulatory authority for the NPDES permit. Ecology issued the most recent NPDES Phase II Municipal Stormwater Permit for Western Washington in August 2019, this permit will cover the period from 2019-2024.  Please contact Stormwater Engineering Staff if you have any questions or comments regarding our SWMPP, the annual report responses, or attachments.
