We invite you to comment on draft water quality permit no. WA0022667
The draft permit we proposed to reissue to the town of Cathlamet Wastewater Treatment Plant authorizes the discharge of domestic wastewater into the Cathlamet Channel of the Columbia River.
You can view the documents at Cathlamet STP or visit the Water Quality Permitting and Reporting Information System (PARIS) website.
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.
