We invite you to comment on Draft Permit No. WA0051349.

Benton City Publicly Owned Treatment Works (POTW) has applied to renew its NPDES permit. The draft permit we propose to reissue authorizes the discharge of municipal wastewater from the POTW into the Yakima River.

Visit Water Quality Permitting and Reporting Information System (PARIS) website to view the draft permit online. 

Background

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 and meet the applicable water quality standards before it goes into surface water to protect human health and aquatic life. Learn more about water quality individual permits.
