City of Chelan Draft Permit

We invite you to comment on Draft Permit No. WA0020605.

The City of Chelan's Publicly Owned Treatment Works (POTW) has applied to renew its NPDES permit. The draft permit we propose to reissue authorizes the discharge of treated domestic wastewater from the POTW into the Columbia River.

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.
