EPA is proposing to issue National Pollutant Discharge Elimination System (NPDES) permits for four hydroelectric generating facilities on the lower Columbia River operated by the United States Army Corps of Engineers:
- Bonneville Project (WA0026778).
- The Dalles Lock and Dam (WA0026701).
- John Day Project (WA0026832).
- McNary Lock and Dam (WA0026824).
These permits will address oil and grease discharges, pH, and cooling water discharges from hydroelectric generating facilities.
The Region 10 office of the EPA has tentatively determined to issue discharge permits to the applicants.
Water Quality Certification
EPA requested final 401 certification from the Washington Department of Ecology on March 18, 2020.
Electronic copies of the draft permits and technical fact sheet are available below under "Related Documents."
Copies and other information may be also requested by contacting Jennifer Wu (email@example.com), 206-553-6328.
Because of COVID-19 response, there is no public access to the Region 10 EPA building at this time. Therefore, we cannot make hard copies available for viewing at our offices.
