Proposed National Pollutant Discharge Elimination System (NPDES) Permit Reissuance


The Washington State Energy Facility Site Evaluation Council has received an application from Energy Northwest for reissuance of NPDES Permit No. WA-002515-1, for the Columbia Generating Station.

NPDES Permit WA-002515-1 is a wastewater discharge permit for the Energy Northwest Columbia Generating Station located on the U.S. Department of Energy's Hanford Site. Columbia Generating Station is a boiling water nuclear power reactor that has been in commercial operation since 1984. The plant discharges to the Columbia River at Outfall 001. This reissuance also authorizes discharges to ground of process wastewater at Outfall 002 until the completion of Energy Northwest's evaporation pond, which is anticipated to occur by July, 2014. The draft permit also removes Energy Northwest's authorization to discharge process wastewater to ground from Outfall 003.

Tentative Determination to Reissue Permit

A tentative determination has been made to reissue the National Pollutant Discharge Elimination System (NPDES) Permit, No. WA-002515-1, for the Energy Northwest Columbia Generating Station (formerly WNP-2) for a period of five years beginning from the date of final adoption, subject to appropriate changes or adjustments as may result from public comments, the public hearing record, or the U.S. Environmental Protection Agency (EPA) review. The tentative determination is based on a draft permit that sets forth the 1) proposed effluent limitations; 2) schedules of compliance; and 3) other terms and special conditions. Details about this determination are contained in a fact sheet describing the permit conditions and any changes proposed for this facility.
