Energy Northwest; Columbia Generating Station

The U.S. Nuclear Regulatory Commission (NRC) is considering issuance of an amendment to Renewed Facility Operating License No. NPF- 21, issued on May 22, 2012, and held by Energy Northwest (the licensee) for the operation of Columbia Generating Station (Columbia), located in Benton County, Washington. The proposed amendment would revise the Environmental Protection Plan (Non-Radiological) (EPP), contained in Appendix B to the Columbia renewed facility operating license. The NRC is issuing a final environmental assessment (EA) and finding of no significant impact (FONSI) associated with the proposed license amendment.
