Subject:

COLUMBIA GENERATING STATION, DOCKET NO. 50-397 2019 ANNUAL ENVIRONMENTAL OPERATING REPORT

Dear Sir or Madam:

This letter is submitted pursuant to Section 5.4.1 of the Columbia Generating Station Environmental Protection Plan (EPP), Appendix B to the Facility Operating License No.

NPF-21, which requires Energy Northwest (EN) to submit an Annual Operating Report for the EPP to the Nuclear Regulatory Commission (NRC) for the prior calendar year.

Through this letter, EN is notifying NRC of one nonconformance to the EPP in 2019. A 2019 nonconformance occurred when EN failed to submit a copy of the modified National Pollutant Discharge Elimination System permit within 30 days of the issued date of March 19, 2019, pursuant to Section 3.2 of the EPP. This was entered into the Corrective Action Program on April 25, 2019, for resolution (CR #392585). The conformance resolution was submitted in letter GO2-19-076 (ML19120A483).

No other non-routine, non-radiological reports were required for 2019 as there were no changes in station design or operation, testing, or experiments that involved an unreviewed environmental question. A summary of the effluent data reported to the State of Washington Department of Health and the Energy Facility Site Evaluation Council on the monthly discharge monitoring reports are provided in the Attachment.
