1. Letter GO2-16-046 from A. L. Javorik (Energy Northwest) to NRC:

"License Amendment Request to Modify Technical Specification Surveillance Requirement (SR) 3.4.3.1 and SR 3.4.4.1 Safety/Relief Valves (SRVs) Setpoint Lower Tolerance," dated May 10, 2016 (ADAMS Accession No. ML16131A891)

2. Letter from L. John Klos (NRC) to M. E. Reddemann (Energy Northwest):

"Columbia Generating Station - Issuance of Amendment RE: Adoption of Technical Specification Task Force traveler TSTF-425, Revision 3 (CAC No. MF6042)," dated November 3, 2016 (ADAMS Accession No. ML16253A025)

Dear Sir or Madam:

By letter dated May 10, 2016 (Reference 1), Energy Northwest submitted a license amendment request (LAR), to modify Technical Specification (TS) Surveillance Requirement (SR) 3.4.3.1 and SR 3.4.4.1 Safety/Relief Valves (SRVs) Setpoint Lower Tolerance. Subsequent to submitting this LAR, Energy Northwest received amendment 238 (Reference 2) to Columbia's operating license and TS which moved certain surveillance requirement (SR) frequencies to an owner controlled Surveillance Frequency Control Program (SFCP).

Amendment 238 (Reference 2) has affected the TS pages which contain SR 3.4.3.1 and 3.4.4.1. This supplement provides the markups and clean pages for SR 3.4.3.1 and 3.4.4.1 in Attachments 1 and 2 respectively.

G02-17-027 Page 2of2 The No Significant Hazards Consideration Determination (NSHCD) provided in the original submittal is not altered by this submittal.

This letter and its attachments contain no regulatory commitments. If you should have any questions regarding this submittal, please contact Mr. R. M. Garcia, (509) 377-8463.

I declare ynder penalty of perjury that the foregoing is true and correct. Executed on 3/s[
