==Dear Sir or Madam,==

By Reference 1 the Nuclear Regulatory Commission (NRG) issued Order EA-13-109 which required licensees to develop an overall integrated plan (OIP) and submit 6-month update reports in regards to installation and operation of a reliable hardened containment vent capable of operation under severe accident conditions. Reference 2 provided the Columbia Generating Station's revised OIP for Phase 1 of Order EA  109 and the initial OIP for Phase 2 of the Order. Reference 3 transmitted the previous 6-month update report for Phase 2 of NRG Order EA-13-109. Reference 4 reported the completion of activities associated with NRG Order EA-12-049 as well as Phase 1 of NRG Order EA-13-109.
The attachment to this letter provides the required 6-month update report for the remaining Phase 2 activities and open items of Order EA-13-109 as of November 30, 2018 including the Phase 2 request for additional information identified in Reference 5 relating to Columbia's overall integrated plan for severe accident capable hardened vents.
No new commitments are being made by this letter or the enclosure. If you have any questions or require additional information, please contact Ms. D. M. Wolfgramm at (509) 377-4792.
I declare under penalty of perjury that the foregoing is true and correct.
Executed on this    f!/t"- day of /lee< ,rz~ ~ f' , 2018.

GO2-18-145 Attachment Page 1 of 4 1.0     Introduction By Reference 1, the Nuclear Regulatory Commission (NRC) issued Order EA-13-109 to Columbia Generating Station (Columbia). The Order contained requirements for the installation of a reliable containment hardened vent capable of operation under severe accident conditions. Reference 1 also required submittal of an Overall Integrated Plan (OIP) describing how compliance with the requirements described in the Order will be achieved and required the submittal of status reports at six month intervals. This attachment provides Energy Northwests six-month status report for the remaining Phase 2 milestones, open items, and any changes to the compliance method or schedule.
