Dear Sir or Madam,
By Reference 1 the Nuclear Regulatory Commission (NRC) 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 ofa 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 NRC Order EA-13-109. Reference 4 reported the completion of activities associated with NRC Order EA-12-049 as well as Phase 1 of NRC 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 May 31, 2019 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. This letter will serve as the final 6-month update required by Reference 1 prior to the submittal of the required report of full compliance with Reference 1.
No new commitments are being made by this letter or the attachment. 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 23/thday of Tur1 e ,2019.

GO2-19-082 Page 1 of 10 Attachment 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.

No new equipment was procured for Phase 2. Therefore, no new maintenance procedures are required.
4.0 Changes/Updates to Overall Integrated Plan Changes have been made to the response sequence used for mitigation of a beyond-design-basis accident to enable the use of a single response to both a non-severe and severe accident scenario. The changes have been revalidated and remain within the original staffing study staffing levels.
Upon completion of the updated validation, an integrated review was conducted to ensure that adequate resources (personnel, equipment, materials) are available to implement the individual strategies to achieve the intended results was conducted. A comparison of the original FLEX Integrated Review and the severe accident response was made. The review of the two responses shows that there are adequate on-shift crew resources, supplemented by returning staff (after 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />) without any overlap of assignments to complete the required actions in the required time. The integrated reviews are provided at the end of this attachment.

Additionally, the sound powered phone system and radio system are routinely tested and inventoried.
