- John, We would like to formally request additional time to submit the response to the SRXB questions below. Our ability to deliver these responses by the current January 5th due date has been challenged due to a forced plant outage and recovery resulting from a weather related load reject as well as reduced work hours due to adverse weather conditions.
A revised due date of January 13, 2017 is requested. Thanks, Rick Garcia Licensing Energy Northwest - Columbia Tel 509-377-8463 Fax 509-377-4317 From: Klos, John [1]

Dear Mr. Garcia,
By letter dated June 28, 2016, (Agencywide Documents Access and Management System (ADAMS) Accession No. ML16183A365), as supplemented by letter dated August 18, 2016 (ADAMS Accession No. ML16231A511), Energy Northwest submitted a license amendment for Columbia Generating Station (CGS). The proposed amendment would revise the operating license and technical specifications to implement an increase in rated thermal power from the current licenses thermal power of 3486 megawatts thermal (MWt) to a measurement uncertainty recapture thermal power of 3544 MWt.
The U.S. Nuclear Regulatory Commission (NRC) staff, specifically the Reactor Systems Branch (SRXB) in the Office of Nuclear Reactor Regulation, has reviewed the submittal and determined that the attached NON - proprietary requests 1
for additional information (RAIs) are needed to complete its technical review and make a regulatory finding regarding this license amendment request.
Please see the formal RAIs below. A clarification call was held on November 16, 2016 to ensure your staff understood the RAIs. In the clarification call, Energy Northwest agreed to submit the response to the RAIs by Thursday Jan 5, 2017.
