Dear Sir or Madam:

By letter dated March 3, 2016 (Reference 1), Energy Northwest submitted a license amendment request (LAR), to adopt TSTF-522 Revision 0, for Columbia Generating Station (Columbia) to revise the technical specification (TS) requirements to operate ventilation systems with charcoal filters for 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> each month.
