Dear Commissioners and Staff:

Pursuant to 10 CFR 50.90, Pacific Gas and Electric Company (PG&E) submitted an application for amendment to Facility Operating License Nos. DPR-80 and DPR-82 by PG&E Letter DCL-11-072, "License Amendment Request 11-06, Revision to Technical Specification 3.3.5, 'Loss of Power (LOP) Diesel Generator (DG) Start Instrumentation,'" dated October 24,2011. PG&E Letter DCL-11-072 submitted for Nuclear Regulatory Commission (NRC) review and approval proposed to revise Technical Specification (TS) 3.3.5, "Loss of Power (LOP) Diesel Generator (DG)

Start Instrumentation," revise Final Safety Analysis Report Update (FSARU)

Appendix 6.20 and Sections 6.3, 15.3, and 15.4, revise the loss-of-coolant accident control room operator and offsite do~e analysis of record described in the FSARU, and provide a new process for revising input values to this analysis.

In PG&E letter DCL-11-072, PG&E requested that the license amendments be made effective upon NRC issuance, to be implemented during Unit 2 Refueling Outage 17 and Unit 1 Refueling Outage 18. To facilitate the actions required to implement the license amendments, PG&E requests that the implementation schedule be changed to "during Unit 1 Refueling Outage 18 and Unit 2 Refueling Outage 18."

If you have any questions or require additional information, please contact Mr. Tom Baldwin at (805) 545-4720.
