December 11, 2012 by Electronic Information Exchange Administrative Judge Alex S. Karlin Administrative Judge Nicholas G. Trikouros Administrative Judge Paul B. Abramson Atomic Safety and Licensing Board Panel U.S. Nuclear Regulatory Commission Two White Flint North 11545 Rockville Pike Mail Stop: T-3F23 Rockville, MD 20852 In the Matter of PACIFIC GAS AND ELECTRIC COMPANY (Diablo Canyon Power Plant, Units 1 and 2)

Docket Nos. 50-275-LR and 50-323-LR RE: Status Report

Dear Administrative Judges:

As directed by the Licensing Board Order of June 7, 2011, Pacific Gas and Electric Company (PG&E) hereby provides its monthly report specifying its current best estimate of the dates on which it expects to complete milestones related to 3D seismic studies for Diablo Canyon Power Plant (DCPP) and the coastal zone consistency certification associated with NRC license renewal for DCPP.

The schedule for implementation of the seismic studies has changed since PG&Es last submittal on November 13, 2012. The California Coastal Commission decided on November 14, 2012 to deny PG&Es permit application for certain 3D High Energy Marine Studies, and does not appear likely to support high energy seismic research. Accordingly, PG&E will not complete the Phase 1 and Phase 2 high energy surveys previously shown on the schedule. Instead PG&E will be conducting a thorough evaluation of the available seismic data, including the data collected from the recently completed advanced onshore and low energy offshore studies. The revised schedule incorporates a new milestone for this evaluation, by which PG&E will determine whether and how to proceed with any additional seismic data collection. Other dates have been adjusted accordingly.

PG&E appreciates that, in the absence of definite dates for completing the milestones related to the seismic studies, the Licensing Board is unable to establish a meaningful adjudicatory schedule pursuant to 10 C.F.R. § 2.332(c). For this reason, PG&E will continue to provide specific dates in the monthly reports to the extent practicable, recognizing that these dates may be modified as more accurate information becomes available.

DC:720421.3

PG&E wishes to assure the Licensing Board that it is making every effort to minimize the extent of the delay in the NRC license renewal process.

Executed in accord with 10 CFR 2.304(d),
