July 10, 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&E's last submittal on June 12, 2012. PG&E has revised the Ocean Bottom Seismometer (OBS) Study schedule to allow for various agencies to complete required actions prior to issuing the OBS permits. PG&E has revised the schedule for completion of the NRC's review of the Shoreline Fault Report based on status discussions with the NRR Project Manager.

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.

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. For example, PG&E is working with the relevant State and federal agencies to accelerate efforts to obtain permits needed to complete the 3D seismic studies.

While PG&E expects the seismic studies to be completed and a report issued no later than December 2015, any actual delay to this proceeding may be less than the 52 months referenced in the June 7, 2011 Order.

Executed in accord with 10 CFR 2.304(d),
