Dear Commissioners and Staff:
On March 12, 2012, the Nuclear Regulatory Commission (NRC) issued Reference 1 to Pacific Gas and Electric Company (PG&E) directing PG&E to have a reliable indication of the water level in Diablo Canyon Power Plant's spent fuel pools (SFP).
Specific requirements are outlined in Reference 1, Attachment 2.
Pursuant to Reference 1,Section IV, Condition C, PG&E submitted its overall integrated plan (OIP) for reliable SFP instrumentation in Reference 2.
Pursuant to Reference 1,Section IV, Condition C.2, the enclosure to this letter provides PG&E's third six-month status report of its OIP. The enclosure also acknowledges the NRC's transition to an audit methodology for resolution of open or confirmatory items as described by Reference 3.

Enclosure PG&E Letter DCL-14-077 Page 1 of 4 Pacific Gas and Electric Company's Third Six-Month Status Report for the Implementation of Order EA-12-051 1 Introduction Pacific Gas and Electric Company (PG&E) developed an overall integrated plan (OIP)
(Reference 1 [Refer to Section 9 of this enclosure for a list of references.]), to achieve compliance with the requirements described in NRC Order EA-12-051 (Reference 2), . This enclosure provides the third update of milestone accomplishments since submittal of Reference 1, including any changes to the compliance method, schedule, or need for relief and the basis, if any. This enclosure also provides an update to the status of responses to requests for additional information (RAis) provided in Reference 3 and PG&E's responses to Reference 4.
2 Milestone Accomplishments No milestones have been completed since the submittal of Reference 8, and are current as of July 31, 2014:
3 Milestone Schedule Status The following table provides an update to the milestone schedule. It provides the activity status of each item, and whether the expected completion date has changed.
The dates are subject to change as design and implementation details are developed.
The target completion dates for developing the Unit 1 and Unit 2 design have been updated to reflect the current design schedule. The revised milestone completion dates do not impact the order implementation date.
Original Target Target Activity Completion Milestone Completion Status Date Date Changes Submit 60-day progress report 10/2012 Complete Submit overall integrated plan 2/2013 Complete Submit six-month updates Update 1 8/2013 Complete Update 2 2/2014 Complete Update 3 8/2014 Complete Update 4 2/2015 Not started Update 5 8/2015 Not started Update 6 2/2016 Not started Update 7 8/2016 Not started

No relief is being requested at this time.
6 Open Items from Overall Integrated Plan None 7 Open Items and Responses to Requests for Additional Information PG&E submitted DCL-13-073 (Reference 3) in response to an NRC RAI (Reference 6).
In its response, PG&E committed to provide a status update of the information necessary to complete its response to the RAis.
Enclosure PG&E Letter DCL-14-077 Page 3 of 4 The NRC's Interim Staff Evaluation (ISE) (Reference 4) requested PG&E to provide responses to RAis in the six-month status updates as they become available, but no later than April 30, 2015.
Finally, an NRC Letter (Reference 9) announced the NRC's transition to an audit based review process of utility responses to Order EA-12-051. In addition to announcing the transition to an audit based review process, the audit plan also notified each licensee participating in the audit not to formally submit their RAI responses on the docket but instead, put their responses and any other supporting information on their ePortals by the date identified in their ISE to support the Staff's review process. PG&E will provide a status of the remaining Open Items and responses to RAis, described in Reference 8, as they become available, but no later than April 30, 2015.
