Reference:

1) PG&E Letter DCL-03-166, "180-Day Response to Request for Information Pursuant to Generic Letter 2003-01, 'Control Room Habitability,"' dated December 9, 2003 In reference 1, Pacific Gas and Electric Company (PG&E) committed to submit a Technical Specification (TS) change to incorporate a Control Room Integrity Program that will include periodic verification of control room inleakage within 90 days after the availability of Industry/Technical Specification Task Force (TSTF)

Traveler number TSTF-448, "Control Room Habitability," for use. The notice of availability of a TS improvement based on TSTF-448, Revision 3 to modify control room envelope habitability requirements using the consolidated line item improvement process was published in the FederalRegister on January 17, 2007.

During development of a license amendment request (LAR) based on TSTF-448, Revision 3, PG&E identified several issues that will require additional time to resolve. This letter is notification of PG&E's intent to postpone the submittal of the LAR to no later than one year from the date of publication of the notice of availability in the FederalRegister. This is consistent with the timeframe typically requested for TS changes published in the FederalRegister using the consolidated line item improvement process. This change in commitment has been discussed with Alan Wang, the NRC Project Manager for the Diablo Canyon Power Plant.
