'# s PACIFIC GAS AND ELECTRIC COMPANY (DI ABL,0 CANYON NUCLEAR P0nER PLANI, UNIT I)

DOCKET NO. 50-275  ;

ORDER EXTENDING CONSTRUCTION COMPLETION DATE Pacific Gas and Electric Company is the holder of Construction Permit i

CPPR-39 issued by the Nuclear Regulatory Commission on April 23, 1968 l for construction of the Olablo Canyon Nuclear Power Plant, Unit I, presently under construction on the applicant's si te in San Luis Obispo

/

County, Cal i fornia .

On May 25,1976, Pacific Gas and Electric Company filed a request for an extension of the completion date.  ;

On Apr i l 29, 1976 the United States Ceologice! Survey (USGS) issued its review of the geological and seismologic data' relevant to the Diablo <

I Canyon Units in which it was concl uded that an earthquake occurring anywhere j along the Hosgri Fault should be considered in addition to those earthquakes previousl y conoidered in the design of the units. On-May 11, 1976 the Commission's Staf f issued Supplement No. 4 to the Safety Evaluation Report which specified an ef fective horizontal ground acceleration to be used for the development of design response spectra for the piant based upon the earthquake postulated by the USGS.

Additional time will be required to permit PGandE to evaluate the plant's capability to withstand the new earthquake, for the Commission to review and eval uate PGandE's work, and to concl ude the licensing process.
