I ANSWER OF PACIFIC GAS AND ELECTRIC COMPANY l
IN OPPOSITION TO MOTION TO COMPEL DISCOVERY l
FILED BY SAN LUIS OBISPO MOTHERS FOR PEACE DATED OCTOBER 14, 1974.
Pacific Gas and Electric Company (PGar.dE) submits that the Motion To Compel Discovery filed by the San Luis Obispo Mothers For Peace (MPP) dated October 14, 1974 should be denied.
1.
PGandE answered Interrogatory 4.
As stated in the answer, specific accidents were not the consideration in developing i
evacuation procedures.
As set forth in the 1Est sentence of the J
answer, there are no accidents which would require evacuation of the plant exclusion area.
2.
The answer to Interrogatory 57 is responsive.
If the actual frequencies are desired, PGandE hereby moves for a protective order pursuant to 10 CFR 2.740(c) that the information not be disclosed.
It involves an aspect of the plant security plan, which has been withheld from public disclosure pursuant to.10 CFR 2.790.
Also, the frequencies are irrelevant to the MFP contentions and are objected to on that ground.
3.
The answer to Interrogatory 58 reveals the only

\\
l relevant fact the question raises; namely, that the emergency
(
l channels, which are supplementary to other communication 1
facilities, are reserved for exclusive use and thus will always
)
l be available and not subject to interference through other uses.
l Again, the precise frequency is irrelevant and PGandE objects to releasing it on that ground.
If the objection is overruled PGandE hereby moves for a protective order pursuant to 10 CFR l
)
2.740(c) that the information not be disclosed for the reason outlined in paragraph 2.
4.
PGandE stands on its objection to Interrogatory 15A.
It involves matters not within the MFP petition as accepted by I
the Board for purposes of discovery.
l 5.
PGandE also stands by its objection to Interrogatory I
63.
In addition, the answer clearly calls for proprietary 1
information.
In the event the Balrd determines PGandE's objection I
is not valid, PGandE hereby moves for a protective order pursuant to 10 CFR 2.740(c) that the information not be disclosed.
Respectfully submitted, F.

Dear Mr. Parr:
Enclosed are three signed and forty conformed copies of a request dated May 25, 1976 covering extension of the completion date shown in construction permit No.
CPPR-39 from July 1, 1976 to January 1, 1977.
Kindly acknowledge receipt of the above material on the enclosed copy of this letter and return it to me in the e;telosed addressed envelope.

il Pursuant to 10 CFR 50.55(b) Pacific Gas and Electric Company (PGandE) hereby requests the Commission to extend the completion date i
I of Construction Permit No. CPPR-39 from July 1, 1976 to January 1, 1977.
l l
In an Order dated February 25, 1976 the Commission, pursuant J
f to a timely request by PGandE, extended Construction Permit No. CPPR-39 1
1 from July 1, 1975 to July 1, 1976.
Subsequently, on April 29, 1976 the United States Geological Survey (USGS) issued its review of the geologic l
and seismologic data relevant to the Diablo Canyon Units in which it was i
concluded that an earthquake occurring anywhere along the Hosgri Fault should be considered in addition to those earthquakes previously con-sidered in the design of the units.
On May 11, 197C the NRC Staff 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 plant 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
