UNITED STATSS OF AMERICA L ATOMIC EilEEGY COMMISSION In the Matter of f F3CIFIC GAS nLo ELCCTRIC COMPAhY Docket No. 50-323 (Diablo Canyon Unit 2)

)

SUPPLEMEliTAL REPLY TO PACI?IC 2S FINDINGS OF FACT AND CONCLUSIONS OF IAW These brief comments are a supplement to the " Reply to the September 4,1970 statement of Mr Phillip Crane of PG&E by Ralph Vrana,"

(1) Finding No. 9 (p, h) and subsequent findings are tentative, negative , and inconclusive., With respect to an issue of this t.agnitude involving a facility with potential for releasing radio- ,

active wastes over a wide area in the event of an earthquake disaster, Pacific has a positive responsibi?.ity to examine strong evidence presented in this case by Scenic Shoreline and to provide assurance j that all earthquake evidence has been S iven the most careful scrutiny.

l (2) Finding 13 (p. 6) There is no clear evidence that the Edna Pault was taken into consideration in the original plant studies. Maps and research accounts have not been produced on the record to document Pacific's claim that this fault was considered. The decision of $taff to study the Edna Pault and the For.r d to schedule a hearing on this and associated faults is strong indication thet these 6eolo61 cal features were not taken into account. T/ja further claim that the 8708100366 870729 PDR FOIA PDR CONNORB7-214

2 Edna ran11: bas not beer. act3.v2 within et least the last 100,000 years has not been substantiated.

In correspondence (January 22, 1970) to Ralph Vrana, earlier brought to the attentien of the Board and the U. S. Geological Survey, (February 27, 1970), clarence A. Hall, Jr., professor of

! geology at UCL/. , writes: "The most recent movement along this fault (Edna Fault zone) is since the Pleistocene," In other words,  !

according to Hall, the activity has been less than 10,000 years ago, j

)

and conceivably at a auch more recent date. The Edna Fault zone Hall said "oc joins the West Huasna fault in the Niposo quadrangle and j l

apparently gces out to sca south of Les Osos and near Montana de Oro State Park "

It should be noted, too that Mr. Crane:s reference to the' ,

1 difficulty of 1ccating epicenters accurately, his reference to the i 1

" doubtful ve.11dity" cf e zoccieting certain apicenters with a fea-ture such as ths Ednc Fault t rai se significant questions as to the actual placeacnt of the epicenters cited. Dr. Devine (tc, p. 45) observes "I ccn cLmsent though, that even well-recorded epicenters, ,

well-recorded events, the apicenters can have variations of several miles. The standard one has inherent in it,n maximum variation of up to 13 miles " Such a variation could put an occurrence under the Diablo cite i tself in spite of the evidence of no observable sura ,

face expreccion in that immediate area.

(3) Finding 15 (p. 7). Pacific argues that it "does not bon ~

cede' that such a 'fsult i (Los Osos) exists." The chief Pacific ex-perts also concede they have not been out in the field with Mr. Vrana

- -to examine this fault. Until every positive step is taken to he sure

of the earthqua,:c. situation in the Port San Luis Quadrangle r an adequate decisien on the Diablo issue cannoc be reached, '

(4) Findir.g 16 (p. 8), The combined ' ele st Huasna, Edna, and Los Osos faults sight well exceed 40 miles. The potential earth-quake magni.lude generated at such a structure could exceed the
