Dear Dick:
PDR hA/,7 As requested, I met with NRC, USGS, and GE representatives at the Vallecitos Nuclear Facility on 8-24, in company with Ben Page.
Proposals for trenching, possibly seismic profiling, and possibly drilling to resolve questions about faults and land-slides were discussed in depth. These plans are well thought out an'd hdyc a good chance of resolving the prob 1 cms.
It was a productive meeting, although no final conclusions can be drawn.
I'd like to reserve further comments pending rcccipt of the,back-Bround geologic material.
Ben and I also spent a couple of hours in the field looking at rock exposures, examin.ng the evidence regarding faulting, and sccing how the proposed trenches may pi down the questions.
f Sincerely,
/2 (, \\ y4 db'A '(f p /' George A. Thompson Professor of Geophysics GAT /md. 78M.C?. o 3/ 3 l l .}}
