'L. Manning Muntzing, Director of Regulation SEISMIC AND G20 LOGIC SITING CRITERIA FOR NUCLIAR 20WFR PLANTS The seismic and' geologic criteria for" evaluation of proposei nuclear sites are set forth in a proposed Appendix A to 10 CFR 100, issued for cc enn November 16, 1971.
These criteria, in defining an
" active fcult," group Puerto Rico in the same category o

MorecVer, I am not aware of any fault en the island of Puerto Rico tha:

It is not unreasonable to e::pect that the inclusion of Puer:o Rico with areas cf recorded surface displace =en:
might influence reviewers in applying the criteria'to seismological and geological studies.! For example, it is my understanding that U.S. Geological Survey has indicated that.it is necessary to prove "beycnd a reasonable doubt" with regard to demonstrating geologic
. inactivity > of a site in Puerto Rico.
This would seem to place a burden *of proof on an applicant that goes
. beyond the language of tha proposed criteria'.

It is =v understan' ing that the major pur:ose of that-d part of the critoria was to distinguish between Eas
'Ceast and West Coast seismic conditions.
I would appreciate your vieus en the possibility of =cdifying
- the propcsed criteria to include a third category of seismic activity for creas such as puerto Rico.
