August 18, 1981 MEMORANDUM During the evidentiary hearing session on August 13, 1981,- the Board approved 3 hearing schedule under which the seismic criteria for the Midiland site are to be considered beginning October. 13, 1981 (Tr. 4335).
Prepared testimony is to be. filed at least two weeks earlier--i.e_., by September 29, 1981 (Tr. 4336).
It ir our understanding that the Appficant will elect one of the two alternatives for selection of the Safe Shutdown Earthquake-(SSE) and I
associated ground acceleration suggested in the letter dated October 14, 1980 from Robert L.- Tedesco (NRC) to J. W. Cook of Consumers Power Co.,
titled " Seismological Inp;t for the Midland Site." The first alternative is
= apparently based on a deterministic aoplication of 10 CFR Part 100, Appendix
'A (utilizing the standardized response spectra of Regulatory Guide 1.60 anchored'at 0.19 ).
The second appears to be a probabilistic approach which 9
3 utilizes' site specific response spectra.
