WfP-2 SCHEDUI.E On February 10, 1982 we had an extensive meeting with the Wi!p-2 and Skagit applicants to discuss open issues in the Geosciences area. Although the discussions were very pointed and some new information was presented, resolution of the three primary issues was not reached. After a caticus of the I;RC staff, USGS and our consultant Dr. Sicamons, the app.licant was advised of the following ninimum requests for information.

. address itaxie Valley /uenas Valley Holocene (7) faults
. clarify segnentation argunents
. address Cochran report
, address fib end of Cold Creek lineaxnt across Untanun 'itn.
2.
Southeast Anticline Fault
. provice a series of core boring (2 lines) to deoonstrate strike, dip, and extent of fault.
reexamine geophysical data across fault and extend coverage provide age dating of possible capping material possibility of geophysical lines on strike oneestt side of river 3.
roar.d l'otier
. Providt report on 193G earthquake Magnitude reinterpretation chancing from 6.1 to 5.7(?).
clear up conflict of association of 1936 EQ with structure or not.
. provide report on high shear wave velocity contrast for site specific spectra.
provide assessment of impact of new ragnitude on site specific spectra.
4.
U.S.G.S.
. one question also related to origin of Southeast l'tn. Anticline
. possible slight exceedance of design ground motion may need sone resolution
.,their letter to us pends further geoloqic resolution, although a status can be available in 1-2 weeks identifying open issues.
