FACILITY: WPPSS NUCLEAR PRELIECTS NO. 3 AND NO. S APPLICANT: NA211NGTON PUBLIC POWER SUPPLY SYSTEM Sule4ARY OF MEETING WITH APPLICANT ON OCTOBER 29, 1974 REGARDING SIDPE STABILITY On October 29, 1974, representatives of WPPSS, Ebasco, and Woodward-Lundgren met with the Regulatory staff in Bethesda. WPPSS had re-quested the meeting to allow their geologic consultant to present additional information regarding slope stability and landslides in the site area. A list of attendees is contained in Enclosure No. 1.

Woodward-Lundgren explained the slope stability analysis described in Section 2.5 of the PSAR. We commented that the figures in the PSAR in the slope stability subsection are not clear. As a result, we have not been able to identify the steepest slopes on these figures. We stated that the conclusions about the origin of land-slides that have occurred in the site vicinity should be given more support. This will require additional field work.

At hPPS$' request, we clarified the following questions in our October 11, 1974 request for additional information: 323.1, 323.6, 323.8, 323.10 and 323.12.

No new inforvaation on slope stability and landslides was presented.
