Information, including analyses and substantiation, must be presented in the appli-cant's safety analysis report (SAR) and reviewed by the staff concerning the sta-bility of all earth and rock slopes both natural and man-made (cuts, fills, embank-ients, dams, etc.) whose failure, under any of the conditions to which they could be exposed during the life of the plant, could adversely affect the safety of the plant. The following subjects must be evaluated using the applicant's data in the SAR and information available from other sources: slope characteristics (subsection 2.5.5.1); design criteria and design analyses (subsection 2.5.5.2); results of the investigations including borings, shafts, pits, trenches, and laboratory tests (subsection 2.5.5.3); properties of borrow material, compaction and excavation speci-fications (subsection 2.5.5.4). The HGEB will coordinate other branch evaluations that interface with the Geotech-nical Engineering aspects of the site as follows: Geosciences Branch (GB) will determine the adequacy of the geologic and seismic information cited in support of the applicant's conclusions concerning the suitability of the plant site and the stability of earth and rock slopes as part of its primary review responsibility for SRP Section 2.5.1. GB also reviews the seismological and geological investigations carried out to establish the ground motion environment for seismic design of the plant, the procedures and analysis used by the applicant in establishing the SSE and OBE for the site, and the seismic design bases for foundations as part of its primary review responsibility for SRP Section 2.5.2. The results of the stability evaluations of earth and rock slopes are reviewed by Structural Engineering Branch (SEB) to assure that displacements or failure of site slopes as indicated in the SAR do not have an adverse impact on structural components as part of its primary review responsibilities for SRP Sections 3.7 and 3;8
