ponsibility for SRP Section 2.3.6 (proposed).7 2. The Geosciences Branch (GB)ECGB will determines the adequacy of the 8 geologic and seismic information cited in support of the applicant's conclusions concerning the suitability of the plant site as part of its primary review responsibility for SRP Section 2.5.1. 3. GB alsoECGB reviews the seismological and geological investigations carried 9 out to establish the ground motion environment for seismic design of the plant, the procedures and analyses 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. 4. HGEBECGB reviews the geotechnical parameters and methods employed in the 10 analysis of soil and foundation response to the ground motion environment. The results of the stability evaluations of subsurface materials and foundations are reviewed by SEB to assureensure that the soil loads and structural deflections, including any 11 reduction in support capability of subsurface materials, can safely be accommodated by structural components as part of its primary review responsibilities for SRP Sections 3.7 and 3.8. The HGEBECGB will coordinate other branch evaluations that interface with the Geotechnical 12 Engineering aspects of the site as follows: 1. Licensing Guidance Branch (LGB)The Technical Specifications Branch (TSB)13 will coordinate the review of technical specifications to insureensure that geotechnical engineering design features related to materials of construction and geometric arrangement of subsurface materials, foundations, cut slopes, and embankments, which if degraded or altered would have a significant effect on safety, are included in conjunction with its primary review responsibility for SRP Section 16.0. 2. Quality Assurance Branch (QAB)The Quality Assurance and Maintenance Branch (HQMB) will coordinate the review of geotechnical engineering aspects 14 of the quality
