vided by the applicant as required by 10 CFR 52.79(a)(iii), 10 CFR Part 50, Appendix A, GDC 2 and 10 CFR 100.23 have been combined with the staff's independent review of the data and other information sources. The staff concludes that the applicant has investigated the geological characteristics of the site and its environs in sufficient scope and detail to permit an adequate evaluation of the proposed site, as required by 10 CFR 100.23(c). Staff concludes that the size of the region investigated is appropriate for the geologic setting of the proposed site, and that all geologic factors that might affect the design and operation of the proposed facility have been investigated. Staff concludes that the applicant has acceptably characterized the most severe of the geologic phenomena that have been historically reported for the site and surrounding area, and has provided sufficient margin in this characterization to account for the limited accuracy, quantity, and period of time in which the historical data have been accumulated, as required by 10 CFR 52.79(a)(iii). This characterization is acceptable as a design basis for protection against natural phenomena, as required by 10 CFR Part 50, Appendix A, GDC 2(1). In order to verify that no geologic features or conditions exist beneath the safety-related structures at the site that could affect the design and operation of the facility, the staff proposes a license condition requiring an applicant to: (1) perform detailed geologic mapping of the excavations for safety-related structures; (2) examine and evaluate geologic features discovered in excavations for safety-related structures; and (3) notify the NRC once excavations for safety-related structures are open for inspection by NRC staff. For COL applications that do not reference a previous ESP, staff evaluation findings will include the evaluation findings identified above for ESP reviews. For a COL referencing a previous ESP, 2.5.1-2 Draft Revision 5 – August 2013
