important to the design and siting of this plant. The staff has reviewed the available information provided and, for the reasons given above, concludes that the identification and consideration of the local 2.4.2-14 Revision 4 - March 2007 intense precipitation and flooding at the site and in the surrounding area are acceptable and meet the requirements of [10 CFR Part 50, Appendix A, General Design Criterion 2, or 10 CFR 52.79, as applicable] and 10 CFR Part 100 [10 CFR Part 100.10(c) or 10 CFR Part 100.20(c), as applicable], with respect to determining the acceptability of the site. The staff finds that the applicant has considered the appropriate site phenomena for establishing the site characteristics for SSCs important to safety. The staff has generally accepted the methodologies used to determine the local intense precipitation, flooding causal mechanisms, and controlling flooding mechanism reflected in these site characteristics, as documented in safety evaluation reports for previous licensing actions. Accordingly, the staff concludes that the use of these methodologies results in site characteristics containing margin sufficient for the limited accuracy, quantity, and period of time in which the data have been accumulated. The staff concludes that the identified design bases meet the requirement(s) of [10 CFR Part 50, Appendix A, General Design Criterion 2 or 10 CFR 52.79, as applicable] and 10 CFR 100.10(c) [or 10 CFR 100.20(c)], with respect to establishing the design basis for SSCs important to safety. 2. Early Site Permit Reviews The following statements should be preceded by a summary of the site characteristics and design parameters to be included in any ESP that might be issued for the proposed site: As set forth above, the applicant has presented and substantiated sufficient information pertaining to the local intense precipitation, flooding causal mechanisms, and the controlling flooding mechanism at the proposed site.
