The first phase is the acceptance review, a brief review of the SAR'or ESR to evaluate its completeness and to identify obvious'safety issues that could result in delays at subsequent stages of the review. The judgments on acceptance or rejection of the SAR or ESR for review are governed by two criteria: (1) adherence to the Standard Format (Ref. 6) in identifying and describing the geological, seismological, and geophysical features and the conditions resulting from human activities that affect safety of the site, and (2) provision of adequate information and documentation as described in Regulatory Guide 1.165 (Ref. 3) to allow for an independent staff review of the conclusions made therein. After an SAR or ESR is docketed, the staff conducts a thorough review of the material. In this second phase of the review an effort is made to identify all safety issues. The reviewer carefully examines the SAR or ESR to see that all interpretations are founded on sound geological and seismological practice and do not exceed the limits of validity of the applicant's data or of other data, such as that published in the scientific literature. The SAR or ESR is also reviewed for any significant new information derived by the site-specific geological, seismological, and geophysical investigations that had not been applied to the tectonic-and ground motion models used in the PSHA. Appendix E of Regulatory Guide 1.165 (Ref. 3) discusses an acceptable method to address significant new information in the PSHA. At the beginning of this phase of the review, the staff usually seeks assistance from the USGS and decides to what extent consultants should be involved. The necessary information is then made available to the USGS advisors and consultants. Advisors from the USGS and consultants are asked to perform such varied
