tion in the SAR or ESR must be complete and thoroughly documented, and it must be consistent with the requirements of Reference 2 and should conform to the format suggested in Reference 6. Information from varied sources, including the United States Geological Survey (USGS) and other Federal or State agencies' published and open file papers, maps, aerial photographs, geophysical data, and similar data from nongovernmental sources covering the region in which the site is located, are used by the staff in evaluating the completeness and acceptability of the SAR or ESR. The ECGB reviewers must ensure that investigations, as described in Regulatory Guide 1.165 (Ref. 3) and Regulatory Guide 1.132 (Ref. 4), are conducted with the appropriate level of thoroughness within the 4 areas designated in Regulatory Guide 1.165, based on distances from the site: 320 km (200 mi), 40 km (25 mi), 8 km (5 mi), and 1 km (0.6 mi). There must be sufficient information presented in the ESR or SAR on which to base a comparison between the new data derived from the regional and site investigations and that used in the tectonic and ground motion models of the PSHA (Ref. 3). Specific criteria necessary to meet the relevant requirements of General Design Criterion 2, Part 50, and 10 CFR 100.23 are as follows: Subsection 2.5.1.1. "Regional Geologv." In meeting the requirements of References 1 and 2, the subsection will be considered acceptable if a complete and documented discussion is presented of all geological, seismological, and geophysical features, as well as conditions caused by human activities. This subsection should contain a review of the regional tectonics, with emphasis on the Quaternary period, structural geology, seismology, paleoseismology, physiography, geomorphology, stratigraphy, and geologic history within a distance of 320 km (200 mi) from the site (site region), to provide a framework within which the safety significance can be evaluated for the geology, seismology, and
