ata and evaluated by staff. The reviewer should confirm that sufficient information is presented in the application to enable a comparison 2.5.3-7 Revision 4 - March 2007 between new data derived from investigations in the site vicinity, site area, and site location and those data used in tectonic and ground motion models for PSHA. 1. Geologic, Seismic, and Geophysical Investigations. Requirements of GDC 2 in Appendix A of 10 CFR Part 50, 10 CFR 52.17, and 10 CFR 100.23 are met and guidance in Regulatory Guides 1.165, 1.132, 1.198, 1.208, and 4.7 followed for this area of review if discussions of Quaternary tectonics, structural geology, stratigraphy, geochronologic methods used for age dating, paleoseismology, and geologic history of the site vicinity, site area, and site location are complete, compare well with studies conducted by others in the same area, and are supported by detailed investigations performed by the applicant. Site vicinity, site area, and site location-specific geologic maps and cross-sections constructed at scales adequate to clearly illustrate surficial and bedrock geology, structural geology, topography, and relationship of power plant foundations to these features should be included in the application. For coastal and inland sites near large bodies of water, similar detailed investigations are to be conducted and the application should include information regarding onshore and offshore geology and seismicity. In some cases, it may be possible to identify onshore expression of an offshore tectonic structure (i.e., a fault or fold) of potential concern. As expressed in Regulatory Guide 1.165, Appendix D, and RG 1.208, Appendix C, under this condition it is acceptable for the applicant to investigate expression of the offshore structure in the onshore environment, along with other investigations of the offshore feature when possible, to better evaluate characteristics of the tectonic structure in the site vicinity and site area and at the site
