Content:
tonic setting of plants in regions of complex geology, evaluating potential for surface deformation due to faulting, verifying an applicant's geochronology for fault displacement, and providing advice on levels of earthquake ground motion for seismic evaluation of selected sites. A literature search and review of relevant references (e.g., published geological reports, USGS professional papers and open-file reports, university theses, physiographic and geologic maps, and aeromagnetic and gravity maps) is conducted by NRC staff and its advisors and consultants to acquire additional pertinent information on regional and local geology and seismology. However, as publication of data and results commonly lags behind completion of research projects and construction investigations, a reviewer should not rely entirely on information submitted by the applicant or that in published literature. The reviewer should identify any pertinent studies underway in the site vicinity, site area, or at the site location and obtain information on preliminary results of these studies. Special provisions may be required to examine any pertinent data that are of a proprietary nature. As part of the Phase 2 review, staff will conduct geologic reconnaissance of the site vicinity, site area, and site location as necessary to examine soil and rock samples from core borings and test pits and geologic features in trenches and excavations for plant facilities, if these information sources exist. Since geologic features (e.g., deformation due to faulting) which have the potential to adversely impact site safety may be 2.5.3-12 Revision 4 - March 2007 discovered in plant excavations or during other field investigations, this reconnaissance is deemed necessary in light of requirements and procedures specified in Subpart C of 10 CFR Part 52 which allows for a COL (i.e., a combined CP and OL) as an alternative to the two-step licensing process previously defined in 10 CFR Part 50 which includes a CP
