area, and are supported by detailed investigations performed by the applicant. In the case of coastal and inland . sites near large bodies of water, similar detailed investigations are'to be conducted offshore as well as onshore. Site and regional geologic maps and profiles constructed at scales adequate to illustrate clearly the surficial and bedrock geology, structural geology, topography, and the relationship of the safety-related foundations of the nuclear power plant to these features should be included in the SAR. 2.5.3-2 Rev. 2 - July 1981 Subsection 2.5.3.2. In meeting the requirements of References 1, 2, and 3, this subsection is acceptable if sufficient surface and subsurface information is provided and supported by detailed investigations, either to confirm the absence of faulting or, if faulting is present, to demonstrate its age. If faulting is present in the site vicinity, it must be defined as to fault geometry, amount and sense of movement, recurrence rate, and age of latest movement. In addition to geologic evidence which may indicate faulting, linears interpreted from topographic maps, low- and high-altitude aerial photographs, Landsat, Skylab, and other imagery should be documented and investigated. In order to expedite the review process, an identification list, index, and duplicates of the remote- sensing data used in the linear study should be provided to the staff. Evidence for absence of faulting is obtained by conducting site surface and subsurface investigations in such detail and areal extent to ensure that undetected offsets are not likely to exist. These investigations will vary in detail according to the geological complexity of the specific site. Subsection 2.5.3.3. In meeting the requirements of References 1, 2, and 3, this subsection is acceptable if all historically reported earthquakes within 5 miles of the site or near faults which trend within 5 miles of the site, as discussed in SRP Section 2.5.2, are evaluated with respect to
