is presented in other sections of Chapter 2.5, it may be cross-referenced and not repeated in this section. Subsection 2.5.3.1 Geological, Seismological, and Geophysical Investigations. In meeting the requirements of References 1 and 2 and the positions of References 3 and 4, this subsection is considered acceptable if the discussions of the Quaternary tectonics, structural geology, stratigraphy, geochronological methods used, paleoseismology, and geological history of the site are complete, compare well with studies conducted by others in the same area, and are supported by detailed investigations performed by the applicant. For coastal and inland sites near large bodies of water, similar detailed investigations are to be conducted, and the information is to be provided in the SAR or ESR regarding offshore geology and seismology as well as onshore. In some instances it may be possible to identify an onshore projection of the offshore fault or fold of concern, or a tectonic structure that is analogous to it at an onshore location. It is acceptable to the staff, along with other investigations of the specific feature, to investigate the more remote, accessible exposure to learn the nature of the potentially hazardous offshore or buried fault and apply it to the local structure (Refs. 3 and 11). Site and regional 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 have been included in the SAR or ESR. Subsection 2.5.3.2 Geological Evidence, or Absence of Evidence, for Surface Deformation. 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 surface tectonic deformation (i.e., faulting) or, if present, to
