-published literature. As a result of our recent review 'of the geologic and seismologic information, we have determined that our earlier conclusion regarding the safety of the plant from a geological and seismological standpoint remains valid. These conclusions can be summarized as follows: (1) Geologic and seismologic investigations and information provided by the applicant and required by Appendix A to 10 CFR Part 100 provide an adequate basis to establish that no capable faults exist in the plant site area which would cause earthquakes to be centered there. (2) No evidence has been found to indicate that a potential exists for surface faulting at the plant. (3) The acceleration level 0.25g proposed for the safe shutdown earth- quake is the appropriate acceleration level used to anchor a Regulatory Guide 1.60 spectra for the seismic design of the plant in conformance with Appendix A to 10 CFR Part 100. (4) The potential for detrimental subsidence (resulting from the near-site extraction of groundwater) affecting the proposed nuclear plant is considered nonexistent. 2.5.1-6 Rev. 2 - July 1981 The new information reviewed for the proposed nuclear power plant is discussed in Sections 2.5.1, 2.5.2, and 2.5.3 below. The staff concluded that the site is acceptable from a geologic and seismologic standpoint and meets the requirements of (1) 10 CFR Part 50, Appendix A (General Design Criterion 2), (2) 10 CFR Part 100, and (3) 10 CFR Part 100, Appendix A. This conclusion is based on the following: 1. The applicant has met the requirements of: a. 10 CFR Part 50, Appendix A (General Design Criterion 2) with respect to protection against natural phenomena such as earthquakes, faulting, and collapse. b. 10 CFR Part 100 (Reactor Site Criteria) with respect to the identification of physical characteristics such as geology and seismology used in determining the suitability of the site. c. 10 CFR Part 100, Appendix A (Seismic and Geologic Siting Criteria for Nuclear Power Plants)
