requirements in 10 CFR 100.23, acceptance of this subsection is based on the development of the relationship between the history of earthquake activity and seismic sources of a region. For CEUS sites, when the GMRS is determined using LLNL or EPRI PSHA data bases, and Regulatory Guide 1.165 or Regulatory Guide 1.208, this subsection is acceptable when adequate information is provided to demonstrate (1) that a thorough investigation has been conducted to assess the seismicity and identify seismic sources that could be significant in estimating the seismic hazards of the region if they exist, and (2) that existing sources (in the PSHA) are consistent with the results of site and regional investigations or the sources have been updated in accordance with the Appendix E of Regulatory Guide 1.165 or the Appendix C of Regulatory Guide 1.208. For sites where LLNL or EPRI data bases are not used and it is necessary to identify and characterize seismic sources in meeting the requirements of 10 CFR 100.23, adequate information must be provided in this subsection to demonstrate that all seismic sources that are significant in determining the earthquake potential of the region have been identified, or that an adequate investigation has been carried out to provide reasonable assurance that there are no unidentified significant seismic sources. 2.5.2-7 Revision 4 - March 2007 The applicant's presentation is accepted when the earthquakes discussed in Subsection
