n to be seismically active. 6. Characterization of Capable Tectonic Sources. Requirements of GDC 2 in Appendix A of 10 CFR Part 50, 10 CFR 52.17, and 10 CFR 100.23 are met for this area of review when it has been demonstrated that investigative techniques employed by the applicant are sufficiently sensitive to identify all potential capable tectonic sources, such as faults 2.5.3-9 Revision 4 - March 2007 or structures associated with blind faults, within the site area; and when fault geometry, length, sense of movement, amount of total displacement and displacement per faulting event, age of latest and any previous displacements, recurrence rate, and limits of the fault zone are provided for each capable tectonic source. Investigations must extend to at least 8 km (5 mi) beyond all plant site boundaries to encompass the site area, including for those sites adjacent to large bodies of water such as oceans, rivers, and lakes. 7. Designation of Zones of Quaternarv Deformation in the Site Region. Requirements of GDC 2 in Appendix A of 10 CFR Part 50, 10 CFR 52.17, and 10 CFR 100.23 regarding designation of zones of Quaternary deformation in the site region are met if the zone (or zones) designated by the applicant as requiring detailed faulting investigations is of sufficient length and width to include all Quaternary deformation features potentially significant to the site as described in Regulatory Guides 1.165 and 1.208. 8. Potential for Surface Tectonic Deformation at the Site Location. To meet requirements of GDC 2 in Appendix A of 10 CFR Part 50, 10 CFR 52.17, and 10 CFR 100.23 for this area of review, information must be presented by the applicant in this subsection if field investigations reveal that surface or near-surface tectonic deformation along a known capable tectonic structure (i.e., a known capable tectonic feature related to a fault or blind fault) must be taken into account at the site location. It is important to note that no commercial nuclear power
