4 - March 2007 applicant are based on sound geologic principles and all available geologic and geophysical data. When special investigations are conducted to determine structural relationships between faults that pass within 8 km (5 mi) of the site and regional faults, the reviewer assesses resolution accuracy of the investigative technique used by the applicant. 6. Characterization of Capable Tectonic Sources. The reviewer evaluates information related to characterization of capable tectonic sources presented in the application to determine whether sufficiently detailed investigations have been conducted by the applicant to define specific characteristics of all potential capable tectonic sources, any part of which is located within 8 km (5 mi) of the site (i.e., within the site area). Characteristics of a structure that must be defined include fault orientation; relationship of the fault (or fold) to regional structures; type, amount, and chronologic history of displacements (Including slip rates and recurrence intervals) along the fault; and extent of the deformed zone as established by mapping the extent of Quaternary deformation both along and across the deformed zone to determine length and width of the zone. The reviewer assesses adequacy of the applicant’s field investigations, including whether a large enough area was analyzed in sufficient detail to demonstrate that there is little likelihood of near-surface deformation within the site area associated with capable but undetected tectonic sources (e.g., blind faults). 7. Designation of Zones of Quaternarv Deformation in the Site Region. The reviewer examines published literature to determine acceptability of the applicant's investigative results related to designation of zones of Quaternary deformation in the site region. The reviewer also evaluates investigative techniques employed by the applicant for defining the zones to ascertain whether they are consistent with state-of-the-art practices, and staff
