A. The criteria and recommendations in this standard shall apply to site characterization for the purpose of
mitigating Natural Phenomena Hazards in all DOE facilities covered by DOE O 420.1. Criteria for site
characterization not related to NPH are generally not included in this document unless they are deemed
necessary for clarification. General and detailed site characterization requirements are provided in the
areas of meteorology, hydrology, geology, seismology and geotechnical studies.
