users must be consistent with regional hydrologic inventories reported by applicable State and Federal agencies. The description of the hydrologic characteristics of streams, lakes, and shore regions must correspond to those of the United States Geological Survey (USGS), National Oceanic and Atmospheric Administration (NOAA), Soil Conservation Service (SCS), Corps of Engineers, or appropriate State and river basin agencies. Descriptions of all existing or proposed reservoirs and dams (both upstream and downstream) that could influence conditions at the site must be provided. Descriptions may be obtained from reports of the USGS, United States Bureau of Reclamation (USBR), Corps of Engineers, and others. Generally, reservoir descriptions of a quality similar to those contained in pertinent data sheets of a standard Corps of Engineers Hydrology Design Memorandum are adequate. Tabulations of drainage areas, types of structures, appurtenances, ownership, seismic and spillway design criteria, elevation-storage relationships, and short- and long-term storage allocations must be provided. 2. Appendix A, "Hydrologic Engineering Site Visits," to this SRP section details the purposes and procedures of the site visit. The site visit serves to acquaint the reviewer with the site and to provide an independent confirmation of the hydrologic characteristics of the site and adjacent environs. 2.4.1-3 DRAFT Rev. 3 - April 1996 Technical Rationale5 The technical rationale for application of the above acceptance criteria to the review of a hydrologic description of a nuclear power plant site is discussed in the following paragraphs:6 1. Compliance with GDC 2 requires that nuclear power plant structures, systems, and components important to safety be designed to withstand the effects of natural phenomena such as earthquake, tornado, hurricane, flood, tsunami, and seiche without loss of capability to perform their safety functions. The GDC further specifies that the design bases for
