ing towers (these are redundant towers and serve as the ultimate heat sink), and various groundwater wells. The staff concludes that the requirements of General Design Criterion 2 and 10 CFR Part 100, with respect to general hydrologic descriptions, have been met. This conclusion is based upon the following: The applicant has provided sufficient information pertaining to the general hydrologic characteristics of the site including descriptions of water bodies, water control structures, and water users. V. IMPLEMENTATION The following is intended to provide guidance to applicants and licensees regard- ing the NRC staff's plans for using this SRP section. Except in those cases in which the applicant proposes an acceptable alternative method for complying with specified portions of the Commission's regulations, the method described herein will be used by the staff in its evaluation of con- formance with Commission regulations. Implementation schedules for conformance to parts of the method discussed herein are contained in the referenced regulatory guides and NUREGs. VI. REFERENCES Because of the geographic diversity of plant sites and the large number of hydrologic references, no specific tabulation is given here. In general, maps and charts by the USGS, NOAM, Army Map Service (AMS), and Federal Aviation Administration (FAA); water-supply papers of the USGS; River Basin Reports of the Corps of Engineers; and other publications of state, federal and other 2.4.1-3 Rev. 2 - July 1981 regulatory bodies, describing hydrologic characteristics and water utilization in the plant vicinity and region, are referred to on an "as-available" basis. Other SRP sections in the hydrology area (2.4.2 through 2.4.14) contain references that are to be used in evaluating the hydrologic description of the site. 1. 10 CFR Part 50, Appendix A, General Design Criterion 2, "Design Bases for Protection Against Natural Phenomena." 2. 10 CFR Part 100, "Reactor Site Criteria." 3.
