on of regional and local groundwater aquifers, sources, and sinks is required. In addition, the type of groundwater use, wells, pump and storage facilities, and the flow requirements of the plant must be described. If groundwater is to be used as an essential source of water for safety-related equipment, the design basis for protection from natural and accident phenomena must compare with Regulatory Guide 1.27 guidelines. Bases and sources of data must be adequately described. 2.4.12-3 DRAFT Rev. 3 - April 1996 To meet the requirements of the hydrologic aspect of 10 CFR Part 100, the following specific criteria are used: For SAR 2.4.12.2: A description of present and projected local and regional groundwater use must be provided. Existing uses, including amounts, water levels, location, drawdown, and source aquifers must be discussed and should be tabulated. Flow directions, gradients, velocities, water levels, and effects of potential future use on these parameters, including any possibility for reversing the direction of groundwater flow, must be indicated. Any potential groundwater recharge area within the influence of the plant and effects of construction, including dewatering, must be identified. The influence of existing and potential future wells with respect to groundwater beneath the site must also be discussed. Bases and sources of data must be described and referenced. For SAR Section 2.4.12.3: The need for and extent of procedures and measures to protect present and projected groundwater users, including monitoring programs, must be discussed. These items are site-specific and will vary with each application. To meet the requirements of 10 CFR Part 50, §§ 50.55 and 50.55a; General Design Criteria 2, 4, and 5; 10 CFR Part 100; and 10 CFR Part 100, Appendix A, the following specific criteria are used: For SAR Section 2.4.12.4: The design bases (and development thereof) for groundwater-induced loadings on subsurface portions of safety-related structures,
