ients, velocities, water levels, and effects of potential future use on these parameters, including any possibility for reversing the direction of groundwater flow using data provided by the applicant and supplemented by data from USGS and other State or Federal agencies. The staff should identify any potential groundwater recharge area within the influence of the plant and effects of 2.4.12-8 Revision 3 - March 2007 construction, including dewatering using hydrogeologic maps and descriptions available from State and Federal agencies. The influence of existing and potential future wells with respect to groundwater beneath the site should be discussed. Bases and sources of data should be described and referenced. Changes resulting from the alteration of hydraulic properties associated with the subsurface portions of the plant and the fill used during construction should also be discussed. Any assumptions and approximations regarding the hydrogeologic properties, aquifer parameters, or boundary conditions need to be documented and described appropriately with justifications. The need for and extent of procedures and measures to protect present and projected groundwater users, including monitoring programs, should be reviewed based upon site-specific groundwater features since these items are site-specific and will vary with each application. 2. Effects on Plant Foundations and Other Safety-Related Structures, Systems, and Components: The design bases (and development thereof) for groundwater-induced loadings on subsurface portions of SSC important to safety are reviewed. Independent calculations should be performed to determine the adequacy of the design criteria and the capability to reflect any potential future changes which can be induced by variations in precipitation, construction of future wells and reservoirs, accidents, pipe failures, or other natural events. 3. Reliability of Groundwater Resources and Systems Used for Safety-Related Purposes: If wells are
