physical modeling of intake flow fields are appropriate for the specific situation being modeled, have been verified or shown to be conservative, and are documented and referenced. The reviewer should consider the procedures of Regulatory Guides 4.4, Reporting Procedure for Mathematical Models Selected for Predict Heated Effluent Dispersion in Natural Water Bodies (NRC 1974), and 1.125, Rev. 1, Physical Models for Design and Operation of Hydraulic Structures and Systems for Nuclear Power Plants (NRC 1978), in making this evaluation. For analyses involving less detailed procedures than mathematical or physical models, the reviewer should ensure that the procedures used were appropriate for the specific situation and were adequately conservative. For specific physical impacts identified by the “Review Procedures” section, the reviewer should evaluate each impact with regard to water standards and guides or good operating procedures for intake systems. Unless potentially severe impacts have been identified, no further evaluation is required. IV. EVALUATION FINDINGS Input to the EIS should contain the following: (1) a physical description of the induced hydrodynamic flow field resulting from operation of the intake system, (2) a description and assessment of physical impacts resulting from intake system operation, (3) the basis for the staff’s review and analysis, and (4) staff evaluations and conclusions. The extent of the hydrodynamic description input to the EIS should be governed by the potential for impacts on aquatic biota ( ESRP 5.3.1.2). The extent of the physical impacts to be included should be determined by the results of the “Review Procedures” section in identifying potentially significant changes. The following information should be included in the EIS: ` hydrodynamic description of the intake induced flow fields, including effects of ambient flow patterns. Tables or figures may be used.
