dels or improved existing models when selecting a mathematical model. (7) Assess physical changes resulting from the discharge system operation, including shoreline erosion, bottom scouring, increased turbidity and siltation. ` If no severe impacts can be predicted, no further analysis is necessary. NUREG-1555 5.3.2.1-8 October 1999 ` If potentially severe impacts are identified, consider using mathematical modeling or physical modeling to quantify them. (8) Determine compliance with applicable regulations. ` Where required, consult with appropriate Federal, State, regional, local, and affected Native American tribal agencies. ` Become familiar with the provisions of the Second Memorandum of Understanding between NRC and EPA. IV. EVALUATION FINDINGS Input to the EIS should include (1) a description of the thermally affected area, (2) the public disclosure of physical impacts resulting from the discharge system, (3) the basis for the staff analysis, and (4) staff evaluations and conclusions. The following information should be included in the EIS: ` a hydrothermal description of the affected area ` tables or figures depicting isotherms, areas within the isotherms, streamlines, streaklines, or velocity vectors as a function of temporal variations ` descriptions of thermal blocks, recirculation, discharge plume attachment to shorelines, thermal buildup, violation of standards, and potential impacts, such as increased turbidity, scouring, erosion, or sedimentation. The reviewer should verify that sufficient information has been provided in accordance with the relevant requirements and that the evaluation supports the following type of statement to be included in the EIS: Based on the applicant’s description of the methodologies used to conduct a hydrothermal analysis of the discharge system of the proposed plant’s cooling system, the staff concludes that characterization of the physical effects of the hydrothermal discharges is valid and adequate to evaluate the
