ed action that are available for reducing the adverse impacts. If an environmental assessment of aquatic impacts is available from the permitting authority, the NRC will consider the assessment in its determination of the magnitude of the environmental impacts in striking an overall benefit-cost balance. If no such assessment of aquatic impacts is available from the permitting authority, the NRC (possibly in conjunction with the permitting authority and other agencies having relevant expertise) will determine the impact. ` Because water quality and water supply are interdependent, changes in water quality must be considered simultaneously with changes in water supply. In Jefferson County PUD #1 vs. Department of Ecology (U.S. Supreme Court Case), the U.S. Supreme Court granted the States additional authority to limit hydrological alterations beyond the State’s role in regulating water rights. NUREG-1555 5.3.2.1-6 October 1999 ` Regulatory Guide 4.2, Rev. 2, Preparation of Environmental Reports for Nuclear Power Stations (NRC 1976), contains guidance on the format and content of ERs including hydrology, water-use, and water-quality issues. Technical Rationale The technical rationale for evaluating the applicant’s thermal description and physical impacts is discussed in the following paragraph: A detailed and thorough description of the thermal and physical impacts of the cooling system’s discharge is essential for the evaluation of potential impacts on the environment that may result from plant, construction or operation. III. REVIEW PROCEDURES The reviewer’s analysis of the thermal discharges should be linked to the environmental descriptions provided by ESRPs 2.3, 2.4.2, 2.7, 3.3, and 3.4 to ensure that the physical environmental factors most likely to be impacted by the proposed plant operation are described in sufficient detail to permit assessment of the predicted impacts. The reviewer should take the following steps: (1) Coordinate with the reviewer for
