ntal Reports for Nuclear Power Stations (NRC 1976), contains guidance to the applicant concerning the analysis of potential impacts of operation of the cooling water intake system. The reviewer should ensure that the applicant’s analysis is sufficient to evaluate impacts during station operation. ` Regulatory Guide 4.7, Rev. 2, General Site Suitability for Nuclear Power Stations (NRC 1998) contains guidance concerning the ecological systems and biota at potential sites and requires that their environs be sufficiently well known to allow reasonably certain predictions of impacts and that there are no unacceptable or unnecessary deleterious impacts on populations of important species or on ecological systems from the construction or operation of a nuclear power station. This guide also provides regulatory positions concerning entrainment, impingement, or other forms of entrapment and effects of cooling systems on aquatic species migration routes. ` Compliance with environmental quality standards and requirements of the Clean Water Act is not a substitute for and does not negate the requirement for NRC to weigh the environmental impacts of the proposed action, including any degradation of water quality, and to consider alternatives to the proposed 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. When 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 conduct its own assessment and use it in its determination of the overall benefit-cost balance. ` Memorandum of Understanding Between the Corps of Engineers, U.S. Army, and the NRC for the Regulation of Nuclear Power Plants (40
