t and content of ERs, including hydrology, water-use, and water-quality issues. Technical Rationale The technical rationale for evaluating the applicant’s potential water-use impacts is discussed in the following paragraphs: A detailed and thorough description of the water use during construction activities is essential for the evaluation of potential impacts to the environment that may result from plant construction or opera- tion. Water quality and water supply are linked. The authority to regulate water quality can be extended to regulate water supply if the domestic or environmental water needs are impacted by reduced water quality. Where an assessment of the environmental impacts resulting from construction activities is available from a separate permitting authority (such as Corps, State, EPA, or NPDES permitting agency), NRC will consider the assessment in its determination of the magnitude of environmental impacts for striking an overall benefit-cost balance. Documentation of adequate consultation with the appropriate permitting authorities is required. III. REVIEW PROCEDURES The reviewer should take the following steps: (1) Evaluate water quantity and availability by identifying water users potentially impacted by alterations in water quantity and availability: (a) Describe any impacts of reduced water quantity and availability. NUREG-1555 4.2.2-6 October 1999 (b) Describe the possibility for inequalities between proposed construction water use and existing and known future water rights and allocations and the probable nature and extent of these inequalities. (2) Evaluate the construction activities and the hydrologic alterations identified in ESRP 4.2.1 with respect to their potential impacts to water users or water-use areas: (a) Compare the effects of these alterations (e.g., increased temperature, salinity, erosion, sedimentation) with pre-construction conditions to assess the magnitude of the impact. (b) Evaluate the impacts for individual water
