uantity and/or availability of water resulting from hydrologic alterations. The applicant should evaluate the water-use impacts by quantifying the anticipated reduction in water-supply reliability for each water use and provide a description of the analyses performed to determine the impacts during operations. 5.2.3 Water-Quality Impacts The applicant should identify those water uses and water users discussed in Chapter 2 of this RG that are potentially affected by the changes in water quality resulting from hydrologic alterations during operations. The applicant should evaluate the impacts by quantifying the anticipated reduction in each use resulting from the changes in water quality and provide a description of the analyses performed to determine the impacts. 5.2.4 Water Monitoring The overall plan for protection of waterbodies that may be affected by station operations should be discussed. A description of the proposed measures to ensure compliance with applicable water-quality and water-use standards and regulations should also be provided. When compliance involves monitoring, the operational monitoring program should be described in sufficient detail to justify the ability of the monitoring to provide timely and accurate information so that appropriate actions can be taken to limit the impacts of station operations. 5.3 Ecological Resources This section addresses the information related to terrestrial, wetland and aquatic ecological impacts from operations at the proposed site. The applicant should provide adequate details in the ER to fully determine the impacts to terrestrial and aquatic species and habitats resulting from nuclear power plant operations. 5.3.1 Terrestrial and Wetland Impacts Operation of a nuclear power plant, once built, does not normally involve further physical loss of terrestrial habitats or wetlands but can still affect habitat quality and wildlife.
