REVIEW RESPONSIBILITIES Primary—Appendix B Secondary—Appendix B I. AREAS OF REVIEW This environmental standard review plan (ESRP) directs the staff’s description of the surface-water bodies and groundwater aquifers that could affect the plant-water supply and effluent disposal or that could be affected by plant construction or operation of the proposed project, including transmission corridors and offsite facilities. The scope of the review directed by this plan includes consideration of site-specific and regional data on the physical and hydrological characteristics of ground and surface water in sufficient detail to provide the basic data for other reviews addressing the evaluation impacts on water bodies, aquifers, aquatic ecosystems, and social and economic structures of the area. Review Interfaces The reviewer for this ESRP should obtain input from and provide input to the reviewers for the following ESRPs, as indicated: ` ESRP 2.3.2. Obtain descriptions of the region’s water uses (e.g., the location and nature of water users and water-use areas) for the area surrounding the proposed plant site (for the purpose of determining the level of detail required for the description of the hydrology). ` ESRPs 2.3.2, 2.3.3, 2.4.2, 3.4.2, 4.1.1 through 4.1.3, 4.2.1, 4.2.2, 4.3.1, 4.3.2, 5.2.1, 5.2.2, 5.3.1.1, 5.3.1.2, 5.3.2.1, 5.3.2.2, 5.4.1, 5.5.1, 5.5.2, 6.1, 6.3, 6.6, and 9.4.1. Provide descriptive information in ESRP 2.3.1 in sufficient detail to support the descriptions and assessments given in these ESRPs. (a) Features necessary to describe the hydrosphere but that do not provide a basis for assessing impacts need not be described in great detail. (b) “Floodplain” is defined as the lowland and relatively flat areas adjoining inland and coastal waters, including floodplain areas of offshore islands. This includes, at a minimum, that area subject to a 1% or greater chance of flooding in any given year. The base floodplain shall be used to designate the
