pport, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. [Riparian areas are] vegetated ecosystems along a water body through which energy, materials, and water pass. Riparian areas characteristically have a high water table and are subject to periodic flooding and influence from the adjacent water body. These systems encompass wetlands, uplands, or some combination of these two land forms; they do not in all cases have all of the characteristics necessary for them to be classified as wetlands. The NRC generally includes wetland and riparian habitats with terrestrial ecology. The following information on ecological resources should be included in this section of the ER: DG-4015, Page 17 Region The ER should describe the ecoregion, ecosystems, and habitats surrounding the site; the geomorphic, or physiographic, province; characteristic vegetation and animal species, including climax vegetation and typical succession in the area of the site; the ecological province of the ocean if the plant is located near an ocean or estuary; and the watershed and names and locations of source and receiving water bodies for the plant’s cooling system. Site and Vicinity The ER should describe the local environment of the site, including soil types; water and sediment quality; vegetation and animal communities; physiographic habitats such as upland forest, swamps, marshes, wetlands, rivers, streams, and the like; and significant water bodies that intersect or parallel transmission lines. The ER should also include topographic maps and descriptions, as appropriate. Potentially Affected Water Bodies The ER should describe the location of the site, in river miles, if appropriate, with respect to the principal nearby water bodies that it affects. The ER should also describe the source and receiving water bodies in terms of their
