tion 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 relationship to the watershed; size; shoreline; bathymetry; tidal and net flows, including seasonal or occasional variations; substrata; and sediment and water quality. This section should include the location of the main channel, dams, and flood control and describe uses of the water body other than as cooling water. History The ER should provide a short description of the ecological environment before European settlement and the transition of the environment on the site from before plant construction to the present. This description should include major changes or modifications to the land and/or water bodies over the projected life of the plant. Typically, the ER should describe channelization, navigation, pollution, habitat degradation or fragmentation, urbanization, development, and pond or reservoir creation. This description should also include pollution control or other programs designed for environmental improvement. The ER should briefly describe major wildlife living around site in the past and which species remain today. If appropriate, the ER should refer to cultural resources when possible to avoid repeating information. Places and Entities of Special Interest The ER should provide the occurrence, location, and description of communities and habitats of special interest in the vicinity of plant, such as wetlands, natural heritage areas and other areas of public or scientific interest, or other areas that may be particularly sensitive or susceptible either directly or indirectly to the effects of continued plant operations and refurbishment. Aquatic Communities The ER should briefly describe the aquatic communities based on available information (e.g., present and past studies, Federal and State sources). This description should focus on a subset of
