of any potential changes to numbers of nuisance, invasive, and introduced species, including fish, aquatic vegetation and benthic invertebrates (e.g., Corbicula spp. or Mytilus spp.) onsite or in the vicinity of the proposed plant as a result of thermal discharges. • Discussion of effects on important aquatic species resulting from chemical alterations (e.g., changes in salinity, dissolved oxygen, and biocides) to the receiving waterbody. Consider effects from both cooling-tower drift and cooling-system discharges. • Discussion of effects on important aquatic species resulting from physical alterations (e.g., maintenance dredging to the receiving waterbody) including its substrate and aquatic vegetation. • Description of any transmission-line and pipeline corridor maintenance practices anticipated to adversely affect aquatic biota. • Summary of any relevant correspondence or discussions with FWS, National Marine Fisheries Service or State, local, or Tribal natural resource agencies on the endangered, threatened or other special status species and habitats including federally designated critical habitat. Briefly summarize and provide copies of key correspondence (including requests and responses by letters, e-mail, or phone call summaries). 5.4 Socioeconomics The ER should describe the socioeconomic impacts from operations on the economic region identified in Chapter 2 of this RG. The economic region is defined by the characteristics within the demographic region surrounding the proposed site. However, the analysis should consider the entire 50- mi radius of the demographic region surrounding the site when appropriate. The scope of the review is guided by the magnitude and nature of the expected impacts associated with operations and by the site- specific community characteristics. 5.4.1 Physical Impacts This section should address the physical impacts to the community, including people, buildings, roads, and the aesthetic quality of the local viewsheds
