dial distance, then the geographic area of interest should include the extended linear corridors such as transmission lines or pipelines. Aquatic Ecology A geographic area of interest could be defined according to salinity regimes, watersheds, substrate, or other environmental characteristics that define suitable habitat ranges and preferences of aquatic resources in the area affected by the project. The geographic area of interest also includes those areas (such as impoundments or facilities affecting water quality) that have or will add to the incremental effects of the project on aquatic habitats. Socioeconomics and Environmental Justice The geographic area of interest should encompass the areas of effect and the distances at which impacts of building and operating over the expected license term may occur. The scope will depend on the extent of project activities, but normally would include the site, the local community, the economic region, and demographic region identified in Chapter 2. Historic and Cultural Resources The geographic area of interest for the cumulative analysis would be the same APE(s) described in Chapters 4 and 5. Air Quality The geographic area of interest for criteria pollutants is the local/regional area and is generally the county where the licensing activity is taking place. Nonradiological Health The geographic area of interest changes based on the type of health effect. For example, acute or chronic EMF exposure is possible at the site and along the transmission corridor, whereas etiological agents are a threat in the vicinity of the thermal discharges. Radiological Health The geographic area of interest is considered to be the area that has the potential to increase radiological exposure at any location within a 50-mi radius of the proposed site. Postulated Accidents The geographic area of interest is considered to be the area that has the potential to increase risks at any location within a 50-mi radius of the proposed site. Fuel
