ge (e.g., latest U.S. Global Change Research Program Report), but applicable regional and local studies conducted by other entities may be included. 2.7.2 Air Quality The applicant should describe the air quality at the site and surrounding region and provide sufficient detail to evaluate impacts from building and operating the plant. The following information should be provided: • A description of the site and regional air quality, including the Air Quality Control Region as listed in 40 CFR Part 81, “Designation of Areas for Air Quality Planning Purposes” (Ref. 43). • Identification of any nonattainment or maintenance areas with respect to criteria air pollutants identified in 40 CFR Part 50, “National Primary and Secondary Ambient Air Quality Standards” (Ref. 44). • Location of nearest Mandatory Federal Class 1 Areas (40 CFR Part 81), where air quality and visibility are protected under the Regional Haze Program. DG-4026, Page 49 • Discussion of greenhouse gases (GHGs) and estimates of yearly emissions (expressed in units of CO2 equivalents7) at a global, national, and state level and, if available, provide State or Public Utility Commission GHG emission reduction goals. This discussion should be based on values provided by Federal agencies with a mandate to estimate GHG emissions and is needed to provide context for GHG emissions from the proposed project (See Attachment 1 to COL/ESP- ISG-26, “Attachment 1: Staff Guidance for Greenhouse Gas and Climate Change Impacts for New Reactor Environmental Impact Statements” (Ref. 45)). 2.7.3 Atmospheric Dispersion The applicant should provide short-term dispersion estimates for use in evaluation of dose from design-basis accidents and long-term dispersion and deposition estimates for evaluation of radiological impacts from normal operations. The applicant should provide meteorological data from at least two consecutive annual cycles (and preferably three or more entire years), including the most
