Content:
– monthly and/or seasonal and annual plume lengths – monthly and/or seasonal and annual additional hours of fogging and icing – monthly and/or seasonal and annual amounts of salt deposition – monthly and/or seasonal and annual increases in humidity and precipitation, including snowfall – potential local weather modification from cloud formation/shadowing – interactions of plume with other pollutant sources 5.7.2 Air-Quality Impacts The applicant should describe air-quality impacts associated with operations. The description should include the following: • Identification of applicable Federal, State, and local air regulations and required air permits for operation. • Sources and types of air pollutant emissions, including mitigating measures, and plans to minimize air emissions. • Estimates of annual air emissions for criteria air pollutants identified in the National Ambient Air Quality Standards. If the proposed site is located in a nonattainment or maintenance area with respect to a criteria pollutant, the emission estimates can be used as a basis for assessing the applicability of a conformity analysis (see 40 CFR Part 93, Subpart B and NRC Memorandum “Revision to Staff Guidance for Conducting General Conformity Determinations” Ref. 56). The applicant should also provide estimates of greenhouse gas (GHG) emissions (expressed in units of CO2 equivalents), including GHG emissions from standby diesel generators and workforce transportation and comparison of these GHG emissions to state and national GHG emissions and, if available, State or Public Utility Commission GHG emission reduction goals (from Chapter 2). The applicant may provide either site-specific estimates or refer to the generic GHG footprint for a 1000- DG-4026, Page 94 MW(e) reactor outlined in COL-ISG-26 (Ref. 45), 12 subsequent interim staff guidance, or other regulatory guidance. 5.7.3 Transmission-Line Impacts The applicant should describe air-quality impacts associated with
