Title: Prevention of Significant Deterioration and Nonattainment New Source Review: Emission Increases for Electric Generating Units
Abstract: This rulemaking would revise the emissions test for existing electric generating units (EGUs) that are subject to the regulations governing the Prevention of Significant Deterioration (PSD) and nonattainment major New Source Review (NSR) programs mandated by parts C and D of title I of the Clean Air Act (CAA). The existing emissions test compares actual emissions to either potential emissions or projected actual emissions. Under this rulemaking's revised NSR emissions test (a maximum hourly test like that used in the NSPS program), we would compare the EGU's maximum hourly emissions (considering controls) before the change for the past 5 years to the maximum hourly emissions after the change. The maximum hourly emissions test will be based either on maximum achieved or maximum achievable hourly emissions, measured on an input or an output basis. One proposed option provides that the maximum hourly emissions increase test would be followed by the annual emissions increase test in the current rules.
