The Pennsylvania Environmental Quality Board (EQB) will soon publish amendments to the Department of Environmental Protection’s (PADEP) regulations in 25 Pa. Code Chapters 121 and 129 for all major stationary sources of nitrogen oxides (NOx) or volatile organic compound (VOC) emissions, commonly known as the RACT III rule. The rule would require major sources of either or both of these air pollutants in existence on or before August 3, 2018 to meet “reasonably available control technology” (RACT) emission limits and requirements by January 1, 2023.
These regulations are being promulgated to address Federal Clean Air Act (CAA) RACT requirements to meet the 2015 ozone National Ambient Air Quality Standards (NAAQS) in the Commonwealth. The CAA requires a reevaluation of RACT when new ozone NAAQS are promulgated. RACT is required in nonattainment areas, including the Ozone Transport Region which includes Pennsylvania. The RACT III rulemaking establishes presumptive RACT requirements and emission limits for specific source categories of affected facilities. The RACT III rulemaking also imposes additional requirements for all major sources of NOx and/or VOCs, not just those subject to the presumptive RACT requirements and limitations.
RACT III applies to all major sources of VOCs and NOx. Because the Commonwealth is in the Northeast Ozone Transport Region, the major source threshold is 50 tons per year of VOCs and 100 tons per year of NOx. PADEP estimates that 425 Title V facility owners and operators will be subject to the final rule. Affected source categories include combustion units; municipal solid waste landfills; municipal waste combustors; process heaters; turbines; stationary internal combustion engines; Portland cement kilns; glass melting furnaces; lime kilns; direct-fired heaters, furnaces or ovens; …
