Environmental Protection Agency
The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by Connecticut (CT) to address certain Federal requirements for the 2008 and 2015 8-hour ozone National Ambient Air Quality Standard (NAAQS) under the Clean Air Act (CAA). Specifically, the EPA is proposing to approve a source-specific SIP revision for Algonquin Gas Transmission, LLC's compressor station facility, located in Cromwell, CT, to address reasonably available control technology (RACT) determinations for major stationary sources of volatile organic compounds (VOC). These RACT determinations are required because the source is located in the New York-Northern New Jersey-Long Island, NY-NJ-CT 2008 ozone Severe nonattainment area and 2015 ozone serious nonattainment area. The State of Connecticut is also located in the Ozone Transport Region (OTR). Section 172 of the CAA outlines the general nonattainment plan provisions and CAA section 182 requires additional plan requirements for ozone nonattainment areas based on classification status. Additionally, if a state is in the OTR, it is subject to requirements under CAA section 184, which include implementing RACT requirements statewide. The EPA is also proposing to approve a negative declaration for existing rubber tire manufacturing sources statewide. The EPA is proposing to approve the State's submission as a SIP revision pursuant to sections 110, 172, 182, 184 and part D of the CAA and EPA's regulations.
