The Environmental Protection Agency (EPA) is taking final action to find that the states of New York and Pennsylvania failed to submit State Implementation Plan (SIP) revisions required by the Clean Air Act (CAA) in a timely manner to address reasonably available control technology (RACT) requirements associated with the 2016 Oil and Natural Gas Industry Control Techniques Guidelines (CTG) for reducing volatile organic compounds (VOC). The RACT requirements associated with the CTG apply in certain nonattainment areas for the 2015 ozone National Ambient Air Quality Standards (NAAQS) and in states in the Ozone Transport Region (OTR). Both New York and Pennsylvania are in the OTR. This action triggers certain CAA deadlines for the EPA to impose sanctions if a state does not submit a complete SIP addressing the outstanding requirements and for the EPA to promulgate a Federal Implementation Plan (FIP) if the EPA does not approve the state's SIP revision.
