Air Plan Approval; CT; Reasonably Available Control Technology for the 2008 8-Hour Ozone National Ambient Air Quality Standards

EPA is proposing approval of State Implementation Plan (SIP) revisions submitted by the State of Connecticut for purposes of implementing the 2008 ozone National Ambient Air Quality Standards. The SIP revisions consist of a demonstration that Connecticut meets the requirements of reasonably available control technology for the two precursors for ground-level ozone, oxides of nitrogen (NOX) and volatile organic compounds (VOCs), set forth by the Clean Air Act with respect to the 2008 ozone standards. Additionally, we are proposing approval of three related regulations that limit air emissions of these pollutants from sources within the State. This action is being taken in accordance with sections 172, 182, and 184 of the Clean Air Act.
