The Environmental Protection Agency (EPA) is approving State Implementation Plan (SIP) revisions submitted by the State of Connecticut. These SIP revisions consist of a demonstration that Connecticut meets the requirements to implement reasonably available control technology (RACT) for the two precursors of ground-level ozone, oxides of nitrogen (NO<INF>X</INF>) and volatile organic compounds (VOCs), set forth by the Clean Air Act (CAA) with respect to the 2008 ozone standard. Additionally, we are approving three related regulations that limit air emissions of NO<INF>X</INF> from sources within the State. This action is being taken in accordance with the Clean Air Act.
