Air Plan Approval; Massachusetts; Reasonably Available Control Technology for the 2008 and 2015 Ozone Standards
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the Commonwealth of Massachusetts. The SIP revision consists of a demonstration that Massachusetts meets the requirements of reasonably available control technology (RACT) for the two precursors for ground-level ozone, oxides of nitrogen (NO<INF>X</INF>) and volatile organic compounds (VOCs), set forth by the Clean Air Act (CAA or Act) with respect to the 2008 and 2015 ozone National Ambient Air Quality Standards (NAAQSs or standards). Additionally, we are approving specific regulations that implement the RACT requirements by limiting air emissions of NO<INF>X</INF> and VOC pollutants from sources within the Commonwealth. This action is being taken in accordance with the Clean Air Act.
