Air Plan Approval; Maine; Reasonably Available Control Technology for the 2008 Ozone Standard

The Environmental Protection Agency (EPA) is approving State Implementation Plan (SIP) revisions submitted by the State of Maine for purposes of implementing the 2008 Ozone National Ambient Air Quality Standards (NAAQS). The revisions consist of a demonstration that Maine meets the requirements of reasonably available control technology (RACT) for volatile organic compounds (VOCs), set forth by the Clean Air Act (CAA or Act), with respect to the 2008 Ozone standards. Additionally, we are approving a related regulation that limits air emissions of VOCs from certain industrial sources that use organic solvents in cleaning activities, and withdrawing several previously approved source-specific RACT requirements for sources that have ceased operation. This action is being taken under the Clean Air Act.
