EPA is approving a State Implementation Plan (SIP) revision submitted by the State of Connecticut. The revision consists of approving revisions to subsections 22a-174-20(s), 22a-174-20(v), and 22a-174-20(ee) of Connecticut's regulations, which define reasonably available control technology (RACT) for specific categories of industrial sources which emit volatile organic compounds (VOC), as meeting the requirements of the CAA. This action also involves the conditional approval of a new section 22a-174-32 which defines RACT for sources of VOC which do not fall into any of the other industry- specific categories of Connecticut's VOC control regulations. This action is being taken in accordance with the Clean Air Act.
