Approval and Promulgation of Air Quality Implementation Plan; Maryland; Reasonably Available Control Technology Requirements for Volatile Organic Compounds

EPA is taking final action to fully approve revisions to the Maryland State Implementation Plan (SIP). The revisions pertain to Maryland's major source volatile organic compound (VOC) reasonable available control technology (RACT) regulation. EPA is converting the conditional limited approval status of Maryland's VOC RACT regulations to a full approval because EPA has approved all of the case-by-case RACT determinations submitted by Maryland pursuant to the generic provisions of its VOC RACT regulation as well as all of the RACT requirements for categories of VOC sources submitted by Maryland in accordance with the requirements of the Clean Air Act (CAA).
