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

EPA is approving a State Implementation Plan (SIP) revision submitted by the State of Maryland. These revisions pertain to the adoption of various test methods, calculations methods, work practice standards and exemptions which make Maryland Department of the Environment (MDE) regulations more consistent with EPA's Control Techniques Guidelines (CTGs) for seven source categories. These categories are: Paper, film, and foil coatings; industrial cleaning solvents; miscellaneous metal and plastic parts coatings; large appliance coatings; offset lithographic printing and letterpress printing; flat wood paneling coatings; and flexible package printing. EPA is approving these revisions to reduce volatile organic compound (VOC) emissions from these seven categories which will help Maryland attain and maintain the National Ambient Air Quality Standards (NAAQS) for ozone in accordance with the requirements of the Clean Air Act (CAA).
