Approval and Promulgation of Air Quality Implementation Plans; Maryland; Control of Volatile Organic Compound Emissions From Industrial Solvent Cleaning Operations

EPA is taking direct final action to approve a State Implementation Plan (SIP) revision submitted by the Maryland Department of the Environment (MDE). This SIP revision consists of an addition to Maryland's Volatile Organic Compounds from Specific Processes Regulation. MDE has adopted standards for industrial solvent cleaning operations that satisfy the reasonably available control technology (RACT) requirements for sources of volatile organic compounds (VOCs) covered by control techniques guidelines (CTG). This amendment reduces VOC emissions from industrial solvent cleaning operations which will help Maryland attain and maintain the National Ambient Air Quality Standards (NAAQS) for ozone. This action is being taken under the Clean Air Act (CAA).
