## Abstract

EPA is taking direct final action to approve revisions to the Maryland State Implementation Plan (SIP). The revisions consist of amendments to Maryland's air pollution control regulations governing specific processes that emit volatile organic compounds (VOC). These requirements initially included organic chemicals and are being expanded to include inorganic chemicals and polytetrafluoroethylene (PTFE) products. The revisions also include establishment of a VOC content limit for PTFE coating installations and clarification of applicability thresholds. EPA is fully approving these revisions in accordance with the requirements of the Clean Air Act.
