Approval of Section 112(l) Authority for Hazardous Air Pollutants; District of Columbia; Department of Health

EPA is taking direct final action to approve the District of Columbia (the District) Department of Health's (DoH's) request for delegation of authority to implement and enforce its hazardous air pollutant general provisions and hazardous air pollutant emission standards for perchloroethylene dry cleaning facilities, hard and decorative chromium electroplating and chromium anodizing tanks, halogenated solvent cleaning, and publicly owned treatment works, as well as the test methods, which have been adopted by reference from the Federal requirements set forth in the Code of Federal Regulations (CFR). This approval will automatically delegate future amendments to these regulations once the District incorporates those amendments into its regulations. In addition, EPA is taking direct final action to approve the District's mechanism for receiving delegation of future hazardous air pollutant regulations. This mechanism entails DoH's incorporation by reference of the Federal standard (unchanged), into its hazardous air pollutant regulation, DoH's notification to EPA of such incorporation, and DoH's submission of a delegation request letter to EPA following EPA notification of a new Federal requirement. EPA is not waiving its notification and reporting requirements, therefore, sources will need to send notifications and reports to both DoH and EPA. This action pertains to affected sources, as defined by the Clean Air Act's (CAA or the Act) hazardous air pollutant program. EPA is taking this action in accordance with the Act.
