Approval of Section 112(l) Authority for Hazardous Air Pollutants; Perchloroethylene Air Emission Standards for Dry Cleaning Facilities; State of Vermont

The Environmental Protection Agency (EPA) is taking direct final action to grant the Vermont Department of Environmental Conservation (VT DEC) the authority to implement and enforce, with respect to area sources only, the Vermont Perchloroethylene Dry Cleaning Rule in place of the National Emissions Standards for Hazardous Air Pollutants for Perchloroethylene Dry Cleaning Facilities (Dry Cleaning NESHAP). Pursuant to the Clean Air Act (CAA), the VT DEC submitted a request for approval to implement and enforce the Perchloroethylene Dry Cleaning Rule of the Vermont Air Pollution Control Regulations as a partial substitution for the National Emissions Standards for Hazardous Air Pollutants for Perchloroethylene Dry Cleaning Facilities (Dry Cleaning NESHAP), as it applies to area sources. EPA has reviewed this request and has determined that the Vermont Perchloroethylene Dry Cleaning Rule satisfies the requirements necessary for partial rule substitution. Thus, EPA is hereby granting VT DEC's request. This action does not affect the authority of any party to implement and enforce the Dry Cleaning NESHAP with respect to major source dry cleaners. This approval makes the Vermont Perchloroethylene Dry Cleaning Rule federally enforceable in Vermont.
