Approval of the Clean Air Act, Section 112(l), Authority for Hazardous Air Pollutants: Perchloroethylene Dry Cleaner Regulation Maine Department of Environmental Protection

Pursuant to section 112(l) of the Clean Air Act ("CAA"), the Maine Department of Environmental Protection ("ME DEP") submitted a request for approval to implement and enforce "Chapter 125: Perchloroethylene Dry Cleaner Regulation" in place of the National Emissions Standard for Hazardous Air Pollutants for Perchloroethylene Dry Cleaning Facilities ("Dry Cleaning NESHAP") as it applies to area sources. EPA has reviewed this request and determined that it satisfies the requirements necessary for approval. Thus, EPA is hereby granting ME DEP the authority to implement and enforce its perchloroethylene dry cleaner regulation in place of the Dry Cleaning NESHAP for area sources. This approval makes the ME DEP rule federally enforceable. Major sources remain subject to the Federal Dry Cleaning NESHAP.
