Approval of the Clean Air Act, Section 112(l), Authority for Hazardous Air Pollutants: Perchloroethylene Air Emission Standards for Dry Cleaning Facilities: Commonwealth of Massachusetts Department of Environmental Protection

Pursuant to section 112(l) of the Clean Air Act (CAA), the Massachusetts Department of Environmental Protection submitted a request for approval to implement and enforce 310 CMR 70.01-04 Environmental Results Program (ERP) Certification and 310 CMR 7.26(10)- (16) Perchloroethylene Air Emissions Standards for Dry Cleaning Facilities in place of National Emissions Standard for Hazardous Air Pollutants (NESHAP) for Perchloroethylene Dry Cleaning Facilities as it applies to area sources. EPA has reviewed this request and found that it satisfies the requirements necessary to qualify for approval. Thus, EPA is hereby granting the Massachusetts Department of Environmental Protection the authority to implement and enforce its perchloroethylene air emissions regulation in place of the Federal dry cleaning NESHAP for area sources. This approval makes the Massachusetts Department of Environmental Protection rule federally enforceable and reduces the burden on area sources within the state of Massachusetts as that they will only have one rule with which they must comply. Major sources remain subject to the Federal dry cleaning NESHAP.
