Approval of the Clean Air Act, Section 112(l), Authority for Hazardous Air Pollutants; Perchloroethylene Air Emission Standards for Dry Cleaning Facilities; State of Washington; Puget Sound Clean Air Agency

Pursuant to section 112(l) of the Clean Air Act (CAA), the State of Washington Department of Ecology (Ecology) submitted a request on behalf of the Puget Sound Clean Air Agency (Puget Sound Clean Air) for approval to implement and enforce Puget Sound Clean Air's Regulation III, section 3.03, Perchloroethylene Dry Cleaners in place of federal National Perchloroethylene Air Emission Standards for Dry Cleaning Facilities ("dry cleaning NESHAP"), 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 Puget Sound Clean Air the authority to implement and enforce its Perchloroethylene Dry Cleaners regulation in place of the federal dry cleaning NESHAP, for area sources under Puget Sound Clean Air's jurisdiction. This approval makes Puget Sound Clean Air's rules federally enforceable and reduces the burden on area sources within Puget Sound Clean Air's jurisdiction such that they will only have one rule with which they must comply. Major sources remain subject to the federal dry cleaning NESHAP, as adopted into Puget Sound Clean Air Regulation III, Section 2.02.
