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

The California Air Resources Board (CARB) requested approval, under section 112(l) of the Clean Air Act (CAA), to implement and enforce California's ``Airborne Toxic Control Measure for Emissions of Perchloroethylene from Dry Cleaning Operations'' (dry cleaning ATCM) in place of the ``National Perchloroethylene Air Emission Standards for Dry Cleaning Facilities'' (dry cleaning NESHAP) for area sources. In addition, to streamline the approval process for future CAA section 112(l) applications, CARB also requested approval of its demonstration that California has adequate authorities and resources to implement and enforce all CAA section 112 programs and rules, with the exception of the accidental release prevention program to be promulgated pursuant to CAA section 112(r). The Environmental Protection Agency (EPA) has reviewed CARB's requests for approval and has found that these requests satisfy all of the requirements necessary to qualify for approval, with the exception of CARB's supplemental request for the authority to determine equivalent emission control technology for dry cleaning facilities. Thus, EPA is hereby granting California the authority to implement and enforce its dry cleaning ATCM in place of the dry cleaning NESHAP, except for those provisions of the dry cleaning NESHAP that apply to major sources; disapproving CARB's supplemental request for approval of the authority to determine equivalent emission control technology for dry cleaning facilities; and approving CARB's demonstration that California has adequate authorities and resources to implement and enforce all CAA section 112 programs and rules, with the exception of the accidental release prevention program to be promulgated pursuant to CAA section 112(r).
