Section 608 of the Federal Clean Air Act requires that all persons who maintain, service, repair, or dispose of appliances that contain ozone-depleting refrigerants be certified in proper refrigerant handling techniques. These regulations were revised in the fall of 2016 to address HFCs, HFOs, newly adjusted allowable leak rates, and expanded record keeping guidelines. The ESCO Institute's EPA Section 608 Certification Program has been revised to incorporate these new regulations.
