Section 609 of the Clean Air Act Amendments of 1990 (Act) provides general guidelines for the recovery and recycling of motor vehicle air conditioners. It states that "no person repairing or servicing motor vehicles for consideration may perform any service on a motor vehicle air conditioner involving the refrigerant for such air conditioner without properly using approved refrigerant recovery and/or recovery and recycling equipment (hereafter referred to as "refrigerant handling equipment") and no such person may perform such service unless such person has been properly trained and certified." In 1992, EPA developed regulations under section 609 that were published in 57 FR 31240, and codified at 40 CFR Subpart B (Section 82.30 et seq.). The information required to be collected under the Section 609 regulations is: approved refrigerant handling equipment; approved independent standards testing organizations; technician training and certification; and certification, reporting and recordkeeping.
