Summary

The EPA Administrator must write rules by November 15, 1991 about how motor vehicle air conditioners are serviced. Key words: refrigerant means class I or II refrigerants (and, starting November 15, 1995, also substitute substances); approved refrigerant recycling equipment means equipment certified to meet standards at least as strict as SAE J‑1990; properly using means using that equipment to meet standards like SAE J‑1989; properly trained and certified means workers trained and certified under programs like ASE or MACS that meet SAE J‑1989. Starting January 1, 1992, anyone who services cars for pay cannot work on an air conditioner’s refrigerant unless they use approved recycling equipment correctly and are properly trained and certified. Shops that serviced fewer than 100 car air conditioners in 1990 can delay those rules until January 1, 1993 if they tell the EPA by January 1, 1992. By November 15, 1992 each paid service provider must certify to the EPA either that they have the approved equipment and trained staff or that they serviced fewer than 100 systems in 1991; those who claimed the under‑100 exception must submit the equipment-and-training certification by January 1, 1993. Certifications must include name, address, equipment serial numbers, and a responsible signature. Also, beginning November 15, 1992 it is illegal to sell or ship interstate refrigerant in containers under 20 pounds except to certified service providers who follow these rules.

(a)Regulations
Within 1 year after November 15, 1990, the Administrator shall promulgate regulations in accordance with this section establishing standards and requirements regarding the servicing of motor vehicle air conditioners.
(b)Definitions
As used in this section
(1)
(2)(A)The term “approved refrigerant recycling equipment” means equipment certified by the Administrator (or an independent standards testing organization approved by the Administrator) to meet the standards established by the Administrator and applicable to equipment for the extraction and reclamation of refrigerant from motor vehicle air conditioners. Such standards shall, at a minimum, be at least as stringent as the standards of the Society of Automotive Engineers in effect as of November 15, 1990, and applicable to such equipment (SAE standard J–1990).
(B)Equipment purchased before the proposal of regulations under this section shall be considered certified if it is substantially identical to equipment certified as provided in subparagraph (A).
(3)The term “properly using” means, with respect to approved refrigerant recycling equipment, using such equipment in conformity with standards established by the Administrator and applicable to the use of such equipment. Such standards shall, at a minimum, be at least as stringent as the standards of the Society of Automotive Engineers in effect as of November 15, 1990, and applicable to the use of such equipment (SAE standard J–1989).
(4)The term “properly trained and certified” means training and certification in the proper use of approved refrigerant recycling equipment for motor vehicle air conditioners in conformity with standards established by the Administrator and applicable to the performance of service on motor vehicle air conditioners. Such standards shall, at a minimum, be at least as stringent as specified, as of November 15, 1990, in SAE standard J–1989 under the certification program of the National Institute for Automotive Service Excellence (ASE) or under a similar program such as the training and certification program of the Mobile Air Conditioning Society (MACS).
(c)Servicing motor vehicle air conditioners
Effective January 1, 1992, 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 recycling equipment and no such person may perform such service unless such person has been properly trained and certified. The requirements of the previous sentence shall not apply until January 1, 1993 in the case of a person repairing or servicing motor vehicles for consideration at an entity which performed service on fewer than 100 motor vehicle air conditioners during calendar year 1990 and if such person so certifies, pursuant to subsection (d)(2), to the Administrator by January 1, 1992.
(d)Certification
(1)Effective 2 years after November 15, 1990, each person performing service on motor vehicle air conditioners for consideration shall certify to the Administrator either—
(A)that such person has acquired, and is properly using, approved refrigerant recycling equipment in service on motor vehicle air conditioners involving refrigerant and that each individual authorized by such person to perform such service is properly trained and certified; or
(B)that such person is performing such service at an entity which serviced fewer than 100 motor vehicle air conditioners in 1991.
(2)Effective January 1, 1993, each person who certified under paragraph (1)(B) shall submit a certification under paragraph (1)(A).
(3)Each certification under this subsection shall contain the name and address of the person certifying under this subsection and the serial number of each unit of approved recycling equipment acquired by such person and shall be signed and attested by the owner or another responsible officer. Certifications under paragraph (1)(A) may be made by submitting the required information to the Administrator on a standard form provided by the manufacturer of certified refrigerant recycling equipment.
(e)Small containers of class I or class II substances
Effective 2 years after November 15, 1990, it shall be unlawful for any person to sell or distribute, or offer for sale or distribution, in interstate commerce to any person (other than a person performing service for consideration on motor vehicle air-conditioning systems in compliance with this section) any class I or class II substance that is suitable for use as a refrigerant in a motor vehicle air-conditioning system and that is in a container which contains less than 20 pounds of such refrigerant.
