EPA Announces New List of Acceptable Substitutes for Air Conditioning and Propellants

The Environmental Protection Agency (EPA) has issued a notice expanding the list of acceptable substitutes for ozone depleting substances under their Significant New Alternatives Policy (SNAP). The substitutes are for use in several different sectors including bus and passenger train air conditioning. The majority of the acceptability decisions find substitutes acceptable as alternatives to the class II ozone depleting substances hydrochlorofluorocarbon or HCFC-22, HCFC-142b and blends containing one or both of these substances. EPA is also finding one of the alternatives, HFO-1234ze, acceptable as a substitute for CFC-11 in the aerosol propellant end use.

According to the agency, “The listing of additional refrigerant alternatives as acceptable will provide users in the refrigeration and air-conditioning sector with more options for replacing HFCFC-22 and HCFC-142b, which pursuant to EPA’s phase-out regulations, may generally be used only as a refrigerant to service equipment manufactured before Jan. 1, 2010.”
