Pursuant to the U.S. Environmental Protection Agency's Significant New Alternatives Policy program, this action lists several substitutes as acceptable, subject to use conditions, for retail food refrigeration, commercial ice machines, industrial process refrigeration, cold storage warehouses, and ice skating rinks. Through this action, EPA is incorporating by reference standards which establish requirements for commercial refrigerating appliances and commercial ice machines, safe use of flammable refrigerants, and safe design, construction, installation, and operation of refrigeration systems. This action also exempts propane, in the refrigerated food processing and dispensing end-use, from the prohibition under the Clean Air Act (CAA) on knowingly venting, releasing, or disposing of substitute refrigerants in the course of maintaining, servicing, repairing or disposing of an appliance or industrial process refrigeration, as the Administrator is determining, on the basis of existing evidence, that such venting, release, or disposal of this substance in this end-use does not pose a threat to the environment.This rule is effective 15 July 2024.
