Environmental Protection Agency
The U.S. Environmental Protection Agency (EPA) is proposing an exemption for road and intermodal container transport refrigeration units (TRUs) from the leak repair requirements established under the American Innovation and Manufacturing (AIM) Act. In the final rule "Phasedown of Hydrofluorocarbons: Management of Certain Hydrofluorocarbons and Substitutes Under the American Innovation and Manufacturing Act of 2020," the EPA established, among other provisions, leak repair requirements for refrigerant-containing appliances with a charge size of 15 pounds or more that contain a hydrofluorocarbon (HFC) or certain substitutes for HFCs. The EPA intended to exempt refrigerant-containing road and intermodal container TRUs from the leak repair requirements and is issuing this proposal to clarify the applicability of these requirements. The EPA is not proposing other amendments or taking comment on any other aspects of the 2024 "Phasedown of Hydrofluorocarbons: Management of Certain Hydrofluorocarbons and Substitutes Under the American Innovation and Manufacturing Act of 2020."
