USA - Phasedown of Hydrofluorocarbons: Excluding Road and Intermodal Container Transport Refrigeration Units From the Hydrofluorocarbon Leak Repair Requirements

The EPA is proposing to clarify that road and intermodal container transport refrigeration units (TRUs) are exempt from the AIM Act leak repair requirements.

The existing 2024 HFC management rule, notified as G/TBT/N/USA/2242/Add.2, introduced leak repair obligations for refrigerant-containing appliances with a charge size of 15 pounds or more that use HFCs or certain HFC substitutes. EPA states that it originally intended TRUs to be exempt, and this proposal is limited to confirming that exemption; it does not propose changes to any other part of the 2024 rule.
