Hydrofluorocarbons HFCs American Innovation and Manufacturing AIM Environmental Protection Agency EPA WTO

On May 26, 2026, the U.S. Environmental Protection Agency (EPA) proposed exempting road and intermodal container transport refrigeration units (TRUs) from certain hydrofluorocarbon (HFC) leak repair requirements established under the American Innovation and Manufacturing (AIM) Act.

Proposed Exemption

Under the current regulations, refrigerant-containing equipment with a charge size of 15 pounds or more is subject to HFC leak repair requirements. EPA stated that it originally intended to exempt road and intermodal container TRUs from these requirements and has proposed this amendment to clarify the rule’s applicability.

Potential Impact

The proposed exemption applies specifically to transport refrigeration units used in road and intermodal freight transportation. EPA emphasized that this action is limited to clarifying the exemption and does not introduce any other changes to the 2024 HFC management rule.

Public Comment Period

Stakeholders may submit comments on the proposal until July 10, 2026. EPA will review the feedback received before making a final decision on the proposed exemption.
