Phasedown of Hydrofluorocarbons: Reconsideration of Certain Regulatory Requirements Promulgated Under the Technology Transitions Provisions of the American Innovation and Manufacturing Act of 2020

What it does

The U.S. Environmental Protection Agency (EPA) is finalizing changes to regulations promulgated under the Technology Transitions provision of the American Innovation and Manufacturing Act of 2020 (AIM Act), which authorizes the Administrator to restrict fully, partially, or on a graduated schedule, the use of a "regulated substance" in the sector or subsector in which they are used. This final rule addresses administrative petitions and input received from regulated industry and other interested parties relevant to requirements and restrictions across various refrigeration and air conditioning subsectors, including: refrigerated transport--intermodal containers; industrial process refrigeration and chillers for industrial process refrigeration used in semiconductor manufacturing; retail food supermarket systems; retail food remote condensing unit systems; cold storage warehouses; refrigerated laboratory centrifuges and laboratory shakers; and condensing units in residential and light commercial air conditioning and heat pumps. This final rule also allows the inventory of residential and light commercial air conditioning and heat pump equipment that was manufactured in the United States or imported into the United States before January 1, 2025, to continue to be installed.
