Semiconductor Equipment & Materials International v. EPA

Petitions for review were filed in the D.C. Circuit Court of Appeals challenging EPA’s final rule restricting use of certain hydrofluorocarbons (HFCs) with high global warming potentials in certain sectors and subsectors pursuant to the American Innovation and Manufacturing Act of 2020. The rule restricts HFCs in approximately 40 subsectors in the refrigeration, air conditioning, heat pump, foam, and aerosol sectors. The rule also establishes process and information requirements for the public to submit petitions requesting that EPA initiate rulemakings to restrict HFCs in certain sectors and subsectors.
