The first brief was filed in April the federal case against a new Environmental Protection Agency (EPA) rule that would ban the use of non-refillable refrigerant cylinders by 2025 and require refillable cylinders to be tracked using QR codes.
The brief, filed by lawyers for three trade associations and the only U.S. manufacturer of refrigerant cylinders, argues that the EPA overstepped its authority in issuing the rules, which were finalized last fall as part of the EPA’s guidelines for phasing down the use of hydrofluorocarbon (HFC) refrigerants, which are considered greenhouse gases that contribute to global warming.
