The D.C. Circuit Court of Appeals vacated two parts of EPA’s regulations implementing the phasedown of hydrofluorocarbons (HFCs) mandated by the American Innovation and Manufacturing Act but rejected other challenges to the regulations. The court concluded that the statute did not authorize EPA either to mandate that refillable cylinders be used to transport HFCs or to establish a certification and tracking system for HFC distribution that required that a QR code be affixed to each container to document a valid certification identification. (Judge Pillard dissented from this portion of the decision, finding that the measures fell within EPA’s congressionally delegated authority to “ensure” compliance with the phasedown schedule.) The court upheld other challenged aspects of the rule, holding that the statute gave EPA authority to regulate HFCs within blends and finding that it could not consider an argument that the statute violated the nondelegation doctrine because the petitioner did not raise this argument before EPA.
