On June 20, 2023, the U.S. Court of Appeals for the District of Columbia Circuit concluded that EPA in relying on subsection (e)(2)(B) of the AIM Act had not identified a provision of the AIM Act giving it authority to ban disposable cylinders or to require a QR-code tracking system. As a result of this conclusion, the D.C. Circuit vacated the parts of the HFC Allocation Framework Rule related to the QR-code and disposable cylinder ban and remanded to the Agency. On August 23, 2023, the D.C. Circuit issued its formal mandate making their judgment final and effective. Consistent with the D.C. Circuit’s decision, this action removes from 40 CFR part 84 certain regulatory provisions that prohibit use of disposable cylinders, implement the cylinder tracking system, and create auditing obligations related to the cylinder tracking system.
