EPA is developing a rulemaking to establish requirements for management of certain hydrofluorocarbons (HFCs) and their substitutes under the American Innovation and Manufacturing (AIM) Act of 2020 (42 U.S.C. 7675). Specifically, EPA is considering a rulemaking under subsection (h) of the AIM Act to establish regulations to control, where appropriate, practices, processes, or activities regarding the servicing, repair, disposal, or installation of equipment, for the purpose of maximizing the reclamation and minimizing the release of certain HFCs from equipment and ensuring the safety of technicians and consumers. Among these practices, processes, and activities, EPA is considering applying leak repair requirements to certain equipment using HFCs and their substitutes as refrigerants in this rulemaking. EPA also intends to consider options to increase opportunities for reclaiming regulated substances used as refrigerants and potential approaches to coordinate regulations carrying out subsection (h) of the AIM Act with similar EPA regulations, such as the refrigerant management program established under Title VI of the Clean Air Act.
