The U.S. Environmental Protection Agency (EPA) has issued regulations that set phased-in compliance deadlines restricting the use of certain hydrofluorocarbon sprays and their transportation in 40 specific sectors or subsectors of industry. This potentially includes some airframe and aircraft parts manufacturing processes, aircraft maintenance, and use of the sprays for cargo or air conditioning components in aircraft.

In addition to limiting the use of the agent, the rulemaking also provides a process for submitting technology transition petitions; establishes recordkeeping and reporting requirements; and addresses certain other elements related to the effective implementation of the American Innovation and Manufacturing Act of 2020.
