On March 11, the U.S. Environmental Protection Agency completed an important rulemaking under Title VI of the Clean Air Act Amendments of 1990, revising its requirements applicable to the management of refrigerants in appliances and industrial process refrigeration.

The rulemaking corrects what the EPA states was an incorrect Obama-era interpretation of the Clean Air Act, that would have allowed the agency to issue sweeping and costly regulations for refrigerants that companies had invested in to alleviate the problem of ozone-layer depletion pursuant to the 1987 Montreal Protocol.

Joining a growing chorus of states, several Northeastern states, including Massachusetts, Maine and Rhode Island, have recently announced their intentions to impose a ban on the use of hydrofluorocarbons (HFCs). The looming regulatory actions by these states are generally anticipated to follow an HFC ban rulemaking model established by the members of the US Climate Alliance.[1] It remains to be seen, however, whether the states will look to additional regulatory options, as it was a worldwide product ban in the late 1980s that inadvertently set the stage to now limit alternatives containing HFCs due to their climate forcing potential as a greenhouse gas (GHG).
