EPA to abandon restrictions against use of hydrofluorocarbons as refrigerant in appliances

The Trump administration is planning to  do away with an Obama-era regulation that restricted a known greenhouse gas from being used as a refrigerant in household appliances. The Environmental Protection Agency (EPA) late Wednesday announced it's proposing a rule to rescind a 2016 regulation that would have phased out the use of hydrofluorocarbons (HFCs) in appliances. The chemical is frequently used as a refrigerant substitute in air conditioners and refrigerators. EPA said the new rule is based off the agency’s own determination that the previous rule “exceeded its statutory authority” by extending a refrigerant management requirement meant for ozone depleting substitutes to the gas, which in itself does not contribute to ozone depletion. The agency added that the new rule does not affect current requirements for other ozone-depleting refrigerants. Sensing a legal challenge may hinder the EPA’s implementation of the 2016 rule, a bipartisan group of senators introduced a bill in February that would give the agency the authority to regulate the greenhouse gas–causing chemical due to its air pollution, not relying on a connection to ozone depletion.At the time Sen. Tom Carper (D-Del.) said the bill, called the American Innovation and Manufacturing Act, “continues support for American development and manufacturing of next-generation HFC-alternatives, while also protecting our environment and helping the U.S. meet its obligations under the amended Montreal Protocol — a true win-win.”
