EPA Approves Hydrocarbon Refrigerants for Commercial and Household Use
"WASHINGTON, DC -- The U.S. Environmental Protection Agency [Wednesday] issued a rule making greener refrigeration gases legal in household refrigerators and some commercial freezers."
"The agency added three hydrocarbons as acceptable alternatives in household and small commercial refrigerators and freezers through EPA's Significant New Alternatives Policy program, SNAP, which evaluates substitute chemicals and technologies for ozone-depleting substances under the Clean Air Act.
The new rule legalizes the hydrocarbons propane, isobutane, and a chemical known as R-441A as refrigerants."Source: ENS, 12/16/2011
