Protection of Stratospheric Ozone: Revision to References for Refrigeration and Air Conditioning
The U.S. Environmental Protection Agency (EPA) is proposing to modify the use conditions required for use of three flammable refrigerants, isobutane (R-600a), propane (R-290), and R-441A, in new household refrigerators, freezers, and combination refrigerators and freezers under the Significant New Alternatives Policy (SNAP) program.
The use conditions, which address safe use of flammable refrigerants, would reflect the incorporation by reference of an updated standard from Underwriters Laboratories. In the "Rules and Regulations" section of this Federal Register, the U.S. EPA is modifying these use conditions as a direct final rule without a prior proposed rule. If no adverse comment are received, the U.S. EPA we will not take further action on this proposed rule.
