California Regulation Prohibits use of HFCs in New Products and Applications

The California Air Resources Board (CARB) adopted a regulation prohibiting the use of HFCs in certain stationary refrigeration and foam end-uses.

CARB was relying substantially on the U.S. EPA’s Significant New Alternatives Policy (SNAP) rules to help meet California’s emission reduction goals for HFCs. The board said the action was taken to preserve and continue in California some of the EPA’s prior prohibitions on HFCs, which have since been affected by a court ruling limiting EPA’s authority in this area.

The regulation preserves emission reductions from specific sectors with past or upcoming compliance deadlines. Many manufacturers are already transitioning away from HFCs for various products and uses. 

The regulation applies mostly to equipment manufacturers, which cannot use prohibited HFCs in new refrigeration equipment or foams in California for the following end-uses:

  • Supermarkets and Remote Condensing Units
  • Refrigerated Food Processing & Dispensing Equipment
  • Stand-alone, or small self-contained refrigeration units;
  • Refrigerated vending machines; and
  • Foams used in buildings and other places.

Also under the new CARB regulations, manufacturers are responsible for a disclosure statement that must certify the product uses only compliant refrigerants or foam expansion agents.
