On December 27, 2018 the California Office of Administrative Law approved the adoption of regulations prohibiting the use of certain HFCs in stationary refrigeration and Foam End-Uses already adopted by the California Air Resources Board. The rules incorporating and expanding on the Federal Clean Air Act’s Significant New Alternatives Policy (SNAP) in the state of California can be found in CCR Title 17. This new rulemaking creates a prohibition on the use of HFCs in stationary refrigeration in retail food refrigeration, vending machines and foam end-uses. These rules were passed to codify the prohibitions in California law in case they were nullified on the federal level. The rules are effective immediately.
