California adopted SB 1013 enacting vacated portions of EPA’s SNAP Rules 20 and 21, and prohibiting certain HFCs in aerosol propellants, chillers, foam, and stationary refrigeration end-uses. The California Air Resources Board (CARB) is also developing a rulemaking with additional HFC emissions reduction measures for chillers, stationary air conditioning equipment and stationary refrigeration equipment. CARB presented the proposals and draft regulatory text during a public workshop on January 30, 2020 and on July 22, 2020. The proposed regulation order was approved by the CARB Board on December 10, 2020.
