(a) For purposes of this section, the following definitions apply: (1) âBulkâ has the same meaning as defined in Section 84.3 of Title 40 of the Code of Federal Regulations, as that regulation existed as of October 1, 2024. (2) âCertified reclaimed refrigerantâ means used (recovered) refrigerant that meets all of the following criteria: (A) Has been reclaimed by a refrigerant reclaimer certified by the United States Environmental Protection Agency from a previously operational appliance. (B) Meets all specifications in Appendix A to Subpart F (commencing with Section 82.150) of Part 82 of Title 40 of the Code of Federal Regulations, as those regulations existed as of October 1, 2024, as demonstrated by an analysis conducted to verify that it meets these specifications. (C) Contains no greater than 15 percent new hydrofluorocarbon refrigerant by weight to meet the specifications in Appendix A to Subpart F (commencing with Section 82.150) of Part 82 of Title 40 of the Code of Federal Regulations, as those regulations existed as of October 1, 2024, and has documentation prepared by a refrigerant reclaimer certified by the United States Environmental Protection Agency that supports that the reclaimed refrigerant does not exceed the maximum allowable new hydrofluorocarbon refrigerant content. (3) âHydrofluorocarbonsâ has the same meaning as âregulated substanceâ as defined in Section 84.3 of Title 40 of the Code of Federal Regulations, as that regulation existed as of October 1, 2024. (4) âGlobal warming potentialâ or âGWPâ is a measure of how much energy the emissions of one ton of a gas will absorb over a given period of time, relative to the emissions of one ton of carbon dioxide. âGlobal warming potentialâ or âGWPâ means the 100-year global warming potential values published by the Intergovernmental Panel on Climate Change (IPCC) in its Fourth Assessment Report (AR4) in 2007, and if a relevant value is not contained in AR4, âglobal warming potentialâ means the 100-year global warming potential values published by the IPCC in its Fifth Assessment Report (AR5) in 2013 or as determined by the state board in a regulation adopted pursuant to this section. (5) âLow GWPâ means GWP of less than 150. (6) âNew hydrofluorocarbon refrigerantâ means hydrofluorocarbon refrigerant that has not been previously used. (7) âPersonâ has the same meaning as defined in Section 39047. (8) âUltra-low GWPâ means GWP of less than 10. (b) (1) A person shall not offer for sale or distribution, or otherwise enter into commerce in the state, bulk hydrofluorocarbons or bulk blends containing hydrofluorocarbons that exceed any of the global warming potential limits as specified in paragraph (2), (3), or (4). (2) Beginning January 1, 2025, the global warming potential shall not exceed 2,200. (3) Beginning January 1, 2030, the global warming potential shall not exceed 1,500. (4) Beginning January 1, 2033, the global warming potential shall not exceed 750. (c) Nothing in this section shall restrict the authority of the state board to establish by regulation maximum allowable global warming potential levels for hydrofluorocarbons entered into commerce in the state below the maximum levels established in subdivision (b). (d) (1) The prohibitions established pursuant to subdivision (b) or (c) shall not apply to any of the following: (A) Certified reclaimed refrigerants. (B) (i) Hydrofluorocarbons that are exclusively for use in metered dose inhalers approved by the United States Food and Drug Administration for medical purposes. (ii) The exemption established pursuant to clause (i) shall become inoperative on December 27, 2030. (C) (i) Hydrofluorocarbons that are exclusively for use in very low temperature refrigeration or cooling designed to maintain temperatures below -58 degrees Fahrenheit (-50 degrees Celsius), including, but not limited to, medical and laboratory freezers, refrigerated transport, specialized
