§ 586 — Regulation of hydrofluorocarbons

(a) As used in this section:
(1) “Class I substance” and “class II substance” mean those substances listed in the 42 U.S.C. § 7671a, as it read on November 15, 1990 and Appendix A or B of Subpart A of 40 C.F.R. Part 82, as those read on January 3, 2017.
(2) “Hydrofluorocarbon” means a class of greenhouse gases that are saturated organic compounds containing hydrogen, fluorine, and carbon.
(3) “Residential consumer refrigeration product” has the same meaning as in Section 430.2 of Subpart A of 10 C.F.R. Part 430.
(4) “Retrofit” has the same meaning as in section 152 of Subpart F of 40 C.F.R. Part 82, as that section existed as of January 3, 2017.
(5) “Substitute” means a chemical, product, or alternative manufacturing process, whether new or retrofit, that is used to perform a function previously performed by a class I substance or class II substance and any substitute subsequently adopted to perform that function, including hydrofluorocarbons.
(b)(1) A person may not offer any product or equipment for sale, lease, or rent or install or otherwise cause any equipment or product to enter into commerce in Vermont if that equipment or product consists of, uses, or will use a substitute, as set forth in Appendix U or V, Subpart G of 40 C.F.R. Part 82, as those read on January 3, 2017, for the applications or end uses restricted by Appendix U or V, as those read on January 3, 2017, and consistent with the dates established in subdivision (4) of this subsection.
(2) Except where existing equipment is retrofit, nothing in this subsection requires a person that acquired a restricted product or equipment prior to an effective date of the restrictions in subdivision (4) of this subsection to cease use of that product or equipment.
(3) Products or equipment manufactured prior to an applicable effective date of the restrictions in subdivision (4) of this subsection may be sold, imported, exported, distributed, installed, and used after the specified effective date.
(4) The restrictions under subdivision (1) of this subsection shall take effect beginning:
(A) January 1, 2021, for propellants, rigid polyurethane applications and spray foam, flexible polyurethane, integral skin polyurethane, flexible polyurethane foam, polystyrene extruded sheet, polyolefin, phenolic insulation board and bunstock, supermarket systems, remote condensing units, stand-alone units, and vending machines;
(B) January 1, 2021, for refrigerated food processing and dispensing equipment, compact residential consumer refrigeration products, polystyrene extruded boardstock and billet, and rigid polyurethane low-pressure two component-spray foam;
(C) January 1, 2022, for residential consumer refrigeration products other than compact and built-in residential consumer refrigeration products;
(D) January 1, 2023, for cold storage warehouses and built-in residential consumer refrigeration products;
(E) January 1, 2024, for centrifugal chillers and positive displacement chillers;
(F) January 1, 2020, or the effective date of the restrictions identified in appendix U or V, Subpart G of 40 C.F.R. Part 82, as those read on January 3, 2017, whichever comes later, for all other applications and end uses for substitutes not covered by the categories listed in subdivisions (A) through (E) of this subsection (b);
(G) July 1, 2022, for refrigeration systems used in ice skating rinks; and
(H) January 1, 2023, for containers designed for consumer recharge of motor vehicle air conditioners that use substitutes prohibited under this section.
(c) The Secretary may adopt rules that include any of the following:
(1) The modification of the date of a prohibition established pursuant to subsection (b) of this section if the Secretary determines that the modified deadline meets both of the following criteria:
(A) reduces the overall risk to human health or the environment; and
(B) reflects the earliest date that a substitute is currently or potentially available.
(2) The prohibition on the use of any substitute if the Secretary determines that the prohibition meets both of the following criteria:
(A) reduces the overall risk to human health or the environment; and
(B) a lower-risk substitute is currently or potentially available.
(3) The creation of a list of approved substitutes, use conditions, or use limits, if any, and the addition or removal of substitutes, use conditions, or use limits to or from the list of approved substitutes if the Secretary determines those substitutes reduce the overall risk to human health and the environment.
(4) The creation of a list of exemptions from this section for medical uses of hydrofluorocarbons.
(d) If the U.S. Environmental Protection Agency approves a previously prohibited hydrofluorocarbon blend with a global warming potential of 750 or less for foam blowing of polystyrene extruded boardstock and billet and rigid polyurethane low-pressure two-component spray foam pursuant to the Significant New Alternatives Policy Program under section 7671(k) of the federal Clean Air Act (42 U.S.C. Sec. 7401 et seq.), the Secretary shall expeditiously propose a rule to conform to the requirements established under this section with that federal action.
(e) The Secretary of Administration shall include in Administrative Bulletin 3.5 a requirement that State procurement contracts shall not include products that contain hydrofluorocarbons, as prohibited in this section.
