(1) To achieve the transition to refrigerants with low global warming potential and ultra-low global warming potential by 2035, accounting for distinctions among different types of equipment and appliances for hydrofluorocarbon-using sectors and subsectors and the timelines needed for each sector or subsector to complete such a transition, the department shall adopt rules, informed by the work and the report of the task force, to require low global warming potential or ultra-low global warming potential alternatives to hydrofluorocarbons in a sector unless it is not practicable for entities in the sector to comply with the requirement.

(2) The department may not issue a proposed rule under chapter 34.05 RCW related to subsection (1) of this section until January 1, 2028.

(3) The department may combine rule making under this section with rule making authorized under RCW 70A.60.100 for purposes of efficiency.
