Policy and purpose.

(1) Ecology's policy under chapters 70A.15 and 43.21A RCW is to provide for the systematic control of air pollution from air contaminant sources. Ecology's policy under chapter 70A.45 RCW is to reduce the emissions of greenhouse gases.
(2) This chapter establishes requirements for the transition to less damaging HFCs or suitable substitutes in the air conditioning and refrigeration, aerosol propellant, and foam end-use categories in Washington in a manner similar to rules adopted under EPA's Significant New Alternative Policy (SNAP) program and HFC rules adopted or proposed for adoption by other states around the country (RCW 70A.45.080).
