On November 21, 2019, Ecology adopted a second emergency rule and is working on the permanent rule: Chapter 173-443 WAC, Hydrofluorocarbons. The purpose of this rulemaking is to establish requirements to move away from hydrofluorocarbons (HFCs). HFCs are powerful greenhouse gases that are made up of hydrogen, fluorine, and carbon. This is similar to rules that EPA and other states have adopted or are adopting.
The emergency rule requires manufacturers, importers, and distributors to notify Ecology about their products and equipment that contain hydrofluorocarbons:
The permanent rule requires manufacturers, importers, and distributors to:
- Notify Ecology about their products and equipment that contain hydrofluorocarbons — due when new restrictions apply (2021-2024).
- Label the product or equipment that contains hydrofluorocarbons.
