Chapters 173-443 and Chapter 173-455 WAC

Ecology proposes to update two rules:

This rulemaking may:

  • Establish maximum global warming potential (GWP) thresholds for hydrofluorocarbons used in new stationary refrigeration and air conditioning equipment.
  • Establish a refrigerant management program with registration, leak detection, and reporting requirements for certain stationary refrigeration and air conditioning systems.
  • Amend product labeling and disclosure requirements.
  • Establish fees to support the refrigerant management program.
  • Update Chapter 173-443 WAC to reflect other changes in the law.
