Chapters 173-443 and 173-455 WAC – Hydrofluorocarbons (HFCs)

On November 30, 2023, Ecology adopted two rules:

The adopted rule:

  • Establishes maximum global warming potential (GWP) thresholds for hydrofluorocarbons used in new stationary refrigeration and air conditioning equipment, small cans of refrigerant, and certain nonessential consumer aerosol products.
  • Establishes a refrigerant management program with registration, leak inspection, leak repair, recordkeeping, and reporting requirements for owners or operators of large stationary refrigeration and air conditioning systems.
  • Establishes required service practices for technicians who service stationary refrigeration and air conditioning systems.
  • Amend sproduct labeling and disclosure requirements.
  • Establishes new labeling and recordkeeping requirements.
  • Updates Chapter 173-443 WAC to reflect other changes in the law.
  • Revises the title of the chapter.

A new section in Chapter 173-455 WAC establishes fees and a process for fee updates to cover the costs of implementing and enforcing the refrigerant management program.
