On July 13, 2023, the Washington State Department of Ecology (Ecology) published proposed amendments to Chapter 173-443 WAC, Hydrofluorocarbons (HFCs). Key provisions of the Proposed Rule include:
- Establishing maximum global warming potential (GWP) thresholds for HFCs used in new stationary refrigeration and air conditioning equipment, small cans of refrigerant, and certain nonessential consumer aerosol products;
- Establishing 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; and
- Establishing required service practices for technicians who service stationary refrigeration and air conditioning systems.
