Ecology adopted a rule in 2019 to transition away from using potent greenhouse gases known as hydrofluorocarbons (or HFCs) in products and equipment starting Jan. 1, 2020.
HFCs are chemicals made up of hydrogen, fluorine, and carbon. They are commonly used in air conditioning and refrigeration, in producing insulating foams, and as propellants. These greenhouse gases are thousands of times more powerful than carbon dioxide.
HFCs were designed specifically because they were thought to be less harmful to the earth's protective ozone layer. Now, HFCs are rapidly building up in the atmosphere. If their use isn't stopped, HFC emissions will increase to 7–19 percent of global greenhouse gas emissions by 2050. In Washington, HFCs account for about 4 percent of overall greenhouse gas emissions.
All manufacturers must notify us about the status of each product class using restricted HFCs.
Status updates are due within 120 days of a product restriction date. For example, if a product were restricted on Jan. 1, then the status update for that product would be due by April 30 of that same year.
To report your status update:
- Fill out the notification form using Adobe Reader. (Do not use Adobe Pro.)
- Check “update” instead of “initial notification.”
- Check the year you are providing the update.
- Submit your completed notification form using our online reporting system.
- Follow the instructions to register for a Secure Access Washington (SAW) account. You must have a SAW account to submit your notification form.
By Dec. 31, 2019, all manufacturers were required to notify us about the status of each product class using restricted HFCs.
The restrictions go into effect at different times for each product category:
- Jan. 1, 2020 — propellants, rigid polyurethane, spray insulating foam, and new supermarket refrigeration systems
- Jan. 1, 2021 — new refrigerated food processing and dispensing equipment, and compact residential refrigerators
- Jan. 1, 2022 — new residential refrigerators, and new and existing vending machine.
- Jan. 1, 2023 — new uses in cold-storage warehouses and built-in residential refrigerators
- Jan. 1, 2024 — new uses in centrifugal and positive displacement industrial chillers
* Refer to the law for the full list.
Complying with Washington's HFC law
The law focuses on reducing the use of HFCs in new equipment, so manufacturers and distributors must meet these requirements. In most cases, residents and businesses that own or use equipment containing HFCs will not need to do anything to obey the law.
