Hydrofluorocarbons (HFCs) Rule

Proposed rulemaking

June 16, 2020 - July 28, 2020, 11:59 p.m.

Ecology is proposing a new rule — Chapter 173-443 WAC, Hydrofluorocarbons (HFCs) — to help reduce greenhouse gases in Washington by transitioning to the use of less-damaging hydrofluorocarbons or substitutes in aerosol propellants, foams, refrigeration, and air conditioning.

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.

Documents for review

Background

We write rules to implement and enforce state and federal environmental laws and rules. We follow a three-phase process for rulemaking:

  1. Announcement and development
  2. Proposal
  3. Adoption

For each phase of the process, we update the rulemaking web page and notify interested parties. We also file notice in the Washington State Register. To learn more about Ecology’s rulemaking process, read the Frequently Asked Questions.
