Clean Fuels Program Rule, Chapter 173-446 WAC

Public hearing — online

Aug. 23, 2022, 10 a.m., online webinar

Ecology is holding a public hearing about the rulemaking for Clean Fuels Program Rule, Chapter 173-446 WAC.

Ecology is starting rulemaking for a new rule, Chapter 173-424 WAC, Clean Fuels Program Rule and proposes to update Chapter 173-455 WAC, Air Quality Fee Rule.

This new rule will:

  • Establish carbon intensity standards for transportation fuels used in Washington.
  • Assign compliance obligations to fuels with carbon intensities that exceed the standard.
  • Establish compliance methods including assigning credits to fuels that have carbon intensities below the standard.

This rulemaking will also update Chapter 173-455 WAC to establish the process for setting fees to recover the cost of developing and implementing the program.

We write rules to implement and enforce state and federal environmental laws and rules.  Ecology follows a 3-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.
