Ecology is holding a public hearing about the rulemaking for Reporting of Emissions of Greenhouse Gases, Chapter 173-441 WAC.

This rulemaking:

  • Adds natural gas suppliers, carbon dioxide suppliers, and electric power entities to the existing greenhouse gas reporting program.
  • Replaces the existing transportation fuel supplier program with a program that is compatible with the Climate Commitment Act.
  • Updates greenhouse gas reporting requirements to support the Climate Commitment Act and facilitates program linkage with other jurisdictions.
  • Adds program elements to support the verification of greenhouse gas reporting data.
  • Modifies administrative provisions, such as deadlines and greenhouse gas reporting fees.
  • Includes requirements necessary to support the above items, the overall objectives of the statute or chapter, or the goals of the Climate Commitment Act. 
  • Makes administrative changes for correction or clarification.

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.
