Clean Energy Transformation Rule, Chapter 173-444 WAC

Proposed rulemaking

Sept. 2, 2020 - Oct. 14, 2020, 11:59 p.m.

Ecology is proposing a new rule — Chapter 173-444 WAC, Clean Energy Transformation Rule — to help reduce greenhouse gases in Washington by transitioning away from electricity sources that depend on fossil fuels.

The proposed rule will:

  • Establish a process to determine what types of energy transformation projects may be eligible to meet the Clean Energy Transformation Act.
  • Establish a process and requirements to develop standards, methodologies, and procedures to evaluate energy transformation projects.
  • Provide methods to assign greenhouse gas emission factors for electricity.

Documents for review


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.
