Rule Making

Chapter 173-407 WAC
Carbon Dioxide Mitigation Program, Greenhouse Gases Emissions Performance Standard and Sequestration Plans and Programs for Thermal Electric Generating Facilities

Public Involvement

Ecology is amending an existing rule. During the rule development process, Ecology asks for stakeholder feedback about key issues related to this rulemaking and proposed rule language changes. We post rulemaking information on our rulemaking web page, hold stakeholder meetings, and maintain and use email distribution lists to keep interested parties informed. During the public comment period, Ecology will hold at least one public hearing.

Interested parties can participate in the development of the proposed rule through stakeholder meetings, by contacting Ecology staff directly, and by commenting on the proposed rule.
