Rulemaking Announcement Phase
Ecology is amending an existing rule. During the rule development process, Ecology will ask for feedback from stakeholders on key issues
related to this rulemaking and proposed rule language changes. Ecology will post rulemaking information on our rulemaking website, 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.
General answers about Ecology's rulemaking process are on the Laws & Rules
Frequently Asked Questions page.
