Frequently Asked Questions

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 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.
