Documents for review
We write rules to implement and enforce state and federal environmental laws and rules. We 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.
