Rule Making

Water Quality Program Rulemaking

Ecology follows a three-phase rulemaking process: announcement, proposal, and adoption. For each phase of the process we update the individual rulemaking page and send notice to interested parties. We also file notice in the Washington State Register. To learn more about Ecology’s rulemaking process visit the Frequently Asked Questions.
