We invite you to participate in our rulemaking process. Rule chapters listed below indicate Ecology's intentions for rulemaking on that chapter. These links will take you to the rulemaking web page which contains information including documents, timelines, and contact information.
You will see rules in various stages of the rulemaking process.
- Rulemaking that has been officially filed with the Washington State Legislature's Code Revisers Office (filed a CR-101 form), known as "open rulemaking."
- Ecology programs that are undergoing an exploratory process for rulemaking, known as "exploratory rulemaking."
See our Frequently Asked Questions for more information relating to the rulemaking process.
