Air Quality Program Rule Making

Ecology has a process that we follow for rule making. For each phase of the process, Ecology updates the information on our web site and sends notice to interested parties. We also file notice with the Office of the Code Reviser which is published in the Washington State Register. To learn more about Ecology’s rule-making process, read the Frequently Asked Questions.

The Air Quality Program is currently working on the rule making listed below. The most recent rules are listed first.
