Ecology proposed the Clean Air Rule on May 31, 2016. Since then, we have been collecting comments, questions, suggestions, and feedback from the public, regulated industries, and environmental advocates.

We held an informational webinar and also offered the public a chance to comment on the proposal at two in-person hearings and two webinars. We also accepted comments through our web site, emails, and even fax. Recordings are available on our website.

Next steps

The public comment period closed July 22 and no new comments are being accepted. We are currently reviewing the more than 2,000 comments we received and preparing an official response.

The official response is called a "Concise Explanatory Statement" and will include the comments about the proposed rule and our response to each. If you would like to receive notice when the CES is published, please use the sign up button on this page.

If you have questions about the review process, please send an email to
