Since proposing the Clean Air Rule, we've been actively seeking feedback that would help inform and shape the proposal.

We are getting helpful and constructive ideas on how best to move the rule forward. We've considered many potential changes and refinements to the rule.

Let your voice be heard

In-person hearings

These hearings will begin with a short presentation followed by a question and answer session. The hearing will start after the Q&A session. That is when Ecology will accept oral comments. Staff will also accept written comments.
