All Board meetings are open to the public; only Executive Sessions are closed. If you would like to speak to the Board about an air quality issue that is not on the agenda, there is a comment portion for the public at the beginning of every meeting (depending on how many people present would like to address the Board, you usually have approximately 3-5 minutes to speak).
When there are regulation changes being proposed during a public hearing, there will be an opportunity during that portion of the agenda to speak to the Board specifically about the proposed regulation changes. You will be advised at that time how much time you will be allotted to make your comments.
