regulations. Each county program is different. Click on a county for contact and website information. If you have questions about county programs or are interested in having one of these programs in your county, call 406-444-3490.

Advisory Councils

What is CAAAC?

The Clean Air Act Advisory Committee (CAAAC) is a stakeholder advisory group formed to enhance communication between the Montana Department of Environmental Quality (DEQ) and a diverse range of air quality stakeholders by developing working relationships centered on a two-way exchange of information. CAAAC advises DEQ on a wide range of air quality issues not limited to establishment and implementation of laws and rules; program funding; compliance assistance; and regional air quality issues, impacts, and challenges. Through regular meetings and email correspondence, DEQ presents information to and solicits feedback from members of CAAAC.
