There are many opportunities to participate in the wide-ranging programs within DEQ’s Air Quality Bureau. We are frequently requesting public comment on a number of topics, including proposed rulemakings, SIP submittals, and industrial permits both large and small. On our “Public Comment on Rules” page, you will see opportunities to learn about and comment on upcoming regulatory actions both in the air bureau and across all programs at DEQ. On our “Public Notice on Permits” page, you can will find all Montana Air Quality Permits and Title V permits that are currently undergoing a public comment period, appeal period, or EPA review. On our “Notification of Source Locations“ page, you can find out where registered gravel crushing, concrete, and asphalt plants have proposed to locate. Any and all stakeholders are encouraged to participate explore our "Clean Air Act Advisory Committee (CAAAC)" page. Through a collaborative two-way exchange of information, CAAAC advises DEQ on a wide range of air quality issues including establishment and implementation of laws and rules; program funding; compliance assistance; and regional air quality issues, impacts, and challenges. Your participation in CAAAC is encouraged. As always, you can contact us directly with any suggestions or concerns at 406-444-3490.
