Program Contacts

In an emergency, make sure you notify 911 and your local authorities first. Then proceed to contact our program through the DES duty officer program at 406-324-4777, which notifies the DEQ duty officer program, or contact our offices directly during business hours. Please keep trying until you speak to a live person who can get you assistance as it is being requested.
