Complaint or Spill Reporting

Information obtained from citizen reports is an integral part of the department's investigation of potential violations of Montana's environmental laws.  If you observe some activity that may harm the environment or cause a threat to human health, you can report it to the DEQ Enforcement Division for investigation.  The Enforcement Division will investigate all legitimate complaints to determine if there is a violation of Montana environmental laws.

You can report information to the Enforcement Division by calling (406) 444-0379, or by filling out a form below. You can fax the completed form to (406) 444-1923 or mail it to: Montana Department of Environmental Quality Enforcement Division, Complaint Coordinator, P.O. Box 200901 Helena, Montana 59620-0901, or email the completed form to Rich Jost.
