For each calendar year the Air Compliance Section of the Air Resources Management Bureau compiles an estimated emission inventory of the stationary point sources in the state.  This inventory is public information and is available from the Montana Department of Environmental Quality or the United States Environmental Protection Agency (USEPA) in October of each year.

If you have specific questions regarding a point source emission inventory, please contact us.

The Air Compliance Program is responsible for administering those portions of the Clean Air Act (CAA) of Montana (Section 75-2-101 et seq., MCA) and companion regulations pertaining to compliance of air emissions from various types of facilities including delegated federal regulations.

Air Compliance Program Duties

  • Regulating emissions of criteria and hazardous pollutants regulated in the CAA and ACA in potentially environmentally sensitive, heavily industrialized, heavily populated and diverse topographic environments throughout the entire state;
  • Conducting regular compliance inspections of all operating facilities and reviewing compliance reports;
  • Recommending enforcement actions to the bureau chief;
  • Identifying the need for and reviewing draft legislation and administrative rules;
  • Actively participating in the development of department policy regarding air quality standards and compliance processes;
  • Coordinating and participating in a variety of technical, public and general information meetings with other state and federal agencies, special interest groups, landowners, private business and the general public regarding compliance with air quality standards;
  • Collecting and managing extensive correspondence, map and data files, pertaining to air emissions using, to the extent available, state-of-the-art computer technology;
  • Gathering a wide diversity of information on emissions, emission controls, regulation and the related fields - engineering, chemistry, computer programs, etc. We then use and disseminate the information to industry, government agencies and the general public.

Were the Air Quality Annual Fees changed? 

  • No, the annual air quality fees remain the same as last year.

What are the new fees?

  • Stationary facilities that hold a Title V Operating Permit and/or a Montana Air Quality Permit are assessed an annual fee of $900 plus a fee of $44.35 for each ton of PM-10, sulfur dioxide, lead, oxides of nitrogen, and volatile organic compounds emitted into the atmosphere. As an example, if a facility released 100 tons of the listed air pollutants during 2018, the amount owed would be 100 x $44.35 ($4,435) plus the annual fee of $900 for a total of $5,335.
  • Registered oil and gas facilities pay an annual fee of $850 with no additional per ton fee.
  • Unregistered portable facilities pay an annual fee of $800 with no additional per ton fee.
  • Registered portable facility fees are currently being proposed before the Board of Environmental Quality. These bills will be mailed in December 2020.

What authority does the Department of Environmental Quality rely on to collect air quality operating fees?

  • 75-2-220, Montana Code Annotated (MCA), and
  • Administrative Rules of Montana (ARM) 17.8.505

How are the collected fees used?

  • The fees collected are used to cover the costs of developing, implementing, and administering air quality permitting and registration requirements.

Which facilities are required to pay air quality fees?

  • A facility that held a permit or registration after March 1, 2020, is required to pay fees.
  • Regulated sources that revoked their permit or deregisterd a facility, but that did so after March 1, 2020, are still subject to the 2019 fee assessment.

Applying the formula given and using the amounts listed on my bill, my calculated total amount does not match with the amount shown on the bill.   Why did that happen?

  • The bill displays only two decimal points for the tons of emissions, however, the amount used in the calculation uses the amount of emissions out to four decimal points. As an example, in one case last year, the bill showed 40.50 tons of emissions but the amount used in the calculation was 40.5021 resulting in a difference of 8 cents in the amount the facility was charged. In another instance, the bill showed 0 (zero) pounds of emissions but using 4 decimal places in the calculation resulted in a charge.

How do I submit a payment?

  • A payment coupon is enclosed with your bill.
  • You have several options available for submitting your payment:
    • online by credit card, debit card, or e-check at: https://deq.mt.gov/about/index Scroll to middle of page and click on "Pay a Bill"
    • by mailing a check to:  DEQ, Financial Services Office - PO Box 200901  -  Helena, MT 59620-0901

I don't see the answer to my question here, who do I contact?

  • You may call the Air Quality Bureau at the Montana Department of Environmental Quality at (406) 444-3490 or
  • Send an email to: Air Quality Support Services or
  • Write to us: Montana DEQ - Air, Energy and Mining Division - Air Quality Bureau - PO Box 200901 - Helena, MT 59620-0901
