Existing Facilities

The Air Quality Bureau at Montana DEQ has both permitting and registration programs for industry in Montana. Registered sources in Montana include oil and gas facilities, crushers and screens, concrete batch plants, and asphalt plants. All other industry would fall under our permitting program. Click below to find more information about existing permitting and registration sources, including what to do if a change of ownership occurs, how to enter annual emission inventory, and how to meet compliance requirements.

 

Introduction

Click on the source category on the left to find common questions for existing registered facilities. Here you will find required forms, guidance information, and frequently asked questions. If you can't find what you need please call us at 406-444-3490.

Oil and Gas

Some general guidance for registered oil or gas well facility operation is described below. More detailed rules can be found in the Administrative Rules of Montana (ARM) 17.8 Subchapter 17, Registration of Air Contaminant Sources.

  • Complete the Change of Ownership form and submit the form by email to: DEQ-ARMB-Admin@mt.gov
  • For an ownership change of multiple facilities, one form may be completed as long as a list or table that identifies each applicable facility by name and registration number is attached.

Yes, registered oil or gas well facilities may be inspected for compliance by the Department at their discretion.

  1. The owner or operator will be contacted the Department to schedule field inspection(s).
  2. The Department may request records for each facility inspected, such as compliance data showing hours of operation, production rates and corresponding emission levels.
  3. A company representative will be required to accompany the Department inspector to all facilities being inspected.
  4. Following the inspection(s) the owner or operator will receive an inspection report for each facility detailing compliance determinations and observations.
  5. If the facility was found to be out of compliance, the Department will notify the company of further potential actions.
  • Records showing daily hours of operation, production rates, and corresponding emissions must be recorded.
  • All records of monthly VOC leak inspections and repairs must be recorded.
  • These records must be maintained for at least five years, be available for inspection and submitted to the Department upon request.

Currently there is an $850 annual operating fee for each registered oil or gas well facility. Operating fees are reviewed annually and may be subject to change.

  • You may request to deregister a facility if it can be clearly demonstrated that the potential to emit (PTE) of the facility is less than 25 tons per year (tpy) of any regulated airborne pollutant.
  • Facilities that are not deregistered prior to March 1 are subject to the annual operating fees for that year.
  • There is no required form to submit for a deregistration request, however, when a full PTE analysis is required, the Department recommends that the Oil or Gas Well Registration form be used.
  • Submit a request to deregister a facility along with supporting information by email to: DEQ-ARMB-Admin@mt.gov.

Crushers and Screens

Some general guidance for registered crushing and screening facility operation is described below.

Need to register? Please go to the “New Facility” page, click on Registered Sources, and visit the “What do I need to do to register” banner to obtain a registration form. All nonmetallic mineral crushing and screening facilities meeting the applicability requirements of ARM 17.8.1802, including those facilities previously covered under a Montana Air Quality Permit, are required to register in accordance with the Administrative Rules of Montana (ARM) Title 17, Chapter 8, Subchapter 18 – Standards and Requirements for Sand and Gravel, Concrete, and Asphalt.

If certain changes occur at a registered nonmetallic mineral processing plant (NMMPP), the owner or operator must work with the Department to update the registration. Examples of registration updates include:

  • Owner/Operator Updates: Registrations are nontransferable. If the owner or operator of a registered NMMPP changes, the new owner or operator is responsible for ensuring that the facility is properly registered. If the new owner or operator is not already registered to operate an NMMPP under this program, the new owner or operator must register using the Air Quality Registration Notification form as described in Section 4 of the Nonmetallic Mineral Processing Plants guidance. If the new owner or operator is already registered to operate NMMPP under this program, and the new facility will be operated at one of the owner or operator’s existing locations, there is no need to submit a new Registration Notification or any form
  • Deregistration: If you will no longer operate NMMPP in Montana and wish to be removed from the program, you must fill out a Air Quality Deregistration Notification form and submit it to the Department to avoid being charged an annual fee.
  • Location Updates: For any proposed new temporary or permanent location, the owner or operator shall notify the Department using the Attachment A – Location Notice & Update form at least 15 days before beginning to operate at the location.

Initial performance tests for visible emissions. Any NMMPP that is subject to the additional federal regulations of 40 CFR 60 Subpart OOO must conduct initial emissions tests within 180 days of initial startup to demonstrate compliance with the opacity limitations. If you have already completed initial performance tests, the written report of the results of these tests must be presented to the Department upon request.

Additional tests. The Department has the authority to require an emissions performance test. All emissions performance tests must conform to the requirements of the Montana Source Test Protocol and Procedures Manual.

Registered sources must maintain records that can be produced during an inspection for demonstrating compliance with this program. The records must also be submitted to the Department upon request. Records must include:

  • The location at which the facility was operated.
  • Daily production rates and rolling 12-month total production.
  • Daily horsepower-hours of engines and rolling 12-month total horsepower hours for operations at permanent locations.

Submit a request to deregister a facility using the Air Quality Deregistration Notification form along with supporting information by email to: DEQ-ARMB-Admin@mt.gov.

If you have already completed an initial performance test, the written report of the results of the test must be presented to the Department upon request. The asphalt production rate may not exceed the average production rate during the most recent source test that demonstrated compliance. The owner or operator may retest at a higher production rate at any time.

Additional Tests. The Department has the authority to require an emissions performance test. All emissions performance tests must conform to the requirements of the Montana Source Test Protocol and Procedures Manual, which is available here.
