Historical NoteReturn to Top

In 1971, the State Department of Health became the Department of Health and Environmental Sciences (DHES) with the passage of Governor Anderson’s Executive Reorganization Order 9-71. The Environmental Sciences Division remained part of DHES from that date until 1990, during which time they were responsible for monitoring air quality and water quality, solid waste management, administering the Subdivision Bureau, ensuring food and consumer safety, and occupational health. In 1991, though still a part of the Department of Health and Environmental Sciences, the role of the Environmental Sciences Division was considerably expanded to include: Natural Resource Damage Assessment, a Petroleum Tank Release Compensation Board, a Superfund Section, and an Underground Storage Tanks Section. The Environmental Sciences Division became its own separate department, renamed the Department of Environmental Quality, in 1995, and was comprised of the following divisions: Director’s Office, Air Quality, Centralized Services, Energy, Environmental Remediation, Reclamation, Waste Management, and Water Quality. Currently, the Montana Department of Environmental Quality (DEQ) is comprised of seven divisions: the Director’s Office, Enforcement, Financial Services, Information Technology, Permitting and Compliance, Planning, Prevention, and Assistance, and Remediation.

The functions of the Air Resources Management Bureau were originally covered by the Air Quality Bureau under the umbrella of the Environmental Services Division within DHES. After the creation of the DEQ in 1995, the Air Quality Bureau became the Air and Waste Management Bureau, functioning under the Permitting and Compliance Division and comprised of the Air Permitting and Air Compliance offices. The Air and Waste Management Bureau became the Air Resources Management Bureau (ARMB) in the early 2000s.

The ARMB remained under the umbrella of the Permitting and Compliance Division (defunct) until sometime prior to 2024. The ARMB regulated air emissions through permitting and compliance activities. This mandate included: issuing air quality pre-construction and operating permits; inspecting and providing compliance assistance for air emission sources; issuing permits for open burning activities; and coordinating operation of the Montana Smoke Management Program with the major open burning entities. As of 2024, the Air Resources Management Bureau has been replaced with the Air Quality Bureau, which operates within the Air, Energy, and Mining Division of DEQ.

Content DescriptionReturn to Top

This collection is composed of correspondence, case files, hearing transcripts, and subject files. The correspondence series is comprised mostly of correspondence between the AQB/ARMB and the Environmental Protection Agency, and correspondence in regards to State Implementation Plans to deal with air pollution in various cities, including Anaconda, Butte, East Helena, Libby, Missoula, and Whitefish. The Case Files series is alphabetized by company, and deals primarily with permitting and compliance. The Hearings series is comprised of transcripts of hearings for air quality cases between 1977 and 2000. Hearings revolve primarily around the adoption of air quality rules. The highlights of the Subject Files series are folders dealing with the EPA’s Clean Air Act of 1990, citations and complaints for emissions violations, and air quality quarterly contract reports by county (not all counties are represented).

Processing Note

In 2024, the various collections of the Montana Department of Environmental Quality were integrated under one collection identifier, RS 494, in order to help facilitate access, reduce redundancy in the MTHS catalog, and to follow best archival practices.

Collections from Montana Department of Environmental Quality's various Divisions and Bureaus that were previously treated as separate entities are now integrated into this collection, RS 494. Rather than reprocessing over 150 linear feet of DEQ materials, MTHS staff decided to keep the past arrangement of those collections/finding aids, and provide access to them via links through the central finding aid. This decision has allowed the MTHS archival staff to maintain intellectual control over the collection, while removing the need to reprocess it. It also keeps State Agency finding aids at manageable sizes. Please read the scope and content note carefully to determine if this subgroup/sub-subgroup pertains to your research needs.
