Processing Information
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.
