Underground Storage Tank Program | Notice of Proposed Rule Amendment| Comment Period Closes August 7, 2026

  • July 10 2026

Rulemaking Background: The Department of Environmental Quality (DEQ) is proposing several amendments to Title 17, chapter 56 of the Administrative Rules of Montana, pertaining to Title 75, chapter 11, Underground Storage Tanks, Montana Code Annotated.

The Montana DEQ, at the direction of the Governor’s Office, has prioritized fixing the "readability" found in some Administrative Rules. Our review of the rules for the Underground Storage Tank Program identified twenty-three rules that represented material that should be made easier to read by reducing the grade level at which the rules are written; or, alternatively, removed.
