Montana Underground Storage Tank Act

The act regulates underground storage tanks containing petroleum and other regulated substances, giving the administering state department rulemaking authority along with powers to permit tanks, conduct inspections, take samples, and require owners and operators to report leaks and maintain inventories of the substances stored. It establishes a corrective action framework covering contamination cleanup, the treatment of petroleum mixing zones, and response to conditions posing an imminent hazard, and it sets out the scope of liability for releases together with the defenses and exclusions available. Compliance is backed by administrative and civil penalties subject to appeal, injunctions, cleanup orders, and liens, with a dedicated special revenue account supporting the program.
