Underground Storage Tanks
The goal of the Montana Underground Storage Tank (UST) Leak Prevention Program is to protect human health and the environment by preventing releases of petroleum and hazardous substances from UST systems. The release of these regulated products into the environment threatens groundwater resources and can cause explosive vapors to seep into confined spaces and occupied dwellings.
The objectives of the UST Leak Prevention Program are to ensure that:
- UST systems are properly constructed and designed using recognized industry standards;
- installations, repairs and removals are conducted and inspected by qualified, trained and licensed individuals;
- active USTs are properly operated and monitored for releases;
- upon closure, USTs are properly decommissioned and sites assessed for contamination.
EPA State Program Approval The Montana UST Leak Prevention Program is authorized by the Environmental Protection Agency (EPA) to operate in lieu of an EPA administered federal program.
