Underground Storage Tank Program

The Underground Storage Tank program will continue to function solely for UST and UST related tasks. The goal of the UST 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 soil and groundwater resources and can cause explosive vapors to seep into confined spaces and occupied residences.

To help prevent contamination caused by leaking tanks, tank owners and operators must comply with state rules for UST’s. The objectives of the UST program are to ensure that UST systems are properly constructed and designed, installations, repairs, and removals are conducted and inspected by qualified individuals, active USTs are properly operated and monitored for releases, and USTs are properly closed and/or removed and the sites properly assessed for contamination.
