What is an Underground Storage Tank (UST)?
An underground storage tank (UST) is a tank and any connected underground piping that has at least 10 percent of its combined volume underground. Federal regulations require owners/operators of USTs to have proper corrosion protection, spill and overfill protection, a leak detection system, and financial assurance for liability.
If the USTs are not in compliance or upgraded, the tanks may leak into the ground water, surface water or surrounding soil causing harm to the public health and safety of the people and the environment.
- Identify tank owners and provide technical assistance and trainings for owners and operators.
- Assist and support US EPA on compliance inspections and other UST activities.
