The goal of the Underground Storage Tank (UST) Program is to protect public health and safety, the environment, and the waters of the state from discharges and releases of hazardous substances from USTs. These hazardous substances include petroleum, used oil, waste antifreeze, and more. This goal is accomplished by conducting annual inspections, reviewing and approving submissions regarding UST installations, repairs, upgrades, and closures, overseeing UST system closure activities, and more.
