An Underground Storage Tank (UST) is a tank and any underground piping connected to the tank that has at least 10 percent of its combined volume underground. UST's used to store petroleum are regulated in the United States to prevent release of petroleum and contaminatoin of groundwater.
From the EPA website: Many USTs installed made before 1980 consisted of bare steel pipes, which corrode over time, and may eventually result in leakage. Faulty installation and inadequate handling may also cause leaks.
