High Quality Content by WIKIPEDIA articles An Underground Storage Tank (UST), in United States environmental law, is a tank and any underground piping connected to the tank that has at least 10 percent of its combined volume underground. USTs, used to store petroleum, are regulated in the United States to prevent release of petroleum and contamination of groundwater, they are used throughout North America at automobile filling stations and many have leaked, allowing petroleum to contaminate the soil and groundwater. Many USTs installed 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. In 1984, in the United States, the Congress developed laws to minimize and prevent environmental damage, by charging owners with the task of verifying, maintaining and, if necessary, cleaning up sites damaged by petroleum contamination.
