Underground Storage Tanks
An underground storage tank (UST) is a tank and any underground piping connected to the tank which: holds petroleum products and has at least 10 percent of its combined volume underground. Releases from USTs due to spills, overfills, or leaking tanks and piping can cause fires or explosions that threaten people's safety. Underground storage tanks also can contaminate groundwater. Half of the U.S. population uses groundwater as a drinking water source.
UST Compliance Assistance
Compliance Assistance Programs directly involve tribes in the prevention, awareness, and cleaning up of releases from USTs in Indian Country. We assist UST owners, such as gas station owners and operators, in ensuring that they are in compliance with federal regulations. If they are out of compliance then the operators and owners can be charged with violations resulting in large fines and penalties. More importantly, if the USTs are not in compliance leaks from the UST can be released into the soil and groundwater, causing contamination of our drinking water.
Underground Storage Tank Resources
An underground storage tank system (UST) is a tank and any underground piping connected to the tank that has at least 10 percent of its combined volume underground. The federal UST regulations apply only to UST systems storing either petroleum or certain hazardous substances.
When the UST program began, there were approximately 2.1 million regulated UST systems in the United States. Today there are far fewer since many substandard UST systems have been closed. For the most current statistics, see UST Performance Measures. Nearly all USTs regulated by the underground storage tank requirements contain petroleum.
