What is the purpose of an automatic tank gauge (ATG) in a UST system?
The ATG monitors fuel levels and detects leaks within the tank using electronic sensors.
What function does the spill bucket serve in a UST system?
Spill buckets catch drips and spills during fuel deliveries to protect the environment.
Which part of a UST system is used to prevent fuel from being released into the environment?
The overfill prevention device ensures fuel does not exceed tank capacity during deliveries.
What is the main role of the tank vent in an underground storage system?
Tank vents release pressure and prevent vapor buildup within the tank.
What is the typical material used for modern USTs to prevent corrosion?
Fiberglass-reinforced plastic and double-walled steel are corrosion-resistant materials used in new tanks.
Which component connects the underground tank to the dispensing unit?
Piping systems transport fuel between the UST and dispensers at the surface.

Why is a leak detection system required in every UST?
Leak detection systems help identify fuel loss and prevent environmental contamination.
How does a sump help maintain system safety?
Sumps collect fuel leaks or spills around critical connection points for detection and containment.
Which sensor is often installed in sumps to alert of fuel leaks?
Interstitial sensors provide real-time detection of fuel leaks in containment areas like sumps.
