1. The tank, all connected piping and dispensers

2. The tank, all connected piping, ancillary equipment and containment system

3. Only the tank

4. Only tanks totally beneath the surface of the ground

The correct answer is: The tank, all connected piping, ancillary equipment and containment system

An underground storage tank system is defined to encompass not just the tank itself, but a comprehensive set of components essential for its operation. This includes all connected piping, ancillary equipment, and a containment system, which collectively ensure the safe storage and handling of the substances within the tank. The inclusion of connected piping is crucial, as it facilitates the flow of contents to and from the tank, making it an integral part of the storage system. Ancillary equipment can include pumps, valves, and other devices that support the tank's function, while the containment system provides additional protection against leaks or spills, ensuring environmental safety and regulatory compliance. This definition aligns with regulatory standards, which aim to mitigate the risks associated with underground storage tanks by emphasizing the importance of these components in maintaining system integrity and safety.
