California ICC UST Inspector Practice Exam

What is included in the definition of an underground storage tank system?

1. The tank and all connected piping and dispensers

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

3. Only the tank itself

4. Only tanks that are totally beneath the surface of the ground

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

The definition of an underground storage tank (UST) system encompasses not just the tank itself but also other critical components associated with it. Specifically, it includes the tank, connected piping, ancillary equipment such as pumps and filters, and a containment system. This broader definition is essential for a complete understanding of UST systems because it highlights the importance of various elements in preventing environmental contamination and ensuring safe operation. By including ancillary equipment and containment systems, the definition reflects regulatory requirements aimed at minimizing leaks and spills. These additional components play a crucial role in managing potential hazards and ensuring that any leaks are contained and dealt with appropriately to protect the environment and comply with safety regulations. This comprehensive understanding is essential for inspectors and those involved in the operation and maintenance of UST systems in California and beyond.
