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.
