California ICC UST Inspector Practice Exam

What does a UST system include?

1. Tank only

2. Piping only

3. Tank, associated piping and ancillary equipment

4. Tank, piping, dispensing units, and nozzles

The correct answer is: Tank, associated piping and ancillary equipment

A UST (Underground Storage Tank) system encompasses more than just the tank or the piping alone; it is a comprehensive assembly designed to store regulated substances safely underground. The correct option highlights that a UST system includes the tank itself, associated piping, and ancillary equipment, which is vital for its operation and functionality. The tank is primarily where the regulated substance is stored. The associated piping connects the tank to various dispensing units or other systems, allowing for the transfer of materials in and out of the tank. Ancillary equipment includes components such as pumps, leak detection systems, and spill containment features, all of which contribute to the overall integrity and safety of the UST system. These elements work together to prevent leaks, ensure proper dispensing, and support environmental protection measures. Understanding the full scope of what constitutes a UST system is crucial for compliance with safety regulations and environmental standards, making it essential for inspectors and regulatory professionals in the field.
