California ICC UST Service Technician Practice Exam

Automatic Line Leak Detection systems are required to detect leaks from what component?

1. Dispensing pumps

2. Storage tanks

3. Product piping

4. All of the above

The correct answer is: All of the above

Automatic Line Leak Detection (ALLD) systems are integral to maintaining safety and environmental integrity in the operation of underground storage tank (UST) systems. These systems are specifically designed to identify and prevent leaks that can lead to contamination and other hazards associated with fuel management. The requirement for ALLD systems to detect leaks encompasses multiple components of the UST system. They are essential for monitoring not just the storage tanks themselves but also the product piping that transports fuel from the tanks to the dispensing pumps. By covering all these components, ALLD systems ensure that any potential leaks are identified promptly, regardless of where they originate within the system. Thus, the necessity for ALLD to monitor dispensing pumps, storage tanks, and product piping collectively highlights the comprehensive nature of spill prevention strategies mandated by regulatory standards. This holistic approach ensures the safety of the environment and the community by addressing potential leak sources at every point in the fuel delivery system.
