California ICC UST Inspector Practice Exam

Which of the following best describes the testing requirement for turbine piping in UST systems?

1. Must be pressure tested every month

2. Must be careful monitored every hour

3. Must have primary and secondary tests within 60 days

4. Must meet automatic line leak detection specifications

The correct answer is: Must meet automatic line leak detection specifications

The requirement for turbine piping in UST (Underground Storage Tank) systems revolves around ensuring that any potential leaks are detected promptly and effectively. The specification for automatic line leak detection is essential as it provides continuous monitoring of the piping from the tank to the dispenser. This automatic leak detection system functions by monitoring the pressure within the pipes and can quickly identify discrepancies that might indicate a leak. Timely detection of leaks is critical because it helps prevent environmental contamination, regulatory violations, and financial losses due to product loss. While options mentioning pressure tests, careful monitoring, and additional tests are relevant to UST systems in some capacity, they do not encompass the ongoing and proactive leak detection necessary for turbine piping systems. Automatic line leak detection serves as a safeguard, ensuring that any leaks are picked up immediately, contributing significantly to the overall safety and compliance of the UST operations.
