California ICC UST Inspector Practice Exam

What must pressurized piping systems have installed by November 9, 2004?

1. Double-walled spill buckets

2. Hydrostatically lined UDCs

3. Line leak detectors

4. ATGs

The correct answer is: Line leak detectors

Pressurized piping systems are required to have line leak detectors installed to ensure that any leaks in the system can be identified quickly and accurately. This requirement is critical for maintaining the integrity of underground storage tank systems and preventing environmental contamination. Line leak detectors monitor the pressure within the piping system and can detect discrepancies that may indicate a leak, thereby allowing for timely intervention and repair. Ensuring that these systems are equipped with line leak detectors enhances safety and compliance with regulations, as it addresses the significant risks associated with leaking fuel or hazardous substances. This is crucial for protecting both public health and the environment. The other options, while also relevant to UST systems, do not specifically pertain to the requirement for pressurized piping established by the regulations that were in place by November 9, 2004.
