California ICC UST Inspector Practice Exam

What is a monitoring requirement that applies to all double wall piping, including suction and gravity systems?

1. All secondary containment must be equipped with a continuous monitoring system.

2. A 0.1 gph annual pipe integrity test must be conducted.

3. Positive pump shut-down and fail-safe must be installed.

4. After November 9, 2004, automatic line leak detectors shall be installed.

The correct answer is: All secondary containment must be equipped with a continuous monitoring system.

The requirement that applies to all double wall piping, including suction and gravity systems, is that all secondary containment must be equipped with a continuous monitoring system. This is essential because double wall piping systems are designed to provide an additional layer of protection against leaks and spills. The secondary containment features an outer wall that can detect any leakage from the inner wall, helping to prevent environmental contamination. Continuous monitoring systems are integral to maintaining the environmental integrity and operational safety of underground storage tanks. By having a continuous monitoring system, any potential issues such as leaks can be detected and addressed promptly, minimizing the risk of hazardous substances escaping into the environment. Other options, while they pertain to various aspects of underground storage tank regulations, do not uniformly apply to all double wall piping systems. For instance, annual tests and installation of automatic line leak detectors may be specific to certain conditions or systems rather than being a blanket requirement for all double wall setups. Therefore, the focus on continuous monitoring directly aligns with the principles of safety and environmental protection inherent in double wall piping systems.
