California ICC UST Inspector Practice Exam

What requirement applies to all types of double wall piping?

1. Secondary containment must have a continuous monitoring system

2. Automatic line leak detectors are mandatory after November 2004

3. A 0.1 gph annual pipe integrity test is needed

4. Positive pump shut-down must be installed on leak detectors

The correct answer is: Secondary containment must have a continuous monitoring system

The requirement for all types of double wall piping is that secondary containment must have a continuous monitoring system. This is critical because double wall piping is designed to provide an additional layer of environmental protection by containing any leaks that may occur in the inner pipe. Continuous monitoring systems help ensure that any leaks are detected promptly, allowing for immediate action to prevent contamination of the surrounding environment. This is especially important in fueling operations where hazardous substances are involved, as timely detection can significantly reduce potential harm and liability. The requirement for a continuous monitoring system is particularly vital as it aligns with safety regulations which aim to prevent environmental damage and promote public safety. While other options may pertain to specific operational requirements or regulations, they do not universally apply to all double wall piping systems in the same manner as the requirement for continuous monitoring.
