California ICC UST Inspector Practice Exam

For monitoring single wall suction piping, which of the following is not a requirement?

1. Daily monitoring as per 23 CCR, Chapter 16, Appendix II

2. Written records of the daily inspection must be maintained at the facility site.

3. A line leak detector capable of a 3.0-gph test must be installed.

4. Must be tested at least every three years.

The correct answer is: A line leak detector capable of a 3.0-gph test must be installed.

The requirement for monitoring single wall suction piping is detailed to ensure environmental protection and regulatory compliance. Daily monitoring, as outlined in 23 CCR, Chapter 16, Appendix II, is essential for detecting leaks as soon as they occur. Similarly, maintaining written records of daily inspections at the facility ensures that there is accountability and traceability of the monitoring process, establishing a predictable management routine for potential issues. Testing every three years is also a critical aspect of maintaining the integrity and safety of the suction piping system. Regular testing helps confirm that the system continues to operate as intended and identifies any potential weaknesses that might lead to leaks. On the other hand, while a line leak detector is important, the specific requirement for a 3.0-gph test applies primarily to double-walled systems and storage tanks where a higher standard for leak detection is mandated. For single wall suction piping, this requirement is not as stringent, making the installation of this capability not universally obligatory.
