California ICC UST Inspector Practice Exam

According to California Law, when must a one-time ELD test be conducted for UST systems installed after July 1, 2003?

1. If located within one mile of a public drinking water well

2. If located within 1000 feet of a public drinking water well

3. Unless equipped with secondary containment

4. In all cases

The correct answer is: In all cases

A one-time ELD (Electronic Leak Detection) test is mandated for UST (Underground Storage Tank) systems installed after July 1, 2003, in order to establish that the system is functioning correctly and preventing leaks into the environment. This requirement emphasizes the importance of leak detection in safeguarding both public health and the environment from potential contamination, particularly from hazardous substances stored in USTs. Conducting such tests in all cases aligns with the regulatory intent to ensure comprehensive monitoring of UST systems, regardless of their proximity to public drinking water sources or existing containment measures. This proactive approach helps to identify potential failures early and mitigate risks associated with UST operation, contributing to the protection of groundwater and public water supplies. Thus, the requirement for a one-time ELD test in all circumstances reflects a commitment to rigorous oversight and compliance in the management of USTs throughout California.
