California ICC UST Inspector Practice Exam

All of the following are true about UST systems, EXCEPT?

1. Secondary containment testing must utilize ELD every year

2. Local agencies must be notified prior to ELD tests

3. Each UST system must have a preventative maintenance program

4. ELD can involve both manual and automatic systems

The correct answer is: Secondary containment testing must utilize ELD every year

The statement that secondary containment testing must utilize Electronic Leak Detection (ELD) every year is not accurate. While secondary containment systems are critical for preventing leaks from underground storage tanks (USTs) and periodic testing is necessary to ensure their integrity, the specific requirement for annual ELD testing may not apply universally to all UST systems. Regulatory standards may specify different intervals or methods for testing secondary containment and may not mandate the exclusive use of ELD for such testing every year. Regarding the other statements, local agencies must indeed be notified prior to ELD tests to ensure compliance with regulations and proper oversight. Each UST system is also required to have a preventative maintenance program to detect and manage risks effectively, and ELD can involve both manual and automatic systems as part of the comprehensive monitoring and testing strategy for UST integrity.
