California ICC UST Inspector Practice Exam

When must the capacity of an underground storage tank be evaluated?

1. Bi-annually during service maintenance

2. After tank installation every three years

3. Every year alongside annual inspections

4. Upon installation and every five years thereafter

The correct answer is: Every year alongside annual inspections

The capacity of an underground storage tank (UST) must be evaluated every year alongside annual inspections. This regular evaluation helps ensure that the tank operates within its designed capacity limits and aids in identifying any potential issues that could lead to leaks or environmental contamination. Annual inspections typically cover various aspects of the tank, including its structural integrity and compliance with relevant regulations. Conducting the capacity evaluation annually also aligns with best practices in tank management. It allows for consistent monitoring and timely responses to any discrepancies that may arise, enhancing overall safety and environmental protection measures. By keeping such evaluations frequent, operators can maintain a proactive approach in managing the risks associated with USTs. In contrast, the other options propose intervals that do not adequately support the ongoing monitoring needed to safeguard the environment and public health. Bi-annual evaluations may not catch issues that arise in between those periods, while evaluations after installation or on a five-year cycle do not provide enough frequency to ensure compliance and safety.
