California ICC UST Inspector Practice Exam

Which of the following is NOT part of the criteria for the vaulted tank exemption?

1. All exterior surfaces can be monitored by direct viewing

2. The structure provides secondary containment

3. The owner conducts weekly inspections and maintains a log

4. The local agency gets approval from the Regional Board

The correct answer is: The local agency gets approval from the Regional Board

The vaulted tank exemption is designed to ensure certain safety and monitoring standards are maintained for underground storage tanks (USTs). The correct answer emphasizes that local agency approval from the Regional Board is not a criteria for this exemption. Instead, the exemption focuses on the physical and operational characteristics of the tank itself and the practices in place for monitoring and maintaining the tank. The criteria for the vaulted tank exemption include aspects like the visibility of exterior surfaces for direct monitoring, ensuring that the structure surrounding the tank provides secondary containment to prevent leaks and spills, and the requirement for the owner to conduct regular inspections accompanied by detailed logs documenting these checks. These criteria are crucial in establishing a safe and compliant system that minimizes the risks of contamination and ensures proper oversight of tank operations. However, the approval from the Regional Board, while important for overall regulatory compliance, does not directly pertain to the exemption criteria itself but rather the general regulatory framework within which these tanks operate.
