California ICC UST Inspector Practice Exam

Which requirement is NOT part of the vaulted tank exemption criteria?

1. All exterior surfaces of the tank can be monitored by direct viewing

2. The structure provides for secondary containment of the tank's contents

3. The owner conducts weekly inspections of the tank

4. The local agency gets approval from the Regional Board to grant the exemption

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

The correct response addresses a key aspect of the vaulted tank exemption criteria, which is that the process for granting this exemption is managed at the local level with oversight from the Regional Board. This option reflects a procedural step that is implicit but not directly stated as an exemption criterion involving physical or operational requirements of the tank itself. The other criteria focus on the physical containment capabilities and maintenance practices associated with the tank. Monitoring the exterior surfaces by direct viewing ensures that visibility is possible for regular inspections; secondary containment safeguards against leaks or spills, providing additional environmental protection; and conducting weekly inspections reflects a maintenance protocol aimed at enhancing safety and compliance. These elements are designed to ensure that any risks associated with the tank's operation are minimized. The requirement for local agency approval, while necessary for procedural compliance, does not pertain to the tank's operational characteristics or safety measures, distinguishing it from the other criteria which are more focused on physical and operational conditions.
