California ICC UST Inspector Practice Exam

What is required for tanks before installation at a UST facility?

1. Visual inspection by the owner

2. Testing for tightness

3. Certification from a local agency

4. Approval from an independent testing organization

The correct answer is: Testing for tightness

Testing for tightness is a critical requirement for tanks before installation at a UST (Underground Storage Tank) facility. This testing ensures that the tank does not leak, which is essential for preventing environmental contamination and protecting groundwater resources. Conducting a tightness test verifies the integrity of the tank and its ability to safely store the hazardous materials intended for it. This requirement is part of the broader regulatory framework aiming to minimize risks associated with UST operations and ensure compliance with environmental protection standards. Without establishing that a tank is tight and free from leaks before installation, there is a significant risk of future release into the environment, which could lead to costly cleanup efforts and legal liabilities. While pre-installation visual inspections, certifications, and approvals may also be steps in the process of tank management and installation, the emphasis on tightness testing highlights its importance in ensuring tank safety and compliance from the very beginning of its operational life.
