California ICC UST Inspector Practice Exam

Which of the following must be approved by an independent testing organization for primary containment design?

1. Industry codes

2. Local agency standards developed by the State Water Resources Control Board

3. Voluntary consensus standards

4. Engineering standards

The correct answer is: Local agency standards developed by the State Water Resources Control Board

The requirement for primary containment design to be approved by an independent testing organization is primarily tied to local agency standards developed by the State Water Resources Control Board. These standards ensure that the design of containment systems used for underground storage tanks (USTs) meets specific safety and environmental protection criteria. The State Water Resources Control Board oversees these standards to prevent leaks and ensure the integrity of UST systems, which is crucial for safeguarding water resources. Approval by independent testing organizations provides an assurance that the designs comply with these established regulations and are subject to rigorous evaluation, thus enhancing public health and environmental safety. Other options may involve various forms of compliance standards and design codes, but they may not specifically require independent testing organization approval for primary containment design as stipulated by local agency standards.
