California ICC UST Inspector Practice Exam

Who must approve the design and construction of a secondary containment system that's not integral to primary containment?

1. State registered professional engineer

2. Nationally recognized industry code

3. Nationally recognized engineering standard

4. Local agency

The correct answer is: Local agency

The design and construction of a secondary containment system that is not integral to primary containment must be approved by a local agency. This is because local agencies are typically responsible for enforcing regulations and codes that pertain to environmental safety and protection within their jurisdictions, including the oversight of secondary containment systems for underground storage tanks (USTs). Their approval ensures that the system meets local codes, safety standards, and environmental protection requirements. While other options refer to sources of guidelines or standards (such as professional engineers or nationally recognized codes), local agencies have the authoritative power to evaluate and approve compliance with both local regulations and state mandates. They play a critical role in ensuring that containment systems are designed adequately to prevent spills or leaks that can affect public safety and the environment.
