California ICC UST Inspector Practice Exam

Can a previously lined tank be lined again?

1. No

2. Yes, if approved by local agency

3. Yes, if approved by SWRCB

4. Yes, if approved by tank installation certified persons

The correct answer is: No

In evaluating whether a previously lined tank can be lined again, it is important to consider industry standards and regulations regarding tank integrity and maintenance. The correct approach recognizes that, typically, once a tank has undergone a lining process, it is generally not advisable or allowed to re-line it without specific authorizations or evaluations. Regulatory bodies often require comprehensive assessments to determine the condition of the tank and whether it can safely accommodate another lining. The integrity of the first lining must be thoroughly evaluated, and if re-lining were permissible, it would need to be based on rigorous standards for safety, environmental protection, and operational reliability. Moreover, local regulations and agencies may offer guidelines on how to manage lined tanks or conditions under which additional lining might be considered, but the prevailing standard often leans towards not allowing further linings without significant justification, expert assessments, and approvals. Therefore, the idea that lining a tank again without further evaluation or authority is typically rejected aligns with regulatory expectations.
