California Designated Operator Practice Exam

How often must a tank integrity test be conducted according to the annual requirements?

1. Every month

2. Every six months

3. Once every two years

4. Once a year

The correct answer is: Once every two years

The correct frequency for conducting a tank integrity test according to the annual requirements is once every two years. This interval is established to ensure that tanks, particularly those that hold hazardous materials, are regularly assessed for leaks, structural integrity, and overall compliance with safety regulations. Conducting the test every two years balances the need for safety with practical operational considerations, allowing enough time between tests to gather useful data while minimizing disruptions to routine operations. This approach also mitigates the risk of environmental contamination and ensures that any issues can be addressed in a timely manner without imposing unnecessary financial burdens on operators who must manage ongoing testing. In contrast, conducting tests every month or every six months would be overly rigorous and impractical for most operators, while testing once a year may not provide sufficient oversight for early detection of potential integrity issues.
