California Designated Operator Practice Exam

Which method requires manual inventory reconciliation in conjunction with tank integrity testing?

1. A. Automatic tank gauge testing

2. B. Statistical inventory reconciliation

3. C. Manual inventory reconciliation

4. D. Line leak detection

The correct answer is: C. Manual inventory reconciliation

Manual inventory reconciliation is a method that involves physically counting the amount of fuel in the tanks at regular intervals and comparing that with theoretical inventory records, which may include data from deliveries and sales. This method relies heavily on accurate manual measurements and record-keeping. When conducting manual inventory reconciliation, operators must also implement tank integrity testing to ensure there are no leaks or discrepancies due to tank failures. This combination ensures that any losses can be detected, and the integrity of the tanks can be verified. In contrast, automatic tank gauge testing uses electronic sensors to continuously monitor the levels of fuel in the tanks, requiring less manual input. Statistical inventory reconciliation employs statistical analysis to detect discrepancies, reducing the dependence on manual methods. Line leak detection focuses specifically on identifying leaks in the piping systems and does not directly relate to inventory management. These methods either reduce or replace the need for manual inventory reconciliation, which makes it clear why manual reconciliation stands out as the correct answer in this context.
