California Designated Operator Practice Exam

If two non-conclusive SIR reports are received, what must be performed?

1. A piping tightness test and a tank integrity test

2. A local agency review of all records

3. Only a local agency audit

4. Only a tank cleaning process

The correct answer is: A piping tightness test and a tank integrity test

The requirement to conduct a piping tightness test and a tank integrity test when two non-conclusive SIR (Statistical Inventory Reconciliation) reports are received is based on the need to ensure environmental safety and regulatory compliance. Non-conclusive SIR reports indicate that there may be discrepancies in the data regarding leak detection. This uncertainty necessitates further investigations to rule out the possibility of leaks in both the piping and the tank itself. By performing a piping tightness test, operators can assess whether the piping system is capable of retaining product without leaks. Similarly, a tank integrity test is crucial for verifying that the tank has not compromised its structural integrity. This two-pronged approach serves to confirm that there is no release of harmful substances into the environment, addressing the main concern that arises from inconclusive findings. Regulatory frameworks often mandate these tests to prevent environmental contamination, which aligns with the principles of responsible operation within the context of petroleum storage and distribution. The other options do not provide the necessary actions to ascertain the integrity of the system thoroughly. A local agency review of records, a local agency audit, or a tank cleaning process may have their roles under different circumstances, but they do not directly address the immediate need for verification of system integrity indicated by the non-conclusive
