California ICC UST Inspector Practice Exam

Which of the following is considered part of the release detection system?

1. Visual inspections.

2. Product inventory monitoring.

3. Intermittent sampling.

4. Annual third-party inspections.

The correct answer is: Product inventory monitoring.

Product inventory monitoring is a critical component of the release detection system because it helps ensure that the amount of fuel recorded in storage tanks matches the amount being dispensed at the pumps. This discrepancy can indicate possible leaks or releases of hazardous substances into the environment. By continuously tracking inventory levels, operators can identify unusual variations that might suggest a leak, thus enabling timely investigations and response actions to prevent environmental contamination. Regular inventory monitoring typically involves calculating the difference between the amount of product received and the amount dispensed, aiming to spot any discrepancies that could signify a leak. It is a proactive step in ensuring the integrity of underground storage tanks (USTs) and safeguarding public health and the environment.
