California UST System Operator Practice Test

Who is primarily responsible for spill and overfill controls during a delivery to a UST system?

1. The delivery driver

2. The UST system owner

3. The fuel supplier

4. The regulatory agency

The correct answer is: The delivery driver

The delivery driver holds the primary responsibility for spill and overfill controls during a delivery to a UST (Underground Storage Tank) system. This is because the driver is directly engaged in the operation of transferring fuel and must actively monitor the process to ensure that the tank does not overflow. During this operation, the driver is responsible for utilizing equipment such as automatic shut-off systems and conducting visual checks throughout the delivery to prevent any unintentional releases of fuel. Additionally, the driver usually receives specific training related to spill prevention and overfill controls, which empowers them to act decisively in preventing incidents. This ensures that they are well-versed in the appropriate protocols and safety measures necessary when engaging with the UST system. While other parties, such as the UST system owner, fuel supplier, and regulatory agencies, have roles concerning maintenance, compliance, and oversight, the hands-on responsibility during the actual delivery falls squarely on the driver.
