California ICC UST Inspector Practice Exam

Which condition does NOT need to be recorded by the UST owner or operator?

1. Any unauthorized release under investigation

2. Discovery of released hazardous substances at the site

3. Monitoring results indicating a release may have occurred

4. A release from a dispenser hose caused by vehicle overfill

The correct answer is: A release from a dispenser hose caused by vehicle overfill

The condition that does not need to be recorded by the UST (Underground Storage Tank) owner or operator is related to the specific situation of a release from a dispenser hose caused by vehicle overfill. This scenario is typically considered a minor incident or operational error rather than an environmental release requiring formal documentation. In contrast, options such as unauthorized releases under investigation, the discovery of released hazardous substances, and monitoring results indicating a potential release are significant because they pose environmental hazards and regulatory implications. These situations require immediate attention and must be formally recorded to ensure compliance with environmental regulations, as they could lead to contamination of soil and groundwater, posing risks to human health and the environment. Therefore, the act of overfilling a vehicle at a dispenser hose, while it may need to be addressed operationally, generally does not escalate to the level of regulatory documentation that the other conditions entail. This distinction underscores the importance of recognizing the various types of incidents involving underground storage tanks and their respective reporting requirements.
