What action must an operator take if a UST leak is detected?

When a leak is detected from an underground storage tank (UST), it is crucial for the operator to respond promptly and appropriately to mitigate potential environmental hazards and comply with regulatory requirements. Reporting the release to the appropriate regulatory agency is a critical step in addressing the leak properly. This ensures that the incident is documented and that experts or authorities can provide guidance on the necessary remediation actions.

Initiating remediation is essential to prevent further contamination of soil and groundwater, which can have serious ecological and health implications. Additionally, regulatory bodies often have specific protocols and timelines for how operators must manage leaks, including conducting assessments and remediation efforts. This proactive approach not only fulfills legal obligations but also demonstrates a commitment to environmental stewardship and public safety.

In contrast, ignoring the leak (even if perceived as small) fails to address the potential risks associated with fuel leaks, while securing the tank and conducting inspections indefinitely would not resolve the issue or protect the environment. Transferring fuel to another tank does not solve the underlying problem of the leak and could lead to further complications. Hence, prompt reporting and remediation are the most effective and responsible actions a UST operator can take when a leak is detected.
