What steps should be taken if a UST system fails a leak detection test?

When a UST (Underground Storage Tank) system fails a leak detection test, it is critical to investigate the cause of the failure. This involves conducting a thorough assessment to determine if there is an actual leak and identifying the source of the issue. It is crucial to address any potential environmental risks and ensure that the tank and any associated systems are functioning correctly.

Once the cause is identified, necessary repairs must be made to rectify the issue, which could involve fixing faulty equipment, sealing leaks, or any other required maintenance actions. After the repairs, the system must undergo retesting to confirm that the leak detection system is now functioning properly and that the tank is compliant with safety regulations. This process protects both the environment and public health.

Continuing regular operations without addressing a failure poses significant risks of environmental contamination and regulatory violations. Notifying employees and waiting for the next inspection does not adequately address the immediate concern of a possible leak. Similarly, emptying the tank and discarding it is generally unnecessary unless extensive damage is found, and it does not contribute to resolving the issue effectively. Thus, the correct response involves a proactive approach of investigating, repairing, and retesting the system.
