When a UST operator suspects a leak, the correct course of action is to notify the appropriate authorities and investigate the situation. This proactive response is critical because leaks can lead to environmental contamination, regulatory violations, and significant financial liabilities. By alerting the relevant authorities, the operator ensures compliance with federal and state regulations, which typically mandate immediate reporting and corrective action for suspected leaks.

Investigating the suspected leak promptly allows for determining its source, scope, and potential impacts. This investigation might include monitoring for changes in product levels, pressure tests, or utilizing leak detection systems that are already in place. Taking prompt action not only protects the environment and public safety but also helps in mitigating further damage or liability.

In contrast, ignoring the symptoms and monitoring the system would increase the risk of contamination and potential fines. Waiting for a regular inspection may lead to prolonged exposure to harmful substances and does not fulfill legal obligations. Performing routine maintenance without addressing the suspected leak would similarly neglect the immediate problems and responsibilities tied to UST operations. Therefore, notifying authorities and conducting an investigation is the most responsible and required action for an operator dealing with a suspected leak.
