What must an operator do if a reportable release is identified?

When a reportable release is identified, the operator is required to take immediate action by notifying the appropriate authorities within a two-hour timeframe. This requirement is in place to ensure that any potential environmental contamination is addressed quickly to minimize harm and ensure compliance with environmental regulations. Rapid reporting enables swift mobilization of response teams, assessment of the situation, and initiation of necessary remediation efforts.

Cleaning the site may be part of the response actions, but it should be conducted after the notification process is complete and in accordance with established procedures. This helps in documenting the incident accurately and ensures that all regulatory requirements are met regarding incident response and reporting. The two-hour notification rule serves as a critical aspect of compliance and safety in managing underground storage tank (UST) operations.
