How often should Class B operators conduct checks on UST systems?

Class B operators should conduct checks on UST systems as deemed necessary per protocol to ensure the safety and compliance of the operation. This reflects a best practices approach that allows for flexibility in monitoring frequency based on the specific operational circumstances and regulatory requirements.

Yardstick methods of assessments can vary by facility; thus, maintaining a standard that allows for adjustments according to the unique needs of the UST and any contextual factors—such as previous issues, the type of fuel stored, and system design—ensures optimal management of potential risks. Regular assessments also account for any directives from local regulations or company-specific protocols that may prescribe a particular frequency based on observed conditions.

This approach contrasts with fixed schedules such as daily, weekly, or checks requiring immediate action only after a leak is suspected—options that may not adequately address the operational integrity or safety needs of the UST systems at all times. Regular, as-needed checks encompass more vigilant risk management and recognition of changing conditions within the planning and operational oversight of UST systems.
