What should be included in the monitoring system certification form?

The monitoring system certification form should indeed include every UST (Underground Storage Tank) and dispenser at the facility. This comprehensiveness is essential for compliance with regulatory standards, as it ensures that all components of the fuel storage system are accounted for in the certification process. It provides a complete picture of the facility's operations and the environmental protections in place, helping to verify that all tanks and dispensers are monitored properly to prevent leaks and ensure safety. By including all units, the form facilitates an accurate assessment of the entire system's performance and compliance status, ultimately contributing to better environmental protection and risk management strategies.

In contrast, focusing solely on UST capacity, historical maintenance records, or just active installations would provide an incomplete overview of the monitoring required and could lead to gaps in compliance or oversight.
