How often must overfill prevention equipment be inspected for operability?

Annually
Every 2 years
Every 3 years
Every 5 years

The correct answer is: Every 3 years

Overfill prevention equipment is a critical component of a Underground Storage Tank (UST) system as it helps to prevent the overflow of hazardous substances during the transfer process. The requirement for inspecting this equipment every 3 years for operability aligns with regulatory standards aimed at maintaining safety and environmental protection. Regular inspections ensure that the overfill prevention mechanisms, such as alarms and shut-off valves, are functioning correctly. This frequency allows for timely identification and correction of any malfunctions, reducing the risk of spills that could lead to environmental contamination. By maintaining a routine inspection schedule, operators can ensure compliance with regulations and uphold safety measures. Adhering to this 3-year inspection interval is vital for compliance with state and federal regulations, which are designed to protect public health and the environment. This practice helps foster accountability in UST operations and mitigates potential risks associated with overfilling.
