What is the minimum leak detection rate for an automatic tank gauge?

The minimum leak detection rate for an automatic tank gauge is 0.2 gallons per hour. This specific rate is established to ensure that any potential leaks in underground storage tanks (USTs) are identified in a timely manner, reducing the risk of environmental contamination and financial liability.

Automatic tank gauges (ATGs) are equipped to continuously monitor the volume of product in the tank and can detect discrepancies that may indicate a leak. The standard of 0.2 gallons per hour allows for a balance between sensitivity and practicality, providing a reliable means of leak detection while accommodating the realities of storage tank operations.

By detecting smaller leaks promptly, operators can take necessary action before a significant release occurs, thereby aligning with environmental protection regulations and ensuring safety.
