The Automatic Tank Gauge (ATG) shall test the tank at a leak rate of at least what?

0.1 gph
0.2 gph
0.5 gph
1.0 gph

The correct answer is: 0.2 gph

The correct answer, 0.2 gph, is significant because this threshold is established to ensure the reliability and effectiveness of the leak detection for underground storage tanks (USTs). Testing at a leak rate of 0.2 gallons per hour allows for the detection of smaller leaks which might otherwise go unnoticed. This rate provides a balance between sensitivity and operational feasibility, ensuring that potential leaks are identified while not overwhelming the system with excessive false alarms. This standard is part of compliance with federal and state environmental regulations that aim to prevent environmental contamination. By requiring the ATG to test at this specific rate, it not only aids in the early detection of leaks but also supports the protection of groundwater resources from potential pollutants stored in USTs.
