What is the leak detection requirement for automatic line leak detectors?

The leak detection requirement for automatic line leak detectors is set at 3 gallons per hour. This specification is crucial for ensuring the integrity of underground storage tanks (USTs) and minimizing environmental risks associated with leaks. Automatic line leak detectors are designed to continuously monitor the piping systems of USTs for any signs of fuel leakage and are sensitive enough to detect small leaks that can lead to significant environmental contamination over time.

Setting the threshold at 3 gallons per hour allows operators to identify leaks that can occur under operational conditions without resulting in false alarms. This standard serves as a critical component of UST regulations, ensuring that operators can effectively manage risks associated with fuel storage and distribution. Adhering to this requirement not only helps in regulatory compliance but also protects public health and the environment from the adverse effects of releasing petroleum products into the ground or groundwater.
