At what line pressure must automatic line leak detectors detect leaks?

Automatic line leak detectors (ALLDs) are crucial components in monitoring underground storage tank systems, particularly for ensuring environmental safety and compliance with regulations. In New York State, it is mandated that ALLDs are capable of detecting leaks at a line pressure of 10 psi.

This threshold is important because it ensures the system is sensitive enough to identify leaks that could potentially harm the environment or result in significant financial losses for operators. Operating the detection system at or above this pressure means that even small leaks should be detected quickly, making it easier to address issues before they escalate into larger problems.

By requiring the leak detection to be effective at this specific pressure, regulatory standards are aligned with best practices in risk management and environmental protection. This level of scrutiny helps maintain the integrity of the tank systems and minimizes potential leakage impacts. Other pressures, such as 5 psi, 15 psi, and 20 psi, do not meet the established criteria set for effective leak detection in underground storage systems.
