Automatic line leak detectors must be capable of detecting a release of how many gallons per hour at 10 PSI?

Automatic line leak detectors are critical components of underground storage tank systems, as they help ensure the safety and integrity of fuel delivery systems by detecting potential leaks. The requirement for these detectors to identify smaller gallons per hour releases is designed to minimize environmental risks and ensure compliance with regulations.

The correct choice indicates that automatic line leak detectors must be capable of detecting a release of 3 gallons per hour at 10 PSI. This standard is established based on industry regulations that aim to protect groundwater and soil from contamination by petroleum products. The resolution at this level allows for early detection of leaks, which is crucial in preventing significant product loss and potential environmental harm.

Detecting leaks as small as 3 gallons per hour ensures that tank operators can address issues quickly, reducing the likelihood of extensive damages, costly clean-ups, and complications from regulatory violations. This level of sensitivity strikes a balance between practicality for operators and stringent safety requirements for environmental protection.
