What is the maximum leak detection rate for an automatic line leak detector to be acceptable?

The maximum leak detection rate for an automatic line leak detector to be acceptable is 3 gallons per hour. This standard ensures that if a leak occurs, the detection system can identify it in a timely manner, minimizing the risk of environmental contamination and ensuring safety. A system that detects leaks at this rate is considered sensitive enough to alert operators to potential issues without being too sensitive or prone to false alarms. This balance is critical in maintaining the integrity of underground storage tank systems, providing a reliable method for monitoring potential leaks while adhering to regulatory requirements.

Options that specify higher gallons per hour, such as 5 or 10, would not meet the regulatory standards for leak detection, as they would allow more significant leaks to go undetected for longer periods of time, increasing the risk of environmental harm. Thus, 3 gallons per hour is established as the maximum allowable detection rate to ensure effective monitoring of leak situations in compliance with industry best practices and regulations.
