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

1 gallon per hour
2 gallons per hour
3 gallons per hour
4 gallons per hour

The correct answer is: 3 gallons per hour

Automatic line leak detectors (ALLD) are a critical component of the underground storage tank (UST) system, designed to enhance environmental protection by identifying leaks in the petroleum distribution lines. These detectors are required to be sensitive enough to detect the smallest potential leak before it can cause significant environmental harm or financial loss. The standard for these leak detection systems mandates that they should be capable of identifying a leak rate of at least 3 gallons per hour. This threshold is established to ensure that any leakage, which could have serious implications for soil and groundwater contamination, is promptly detected and addressed. By setting this standard, regulators aim to minimize the risk of environmental damage caused by leaks in UST systems. In contrast, the other options reflect lower rates, which do not meet the current safety standards for automatic line leak detection. Thus, the correct answer reflects the minimum leak detection capability that ensures compliance with regulations and protects public health and the environment.
