What is the maximum leak rate that must be verified by the annual test for Electronic Line Leak Detectors?

The maximum leak rate that must be verified by the annual test for Electronic Line Leak Detectors is 3 gallons per hour. This requirement is outlined in federal regulations regarding underground storage tank systems.

Maintaining this threshold is crucial as it reflects the acceptable limit for detecting leaks from underground piping associated with USTs. The 3 gallons per hour rate ensures that any leak is manageable and within the capacity for detection and response before it can lead to significant environmental contamination or hazardous situations. In practice, this level of scrutiny helps ensure ongoing compliance with safety and regulatory standards, helping to protect the environment and promote public health. Furthermore, if the leak rate exceeds this limit, it indicates a potential failure in the leak detection system or a significant leak that requires immediate inspection and response. By adhering to the 3 gallons per hour standard, operators can effectively monitor the integrity of their UST systems and minimize risks associated with leaks.
