What is the operational requirement for an automatic line leak detector?

Test the foot valve annually.
Exercise the "automatic reset" monthly.
Check the interstitial space weekly for liquid.
Test the automatic line leak detector's operation certified every 12 months.

The correct answer is: Test the automatic line leak detector's operation certified every 12 months.

An automatic line leak detector (ALLD) is an essential component in monitoring underground storage tanks to ensure that leaks are detected promptly. The operational requirement that it must be tested and certified every 12 months is crucial for maintaining the integrity and safety of the storage system. This annual testing ensures that the device is functioning correctly and can accurately detect small leaks in the piping system that could lead to environmental hazards. Regular certification not only guarantees compliance with regulatory standards but also helps in maintaining public safety and environmental protection by providing a reliable means of early leak detection. This is especially important considering the potential for contamination of soil and groundwater which could arise from undetected leaks. The other options do address maintenance practices but do not meet the specific operational requirement for automatic line leak detectors as mandated in regulatory frameworks, which focus on consistent and reliable performance verification through annual testing.
