What is the definition of "leak detection" in the UST context?

Leak detection in the context of Underground Storage Tanks (USTs) refers specifically to the methods and procedures in place for monitoring these tanks for any signs of fuel releases. This encompasses various techniques designed to identify leaks at the earliest possible stage, which is critical in preventing environmental contamination and ensuring compliance with regulatory requirements. Effective leak detection is vital for the safe operation of USTs, as it enables operators to take prompt action if a leak is detected.

Other options such as techniques for repairing leaks and strategies for preventing seepage are related to the overall safety and maintenance of the tank system, but they do not define what leak detection itself entails. Similarly, estimating potential leakage based on the age of the tank is not a direct method of monitoring for actual leaks, making it distinct from the core definition of leak detection. Therefore, the correct response emphasizes the proactive monitoring aspect essential for responsible UST management.
