What must happen if double-walled spill buckets are no longer monitored for at least 30 days?

They must be replaced
They must be tested for liquid tightness within 1 year
They do not need any action
They must be monitored weekly

The correct answer is: They must be tested for liquid tightness within 1 year

If double-walled spill buckets are no longer monitored for at least 30 days, it is imperative that they be tested for liquid tightness within one year. This requirement ensures that any potential leaks or failures in the containment system are identified and addressed promptly. The rationale behind this stipulation is centered on maintaining environmental protection and safeguarding public health by ensuring that no hazardous substances can escape into the surrounding environment. Regular monitoring is crucial because it provides continuous assurance that the spill buckets are functioning as intended. If monitoring ceases, there may be undetected issues that could lead to environmental contamination. By requiring the liquid tightness testing within a specified timeframe, regulatory agencies aim to mitigate these risks and ensure compliance with safety standards, ultimately maintaining the integrity of the underground storage tank system.
