How frequently must interstitial monitors be checked when using secondary containment?

• A. Once a week
• B. Every 30 days
• C. Every 60 days
• D. Once a year

Answer: (B)

When utilizing secondary containment systems for underground storage tanks (USTs), interstitial monitoring is essential for detecting leaks and ensuring environmental safety. The regulatory guidance typically mandates that interstitial monitors be checked at least every 30 days. This frequency helps to ensure that any potential leaks in the primary tank or piping are detected promptly, minimizing the risk of environmental contamination. Conducting these checks every 30 days provides a balance between adequate oversight of the containment system and operational practicality. This regulation reflects a commitment to proactive leak detection, vital for maintaining compliance with environmental regulations and ensuring public safety. Monitoring more frequently than this might not be necessary for all situations, while monitoring less frequently could increase the risk of undetected leaks and the associated consequences.
