How often must a secondary containment interstitial monitor be checked?

The requirement for checking a secondary containment interstitial monitor monthly aligns with regulatory standards pertaining to the monitoring of underground storage tanks (USTs). This regular monitoring is crucial for detecting potential leaks or failures in secondary containment systems, ensuring that any contamination risks to the environment are minimized. Monthly checks allow for timely detection of issues, which can prevent larger environmental hazards and protect public health.

In addition, maintaining a consistent schedule for these checks helps operators remain compliant with federal and state regulations, which are designed to enforce safety and reliability in UST systems. The emphasis on monthly monitoring reflects the need for vigilance in managing potential risks associated with hazardous substances stored in underground tanks.
