UST systems must be monitored for releases at least once every _____.

• A. 7 days
• B. 15 days
• C. 30 days
• D. 60 days

Answer: (C)

The main idea is timely release detection: you need regular checks to catch leaks before they cause significant environmental damage. UST systems must be monitored for releases at least monthly, every thirty days. This monthly cadence is the minimum that regulatory standards expect, because detecting leaks promptly minimizes soil and groundwater contamination and keeps cleanup costs and penalties manageable. While some sites may monitor more often, the required minimum is monthly; intervals like sixty days would risk undetected leaks, while shorter intervals are simply more frequent than the minimum.
