Which UST system components require annual inspections?

  1. Containment sumps only

  2. Hand held release detection equipment only

  3. Containment sumps and hand held release detection equipment

  4. All UST components

The correct answer is: Containment sumps and hand held release detection equipment

Annual inspections are a crucial part of maintaining the integrity and safety of Underground Storage Tank (UST) systems. The components that require these inspections are specifically the containment sumps and handheld release detection equipment. Containment sumps are designed to collect leaks and spills from the UST systems, and they serve as a primary line of defense against environmental contamination. Inspecting them annually ensures that any potential leaks are detected and addressed promptly. Handheld release detection equipment is also essential for monitoring the integrity of USTs, as it helps in detecting any fuel releases that may occur. Regular annual inspections of this equipment ensure that it functions correctly and can reliably provide accurate release detection. Thus, both containment sumps and handheld release detection equipment are mandated to undergo annual inspections for compliance and environmental protection, reinforcing the importance of routine checks to maintain operational safety and regulatory adherence in UST management.
