How often should underground storage tanks be inspected?

Underground storage tanks (USTs) should be inspected at least once every three years to ensure they are operating safely and in compliance with environmental regulations. This frequency of inspection allows for timely detection of leaks, corrosion, and other issues that could pose environmental risks or compromise the integrity of the tank.

Regular inspections help to maintain safety standards and prevent hazardous incidents which can be caused by the failure of tank systems. The three-year interval also aligns with regulatory requirements in many jurisdictions, ensuring that UST operators remain compliant with federal and state guidelines. By adhering to this schedule, operators can also take proactive steps in mitigating potential environmental hazards, thereby protecting groundwater and surrounding ecosystems.
