Annual Underground Storage Tank (UST) System Inspection Checklist

While UST Systems require regular inspection and maintenance, an annual inspection that is more in depth and detailed is important for ensuring the safe operation of a UST System. This Annual UST System Inspection Checklist provides an easy to use form that a UST Operator or owner can use to evaluate the state of a UST. The form checks dispenser sumps, product shear valves, automatic tank gauges, interstitial monitoring, inventory control, line leak detectors, soil vapor monitoring, groundwater monitoring and more. The checklist also has coverage for the tank area which includes a containment sump, overfill protection, and more. An owner of UST should have a UST program in place that includes a checklist such as this one, along with corrective actions that can be undertaken. Use of this annual checklist and any corrective actions should be covered in operator training. Leak detection is important to ensure hazardous materials don't leak into the environment - for example, fuel storage tank underground that has corrosion on the pipes or the tank itself is subject to leaking, and contaminating water sources.
