prevent a problem in the future. It will also ensure that the fill and vent pipes are properly connected and correctly identified. In those cases where a new tank has been installed for an existing customer, the tank inspection should include procedures to ensure that inactive fill and vent pipes have been removed. The inspections are different for aboveground tanks and buried tanks. 2.) Routine inspections NORA recommends that additional tank inspections be conducted as an integral part of preventative maintenance tune-ups. While not as comprehensive as the initial inspection, routine inspections are equally important. Routine inspections can detect problems that occur after the tank has passed the initial Chapter 3 Oil Tanks and Piping 3-12 Oil Tanks and Piping inspection. For example, the tank gauge may have become defective, a tank leg may start to corrode, or another problem may have arisen long after the tank was initially approved for delivery. In many situations, routine inspections detect minor problems that have recently started and that can be easily corrected before they cause a problem. 3.) Brief, pre-delivery inspection NORA recommends a “no-whistle-no fill policy.” Oil delivery personnel should perform a brief visual inspection before and after each delivery. While this inspection normally isn’t documented, it’s important that fuel drivers understand the need to verify addresses and check tanks for obvious defects before and after delivery.
