Retail fueling facilities with underground storage tanks from which fuel products are offered for sale to the public are required to reconcile product inventory for each tank on a monthly basis for the life of the tank system. Inventory must be verified in order to ensure there has not been a failure of leak detection equipment or a misdelivery into the system. The process for reconciling blender systems differs from how th​e inventory on a single tank is reconciled.
