Overpayments of less than $30.01 result in a systems-posted uncollectible determination,
            and no overpayment notice is sent.
         
         Waive recovery when a person liable for an overpayment of $500 or less requests waiver
            alleging without fault, if there is no evidence of fault on the part of the liable
            person apparent on the face of the waiver request. If there is evidence apparent on
            the face of the waiver request that the liable person may be at fault, continue with
            full waiver development.
