.04 Investigation.

A. Within 15 days of the notice of the Central Collection Unit's intention to certify his name or of the Comptroller's having intercepted his refund, a debtor has the right to request an investigation by the Central Collection Unit if the debtor disputes the validity or the amount of the debt.

B. The Central Collection Unit shall submit to the debtor a report of its findings within 15 days from the date that the request for investigation was received. The report shall include a notice of the right to request a hearing on the findings and the method of doing so in accordance with the Administrative Procedure Act.

C. If the investigation results in the reduction or elimination of the debt, the Central Collection Unit shall take corrective action as necessary, by correcting the certification, discontinuing the certification procedures, or remitting to the debtor any intercepted amounts in excess of the debt. Corrective action shall be taken within 30 days of the date on which the Central Collection Unit completes a report of its findings.
