The rules in this part apply to the hearing provided by section 5 of the Debt Collection Act of 1982, as amended, 5 U.S.C. 5514, challenging the Postal Service's determination of the existence or amount of an employee debt to the Postal Service, or of the terms of the employee's debt repayment schedule. In addition, these rules apply to a hearing under section 5 of the Debt Collection Act when an Administrative Law Judge or an Administrative Judge in the Judicial Officer Department is designated as the Hearing Official for a creditor Federal agency other than the Postal Service pursuant to an agreement between the Postal Service and that agency. In such cases, all references to Postal Service within these rules shall be construed to refer to the creditor Federal agency involved.
