45 CFR § 31.1 - Purpose and scope.
(b) Authority. These standards and procedures are authorized under the tax refund offset provision of the Deficit Reduction Act of 1984, as amended by the Debt Collection Improvement Act of 1996, codified at 31 U.S.C. 3720A, and the implementing regulations issued by the Department of the Treasury at 31 CFR 285.2.
(1) This part applies to all Departmental Operating Divisions and Regional Offices that administer a program that gives rise to a past-due non-tax debt owed to the United States, and to all officers or employees of the Department authorized to collect such debt. This part does not apply to any debt or claim owed to the Department of Health and Human Services by another Federal agency.
(2) Nothing in this part precludes the Department from pursuing other debt collection procedures, including administrative wage garnishment under part 32 of this title, to collect a debt that has been submitted to the Department of the Treasury under this part. The Department may use such debt collection procedures separately or in conjunction with the offset collection procedures of this part.
