(a) Designation. The Commission shall designate a custodian and one or more deputy custodians for material to be delivered pursuant to compulsory process in an investigation, a purpose of which is to determine whether any person may have violated any provision of the laws administered by the Commission. The custodian shall have the powers and duties prescribed by section 21 of the FTC Act. Deputy custodians may perform all of the duties assigned to custodians. The appropriate Bureau Directors, Deputy Directors, Associate Directors in the Bureau of Consumer Protection, Assistant Directors in the Bureau of Competition, Regional Directors or Assistant Regional Directors shall take the action required by section 21(b)(7) of the FTC Act if it is necessary to replace a custodian or deputy custodian.

(b) Copying of custodial documents. The custodian designated pursuant to section 21 of the Federal Trade Commission Act (subject to the general supervision of the Executive Director) may, from among the material submitted, select the material the copying of which is necessary or appropriate for the official use of the Commission, and shall determine, the number of copies of any such material that are to be reproduced. Copies of material in the physical possession of the custodian may be reproduced by or under the authority of an employee of the Commission designated by the custodian.

(c) Material produced pursuant to the Federal Trade Commission Act, while in the custody of the custodian, shall be for the official use of the Commission in accordance with the Act; but such material shall upon reasonable notice to the custodian be made available for examination by the person who produced such material, or his duly authorized representative, during regular office hours established for the Commission.
