40 C.F.R. §§ 2.403–2.406

A request for testimony by an EPA employee under § 2.402(b) must be in writing and must state the nature of the requested testimony and the reasons why the testimony would be in the interests of EPA. Such requests are immediately sent to the General Counsel or his designee (or, in the case of employees in the Office of Inspector General, the Inspector General or his designee) with the recommendations of the employee's supervisors. The General Counsel or his designee, in consultation with the appropriate Assistant Administrator, Regional Administrator, or Staff Office Director (or, in the case of employees in the Office of Inspector General, the Inspector General or his designee), determines whether compliance with the request would clearly be in the interests of EPA and responds as soon as practicable.

Subpoenas duces tecum for documents or other materials are treated the same as subpoenas for testimony. Unless the General Counsel or his designee, in consultation with the appropriate Assistant Administrator, Regional Administrator or Staff Office Director (or, as to employees in the Office of Inspector General, the Inspector General) determines that compliance with the subpoena is clearly in the interests of EPA, the employee must appear at the stated time and place (unless advised by the General Counsel or his designee that the subpoena was not validly issued or served or that the subpoena has been withdrawn) and respectfully refuse to produce the subpoenaed materials. However, where a subpoena duces tecum is essentially a written request for documents, the requested documents will be provided or denied in accordance with subparts A and B of this part where approval to respond to the subpoena has not been granted.

Requests for authenticated copies of EPA documents for purposes of admissibility under 28 U.S.C. 1733 and Rule 44 of the Federal Rules of Civil Procedure will be granted for documents which would otherwise be released pursuant to subpart A. For purposes of Rule 44 the person having legal custody of the record is the cognizant Assistant Administrator, Regional Administrator, Staff Office Director or Office Director or his designee. The advice of the Office of General Counsel should be obtained concerning the proper form of authentication.
