50 CFR § 25.45 - Appeals procedure.
(a) Who may appeal. Any person who is adversely affected by a refuge manager's decision or order relating to the person's permit granted by the Service, or application for permit, within the National Wildlife Refuge System. This section does not apply to permits or applications for rights-of-way. See § 29.22 for the hearing and appeals procedure on rights-of-way.
(b) Preliminary procedure. Prior to making any adverse decision or order on a permit or application for permit, the refuge manager shall notify the permittee or applicant orally or in writing of the proposed action and its effective date. The permittee or applicant shall have twenty (20) days after notification in which to present to the refuge manager, orally or in writing, a statement in opposition to the proposed action or date. The permittee or applicant shall be notified in writing within twenty (20) days after receipt of the statement in opposition, of the refuge manager's final decision or order.
(c) Appeals, how taken. If the refuge manager still intends to proceed with the proposed action, the permittee or applicant shall have thirty (30) days from the postmarked date of the refuge manager's final decision or order in which to file a written appeal to the appropriate area manager. The appellant (permittee or applicant) shall be notified in writing within thirty (30) days from the postmarked date of the appeal of the area manager's decision. The appellant shall have (30) days from the postmarked date of the area manager's decision to further appeal in writing to the appropriate regional director.
(d) Decision of regional director. The regional director's decision shall be final and issued in writing to the appellant within thirty (30) days from the postmarked date of the appeal.
(e) Oral presentation. The appellant shall be provided an opportunity for oral presentation before the area manager or the regional director within the respective thirty (30) day appeal periods.
(f) Addresses. The addresses of the appropriate officials to whom appeals may be taken shall be furnished in each decision or order.
(g) Suspension pending appeal. Compliance with any decision or order of a refuge manager shall not be suspended by reason of an appeal having been taken unless such suspension is authorized in writing by the area manager or regional director (depending upon the official before whom the appeal is pending), and then only upon a determination by these officials that such suspension will not be detrimental to the interests of the United States or upon submission and acceptance of a bond deemed adequate to indemnify the United States from loss or damage.
