(a) Requests for amendments to active permits (e.g., a change in study design or research personnel) must conform to the regulations in this part. All information deemed necessary by the NHHC to make an objective evaluation of the amendment must be included as well as reference to the original application. Requests for amendments must be sent to the Deputy Director, Naval History and Heritage Command, 805 Kidder Breese St. SE., Washington Navy Yard, Washington DC 20374-5060. A pending amendment request does not guarantee approval and proposed activities cannot commence until approval is granted. All requests for permit amendments must be submitted during the period within which an existing permit is active and at least 30 days prior to the desired effect date of the amendment. Time-sensitive or non-substantive amendments must be submitted in writing to the point of contact included in the permit and will be considered and expedited on a case-by-case basis.

(b) Permit holders desiring to continue research activities beyond the original permit expiration date must apply for an extension of a valid permit prior to its expiration. A pending extension request does not guarantee an extension of the original permit. All requests for a permit extension must be sent to the Deputy Director, Naval History and Heritage Command, 805 Kidder Breese St. SE., Washington Navy Yard, Washington, DC 20374-5060, at least 30 days prior to the original permit's expiration date. Reference to the original application may be given in lieu of a new application, provided the scope of work does not change significantly. Applicants may apply for one-year extensions subject to annual review.

(c) Permit holders may appeal denied requests for amendments or extensions to the appeal authority listed in § 767.7(e).
