(a) If the issuance of a permit under this part may result in harm to, or destruction of, any Indian tribal religious or cultural site on public lands, as determined by the Commissioner, at least 30 days before issuing such a permit the Commissioner shall notify any Indian tribe which may consider the site as having religious or cultural importance. Such notice shall not be deemed a disclosure to the public for purposes of section 9 of the Act.

(1) Notice by the Commissioner to any Indian tribe shall be sent to the chief executive officer or other designated official of the tribe. Indian tribes are encouraged to designate a tribal official to be the focal point for any notification and discussion between the tribe and the Commissioner.

(2) The Commissioner may provide notice to any other Native American group that is known by the Commissioner to consider sites potentially affected as being of religious or cultural importance.

(3) Upon request during the 30-day period, the Commissioner may meet with official representatives of any Indian tribe or group to discuss their interests, including ways to avoid or mitigate potential harm or destruction such as excluding sites from the permit area. Any mitigation measures which are adopted shall be incorporated into the terms and conditions of the permit under § 1104.8.

(4) When the Commissioner determines that a permit applied for under this part must be issued immediately because of an imminent threat of loss or destruction of an archaeological resource, the Commissioner shall so notify the appropriate tribe.

(b)(1) In order to identify sites of religious or cultural importance, the Commissioner shall seek to identify all Indian tribes having aboriginal or historic ties to the lands under the Commissioner's jurisdiction and seek to determine, from the chief executive officer or other designated official of any such tribe, the location and nature of specific sites of religious or cultural importance so that such information may be on file for land management purposes. Information on site eligible for or included in the National Register of Historic Places may be withheld from public disclosure pursuant to section 304 of the Act of October 15, 1966, as amended (16 U.S.C. 470w-3).

(2) If the Commissioner becomes aware of a Native American group that is not an Indian tribe as defined in this part but has aboriginal or historic ties to public lands under the Commissioner's jurisdiction, the Commissioner may seek to communicate with official representatives of that group to obtain information on sites they may consider to be of religious or cultural importance.

(3) The Commissioner may enter into agreement with any Indian tribe or other Native American group for determining locations for which such tribe or group wishes to receive notice under this section.
