16 U.S. Code § 410ii–3 - Acquisition of properties
The Secretary is authorized to acquire lands, waters, and interests therein within the boundaries of the Chaco Culture National Historical Park (hereinafter referred to as the “park”) and the archeological protection sites as identified in section 410ii–1 of this title by donation, purchase with donated or appropriated funds, or exchange. Property owned by the State of New Mexico or any political subdivision thereof, may be acquired by exchange or donation only. Property held in trust for the benefit of any Indian tribe or for the benefit of any individual member thereof may be acquired only with the consent of such owner or beneficial owner as the case may be.
The respective tribal authorities are authorized to convey by exchange, purchase, on  donation the beneficial interest in any lands designated by section 410ii–1 of this title and held in trust by the United States for the respective tribes, to the Secretary, subject to such terms and conditions as the tribal authority deems necessary and which the Secretary deems are consistent with the purposes of this subchapter.
All Federal lands, waters, and interests therein excluded from the boundaries of Chaco Canyon National Monument by this subchapter may be exchanged for non-Federal property to be acquired pursuant to this subchapter. Any lands so excluded shall be managed by the Secretary under the provisions of the Federal Land Policy and Management Act of 1976 [43 U.S.C. 1701 et seq.]. Transfer of administration of such lands to the Bureau of Land Management shall not be considered a withdrawal as that term is defined in section 103(j) of the Federal Land Policy and Management Act of 1976 [43 U.S.C. 1702(j)].
 So in original. Probably should be “or”.
The Federal Land Policy and Management Act of 1976, referred to in subsec. (e), is Pub. L. 94–579, Oct. 21, 1976, 90 Stat. 2743, as amended, which is classified principally to chapter 35 (§ 1701 et seq.) of Title 43, Public Lands. For complete classification of this Act to the Code, see Short Title note set out under section 1701 of Title 43 and Tables.
1995—Subsec. (c)(2). Pub. L. 104–11 amended par. (2) generally. Prior to amendment, par.
