The Secretary shall, from time to time, prepare and transmit to the Committee on Natural Resources of the House of Representatives and the Committee on Energy and Natural Resources of the Senate reports on individual sites and structures identified in a survey under subsection (a), together with the Secretary’s recommendation as to whether the site or structure is suitable for establishment as a national historic site or national memorial to commemorate a former President. Each report shall include pertinent information with respect to the need for acquisition of land and interests in land, the development of facilities, and the operation and maintenance of the site or structure and the estimated cost of the operation and maintenance.

If during the 6-month period following the transmittal of a report pursuant to subsection (b) neither Committee has by vote of a majority of its members disapproved a recommendation of the Secretary that a site or structure is suitable for establishment as a national historic site, the Secretary may by appropriate order establish the site or structure as a national historic site, including the land and interests in land identified in the report accompanying the recommendation of the Secretary.

The Secretary may acquire the land and interests in land by donation, purchase with donated or appropriated funds, transfer from any other Federal agency, or exchange.

Nothing in this section shall be construed as diminishing the authority of the Secretary under chapter 3201 of this title or as authorizing the Secretary to establish any national memorial, creation of which is expressly reserved to Congress.
