Notwithstanding any other provision of law, within the boundaries of the park as revised by and pursuant to sections 251e to 251m of this title, the Secretary is authorized to acquire lands, privately owned aquatic lands, and interests therein by donation, purchase with donated or appropriated funds, exchange, or transfer from any Federal agency. Property so acquired shall become part of Olympic National Park and shall be administered by the Secretary subject to the laws and regulations applicable to such park. The Secretary is authorized and directed to exclude from the boundaries of the park such private lands and publicly owned and maintained roads within Grays Harbor County which are near and adjacent to Lake Quinault, and which do not exceed two thousand, one hundred and sixty-eight acres in total. Prior to excluding such lands from the park, the Secretary shall study and investigate current and prospective uses of the private lands, as well as the implications of their exclusion both for the lands involved and for Olympic National Park. The results of such study shall be transmitted to the President and to the Congress within two years of October 21, 1976, and shall take effect unless disapproved by simple majority vote of the House of Representatives or the Senate of the United States of America within ninety legislative days of their submission to the Congress. Property excluded from the boundaries of the park by sections 251e to 251m of this title may be exchanged for non-Federal property within the boundaries; or it may be transferred to the jurisdiction of any Federal agency or to the State of Washington or a political subdivision thereof, without monetary consideration, as the Secretary may deem appropriate. Any such Federal property transferred to the jurisdiction of the Secretary of Agriculture for national forest purposes shall upon such transfer become part of the national forest and subject to the laws and regulations pertaining thereto. Any property excluded from the park by sections 251e to 251m of this title which is within the boundaries of an Indian reservation may be transferred in trust to such Indian tribe, subject, however, to the express condition that any concessioner providing, public services shall be permitted to continue to provide such services in such manner and for such period as set forth in his concession contract, that the Secretary of the Interior is authorized to pay all franchise fees collected from the concessioner under the contract to said Indian Tribe, and that in the event his contract is terminated, the United States shall purchase his possessory interest in accordance with the Act of October 9, 1965 (79 Stat. 969).1
