Inasmuch as the Kanosh, Koosharem and Indian Peaks Bands of Paiute Indians lost land which had been their former reservations and the Cedar Band of Paiute Indians had never had a reservation, the Secretary shall negotiate with the tribe or bands, or with representatives of the tribe chosen by the tribe or bands, concerning the enlargement of the reservation for the tribe established pursuant to subsection (a) of this section and shall within two years after April 3, 1980, develop a plan for the enlargement of the reservation for the tribe. The plan shall include acquisition of not to exceed a total of fifteen thousand acres of land to be selected from available public, State, or private lands within Beaver, Iron, Millard, Sevier, or Washington Counties, Utah. Upon approval of such plan by the tribal officials elected under the tribal constitution and bylaws adopted pursuant to section
765 of this title, the Secretary shall submit such plan, in the form of proposed legislation, to the Congress.
