The Secretary of the Interior shall issue quitclaim deeds to the public-land States for all lands patented to such States under section 641 of this title. He shall also issue a patent for all unpatented public lands within each State now segregated under that section for which the State issued final certificates or other evidence of right prior to June 1, 1953, or as to which equitable claims to the lands accrued prior to that date (by reason of cultivation or improvement of the lands for agricultural development purposes) for conveyance to the holders of such rights or claims, or to their heirs, successors, or assigns.

The Secretary shall not issue such quitclaim deeds or patents to any State, however, unless that State files a proper application for the transfer of these lands within three years after August 13, 1954.

The application must include a list of all the lands which the State certifies should be transferred under the terms of section 641a of this title, the basis for the certification of each tract included, and a quitclaim or relinquishment of all right, title, and interest in the State to any and all other lands under section 641 of this title. Such quitclaim or relinquishment by the State shall not affect any private rights obtained from the State prior to August 13, 1954.

The quitclaim or relinquishment of all right, title, and interest by the State to any lands under sections 641a to 641d of this title shall not be effective until the Secretary has transferred the lands applied for under section 641a of this title. The Secretary shall provide for the administration and disposition under the public-land laws of the lands quitclaimed or relinquished by the States pursuant to sections 641a to 641d of this title.

Under any law heretofore or hereafter enacted by any State, providing for the reclamation of arid lands, in pursuance and acceptance of the terms of the grant made in section 641 of this title, a lien or liens is authorized to be created by the State to which such lands are granted and by no other authority whatever, and when created shall be valid on and against the separate legal subdivisions of land reclaimed, for the actual cost and necessary expenses of reclamation and reasonable interest thereon from the date of reclamation until disposed of to actual settlers; and when an ample supply of water is actually furnished in a substantial ditch or canal, or by artesian wells or reservoirs, to reclaim a particular tract or tracts of such lands, then patents shall issue for the same to such State without regard to settlement or cultivation: Provided, That in no event, in no contingency, and under no circumstances shall the United States be in any manner directly or indirectly liable for any amount of any such lien or liability, in whole or in part.
