The governor shall deliver the documents executed by the federal authority and the governor concurring in the retrocession, for recording, to the office of the recorder of the county in which the lands are located.

(C) The granting of exclusive or concurrent jurisdiction to the United States pursuant to division (A) of this section shall take effect only upon the granting of either form of jurisdiction by the governor to the United States and the acceptance of either form of jurisdiction by the United States.

(D) Nothing in this section is intended to modify, revoke, or in any way affect any prior grant of jurisdiction by the state to the United States that was made prior to the effective date of this amendment.
