Va. Code § 1-408
Whenever a duly authorized official or agent of the United States, acting pursuant to authority conferred by the United States Congress, notifies the Governor that the United States desires or is willing to relinquish to the Commonwealth the jurisdiction, or a portion thereof, held by the United States over lands located in the Commonwealth, as designated in such notice, the Governor may, in his discretion, accept such relinquishment. Such acceptance shall be made by sending a notice of acceptance to the official or agent designated by the United States to receive such notice of acceptance. The Governor shall send a signed copy of the notice of acceptance, together with the notice of relinquishment received from the United States, to the Secretary of the Commonwealth, who shall maintain a permanent file of said notices.
Upon the sending of the notice of acceptance to the designated official or agent of the United States, the Commonwealth shall immediately have such jurisdiction over the lands designated in the notice of relinquishment as the notice shall specify.
Upon receipt of a copy of the notice of relinquishment and a copy of the notice of acceptance, the Secretary of the Commonwealth shall immediately give written notice of such change in jurisdiction to the Attorney General and the attorney for the Commonwealth of the city or county in which such lands are located. The Secretary of the Commonwealth shall also certify a copy of each of the notices to the clerk of court in which deeds are admitted to record for the city or county in which such lands are located. The clerk shall record the notices in his deed book and index them in the name of the United States and the Commonwealth.
