"(6) A conveyance under this subsection shall be subject to the following conditions: "(A) Except as otherwise provided in subparagraphs (B) and (D) of this paragraph, the document of conveyance shall provide that the lands conveyed under this subsection shall revert to the United States, unless substantially all of the lands have been used, on or before the date five years after the date of conveyance, for the purpose or purposes specified in the application, or for other use or uses authorized under section 3(a) with the consent of the Secretary.
