(5)(A) The agreement shall require the entity or entities to transfer to the United States, upon the request of the Secretary concerned, all or a portion of the property or interest acquired under the agreement or a lesser interest therein. No such requirement need be included in the agreement if the property or interest is being transferred to a State or another Federal agency, or the agreement requires it to be subsequently transferred to a State or another Federal agency, and the Secretary concerned determines that the laws and regulations applicable to the future use of such property or interest provide adequate assurance that the property concerned will be developed and used in a manner appropriate for purposes of this section.

If the Secretary concerned determines it necessary to preserve the purposes of this section, the Secretary concerned may request that administrative jurisdiction over the property be transferred to the Secretary concerned at no cost, and, upon such a request being made, the administrative jurisdiction over the property shall be transferred accordingly. If the Secretary concerned does not make such a request within a reasonable time period, all such rights of the Secretary concerned to request transfer of the property or interest shall remain available to the Secretary concerned with respect to future transfers or exchanges of the property or interest and shall bind all subsequent transferees.
