49 U.S.C. § 47151: Authority to transfer an interest in surplus property

desirable for developing, improving, operating, or maintaining a public airport (as defined in section 47102 of this title ); reasonably necessary to fulfill the immediate and foreseeable future requirements for developing, improving, operating, or maintaining a public airport; or needed for developing sources of revenue from nonaviation businesses at a public airport; and if the Administrator of General Services approves the conveyance and decides the interest is not best suited for industrial use. Only the Secretary may ensure compliance with an instrument conveying an interest in surplus property under this subchapter. The Secretary may amend the instrument to correct the instrument or to make the conveyance comply with law. An interest in surplus property that could be used at a public airport but that is not conveyed under this subchapter shall be disposed of under other applicable law. will not significantly impair the aeronautical purpose of an airport; will not result in the permanent closure of an airport (unless the Secretary determines that the waiver will directly facilitate the construction of a replacement airport); or is necessary to protect or advance the civil aviation interests of the United States. Except with respect to a request made by another department, agency, or instrumentality of the executive branch of the United States Government, such a department, agency, or instrumentality shall give priority consideration to a request made by a public agency (as defined in section 47102) for surplus property described in subsection (a) for use at a public airport.
