Amends the National Historic Preservation Act to require the Secretary of the Interior to notify the House Committee on Natural Resources and the Senate Committee on Energy and Natural Resources if a property owned by the federal government is being considered for inclusion on the National Register, for designation as a National Historic Landmark, or for nomination to the World Heritage List. Prohibits such inclusion or designation of federal property if the head of any federal agency managing such property objects to such inclusion or designation for national security reasons.
