§ 101-47.103-12 - Real property.

(a) Any interest in land, together with the improvements, structures, and fixtures located thereon (including prefabricated movable structures, such as Butler-type storage warehouses and quonset huts, and housetrailers with or without undercarriages), and appurtenances thereto, under the control of any Federal agency, except:

(1) The public domain;

(2) Lands reserved or dedicated for national forest or national park purposes;

(3) Minerals in lands or portions of lands withdrawn or reserved from the public domain which the Secretary of the Interior determines are suitable for disposition under the public land mining and mineral leasing laws;

(4) Lands withdrawn or reserved from the public domain but not including lands or portions of lands so withdrawn or reserved which the Secretary of the Interior, with the concurrence of the Administrator of General Services, determines are not suitable for return to the public domain for disposition under the general public land laws because such lands are substantially changed in character by improvements or otherwise; and

(5) Crops when designated by such agency for disposition by severance and removal from the land.

(b) Improvements of any kind, structures, and fixtures under the control of any Federal agency when designated by such agency for disposition without the underlying land (including such as may be located on the public domain, or lands withdrawn or reserved from the public domain, or lands reserved or dedicated for national forest or national park purposes, or on lands that are not owned by the United States) excluding, however, prefabricated movable structures, such as Butler-type storage warehouses and quonset huts, and housetrailers (with or without undercarriages).

(c) Standing timber and embedded gravel, sand, or stone under the control of any Federal agency whether designated by such agency for disposition with the land or by severance and removal from the land, excluding timber felled, and gravel, sand, or stone excavated by or for the Government prior to disposition.
