(a) Volume limitations. When it is determined by the authorized officer to be in the public interest and when it is impracticable to obtain competition, mineral materials not exceeding 100,000 cubic yards in volume (or weight equivalent) may be sold in any one sale at not less than the appraised value, without advertising or calling for bids, except as provided in paragraphs (b) and (c) of this section. The authorized officer may not approve noncompetitive sales that exceed the total of 200,000 cubic yards (or weight equivalent) made in any one State for the benefit of any applicant in any period of 12 consecutive months.

(b) Government programs. In connection with a public works improvement project on behalf of a Federal, State, or local governmental agency, the authorized officer may sell to an applicant, at not less than the appraised value, without advertising or calling for bids, a volume of mineral materials not to exceed 200,000 cubic yards (or weight equivalent) when the public exigency will not permit delays incident to advertising (30 U.S.C. 602).

(c) Appropriation for highway purposes. For interstate and/or Federal aid highways, the Secretary of Transportation may appropriate any volume in accordance with 23 U.S.C. 107 and 317.

(d) Use in development of Federal mineral leases. When it is determined to be impracticable to obtain competition and the mineral materials are to be used in connection with the development of mineral leases issued by the United States (§ 228.44), the authorized officer may sell to a leaseholder a volume of mineral material not to exceed 200,000 cubic yards (or weight equivalent) in one State in any period of 12 consecutive months. No charge will be made for materials which must be moved in the process of extracting the mineral under lease, as long as the materials remain stockpiled within the boundaries of the leased area.
