Subject to valid existing rights, all Federal lands located in the special management areas are hereby withdrawn from all forms of entry, appropriation, or disposal under the public land laws, from location, entry, and patent under the mining laws of the United States, and from disposition under all laws pertaining to mineral and geothermal leasing: Provided, That the Secretary may allow the exploration, development, or production of sand, gravel, and crushed rock as necessary to construct, maintain, or reconstruct roads in the special management areas.
Upon receipt of notification of nonconcurrence by the Secretary, the Commission shall resubmit the land use ordinance to the appropriate county. Such county shall within ninety days, reconsider and revise the ordinance and resubmit the ordinance to the Commission for reconsideration in accordance with the provisions of this section. Should the Secretary again deny concurrence, the Commission shall either prepare a land use ordinance for such county pursuant to subsection (l) of this section or, by a two-thirds vote of the membership of the Commission including a majority of the members appointed from each State, determine that the ordinance is consistent with the management plan.
In the event the Commission has adopted an ordinance pursuant to this section, the affected county may thereafter, upon written notice to the Commission and to the Secretary, elect to adopt a special management area land use ordinance, in which event it shall comply with the provisions of this section for adoption of special management area land use ordinances. Upon concurrence of such land use ordinances by the Secretary they shall supersede any special management area land use ordinances for the county development by the Commission, subject to valid existing rights.
Any ordinance adopted pursuant to this section shall not apply to any parcel or parcels of land within a special management area if, after the date such ordinance has been adopted, three years have elapsed after a landowner has made a bona fide offer to sell at fair market value or otherwise convey such parcel or parcels to the Secretary, unless the affected landowner agrees to an extension of the three year period: Provided, That an offer shall not be considered bona fide if the landowner refuses consideration equal to the fair market value as appraised in accordance with section 544g(e) of this title. Lands for which an ordinance is suspended pursuant to this subsection shall be subject to the relevant scenic area land use ordinance adopted pursuant to section 544e of this title.
This subsection shall not apply to any land offered to the Secretary for acquisition after March 31, 2001.
