(a)
Notice of intention to relinquish— If, during the period of withdrawal and reservation under section 2, the Secretary of the Army decides to relinquish any or all of the lands withdrawn and reserved, the Secretary of the Army shall file a notice of intention to relinquish with the Secretary of the Interior.
(b)
Determination of contamination— As a part of the notice under subsection (a), the Secretary of the Army shall include a written determination concerning whether and to what extent the lands that are to be relinquished are contaminated with explosive materials or toxic or hazardous substances.
(c)
Public notice— The Secretary of the Interior shall publish in the Federal Register the notice of intention to relinquish, including the determination concerning the contaminated state of the lands.
(d)
Decontamination of lands to be relinquished—
(1)
If land subject of a notice of intention to relinquish pursuant to subsection (a) is contaminated, and the Secretary of the Interior, in consultation with the Secretary of the Army, determines that decontamination is practicable and economically feasible (taking into consideration the potential future use and value of the land) and that, upon decontamination, the land could be opened to operation of some or all of the public land laws, including the mining laws and the mineral leasing and geothermal leasing laws, the Secretary of the Army shall decontaminate the land to the extent that funds are appropriated for such purpose.
(2)
If the Secretary of the Interior, after consultation with the Secretary of the Army, concludes that decontamination of land subject of a notice of intention to relinquish pursuant to subsection (a) is not practicable or economically feasible, or that the land cannot be decontaminated sufficiently to be opened to operation of some or all of the public land laws, or if Congress does not appropriate sufficient funds for the decontamination of such land, the Secretary of the Interior shall not be required to accept the land proposed for relinquishment.
(3)
If the Secretary of the Interior declines to accept the lands that have been proposed for relinquishment because of their contaminated state, or if at the expiration of the withdrawal and reservation made by section 2 the Secretary of the Interior determines that some of the lands withdrawn and reserved are contaminated to an extent which prevents opening such contaminated lands to operation of the public land laws—
(A)
the Secretary of the Army shall take appropriate steps to warn the public of the contaminated state of such lands and any risks associated with entry onto such lands;
(B)
after the expiration of the withdrawal and reservation, the Secretary of the Army shall undertake no activities on such lands except in connection with decontamination of such lands; and
(C)
the Secretary of the Army shall report to the Secretary of the Interior and to the Congress concerning the status of such lands and all actions taken in furtherance of this paragraph.
(e)
Revocation authority— Upon deciding that it is in the public interest to accept the lands proposed for relinquishment pursuant to subsection (a), the Secretary of the Interior may order the revocation of the withdrawal and reservation made by section 2 as it applies to such lands. The Secretary of the Interior shall publish in the Federal Register the revocation order, which shall—
(1)
terminate the withdrawal and reservation;
(2)
constitute official acceptance of the lands by the Secretary of the Interior; and
(3)
state the date upon which the lands will be opened to the operation of some or all of the public land laws, including the mining laws.
(f)
Acceptance by Secretary of the Interior— Nothing in this section shall be construed to require the Secretary of the Interior to accept the lands proposed for relinquishment if the Secretary determines that such lands are not suitable for return to the public domain. If the Secretary makes such a determination, the Secretary shall provide notice of the determination to Congress.
