((a)) ** Findings of fact; notice; right of entry** If the Secretary or the State pursuant to an approved State program, makes a finding of fact that—
((1)) land or water resources have been adversely affected by past coal mining practices; and
((2)) the adverse effects are at a stage where, in the public interest, action to restore, reclaim, abate, control, or prevent should be taken; and
((3)) the owners of the land or water resources where entry must be made to restore, reclaim, abate, control, or prevent the adverse effects of past coal mining practices are not known, or readily available; or
((4)) the owners will not give permission for the United States, the States, political subdivisions, their agents, employees, or contractors to enter upon such property to restore, reclaim, abate, control, or prevent the adverse effects of past coal mining practices;
((b)) ** Studies or exploratory work** The Secretary, his agents, employees, or contractors or the State pursuant to an approved State program, shall have the right to enter upon any property for the purpose of conducting studies or exploratory work to determine the existence of adverse effects of past coal mining practices and to determine the feasibility of restoration, reclamation, abatement, control, or prevention of such adverse effects. Such entry shall be construed as an exercise of the police power for the protection of public health, safety, and general welfare and shall not be construed as an act of condemnation of property nor trespass thereon.
((c)) ** Requirements for acquisition of affected land** The Secretary or the State pursuant to an approved State program, may acquire any land, by purchase, donation, or condemnation, which is adversely affected by past coal mining practices if the Secretary determines that acquisition of such land is necessary to successful reclamation and that—
((1)) the acquired land, after restoration, reclamation, abatement, control, or prevention of the adverse effects of past coal mining practices, will serve recreation and historic purposes, conservation and reclamation purposes or provide open space benefits; and
((2)) permanent facilities such as a treatment plant or a relocated stream channel will be constructed on the land for the restoration, reclamation, abatement, control, or prevention of the adverse effects of past coal mining practices; or
((3)) acquisition of coal refuse disposal sites and all coal refuse thereon will serve the purposes of this subchapter or that public ownership is desirable to meet emergency situations and prevent recurrences of the adverse effects of past coal mining practices.
((d)) ** Title to affected land; value** Title to all lands acquired pursuant to this section shall be in the name of the United States or, if acquired by a State pursuant to an approved program, title shall be in the name of the State. The price paid for land acquired under this section shall reflect the market value of the land as adversely affected by past coal mining practices.
((e)) ** State participation; grants** States are encouraged as part of their approved State programs, to reclaim abandoned and unreclaimed mined lands within their boundaries and, if necessary, to acquire or to transfer such lands to the Secretary or the appropriate State regulatory authority under appropriate Federal regulations. The Secretary is authorized to make grants on a matching basis to States in such amounts as he deems appropriate for the purpose of carrying out the provisions of this subchapter but in no event shall any grant exceed 90 per centum of the cost of acquisition of the lands for which the grant is made. When a State has made any such land available to the Federal Government under this subchapter, such State shall have a preference right to purchase such lands after reclamation at fair market value less the State portion of the original acquisition price. Notwithstanding the provisions of paragraph (1) of subsection (c), reclaimed land may be sold to the State or local government in which it is located at a price less than fair market value, which in no case shall be less than the cost to the United States of the purchase and reclamation of the land, as negotiated by the Secretary, to be used for a valid public purpose. If any land sold to a State or local government under this paragraph is not used for a valid public purpose as specified by the Secretary in the terms of the sales agreement then all right, title, and interest in such land shall revert to the United States. Money received from such sale shall be deposited in the fund.
((f)) ** Rules and regulations** The Secretary, in formulating regulations for making grants to the States to acquire land pursuant to this section, shall specify that acquired land meet the criteria provided for in subsections (c) and (d) of this section. The Secretary may provide by regulation that money derived from the lease, rental, or user charges of such acquired land and facilities thereon will be deposited in the fund.
((g)) ** Public sale; notice and hearing**
((1)) Where land acquired pursuant to this section is deemed to be suitable for industrial, commercial, residential, or recreational development, the Secretary may sell or authorize the States to sell such land by public sale under a system of competitive bidding, at not less than fair market value and under such other regulations promulgated to insure that such lands are put to proper use consistent with local and State land use plans, if any, as determined by the Secretary.
((2)) The Secretary or the State pursuant to an approved State program, when requested after appropriate public notice shall hold a public hearing, with the appropriate notice, in the county or counties or the appropriate subdivisions of the State in which lands acquired pursuant to this section are located. The hearings shall be held at a time which shall afford local citizens and governments the maximum opportunity to participate in the decision concerning the use or disposition of the lands after restoration, reclamation, abatement, control, or prevention of the adverse effects of past coal mining practices.
((h)) ** Construction or rehabilitation of housing for disabled, displaced, or dislocated persons; grants** In addition to the authority to acquire land under subsection (d) of this section the Secretary is authorized to use money in the fund to acquire land by purchase, donation, or condemnation, and to reclaim and transfer acquired land to any State or to a political subdivision thereof, or to any person, firm, association, or corporation, if he determines that such is an integral and necessary element of an economically feasible plan for the project to construct or rehabilitate housing for persons disabled as the result of employment in the mines or work incidental thereto, persons displaced by acquisition of land pursuant to this section, or persons dislocated as the result of adverse effects of coal mining practices which constitute an emergency as provided in or persons dislocated as the result of natural disasters or catastrophic failures from any cause. Such activities shall be accomplished under such terms and conditions as the Secretary shall require, which may include transfers of land with or without monetary consideration: , That, to the extent that the consideration is below the fair market value of the land transferred, no portion of the difference between the fair market value and the consideration shall accrue as a profit to such persons, firm, association, or corporation. No part of the funds provided under this subchapter may be used to pay the actual construction costs of housing. The Secretary may carry out the purposes of this subsection directly or he may make grants and commitments for grants, and may advance money under such terms and conditions as he may require to any State, or any department, agency, or instrumentality of a State, or any public body or nonprofit organization designated by a State.section 1240 of this titleProvided
