§ 216.1 Purpose.

It is the policy of this Department to encourage the development of the mineral resources underlying Indian lands where mining is authorized. However, interest of the Indian owners and the public at large requires that, with respect to the exploration for, and the surface mining of, such minerals, adequate measures be taken to avoid, minimize, or correct damage to the environment-land, water, and air-and to avoid, minimize, or correct hazards to the public health and safety. The regulations in this part prescribe procedures to that end.

§ 216.2 Scope.

(a) Except as provided in paragraph (b) of this section, the regulations in this part provide for the protection and conservation of nonmineral resources during operations for the discovery, development, surface mining, and onsite processing of minerals under permits or leases issued pursuant to statutes pertaining to Indian lands including but not limited to the following statutes or amendments thereto:

(h) "Reclamation" means measures undertaken to bring about the necessary reconditioning or restoration of land or water that has been affected by exploration or mineral development, mining or onsite processing operations, and waste disposal, in ways which will prevent or control onsite and offsite damage to the environment.

§ 216.4 Technical examination of prospective surface exploration and mining operations.

(a)(1) In connection with an application for a permit or lease, the superintendent shall make, or cause to be made, a technical examination of the prospective effects of the proposed exploration or surface mining operations upon the environment. The technical examination shall take into consideration the need for the preservation and protection of other resources, including cultural, recreational, scenic, historic, and ecological values; and control of erosion, flooding, and pollution of water; the isolation of toxic materials; the prevention of air pollution; the reclamation by revegetation, replacement of soil or by other means, of lands affected by the exploration or mining operations; the prevention of slides; the protection of fish and wildlife and their habitat; and the prevention of hazards to public health and safety.

(2) A technical examination of an area should be made with the recognition that actual potential mining sites and mining operations vary widely with respect to topography, climate, surrounding land uses, proximity to densely used areas, and other environmental influences and that mining and reclamation requirements should provide sufficient flexibility to permit adjustment to local conditions.

(b) Based upon the technical examination, the superintendent shall formulate the general requirements which the applicant must meet for the protection of nonmineral resources during the conduct of exploration or mining operations and for the reclamation of lands or waters affected by exploration or mining operations. The general requirements shall be made known in writing to the applicant before the issuance of a permit or lease and upon acceptance thereof by the applicant, shall be incorporated in the permit or lease.

(c) In each instance in which an application is made the mining supervisor shall participate in the technical examination and in the formulation of the general requirements.

(d) The superintendent may prohibit or otherwise restrict operations on any

part of an area whenever it is determined that such part of the area described in an application for a permit or lease is such that previous experience under similar conditions has shown that operations cannot feasibly be conducted by any known methods or measures to avoid

(1) Rock or landslides which would be a hazard to human lives or endanger or destroy private or public property; or

(2) Substantial deposition of sediment and silt into streams, lakes, reservoirs; or

(3) A lowering of water quality below standards established by the appropriate State water pollution control agency, or by the Secretary of the Interior, or his authorized representative; or

(4) A lowering of the quality of waters whose quality exceeds that required by the established standardsunless and until it has been affirmatively demonstrated to the Secretary of the Interior, or his authorized representative, that such lowering of quality is necessary to economic and social development and will not preclude any assigned uses made of such waters; or

(5) The destruction of key wildlife habitat or important scenic, historical, or other natural or cultural features.

(e) If, on the basis of a technical examination, the superintendent determines that there is a likelihood that there will be a lowering of water quality as described in paragraphs (d) (3) and (4) of this section caused by the operation, no lease or permit shall be issued until after consultation with the Federal Water Pollution Control Administration and a finding by the Administration that the proposed operation would not be in violation of the Federal Water Pollution Control Act, as amended (33 U.S.C. 466 et seq.), or of Executive Order No. 11288 (31 FR 9261). Where a permit or lease is involved the Superintendent's determination shall be made in consultation with the mining supervisor.

(7) A statement of the proposed manner and time of performance of

work to reclaim areas disturbed by the holder's operation.

(c) In those instances in which the permit or lease requires the revegetation of an area of land to be affected, the mining plan shall show:

(1) Proposed methods of preparation and fertilizing the soil prior to replanting;

(2) Types and mixtures of shrubs, trees, or tree seedlings, grasses or legumes to be planted; and

(3) Types and methods of planting, including the amount of grasses or legumes per acre, or the number and spacing of trees, or tree seedlings, or combinations of grasses and trees.

(d) In those instances in which the permit or lease requires regrading and backfilling, the mining plan shall show the proposed methods and the timing of grading and backfilling of areas of land to be affected by the operation.

(e) The mining supervisor shall review the mining plan submitted to him by the operator and shall promptly indicate to the operator any changes, additions, or amendments necessary to meet the requirements formulated pursuant to § 216.4, the provisions of these regulations and the terms of the permit or lease. The operator shall comply with the provisions of an approved mining plan.

(f) A mining plan may be changed by mutual consent of the mining supervisor and the operator at any time to adjust to changed conditions or to correct any oversight. To obtain approval of a change or supplemental plan, the operator shall submit a written statement of the proposed changes or supplement and the justification for the changes proposed. The mining supervisor shall promptly notify the operator that he consents to the proposed changes or supplement, or in the event he does not consent, he shall specify the modifications thereto under which the proposed changes or supplement would be acceptable. After mutual acceptance of a change of a plan, the operator shall not depart therefrom without further approval.

(g) If circumstances warrant or if development of a mining plan for the entire operation is dependent upon unknown factors which cannot or will not be determined except during the

(a) Upon approval of an exploration plan or mining plan, the operator shall be required to file a suitable performance bond of not less than $2,000 with satisfactory surety, payable to the Secretary of the Interior, and the bond shall be conditioned upon the faithful compliance with applicable regulations, the terms and conditions of the permit, lease, or contract, and the exploration or mining plan as approved, amended or supplemented. The bond shall be in an amount sufficient to satisfy the reclamation requirements established pursuant to an approved exploration or mining plan, or an approved partial or supplemental plan. In determining the amount of the bond consideration shall be given to the character and nature of the reclamation requirements and the estimated costs of reclamation in the event that the operator forfeits his performance bond. In lieu of a surety bond an operator may elect to deposit cash or negotiable bonds of the U.S. government. The cash deposit or the market value of such securities shall be equal at least to the required sum of the bond.

(b) In a particular instance where the circumstances are such as to warrant an exception, the amount of the bond for a particular operation may be reduced to less than the required minimum of $2,000.

(c) The superintendent shall set the amount of a bond and take the necessary action for an increase or for a complete or partial release of a bond. He shall take action with respect to bonds for leases or permits only after consultation with the mining supervi

sor.
