Section 74:29:11:04 - Application content requirements - Reclamation plan

All procedurally complete applications for an in situ leach mine permit shall include, at a minimum, the information and materials related to reclamation required in SDCL 45-6B-5 to 45-6B-7, inclusive; 45-6B-37 to 45-6B-46, inclusive; and §§ 74:29:02:08; 74:29:02:10; 74:29:06:01; 74:29:07:01 to 74:29:07:27, inclusive; and 74:29:08:01 to 74:29:08:03, inclusive; and:

(1) Discussion and information necessary to demonstrate that the operation will achieve ground water restoration, including:

(a) A list of the proposed wellfields or mining units;

(b) A map showing the estimated sequence for restoration of the wellfields;

(c) A potentiometric map of the ground water surface in the producing zone and adjacent aquifers;

(d) The geochemistry of the production zone and of up-gradient and down-gradient aquifers, to include oxidation-reduction conditions and common ions;

(e) The direction and velocity of ground water movement through the producing zone;

(f) The proposed methods to restore ground water quality, based on the geochemistry of the production zone and the chemistry of the mining solutions;

(g) An estimated time schedule for the restoration of each wellfield; and

(h) A proposed restoration table for all ground water quality restoration values;

(2) A plan for well repair, abandonment, plugging, and conversion;

(3) A plan for the disposal of drill cuttings;

(4) An estimated time schedule for achieving reclamation, including ground water restoration and reclamation of surface disturbances in any mining area, to be carried to completion within five years in accordance with SDCL 45-6B-46;

(5) Procedures for reestablishing any surface water quality and surface drainage that may be impacted by the mining operation;

(6) Procedures for permanently disposing of any radioactive, toxic, or acid-forming materials;

(7) Procedures for removing and disposing of structures used in conjunction with the mining operation;

(8) Procedures for mitigating or controlling the effects of subsidence;

(9) The removal and proper disposal of sludges from impoundments;

(10) The removal and proper disposal of geomembranes from impoundments; and

(11) The estimated costs for reclamation as computed in accordance with established engineering principles, including:

(a) The cost of removing and disposing of structures;

(b) The cost of regrading, topsoiling, and reseeding all affected lands;

(c) The cost of facilities, materials, and chemicals used for ground water restoration;

(d) The cost of ground water restoration in the production zone;

(e) The cost of water treatment;

(f) The cost of capping, plugging, and sealing of all wells;

(g) The cost for collecting and analyzing samples from surface and ground water monitoring sites;

(h) The cost for disposing of solid or hazardous waste such as pond sludges or uranium byproduct material handling and disposal systems, including costs for on-site disposal systems; and

(i) The cost for personnel working on reclamation-related activities.
