Section 74:29:02:11 - Effect on hydrologic balance and on surface water and groundwater

For SDCL 45-6B-41, the following information may be required to address the potential impact to the hydrologic balance of the affected land and to determine if a groundwater discharge plan is required pursuant to chapter 74:54:02 or a surface water discharge permit (SWD) is required pursuant to chapter 74:52:01:

(1) A baseline surface and groundwater report, including a description of the aquifers potentially affected by the operation, the geology of the area of affected land, surface and groundwater quality and quantity, groundwater level data, surface water discharge rates, ground water gradients, groundwater recharge and discharge areas, meteorologic data, and other information necessary to characterize the hydrologic system;
(2) Representative geologic cross-sections;
(3) A surface water inventory map on a topographic base map, depicting all identifiable surface water resources potentially affected by the operation, including seeps, springs, rivers, streams, lakes, ponds, wetlands, and dams;
(4) A well location inventory map depicting any identifiable wells, excluding exploration test holes, located within one mile of the boundary of the permit area;
(5) A potentiometric surface map on a topographic base map;
(6) A geochemical characterization of ore and waste rock. At a minimum, the EP Toxicity test shall be used;
(7) A surface and groundwater monitoring plan for the life of the mine;
(8) A meteorologic monitoring plan;
(9) A drainage, erosion, and sedimentation control plan;
(10) For operations using chemicals in the milling process, a description of the proposed methods to monitor and collect leakage or spills and a spill contingency plan;
(11) An estimate of the project water requirements including flow rates and volumes for each phase of the operation. This estimate must include a description of the potential affect on the quality and quantity of the proposed water source;
(12) A description of the chemical characteristics of process solutions and the chemicals used to process ore, including a range of operating concentrations; and
(13) Preliminary engineering plans and specifications for pollution control facilities and a quality assurance/quality control plan for the construction of such facilities.
