Section 74:54:02:01 - Definitions

Words defined in SDCL 34A-2-2 have the same meaning when used in this chapter. In addition, terms used in this chapter mean:

(1) "Aquifer," a geologic formation, group of geologic formations, or part of a geologic formation that contains sufficient saturated permeable material to yield economical quantities of water to wells and springs;

(2) "Ambient," the constituents or parameters and the concentration or measurements which describe water quality prior to a subsurface discharge;

(3) "Board," the South Dakota Board of Water Management;

(4) "Compliance monitoring point," a well or wells located at the appropriate edge of the perimeter of operational pollution which is determined to be the earliest point of detection of a violation of a groundwater discharge plan;

(5) "EPA," the United States Environmental Protection Agency;

(6) "Contaminant," any physical, chemical, biological, or radiological substance or matter in water which is potentially harmful to human health;

(7) "Gradient," the change in total head per unit of distance;

(8) "Groundwater," water below the land surface that is in the zone of saturation;

(9) "Groundwater table," the upper surface of the zone of saturation of an unconfined aquifer;

(10) "Effluent," the discharge of partially or completely treated or untreated liquid waste;

(11) "Leachate," water that has percolated through solid waste or soils containing dissolved soluble substances and certain amounts of these substances in solution;

(12) "NPDES," the National Pollutant Discharge elimination system;

(13) "Owner and operator," person legally responsible for a facility subject to the provisions of this chapter;

(14) "Parameter," any physical, chemical, biological, or radiological constituent or characteristic of the groundwater, such as temperature, pH, and groundwater level;

(15) "Permitted allowable limit," the maximum groundwater contaminant concentration allowed at the compliance monitoring point as specified in the groundwater discharge permit;

(16) "Perimeter of operational pollution," "POP," a three-dimensional section of geologic materials surrounding the point of application of discharge within which groundwater quality degradation is permitted to occur;

(17) "Point of application," the outermost limit at which effluent or leachate has been stored, applied, disposed of, or discharged; for a diked facility, the outermost edge of the dikes;

(18) "Pollutant," dredged spoil, solid waste, incinerator residue, sewage, sewage sludge, garbage, trash, chemical waste, biological material, radioactive material, heat, wrecked or discarded equipment, rock, sand, or any industrial, municipal, or agricultural waste discharged into waters of the state;

(19) "Pollution," such contamination or other alteration of the physical, chemical, or biological properties of any waters of the state that exceeds that permitted by state effluent or water quality standards, or both, including change in temperature, taste, color, turbidity, or odor of the waters, or such discharge of any liquid, gaseous, solid, radioactive, or other substance into any waters of the state as will or is likely to create a nuisance or render such waters harmful, detrimental, or injurious to public health, safety, or welfare; or to domestic, commercial, industrial, agricultural, recreational, or other legitimate beneficial uses; or to livestock, wild animals, birds, fish, or other aquatic life;

(20) "Procedurally complete," an application for a groundwater discharge plan that contains all information necessary to fully address § 74:54:02:06;

(21) "Radius of influence," the radial distance from the center of a well bore to the point where there is no lowering of the water table or potentiometric surface because of pumping of the well; the edge of the cone of depression;

(22) "Secretary," the secretary of the Department of Environment and Natural Resources or a representative designated to act for the secretary;

(23) "Vadose zone," the zone containing water under pressure less than that of the atmosphere, including soil water, intermediate vadose water, and capillary water, limited above by the land surface and below by the surface of the zone of saturation or the water table;

(24) "Well," an artificial excavation or opening in the ground made by digging, boring, drilling, jetting, or another artificial method often walled or cased to prevent the sides from caving in, whose depth is greater than the largest surface dimension.
