Section 69-05.2-08-06 - Permit applications - Permit area - Ground water information1. The applicant shall analyze the ground water hydrology and ground water resources of the potentially affected area. The application must contain a description of the ground water hydrology for the permit and adjacent areas including:a. A general account of the ground water hydrology (the water resources of the area).b. Known uses of the water in the aquifers and water table and location of all water wells within the permit and adjacent areas.c. Sufficient information and narratives to adequately describe the recharge, storage, and discharge characteristics of aquifers and the quality and quantity of ground water according to the parameters and in the detail required by the commission. The narrative must discuss the aquifers and hydrologic functions that are addressed in the ground water monitoring plan required by section 69-05.2-09-12 in order to comply with sections 69-05.2-16-13 through 69-05.2-16-15.d. Contour maps or maps showing the water table or piezometric surface in each aquifer (including water-bearing coal or commercial leonardite seams) down to and including the lowest water-bearing coal or commercial leonardite seam to be mined and any lower aquifer which may be adversely affected by mining. The applicant shall prepare 1:24,000 scale maps covering the permit and adjacent areas, using at least one data point (a piezometer nest) per four square miles [6.44 square kilometers], unless the commission requires a greater density. Data points must be shown on the map to the nearest ten acres [4.05 hectares]. Accompanying data should include lithologic and geophysical (gamma ray and density) logs of the piezometer holes, piezometer construction details, and water level and land surface elevations to the accuracy necessary for valid analysis of the ground water hydrology of the permit and adjacent areas.e. Results of water samples collected from each data point, if possible, analyzed for: (1) Total dissolved solids in milligrams per liter.(2) Hardness in milligrams per liter.(3) Sodium in milligrams per liter.(4) Iron, bicarbonate, nitrate, sulfate, and chloride in milligrams per liter.(5) pH in standard units.(6) Sodium adsorption ratio (include calcium, magnesium, and sodium cation concentrations).(7) Electrical conductivity in micro mhos per centimeter.(8) Additional parameters required by the commission on a site-specific basis.2. If necessary, the applicant shall provide additional ground water information required by subsections 5 and 6 of section 69-05.2-08-04.3. The applicant shall meet the alluvial valley floor ground water information and data requirements if the permit area contains or is adjacent to an identified alluvial valley floor.N.D.
