Current through Register Vol. 40, No. 24, July 15, 2024
(a)
				  Sampling and analysis. All water quality analyses performed to meet the
				  requirements of this section shall be conducted according to the methodology in
				  the current edition of "Standard Methods for the Examination of Water and
				  Wastewater," which is incorporated by reference, or the methodology in 40 CFR
				  Parts 136 and 434. Water quality sampling performed to meet the requirements of
				  this section shall be conducted according to either methodology listed above
				  when feasible.
(b) Baseline
				  information. The application shall include the following baseline hydrologic
				  information, and any additional information required by the division.
(1) Groundwater information. The location and
				  ownership for the permit and adjacent areas of existing wells, springs, and
				  other groundwater resources, seasonal quality and quantity of groundwater, and
				  usage. Water quality descriptions shall include, at a minimum, total dissolved
				  solids or specific conductance corrected to 25°C, pH, total iron, and total
				  manganese. Groundwater quantity descriptions shall include, at a minimum,
				  approximate rates of discharge or usage and elevation of water in the coal
				  seam, and each water-bearing stratum above and potentially impacted stratum
				  below the coal seam.
(2) Surface
				  water information. The name, location, ownership and description of all surface
				  water bodies such as streams, lakes, and impoundments, the location of any
				  discharge into any surface water body in the proposed permit and adjacent
				  areas, and information on surface water quality and quantity sufficient to
				  demonstrate seasonal variation and water usage. Water quality descriptions
				  shall include, at a minimum, baseline information on total suspended solids,
				  total dissolved solids or specific conductance corrected to 25°C, pH, total
				  iron, and total manganese. Baseline acidity and alkalinity information shall be
				  provided if there is a potential for acid drainage from the proposed mining
				  operation. Water quantity descriptions shall include, at a minimum, baseline
				  information on seasonal flow rates.
(3) Supplemental information. If the
				  determination of the probable hydrologic consequences (PHC) required by
				  subsection (e) of this section indicates that adverse impacts on or off the
				  proposed permit area may occur to the hydrologic balance, or that acid-forming
				  or toxic-forming material is present that may result in the contamination of
				  groundwater or surface water supplies, then information supplemental to that
				  required under subdivisions (b)(1) and (b)(2) of this section shall be provided
				  to evaluate such probable hydrologic consequences and to plan remedial and
				  reclamation activities. Such supplemental information may be based upon
				  drilling, aquifer tests, hydrogeologic analysis of the water-bearing strata,
				  flood flows, or analysis of other water quality or quantity
				  characteristics.
