Chemical Parameter Justifications <br /> Chemical Parameter Justification <br /> pH a characteristic of water needed to assess the solubility <br /> ranges of the chemical parameters; a characteristic of rock <br /> needed to assess acid-base forming potential; effluent <br /> limitations of Rule 4.05.2 (7). <br /> Electrical Conductivity an indicator of the general quality of water; an indicator <br /> of the salinity hazard associated rock materials. <br /> Total Combustible Solids an indicator of the fire hazard potential of underground <br /> mine refuse rock and coal processing wastes. <br /> Lithologic Classification an indicator of general rock texture and type. <br /> Textural Analysis an indicator of textural variability; needed to <br /> % sand assess erosiveness and suitability of rock <br /> % silt material to be used as a plant growth medium; <br /> % clay an indicator of the infiltration and water retention <br /> properties of spoils material. <br /> Saturation Percentage an indicator of the general plant growth medium potential <br /> of rock materials; an indicator of the water holding <br /> capacity, expected percolation rate, and clay swelling <br /> capacity of rock materials; used to evaluate the accuracy of <br /> reported SAR values. <br /> Sodium Adsorption Ratio (SAR) an indicator of the irrigation potential of water; an indicator <br /> of the dispersing character of the clay fraction of rock <br /> materials; an indicator of the infiltration capacity of rock <br /> materials. <br /> Major Ions• <br /> Calcium (Ca+2) a predominant cation in mine drainage at the Edna <br /> Mine, concentration increased above background <br /> levels (Skogerboe, et al., 1979); concentrations may <br /> increase in waters near surface mines in the western <br /> U.S. (Everett, 1979); needed to evaluate ion balances; <br /> needed to calculate SAR. <br /> Magnesium (Mg+2) a predominant cation in mine drainage at the Edna <br /> Mine, concentration increased above background <br /> levels (Skogerboe, et al., 1979); concentrations may <br /> increase in waters near surface mines in the western <br /> U.S. (Everett, 1979); needed to evaluate ion balances; <br /> needed to calculate SAR. <br /> GCC Energy, LLC King 11 Appendix 4(8A) (PR-10) June 12, 2020 <br />
