Nitrate-Nitrite a major component of ammonium-nitrate explosives <br /> commonly used at surface mines in the western U.S.; an <br /> indicator of spoils material suitability as a plant growth <br /> medium; a common constituent of fertilizers spread on <br /> reclaimed areas. <br /> Sodium (Na+) a predominant cation in mine drainage at the Edna <br /> Mine, concentration increased above background <br /> levels (McWhorter, et al., 1975); 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 /> Sulfur an indicator of the acid-base forming potential <br /> % Pyritic Sulfur of spoils or refuse rock: % pyritic sulfur is <br /> % Sulfate Sulfur an indicator of acid-forming potential; <br /> % Organic Sulfur % sulfate sulfur is an indicator of <br /> Total Sulfur base-forming potential; % organic sulfur is an indicator of <br /> the potential for spontaneous combustion of a mine's <br /> refuse pile. <br /> Trace Elements <br /> Arsenic (As) concentration reported to increase in mine spoils water <br /> at the Edna Mine (Skogerboe, et al., 1979); <br /> concentrations may increase in waters near surface <br /> mines in the western U.S. (Everett, 1979); likely to have <br /> a higher than average concentration in coal and <br /> associated shales (NAS, 1977); may be a pollutant <br /> associated with fly ash disposal in surface mines in the <br /> western U.S. (Everett, 1979) <br /> Boron (B) an indicator of the usefulness of spoils and refuse rock as a <br /> plant growth medium (Bingham, 1973); concentrations may <br /> increase in waters near surface mines in the western U.S. <br /> (Everett, 1979). <br /> Cadmium (Cd) concentrations may increase in waters near surface mines <br /> in the western U.S. (Everett, 1979); may be a pollutant <br /> associated with fly ash disposal in surface mines in the <br /> western U.S. (Everett, 1979). <br /> Copper (Cu) concentrations may increase in waters near surface mines <br /> in the western U.S, (Everett, 1979); may be a pollutant <br /> associated with fly ash disposal in surface mines in the <br /> western U.S. (Everett, 1979); change in Cu:Mo ratio could <br /> cause molybdenosis in livestock. <br /> Iron (Fe) increased concentration reported in mine spoils water at the <br /> Edna Mine (Skogerboe, et al., 1979); concentrations may <br /> increase in waters near surface mines in the western U.S. <br /> (Everett, 1979); effluent limitations from Rule 4.05.2 (7). <br /> GCC Energy, LLC King 11 Appendix 4(8A) (PR-10) June 12, 2020 <br />
