z: <br />• sediment control measures will be utilized to decrease sediment to levels below effluent limitations, <br />incompliance with applicable State and Federal Laws and current interpretations of the regulations. <br />This will result in an increase of scouring in the channels below the sediment control measures as <br />the water reaches an equilibrium with natural sediment loading. Salinity will temporarily increase <br />due to exposure to the disturbed surfaces and newly weathered materials, particularly shales, and due <br />to evaporation from the ponds. Elevated salinity levels will be seen in runoff traversing any <br />disturbed area; i.e., facilities areas or the surface mine, and in spring discharges below the surface <br />mine. It is not possible to precisely predict the salinity levels, but the geochemistry of the <br />overburden and the water quality ofthe coal wells suggest a range of salinity levels which might be <br />expected from the discharge. The maximum conductivity was 2690 umhos, and it averaged 994 <br />umhos. Total dissolved solids values were only available from the water quality samples, and the <br />maximum value was 747 mg/1 from four coal wells, and averaged 709 mg/1. <br />• <br /> <br />ass-ve~~„itrov(Nov.a.oz).wpa 2.05-101 (Revised 10/31/02) <br />
