' conditions also influenced the conductivity and TDS as exhibited in the graphs in <br />Appendix 1. <br />Analysis of trace metals indicates low concentrations. Aluminum and iron were detected <br />in all samplings, higher values being reported during high flow events (Appendix 1). <br />' Manganese and zinc were also sampled and found in only trace amounts. <br />Mining and reclamation operations at the Chimney Rock Mine appear to have little or <br />' no effect on the quantity or quality of area surface waters. This may be due to the mines <br />inactive status during 1985 through 1989. Backfill and grading activities occurred in the <br />Revision 1 Pit and Surface facilities during 1990 and 1991; however, sediment control ponds <br />' established on the disturbed areas eliminated runoff of surface waters from the mine site. <br />All NPDES forms were filed with the Department of Health during quarterly reporting <br />periods. CDMG also received copies of these reports. During 1992, no discharges were <br />reported from any of the ponds. Results of the annual pond survey are contained in <br />Appendix II. <br />1 <br />1 <br /> <br />1 <br />5 <br />
