Three entries are driven <br />on the strike. <br />Chemical Parameters <br />The chemical parameters of the Harvey Gap Outlet above the mine and below <br />the mine fall within the ranges established in 1984-1987. Technical Revision <br /># 4 decreased the surface water quality monitoring to semi-annual monitoring. <br />The mine water discharge parameter results <br />similar. This would be expected due to the <br />the entries. <br />for 1987 and 1988 are quite <br />small overall advancement of <br />Flow and Field Parameters <br />The flow and field parameters of the Harvey Gap Outlet continue to demonstrate <br />the seasonal discharges from the Harvey Gap Reservoir. No significant <br />deviations from the 1984-1987 data are noted. <br />The underground wells continued to show a decrease in flow and pressure. <br />Technical Revision # 3 discontinued monitoring of the wells. <br />Impacts on Surface and Ground Water <br />No discharge has occurred from the sediment pond SP-.1. <br />The hydrology monitoring data are listed 'on the attached tables: Flow <br />and Field Parameters, and Chemical Parameters. A comparison of 1988 <br />data with 1984-1987 data indicates that there are no impacts on ground <br />or surface water due to mining. <br />
