D°;i. c. ,.~....~, ,....~r,.cs <br />As required by Munger and McClane Canyon Mine Permits, Salt <br />Creek has compiled water use records for the last year at its <br />mines. This report will provide those water use records along <br />with an analysis of impacts expected for the next year. Both <br />Munger and McClane Canyon Mines were idle last year and are <br />anticipated to remain idle next year. <br />McClane Canyon Mine began the year with water stored in the <br />mine in all four sumps. A total of 1,519,710 gallons of water <br />were pumped from the sumps for use or discharge as shown on <br />Table 1. Currently, there is water in the Main Sump, Sump 2, <br />and the Face Sump. At this time Salt Creek is not able to <br />identify the source of the water. The fault noted on Figure <br />1 may be the source of the water, as water level in the mine <br />seems to fluctuate in response to surface water runoff. The <br />fluctuation would indicate that surface water is infiltrating <br />to the coal seam and the fault is the most likely source. <br />Salt Creek intends to <br />next year and has been <br />quirements in the past <br />in the table below for <br />year. <br />PARAMETER <br />continue to discharge water throughout <br />in compliance with NPDES discharge re- <br />Average and maximum values are shown <br />the parameters analyzed during the last <br />PH <br />Total Suspended Solids <br />Iron, Total <br />Oil and Grease, Visual <br />Total Disolved Solids <br />Flow <br />AVERAGE MAXIMUM <br />8.38 su 8.68 su <br />2.27 mg/1 8.0 mg/1 <br />0.14 mg/1 0.19 mg/1 <br />0 0 <br />1517 mg/1 1696 mg/1 <br />7988 gpd 3003.0 gpd* <br />* Salt Creek's NPDES Permit was amended on January 28, 1984 <br />to allow unlimited flow from the mine since the quality <br />of water was excellent and no impact on the Colorado River <br />would occur. <br />
