Colorado ~ 21 <br />~303~ 858-].396 <br />April 4, 1984 <br />Mr. Jim Herron <br />Reclamation Specialist <br />Colorado Mined Land Reclamation <br />1313 Sherman Street, Room 423 <br />Denver, Colorado 80203 <br />RE: Annual Water Report <br />McClane Canyon Mine C-004-80 <br />Munger Canyon Mine C-020-81 <br />Dear Jim: <br />iii iiiiiiiiiiiiiiii <br />999 <br />r/, ~: tr <br />APR ~ ~ 1984 <br />~.71vED LAf;D „ICI."°'.'~+1C~>~ tl{"~:;40t1 <br />Cola. O~ai. c. ,:a.wa~ ,..~uurces <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 />Tab 1e 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 continue to discharge water throughout <br />next year and has been in compliance with NPDES discharge re- <br />quirements in the past. Average and maximum values are shown <br />in the table below for the parameters analyzed during the last <br />year. <br />PARAMETER AVERAGE MAXIMUM <br />PH 8.38 su 8.68 su <br />Total Suspended Solids 2.27 mg/1 8.0 mg/1 <br />Iron, Total 0.14 mg/1 0.19 mg/1 <br />Oil and Grease, Visual 0 0 <br />Total Disolved Solids 1517 mg/1 1696 mg/1 <br />Flow 7988 gpd 30030 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 />
