MINESITE INSPECTION NARRATIVE 8 <br /> located on or near the old refuse pile, the Sutey <br /> refuse pile, and at the warehouse. Field parameters <br /> are again taken for depth, temperature, Ph and <br /> conductivity. Grab samples for lab analysis are done <br /> for it different parameters. After looking at the <br /> monitoring records, it was noted that Mercury was not <br /> being tested for by the lab from 1988 to the present. <br /> DMG was questioned if the mine plan been modified in <br /> regard to the missing parameter. Initially there was <br /> no comment but we later determined that it had been <br /> dropped from the list of parameters per a mine plan <br /> approval. <br /> Monthly weather data is also gathered for the mine <br /> from a station located near the mine's old district <br /> office. <br /> An effort was made by Mr. Berry to do some field <br /> analysis tests for Ph and conductivity of the mine <br /> water discharge below the rock tunnel pile sediment <br /> control system. It was noted that the flow occurring <br /> during the inspection was running between 275 to 280 <br /> gallons per minute. from the discharge point below the <br /> rock tunnel pile seiment control system. Point #016, <br /> the 6 inch flume below the outfall showed a level of <br /> .43 . Ph recordings below the outfall showed 8. 9, with <br /> a conductivity of 2, 380 umhos at 71 degrees F. A side <br /> drainage flowing across the toe of the pile through a <br /> diversion showed a pH of 8.2 . The inflow measurement <br /> near the top of the rock dump indicated a Ph of 8.93. <br /> The comment was made that the minor change in ph <br /> probably was influenced by the outflows occurring in <br /> the pile and from contact with the rock tunnel <br /> deposits. <br /> Bio-monitoring result records of the mine discharge <br /> indicate that the salt levels from mine water <br /> discharges are too high for survival of cerodaphnia. <br /> Testing is under way by the operator to determine <br /> exactly what is cause of the failure. Apparently <br /> there is no requirement by the Colorado Dept of Health <br /> to cease discharge or to treat flows, to prevent <br /> biomonitoring failure. Follow-up is underway by <br /> OSM\AFO to determine if further action is needed in <br /> this area. <br /> The disturbed area water discharges from the rock <br /> tunnel dump ponds (also mine water) , the Sutey pile <br /> ponds and the processing plant/main mine area were <br /> noted during the inspection. The discharges appeared <br /> to be meeting suspended solid limitations; there were <br />
