INSPECTION REPORT - PAGE 4 <br /> FILE NO. 77-378 <br /> DATE: July 10, �985 <br /> 11 . As previously mentioned, mine water treatment pond sludge has been <br /> disposed in the settling pond near the Engineering office. This pond is <br /> not permitted for disposal of this sludge. The pond is located in the <br /> flood plain of the Animas River. In addition, it is unclear if this <br /> pond is adequately lined or sealed to protect alluvial groundwater. <br /> This sludge disposal site is not permitted in the Mined Land Reclamation <br /> Division Permit. There is concern for high water possible washing out <br /> this area. This was discussed in the field. See Recommendation No. 5. <br /> Terry Tunnel/Lake Emma Site <br /> 12. This site was discussed and no field inspection was made. The site was <br /> inaccessible because of unmelted snow on the access road, Mr. Murray <br /> stated that it should be accessible in early August. Mr. Murray stated <br /> that he believed that the Terry Tunnel site had been previously <br /> permitted. He also stated that underground mining in this area <br /> dewatered Lake Emma after a major cave-in occurred in stopes mined below <br /> and close to the Lake Bottom. This lake area which is apparently now a <br /> glory-hole has not been addressed in terms of reclamation or mining in <br /> the permit document. It was discussed that a mining and reclamation <br /> plan should be submitted for this area. It was discussed that this may <br /> be considered off-site damage to areas outside of the permitted affected <br /> lands. The Division will attempt to inspect this site during late <br /> August. See Recommendation No. 5. <br /> 13. The Division appreciates the operator' s cooperation during this <br /> inspection. <br /> RECOMMENDATIONS: <br /> 1 . Investigate the feasibility and submit an adequate surface drainage <br /> control plan for the American Tunnel site. This should be submitted <br /> prior to August 16, 1985. <br /> 2. Take sample of the mine water treatment pond sludge and analyze for a <br /> complete suite of trace metals, sulfate, chloride or other possibly <br /> toxic elements or compounds which may be in the sludge. Samples should <br /> be sent to an EPA certified laboratory. Analyses from samples <br /> previously taken could be submitted. Submit this data prior to <br /> August 16 1985. <br />
