F • ~ (Page 2) MINE ID f OR PROSPECTING ID / N-94-117 INSPECTION DATE 5 7 96 INSPECTOR'S INITIALS ACS The i.netallation of the land application system for water collected and pumped up from the Haze].-A adit was inspected. Four parallel pipelines with three sprinkler heads on each line have been installed in the area above the tailing pond. Plumbing in the mill building ie provided that will allow pumping of Hazel-A water into the land application system directly from the Hazel-A pump, or, alternatively, from the steady head tanks located at the northeast cornEer of the mill building. The land application system was charged momentarily so that the function of the sprinklers could be observed, and it was observed that the eyetem operated as intended. The steady head tanks are fouled with sediment, and need to be flushed-out prior to utilization in the land application system. The operator has been using water pumped up from the liazel-A ad it to flush the tanks for the last several weeks, with the slurry from the flushing operation being discharged to the pond. Flushing of the steady head tanks needs to continue to be the priority use of Hazel-A water until such time that the tanks are completely cleaned. Once the tanks are clean, the operator may contact the Division for authorization to land apply Hazel-A water in order to facilitate drying-up of the tailing pond.. The spray evaporation eyetem in the tailing pond was inspected. The two spray evaporation lines are now charged by separate pumps, and a total of 80 spray heads have been installed. One eipray head was missing, with water shooting out directly from the manifold into the pond. Rich:srd Fox stated that this spray head would be re-installed by the afternoon of the day of the inspection. The pipe stands used to support the spray evaporation lines are generally too i:limey to support the weight, and should be bolstered with hay bales or otherwise. All other aspects of the spray evaporation eyetem were operating ae intended. Colorado Lining Company was on site at the time of this inspection to repair pond liner damage that occurred as a result of traffic on the liner during installation and operation of the spray evaporation eyetem. Several of the new liner repairs were inspected and found to bfa acceptable. The operator intends to recover some gold values from concentrates that were accidently diecliarged to the tailing pond at some time during past milling operations. The Division has no problems with the reprocessing of materials from the pond ae long as containment of tailings and process water is adequately assured. To that end, the operator has installed the required curbing in the mill building at all man-doors and overhead-doors. This curbing was inspected and found acceptable. Also, during operations to recover concentrates from the pond„ no new solids, liquids, or chemicals may be introduced. The operator may not process or discharge tailings that are currently stored in the large thickener tank, and may not process the ore that is stored in the ore bins. cc: Carl Mount, DMG Richard Fanyo Dufford and Brown, P.C. 1700 Broadway, Suite 1700 Denver, CO 80290 Earl K.
