ORIGINAL-PUBLIC FILE <br />Page 2) <br />MINE ID # OR PROSPECTING ID #: ti+-IOan_~ad <br />INSPECTION DATE: R/6 Lt~8/4/n7 INSPECTOROS INITIALS: ~~ <br />OBSERVATIONS <br />The Division conducted a monitoring inspection the site in response to a phone call from <br />Mr. Gary Goodrich Manager Environmental Affairs, regarding the Phase IVC low volume <br />solution transducers reading above the allowable two feet of head. As the MLRD Board <br />approved amendment requires, CC&V is to contact the Division when the head exceeds in a <br />sustained manner, which was the case when DRMS was contacted. <br />According to Gary at 1:05 P.M, on 6/5/07, during the routine inspection that the mine <br />conducts every 4 hours, the operator noted the spike in head and notified management. <br />CC&V mobilized the repair crew to determine if there was a failure in the pumps. <br />Even though both pumps were operating the amount of mumping rate was less than the <br />capacity of the pumps. At that time the low volume readings were well in excess of 80 <br />inches. <br />To aid the existing pumps, two diesel operated booster pumps were added to existing pumps. <br />The Division arrived on site at 3:OOp.m and with Mr. Goodrich present drove to the Phase <br />IVC Low Volume solution collection transducer read out area. <br />At that time the two booster pumps and one of the original pumps were operating. The # 2 <br />pump, 2 inch diameter pipe was being replaced for better function. According to Mark <br />Vanoni of CC&V, who was monitoring the pumping capacity at that time, the pumps were <br />operating at 45-50 gpm. <br />Low Volume transducer read out # 1 was at 89.7 & #2 was at 84.7 inches of hydrostatic <br />head. High Volume Transducer # 7 was at 44.5 #8 was at 45.3 # 9 was at 44.7 and the pipe <br />or # 10 was at 44.7. <br />Mr.Denne Deemer, the process manger explained the actions taken by the mine and the <br />efforts to determine if the usual rain storms the area had received contributed to the <br />cause. A brief discussion regarding how to prevent from such incidents from repeating <br />themselves were discussed. No matter what the cause, both the Division and CC&V IS A9PRE <br />THAT repeated incidents such ae theses that are extended in duration can not happen. <br />Similar incident took place in late 2004. At that time the pumping capacity was doubled <br />and the problem appeared to have been solved. <br />On 8/7/06 with Gary Goodrich, Mark Vanoni and Demmer present, the following readings were <br />collected from the Phase IVC Low and High Volume collection transducers. Low volume <br />transducer # 1 was at 84.7 and # 2 was at 78.2 inches of hydrostatic head. Both pumps and <br />booster ware actively pumping at the time of the inspection. High Volume transducer #7 was <br />at 44.0 8 was at 44.7 #9 was at 47.1 and # 10 was at 44.7. <br />7Phile in the area looked at the new additional carbon columns located along the south side <br />of the ADR building, according to Denni, the columns should be operational by the end of <br />the week. <br />Inspected the Phase 2, II & III, leach pads and collected the following readings from the <br />High and Low volume solution collection transducers. <br />Phase 2 High Volume solution collection transducer # 1 was still not functioning, # 2 was <br />at51.2#3 was at 53.0. Low volume # 1 was at .39 and # 2 was at.39. Pieaomtar for the pond <br />was at 56.5 <br />Phase II AND iii High Volume Solution Collection transducer # 4 was recorded at 38.0 # 2 <br />was at 38.1 and # 3 was at 39.4. Low volume was at .19 and .36. <br />Inspected the under drains, both the 4 inch pipe and south under drain were discharging. <br />All lower ponds were dump. Dissipation pond was holding some water. No problem noted. <br />
