MINE ID # OR PROSPECTING ID#: M-1977-493 PAGE: 5 <br />INSPECTION DATE: 9-8-03 INSPECTOR'S INITIALS: ACS <br />A reclaimed road above and along the south shore of Eagle Park Reservoir <br />was inspected. This road was previously inspected and described in the <br />report of the DMG's 9-17-98 inspection. The backfilling and grading of the <br />road were done to reflect the appearance of the surrounding undisturbed <br />land. Vegetation is becoming established on the reclaimed areas, and no <br />weeds were observed. <br />The Eagle Park Dam seep EPF was inspected. Although the conversion of <br />Eagle Park Reservoir to a fresh water reservoir is complete and the water <br />impounded in and released from the reservoir is of very high quality, <br />seepage from the downstream toe of the dam continues to carry 10-15 mg/L <br />iron and 15-17 mg/L manganese. As a result, the seepage water must be <br />collected and pumped up to Warren's Pump Station for the foreseeable <br />future. The Eagle Park seep EPF has previously been discussed in the <br />reports of DMG inspections dated 9-28-93 and 7-2-98. The EPF consists of <br />primary and secondary seep collection ponds keyed into bedrock, the Eagle <br />Park pump house and pipeline, and a back-up generator that was installed <br />during 1999 in preparation for Y2K and the potential for power disruptions. <br />This EPF also has a checklist and bar code as discussed above. It was <br />observed that all facilities are being maintained and operated to <br />effectively prevent any 5-Dam seepage from entering the East Fork of the <br />Eagle River. <br />A new EPF called Ron's Riser was inspected. Ron's Riser was installed to <br />perform a fairly simple function, which is to decant water from Ten Mile <br />Pond and drop it through a large diameter borehole into Ten Mile Tunnel. <br />However, the engineering of this facility was complicated by the large <br />capacity that has to be carried in the borehole and the large vertical drop <br />from the pond to the tunnel. The riser was designed so that water swirls <br />into the inlet preventing air pocket formation that could backpressure the <br />borehole. Since Ron's Riser is an EPF, the design and construction <br />information and engineer's certification required for EPFs must be <br />submitted to DMG. <br />Dust control measures on exposed tailing surfaces were inspected. Climax <br />has essentially discontinued the use of coherex for dust control and now <br />uses a weak cement and wood fiber mixture that is applied with a <br />hydromulcher. Use of this product on an active tailing pond would not be <br />feasible, but for the inactive ponds at Climax the effectiveness, <br />durability, and relatively low cost make it ideal. Annual re-application <br />rates for dust control have dropped to about 50 acres per year due to the <br />durability of the cement crust that is formed. <br />The lime plant EPF was inspected. Anew back-up generator set has been <br />installed at the lime station. Both Arkansas River water stored in <br />Buffehr's Lake as well as McNulty Well water are used to slake the lime. <br />The water level in the McNulty Well is monitored continuously and a minimum <br />allowable water level in the well has been established to prevent <br />contaminated water from being drawn into the well's capture zone. All <br />critical functions of the lime plant are instrumented, and Climax maintains <br />
