CAM MINING, LLC <br />McLANE CANYON MINE <br />IMPOUNDMENT YEARLY INSPECTION <br />In accordance with Rule 4.05.9(14), all impoundments shall be inspected at least yearly <br />to determine if the impoundment has been maintained as designed. and rn accordance <br />with the approved plan and the applicable regulations. This yearly inspection is for the <br />impow~dment located at the McClane Canyon Mine. <br />On March 13. 2007, I performed the required yearly inspection. I, J. E. Stover, have a <br />wide variety of experience in the design and construction of earth fill embankments. <br />Nothing was observed during the inspection that would indicate the pond has a <br />potential far failure. There was no appearance of erosion, instability, structural <br />weakness or other hazardous conditions. There are no required monitoring procedures <br />or instrumentation other than monthly and yearly inspections. There are no aspects <br />which might affect stability and there is no required maintenance. The sediment pond <br />had water standing at the center line of the primary spillway at approximate elevation of <br />5457.25. <br />The required capacity of the sediment pond is 0.55 A-F. The required water capacity of <br />the sediment pond is 0.36 A-F and the required sediment capacity is 0.19 A-F (ref. PAP <br />Section 2.4.1 and Table 4.2-12). The actual size of the pond exceeds the required <br />capacities listed rn the permit. <br />The sediment pond has the following estimated capacity based on the existing water <br />level in the pond: <br />^~ . <br />POND CAPACITY -ACRE FEET <br />Water Sediment Total <br />(U.95 Max} (75°0 of 0.28) 0.85 <br />0.64 0.21 <br /> <br />To the best of my knowledge and belief, the +mpoundmentlsediment pond at the <br />McClane Canyon Mine has been maintarrlr3d as designed and in accordance with the <br />approved plan and applicable regulatio(~. .~' „~ <br />~, <br />James E.
