ODESTAR ENERGY, INC <br />1~1ct-ANE CANYON MINE <br />IMPOUNDP~IENT YEARLY INSPE <br />In accordance with Rule 4.05.9(14), all impoundments shall be inspected at least yearly to <br />determine ii the impoundment has been maintained as designed, and in accordance with the <br />approved plan and the applicable regulations. This yearly inspection is for the impoundment <br />located at the McClane Canyon Mine. <br />On March 25, 2003, I performed the required yearly inspections. I, J. E. Stover, have a wide <br />variety of experience in the design and construction of earth fill embankments. Noth+ng was <br />observed during the inspection that would indicate the pond has a potential for failure. There <br />was no appearance of erosion, instab+lity, structural weakness or other hazardous Conditions. <br />Tt-ere are no required mordtoring prccedures or ins:run•art.:::on other than monthly and yearly <br />nspectlons. There are no aspects which might affect staudr,y and there is no required <br />ma+ntenance. The sediment pond had water stand+ng within 1.3-teat of the primary spillway a1 <br />approximate elevation of 5459.7. <br />The inside slopes of the sediment pond were flattened to approximately 2H:1 V during the first <br />quarter 2002. There has bean little to no change in the side slopes during the ensuing year. <br />There is evidence of sediment buildup during the year. It is not possible to determine the <br />amount of sediment in tho pond because of the water standing in the pond. The required <br />water capacity of the sediment pond is 0.54 A-F (ref, PAP Section 2.4.1). There is no specific <br />sediment capacity defined for the pond. Tho actual size of the pond exceeds the required <br />capacity listed in the permit. <br />The sediment pond has the following estimated capacity: <br />POND CAPACITY -ACRE FEET <br />Water Sediment Total <br />0.57 0.32 0.89 <br />To the best of my knowledge and belief, the impoundmenU'sediment pond at the McClane <br />Canyon M+~te has been maintained as designed and m accordance with the approved plan <br />and apFficable regulations. <br />'` <br />~ o•'-t ~ I <br />~~trles E.
