CENTRAL APPALACHIA 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 in accordance <br />with the approved plan and the applicable regulations. This yearly inspection is for the <br />impoundment located at the McClane Canyon Mine. <br />On December 22, 2005, I performed the required yearly inspection. I, J. E. Stover, <br />have a wide variety of experience in the design and construction of earth fill <br />embankments. Nothing was observed during the inspection that would indicate the <br />pond has a potential for failure. There was no appearance of erosion, instability,. <br />structural weakness or other hazardous conditions. There are no required monitoring <br />procedures or instrumentation other than monthly and yearly inspections. There are no <br />aspects which might affect stability and there is no required maintenance. The <br />sediment pond had water standing 2-feet above the primary spillway at approximate <br />elevation of 5459. Even though water/ice is standing above the level of the primary <br />spillway, there is still adequate capacity in the pond to contain the 10-year 24 hour <br />event. <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 in the permit. <br />The sediment pond has the following estimated capacity based on the existing water/ice <br />level in the pond: <br />POND CAPACITY -ACRE FEET <br />Water Sediment Total <br />(0.67 Max) (75% of 0.28) 0 <br />66 <br />0.45 0.21 . <br />To the best of my knowledge and belief, the <br />McClane Canyon Mine has been maintain@r <br />approved plan and applicable regulatiory4a`~ <br />James E.
