BOWIE RESOURCES, LLC <br />Bowie No. 2 Mine <br />New Coal Mine Waste Bank Inspection - 2°d Quarter 2005 <br />On seven separate occasions, I performed visual inspections of the Bowie No. 2 Mine <br />coal mine waste bank in accordance with Rule 4.10.2. The final inspection occurred on <br />June 29, 2005. <br />I, J. E. Stover, P.E., have a wide variety of experience in the design and construction of <br />earth fill embankments. Nothing was observed during the inspections that would <br />indicate the pile has a potential for failure. The gob disposal area was dry during the <br />final inspection. All organic material and topsoil has been removed ahead of the waste <br />bank founding. The upper diversion ditch was inspected with no problems noted. <br />The slope inclination of the second lift has been flattened to 5H:1 V. The operator is <br />making good progress in flattening the first lift to 2.5H:1 V. The elevation of the top of <br />the pile is approximately at the level of the second bench. The large rock drain was <br />extended in the west drainage during the quarter. Pictures area attached, <br />Most of the coal mine waste was generated from the preparation plant. Approximately <br />135,000 tons of gob were hauled to the gob pile. Coal mine waste is to be placed in the <br />pile in approximately horizontal lifts no more than 24-inches thick. The coal mine waste <br />is spread and compactive effort is provided by a self propelled sheepsfoot compactors. <br />Compaction tests were performed throughout the quarter. A total of 46 tests were <br />taken on the pile. Five tests failed. Two of the tests that failed passed upon retest. <br />Three of the tests that failed will be retested during the third quarter. A test passes if <br />the test attains at least 90% of the maximum dry density attained in a laboratory <br />compaction test in accordance with ASTM D698. Relative compaction test results are <br />enclosed. <br />A failure of the pile would probably not be a hazard to human life. A residential dwelling <br />is located over 300-feet below the pile. The pile is located above SH-1336. A failure of <br />the pile might damage the state highway but would not likely impact the residential <br />dwelling. <br />I certify that to the best of my knowledge and belief, that the fill and other aspects of the <br />new coal mine waste bank have been constructed as permitted <br />by the DMG. <br />
