BOWIE RESOURCES, LLC <br />Bowie No. 1 Mine <br />Coal Mine Waste Bank Inspection - 1St Quarter 2008 <br />On April 4, 2008, I performed a quarterly visual inspection of the Bowie No. 1 Mine coal <br />mine waste bank in accordance with Rule 4.10.2. <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 inspection that would indicate <br />the pile has a potential for failure. The pile and surrounding areas were dry to damp. <br />No seepage or spoil springs were noted around the pile. There were no drainage <br />alterations and no new bench construction. No topsoil was salvaged during the quarter. <br />The bench area immediately north of the gob pile was excavated to a level below the <br />gob pile during the fourth quarter of 2007. Approximately 7,500 tons of coal mine waste <br />from the timber storage area were hauled to this area during the quarter. Coal mine <br />waste is to be placed in the pile in approximately horizontal lifts no more than 24-inches <br />thick. The coal mine waste is spread and compactive effort is provided by a self <br />propelled sheepsfoot compactor. Compaction tests were performed during the quarter. <br />A total of three compaction tests were taken on the pile on two separate occasions. All <br />of the tests passed. A test passes if the test attains at least 90% of the maximum dry <br />density attained in a laboratory compaction test in accordance with ASTM D698. <br />Relative compaction test results are enclosed. <br />The design of the waste disposal area is presented in Volume 6A. To the best of my <br />knowledge and belief, based on my inspection of the pile and previous inspections by <br />professional engineers, the coal mine waste bank has been constructed in accordance <br />with the approved plan. <br />The pile is located in a remote area well away from human habitation. A failure of the <br />pile might damage the mine haul road located below the ~pQe. However, a failure of the <br />pile would probably not be a hazard to human life. oo°~® G2~~~o0 <br />Recommend maintenance: None o c®o Q ~~ T~~o~o a <br />0 0~ u~'L-: o <br />fl~o 19230 ~g~o <br />0 <br />a~~ o_ ~G-~ 3-og a~ ~~~~ <br />James°E~., Sto~eri;~~~4a Date <br />P.
