BOWIE RESOURCES, LLC <br />Bowie No. 2 Mine <br />Coal Mine Waste Bank Nos. 1, 2 & 4 Inspections -2nd Quarter 2008 <br />On July 3, 2008, 1 performed a visual inspection of the Bowie No. 2 Mine coal mine waste banks <br />in accordance with Rule 4.10.2. This inspection includes Gob Pile Nos. 1, 2 and 4. <br />I, J. E. Stover, P.E., have a wide variety of experience in the design and construction of earth fill <br />embankments. Nothing was observed during the inspections that would indicate the piles have <br />a potential for failure. The gob disposal areas were dry to damp. All organic material and topsoil <br />has been removed ahead of the waste bank foundings. The upper diversion ditches were <br />inspected with no problems noted. <br />A significant amount of the gob pile no. 2 was covered with three feet of cover and one foot of <br />topsoil during the 4th quarter 2006. Most of the first and second benches were covered. Cover <br />material from gob pile no. 4 is being stockpiled on the west side of pile no. 2. <br />Most of the coal mine waste was generated from the preparation plant. Approximately 20,725 <br />tons of gob were hauled to the gob piles. Coal mine waste is to be placed in the pile in <br />approximately horizontal lifts no more than 24-inches thick. The coal mine waste is spread and <br />compactive effort is provided by a self propelled sheepsfoot compactor. Compaction tests were <br />performed during the quarter. A total of ten compaction tests were taken on the piles on nine <br />separate occasions. One of the tests failed (212). The area where the test failed was reworked. <br />The reworked area was retested and passed on the same day. The two tests that failed on <br />March 19th were retested during the quarter and passed (202 & 203). A test passes if the test <br />attains at least 90% of the maximum dry density attained in a laboratory compaction test in <br />accordance with ASTM D698. Relative compaction test results are enclosed. <br />A failure of the gob pile no. 1 would probably not be a hazard to human life. The pile is located <br />above a large flat bench. The bench is approximately 80 to 150-feet wide directly below the pile. <br />Additionally, the gob pile sediment pond is located belowthe pile. If the coal mine waste bank <br />failed, the material would very likely be contained on the bench below the pile and or within the <br />gob pile sediment pond. <br />A failure of the gob piles no. 2 and 4 would probably not be a hazard to human life. A residential <br />dwelling is located over 300-feet below pile no. 2. The piles are located above Bowie Road. A <br />failure of the piles might damage Bowie Road but would not likely impact the residential dwelling. <br />©pooap°? <br />I certify that to the best of my knowledge and belief, that the fill and ot1°aej`l?ae coal <br />mine waste banks have been constructed as permitted in the desig ®%' 0 b?
