• ~ECENE~ APR p g 2001 BOWIE RESOURCES LIMITED Bowie No. 1 Mine DivisionotM'~ne~alsa~8p1ogY Reclaimed Coal Mine Waste Bank Inspection - 15' Quarter 2001 On March 21, 2001, I performed a quarterly visual inspection of the Bowie No. 1 Mine reclaimed coal mine waste bank in accordance with Rule 4.10.2. I, J. E. Stover, P.E., have a wide variety of experience in the design and construction of earth fill embankments. Nothing was observed during the inspection that would indicate the pile has a potential for failure. The pile and surrounding area were dry to damp. Drainage was adequate. No seeps or spoil springs were noted. The pile has been reclaimed. The pile blends in with the surrounding area so it is difficult to determine the areal extent of the reclaimed waste pile. Records indicate 15" to 24" of non-toxic material was placed over the coal mine waste. The reclaimed pile supports a good stand of vegetation however, the outslopes were partially denuded of vegetation by wildlife activity this spring. According to the permit, this waste pile was filled to capacity in August 1983 and reclaimed. In the spring of 1985, spontaneous combustion was detected. Topsoil and cover material were excavated and the hot spot was removed. The area was apparently reclaimed again during the Summer of 1988. The design of the waste disposal area is presented in Volume 6A. To the best of my knowledge and belief, based on my inspection of the pile and previous inspections by professional engineers, the coal mine waste bank has been constructed in accordance with the approved plan. According to previous inspections, the pile was constructed with 1.5H:1 V outslopes. The outslopes were stable. The pile is located in a remote area well away from human habitation. A failure of the pile might damage the sediment pond located below the pile. However, a failure of the pile would probably not be a hazard to human life. Recommend maintenance: None - Watc
