dumped material remained stable during the 4th quarter and do not show any signs of <br />instability. <br />The underdrain system was inspected numerous times by Tamme Bishop, P.E. The <br />underdrain system was constructed as permitted in the design approved by the DRMS. <br />Color photographs were taken during and after construction. The photographs are <br />included with this report. <br />A failure of the gob pile no. 1 would probably not be a hazard to human life. The pile is <br />located above a large flat bench. The bench is approximately 80 to 150 -feet wide <br />directly below the pile. Additionally, the gob pile sediment pond is located below the <br />pile. If the coal mine waste bank failed, the material would very likely be contained on <br />the bench below the pile and or within the 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 <br />residential dwelling is located over 300 -feet below pile no. 2. The piles are located <br />above Bowie Road. A failure of the piles might damage Bowie Road but would not <br />likely impact the residential dwelling. <br />A failure of gob pile no. 3 would not be a hazard to human life. A failure of the pile <br />might damage the rail track below the pile. <br />I certify that to the best of my knowledge and belief, that the fill ang# is of the <br />coal mine waste banks have been constructed as permitted in tt s <br />d by <br />the DRMS. ,�.° � <br />'�, <br />rQ s� <br />� <br />Y <br />James E.
