Seepage was noted at the base of gob pile number 4 during the quarter. A french drain <br />was installed to covey the seepage away from the toe of the pile. The french drain was <br />dry during the inspection. There was no seepage noted that would cause a concern <br />regarding slope stability. The attached June 21, 2103 Buckhorn Geotech summary of <br />instrumentation monitoring report addresses wet areas near the toes of the slope and at <br />the intersection with haul roads that cross the slope. <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 />I certify that to the best of my knowledge and belief, #b&QI and other aspects of the <br />coal mine waste banks have been constructed design approved by <br />the DRMS. ���.••� l•'. <br />41* O�L <br />4t 3 <br />E.
