dozers and track hoes to assist in the drying process. During the inspection, gob was being <br />hauled out of the west drying area, and stacked in the drying area on top of gob pile #3. Gob <br />was then replaced into the west drying area and compacted. <br />During active mining conditions, it is necessary to stockpile gob material at gob pile #3 <br />during the winter months, then place and compact the stockpiled gob when weather allows. <br />Stockpiling of gob can commence November 15 and end April 15. Winter stockpiled <br />material will be re -handled and compacted by September 30. Beginning on October 1, the <br />Operator should be compacting all material concurrently, until conditions again require <br />stockpiling. The stockpiling dates listed above should be considered flexible and may <br />change slightly from year to year based on weather conditions. The gob material will be <br />stockpiled in rows generally running from northwest to southeast. The rows of gob will be <br />placed in a controlled manner and overlap will be minimized so there is space between rows <br />to allow for drainage to the southeast. Windrows were located on top of the pile and <br />contained gob that had been hauled out of the west drying area. <br />The available volume of coverfill material is sufficient to meet the requirements of Rule <br />4.10.4(5). No coverfill was used for blending or other uses during the quarter. <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 directly <br />below the pile. Additionally, the gob pile sediment pond is located below the pile. If the coal <br />mine waste bank failed, the material would very likely be contained on the bench below the <br />pile and or within the gob pile sediment pond. <br />A failure of gob pile no. 2 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. <br />A failure of the piles might damage Bowie Road and the Fire Mountain Canal 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 might <br />damage the rail track below the pile. <br />I certify that to the best of my knowledge and belief, gl other aspects of the coal <br />mine waste banks have been constructed as per t .E"I pproved by the DRMS. <br />Colorado Professional Engineer <br />Registration No. 43402 <br />y2 <br />Date <br />
