SENT BY: 1-21-97 ; 12:58 0 S M- 1 303 2410336;* 6/13 <br /> base are perforated, flow udder the base of the flume may cause <br /> saturation of portions of the Old Refuse Pile, resulting in its failure <br /> into the adjacent Coal Creek. Dependant upon stream flow at the time <br /> of failure, the refuse material will either by washed downstream into <br /> the Crystal River, or a blockage of Coal Creek will occur. <br /> The end foundation has experienced some degree of undercutting, and <br /> could experience a failure. The failure will most likely result in the <br /> forty five feet tall foundation falling either up- or down stream. The <br /> obvious safety concern aside, the result of the failure will be erosion <br /> and possible failure of adjacent portions of the Old Refuse Pile. <br /> Personnel within the office of surface Mining have designed a stream <br /> channel diversion for Dutch Creek. This design utilizes accepted <br /> geomorphic principles in routing Dutch Creek through the facilities <br /> area to a logical confluence point with Coal Greek. Colorado proposes <br /> to implement this design to overcome the environmental and health and <br /> safety issues presented by the current Dutch Creek alignment. The <br /> estimated cost to accomplish this project is $175,000. <br />
