• 1.0 INTRODUCTION <br />The Bowie Mine No. 2 is a subsurface coal mine owned and operated by Bowie Resources, LLC <br />(Bowie). The Bowie Mine No. 2 is located on the north side of Colorado State Highway 133, <br />approximately 3.5 miles northeast of Paonia in Delta County, Colorado. The mine produces <br />approximately 3 to 5 million tons of coal per year. Coal waste from the preparation plant as <br />well as some high ash coal is disposed at a coal waste disposal area located north of Bowie <br />Road. Buckhorn Geotech, Inc. (BGI) was retained by Bowie to evaluate stability of the <br />proposed Coal Waste Disposal Area No. 4 (CDWA No. 4). BGI's initial stability evaluation is <br />documented by a 2007 report (BGI, 2007). The initial report evaluated stability for ultimate <br />heights up to 118 feet measured vertically from the toe of the refuse bank to the crest. This <br />report presents revised stability evaluations for an ultimate refuse height of 150 feet. <br />2.0 PROJECT BACKGROUND <br />The CWDA No. 4 is located immediately west of CWDA No. 2, immediately east of CWDA No. 1 <br />and north of Topsoil Pile "E ".
