Pineda <br />Director <br />The Colorado Division of Reclamation, Mining and Safety (the Division) has received <br />the Colowyo Coal Company, LLC's (Colowyo) submittal of Technical Revision 86 - <br />South Taylor Haul Road As-Built. The revision was submitted on 23 June 2010 <br />(received on 24 June 2010) and deemed complete on 6 July 2010. The Division has <br />reviewed the submittal and has the following preliminary adequacy questions. <br />1. On Map 25C, there are two polyp-shaped extensions shown at the north and south <br />ends of the South Taylor Haul Road. The Division assumes that these two <br />features are runaway truck ramps. No stationing or profile data has been <br />submitted for these extensions. Please provide labels, horizontal stationing and <br />centerline profiles for the polyp-shaped features illustrated on Map 25C. <br />2. The third paragraph of the Construction Report (Page P-1) states that topsoil was <br />"salvaged and stockpiled directly to the west of the haul road footprint prior to <br />commencement of haul road construction." The locations of the topsoil stockpiles <br />are not shown on Map 25C. Please revise Map 25C to identify the sizes and <br />locations various topsoil stockpiles developed prior to construction of the <br />South Taylor Haul Road. If the topsoil was placed in an existing topsoil <br />stockpile(s) please include the information on Map 25C and in the <br />construction report. <br />Map 25C provides plan and profile views of the as-built South Taylor Haul Road. <br />Included on the plan is a Typical Haul Road Cross Section. While haul road cross <br />sections are not specifically required by the Rules, the Division requests that <br />Colowyo provide a series of cross sections for the as-built South Taylor Haul <br />Road, created perpendicular to the centerline of the roadway, at 500-ft <br />intervals. <br />Office of Office of <br />Mined Land Reclamation Denver • Grand Junction • Durango Active and Inactive Mines
