Dept of Natural Resources <br />Denver, Colorado 80203 <br />RE: Carbon Junction Ptine - Temporary Haul Road Certification <br />Dear Mr. Squire: <br />1 I am a professional Engineer registered in the states of Colorado, <br />New Mexico, and Idaho. My experience in the design and <br />construction of haul roads associated with surface coal mines <br />began in 1972 where I was responsible for such work at a major <br />coal mine complex in Ohio. I continued to be active in this <br />area for a major engineering and construction firm and completed <br />work on projects located in New Mexico, Wyoming, Montana, Texas, <br />)1 and Colorado during the period from 1975 1978. Since 1978 <br />I have been responsible for the design and implementation of <br />I the mining operations and their support facilities under the <br />New Mexico regulatory program for Sunbelt Mining Company, Inc. <br />Under contract to Pueblo Coal, Inc., I personally inspected the <br />temporary haul road leading to the Carbon Junction Mine on <br />September 18 and November 28, 1984. In addition, an engineer <br />under my direction monitored progress throughout construction. <br />The purpose of this inspection and monitoring was to ensure that <br />construction was in compliance with the design entitled Pueblo <br />Coal, Inc. Response to Step 2, N.O.V. C-84-078 dated July 2, <br />1984. This design was submitted to MLRD and approved by letter <br />dated August 8, 1984 from MLRD. The approval had one stipulation <br />that the cut slopes on the road be no greater than 1v:5h or a <br />static safety factor of 1.5 be demonstrated on steeper slopes. <br />During my inspections I noted that the required seven additional <br />culverts had been installed and one existing culvert had been <br />1 relocated for drainage control. Minor revisions to their specific <br />locations as shown in the design were necessary to meet field <br />conditions, however, area drainage planning was unchanged. All <br />culvert sizes were as specified in the design. <br />I <br />
