These issues are as follows: <br />i. The main haul road to the mine site, which is referred to as Storm King Road, <br />acts as a drainage conveyance structure through the barrow ditches but, in no <br />way, is related to any sediment control. All drainage above culvert C2 <br />- - identified on the NCEC preliminary mine grading plan is diverted to sediment <br />pond A. <br />2. According to the original design drawings, the maximum grade for the haul <br />road, referred to as Storm King Road, is 8°,'0. Based upon information provided <br />to us. the roads were built according to the design drawings. <br />3. According to the original design drawings, the cut and fill slcpes for the main <br />haul road, or Storm King Road, are 1.75:1. Based upon information provided <br />to us, the roads were built according to design drawings. <br />4. The haul road subgrade was constructed according to accepted design <br />standards. The subgrade was scarified and compacted to 95% of maximum <br />density. The subgrade consisted of Class 4 pit run material. The subgrade was <br />overlain with Class 6 road base. It is our opinion that the entrance road has an <br />adequate service life far the loads that will he encountered. <br />If you have any questions or comments, please do not hesitate to call. <br />Sincerely, <br />SCHMUESER GORDON MEYER, INC. <br />"~~ <br />'~ ~ C,^ <br />•~ ;' _ <br />~S ~ l ~-'~ <br />Louis Meyer, P.E. <br />LM:Ic/901 58-Oa.3 <br />1572 Grand Avenue, Suite 212 • Glenwood Springs, Colorado 81601 • (303) 9a5.100s <br />
