I ~ 2.2.2.1 Waste Disposal Haul Road <br />A road is a surface right-of-way for purposes of travel by land vehicles in coal <br />exploration or surface coal mining and reclamation operations. A haul road is any road <br />used for the transportation of coal, spoil or coal mine waste. <br />Access to the waste disposal area is from Colorado State Highway 139 as shown on <br />Figure 2.2-7b. The existing road along the Munger Canyon floor was previously <br />improved by the Operator. Sub-base preparation included compaction of material in fl- <br />inch lifts. Pit run gravel and crushed gravel surfacing was applied to improve the road <br />surface. <br />Gravel surfacing on the road and the vegetation present on the road shoulders will <br />assure that erosion, siltation, pollution of air or water, and damage to public property will <br />be controlled. These controls will also assure that no damage to fish and wildlife or <br />other related environmental values will occur. <br />Typically the haul road to the gob pile will be 16 to 20 feet wide. The haul road is plated <br />• with pit run gravel surfacing. This road is secured with a locked gate where it crosses <br />over Salt Creek. Therefore, use is very limited. The truck traffic which will utilize this <br />haul road segment will be 10 wheel dump trucks and 18 wheel haul trucks. Truck traffic <br />will also be very limited and sporadic. Use of the waste disposal area will only occur <br />after the McLane Canyon mine has generated coal mine waste. Four truck loads per <br />hour is the anticipated maximum traffic volume. The haul trucks will only encounter an <br />occasional vehicle on the road. Considering the low volume and sporadic use of the <br />haul road, the width and surfacing of the haul road should be adequate for the intended <br />traffic. <br />The haul road is located in the valley floor to minimize erosion. There are no fords of <br />ephemera! stream channels. <br />The haul road begins at SH139 and ends at the east edge of the waste disposal area. <br />The road is approximately 6,300 feet long with an average grade of 2.3%. The <br />maximum pitch grade of the road is 3%. <br />r1 <br />LJ <br />M~ 2.2-7i 9/02 <br />
