2.05.3 <br />Before drainage from the road is allowed to flow into any defined channel it is <br />passed though some form of alternative sediment control. This alternative <br />sediment control may include straw bales, riprap, check dams, mulches, <br />vegetative sediment filter, dugout ponds silt fences or other measures that <br />reduce overland flow velocity, reduce run-off volume and trap sediment. <br />The combination of gravel surfacing, dust control, sediment control on the <br />majority of the road and utilization of alternative sediment control on the <br />remainder of the road will assure that erosion, siltation, pollution of air or <br />water, and damage to public property will be controlled. These controls will <br />also assure that no damage to fish and wildlife or other related environmental <br />values will occur. <br />This road is the main access to the mine facilities so employees, contractors, <br />vendors, supply vehicles and visitors will utilize a portion of this road. The <br />truck traffic which will utilize this haul road segment will be 10 and 18 wheel <br />trucks. This road has two 12 -foot lanes. <br />Haul Road #1 has an average grade of 4.5% with a maximum grade of 10% <br />and a maximum pitch grade of 11.1 %. There is no more than 300 feet of <br />pitch grade exceeding 10 percent within any consecutive 1,000 feet on the <br />road. The Portal Haul road is located on the most stable available slopes to <br />minimize erosion. <br />Haul Road #1 is a pre-existing road. <br />2) Haul Road #2 to Coal Mine Waste Pile <br />General Requirements <br />This haul road is used to haul coal refuse to the coal mine waste pile. The <br />haul road is approximately 65 feet long. Haul trucks will cycle between the <br />portal level and the coal mine waste pile. Dust control on this road segment <br />includes gravel surfacing and watering to maintain surface moisture. <br />Sediment control will be utilized to assure that erosion, siltation, pollution of <br />air or water, and damage to public property will be controlled. The use of <br />dust suppression and alternative sediment control will assure that no <br />damage to fish and wildlife or other related environmental values will occur. <br />PR -02 2.05-13- 10/12 <br />
