0 2.05.3 <br />construction project. Excess fill from the preparation plant site work was be <br />placed along this road segment. <br />Dust control on this road segment includes gravel surfacing and watering to <br />maintain surface moisture. <br />Alternative sediment control will be utilized to assure that erosion, siltation, <br />pollution of air or water, and damage to public property will be controlled. <br />The use of dust and alternative sediment control will assure that no damage <br />to fish and wildlife or other related environmental values will occur. <br />The truck traffic which will utilize this haul road segment will be 10 wheel haul <br />trucks and 35 to 50 ton haul trucks. Considering the light traffic anticipated, a <br />20 -foot wide road surface should be adequate for these haul trucks. Vehicle <br />traffic should have no problem with this road configuration. About 300 -feet of <br />segment one has an 11 % grade, from Stations 126+00 to 126+00. No other <br />area of either haul road segment exceeds 10% grade. <br />Design and Construction <br />For the construction of this road segment, all vegetation material and topsoil <br />. will be removed from the design road bed, shoulders, and surfaces where <br />associated structures will be placed. Topsoil will be placed in one of the <br />topsoil stockpiles located on site. No vegetation material or topsoil will be <br />placed beneath or in any haul road embankment. <br />The embankment specification presented above applies to this road <br />segment. <br />Drainage <br />The discussion of drainage presented above under the discussion of the <br />main haul road is applicable to this road segment except drainage from this <br />road segment does not pass through a sediment pond. Drainage from this <br />road segment will be routed off the road surface into collection ditches off of <br />both sides of the road. Before this drainage is allowed to flow into any <br />defined drainage it will be passed though some form of alternative sediment <br />control. This alternative sediment control may include straw dikes, riprap, <br />check dams, mulches, vegetative sediment filter, dugout ponds silt fences or <br />other measures that reduce overland flow velocity, reduce run-off volume or <br />trap sediment. <br />• PR -12 2.05-29- 02/10 <br />PP2oV6b <br />I I /14/1 b <br />
