0 2.05.3 <br />The truck traffic which will utilize this haul road segment will be 10 wheel <br />dump trucks. A 20 -foot wide, 2% center crowned, gravel surfaced road will <br />be adequate for these haul trucks. Vehicle traffic should have no problem <br />with this road configuration. There are no road segments that exceed 10% <br />grade. <br />The gob haul trucks may track gob material onto Bowie Road and this road <br />segment. The operator will utilize a water truck to clean Bowie Road and this <br />road segment as necessary. The wash down water will be directed to the <br />road ditches which will convey the water to Ponds B and J. A skid steer <br />loader will be used to clean up any small spills. The bridge over the Fire <br />Mountain Canal has solid steel plates on the running surface. Solid steel <br />plates are located on each side of the bridge. These plates will assure that <br />no gob material gets into the Fire Mountain Canal from trucks crossing the <br />bridge. <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 />Acid- or toxic - forming substances will not be used in the haul road surfacing <br />or embankment. <br />Temporary erosion control measures will be implemented during the <br />construction of the haul road. Silt fences or other alternative sedimentation <br />control devices will be placed along the edge of the embankments. After <br />construction is complete the area disturbed will be seeded and mulched to <br />reduce the rate and volume of run -off. <br />Drainage <br />The discussion of drainage presented above under the discussion of the <br />main haul road is applicable to this road segment. <br />Reclamation of this haul road will involve returning the road to its pre- mining <br />contours. The road will be returned to its relative flat configuration as shown <br />on Map 18 Post Mining Topography. <br />PR -12 2.05-32- 02/10 <br />
