0 2.05.3 <br />5) Haul Road to Lower Gob Pile <br />General Requirements <br />This road segment is approximately 500 feet long. Reference Map 16, Haul Road Plan & <br />Profile - Gob Pile. This road provides access from the south side of Bowie Road to the <br />lower gob pile. Drainage from this road is contained in sediment pond J. <br />Gravel surfacing and water to maintain surface moisture will provide dust control on this <br />road segment. This road segment will be plated with 6 to 12 inches of gravel. <br />The truck traffic which will utilize this haul road segment will be 10 wheel dump trucks. A <br />20 -foot wide, 2% center crowned, gravel surfaced road will be adequate for these haul <br />trucks. Vehicle traffic should have no problem with this road configuration. There are no <br />road segments that exceed 10% grade. <br />The gob haul trucks may track gob material onto Bowie Road and this road segment. The <br />operator will utilize a water truck to clean Bowie Road and this road segment as <br />necessary. The wash down water will be directed to the road ditches which will convey <br />the water to Ponds B and J. A skid steer loader will be used to clean up any small spills. <br />The bridge over the Fire Mountain Canal has solid steel plates on the running surface. <br />Solid steel plates are located on each side of the bridge. These plates will assure that no <br />gob material gets into the Fire Mountain Canal from trucks crossing the bridge. <br />Design and Construction <br />For the construction of this road segment, all vegetation material and topsoil will be <br />removed from the design road bed, shoulders, and surfaces where associated structures <br />will be placed. Topsoil will be placed in one of the topsoil stockpiles located on site. No <br />vegetation material or topsoil will be placed beneath or in any haul road embankment. <br />The embankment specification presented above applies to this road segment. <br />Acid- or toxic - forming substances will not be used in the haul road surfacing or <br />embankment. <br />Temporary erosion control measures will be implemented during the construction of the <br />haul road. Silt fences or other alternative sedimentation control devices will be placed <br />along the edge of the embankments. After construction is complete the area disturbed <br />will be seeded and mulched to reduce the rate and volume of run -off. <br />Drainage <br />The discussion of drainage presented above under the discussion of the main haul road <br />is applicable to this road segment. <br />Reclamation of this haul road will involve returning the road to its pre- mining contours. <br />The road will be returned to its relative flat configuration as shown on Map 18 Post Mining <br />Topography. <br />n <br />TR-49 2.05 - 24i - 09/07 <br />�) PPRoVED <br />61yl'o 1 <br />
