• <br />n. <br />road will be constructed at an approximately 2H:1 V slope. As required by Rule 4.03.1(31(e1, <br />the fill should be constructed on stripped foundation surface. Since the ground surface at this <br />site is steeper than 3:1, a 10-foot keyway is required. The fill should utilize material obtained <br />from other road-cuts at the site. It should be clean of organic matter, and contain no coal- <br />' related material. Compaction should ba a minimum of 95 percent Standard Proctor <br />compaction (D-698, or AASHTO T•99) in maximum 12-inch lifts. Large particles that inhibit <br />proper lih development or compaction should be removed. Roads-cut in unconsolidated <br />material, as may be the case for some parts of the haul road, shouk! bs constructed at 2H:1 V <br />when possible. A vegetative cover should be placed immediately to stabilize fills and cut <br />slopes. Until fills and Cut copes can be stabilrsed using vegetation, oNer means such as a silt <br />fence may be used to control sediment. ' <br />The initial haul road on the east side of the coal mine waste bank is located in an area that <br />cannot be routed to the sediment pond. That is, runoff wlleasd in the ditch can not be <br />routed to the sediment pond due to topographic constraints. A small area exemption from the <br />sediment control requirements is needed from the Division of Minerals and Geology, and best <br />management practices (BMP) should be used. For example, sih fences and revegetation will <br />be used to capttxe sediment. Maintenance should be performed regularly to remove collected <br />sediment. Flows should be routed as necessary away from the road. <br />Haul roads will be surfaced with a minimum of six inches of crushed, durable rock material. <br />Surfaces will be graded to drain into adjacent drainage ditches, and will be maintained to avoid <br />ponding of water. <br />Haul roads will be reclaimed after their use for mining operations. All culverts wiA be removed, <br />and natural drainage pattsms will bs restored. Cut and fill locations wip bs recontoured to <br />match the surtounding topography. The road bed witl be ripped and scarified as necessary <br />before the recontoured cut and fill slopes are revsgetated. Tertaess or other means will be <br />constructed to prevent excessive erosion. t <br /> <br />96266/112~.RPT CoU Mlrr W~~u Bank O~ripn far tfr s~nbom GrHk Mir <br />Oetotrr1996 WESTEC,Iro. 9 <br />
