Section 1 - 158 + 00 - 151 + 50 <br /> 650 foot segment from upper mine bench to ditch outfall RD-6 at <br /> switchback. No significant erosion or stability problems noted. Cut <br /> slope well vegetated. RD-6 outfall in good condition. 14 foot road <br /> width. No need for water bars here . <br /> Section 2 - 151 + 50 - 137 + 00 <br /> 1 ,350 foot segment from ditch RD-6 outfall at first switchback to <br /> Culvert C-7 at second switchback, adiacent to lower bin pad. Road width <br /> averages 12 feet. Preferred reclamation of this segment would be <br /> complete backfilling to eliminate road bed. Cuts along this segment <br /> mostly in shale or sandstone outcrop , or weathered shale with high <br /> percentage cobbles . Low potential for successful revegetation. <br /> Culvert Z-7 conveys flow to road segment below switchback. It would be <br /> preferable to discharge flow from road system at this point. It would <br /> appear to be possible to eliminate culvert and as an alternative <br /> construct a riprapped ditch from second switchback to sediment basin at <br /> base of mine bench outslope , thereby reducing volume of flow conveyed to <br /> discharge RD-5 at third switchback. If road discharge can be <br /> accomplished as suggested , no need for any water bars in Section 2 . <br /> Section 3 - 137 + 00 - 122 + 00 <br /> 1 ,500 foot segment from second switchback to RD-5 discharge at third <br /> switchback. Past erosion problems at RD-5 outfall , but channel <br /> relatively stable below. Proposed discharge at second switchback should <br /> help. Cut slope mostly in unweathered shale outcrop and weathered shale <br /> - little vegetation. First 500 feet, fill slope less than 75%, well <br /> vegetated; remaining distance to RD-5 outlet, fill is very steep and <br /> poorly vegetated. <br /> Section 4 - 122 + 00 - 113 + 00 <br /> 900 foot segment from RD-5 outlet at third switchback to Culvert C-6. <br /> Rd) width approximately 31 feet. Width reduction would probably involve <br /> combination of moving inside ditch in and reducing or "rounding" slope at <br /> crest of fill . Excavated material from fill crest reduction and ditch <br /> excavation would be backfilled against cut at moderate slope. Excavation <br /> areas and backfill areas would both be seeded and mulched. This would be <br /> a fairly typical reclamation/reduction scenario. <br /> _a_ <br />
