Raced A <br />Road A will be goaded to n_semble Its original (operatierra!) condRfon. Light grading will occur so that <br />water IS shed to the inside drainage ditch, kept in the area of the coal atockpr7ea. The ditett will bC <br />Ueaned of debris following the end of construction activiGe;. Inlets to existing culvert, wpl Ue dean_d of <br />sediment and debds, K any, at the compeGOn of construction activities. A Ilght appficaiion of dean three <br />quarter inch grave! will be applied to the Road A surfarr near Coal Stockpile B, whero reclamation <br />activities have narrnvred the roadway. <br />TASK 8 LOW WATER CROSSINGS <br />Two lowwater avssings will be 6uik on Road A. <br />One low water anssing will be ConsUVCted just west of Coal Stockpile 8, near the terminus of the <br />ovenand cameyor. The second low water crossing wUl )x consfruded ai the second sHtchbeck on Road <br />A near the ad Coal Storage bratiori. <br />E9dt anssing wiu be needy perpendirnrlafto rho length of the road, end will tsave a feu of about flue <br />percent across the ants. ingress and egress routes Will be about SH:1 V. The crossing wlD be the width of <br />the mad above ehd below the crossing. Outage rock wUl be placed within eadt erossJng, including tyre <br />base and side slopes. <br />TASK 4 SURFACE CHANNELS <br />Two surface channels will ire kxinstnrdat; one at the Uld Caat Storage Araa, and orte on the Rock Dump. <br />Ofd Coal Storage Area <br />r4rs approximately one hundred filly feet tong drainage d'dch will be wnstruded from the noQttem po+rtlan <br />of the Old Coat Storage Area, south across Road A, and down the inside portion of Road A to the pond <br />located outside of the fast Road A switchback. <br />The ditch will be triangular in shape. The ducts will have a depth of about eighteen Inches'at its center, <br />Side slopes will be 3H:tY or gerrtler. The ditch will have a gradient of about four peceerst, except where i! <br />is located acfyaceni to Read A beldw the low wafer crossing, where its gradient will match iisat of Road A. <br />A tow water crossing wrhi rte oonstnrded al the Raced A uossing of this ditch kt order that traffic may gull <br />access the upper portions rNthis road (508 Tank 3). <br />Rodk pump Channel <br />An approximately three hundred end fifty feet long drainage channel will be eottstruded on the Rodk <br />Dump in order to comrey runoff from the top and north side of the faplily to the Wlge Swale on the south <br />side of the pile. <br />The channel will be trapezoidal in shape, having a two feet bottom width and side slopes of about 31-L•1 V. <br />The rttihimum depth of the channel wi0 be two feet. <br />TASK 5 EARTH WDRK <br />coal RefrJSe Disposal Area <br />Ths Cosl Refuse Area w1t1 be covered b)r about twelve inches of eaNten mateAat. Thi9 material wilt be <br />generated pY reducing the hill side behind (south ot) the refuse pile from near vertical l0 2H:1 V. Defiat <br />material, 'd any, wiU be tla~led from the Sutey Topsal Stockpile. Tne shape of fire covere6 refuse wtp be <br />essentially the same as that of fhe erdsting material. The slopes of the disposal site have been <br />constructed to the desired slope angles. Therefore, earthen material placement will not result in <br />steepening of the slopes. <br />
