apt A <br /> Road A will be graded to resemble its original(operational)condition. Light grading will occur so that <br /> water Is shed to the inside drainage ditch,except in the area of the coal stockpiles. The ditch wifl be <br /> cleaned of debrL-following the end of construction activities_ Inlets to existing culverts vw4 tie cleared of <br /> sediment and debris, if any,at the completion of construction activities. A light application of dean three <br /> quarter inch gravel will be applied to the Road A surface near Coal Stockpile B,where reclamation <br /> sctivifies have narrowed the roadway. <br /> TASK 3 . LOW WATER CROSSINGS <br /> Two low water crossings will be built on Road A <br /> One low water crossing will be constructed just west of Coat Stockpile E. near the terminus of lire <br /> oveAand conveyor. The second low water crossing will be constructed at the 2econd switchback on Road <br /> A near the Old Coal Storage location. <br /> Each crossing will be nearly petpendioAarto the length of the road,and will have a fail of aootfi We <br /> percent across the axis. ingress and egress routes will be about SH:1 V. The crossing will be the width of <br /> the road above and below the crossing. Durable rock will be placed within each crossing,including the <br /> base and side slopes. <br /> TASK 4 SURFACE CHANNELS <br /> Two surface channels will be construed;one at the Old Coal Storage Area, and one on the Rack Dump. <br /> Old Coal Storage Area <br /> An apprwArnzteiy one hundred fifty feet long drainage ditch will be constructed from the northern portion <br /> of the Old Coal Storage Area,south across Road A, and down the inside portion of Road A to the pond <br /> located outside of the first Road A switchback. <br /> The ditch will be triangular in shape. The ditch wilt have a depth of about eighteen inches at its center. <br /> Side slopes will be 3H.1V or gentler. The ditch will have a gradient of about four percent,except where it <br /> is located adtacent to Road A below the low water crossing,where its gradient will match that of Road A. <br /> A kry water crossing wM be constricted at the Road A crossing of this ditch In order that traffic may stilt <br /> access the upper portions of this road (see Task 3). <br /> Rock Dump Channel <br /> An approximately three hundred and fifty feet long drainage channel will be constructed on the Rock <br /> Dump in order to convey runoff from the top and north side of the facility to the large Swale on the south <br /> side of the pike. <br /> The channel will be trapezoidal in shape,having a two 15cet bottom width and side slopes of about 3H_4V. <br /> The minimum depth of the channel will be two feet. -- <br /> TASK 5 EARTH WORK <br /> Coal Refuse Disposal Area <br /> The Coal Refuse Area will be covered by about twelve inches of earthen material. This material will be <br /> generated by reducing the hill side behind (south of)the refuse pile from near vertical to 2H:1V. Deficit <br /> material, if any,wifl be hauled from the Sutey Topsoil Stockpile. The shape of the covered refuse will be <br /> essentially the same as that of the existing 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 /> 2 <br />
