While-vc avating the north facing Slope behind the coal refuse disposal rile,a small volume of concrete <br /> rubble which is in place at ttks Ioe:itlon wal be remove-d to the conciv}e rubble disposal site, and WiD ha <br /> disposed of as described in Task 1. <br /> Old Coal Storage Area <br /> The goal of accomplishing earth work at the Old Coat Storage Area Is to dispose of remnant coal <br /> materials, and to create a drainage pattern consiztent with surrounding land forms. <br /> All Coal materials tooated In this area will be pushed to the bsec of the slope located to the west of this <br /> area. The coal will be piaced at a uniform depth across the length of the slope. <br /> A large catch bench e3dsts approximately forty feet above the base of the east facing slope. This bench <br /> WI be cut and pushed down to cover the coal placed at the base of the slope. It is desirable to cover the <br /> coal with at least one foot of this material. <br /> A drainage ditch is located an the north facing slope, north of,and below,the Old Coal Storage Area. <br /> This ditch will be eliminated by pulling in the outside edge to fill the ditch. <br /> A drainage divide wIU be created across the Old Coal Storage Area,trending east to west. The crest of <br /> the divide will coincide with the top of the excavation area created during excavation activities on the <br /> slope south of the Coal Refuse Disposal Area. Machinery will grade the land south of the drainage crest, <br /> and north of Road A,so that this area slopes toward Road A and the ditch created during Taste 4_ <br /> Area West Of Coal Refuse Pile <br /> This area is located against and adjacent to the north facing slopes south of the Fill Pond and west of <br /> Pond 024. Grading of this area will occur in outer that exposed coal is covered to a minimum of about <br /> twelve inches,and so that rain fall and snow melt rurwif flow in a northerly direction.toward Coal Creek. <br /> Area North of Coal Refuse Pile <br /> This area will be graded so that a slight gradient to the north Is created,causing rain fail and snow melt to <br /> drain as sheet flow north toward Coal Creels. Some.cut of the upper most portion of the bank above Coal <br /> Creek may be necessary to achieve the required fall. <br /> AA areas to be topsailed will be ripped during execution of Task 5 to promote soil adhesion. Ripping shall <br /> occur perpendicular to the fall of the slope at any one location. <br /> TASK 6 TOPSOIL APPLICATION <br /> After ripping is complete,topsoil will be spread to a depth of six inches(6)the following areas: <br /> Location <br /> Belt Line Transfer Road <br /> Area West Of Coal Refuse Pile <br /> Area North Of Coat Refuse Pile - <br /> Old Coal Stockpile Area <br /> Coal Refuse Pile <br /> Slope South Of Wash Plant <br /> Surface Roughening <br /> Roughening of the surface will occur after topsoil is applied, Differing degrees of roughening will be <br /> applied to various work areas. <br /> The BO Line Transfer Road,the east facing slope located immediately west of the Otd Coal Storage area <br /> and the north facing slope behind (South ot)the Wash plant area will be severely roughened following <br /> topsoil application. in order to accomplish the dcgrce of scwrity of roughening neco� ry.the following <br /> wilt be eccompllshed: <br /> 3 <br />
