task will be made only for the unit price shown under Item 9 of the Bid Schedule. <br /> Payment shall be as this task is completed and approved by the PROJECT <br /> MANAGER. <br /> TASK 10 TOPSOIL APPLICATION <br /> Topsoil will be applied to most of the areas disturbed during completion of this Project. Areas to <br /> be topsoiled include the Upper and Lower Sutey access roads, the Ditch 8 area, the coal refuse <br /> pile located at the former location of the wash plant, the Old Coal Stockpile area located near the <br /> second switchback of Road A, and all other areas affected during Task 9, Earth Work. <br /> NOTE that topsoil application at the Upper and Lower Sutey access roads was accomplished <br /> during completion of Task 4, Road Grading. Topsoil application specifications for these two <br /> areas are contained in this Task description, and payment will also be made under this Task. <br /> Topsoil application of the area adjacent to Ditch 8 which was covered by the liner was <br /> accomplished during completion of Task 8, Surface Channels, and was paid per that Task <br /> description. Topsoil application of areas outside of the liner will be described, measured and <br /> paid under Task 10, Topsoil Application. <br /> Upon completion and PROJECT MANAGER approval of Task 9, Earth Work, and any <br /> other tasks which must be accomplished prior to topsoil application, topsoil will be <br /> applied to the various features subject to this Project. Topsoil will be derived from the <br /> topsoil stockpile located immediately west of the Sutey Topsoil Stockpile (Map 3, <br /> Project Area). <br /> Prior to topsoil application, all areas to which topsoil will be applied will be ripped. The <br /> ground surface will be ripped to a minimum depth of eight inches (8") on no less than thirty inch <br /> (30") centers. Ripping shall occur perpendicular to the fall of the slope. Topsoil will be spread <br /> to a depth of six inches (6") over all areas subject to this Project, unless otherwise <br /> specified in another Task. It is estimated that Xxx acres will be topsoiled. Therefore, <br /> approximately 00000 cubic yards of topsoil will be needed to achieve an average six <br /> inch (6") cover of soil over all areas. Upon completion of the topsoil application, the <br /> surface of the soil shall be left in a roughened condition. <br /> Coal Refuse Pile Roughening <br /> CONTRACTOR will create a minimum of thirty five (35) small bumps or hummocks per <br /> acre on the slopes of the coal refuse area. These features will be constructed in a <br /> random pattern across the slope. A two foot (2') minimum overlap of the edges of the <br /> hummocks is required (see Figure 3, Soil Hummocks). These bumps or hummocks will <br /> be the width of a dozer blade, eight to ten feet (8' to 10') in width, by six to eight inches <br /> (6" to 8") in height. The axis of these features vyill be constructed perpendicular to the <br /> fall of the slope. The top of the refuse disposal area will be roughened as described <br /> below. <br /> Roughening of Other Areas <br /> 19 <br />
