TASK 3 EARTH WORK �` n <br /> General Side Slope Excavation <br /> Upon completion of Task 3, Earth Work, the side slopes of each excavation shall be cut to 2.5 H <br /> : 1 V, as measured from the toe of each side of the excavation. In some instances (specifically, M <br /> ponds 018, 022, 001, 008, 021), the excavated earthen materials will be used to complete pond <br /> access road reclamation (see Task 5, Access Road Reclamation).Where the excavated C" �� } <br /> material is not specified for use in access road reclamation, it will be loaded into small end- <br /> dump trucks. The material will be trucked and dumped in area specified by the PROJECT <br /> MANAGER. This material will be utilized in the vicinity of the pond from which it was excavated, <br /> but never further than one half mile (2,640') from the pond from which it was excavated. In most <br /> instances, the material will be spread around the margins of the pond, above the high water ►^P' �! <br /> elevation. <br /> The material will be spread at each designated disposal location in single lifts no greater than <br /> six inches (6"), unless otherwise specified by the PROJECT MANAGER. The CONTRACTOR <br /> shall provide appropriate equipment to spread the material to the specified depth. <br /> An approximately two hundred cubic yard (200 yd3) topsoil stockpile is located at pond 018. <br /> This material wills be hauled west approximately one thousand two hundred feet (1,200') to the <br /> Mine 2 bin pad. The material will be evenly distributed throughout this approximately three <br /> quarter (3/4) of an acre area. Following topsoil application, the area will be severely <br /> roughened, as described below. <br /> The excavated embankment cut surface shall be severely roughened following completion of the <br /> earth work to the specifications using a trackhoe or similar piece of equent in the following <br /> manner: <br /> - Upon completion of excavation, two (2) tons of certified weed free mulch shall be <br /> applied to the cut surface. Mulch shall be provided by The CONTRACTOR, and shall <br /> conform to Section 20.2 of the Revegetation Specifications, attached. All mulch shall <br /> be certified as noxious weed free or noxious weed seed free by any authorized State or <br /> County Officer. Documentation of certification shall be provided to the PROJECT <br /> MANAGER prior to application of mulch. The mulch shall be evenly distributed over the <br /> cut surface. Surface roughening will occur simultaneously with distribution of the weed <br /> free mulch in order to prevent loss of the mulch due to wind. <br /> Scarify the surface by using a trackhoe bucket or similar piece of equipment to <br /> create numerous gouges in the cut slope. Gouge or pull the cut slope surface and <br /> J � 41 mulch toward the machine in a manner such that no less than twelve inches (12") of <br /> vertical relief is created. These gouges shall be sufficiently close so that no more <br /> than eighteen inches (18") exists between the crest of one gouge and the crest of an <br /> adjacent gouge, in any direction. <br /> Additional Pipe Removal and Earth Work <br /> Two pond systems have buried inlet or outlet pipes which must be excavated and removed from <br /> the site. <br /> 10 <br />
