break from essentially level ground(original land surface) and the slope. If the slope is unsuitable for <br /> direct planting(e.g. very gravelly as could happen near the bottom of the slope)then a fresh layer of <br /> soil/overburden will be placed on top of that area. If a complete 3:1 slope cannot be created, then the <br /> rest will be created using overburden as backfill. In most places,cut and fill should be able to create <br /> the entire slope,but on the east side next to the powerlines some backfill may be needed. <br /> It is important in creating the 3:1 slope that the surface of the soil NOT be smoothed. The <br /> surface should be left fairly rough so vertical rills and gullies will be less prone to be created by <br /> erosion on the slope. Furthermore, final creation of the slope should not be done until just before <br /> planting is expected to occur. If it will be some time between when the slope is created and when <br /> planting can occur it is best to delay the creation of the final slope so it can be followed, ideally,by <br /> planting within about 30 days after completion(the earlier the better). Furthermore,when the finished <br /> slope is created it should be left in a rough condition and not smoothed. Smoothing the slope is a <br /> common mistake and is a major factor in creating problematic eroded slopes. <br /> If the slope is created too soon and the surface is smoothed there is a high probability that <br /> heavy precipitation will erode the slope which will require working the surface again to remove any <br /> deep rills or gullies that form prior to seeding. That simply adds to the cost of preparing the ground for <br /> planting. As described later, final grading and seeding should ideally be done as a single operation. <br /> But how rough is rough enough?First,there should be no equipment tracks, especially rubber <br /> tired vehicles but also bulldozers,that run up and down the slope as that simply provides a path for <br /> water to flow. Instead, equipment tracks should follow the contour so ridges are created that act as <br /> little dams. Most equipment can easily traverse a 3:1 slope along the contour if the soil is dry. <br /> How high should the ridges be? That is difficult to say because there is no way to know how <br /> much precipitation, if any, will occur before planting occurs. It is risky no matter what,but a couple of <br /> inches is best if planting can occur in 30 days-the longer this period the higher the ridges up to about <br /> 3 inches. It also depends on the amount of rain expected or actually happens. A seed drill will usually <br /> have discs and compacting wheels that can prepare and finish the fine texture of the slope <br /> immediately after the planting is completed, all in one operation. <br /> PIT BOTTOM: As areas of the floor or bottom of the pit no longer need to be used for <br /> conducting the mining, Soil/Overburden acquired from stripping prior to mining will be spread to a <br /> Fountain Pit Technical Revision#3 - June 2022 M-1982-155 Reclamation Plan Page 11 of 23 <br />
