south side of the operation has a mean grade of about 2.8:1. That is not a bad slope as evidenced by the <br /> fact that it is quite stable and vegetated. It is not in any great danger of failing, and has survived some <br /> very wet periods over its 33 year life. That said,the top 10'to 12' of the total berm is not compacted and <br /> very porous. Although leaving the entire berm as is, except for the eroded eastern end, would likely be <br /> safe considering how long it has been there, it will be recommended that some work be done to lessen <br /> the slope on the south side of the berm. <br /> The last part of the berm on the west side of the pit is basically just a wing extension aligned <br /> along a south to north line connected to the south berm that runs east/west. This portion is also in good <br /> condition, although the west slope is a bit too steep. However, once again, the berm has been there a <br /> very long time and has never exhibited any significant problems.This berm is quite secure and seems <br /> fairly well compacted. <br /> 2. Exposed Cut Slopes and Faces: In contrast to the good condition of the South Berm are the <br /> faces of the other boundaries of the pit. Those are definitely in need of work. <br /> In the process of mining the sand, cut faces (sometimes called highwalls) were created around <br /> the edge of the mined area. Their height is a function of the difference in elevation from the original <br /> land surface and whatever depth the mining extended. These are primarily exposed on the east side of <br /> the operation which was the working face that was being expanded eastward in a strip mine style of <br /> mining. But there are other faces exposed on the north and northwest and beneath the <br /> overburden/soil/visual berms. There is a small exposure of a working face on the eastern end of the <br /> south berm that is now severely eroded. Fill similar to what is in the rest of the south berm, as described <br /> before, is piled in mounds on top of the exposed and eroding cut faces on the bed that was being mined. <br /> It is probable that this part of the South Berm was never configured like the rest of the South Berm. <br /> These cut faces are easily reclaimed by grading and sloping of the eastern faces followed by <br /> "topsoiling" with overburden/topsoil. Measurements show the current grade of these slopes is close to <br /> 2.5:1 along the entire eastern face. So creating 3:1 slopes would only require extending the toe of these <br /> slopes T to 15'to the west. That should be easily accomplished, once a lot of the deep rilling and <br /> "almost gullies"in some places are reduced to some extent. A little roughness in the pre-topsoiling <br /> surface is quite useful in achieving a bond between the growth medium and the native material. <br /> The northern exposed faces can be fixed during and after removal of the overburden/soil <br /> stockpile. Partially using a cut and fill sloping on the faces followed by covering with the growth medium <br /> ("topsoil"). In many cases, if the berm material is not completely removed, simply reshaping the berm <br /> Vollmer Pit Technical Revision June 2018 Updated Reclamation Plan Page 5 of 26 <br />
