Fill material for the north end of the pit - July 2, 2021 <br /> 1A. . z. _ <br /> ,w <br /> _gib _•- . ., _„� ,, _;,�-•- � � _ - <br /> a <br /> _ <br /> J <br /> > j <br /> .. r <br /> Here is a view of the material on the west side of the basin next to the drainage outlet at the north end of the pit. Obviously, this is not <br /> consistent with the reclamation plan. To partially elevate the floor of the basin to the left, this material will be pushed into that basin to <br /> achieve an elevation such that water flowing from the south end (visible in the distance) can smoothly and gradually exit the pit. Thus, <br /> these slopes will become a bit steeper (5:1) but they will smoothly grade into the bottom of the pit. With this and the intensive grading <br /> on the south end of the pit, the whole area will become a gently rolling and shallow valley compatible with the character of the <br /> surrounding topography. <br /> In the far distance is the intense green area below the low highwall at the southern edge of the pit. That will all become a gentle slope <br /> (5:1). To the right of this area is an elevated mound. That is the topsoil that was removed from the area mined. In the final step this soil <br /> will be returned to the entire regraded pit to provide a growth medium for the revegetation. <br />
