East PIt <br />On September 13, 2000 we notified the CDMG of the need to address an additional topsoil variance for <br />an area in the East Pit where the contractor could not remove topsoil for safety reasons. Selected <br />hillslopes were too steep, with so much rock outcrop that the stripping dozer could not safely remove <br />the topsoil. Byron Walker came to inspect the site and provided the approval for the variance. See the <br />9/13/00 CDMG Inspection report for additional details. <br />The following pictures provide an overview of the area after stripping. The contractor used a trackhoe <br />to remove the topsoil and place it into small 30ton trucks for transport to the reclaimed area. The <br />contractor was instructed to reach up as high on both slopes to remove as much of the topsoil as <br />possible. The contractor also dug into the bottom of the draw until he reached bedrock materials. In <br />many areas, 5 - 8 feet of material was recovered. <br />Photo I -- View looking west up the draw with the lower limit feast) of the variance area to the left <br />(10/30/00). Note the narrow bottom of the draw with as much topsoil removed as possible. The area to <br />the right is also a variance area because of its south exposure, rock outcrops and negligible topsoil <br />resource. <br />
