11 <br />10.0 General Topsoil Handling & Placement Procedures After February 2008 <br />Topsoil was replaced on the Morgan Property once the approved post mine topography <br />(projected from the top of the overburden) was achieved. All topsoil was placed in the final <br />location. Topsoil was not be placed while saturated. Topsoil was replaced along the contour, <br />whenever feasible, to minimize potential erosion and topsoil/spoil interface slippage problems. <br />This practice will be discontinued on steep slopes where the safety of the equipment operator is <br />in jeopardy. <br />10.1 Mitigation of Friable Rock Deposits <br />It has been noted by DRMS and observed that occasional deposits of friable shale or claystone <br />deposits are encountered in the Bench 1 overburden during stripping. Since these rock types are <br />undesirable in the Bench 1 material that is placed below the topsoil, the friable shale or claystone <br />was placed about eight feet below the final Bench 1 surface. <br />During the stripping of topsoil and Bench 1 material, if any areas of consolidated, but friable <br />rock deposits are encountered, ERMR operators performing topsoil stripping will follow the <br />following procedure: <br />1) If the deposits are less than one truck load in size, the shovel operator will load the rock into a <br />haul truck, and instruct the haul truck driver to place the rock material in the backfill area at least <br />eight feet below the topsoil layer. <br />2) If the deposits are greater than one truck load in size, the shovel operator will leave the rock <br />deposit in place. It will then be removed during overburden stripping and placed in the backfill <br />area at least eight feet below the topsoil layer. <br />Rock deposits identified during stripping are buried immediately. However, during the <br />placement of Bench 1 that has been stockpiled, further rocks may be identified. These are <br />separated and buried the same as during stripping, but may be temporarily piled near the Bench 1 <br />stockpile for efficient transport. All rock deposits identified within the Bench 1 are separated <br />from the Bench 1 and buried at least eight feet below the topsoil layer. <br />July 2018 (TR -84) 2.05.4(2)(d)-12 <br />
