of the Bench 1 and Mixed Topsoil placement on the Johnson property (Zone 6 & 7). <br />10.0 General Topsoil Handling & Placement Procedures After February 2008 <br />Topsoil will be replaced on the Morgan Property once the approved postmine topography (projected from <br />the top of the overburden) is achieved and when no additional overburden grading is anticipated. All <br />topsoil placement will be in the final location. Topsoil will not be placed while saturated. Topsoil shall be <br />replaced along the contour, whenever feasible, to minimize potential erosion and topsoil/spoil interface <br />slippage problems. This practice will be discontinued on steep slopes where the safety of the equipment <br />operator is in jeopardy. <br />10.1 Mitigation of Friable Rock Deposits <br />It has been noted by DRMS and WFC that occasional deposits of friable shale or claystone deposits are <br />encountered in the Bench 1 overburden during stripping. Since these rock types are undesirable in the <br />Bench 1 material that is placed below the topsoil and subsoil. <br />During the stripping of topsoil and Bench 1 material, if any areas of consolidated, but friable rock deposits <br />are encountered, WFC operators performing topsoil stripping will follow the following procedure: <br />1) If the deposits are less than one truck load in size, the shovel operator will load the rock into a haul <br />truck, and instruct the haul truck driver to place the rock material in the backfill area at least eight feet <br />below the topsoil layer. <br />2) If the deposits are greater than one truck load in size, the shovel operator will leave the rock deposit in <br />place. It will than be removed during overburden stripping and placed in the backfill area at least eight feet <br />below the topsoil layer. <br />Rock deposits identified during stripping are buried immediately. However, during the placement of Bench <br />1 that has been stockpiled, further rocks may be identified. These are separated and buried the same as <br />during stripping, but may be temporarily piled near the Bench 1 stockpile for efficient transport. All rock <br />deposits identified within the Bench 1 are separated from the Bench 1 and buried at least eight feet below <br />the topsoil layer. <br />August 2013 (PR -08) 2.05.4(2)(d)-15 <br />
