rolling the coal mine waste with a front end loader or water truck. A self propelled soil <br />compactor may be used such as a Cat 815 or 825. Alternatively a pull behind sheepsfoot <br />roller may be utilized. Any equipment that can compact the coal mine waste and achieve <br />the compaction specification may be utilized. The placing and spreading of the coal mine <br />waste will be started at the lowest point of the foundation. The coal mine waste will be <br />keyed into the natural ground. Materials will be spread in approximately horizontal lifts <br />no more than 24- inches thick, and such lifts made uniformly over long stretches. Each lift <br />will be moistened or dried to a uniform moisture content suitable for maximum <br />compaction. Compaction will be carried to the edge of the fills so that the final slopes are <br />firm. The pile shall be graded in a matter to avoid runoff over the face of the pile and /or <br />ponding of water. <br />Compaction tests will be taken at a frequency and location of not less than one per <br />every other layer, at random locations across the pile. Test locations and results will be <br />reported to the Division in the appropriate construction reports. <br />The coal mine waste pile area will be inspected for stability by a qualified <br />registered engineer or other qualified professional specialist experienced in construction <br />of earth and rockfill embankments under the direction of a qualified professional engineer <br />on a quarterly basis. Inspections shall include such observations and tests as may be <br />necessary to evaluate the potential hazard to human life and property, to ensure that all <br />organic material and topsoil have been removed and that proper construction and <br />maintenance are occurring in accordance with the approved plan. A report will be <br />provided to the Division by the inspecting engineer within two weeks of the completed <br />inspections. A copy of this report will be kept at the mine site. <br />MR -97 2.05 -27i Revised 09/28/11 <br />
