Page 2 ace Stabilization In order to determine the rate of weathering on the exposed bedrock, CMLRD requested that additional laboratory testing be conducted. Swell consolidation tests were conducted, and the test results have been incorporated into the report. The results indicate a swell between 3% and 6%. To minimize erosion on the slope above the road and on the pond slope, runoff must be kept to a minimum. It was suggested that a diversion ditch be constructed above the road cut. Normally, this would be a viable method to prevent runoff from traveling across the exposed bedrock slope, but in this case, the ditch would be of little benefit. Currently, a topsoil stockpile, catchment basin and road exist above the road cut. The road to the stockpile acts as a diversion ditch, routing water to either the catchment basin or proposed culvert F3. If a diversion ditch were constructed, it would only collect less than one acre of runoff area. In order to minimize the amount of runoff traversing the pond side slope (exposed bedrock) a berm ditch will be created above the slope. Positive flow in the ditch will be maintained to the west at approximately 5% grade. The toe of the slope will be subject to, wave action and water table fluctuations. To minimize detrimental effects and reinforce the toe, rock will be placed at the toe of the side slope excavation. Should the above methods prove insufficient in retarding erosion, Peabody will initiate other erosion control methods, subject to prior approval by the Division. Material Removal and Disoosal The slide material will be removed with dozers and scrapers. Dozers will cut the slope face down and the material will be picked up by scrapers at the toe of the pond side slope. Material will be picked up in this manner until conditions become too wet to load the material with conventional equipment. Rock laterals will be constructed from seep areas encountered during excavation. It is estimated that between 15,000 cy and 20,000 cy of material will be moved during the excavation of slide materials and road realignment. Once the slide material has been removed, the slope face will be rocked as noted above, at the contact between the face and the water line. The rock will extend above and below the principal spillway elevation. Excavated material will be temporarily stored in the waste stockpiles to the east of Pond 006. These stockpiles will be seeded to minimize erosion. The final disposition of these piles will be haulage to a final open pit.
