Current Practice <br /> Current construction of the pile follows Geo-Hydro's recommendations. There is a <br /> distinction made between the final slopes, which have been built at 2(H):1(V) and <br /> compacted, as opposed to the temporary slopes, where on-going activity makes such <br /> construction procedures impractical. <br /> The direction of construction of the pile is generally south, toward the upslope of the <br /> hillside. The final slopes extend along the north side, paralleled by the drainage ditch. <br /> In construction of the pile, Mid-Continent agrees that temporary slopes should be <br /> constructed so as to prevent ponding on the pile. Future placement of refuse, and <br /> subsequent grading, will allow for drainage toward the south side, then down to the <br /> pond(s). Drainage conveyances for the temporary slopes of the pile will be, <br /> themselves, temporary so as to be sized and routed <br /> Mid-Continent notes that drainage from the temporary slopes has not been previously <br /> dealt with as a permitting matter. Recommendations for a 2:1 slope, with compaction, <br /> were made as a consideration for stability of the final slopes, and do not properly apply <br /> to the temporary slopes. <br /> 3 <br />
