2-27iii <br />approximately horizontal lifts no more than 24-inches thick, and such lifts <br />made uniformly over long stretches. Each lift will be moistened or dried to a <br />uniform moisture content suitable for maximum compaction. Compaction will <br />be carried to the edge of the fills so that the final slopes are firm. The pile <br />shall be graded in a matter to avoid runoff over the face of the pile and/or <br />ponding of water, and interim ditches, if required, will be constructed <br />according to final ditch specifications. If standing water develops after the <br />pile has been over-excavated and before coal waste has been placed in the <br />pile, the water will be pumped into the sediment pond. <br />Compaction tests will be taken at a frequency and location of not less than <br />one per every other layer, at random locations across the pile. Test locations <br />and results will be reported to the Division in the appropriate construction <br />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 <br />construction of earth and rockfill embankments under the direction of a <br />qualified professional engineer, on a quarterly basis, beginning within 7 days <br />after the preparation of the disposal area begins. In addition the area will be <br />inspected during the following critical periods: removal of all organic material <br />and topsoil, placement of underdrain system, if an underdrain is required, <br />installation of surface drainage systems, placement and compaction of fill <br />materials, and during revegetation. Inspections shall include such <br />observations and tests as may be necessary to evaluate the potential hazard <br />to human life and property, to ensure that all organic material and topsoil <br />have been removed and that proper construction and maintenance are <br />occurring in accordance with the approved plan. A report will be provided to <br />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 />The certified report addressing the underdrain system and protective filters, if <br />an underdrain is required, will include color photographs taken during and <br />after construction, but before underdrains are covered with excess spoil. If the <br />underdrain system is constructed in phases, each phase shall be certified <br />separately. The color photographs accompanying each certified report will be <br />taken in adequate size and number with enough terrain or other physical <br />features of the site shown to provide a relative scale to the photographs <br />TR-16 Mc-Volume I 10/08 <br />
