August 21, 2014 C- 1981 - 035 /King Coal Mine MLT <br />proposed) needs to be represented in the SEDCAD runs for King 11 and depicted properly on <br />Map 007A. <br />• GCC has made some progress on lining the channel that carries accumulated wash / dust <br />suppression water down the slope and away from the belt tower. <br />Ditches and culverts for King I are depicted and described in Appendix 11(1) of the permit <br />binder. We discovered during the inspection that an accumulation of sediment had washed <br />over and obstructed the drop inlet to Reach 7. The contractor was able to use his excavator <br />to locate and clear the protective screen (Photo 5), and the work was accomplished swiftly. <br />TOPSOIL — Rule 4.06 <br />Removal 4.06.2; Substitute Materials 4.06.4(4); Storage and Protection 4.06.3; Redistribution <br />4.06.4: <br />• The topsoil stockpiles at King 11 were well covered with vegetation; no erosion or loss of the <br />resource was observed. <br />At King I, relocation of the clean water diversion ditch was producing a significant volume <br />of loose material (shale and fractured sandstone) that may be appropriate for covering the <br />refuse pile (as described in Section 2.05.4 of the King I permit volume). With the <br />concurrence of the DRMS inspector, some of this material was being hauled to the fan bench <br />for temporary storage (Photo 6). <br />EXCESS SPOIL and DEVELOPMENT WASTE — Rule 4.09 <br />Placement; Drainage Control; Surface Stabilization: <br />At the King I refuse pile, a large excavator had been used earlier in the week to cut in a new <br />clean water diversion ditch well above the elevation of the existing ditch. Due to the large <br />bucket width, the ditch is trapezoidal in shape (Photo 7), and will have a greater capacity than <br />the triangular design configuration shown on Map King I -015. GCC checked the grade of <br />the ditch, and determined that the fall was 6.5 feet in 600 feet, approximately a 1% grade, as <br />approved on Map King I -014. <br />• A new segment of riprap -lined ditch had been constructed up the northern flank of the face of <br />the refuse pile (Photo 8) to intercept the new diversion ditch. A layer of filter fabric was <br />visible beneath the sandstone blocks that formed the surface of the ditch. <br />The same contractor was at work during the inspection excavating loose material from the <br />slope below the new ditch. A competent face will be exposed, against which coal mine waste <br />can be placed. Excavated material was loaded into an articulated rock truck for dumping into <br />a stockpile (Photo 9). <br />PROCESSING WASTE /COAL MINE WASTE PILES — Rule 4.10 and 4.11 <br />Drainage Control; Surface Stabilization; Placement: <br />Much of the coal mine waste that had been stored temporarily in the western portion of the <br />King I facility has been trucked to the top of the refuse pile. A quantity of coal mine waste is <br />still stored temporarily on the pad area at the toe of the refuse pile. <br />• GCC anticipates that the quantity of coal mine waste presently available will not be sufficient <br />to completely fill the area between the current compacted material and the side of the valley <br />that will result from relocation of the clean water ditch further up the slope (Photo 10).
