March 28, 2012 C- 1996 - 083 /Bowie No. 2 Mine BFB <br />free of debris. At the Terror Creek fan site, a berm was in place, the ground sloped toward the spillway and straw <br />bales and rocks were in place for the SAE (photo 4). <br />Pond B, C, D and F contained water, were not discharging and appeared to be functioning properly. Pond J was <br />dry and pond K contained water from a recent clean-out of the train load out conveyor belt tunnel. <br />Ditch D -1 on the east side of gob pile 2, was diverted to ditch D -F 15 which drains to Pond F. Upon further <br />review it has been determined that this change is not part of the Coal Mine Waste Disposal Area Drainage Plans <br />(Volume IX, Figure 2). Ditch D -F4 is designed to drain directly to Pond F and not to Ditch D -1 Ditch D -1 is <br />also not constructed to the designed specification outlined in Volume IX, page App -B 15 and Figure 3. It is <br />supposed to be a trapezoidal channel with a bottom width of 3.0 feet and side slopes of 1.5:1 (photo 5). <br />Continued review determined that Ditch D -F15 is also not constructed according to the Coal Mine Waste Disposal <br />Area Drainage Plans. According to the SEDCAD design (Volume IX, page App -1326) and Volume IX Figures 2 <br />and 3, ditch D -F15 is a trapezoidal riprap channel with a bottom width of 3.0 feet, side slopes of 1.5:1 and a 30% <br />slope from north of the coverfill stock pile to the southeast corner of the pile where ditch turns to the west. <br />Currently, Ditch D -F 15 is not riprapped and stops on the east side of the coverfill pile (photo 6). At this point, the <br />water is discharged at the top of a reclaimed hill where it has cut a small gully. The water then flows over an open <br />flat reclaimed hillside to the bottom of the hill (photo 7) where it reconnects with the west flowing segment of <br />Ditch D -F 15 to Pond F. <br />PROCESSING WASTE /COAL MINE WASTE PILES — Rule 4.10 and 4.11 <br />Drainage Control; Surface Stabilization; Placement: <br />In an aerial photo taken March 16, 2012, the coal mine waste (CMW) that was being stacked on gob pile <br />#4 was wet enough to flow down the south slope of the gob pile (photo 8). The gob flowed down the hillside, over <br />ditch D -D8 (and bench) and stopped at the lower gob pile access road. Bill Bear explained that weather conditions <br />have not been favorable for drying and compaction of the gob. Therefore, it was being stacked (piled) for drying <br />and with limited space, the stacked wet material flowed down hill. No material flowed beyond the extent of the <br />gob pile, no topsoil was lost, no access /haul roads were obstructed and there were no off -site impacts. <br />Cover fill material was being moved from the cover fill pile (east of gob pile #2 topsoil stockpile) to the cover fill <br />stockpile east of pond F to make additional room for gob material. During the inspection, gob material was <br />dumped, layered and compacted. <br />Bill Bear authorized the installation of new piezometers used in gob pile monitoring that were damaged beyond <br />repair. The locations of the damaged piezometers are shown in the Stover & Associates 4th Quarter 2011 Coal <br />Mine Waste Bank Inspection Report. <br />ROADS — Rule 4.03 Construction 4.03.1(3)/4.03.2(3) Drainage 4.03.1(4)/4.03.2(4) Surfacing and <br />Maintenance4.03.1(5) and (6)/4.03.2(5) and (6) Reclamation 4.03.1(7)/4.03.2(7): <br />The coal mine waste haul road was dry, well maintained, passable and roadside ditches were in place.
