September 21, 2017 C-1981-038/Bowie No. 1 Mine CCW <br /> <br /> <br />Number of Partial Inspection this Fiscal Year: 4 <br />Number of Complete Inspections this Fiscal Year: 1 <br /> <br /> Page 4 of 9 <br /> <br />- Binwall Pond #4 (Photo 4) <br /> Reclamation activities occurred at this site in the late summer of 2017. These activities included backfilling, <br />regrading and drainage control. The binwall was removed and the remaining embankments were blended into the <br />surrounding hillsides. The bottom of the pond was recon figured to promote drainage and match the surrounding <br />natural channel. Pond #4 was the last in the series of the 4 binwall ponds. Silt fencing and hay bales were placed <br />at the end of the disturbed area at the outlet of the site to the natural channel. T hese measures were put in place to <br />reduce the amount of sediment leaving the site. Evidence of a large recent flow was observed at the outlet due to <br />the silt fencing being ripped in the middle of the channel. The area was going to be repaired shortly aft er the <br />inspection. The sediment control measures will be redesigned to accommodate larger flows. The site was stable <br />and in good repair. The reclaim area will be reseeded in the early fall of 2017. <br /> <br />- ROM Pile Pond (Photos 5 and 6) <br /> Reclamation ac tivities conducted at the ROM Pile Pond included backfilling and regrading the pond, removing <br />and regrading the access road, and establishing drainage control on the site. The activities were completed in the <br />late summer of 2017. The site was stable and there were no major erosional features observed. Sediment control <br />on the site included berms, silt fencing and later hay bales. When the site was originally visited on September 19, <br />there were only silt fences and berms in place. It was noted that the f low of water had gone to a low point on the <br />reclaim area and breached a portion of the berm. During the course of the bond release inspection, repairs and a <br />minor design change were applied to the reclaim area. The berms and silt fencing remained in plac e and where the <br />breach had occurred, an outlet and hay bales were installed. This new design would allow water to continue to exit <br />the site at the low spot; however the water would go through the hay bales as treatment to reduce the amount of <br />sediment leaving the site. The line of wattles leading to the lower part of the pond require maintenance: some were <br />silted in, more stakes were needed in some locations, and some should be trenched in better (deeper). <br /> <br />The four remaining ponds at the mine include t he Loadout Pond, the Highway Pond, the West Mine WS -1 Pond <br />and the West Mine WS-2 Pond. <br /> <br />- The Loadout Pond and the Highway Pond are located at the Paonia Loadout. During the inspection both ponds <br />were dry. The embankments are well vegetated and stable. There were no indications of erosion. <br /> <br />- The WS-1 and WS-2 Ponds (Photo 7) are located at the West Mine below the reclaimed facilities and portals. <br />Both of the ponds are very well vegetated and stable. The ponds were dry at the time of the inspection. There <br />were no erosional features identified. <br /> <br />Ditches 1, 2, 3 and 6 are along the haul road at the East Mine. During the inspection there was not any water in the <br />ditches. There were no obstructions or erosional issues identified in the ditches. Ditches 4, 5 and 7 transport <br />runoff down the east side of the reclaimed benches and connects to the natural drainage. The ditches were dry at <br />the time of the inspection. The ditches were stable and in good repair. There were no obstructions identified or <br />erosional issues. <br /> <br />The perimeter ditch around the reclaimed gob pile was dry. There were no erosional issues or obstructions <br />identified.
