September 20, 2011 C- 1981 - 038 /13owie No. 1 Mine JJD <br />During the May 26, 2011 OSM Federal inspection, it had been thought that, possibly, there was no gradient to a <br />section of the West Ridge waste pile upland diversion ditch. The operator surveyed the ditch and found that there <br />was a positive 1.19% flow gradient towards the road so the ditch was not redug. The resulting disturbance would <br />not have made it worthwhile (Figure 4). <br />There was no standing water in the two upper bin wall sediment ponds, ponds nos. I and 2, at the East Mine. As <br />had been documented in the Division's July 27, 2011 inspection report, the tree branch that had become lodged in <br />the primary discharge tube was removed. This had been one of the issues during the May 26, 2011 Federal <br />inspection (Figure 3). Pond no. 2 had been recently cleaned out. The operator had spread the pond cleanings along <br />the reclaimed shoulder of the main dirt road and hydroseeded it. The discharge structures of the two ponds were <br />functional. <br />The two sediment ponds at the West Mine, ponds W -1 and W -2, were also dry. Pond embankments were grassed <br />and appeared to be stable. The open channel emergency spillways were free of any blockage. <br />The sediment pond at the reclaimed run -of -mine coal stockpile area was dry. The pond's primary discharge gate <br />was closed. There was no debris in the open channel emergency spillway. The collection ditch leading to the pond <br />had ample capacity. Steven's Gulch was flowing. <br />The bin wall sediment pond at the unit train loadout was dry as well. The upland diversion ditch and culverts were <br />in place on the north side of the pond. There was irrigation water flowing in the Farmer's Ditch located underneath <br />the bin wall sediment pond. The collection ditch and half culvert downdrain were in place on the west side of the <br />loadout site. The upland diversion ditch and culvert system in the center of the loadout site was operating properly <br />in passing the flow from irrigation. The pond at the partially reclaimed highway coal stockpile area was dry. <br />PROCESSING WASTE /COAL MINE WASTE PILES — Rule 4.10 and 4.11 Drainage Control; Surface <br />Stabilization, Placement: <br />The West Ridge waste pile had a good vegetative cover. The pile's benches were stable. Also, the <br />terraces' collection ditches were in place. The old waste pile also had a good vegetative cover and no signs of <br />slope instability were observed. <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 operator had recently narrowed the former haul road at the East Mine by roughening up the shoulders <br />of the road. Since the last inspection, the shoulders of the narrowed dirt road had been hydroseeded. The pond no.2 <br />cleanings that had been spread out over the road's shoulder looks a little artificial but, hopefully, will blend in over <br />time. Cross ditches had been cut into the road for drainage to the road side ditches. <br />The dirt road leading to the West Mine from Steven's Gulch road was passable. Road culverts were functional. <br />The dirt entrance roads to the well field, reclaimed run -of -mine coal stockpile area and the partially reclaimed <br />highway coal stockpile area were passable. The dirt road leading to bin wall pond no. 1 was passable as well.
