September 3, 2014 C- 1981 - 022 /Elk Creek Mine BFB diversion ditch uphill and east of Pond D needs to be cleaned (photo 2). Some large rocks and soil have fallen into the ditch. The screen at the end of the clean water diversion ditch was clean and free of debris. There are two black plastic pipes that end in Elk Creek just north of Pond D where Elk Creek goes into the culvert (photo 3). The pipes enter the ground under the haul road and it is unclear where the pipes originate. The purpose of the pipes needs to be determined and if they are discharging to Elk Creek. The culvert by the main entrance sign, just west of Pond A needs to have the debris removed on the inlet side (photo 4). The gob vent boreholes for Panel 18 were inspected for drainage control and siltation structures. Gob vent boreholes are constructed according to the `typical' gob vent borehole drill pad SAE design outlined in Exhibit 2.05 -E3 Section 9. The following is a list of the well pads with their discrepancies. - The well pad drainage ditch does not have a sediment control structure. A structure needs to be installed in the ditch on the following drill pads: 18 -02 (photo 5), 18 -02b, 18 -03, 18 -04b, 18 -04c, 18 -07b and 19 -08. -The straw wattles on the pad perimeter are in disrepair and have become ineffective. The most common reasons were they are full of sediment or were not installed. The wattles need to be repaired /installed on the following drill pads: 18 -01b (photo 6), 18 -02, 18 -02b, TGBMPA, 18 -03, 18-04,18-04b, 18 -04c (photo 7), 18 -05, 18 -08, and 19- 08. The berm around 18 -02 needs to be repaired to prevent water from running down the face of the fill. A berm around the TGBMPA pad perimeter needs to be installed (photo 8). Water gullies were forming from the pad edge down the face of the fill material. Erosion wattles need to be installed at the base of the TGBMPA topsoil stock pile to prevent soil from eroding down the small side gulley. RECLAMATION SUCCESS - Rule 4.15, Rule 3: The vegetation on the II West Valley fill looked good. The upper part that was seeded last year had many annuals, as expected, and new perennial grasses were seen in the understory. The thistles in the II West and West Valley Refuse Areas have been treated. Thistles need to be treated on the following gob vent bore hole pads: 18 -01b, TGBMPA, 18 -04c, 18 -05, 18 -07b, 18 -08 and 19 -08. Houndstongue plants need to be treated on the following gob vent bore hole pads: 18 -04b, 18 -04c and 18 -08. There is very little vegetation on the fill slope of pads 18 -02b (photo 9) and 18 -04b. These areas need to have wattles installed at the toe and mid -slope to prevent erosion during spring runoff and needs to be seeded.
