April 10, 2012 C- 1981 - 022 /Elk Creek Mine BFB Culvert DBa (south of the rock dust tank) is shown on Map 2.05 -M4 passing under the light use road delivering water from Ditch D6 to Ditch D2 west of the main haul road and ultimately through sediment traps to Elk Creek. Jim Kiger explained that due to the amount of rock dust from the nearby rock dust tank that was collecting in Ditch D6, the culvert was redirected to pass under the main haul road delivering water to ditch D5 which drains to D Pond. This change in culvert design needs to be documented on mine maps and it also needs to be determined that Pond D is sufficiently designed to handle the additional runoff from the slope above Ditch D6. Ditch D5 middle (south of lamp house) needs to have soil debris removed (photo 1), be excavated for better water holding capacity (photo 2) and have steel panels removed (photo 3). Ditch D6 (behind Elk Creek Fan), ditch D4 and ditch along West Valley Haul Road are clean and appear to be functioning properly. The sediment traps at culvert DB (north of lamp house) need to be cleaned. The culvert at the bend in the West Valley Haul Road below the cemetery needs to be cleaned. PROCESSING WASTE /COAL MINE WASTE PILES — Rule 4.10 and 4.11 Drainage Control; Surface Stabilization; Placement: The coal waste was recently compacted on the II West Refuse Pile. Soil was being salvaged from the hillside and placed on the down -slope of the refuse pile in preparation for seeding. ROADS — Rule 4.03 Construction 4.03.1(3)/4.03.2(3) Drainage 4.03.1(4)/4.032(4) Surfacing and Maintenance4.03.1(5) and (6)/4.03.2(5) and (6) Reclamation 4.03.1(7)/4.03.2(7): All roads in the mine facility area were well maintained and passable. A water truck was spraying water for dust suppression on the haul roads. Many sizable rocks had fallen onto the Hubbard Creek county road from the steep cliff areas above. The road is still passable but the county needs to clear the rock debris. The Bear Creek road was well maintained and has two locked gates to control traffic. REVEGETATION — Rule 4.15 Vegetative Cover; Timing: Plants and grasses were starting to sprout on the Hubbard Creek Fansite. Jim Kiger said the area was seeded last spring and last fall. Most species at this stage were too young to identify. Weeds will be treated later in the growing season SUPPORT FACILITIES - Rule 4.04: The second Bear Creek fan was being assembled. The site is well maintained and clean. The fence is down during the construction. SIGNS AND MARKERS — Rule 4.02: The boundary disturbance markers are in place around the Bear Creek Fansite during construction. Mine ID signs were in place at the main entrance, east yard entrance, along HWY 133 and the Hubbard Creek Fansite. Top soil signs were in place at the Elk Creek topsoil pile and II West 1 topsoil stockpile.
