III. COMMENTS -COMPLIANCE Below are comments on the inspection. The comments include discussion of observations made during the inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. Sims and Markers Signs and markers were in place and properly maintained site wide. The mine identification sign at the main entrance to the site is properly displayed. Perimeter disturbance boundary markers were noted at the Elk Creek Fan site construction(see Photograph No. 3) and at numerous other locations along the Elk Creek drainage below the diversion and at the Il-West Refuse Pile. Topsoil pile signs are in place at active GVB sites(see attached Photograph No. 4). Roads The Elk Creek Haul and Access Roads, Bear Creek and Hubbard Creek Access Roads were inspected. Road ditches and road culverts were generally well maintained and road surfaces were graded and stable. The Bear Creek Access Road was being graded at the time of the inspection. Cut slopes along these drainages were stable and no slides or other damage was noted along any of the haul/access roads. Numerous small light use drill roads have been constructed to provide access to isolated methane drainage well drill pad locations (see Photograph No. 5). All roads throughout the permit area were in good condition and maintained. Hydrologic Balance All site Sedimentation Ponds were inspected. None of the ponds were discharging at the time of the inspection. Ponds A, B, and D were retaining water. Ponds C, E and the Substation No. 3 Pond were dry. The sedimentation ponds are all maintained and capable of functioning as intended. Pond embankments, inlets and discharge structures were stable and all ponds were functional. Pond A is containing a large amount of coaly material and appears to be nearing its sediment capacity and should be cleaned in the near future to ensure compliance. Adequate runoff and sediment control has been established at all of the GVB sites. A combination of erosion control netting and straw wattles are in place where needed depending on the grade and location of the drill pad site. An example of the use of this erosion control practice is shown in Photograph No. 6. At this location, GVB-LW15-02,O1A, and 01B are located along a steep canyon road. There are three methane drainage wells installed at this drill (see Photograph No. 7). These are active wells with oil-water separators installed at the surface to remove condensation. One well (GVB-LW15-01B)was venting during the inspection. The drill pad itself is wide and flat but the fill side of the road is steep and susceptible to erosion. As seen in the attached Photo No. 6, erosion control netting and straw wattles have been installed on the fill slope. This site is stable but there is very little vegetative growth on the out slope. The site was broadcast seeded when the erosion control practices were implemented,but additional broadcast seeding may be warranted at this location.
