July 26,2011 C-1981-019/Colowyo Coal Mine JHB RECLAMATION SUCCESS -Rule 4.15, Rule 3: 2010 reclamation block in the West pit is showing good seedling emergence. The cover is thin as would:be expected with first year vegetation establishment. Annuals forbs are present but not problematic and noxious weeds were not in evidence. Rilling was not problematic in this 2010 West Pit reclamation block. Gullies previously identified in this block have been repaired and runoff source rerouted. Several spoil springs/seeps appear to have formed in the 2010 and 2009 WP reclamation parcels. CCC will need to visually monitor these seeps. One of the seeps flows onto one of the contour ditches and pools in a low spot corresponding with a gully repair. Grading of the contour ditch to provide positive drainage is needed in this segment of ditch. Rill and gully repair in West pit and east pit have been completed. Repairs look good. North drainage of 2010& 2009 East Pit parcel continue to have concentrated runoff not going into the drainage. CCC will need to monitor the gully repairs and may need additional contour ditches places above the gully areas to direct runoff into the appropriate drainages and stock tanks. REVEGETATION—Rule 4.15 Vegetative Cover; Timing: SL5 East Pit vegetation looked very robust with very few noxious weeds. Areas identified during the bond release inspection in September 2010 were attempted to be located. Patch 3 continued to have sporadic Canada and Musk thistle but would not be considered an infestation,more of a smattering of plants. Other treated patches were difficult to locate. Weed management efforts appear to have been successful. TOPSOIL—Rule 4.06 Removal 4.06.2; Substitute Materials 4.06.4(4); Storage and Protection 4.06.3; Redistribution 4.06.4: CCC was implementing variable depth topsoil placement in the West Pit 2011 reclamation parcel(102 area). Soil is end dumped at the top of the slope,then pushed downhill with DI I dozers. CCC has extensively placed soil thickness stakes along the slopes to guide the dozer operators to the required soil thickness along the bands of the slope. This appears to be very effective. Topsoil is being used from the topsoil pile east of"Hink's"Peak. Topsoil replacement was beginning on the East Pit 2011 reclamation parcel. Topsoil thickness was not verified during this inspection since this process is still actively occurring.
