Pg 2/3 West Elk C-SO-007 20 July 2004 Hydrologic Balance (cont): No erosional features were noted on the embankment of the RPE pond. - Pond MB-2R contained water at the time of the inspection but was not discharging. The pond needs to be cleaned, especially at the pond inlet. This was noted to the operator at the time of the inspection. The emergency spillway is a riprapped open channel and appeared to be stable and in good condition. The pond embankment was stable and well vegetated at the time of the inspection. No erosional features were noted on the embankment. - Pond MB-3 contained water at the time of the inspection but was not discharging. The pond needs to be cleaned, especially at the pond inlet. This was noted to the operator at the time of the inspection. The pond embankment was stable and well vegetated at the time of the inspection. No erosional features were noted on the embankment. - Pond MB-5 contained a small amount of water but was not discharging at the time of the inspection. The primary spillway is a gated valve and the emergency spillway is a riprapped open channel. The emergency spillway appeared to be stable and in good condition. The pond embankment was stable and well vegetated at fhe time of the inspection. No erosional features were noted on the embankment. - Pond MB-4 is a small concrete pond located at the loadout.

It contained some water but was not discharging at the time of the inspection. The emergency spillway is a raprapped channel. It appeared to be stable and in good condition at the time of the inspection. The pond embankment was stable and well vegetated at the time of the inspection. No erosional features were noted on the embankment. -All of the roadside ditches (including those along the main access road, the Sylvester Gulch haul road, the RPE haul road and the roads behind the facilities area) were all well maintained and in good condition. - The ditchs around the lower refuse pile and the coal stockpiles are concrete ditches. There is some sediment in these ditches from the recent rains and they should be cleaned out. This was noted to the operator at the time of the inspection. The riprapped portion on the steep, west-side of the LRP was stable and in good condition. -Several of the methane degas well pads were visited on this inspection. These included MDW-15-07, 16-7, 17-09, 24-01, 24-02, 24-03 and 24-05. All of the pads had silt fence for sediment control. The silt fence was properly installed and there was no sediment leaving the pads to the adjacent undisturbed areas. Processing Waste: The lower refuse pile slopes were well vegetated and appeared to be stable at the time of the inspection. There were no erosional problems noted on the slopes. The top of this pile is used as a material storage area. The edge of the area is bermed to keep water from running over the outslopes of the pile. The water is directed into the permanent ditches around the pile. - An approximately 1-acre portion of the refuse pile expansion has been covered, topsoiled, seeded and mulched (erosion matting was stapled over the slopes). This area appeared to be stable at the time of the inspection.
