No excessive erosion was evident at the MDW pads inspected. Each MDW pad is a Small Area
Exemption as allowed by Rule 4.05.2(3). Sediment control measures employed at the MDW pads
include earthen berms, straw waddles, and straw mulch. Brush from grubbing each pad is placed at the
toe of the outslope of material that is pushed downhill from each pad. This brush stabilizes soil,
reduces runoff velocity, and acts as a sediment filter.
Processing Waste
Construction crews were active on top of the Lower Refuse Pile in the Main Surface Facilities Area
where the coal processing plant is being constructed (work approved in Technical Revision 118).
Construction crews were also active on the Refuse Pile Expansion where the Refuse Conveyor is being
constructed.
Support Facilities
No problems were found at the panel E-1 MDW sites that were inspected: 8,11.5, 26.5, 30, 31.5, 34,
38, 42 (or 41.5), 51, 52, and 54. There also were no problems found at MDW E2-38. No signs of
spills or soil contamination were found where MDW equipment is in place on MDW pads. Operating
equipment on MDWs is enclosed by 6-foot high chain-link fence.
Topsoil
Topsoil stockpiles appeared in good shape at the MDW sites inspected with no signs of excessive
erosion and no weed problems.
General Mine Plan Compliance
The amount of disturbance at each MDW pad appeared to be the minimum necessary for conducting
drilling operations.
Subsidence
No evidence was found that indicates subsidence-caused rockfall in sandstone outcrops over the west
end of Panel E-1, as those outcrops were observed from a distance(see photo below). Subsidence
cracks were found in the surface of the USFS Horse Gulch Road over the recently undermined west
end of Panel E-1 (see photo). These cracks appeared similar to those that have been found in the past
in roads over other longwall panels and which healed over a period of a few weeks (for example, the
main Sylvester Gulch Road where it is near B-seam panel 25).
Documents Received
None.
