October 24, 2012 C-1980-007/West Elk Mine JRS
SUPPORT FACILITIES (cont.): - Several active MDW pads were inspected. These included E1-11.5 (which is
being left open for a possible gas purge location if the sealed panel builds pressure), E242, E3-36, E3-40, E3-51
and SOM-3 (a former exploration hole converted into a water monitoring well). All of these pads were stable and
maintained positive drainage. There were no erosional problems noted on any of these pads. All of the topsoil
stockpiles were vegetated and in good condition.
- Several new MDW pads for longwall panel E4 were inspected. These included E4-9, E4-10, E4-12, E4-13 and
E4-14. (Note: The numbering on the panels has changed from designating the cross-cut the MDW intercepts in
the mine to a sequential numbering system). All of the pads appeared to be constructed as permitted and appeared
to maintain positive drainage. All of the MDW's have been drilled, cased and capped at this time. There were no
methane pumps installed on any of the wells the Division inspected. The vegetation(trees and shrubs)that was
grubbed prior to construction was stockpiled below each of the pads. This vegetation will be spread on the pad
following reclamation (as it is on all of the other reclaimed pads). All of the topsoil from the pads has been
segregated and stockpiled, all of the stockpiles have been seeded and mulched and the appropriate "topsoil" signs
are in place. Overall,based on the pads the Division inspected,West Elk(through its contractor Beaver's
Construction)has done a good job.
-The Deer Creek Vent Shaft pad and area was stable at the time of the inspection. The gravel pad was in good
shape. The rock check dams that were in place (as SAE's)were in good condition and appeared to be functioning
as designed. There was no sediment observed leaving the site. The subsoil and topsoil stockpiles both had some
vegetation and both were stable,with no erosional problems noted. Both piles had the appropriate signs in place.
TOPSOIL —Rule 4.06 Removal 4.06.2; Substitute Materials 4.06.4(4); Storage and Protection 4.06.3;
Redistribution 4.06.4:
-The large topsoil piles along the Sylvester Gulch haul road were well vegetated and stable. No erosional
problems were noted on any of the piles. The appropriate "topsoil" signs were in place.
-As mentioned above, subsoil was being added to the live subsoil pile 41. The subsoil was colluvial material
coming from the RPEE. Once West Elk has finished hauling this colluvial material to the pile,the Division
requests that they submit a Minor Revision to update the appropriate volume chart(s) in the permit.
DOCUMENTS RECEIVED: 3Q12 DMR's were hand delivered during the inspection. These were placed in for
scanning on Monday, 29 October 2012.
This concludes the 24 October 2012 complete inspection report for the West Elk Mine.
