June 19, 2012 C -1980- 007 /West Elk Mine JRS <br />RECLAMATION SUCCESS (cont.): - The Lone Pine portal area was reclaimed in 2002 and encompassed an <br />area of approximately 2.0 acres. The area was dry but was well vegetated and stable. The majority of the <br />reclaimed area is grassland, with mountain brome, fescue and slender wheatgrass being the dominant species. <br />There is some oak brush starting to encroach onto the reclamation at the interface with the undisturbed. The area <br />is very steep but no erosional problems were noted on the reclaimed areas. Overall, the reclamation on the Lone <br />Pine portal area is very good. <br />- The Lone Pine topsoil stockpile and borrow area was reclaimed in 2002 and encompassed an area of <br />approximately 0.5 acres. The area was dry but was well vegetated and stable. The majority of the reclaimed area <br />is grassland, with mountain brome and slender wheatgrass being the dominant species. There is some oak brush <br />starting to encroach onto the reclamation at the interface with the undisturbed. No erosional problems were noted <br />on the reclaimed areas. Overall, the reclamation on the Lone Pine topsoil stockpile/borrow area is very good. <br />- The Lone Pine development waste pile area was reclaimed in 1996 and encompassed an area of approximately <br />1.0 acres. The area was very dry but was well vegetated and stable. The majority of the reclaimed area is <br />grassland, with mountain brome and western wheatgrass being the dominant species. There is some oak brush <br />starting to encroach onto the reclamation at the interface with the undisturbed. No erosional problems were noted <br />on the reclaimed areas. Overall, the reclamation on the Lone Pine development waste pile area is very good. <br />- During the two days of the inspection, the Division inspected approximately 41.1 of the 67.6 total acres <br />requested for release. This amounts to approximately 61% of the entire area. All of the areas were found to be <br />very well vegetated and stable, with no erosional problems noted at any of the sites. In addition to the on the <br />ground inspections, a number of the remaining sites were seen from inspected holes. Again, all of these sites were <br />well vegetated and stable, with no erosional problems noted. The grasses and forbs on the sites were species that <br />provide good cover and forage. There was a good start to shrub reestablishment on the vast majority of the sites as <br />well. Many of the sites did have some noxious weeds (mostly Canada thistle and hound's tongue). MCC will <br />need to spray these areas and continue to monitor and spray them as necessary in the future. Although not a major <br />consideration during a Phase II Bond Release inspection, the weed component did not appear to come close to the <br />maximum allowed Phase III weed limit of 3 %. All of the sites appeared to be progressing nicely towards a Phase <br />III Bond Release. While the Division still needs to review the vegetation monitoring and soil loss data contained <br />in the Phase II Bond Release application, there was nothing on the ground that would indicate carving any of the <br />areas out (this may change based on the data review, however). <br />TOPSOIL — Rule 4.06 Removal 4.06.2; Substitute Materials 4.06.4(4); Storage and Protection 4.06.3; <br />Redistribution 4.06.4: <br />- While no topsoil holes we dug specifically during this inspection, based on the vegetative growth and cover it <br />was obvious that the topsoil has been replaced on these sites. The difficulty in digging specific topsoil depth holes <br />at drill pad and road sites is that there is no specific topsoil depth replacement requirement. The operator simply <br />removes all available topsoil then replaces it at reclamation. Additionally, there were no large piles of <br />unreclaimed dirt seen at any of the sites to indicate that all of the topsoil has not been spread. Finally, MCC did <br />auger holes at the reclaimed sites to assess the topsoil replacement depths. This data will be reviewed prior to <br />proposing a decision on the Phase II Bond Release. <br />This concludes the 19 -20 June 2012 West Elk Partial Phase II Bond Release SL -04 Inspection Report. <br />Number of Partial Inspection this Fiscal Year: 12 <br />Number of Complete Inspections this Fiscal Year: 4 <br />Page 8 of 31 <br />
