June 19,2013 C-1980-007/West Elk Mine JRS perform any maintenance/repair work, as necessary. The pad was well graded to allow for positive drainage off of the site and there were no erosional problems noted on the pad at the time of the inspection. There was a small drainage channel constructed on the side of the pad. This drainage was stable and functioning as designed. The water from this small drainage channel flows through several straw waddles then out to the undisturbed area. There was no sediment behind any of these straw waddles or in the undisturbed areas. There was a lot of slash placed on the pad to help limit access and control erosion. There was an active spring at the upper edge of the reclaimed pad(off of the pad in the undisturbed area)with several bear and elk tracks. This active spring may be part of the reason there are the cracks in the reclaimed area. The MDWs were plugged and sealed and MDW 6- 21-25.5 was marked but there were no borehole maker in place for MDW 6-21-28. A borehole marker for MDW 6-21-28 will need to be placed at the site of the MDW prior to the Division approving the SL-05 bond release. There was a lot of good first-year vegetative growth on the pad,with perennial grasses and forbs present. Although not a Phase I Bond Release criterion,all of the stripped topsoil has been replaced on the drill pad. No topsoil depth measurements were taken as all stripped topsoil on a drill pad is stockpiled on site and replaced on that site following backfilling and regrading. Overall,the reclamation on the fourth and final drill pad in Box Canyon was excellent and completed in accordance with the approved reclamation plan. -The drill pad for MDWs E4-80.5/81.5/83 was constructed but the MDWs were never drilled. The pad was well graded and stable and was graded well to blend with the surrounding undisturbed areas. There was no cracking, slumping or settling noted on the pad. The pad was graded to allow for positive drainage off of the site and there were no erosional problems noted on the pad at the time of the inspection. The outslopes of the pad were very steep but remained stable. There was no erosion noted on the pad or outslopes at the time of the inspection. There was a lot of slash placed on the pad to help limit access and control erosion. There was no sediment noted off site in any of the undisturbed areas. There was a lot of good first-year vegetative growth on the pad,with perennial grasses and forbs present. Although not a Phase I Bond Release criterion, all of the stripped topsoil has been replaced on the drill pad. No topsoil depth measurements were taken as all stripped topsoil on a drill pad is stockpiled on site and replaced on that site following backfilling and regrading. Overall,the reclamation on this drill pad was excellent and completed in accordance with the approved reclamation plan. - The pad for MDW E1-15 is extremely steep. The pad was well graded and remained stable at the time of the inspection. The reclaimed pad was well blended with the surrounding undisturbed area. There was no cracking, sliding, settling or slumping noted on the pad at the time of the inspection. Due to the extreme steepness of the reclaimed pad,it was regraded with three small terraces,with each bench being approximately five feet in width. Each terrace bench had straw waddles to help control runoff. Additionally,the entire site was covered with coconut fiber matting to help stabilize the ground and control erosion. The site had positive drainage and, as stated above, sheet flow was controlled by the slight terracing and the use of straw waddles. There were no erosional problems noted on the reclaimed pad and no sediment was observed either behind the straw waddles or in the adjacent undisturbed areas. There was a lot of good first-year vegetative growth on the pad,with perennial grasses and forbs present. There was also a lot of serviceberry and snowberry observed on the pad. Although not a Phase I Bond Release criterion, all of the stripped topsoil has been replaced on the drill pad. No topsoil depth measurements were taken as all stripped topsoil on a drill pad is stockpiled on site and replaced on that site following backfilling and regrading. The entire site was fenced with electric fencing to keep cattle and wildlife off of the pad until it is further stabilized. Overall,the reclamation on this drill pad was excellent and completed in accordance with the approved reclamation plan. -The drill pad for MDW E1-19 is below pad E1-15. The pad was well graded and remained stable at the time of Number of Partial Inspection this Fiscal Year: 9 Number of Complete Inspections this Fiscal Year: 4 Page 4 of 53
