July 9, 2014 C- 1980- 007/West Elk Mine JRS <br />with an electric fence to keep the cattle off until vegetation is better established. The MDW was plugged and <br />sealed but not marked, as required by Rules 4.07.3(1) and (2). The reclaimed pad is relatively flat and blends well <br />into the surrounding undisturbed and appears to be AOC. Although the site is fairly flat, it was graded to maintain <br />positive drainage. The surface was disked prior to reseeding and was left in a roughened state. There was some <br />slash on the pad to help control runoff and erosion. There were also straw waddles in the center of the pad to help <br />control the flow of surface runoff. The site did not have anv evidence of instability including settling, slumping <br />and cracking. There were no erosional problems noted on the pad. <br />- The pad for MDW well E2 -30.5 was well vegetated and stable at the time of the inspection. The pad was on the <br />side of the hill and was very steep. The pad was fenced with an electric fence to keep the cattle off until <br />vegetation is better established. The MDW was plugged and sealed but not marked, as required by Rules 4.07.3(1) <br />and (2). The steep reclaimed pad blends well into the surrounding undisturbed and appears to be AOC. The site <br />was graded to maintain positive drainage. The surface was left in a roughened state. There was some slash on the <br />pad to help control runoff and erosion. There were also straw waddles across the entire length and width of the <br />pad to help control the flow of surface runoff and to help control erosion. The site did not have any evidence of <br />instability including settling, slumping and cracking. There were no erosional problems noted on the pad. <br />- The final site we visited on the SL -07 inspection was the Monument Dam borrow area. This is an approximately <br />1.9 acre borrow area for the reconstruction of the Minnesota Reservoir embankment. The area was graded and <br />stable at the time of the inspection. There was good vegetation but it was not fenced and was being actively <br />grazed by cattle. Since this is a borrow area there was a large amount of material removed. The area was, <br />however, blended well to the surrounding undisturbed areas. The area was also graded so that it matches the <br />topography of the surrounding areas. The site had positive drainage. There were no signs of any instability at the <br />borrow area, including settling, slumping or cracking and no erosional problems were noted. There was a small <br />area (approximately 25 -feet square) where a spring has caused a small slump. The area does not appear to be <br />actively moving, as there is vegetation growing in the entire area. Given that this is a small area and it appears to <br />have stabilized, the Division will not exclude this area from SL -07. The Division will monitor this site and, since <br />this is only a Phase I Bond Release, West Elk will still have the liability to perform repairs as necessary. <br />HYDROLOGIC BALANCE - Rule 4.05: Drainage Control 4.05.1, 4.05.2, 4.05.3; Siltation Structures 4.05.5, <br />4.05.6; Discharge Structures 4.05.7, 4.05.10; Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water <br />Monitoring 4.05.13; Surface Water Monitoring 4.05.13; Drainage — Acid and Toxic Materials 4.05.8; <br />Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18: <br />- The Division inspected all of the drill pads and light -use roads included in the SL -07 application for Phase I <br />Bond Release criteria. These include, when applicable, the functioning of drainages with regard to knick - points, <br />blending at disturbance boundaries and channel erosion; erosional features; and drainage control for the reclaimed <br />area, including upslope diversions. <br />- All of the reclaimed roads were graded to allow for positive drainage. The majority of the road length was <br />reclaimed to an ATV trail, with only the edges pulled in and reclaimed. The reclaimed portions of the roads were <br />all left in a roughened state, which will help control runoff and erosion. Additionally, the reclaimed road were not <br />very steep and lengths were short enough to eliminate any adverse affects from sheet flow. There were no <br />erosional features noted on any of the roads at the time of the inspection. Based on the site inspection, the <br />Division believes that all of the light -use roads have been graded in such a way that the drainage control on these <br />areas has been successfully reestablished <br />Number of Partial Inspection this Fiscal Year: 1 <br />Number of Complete Inspections this Fiscal Year: 0 <br />Page 7 of 54 <br />
