September 20, 2011 C- 1981 - 038 /13owie No. 1 Mine JJD <br />three paved entrance roads to the unit train loadout were in good condition. <br />RECLAMATION SUCCESS - Rule 4.15, Rule 3: <br />The backfilled slopes at the East Mine showed no signs of slope stability problems, such as cracking or <br />slumping. The roughened grading of those same slopes is working to prevent gullying and retain moisture. Some <br />of the backfilled slopes had been recently reworked by roughening up the grading and, then, hydroseeded. There is <br />a moderate cover of vegetation on the slopes that had not been reworked. <br />The reclamation of the West Ridge waste pile and the old waste pile has been successful. The two piles are stable <br />and have a good vegetative cover. <br />The reclamation work at the West Mine also appears to be successful, although the East Roatcap Creek four foot <br />diameter culvert still needs to be removed and the stream channel reestablished. The backfilled and graded slopes <br />appeared to be stable and the vegetative cover was fair to moderate. <br />REVEGETATION — Rule 4.15 Vegetative Cover; Timing: <br />Brock Bowles of the Division examined the vegetative cover at the East Mine. At the reclaimed utility <br />bench, the species identified included, but were not limited to, wheat grasses, Indian rice grass, alfalfa, four wing <br />salt brush, Wood's rose, Lewis' flax, Cicer milkvetch and sunflowers. There was a lot of prickly lettuce, some <br />tumble mustard and Alysum, a little cheat grass and isolated occurrences of thistle. There was a large patch of <br />Russian knapweed at the lower end of the road culvert that is above and to the northwest of the West Ridge waste <br />pile. The knap`veed, thistle and cheat grass need to be attended to soon as they are on the Colorado Noxious Weed <br />list. There also were areas of tamarisk at the East Mine just below pond no. 2 and between pond no. 1 and pond <br />no. 2. <br />The vegetative cover of the backfilled and graded slopes at the West Mine was fair to moderate. The vegetative <br />cover was not uniform over the entire area. The facilities bench outslope at the unit train loadout had a good <br />vegetative cover. The partially backfilled slopes and the flat area at the partially reclaimed highway coal stockpile <br />area had a moderate cover of vegetation. <br />SLIDES and DAMAGE - Rule 4.12: <br />No indications of cracking or bulging were observed with any of the backfilled and graded slopes at the <br />East Mine, West Mine and reclaimed run -of -mine coal stockpile area. <br />SUPPORT FACILITIES - Rule 4.04: <br />There were no problems with any of the remaining structures at the unit train loadout. There were no rail <br />cars on site at the loadout or at the partially reclaimed highway coal stockpile area spur line. <br />SIGNS AND MARKERS — Rule 4.02: <br />Surface disturbance markers were up around the disturbed areas at all of the Bowie No. 1 Mine sites. The <br />two subsidence warning signs were up along Steven's Gulch road just east of the well field area. Mine <br />identification signs were up at all of the entrances and along the public roads where the permit boundaty crosses <br />Number of Partial Inspection this Fiscal Year: 2 <br />Number of Complete Inspections this Fiscal Year: 1 <br />Page 4 of 7 <br />
