May 26, 2011 C-1981-038Bowie No. 1 Mine JJD ROADS—Rule 4.03❑❑Construction 4.03.1(3)/4.03.2(3)❑�]Drainage 4.03.1(4)/4.03.2(4)❑❑Surfacing and Maintenance4.03.1(5)and(6)/4.03.2(5)and(6)❑❑Reclamation 4.03.1(7)/4.03.2(7): The entrance road at the East Mine was in good condition. This road had been paved up to the former crusher/screener bench but the asphalt was removed for reclamation. The operator has maintained road ditches and has established cross drains across the road in order to minimize road erosion. An additional cross drain on the road section on the west side of the reclaimed portal bench area would be helpful since a rill is beginning to form in the road. The graveled entrance road to the reclaimed run-of-mine stockpile area was passable and in good condition.The one cross drain across the road had sufficient capacity. The public road leading to the West Mine and the public road and mine road leading from the reclaimed West Mine area to the reclaimed West Mine fan site was also passable, although there was standing water in a couple of places along the mine road. The road leading to the well field was muddy but passable.The three paved entrance roads at the unit train loadout area were dry and in good condition.The dirt road at the partially reclaimed temporary highway coal stockpile area was damp but passable. RECLAMATION SUCCESS -Rule 4.15,Rule 3: The reclamation work at the East Mine has been successful so far. The backfilled slopes appeared to be stable and the rough grading has stabilized the slopes as far as erosion is concerned. There is a good stand of vegetation on the lower slopes and a fair vegetative cover on the upper slopes.The upper slopes had been revegetated but additional grading operations require reseeding. The operator has the seed and will begin reseeding operations as soon as the weather cooperates. Across the road from the East Mine,the reclaimed run-of-mine coal stockpile area is holding up very well. The roughened grading has helped to establish a good vegetative cover.The reclaimed slopes were stable. The reclamation work at the West Mine has been good.The slopes are stable and have a good vegetative cover. The 48 inch diameter culvert in East Roatcap Creek will need to be removed and the drainage channel reestablished to complete the reclamation at the West Mine. There had been structural demolition work performed at the unit train loadout.The three concrete silos,conveyors, grizzly and railcar loading structures had been removed and approved for bond release.The partial reclamation work at the temporary highway coal stockpile area involved removing the coal and covering the pad with dirt, followed by temporary seeding. The site has a moderate vegetative cover and the cut slopes are stable.There was no erosional gullying at the site. REVEGETATION—Rule 4.15❑❑Vegetative Cover;Timing: The lower slopes of the backfilled and graded disturbed areas at the East Mine had a good vegetative cover.The grading left depressions in the backfill for runoff to accumulate,which helps the revegetation efforts. The upper slopes will need reseeding due to additional grading work that had been done after the original reseeding. The vegetative cover on these upper slopes was fair but the operator anticipates reseeding soon.
