from Steven's Gulch Road, the superstructure of which has been removed for reclamation, the 500,000-gallon water tank and well house at the Steven's Gulch well field, and the Bowie No. 1 West Mine pipeline. These facilities are described in Section 2.05, and maps are found in Volume 8A. The main East Mine facilities area is located east of Steven's Gulch Road. All of the mine buildings and coal handling structures have been demolished. Demolished facilities included the office/bath house building, the warehouse and shop, a crushing and screening building, a transfer tower, conveyor structures, and a truck loading station. These structures were either disposed of offsite or buried in place. Concrete foundations and piers were broken up and buried in place. In addition, two water tanks (100,000 gallon and 200,000 gallon) were located on the north end of the disturbed area and were removed. Also, a fueling area, a sewer plant, and waste oil storage tank were part of the facilities. The superstructure of the fueling area has been demolished and disposed of offsite. The sewer plant and waste oil storage tank have been removed. The concrete foundations of the fueling facility and the waste oil storage tank were broken up and buried in place. The coal which had been stockpiled at the crusher/screener bench and at the highway coal stockpile next to the train loadout, was transported by truck to the Bowie No. 1 loadout and shipped out by rail. The highway coal stockpile area was covered in one to two feet of soil and seeded and mulched in order to temporarily stabilize the area until final reclamation. The adits at the Bowie No. 1 main East Mine were backfilled with compacted, non-combustible fill in 2001. Facilities at the Bowie No. 1 West Mine portal bench area included three portals, a warehouse, shop, fueling station and rockdust tank. A substation provided a power linkage to the mine. All of the facility structures at the portal bench area were dismantled and removed offsite. Some of the equipment was transported to the Bowie No. 2 Mine for use. Concrete foundations were broken up and covered before the backfilling and grading operations began. The three portal adits were backfilled with compacted, non-combustible material in 2000. After structural demolition, the West Mine portal bench area was backfilled and graded. The portal bench backfilling and grading operations began in 2000. Because of site constraints, it was not possible to backfill and grade the entire site in one operation. Complete excavation of the fill material and removal of the East Roatcap Creek culvert would not leave enough room to construct a new sediment pond to treat the runoff from the reclaimed area. Therefore, BRL decided to reclaim the site in two separate stages. The first stage involved backfilling and grading the upper two thirds of the site and leaving the East Roatcap Creek culvert and about 10 feet of cover fill in place. About 300,000 yds of fill were moved, with 10,000 yds remaining. This allowed enough room to construct two new sediment ponds directly over the East Roatcap Creek culvert. Once the upper area is stabilized with vegetation, stage two will begin. The remaining fill over the East Roatcap Creek culvert will be excavated, eliminating the two new sediment ponds. Then the East Roatcap Creek culvert will be removed. If needed, another new, but smaller, sediment pond will be constructed at the down gradient end of this disturbance. A 200,000-gallon water tank and ventilation fan were part of the West Mine fan area, which lies one-quarter mile north of the portal cut. The ventilation fan structure and the water tank were dismantled and removed offsite. In 2000, the ventilation fan shaft was filled with a layer of non- combustible material, followed by coal refuse from the run-of-mine coal stockpile. The ventilation shaft was reworked because the fill settled. After the fill stabilized, the shaft was topped with non-combustible material. A concrete plug, reinforced with rebar, was poured over the filled-in shaft, and, then, covered with dirt. 25
