portal bench, through the downhill conveyor line to the coal stockpile at the bottom of the hill and, then to the unit train loadout. Refuse material is trucked from the wash plant to the active refuse disposal areas. There are currently four refuse areas within the permit area, referred to as Gob Piles 91 through 94. Gob Piles 41 and #4 have been filled to their permitted capacity, and will be reclaimed in the fall of 2014. Gob Piles #2 and #3 are active, and used for disposal of refuse material associated with the current mining operations. At the current rate of refuse disposal, it is not likely that the two active disposal areas will have adequate capacity to contain the refuse material to be generated with mining in the Spruce Stomp lease area. Accordingly, the following stipulation is placed on the Division's proposed decision to approved PR -14: PRIOR TO INITIATING ANY LONGWALL MINING IN THE SPRUCE STOMP LEASE AREA (COC- 75916), BRL MUST OBTAIN APPROVAL FOR A PLAN TO MANAGE REFUSE GENERATED AS A RESULT OF MINING ACTIVITIES IN THE SPRUCE STOMP LEASE AREA AND ALL CURRENTLY APPROVED COAL MINING ACTIVITIES. THIS RESTRICTION WILL NOT PRECLUDE DEVELOPMENT MINING ACTIVITIES IN THE SPRUCE STOMP LEASE AREA CONSTRUCTED WITH CONTINUOUS MINING EQUIPMENT. PROPOSED MANAGEMENT PLANS MUST BE PREPARED IN ACCORDANCE WITH RULES 2.05.3(8), 4. 10, AND 4.11 AND BE BASED ON CURRENT AND PREDICTED RATES OF PRODUCTION AND REFUSE GENERATION AND INCLUDE REFUSE THAT WILL BE GENERATED FROM ALL CURRENTLY APPROVED MINING PLANS. A drainage and sediment control system has been constructed. The system consists of ditches, culverts, sedimentation ponds and alternate sediment control areas referred to as "small area exemptions ". Specific details regarding the designs for these systems are presented in Section 2.05, as are references to other sections of the permit application document which present additional design details. For the currently approved operations, all available topsoil has been salvaged and stored prior to facility construction. Salvaged topsoil from the facilities and refuse areas was placed in stockpiles A, D, E, and F. Specific details regarding the topsoil salvage volumes are presented in Section 2.05, Appendices A of Volumes IX and XI, and Map 32 of the Bowie No. 2 Mine permit application. Some surface blasting occurred during construction of the facilities. Details regarding the blasting plan are presented within Section 2.05 of the permit application. The Bowie No. 2 Mine is located in areas known to be subject to mass movement processes. Extensive design efforts and regulatory review were implemented prior to the approval of the Bowie No. 2 Mine and during the review of Permit Revision No. 3 and Permit Revision No. 7. The details regarding the geotechnical aspects of the mining and reclamation plan are presented within Volume VII of the permit application document. The Bowie No. 2 Mine will be reclaimed to the post- mining land uses of rangeland, wildlife habitat and industrial. The approval of Permit Revision No. 6 added cropland and pastureland to the post- mining land uses. All facilities areas and some roads will be reclaimed to reestablish the approximate original contour of the land. All portals, shafts and monitoring wells will be backfilled, in accordance with the applicable rules and with the reclamation details provided Page 22 of 46
