RULE 2 - PERMITS Coal Handling Structures The location, construction, use, maintenance, and removal of coal handling and transportation structures are described in the following section and shown on Map 2.05.3 -M1A, Mine Facilities Map (South End). The coal handling structures and facilities will include: • ROM Conveyor • Transfer Building • Transfer Conveyor to Radial Stacker • Radial Stacker and Coal Stockpile • Truck Loading Area • Coal Haulroad During the initial mine development phase, coal from the development portals will be transferred by conveyor to the mine portal area, where a large wheel - loader will load trucks, which will move the coal to the coal stockpile area using the portal ramp. A temporary belt will then be installed to convey coal from the portal area to a 50 -foot high radial stacker with a 250 -foot boom, which will allow distribution of coal to the center of the coal stockpile area, where tracked dozers can distribute the coal within the defined stockpile area. The coal stockpile will have a maximum capacity of approximately 100,000 tons, and will be managed for inventory and blending purposes. A truck - loading area on the south side of the coal stockpile will allow tractor - trailer coal haulers to turn- around empty and pull in to be loaded by a front -end loader. Following loading, the loaded coal haulers will exit the property on the coal haulroad (previously described under the "Roads" Section) to RCR27, where the coal will be hauled to coal customers. Once initial development is completed, a ROM conveyor will be extended from the main conveyor portal to the transfer building, located adjacent to the coal stockpile area. The ROM conveyor will be a 72 -inch covered conveyor extending approximately 100 feet from the portal area to the top of the transfer building. The ROM conveyor will be elevated on six steel -frame bents of graduated height mounted on 4 -foot diameter concrete pylons extending approximately 30 -feet below grade. The transfer building was previously described under the "Mine Facilities" Section. A 72 -inch covered transfer conveyor will convey coal from the transfer building to the top of a stack tube. A transfer conveyor will extend to a second stack tube to allow storage of additional coal which could be used to blend to customer specifications. The transfer conveyor will be approximately 300 feet long and will be supported by two steel -frame bents approximately 30 feet high, mounted on 4 -foot diameter concrete pylons extending approximately 30 -feet below grade. Coal Refuse and Non -Coal Processing Wastes General and detailed plans for coal refuse piles are described and referenced in full compliance with applicable provisions of Rules 4.10 and 4.11. Limited volumes of underground development waste will be generated from fault crossings, overcast development, material from roof falls, and possible future development of ventilation shafts. To the extent practical, this material will be disposed of underground in mined -out areas. Coal refuse material (development waste and non - specification TR -01 -10 2.05 -28 Revision 02/11
