• 2.05.3 (7) See 2.05.3(3)(6) and Figures 2.05-1 and 2.05-2 in the Mine Facilities Appendix in Volme 8A. The coal handling structures at the West Mine included: an overhead conveyor belt system, stacker, and ground coal storage. Coal was produced from the West Mine from 1987 through mid 1993 and hauled to the existing truck dump and train Load-out facilities. in mid 1993 the North Mains by-pass was constructed which allowed coal to be handled and processed though the East Mine portals and facilities. (8) Non-coal wastes are disposed of in the Delta County Sanitary Landfill located approximately 12.5 rules southwest of the Easst Mine. Oil and grease refuse are deposited in a 6,000 gallon tank. When this tank is full, a recycling company pumps the tank and takes the oil and grease for reuse. Coal processing waste is placed in the designated waste disposal area. See 2.05.3 (b) and the Waste Disposal Appendix in Volume 6A. Waste rock from the east mine crushing and screening facility is placed in a temporary storage area on the crushing and screening level during the interim period between generation and final placement (Map No. 8-1). The volume of interim storage material is limited to a maximum of 2000 cubic yards. • Grease and oil which is trapped in the retention basins of two grease and oil traps constructed within the drainages of the East Mine are pumped periodically by a local septic pumping company and the contents disposed at the local landfill. Sediment from this system is disposed in the East Mine's waste disposal area. Grease and oil at the West Mine were controlled using retention basins similar to the East Mine. Appropriate facilities were constructed to control oil and grease storage. Policies were developed and implemented to ensure that the operation and maintenance of the fuel bay facilities at the East and West Mine sites is conducted in a manner which minimizes potential adverse environmental impacts. All personnel utilizing these facilities are trained in accordance with the policy as to the proper procedures and maintenance standards required at these facilities. The policy is: 1) require physical attendance during all product transfer operations; 2) establish cleanliness standards for the concrete pads; 3) require adequate cleanup of drips or spills; 4) establish maintenance reporting requirements for fueling facilities and equipment 5) require monitoring and timely maintenance of sumps and drip containers; and 6) establish storage areas and require storage of petroleum products in designated areas at each facility.
