• 2-34 <br />2.2.3 Storage and Stockpile Sites <br />The operation will have minor storage systems for fuel (diesel), and a warehouse <br />trailer for non-flammable and non-explosive products. Miscellaneous grease and oils <br />will be stored adjacent to the warehouse building with bulk oils and fuels stored away <br />from the building as shown on Figures 2.2-2 and 2.2-6. <br />Coal extracted underground will be conveyed to a crushing and screening plant <br />located immediately outby the belt entry. The sized coal will then be conveyed to a <br />coal stockpile by a 120-foot long radial stacking belt. Coal from the stockpile will be <br />loaded into on-highway trucks by front end loader(s). Alternatively, the coal may <br />bypass the screen and crusher and be placed, unsized, in the coal stockpile. The coal <br />stockpile will be isolated from all surface water run-off as described in Section 2.4.1 <br />and maintained at a minimum volume. The coal stockpile will be limited in capacity to <br />20,000 tons. <br />Topsoil will be stockpiled as shown on Figure 2.2-2 and described in Section <br />2.3.4. A rip-rap stockpile and soi! stockpile are located west of the topsoil stockpile as <br />• shown on Figure 2.2-2. This stockpile will be known as the construction material <br />stockpile. The construction material stockpile is debris from cleaning ponds and <br />ditches and general site clean-up. The rock from this stockpile may be periodically <br />utilized to stabilize erosion features. The soil from this stockpile may be utilized for <br />construction of the new mine entrance road (TR-05) or other DMG approved <br />construction. activities. Material from this stockpile may also be utilized during the final <br />reclamation process. The footprint of this stockpile will not be enlarged without DMG <br />approval. <br />In the footprint of the construction material stockpile, topsoil was stripped to a <br />depth of 12-inches and placed in the topsoil stockpile. The resulting depression along <br />with a perimeter ditch and sediment trap are used to retain the run-oft from the <br />construction material stockpile. Calculations demonstrating these controls will retain <br />run-off from a 25 year 24 hour event within the area (SAE-3) are contained in Appendix <br />M. The topsoil stockpile and construction material stockpiles will be seeded with the <br />temporary revegetation seed mix in the fall of each year they are disturbed. No <br />seeding will be necessary if the piles are not disturbed during the year. <br />• M`Clane <br />Volume 1 <br />12/99 <br />
