pond inspections from 1983 to 1991 show that the pond is adequate for its intended use. Pond 9A-P I normally fills in March, containing an average of 5.0 ac. ft. of water (range 0.7 to 7.5 ac. ft.) and then dries up in late July or August. • This is a valuable source of water for spring and early summer livestock grazing. Furthermore, it is the only accessible water on this property. Pond 9A-PI has only discharged once during the last eight years. This discharge was sampled 3/13/90 and test results show that the quality is adequate for the intended use and will meet State and Federal water quality standards: ph 7.3, E.D. 86.8 t 25° C, oil and grease 0, TDS 94 mg/l. and Settleable Solids <0.2 mVl/hr. RAG Empire will survey Pond 9A-PI immediately prior to final bond release, and if the survey shows any significant build-up of sediment, the pond will be cleaned. Topsoil Nearly all surface disturbance activities at the RAG Empire operation have been completed. In isolated instances where surface disturbance may occur, all available A and B soil horizons will be salvaged as one product due to the small acreages involved. In areas where minor disturbances occur involving light [nick or other equipment usage, topsoil may not be removed if gathering of the topsoil would create a greater disturbance than the disturbance itself. In areas subjected to occasional traffic, the ground will be scarified and planted according to the approved seed mixture presented in Section 2.05.4 Reclamation Plan. In the event surface disturbance is required, topsoil will be salvaged according to the following plan: • Identification of area in which topsoil salvage operations are to occur, either through flagging of area or verbal description of area to supervisor. • Determination of depth to which topsoil will be salvaged (topsoil salvage depths have been determined through a report by Jim Walsh that is presented in Exhibit 13, Soil Inventory-Mine Facilities, Disposal Site, and Pit 6 and 7 Areas). • Topsoil is then removed. tf possible, topsoil will be directly redistributed over a re-graded area as opposed to long-term stockpiling. All topsoil stockpiles will be stabilized with a perennial seed mixture. The perennial seed mixture is presented in Table 57, Topsoil Stockpile Seed Mixture. All topsoil stockpile locations are shown on the Drainage and Sediment Control Map (Map 26). The following tables indicate the topsoil stockpile locations, the volume of topsoil stored, and the topsoil replacement areas and depth to which topsoil will be replaced: Table 58, Topsoil Replacement - No. 5 Portal and General Area Table 59, Topsoil Replacement - No. SA Portal and General Area, Old Shop, Carpenter Shop Table 60, Topsoil Replacement - No. 9 Portal and General Area, Waste Disposal Pile Table 61, Topsoil Replacement - No. 9A Portal Area Table 62, Topsoil Replacement -Miscellaneous Sites at Mine Overburden Since RAG Empire is an underground mining operation, there is very little movement of overburden. Previous limited surface mining activity is now abandoned and currently undergoing reclamation. Refer to Section 2.05.4 Reclamation Plan for reclamation details. Coal Handling Structures • A detailed discussion of the coal handling structures utilized at RAG Empire has been discussed previously in the Facilities portion of this Section.
