the last inspection and water levels are now some 8-10 feet below the lowest discharge point. <br /> Drainage at the RDA appeared functional in accordance with the approved design. Clean water <br /> diversion ditch D26 behind the coal silos should be restored to the original design condition <br /> after powerline construction has modified two short portions of this ditch. <br /> Support Facilities <br /> Additional work continues on support facilities as approved under TR-56. Hoist foundations are <br /> nearly complete. The operator should immediately consider appropriate locations for materials <br /> storage, as continued storage on the raw coal stockpile area will not be acceptable long-tens. <br /> Mine Materials <br /> r� <br /> Hoist foundations <br /> t" <br /> Topsoil <br /> Please ensure that all stored topsoil is properly marked in accordance with Rule 4.02.7. <br /> Specifically, topsoil temporarily stored at the rock dust tank area under construction requires <br /> markers to prevent inadvertent loss or contamination with subsoil and bedrock material. <br /> Processing Waste <br /> The refuse disposal area has not changed significantly although it appears likely that refuse <br /> material will soon be added in significant volumes once the prep plant begins serious <br /> operations. The current configuration at the top of the refuse conveyor is insufficient to handle <br /> large delivery rates of refuse that may occur. Currently, the working area below the conveyor is <br /> very small, steep, and immediately adjacent to the RDA west downdrain. Extension of the <br /> conveyor may be the temporary option until permitting of another option can be completed. <br /> 4 <br />
