MLRD Page 2 <br /> Supplemental Information <br /> from the hydroclone/recycle sump is flocculated and then <br /> reports to the 020 pond for "finishing" (i.e. settling of <br /> fine solids) prior to discharge to Coal Creek at Outfall <br /> 020. Underflow goes to the coal preparation plant (i.e. <br /> sump and/or thickener and/or plant refuse filter) , then <br /> through the normal plant cycle, wherein coal solids are <br /> separated from non-coal refuse and the refuse is conveyed <br /> to the approved refuse disposal area. <br /> Underflow to 001 Ponds: All mine water reports to the water <br /> treatment plant. Overflow goes to 020 pond for "finishing. " <br /> Underflow goes to 001 ponds, is removed in normal pond <br /> cleaning. <br /> Overflow to 001 Ponds: All mine water reports to the water <br /> treatment plant. Overflow goes to 001 ponds for "finishing. " <br /> Underflow to coal preparation plant cycle. <br /> Split Flow: Flows are divided between the 016 ponds and the <br /> water treatment plant. The plant design capacity of up to <br /> 1,000 gpm, combined with the 016 pond capacity (1,500 gpm) <br /> allow for a combined treatment capability of up to 2,500 gpm. <br /> Note: Attachment A, Process Flow Diagram; <br /> Attachment B, Process Flow Description; <br /> Attachment C, Certification of Calculations; <br /> Attachment D, Calculations for 020 Pond; <br /> Attachment E, Calculations for 001 Ponds and <br /> Ditch. <br /> In addition, Mid-Continent requests permission to proceed with <br /> modifications to the 020 pond. These include: <br /> Installation of underflow trash rack to <br /> prevent escape of floating solids. <br /> (Attachment F) <br /> Installation of a stilling plate across the <br /> pond to slow flows and enhance settling of <br /> solids.
