1 If the water exceeds the effluent limitations requirements of the <br />NPDES permit, Peabody will retain the water within the permit area <br />until it meets effluent limitations requirements by one or a <br />combination of the following techniques: <br />1. Pump the water to another sedimentation pond. <br />2. Evaporation. <br />3. Utilize the water for dust control within the permit <br />area. <br />4. Utilize the water for sprinkler irrigation on the <br />reclamation areas to increase the soil moisture. <br />5. Reduce the discharge rate and/or install dentention <br />structures such as silt fence or hay bales at the <br />discharge location. <br />Whether the pond is bypassed or the water is moved away from the <br />construction area to other areas of the permit area, Peabody will <br />minimize erosion and comply with the applicable regulations. <br />,• ~ Embankment reconstruction will be conducted in compliance with CMLRD <br />regulations (see Exhibit 13-15). The existing embankment will be <br />cleared of all organic matter prior to the placement of new fill <br />material. The placing and spreading of fill material will proceed from <br />the lowest point on the embankment in horizontal layers of such <br />thickness as to allow for a minimum compaction of 93 percent of the <br />standard proctor. Fill material will be free of sod, large roots, <br />vegetation matter, coal or coal processing waste, and frozen material. <br />• Both the upstream and downstream slopes of the embankment will be 3h:ly <br />or flatter. The completed embankment and surrounding disturbed areas <br />will be seeded and revegetated to prevent erosion in accordance with <br />applicable regulations. The 005 East Ditch and West Ditch will be <br />constructed to divert all runoff from the existing reclaimed area into <br />Pond No. 005. <br /> <br />15 <br />
