(2) <br />within the disposal area was movers as well as 6-12" of topsoil north of the <br />stockpile where Oak brush was ilPared. Two topsoil stockpiles were estab- <br />lished, see diagram 1 Cor the general location of these stockpiles. As the <br />dirt cover is placed over the coal waste, this topsoil will be used on the top <br />6-12" as far as it goes. The majority of the disposal area was previously dis- <br />turbed with only a small topsoil stockpile to show for it. <br />The surface drainage alterations began 9-26-84 when a new drain location <br />was dug in the ail pond. An 8" class 200 PVC pipe was installed in the trench <br />below the design level of the bottom of the water storage. A gas compactor <br />was used [o recompact dirt in the trench. <br />Cement was mixed and placed around the pipe near the middle of the em- <br />bankment to act as a water cutoff. An elbow and screw-down plug were installed <br /> to permit drainage of storage rights out oC the pond. Another 8" pipe was <br /> installed higher in the embankment for the primary spillway and dewatering device. <br /> Alter the two pipes wcrcinstailed, work began to build up the pond embankment <br />to the 6340' elevation. The emergency spillway was dug 1-21-85 but has not <br />been rip-rapped. The water level is being kept near the bottom of the <br />water storage level to reduce tl~e saturation in the toe of the new bench and <br />to allow recovery of dirt pushed into the pond during the toe excavation. <br />The work remalning for final certification oC this pond is: to adjust ele- <br />vations o~ primary spillway and the dewatering device, and to rip-rap the emer- <br />gency spillway. <br />The draw north o~ the bench was started 10-4-84 and continued off and on <br />through mid-December when large rip-rap was placed in the steep portion of <br />the draw. Pit run gravel approximately 8" and under was placed in the other <br />portion of the drain. This draw has been completed. <br />• Excavation of. the t'oe to stable material began 9-26-84.
