In the case of the 009 pond, the corrugated metal spillway was removed and replaced by <br />a rock lined channel. The corrugated metal dewatering device was removed from the <br />embankment and the sides of the excavation were graded to a 2 H : 1 V or shallower. <br />The base of the excavation was well armored with native rock rip rap and the excavation <br />sides were fertilized, seeded and mulched. There was no discharge from the pond during <br />construction due to the low water elevation at the time. <br />The 009 pond discharges to a second, lower pond which is located east of, and adjacent <br />to, the former location of the Dutch Creek Flume. During active operations, this pond <br />was dewatered directly into the Dutch Creek Flume by a pair of small Poly Vinyl <br />Chloride pipes. Because the Dutch Creek Flume was eliminated in 1999, an alternative <br />drainage had to be constructed to convey the outflow to Coal Creek. The PVC pipes <br />were filled with non-shrink grout in order to eliminate drainage toward the old flume <br />location. A new channel was constructed from the north end of this pond for a distance <br />of about three hundred feet. This channel was lined with C-125 aspen fiber mat, to <br />provide for erosion control. Because the channel loses elevation quickly over the <br />northern most fifty feet, and because of the extreme erodability of the underlying <br />material, a design for the final seventy five feet or so of the channel had to be <br />implemented. A channel was constructed using straw bales for the base and sides. These <br />bales were anchored by excavating the ground, placing and staking the bales :in place, and <br />then backfilling around them. The C-125 mat was extended over the top of this structure. <br />This channel will be monitored during 2000 in order to determine its effectiveness in <br />conveying the runoff to Coal Creek. Modifications, if necessary, will be made at that <br />time. <br />The 001 pond system is a series of four settling ponds located adjacent to Coal Creek <br />below the mine facilities area. This pond system treated stormwater effluent derived <br />from the former mine facilities area. As discussed in our 1998 annual report for <br />Stormwater permit COR040204, reclamation construction at that time bifurcated the <br />contributing area to these ponds, so that drainage from only the eastern half of the mine <br />facilities area reported to the 001 ponds. <br />The portion of the mine facilities area located east of the Dutch Creek Diversion was <br />reclaimed in 1999. Reclamation of this area has eliminated the need to maintain the 001 <br />inlet ditch and pond system. Further, completion of the Bear Creek reclamation project, <br />located near the eastern margin of the Old Refuse Pile, and immediately adjacent to both <br />the 001 pond inlet ditch and the upper two 001 ponds, required that the inlet ditch be <br />eliminated and that the upper most 001 pond be filled with earthen materials. <br />The only water which the ditch conveys is ground water which discharges to the ditch in <br />the form of springs and seeps. The flow of the inlet ditch was diverted into Coal Creek <br />about one half mile below the confluence of Coal and Dutch Creeks. The small amount <br />of flow in the ditch passes through passive treatment systems prior to reaching Coal <br />Creek. Near its point of diversion, the water passes through a gravel blanket, then flows <br />through a woven mat constructed of aspen fibers and ultra violet resistant netting. After <br />4
