<br />operations was routed through settling ponds prior to being discharged from the site. These <br />ponds and the respective discharge points were permitted by the mine operator, Mid-Continent <br />Resources through the Water Quality Control Division. The contributing area of nearly all of the <br />ponds has been reclaimed by Minerals and Geology since 1995. The only pond contributing <br />areas, which are still subject to reclamation, aze those located near the confluence of Coal and <br />Dutch creeks. Reclamation construction in this area is addressed in the Storm Water <br />Management Plan submitted by Minerals and Geology in November, 1998. <br />Final disposition of the ponds was addressed in the reclamation plan submitted by Mid-Continent <br />Resources to the Mined Land Reclamation Division (now the Division of Minerals and Geology). <br />The original reclamation plan stated that the ponds would be dewatered and the embankments <br />were to be pushed into the pond depression. The graded surface would then be revegetated. The <br />plan did not discuss how water flow from up-gradient areas would be routed through the <br />reclaimed pond areas, or how storm water from the reclaimed ponds would be treated prior to <br />vegetation becoming established. <br />The Division has expressed the idea that the ponds, if left in place, could become useful wildlife <br />habitat if appropriate modifications were made to the discharge structures. The establishment of <br />wetlands species at the margins of the ponds is also component of the modified reclamation plan. <br />The private property land owners and the U. S. Forest Service have both agreed with this <br />proposal. <br />DESCRIPTION OF ACTIVITIES <br />The Coal Basin Mines are located within the Coal Creek watershed. The other major drainage <br />within Coal Basin, Dutch Creek, is confluent with Coal Creek approximately four miles above the <br />Crystal River and Redstone in western Pitkin County. Redstone is located on Highway 133, <br />approximately 18 miles south of Cazbondale. The area is located at elevations of between <br />approximately 8,300 feet and 10,000 feet. Reclamation operations conducted by the Division at <br />the Coal Basin Mine are geared toward returning mining related disturbances to a condition <br />capable of supporting the pre-determined post mining land uses of grazing, wildlife habitat and <br />limited recreation. An important factor in meeting these goals is the reduction of sediment <br />contribution from disturbed areas to receiving streams. In order to meet the goal of sediment <br />reduction, substantial earth moving is necessary, as are revegetation processes. <br />This Storm Water Management Plan addresses treatment of stormwater, which is contributed to <br />the ponds and the adjacent construction zone at each pond to be reclaimed. A complete <br />tabulation of the ponds subject to this Storm Water Management Plan is attached. <br />Each pond, or in some cases pond series, maybe thought of as individual work sites, as the ponds <br />are generally separated by great distances. The reclamation construction activities to be <br />conducted at each pond is essentially the same, however. A description of the reclamation tasks <br />to be accomplished at each pond follows. <br />Pond Reclamation Description <br />
