Ditch 8 is a long, steep drainage ditch located at the south <br /> easterly most margin of the Sutey Refuse Disposal Area. This drainage channel did not <br /> function as designed, so it was rebuilt in 2000. The channel was widened, and a double <br /> layered soil retention system designed to hold soil in place at high water velocities was <br /> installed. Energy dissipation structures and other water diversions were installed as well. <br /> The area was privately owned, but has since been transferred to public ownership. <br /> Pond Reclamation. This project was designed to transform the sediment ponds on <br /> private and public lands throughout the mine into maintenance-free water retention <br /> structures, while providing benefits to wildlife and other area values. All ponds at the <br /> site, excepting those that treat the mine water discharge (016 pond system) were subject <br /> to this project. <br /> All of the sediment retention ponds in Coal Basin had been regulated by the Colorado <br /> Water Quality Control Division under a National Pollution Discharge Elimination System <br /> (NPDES) permit held by Mid Continent Resources. By 2000, the contributing areas to <br /> the ponds had been substantially reclaimed, thus sediment contribution to the ponds was <br /> minimal. Prior to project implementation, the Colorado Water Quality Control Division <br /> terminated the NPDES permit for all but the 016 ponds. In order to facilitate NPDES <br /> permit termination, and thus project initiation, DRMS applied for and received a Storm <br /> Water permit that covered each of the ponds to be affected by the project. This permit <br /> was eventually terminated in 2005. The 016 ponds NPDES permit was terminated at the <br /> request of Mid Continent Resources under a separate action at a later date. <br /> The project entailed removal of the corrugated metal pipe (CMP) discharge structures, <br /> reducing the slope in the pond embankment caused by CMP removal, and lining of the <br /> excavation with rock rip rap. All affected areas were planted at the water line elevation <br /> with a wetlands seed mixture and willows. Areas above the water line were planted with <br /> an appropriate upland seed mixture. <br /> 16 <br />
