Construction Summary <br /> Many maintenance tasks were accomplished during the course of the construction season at Coal Basin under this <br /> contract. <br /> Roads B, C, D were reclaimed during the 2000 construction season. Observation of these roads following the 2001 <br /> snowmelt indicated that additional drainage control structures were needed on Roads B and D. Also, some of the <br /> existing drainage structures were in need of upgrading to accommodate actual flows. This repair and construction <br /> work was accomplished under the Spring Maintenance Contract. <br /> Ditch 8, located at the south easterly margin of the Sutey Refuse Disposal Area, required additional energy dissipating <br /> structures. These had been purchased in the fall of 2000. These structures, known as Georidge, were installed in the <br /> spring of 2001. <br /> Observation indicated that the Bear Creek Project area required minor erosion control maintenance. This was <br /> accomplished using hand labor to choke gullies full of straw in order to reduce runoff velocities. <br /> Silt fence was erected in various areas as required by the Storm Water Permits that the Division holds at the Coal <br /> Basin Mine. <br /> Miscellaneous junk, debris and trash was removed from the site, and hauled to the dump for disposal. <br /> Roads B, C, D were re-seeded in the fall of 2001. <br /> Small earth moving tasks, such as road-side ditch maintenance, maintenance of Ditch 1 at the west side of the Sutey <br /> Pile, and contouring of a portion of the east side of the Facilities area was accomplished. <br /> V. FUTURE MAINTENANCE <br /> The entire permit area needs to be monitored at least three times per year: after spring runoff, in early August <br /> following the beginning of the monsoon season, and in early September, following the end of summer rains. <br /> VI. SUMMARY <br /> This Contract was used to accomplish a number of miscellaneous reclamation and maintenance tasks at the Coal <br /> Basin Mine. A similar contract should be awarded each year when no other large-scale Projects are scheduled, in <br /> Drder to accommodate the maintenance needs of this formerly permitted mine. <br /> Project Manager: Steve Renner <br /> Date: November 26, 2001 <br /> b:\closeout.form <br />
