linear feet of four strand barbed wire fence was constructed for a cost of$1,928.50. <br /> The fence will remain in place until vegetation becomes well established in this area. <br /> Spring Maintenance <br /> Maintenance in 2001 primarily focused on accomplishing repairs and additional <br /> drainage dip construction and maintenance on Roads B and D. Additional drainage <br /> dips were constructed at locations selected and marked in the field. Other dips were <br /> rebuilt or widened as need dictated. At the lower most portion of Road B, a drainage <br /> trench was dug adjacent to the cut slope of the road. This was necessary in order to <br /> drain a long, seasonal seep area which discharged directly onto the backfill in this area. <br /> Other maintenance tasks completed included installing additional energy dissipation <br /> structures in Sutey Ditch 8, which drains the eastern portion of the Sutey Refuse <br /> Disposal Area, and road side ditch maintenance in the vicinity of the Sutey Refuse <br /> Disposal Area. Miscellaneous junk and scrap was collected from the site and disposed <br /> of, and some previously reclaimed areas were inter-seeded. <br /> This Project was also utilized to maintain compliance with the two Stormwater permits <br /> that the Division holds at Coal Basin. Erosion control work was accomplished on the <br /> Bear Creek Project Area, and silt fence was either repaired or erected in other areas as <br /> needed. <br /> The Contractor expended about sixty two hours of manpower and equipment time on <br /> the site, for a total cost of$3,721. <br /> Flume Area Project <br /> The Dutch Creek Flume was demolished as part of on-going reclamation in 1999. The <br /> slope located behind and on either side of the flume structure was over-steepened due <br /> to headward erosional processes which were active during the life of the flume. The <br /> purpose of the Flume Area Project was to create a productive landform which does not <br /> pose a hazard to users of the area. <br /> A coarse rock underdrain was constructed under the footprint of the fill area. Three feet <br /> of locally derived coarse rock was placed under a geotextile fabric. The coarse rock <br /> was also placed against the southeast portion of the existing cut slope, as it exhibited <br /> seasonal springs and seeps. The underdrain allows near surface ground water to flow <br /> under the fill materials directly to Coal Creek without saturating the fill. <br /> Material was then cut from the existing slopes and compacted in horizontal lifts as the <br /> fill was constructed toward the cut and fill match line. The cut and fill slopes measured <br /> about 2.5H : 1V when completed. Following completion of cut and fill operations, topsoil <br /> was added over all disturbed areas to an eight inch depth. The soil was covered by two <br /> tons per acre of certified weed free straw mulch, and then the entire surface of the cut <br /> and fill was severely scarified using a trackhoe. The trackhoe created hundreds of dips <br /> in the soil surface, and worked the mulch into the soil and underlying cut and fill <br /> material. Following completion of earth work activities, the area was fertilized and <br /> 5 <br />
