Sediment Control, Road E Culvert Removal <br /> CONTRACTOR shall properly install either silt fence or straw bales (see Figures and ) at <br /> the base of the work area adjacent to the North Fork of Dutch Creek in order to minimize the <br /> amount of dirt which is lost into the creek. This will be accomplished and paid as a part of Task <br /> 3, Culvert Removal, and is not included as part of Task 11, Post Construction Sediment Control. <br /> Straw bales, if selected for use as sediment control, must be certified as weed free or weed seed <br /> free (see the requirements of Task 10, Revegetation) shall be placed adjacent to each stream at <br /> the base of each side slope created during performance of this Task. A trench measuring four <br /> inches (4") deep, by the width of the bales, by the length of the side slope cuts shall be <br /> excavated at the base of each side slope cut. The base of the trench shall be smooth and free <br /> of large rock so that the bales may be placed in direct contact with the ground surface. Each <br /> bale shall be anchored using two wood stakes per bale. The bales shall be placed so that any <br /> one bale is in direct contact with the adjacent bale (s). Silt fence, if selected for use as sediment <br /> control, shall be installed as per Figure <br /> Both Work Areas <br /> All culvert materials or scrap encountered shall be collected and transported from the mine site <br /> for disposal by CONTRACTOR. Extracted culverts may be temporarily stockpiled near the main <br /> gate to the Coal Basin Mine. All extracted culverts must be removed from the site prior to <br /> submitting for payment upon completion of this task. <br /> Measurement and Payment <br /> Payment for completion of this task will be per culvert removed. The number and location of the <br /> culverts to be removed will be established by PROJECT MANAGER prior to this Task being <br /> initiated. Payment for removal of the culverts will be made at the unit price established in Item 3 <br /> of the Bid Schedule. Such payment will be considered full compensation for all equipment and <br /> labor needed to accomplish removal of the designated culverts, including backfilling and <br /> compaction of the excavations. Payment shall be as this task is completed and approved by the <br /> PROJECT MANAGER. <br /> TASK 4 ROAD GRADING <br /> Four road segments located near the north western portion of the Project Area require grading in <br /> order to promote the desired post reclamation drainage pattern. Because some of the roads <br /> have differing post-reclamation uses, the roads will be graded to different conditions. Three <br /> roads will be backfilled, while one will be sloped and ripped. See Map 3, Project Area, for the <br /> locations of these road segments. <br /> Sutey Access and Belt Line Transfer Roads <br /> Road segment lengths are estimated to be 1,850 feet at the Upper Sutey access road, 1,900 feet <br /> at the Lower Sutey access road, 450 feet at the beltline transfer road. NOTE that this portion of <br /> Task 4 must be accomplished in conjunction with Task 3, Culvert Removal. <br /> These roads will be backfilled and graded so that the original contour of each area is <br /> approximated. Material shall be excavated from the outslope of the roads and placed onto the <br /> roadway in order to blend the hill slopes above and below the road segments. The outslope <br /> excavation must not create a slope steeper than the naturally occurring hill side at the point of <br /> excavation. Material placed on the roadway must be compacted in two foot (2') lifts. The fill <br /> 11 <br />
