4.0 DISTURBED AREA REGRADING <br />4.1 Description <br />This specification covers all work required for excavation and fill necessary <br />to complete the regrading scheme as shown on the exhibits, for compacting fill <br />material, for removal and disposal of mining related materials encountered in <br />the excavations, for special handling of coal and coal waste material existing <br />on the surface and encountered in the excavations, and for ripping portions of <br />final regraded surfaces to alleviate surficial compaction. <br />4.2 Execution <br />A. Classification of Excavated Materials <br />Earth materials to be excavated from cut areas and placed within fill <br />areas consist of non-coal material and coal/coal waste material, The <br />coal material consists of the remains of the coal stockpile, coal <br />spillage along the ground surface beneath the coal conveyors, and <br />coal spillage over the embankments of the coal stockpile area. Coal <br />waste consists of coal material which has oxidized or degraded over <br />time due to prolonged exposure to the elements. The coal/coal waste <br />material is easily distinguished from the non-coal material by marked <br />differences in color and consistency. Unless otherwise directed by <br />the PROJECT MANAGER, excavation shall be performed to the lines and <br />grades shown on the drawings and as described in these specifications <br />regardless of the nature of materials encountered. No additional <br />allowance above the price bid will be made on account of any of the <br />material being wet or frozen, or additional work required to remove <br />and dispose of coal/coal waste material, large rocks and boulders, <br />subsurface utilities, and mining related features encountered within <br />excavated areas. The CONTRACTOR shall assume all responsibility for <br />deductions and conclusions as to the nature of the materials to be <br />excavated, the difficulties of making and maintaining the required <br />excavations, and the presence and extent of coal/coal waste material, <br />large rocks and boulders, subsurface utilities, and mining related <br />features within areas to be excavated. The OWNER does not represent <br />that the excavation can be performed or maintained at the lines <br />described in these specifications or as shown on the drawings. <br />-20- <br />
