Each of these roads <br /> has been previously reclaimed. Access to the work areas will be restricted to a maximurn <br /> eight feet(S')wide two wheel track that Contractor will establish at each road. All Traffic <br /> must be restricted to the two wheel track. It is estimated that up to ten (10) acres of <br /> previously reclaimed roadway may require rehabilitation. <br /> Project Manager will require that any and all previously reclaimed road surfaces <br /> compacted by reclamation access activities as a result of this Project will be subject to the <br /> requirements of this revised task. <br /> Following completion of all work tasks requiring motorized access across a road, <br /> Contractor will accomplish road reclamation rehabilitation. Rehabilitation will be <br /> accomplished by dozer ripping the access track and any other disturbances as directed by <br /> Project Manager, and reconstruction of all low water crossings and water bars located on <br /> the road as directed by Project Manager. Ripping will occur so that dozer rippers, spaced <br /> no further apart than two feet(2') are sunk ten inches (1011)into the ground. The areas <br /> will be ripped in a discontinuous manner so that compacted areas are heavily scarified. <br /> Low water crossings and water bars will be re-constructed to their pre-project <br /> dimensions. <br /> Following ripping and water bar/low water crossing reconstruction,the areas affected by <br /> these activities will be revegetated. It is estimated that approximately ten (10) acres will <br /> be dozer scarified and revegetated as part of the road rehabilitation Task_ Contractor will <br /> supply all materials (excepting seed),labor and equipment necessary and incidental to <br /> completing this Task. <br /> Revegetation will occur in the following manner: <br /> Seed <br /> The Owner will provide seed. Contractor must give the Project Manager at least fifteen <br /> (15)working days notice of the acreage to be seeded, so that the proper amount of seed i <br /> delivered. Hand written acreage calculations are acceptable. All areas will be seeded <br /> with the "Coal Basin Mine Site Seed Mixture", (Table 2)_ It is anticipated that the seed <br /> will be broadcast applied to the road surfaces at the rate specified in Table 2_ <br /> Fertilizer <br /> Commercial fertilizer is required for this Task, and will be supplied by Contractor. It is <br /> anticipated that the fertilizer will be broadcast applied to the road surfaces. <br /> Mulch <br /> Mulching is required for this project. Mulch will be provided by Contractor, and must <br /> conform to Section 20.2 of the General Specifications. All mulch must be certified as <br />
