A copy of the attendance list is <br /> attached. Please note the following clarifications and amendments to the Coal Basin/Sutey Ditch 8 <br /> Reconstruction Project Invitation and Bid: <br /> 1. Task 2 Ditch 8 Reconstruction; The existing liner in the old Ditch 8 may be left in place. <br /> 2. Task 2 Ditch 8 Reconstruction; The old ditch, and any gullies or flat areas between the old ditch <br /> and the Sutey Refuse Pile, shall be filled with either topsoil or dirt excavated from the New Ditch 8 <br /> so that a slope is created from the eastern margin (or edge) of the Sutey Refuse Pile sloping <br /> eastward to the western crest of the newly constructed Ditch 8. If dirt from the excavation of the <br /> New Ditch 8 is used, this material will be covered by topsoil as specified in Task 4, Adjacent Area <br /> Topsoil Application, except that only six inches (6") of topsoil need be applied to the area west of <br /> the New Ditch 8, and that this area would not be ripped prior to topsoil application. NOTE that the <br /> Bid Specifications require a minimum fill depth of one foot (1') above the adjacent ground surface <br /> at the old ditch 8. For purposes of clarification, adjacent ground surface is defined as that ground <br /> surface immediately east of the old ditch 8. <br /> 3. Task 2 Ditch 8 Reconstruction; PROJECT MANAGER will stake the base and upper extent of <br /> the New Ditch 8 prior to construction beginning. An approximate grade change location will also be <br /> staked where the slope sharply breaks near the upper-most portion of the New Ditch 8. <br /> CONTRACTOR will construct the New Ditch 8 to the specifications outlined in the Invitation and <br /> Bid. The minimum specified widths and depths must be carried throughout the length of the <br /> channel. <br /> 4. Task 2 Ditch 8 Reconstruction; CONTRACTOR is primarily responsible for checking the grade, <br /> depth and width of the ditch as it is being constructed. PROJECT MANAGER will periodically <br /> verify that the specified width and depths are being met. <br />
