SECTION 3125 00 <br /> EROSION AND SEDIMENTATION CONTROLS <br /> PART 1-GENERAL <br /> 1.01 TEMPORARY CONTROL OF AIR/WATER POLLUTION AND SOIL EROSION/SILTATION <br /> A. This item shall consist of temporary control measures as shown on Plans or as ordered by Engineer during <br /> construction to control water pollution, soil erosion, and siltation through use of temporary rock construction <br /> entrance,berms,dikes, dams, sediment basins, silt fences, gravel, mulches, grasses, slope protection, and other <br /> erosion control devices or methods. <br /> B. Temporary erosion control measures contained herein shall be coordinated with permanent erosion control <br /> measures specified as part of this Contract to extent practical to assure economical, effective, and continuous <br /> erosion control throughout Project construction period. <br /> C. Temporary control may include Work outside construction limits such as borrow pit operations, equipment and <br /> material storage sites,waste areas,and temporary plant sites. <br /> 1.02 AUTHORITY OF ENGINEER: <br /> A. Engineer has authority to limit surface area of erodible earth material exposed by clearing and grubbing,to limit <br /> surface area of erodible earth material exposed by excavation, borrow and fill operations, and to direct <br /> Contractor to provide immediate permanent or temporary pollution control measures to minimize contamination <br /> of adjacent streams or other watercourses,lakes,ponds,or other areas of water impoundment. <br /> 1.03 CONSTRUCTION DETAILS: <br /> A. Contractor will be required to incorporate all permanent erosion control features into Project at earliest <br /> practicable time as outlined in accepted schedule. <br /> B. Except where future construction operations will damage slopes, Contractor shall perform permanent seeding <br /> and mulching and other specified slope protection work in stages,as soon as substantial areas of exposed slopes <br /> can be made available. <br /> C. Temporary erosion and pollution control measures will be used to correct conditions that develop during <br /> construction that were not foreseen during the design stage; that are needed prior to installation of permanent <br /> control features; or that are needed temporarily to control erosion that develops during normal construction <br /> practices,but are not associated with permanent control features on Project. <br /> D. Where erosion is likely to be a problem, clearing and grubbing operations should be scheduled and performed <br /> so that grading operations and permanent erosion control features can follow immediately thereafter if Project <br /> conditions permit; otherwise, temporary erosion control measures may be required between successive <br /> construction stages. <br /> E. Engineer will limit area of clearing and grubbing,excavation,borrow, and embankment operations in progress, <br /> commensurate with Contractor's capability and progress in keeping finish grading,mulching,seeding,and other <br /> such permanent control measures current in accordance with accepted schedule. Should seasonal limitations <br /> make such coordination unrealistic, temporary erosion control measures shall be taken immediately to extent <br /> feasible and justified. <br /> F. If temporary erosion and pollution control measures are required due to Contractor's negligence,carelessness,or <br /> failure to install permanent controls as a part of Work as scheduled or are ordered by Engineer, such work shall <br /> be performed by Contractor at Contractor's own expense. <br /> Division 31—Earthwork <br /> DV31fi <br />
