F. The Contractor shall coordinate temporary water pollution, erosion, and sedimentation control work with the permanent drainage, sedimentation, and erosion control work that may be specified in the Contract to ensure continuous water pollution, erosion, and sedimentation control is maintained during performance of the Work.

G. If the Contracting Agency orders the Work suspended for an extended time, the Contractor shall make, before the Contracting Agency assumes maintenance responsibility, every effort to control erosion, pollution, sedimentation, and runoff during shutdown.

H. The extent of excavation, borrow, and embankment operations in progress will be limited commensurate with the Contractor’s capability and progress in keeping the finish grading, mulching, seeding, and other permanent pollution, erosion, and sedimentation control measures current according to the accepted critical path schedule. If the Project Manager determines that water pollution or erosion or sedimentation could occur due to seasonal limitations, the nature of the material, or the Contractor’s progress, temporary water pollution, erosion, and sedimentation control measures shall be taken immediately. The Project Manager may require the Contractor’s operations to be scheduled so those permanent pollution, erosion, and sedimentation control features will be installed concurrently with or immediately following grading operations.

I. Under no conditions shall the amount of surface area of erodible earth material exposed at one time by clearing and grubbing, excavation, borrow, or fill within the right of way exceed 18,000 square feet without prior approval by the Project Manager.

J. Permanent pollution, erosion, and sedimentation control work ordered by the Project Manager and not covered in the Bid will be considered extra work and paid for as such. Only pollution, erosion, and sedimentation control included in the Bid Form or designated by the Project Manager and ordered as extra work will be considered permanent control measures.

K. Temporary erosion control, temporary sedimentation control, and temporary water pollution control shall be the Contractor’s responsibility. Costs for temporary erosion control, for temporary sedimentation control, and for temporary water pollution control work will be considered incidental to the Work and such costs shall be included in the Lump Sum Bid.

L. Records of submitted and actual pollution, erosion, and sedimentation controls and plans shall be retained for a period of 3 years after the Completion Date and shall be available at reasonable times and places for inspection by the Project Manager and, when applicable, other entities providing funds for the Work.
