NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) January 1, 2026 Volume 2 Sediment controls shall be installed prior to performing grubbing, excavation, and borrow or fill operations, except for those actions necessary to install the sediment controls. The Contractor shall limit the area of clearing and grubbing, excavation, borrow and embankment operations in progress commensurate with their capability to minimize erosion and sediment transport and keep the finish grading, mulching, seeding and other temporary and/or permanent control measures current in accordance with the approved schedule. The Engineer may determine that a potential for erosion or sediment transport exists and direct the Contractor to install temporary erosion controls earlier. When permanent soil erosion and sediment control measures cannot be installed due to seasonal or other limitations, temporary soil erosion and sediment control measures shall be installed. Prior to removing or disturbing any erosion or sediment control measure that may be required to be reestablished due to continual grading operations, the Contractor shall verify the proposed progression of operations and the reestablishment of control measures with the Engineer to ensure the continuity of erosion and sediment control. Sediment control measures shall not be removed without the Engineer’s approval.
A.Inspection and Maintenance. Soil erosion and sediment control measures shall be inspected and maintained by the Contractor for the duration of the contract, including winter shutdown, etc. Inspection and maintenance shall continue until after the permanent stabilization measures are established and the temporary control measures are removed. The remaining disturbed area shall be permanently stabilized in accordance with the contract documents. All temporary controls shall be inspected by the Contractor at least every seven calendar days and after each runoff event to determine if the practice is functioning as intended. All inspections shall be completed within one calendar day. Within 1 work day from completion of the inspection, the Contractor shall:
1.Repair or rebuild the practice to function as originally intended.
2.Remove sediment deposition which reaches one half the height of the practice. All sediment removed during maintenance of the practice shall be considered unsuitable material and disposed of in accordance with §203-3.01E Unsuitable Material. Material shall be disposed of away from sensitive resources including wetlands, water courses or other bodies of water. Where erosion control materials have been used on final grades that have been permanently seeded, the Contractor shall care for the areas until acceptance of the Contract or acceptance of the turf, whichever is later. Where necessary, such care may include, but is not limited to providing warning signs or barricades for protection against traffic. In addition to routine maintenance, any surface that has settled, become gullied, or otherwise damaged due to the Contractor’s operations shall be repaired at no additional expense to the state to reestablish the grade and soil conditions that existed prior to placing erosion control materials.
