Erosion and sediment control measures should be maintained until all disturbed ground has been permanently stabilized and surface water run-off is clear. Erosion and sediment controls may be inspected by the Environmental Surveillance officer 4.8.3) Exposed soils along the project site should be stabilized as quickly as possible with fast germinating cover crop seed following construction to prevent erosion. 4.8.4) All dewatering should be treated and released to the environment at least 30 meters from a watercourse and allowed to drain through a well-vegetated area for filtration. No dewatering effluent should be sent directly to any watercourse, wetland, or forest, or allowed to drain onto disturbed soils within the work area to avoid releasing sediment-laden water directly into the environment. 4.8.5) Remove temporary erosion and sediment control products, especially non-biodegradable materials, when they are no longer required.
