During construction, which perimeter protection measure is recommended to prevent sediment discharge?

• A. A chain-link fence
• B. No perimeter protection is necessary
• C. Super silt fence, chain-link fence, or other measures to prevent sediment discharge
• D. Temporary lighting should be installed

Answer: (B)

Protecting the site perimeter with sediment controls is essential to keep sediment from leaving the construction area. Implementing a perimeter measure like a super silt fence along the site boundary creates a barrier that traps sediment in runoff while allowing water to infiltrate or drain away, significantly reducing the chance of sediment discharge off-site. Other acceptable perimeter approaches can include equivalent sediment-control devices or methods that accomplish the same goal of stopping or slowing sediment-laden runoff at the boundary. Options that don’t address sediment control, such as just a basic fence or temporary lighting, do not prevent sediment from escaping the site. Saying no perimeter protection is necessary contradicts standard practices aimed at preventing erosion and protecting receiving waters.
