Correct use of redundant (2) forms of perimeter control (silt fences) when working within 50 ft from the waterbody while using a native vegetated buffer to also capture sediment runoff. (If waterbody is an impaired water then vegetated buffer must be at least 100 ft long with no work occurring in the buffer)
