Dewatering shall comply with the following:
- (a) The discharge shall be stopped immediately if the receiving area shows any sign of instability or erosion;
- (b) All channels, swales, and ditches dug for discharging water from the excavated area shall be stable prior to directing discharge to them;
- (c) If a construction equipment bucket is used, it shall empty the material to a stable area;
- (d) No dewatering shall occur during periods of intense, heavy rain;
- (e) Flow to the sediment removal structure shall not exceed the structure’s capacity to settle and filter flow or its volume capacity; and
- (f) Wherever possible, the discharge from the sediment removal structure shall drain to a well-vegetated buffer by sheet flow while maximizing the distance to the nearest water resource and minimizing the slope of the buffer area.
