      (28)   Sediment Basin: A barrier or other suitable retention structure built across an area of water flow to intercept run-off and allow transported sediment to settle and be retained, prior to discharge into waters of the State.
      (29)   Sediment Pollution: Degradation of waters of the state by sediment as a result of failure to apply management or conservation practices to abate wind or water soil erosion, specifically in conjunction with earth-disturbing activities on land used or being developed for commercial, industrial, residential or other non-farm purposes.
