Sediment basins definition

Sediment basins means permanent basins that reduce the transport of waterborne pollutants such as eroded soil sediment, debris and manure sediment. Sediment basins may include con- tainment walls or berms, pickets or screens to filter debris, orifices or weirs to control discharge, and conduits to direct runoff to treat- ment or discharge areas.
