I am putting together a SWPPP for a site that will have disturbed portions within 20' of a Surface Water. I have estimated the % removal efficiency as if I had retained a 50' natural buffer - 26%. Now I need to design BMPs capable of achieving equivalent sediment removal efficiency. I downloaded RUSLE and managed to input my site conditions and also modeled a silt fence. I have attached a copy of the results from RUSLE. My problem is I don't know how to interpret them. The results give numbers with units of tons per acre per year. I need to know the Percent Removal Efficiency suggested by the results. Can anyone help me determine the Percent Removal Efficiency suggested by the RUSLE results? Thank you!
Since the later 1980s, manufacturing companies have seen over 3 percent in labor output year on year, with most of this productivty enhancement occuring because of the optimization of repetitive tasks. Download Now
