Storm water containment areas where sediment or suspended solids loads are above acceptable discharge limits

Storm water containment areas where nutrients, bacteria, metals, or hydrocarbon loads are above acceptable discharge limits

Areas where pretreatment of sediment and soluble pollutants is necessary to improve performance of downstream practices (i.e. treatment train design approach)

Areas where water quality is a concern; discharge is near receiving waters, fish bearing waters, high quality streams, recreational waters, sensitive aquatic ecosystems, or TMDL 303(d) designated waters.
