Restoring Illinois water quality with TMDLs.

The establishment of a Total Maximum Daily Load sets the pollutant reduction goal necessary to improve impaired waters. It determines the load, or quantity of any given pollutant that can be allowed in a particular water body. A TDML must consider all potential sources of pollutants whether point or nonpoint. It also takes into account a margin of safety, which reflects scientific uncertainty, as well as the effects of seasonal variation.

The potentially responsible parties (PRPs) have removed the beaver dams and have collected the sediment samples they need for treatability studies. The treatability studies will establish the correct silt fence to minimize releases of sediment during the actual dredging to occur this fall. The studies will also determine the types and amounts of materials (lime, kiln dust, fly ash, etc.) required to stabilize the sediment, chemically tie up the metals and insure the sediment mixture will bear the weight of the cap on the Interim Storage Cell where the sediment will be placed. The Illinois Environmental Protection Agency (Illinois EPA) anticipates work to be completed by late fall or early winter 2004, if lake and river levels that affect the South Ditch are at their normal seasonal levels.
