This is a Draft Environmental Impact Statement for a sewerage project involving a construction grant application that has been submitted by the North Shore Sanitary District (NSSD). When completed, the project will provide 48 million gallons per day (MGD) of sewage treatment capacity to serve the eastern portion of Lake County, Illinois. After weighing all the alternatives, this Statement reflects the view that the over-all project is sound, but that desirable modifications would include a smaller installation at Clavey Road (to offset the proximity of the plant to residential neighborhoods). The incorporation of some advanced waste treatment processes, a covered retention basin of reduced size, and a supplemental plant to be developed at a Des Plaines River location. Other adverse impacts will result from likely discharge of stormwater overflows to Lake Michigan in the northern portion of the project. It is recommended that these discharges be eliminated.
