This report provides detailed descriptions of: The logic used for dredge area delineation; The data analyses used to characterize the river sediments and the associated PCBs; The rationale used for targeting specific sediment areas; and The methodology for establishing the horizontal and vertical boundaries of those the areas meeting the criteria for removal, volume of contaminated sediments, and PCB inventory within those areas.
