GREEN BAY, WI (WTAQ) - A federal judge in Green Bay denied a paper company’s request to delay his earlier order to resume dredging along the Fox River as part of a clean-up effort of toxic chemicals.  NCR Corporation was ordered last week to immediately restart clean-up efforts after it halted the project last year and filed a lawsuit.  The judge laid out a strict schedule for clean-up through November, and said on Friday that dredging should continue by May 17^th.  NCR Corporation is one of numerous paper companies that are responsible for the clean-up after dumping PCBs in the river for decades as a result from making carbonless paper.
