The Site has been utilized as a scrap yard by Zizzo Scrap Iron and Paper for over 30 years. Historically, the northern property has also been utilized as a coal yard and a junkyard. The southern property has also been utilized as a heating fuel supply company, motorcycle repair shop, and a city disposal company. Zizzo Scrap Iron operated an auto shredder where vehicles were loaded onto a conveyor ramp and loaded into the shredder. Non-metal portions of autos (fabric, cushioning, insulation, plastic, etc.) were ejected as "fluff' and steel was transported off-site and sold to steel manufacturers. Fluff was typically left on-site, either buried or left as waste piles along the perimeter of the property. The owner of the property is deceased and the property has been abandoned. Wisconsin Department of Natural Resources (WDNR) referred the Site to EPA due to the likely presence of contaminants such as heavy metals and PCBs.
