W MARKLAND AVE

The Continental Steel Superfund site is located along West Markland Avenue in Kokomo, Indiana. It was operated by Continental Steel, and its predecessors, from approximately 1914 to 1986. Operations ceased at the site when Continental Steel filed for Chapter 11 bankruptcy. The facility produced nails, wire, and wire fence from scrap metal. Operations included steel reheating, casting, rolling, drawing, pickling, galvanizing, tinning, and tempering. The site is located in a mixed residential, commercial, and industrial use area and is mainly zoned for general use. The closest residents are located within 100 feet of the eastern fence line of the property, along South Leeds Street. The site is situated above three geologically significant aquifers. It encompasses approximately 183 acres and is divided into six operable units, consisting of an abandoned steel manufacturing facility (Main Plant), pickling liquor treatment lagoons (Lagoon Area), a former waste disposal area (Markland Avenue Quarry), a former waste disposal and slag processing area (Slag Processing Area), on-site creeks, and groundwater. The site was placed on the National Priorities List (NPL) in 1989. An interim Record of Decision (ROD) for the demolition and decontamination of the Main Plant buildings was signed in September 1996. A ROD, which outlined the final remedy for the entire site, was signed in September 1998. It was subsequently amended in 2003 to address new information gathered from predesign investigations performed by EPA in 2000-2001 and a five-year review performed by the Indiana Department of Environmental Management (IDEM) in 2002. On September 21, 2010, IDEM and EPA issued an Explanation of Significant Differences (ESD) for the Crushed Drum Area and the Acid Lagoon Area. Three five-year reviews have also been completed for the Site, with the last being conducted in 2012. The next five-year review of the site remedy is planned for August 2017.
