The Continental Steel Corporation site is located on West Markland Avenue in Kokomo, Indiana. The site encompasses about 183 acres and consists of an abandoned steel manufacturing facility (Main Plant), pickling liquor treatment lagoons (Lagoon Area), a former waste disposal area (Markland Avenue Quarry), and a former waste disposal and slag processing area (Slag Processing Area). The Main Plant is the portion of the facility south of West Markland Avenue and east of Wildcat Creek. The Main Plant includes 25 buildings, many of which are severely deteriorated.The Continental Steel Corporation was founded as the Kokomo Fence Machine Company in 1896. In 1899, the Kokomo Fence Machine Company was consolidated with other interests to form the Kokomo Nail & Wire Company. In 1900, the company was reorganized under the name of Kokomo Steel and Wire Company. Two 75 ton open-hearth furnaces were erected in 1914, and this furnace was put into service in 1917. In 1927, the Kokomo Steel & Wire Company merged with two other steel companies to form the Continental Steel Corporation. By 1947, the other two steel companies were divested, and the Continental Steel Corporation manufacturing facilities were centered in Kokomo. The site was acquired in 1969 and changed names. The company declared bankruptcy in 1980 and came out of bankruptcy in 1982 again as the Continental Steel Corporation, only to again file for bankruptcy in 1985. The facility soon closed in February 1986.Throughout its history, the plant produced nails, wire, and wire fence from scrap metal. Operations included reheating, casting, rolling, drawing, pickling, annealing, hot-dip galvanizing, tinning, and oil tempering. The steel manufacturing operations at the plant included the use, handling, treatment, storage, and disposal of hazardous materials.Waste pickle liquor, used to remove by-products such as scale and rust from cooling steel, was stored in the Lagoon Area. Investigations of the on-site groundwater identified chromium, cadmium, lead, and iron contamination. Water in the quarry contained traces of organic solvents, and low levels of copper, zinc, and mercury. The Main Plant area was contaminated with polychlorinated biphenyls (PCBs), baghouse dust (a listed waste containing chromium and lead), and sludge contaminated with trichloroethylene.The area surrounding the facility is a mixed residential, commercial, and industrial area and is zoned for general use, except for the Main Plant, which has an industrial use only deed covenant. Residential properties are located to the east of the Main Plant. A mix of residential and industrial properties exist to the north and west, and industrial properties are located to the south. The closest residents to the plant are located within 100 feet east of the site, near the property fence line along South Leeds Street, and south of the Main Plant across Kokomo Creek. Highland Park, a public recreation area for area residents, lies to the south of the Main Plant just across Kokomo Creek.The Main Plant consists of about 94 acres and includes abandoned buildings. Many buildings have basements, some of which are flooded with groundwater. A network of underground sewers and utility lines are also located on site. Some processing equipment has been removed from the facility.
Remedy:  This remedial action is an interim remedy for the Continental Steel Corp. site. This interim remedy addresses the contamination detected inside the deteriorated Main Plant buildings and in the Manin Plant building basements. As this is an interim remedy, the remaining surface and sub-surface contamination will be addressed in a future final remedy.The major components of the selected interim remedy include: gross removal of lead dust from contaminated building interiors using vacuuming and/or pressure washing with disposal of dust as hazardous waste in a permitted facility; management and proper disposal of rinsate collected from decontamination with the rinsate water being managed as hazardous waste until receipt of waste characterization analysis; asbestos abatement by removal and disposal at a permitted facility of exposed friable asbestos-containing materials and asbestos containing building insulation; confirmation sampling to ensure proper decontamination; removal of PCB-contaminated wood block floors and disposal as hazardous waste; demolition of all building superstructures, tanks, and equipment to grade, leaving floor slabs; salvaging of structural steel as scrap unless it can be decontaminated and reused as originally intended; disposal of all debris and demolition rubble as hazardous, special or non-hazardous waste as determined by waste characterization; use of water spray for dust control during demolition with the dust control water runoff being contained and managed properly to prevent the transport of contaminants from the immediate demolition site; pumping out of flooded basements, removal of equipment and residue from basements and filling of basements with the pumped water being managed as hazardous waste until receipt of waste characterization analyses; filling or covering of pits; confirmational sampling to verify effectiveness of decontamination; finishing of unpaved areas with crushed stone; and securing of the site after the interim remedy is completed.
