5900 INDUSTRIAL HIGHWAY

The Midco II site is located in the city of Gary, Lake County, Indiana. It is located in a predominantly industrial area where 34 other potential hazardous waste sites have been identified. The site occupies approximately 7 acres of sandy soil and fill, contaminated groundwater, and ditch sediments located at 5900 Industrial Highway. The original ridge and swale topography was filled in with industrial wastes to create a relatively flat surface during the 1950s and 1960s. The site is 1.14 miles south of Lake Michigan and 0.85 miles north of the Grand Calumet River. Midco II was used for temporary bulk liquid and drum storage of waste materials, neutralization of acids and caustics, and dumping of wastes. These operations began in 1976 following a fire at the Midco I facility. In 1977, an additional fire at Midco II destroyed equipment, buildings, and an estimated 50,000 to 60,000 drums containing chemical wastes. This resulted in additional spillage across the site and contamination of the soil and groundwater. Site Responsibility The site is being addressed through a combination of federal and state actions and federal and state oversight of potentially responsible party (PRP) actions.
