NPL Site Narrative for Rockwell International Corp. (Allegan Plant)

ROCKWELL INTERNATIONAL CORP. (ALLEGAN PLANT)
Allegan, Michigan

Federal Register Notice:  July 22, 1987

Conditions at proposal (April 10, 1985): Rockwell International Corp. manufactures universal joints for the automotive industry on a 30.4-acre site in Allegan, Allegan County, Michigan. The plant is in a residential neighborhood and on the banks of the Kalamazoo River, which is used for recreational activities.

During 1910-60, the company discharged waste water containing sludge, heavy metals, process wastes, and oils into the Kalamazoo River. During 1960-72, the waste water was discharged into two unlined ponds on the site. In 1972, the company built a plant to treat cutting fluid wastes, which contain emulsified oils, ferric chloride, sodium hydroxide, and a polymer flocculent. The treated wastes were discharged into one of two unlined ponds.

Ground water on the site is contaminated with lead, arsenic, cyanide, and 4-methyl-2-pentanone, according to tests conducted by EPA. Private wells downgradient of the plant are contaminated with heavy metals and cyanide, according to EPA. About 6,900 people depend on shallow wells within 3 miles of the site as a source of drinking water. EPA also detected heavy metals and polynuclear aromatic hydrocarbons in the Kalamazoo River.

In October 1980, Rockwell received Interim Status under Subtitle C of the Resource Conservation and Recovery Act by filing Part A of a permit application. Later, Rockwell withdrew the application because it did not meet Interim Status criteria.

Status (July 22, 1987): EPA is considering various alternatives for the site.
