interstate pollution control, inc.


The 2.8-acre Interstate Pollution Control (IPC) site is located northwest of Magnolia and Peoples Avenues in the south central part of Rockford, Winnebago County, Illinois. The site is located in an area that has been heavily industrialized since the early 1900s. Historic industrial activities in the area include metal casting, plating, machine tooling, textile manufacturing, leather tanning, and printing operations. The IPC property was originally a sand and gravel quarry. The city of Rockford used the quarry for waste disposal from 1942 until 1972, receiving residential, commercial, and industrial wastes, including large quantities of foundry sand. Aerial photographs and maps from the early to mid-1900s indicate there were several major quarries in the site vicinity. Most of these quarries have since been filled. A 1918 topographic map indicates a quarry existed beneath most of the IPC site. Later aerial photographs show the portions of the quarry under the site were completely filled in by 1943. Following filling of the quarry and immediately prior to IPC's operations, the site was an auto salvage yard. IPC operated as a hazardous waste storage facility serving 30 to 40 local industry facilities from 1974 to 1982. Typical wastes hauled and stored on site by IPC include: cyanide waste from electroplaters, paint sludges and residues, industrial solvents, and waste oils from industry and service stations. IPC had a long history of poor waste management practices. On-site features included: an unlined impoundment, leaking tanks, leaking drums, and a mixture of incompatible wastes. During IPC's operation, support services were provided to two sister companies: a portable toilet business and a Roto-Rooter franchise. The IPC site is surrounded by significant industrial facilities. The Gunite Foundry, located northeast of the site, has been in operation for at least 80 years. A former pet food plant, located immediately southwest of the site, processed meat and produced pet food from the turn of last century until the 1980s. The Peoples Avenue Landfill is located immediately southeast and south of the site. The U.S. Environmental Protection Agency (EPA) placed the IPC site on the National Priorities List (NPL) in 1989.
