CHICAGO (AP) -- Illinois authorities have filed a lawsuit against Caterpillar Inc. after oil that overflowed from company waste treatment tanks spilled into a suburban Chicago river.
Attorney General Lisa Madigan and Will County State's Attorney James Glasgow filed the seven-count complaint Monday in Will County alleging several violations, including endangering the environment.
The complaint seeks thousands of dollars in penalties from the Peoria-based maker of construction and mining equipment.
Around 65,000 gallons of oil overflowed from the Joliet facility. About 6,500 gallons flowed into the Des Plaines River.
Glasgow says Caterpillar acted fast to report the Feb. 8 incident and there was no major environmental damage. But he wants Caterpillar to ensure such spills can't happen again.
