According to the refiled claim, the city seeks to hold Nicor and ComEd responsible for the waste oil contamination in and around the James Park neighborhood and for the methane, "both of which threaten public health and safety." Specifically, the suit asks that Nicor and ComEd abate the contamination "they caused or contributed to, by their acts and omissions" in addition to providing compensatory damages and "punitive damages for the willful and wanton conduct of Nicor and ComEd that has threatened, and continues to threaten, the safety of the city's residents."
