Comparison: State vs. Federal

Rules. The federal rules and exemptions for neutralizing hazardous waste are effective in Illinois. As in federal regulation, Illinois allows for the chemical alteration of corrosive wastes known as elementary neutralization of wastes. This fairly common process is mentioned in the federal regulations at 40 CFR 260.10 and was incorporated by state regulation. For further guidance, see the national section NEUTRALIZATION OF WASTES.

The neutralization procedure involves adjusting the pH level of the corrosive waste so that it has a neutral value of 7. The waste may still be hazardous, however, if it has other characteristic properties, such as ignitability or toxicity. See the state sections CHARACTERISTIC WASTE and HAZARDOUS WASTE TREATMENT for more information.

Examples of industries that might use neutralization of wastes are automobile industries that use acids for cleaning engine parts that create an acidic corrosive waste and cleaning industries that use caustics in their operations that create an alkaline corrosive waste.

Administration and enforcement. IEPA's Bureau of Land administers and enforces the hazardous waste neutralization rules in Illinois.
