Rules. The federal rules and exemptions for neutralizing hazardous waste are effective in Iowa. The federal regulation for the chemical alteration of corrosive wastes, known as elementary neutralization of wastes, is a fairly common process mentioned in the federal regulations at 40 CFR 260.10. 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 national 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. EPA's Region 7 office enforces the federal Resource Conservation and Recovery Act (RCRA) hazardous waste neutralization requirements in Iowa because the state does not have EPA authorization to implement its own hazardous waste management program. See the state section HAZARDOUS WASTE (REGULATORY OVERVIEW) for more information.
