• Rules. Mississippi adopts by reference the federal rules and exemptions for the chemical alteration of corrosive wastes known as the elementary neutralization of hazardous wastes, including the definition of elementary neutralization units, and the standards for the treatment of ignitable or reactive 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 section HAZWASTE DETERMINATION (CLASSIFICATION) for more information on characteristic and listed hazardous wastes.
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. For further guidance, see the national section NEUTRALIZATION OF WASTES.
