Comparison: State vs. Federal

Rules. Arkansas adopts the federal rules at 40 CFR 260.10 for the chemical treatment of corrosive wastes, known as neutralization, to neutralize such waste and render it nonhazardous or less hazardous.

Arkansas follows the federal definition of ENU as a device that:

—Is used for neutralizing wastes that are hazardous wastes only because they exhibit the corrosivity characteristic or are listed as a hazardous waste only for this reason

—Meets the definition of tank, tank system, container, or transport vehicle or vessel

Administration and enforcement. ADEQ and EPA Region 6 administer and enforce the hazardous waste neutralization rules in Arkansas.
