Frequent Questions

What are elementary neutralization units?

Elementary neutralization units are tanks, tank systems, containers, transport vehicles, or vessels used for neutralizing wastes that are hazardous only because they exhibit the corrosivity characteristic or because they are listed solely for the characteristic of corrosivity (Section 260.10). A tank, tank system, container, transport vehicle, or vessel that meets the definition of an elementary neutralization unit is exempt from permitting requirements under RCRA Subtitle C (Sections 264.1(g)(6), 265.1(c)(10), and 270.1(c)(2)(v)). In addition, generators managing hazardous waste immediately upon generation in an on-site elementary neutralization unit are not required to count those wastes toward their monthly generator status (Section 261.5(c)(2)).
