Frequent Questions

Is hazardous waste treatment permissible in an elementary neutralization unit?

An elementary neutralization unit is a device which:

(1) is used for neutralizing wastes that are hazardous only because they exhibit the corrosivity characteristic defined in §261.22, or they are listed in Part 261 Subpart D only for this reason; and 

(2) meets the definition of tank, tank system, container, transport vehicle, or vessel (§260.10). 

Treatment means any method, technique, or process, including neutralization, designed to change the physical, chemical, or biological character or composition of any hazardous waste so as to neutralize such waste, or so as to recover energy or material resources from the waste, or so as to render such waste non-hazardous, or less hazardous; safer to transport, store, or dispose of; or amenable for recovery, amenable for storage, or reduced in volume (40 CFR §260.10). Some forms of treatment are not regulated under RCRA, including treatment of hazardous wastes in an elementary neutralization unit.
