What is a WWTU?
Wastewater treatment units (WWTUs) are one of the ways generators can treat their own waste without a permit. They are also very common units. By definition, a WWTU must be a tank, must discharge under a Clean Water Act NPDES or pretreatment permit, and must manage RCRA hazardous wastewaters. [§260.10]
Remember, the WWTU exemption applies to the tank, not the hazardous waste within the tank. Also, in general, containers are portable when they contain waste and tanks are not. However, EPA has extended the WWTU exemption in guidance to cover mobile devices in appropriate cases. [52 FR 20919, RO 12220, 12928] Check with your state!
