How to neutralize your hazardous waste without a permit

Let’s say you have a waste that is hazardous solely because it exhibits the corrosivity characteristic (a D002 characteristic waste), you can neutralize it chemically in a tank or container prior to discharging it through a permit under the Clean Water Act. This is known as the Elementary Neutralization Unit Exemption.

This exemption will not apply if your waste also exhibits other hazardous characteristics (such as ignitability, toxicity or reactivity) or if it is a listed hazardous waste. Under this exemption, the unit (tank or container) where the neutralization occurs is exempt from RCRA standards. However, any sludge that comes out of this process is not exempt. If the sludge exhibits any hazardous characteristic, it will need to be managed as hazardous waste under RCRA.

Another point top remember is that if you have a separate container that is holding your D002 waste waiting to be neutralized, that container is NOT a treatment unit.neutra

Under this Federal exemption, you will not need to obtain a CRA Part B permit in order to treat your hazardous waste. Note that not all states have adopted this exemption. So always check with your state agencies.
