Oil-and-water mixtures
National reporting J120: use for an emulsion or mixture of water with oil or another hydrocarbon.
Is National J120 hazardous waste?
Not from the code alone. J120 is a DCCEEW reporting category that groups waste data nationally. It doesn't make every material with this description hazardous. State and territory rules decide the classification, exclusions and movement duties for a real load.
Enter J120 in the national waste-data category field when reporting under that standard. It isn't a transport certificate. A movement needs the code and record accepted where it starts, plus any required destination consignment authorisation for an interstate controlled load. Apply separate interstate movement controls, because a reporting code gives no state movement classification.
What does National J120 cover?
Water mixed or emulsified with oil or another hydrocarbon goes here. National examples are vehicle and industrial washwater, antifreeze, boiler or cooling-system water, and mixtures on either side of 50% oil or hydrocarbon.
