ComplyOnSiteIs Ontario 253 hazardous waste?
Not from the code alone. Ontario 253 names the waste stream. Whether the waste is subject waste depends on its hazardous characterization or liquid-industrial status, and on the exclusions. The waste number also needs a primary characterization letter after the 3-digit class.
For subject waste, the generator enters the class-and-letter waste number in the waste details of the Ontario hazardous waste manifest. Ontario’s exclusions and shipment rules apply.
What does Ontario 253 cover?
Oil emulsions, such as soluble oil and discarded cutting or machine oil. Whether it is hazardous is a separate decision under Ontario’s waste rules.
Is oil emulsion waste Ontario 253 or another class?
| Code | When it fits |
|---|---|
| 253 | The stream is oil emulsion. |
| 252 | The discarded oil comes from crankcase or lubricating service, not from an emulsion. |
When several characterizations apply, the registration flowchart picks the primary one. The 3-digit class doesn’t replace the flowchart or the exclusions.
