ComplyOnSiteIs Ontario 150 hazardous waste?
Not from the code alone. Ontario 150 describes the waste stream, not whether it is hazardous. Ontario decides that from the hazardous characterization or liquid-industrial status, and from the exclusions. The 3-digit class needs a primary characterization letter to form the waste number.
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 also apply.
What does Ontario 150 cover?
Inert waste of inorganic composition. Examples are sand and water removed from a car-wash catch basin, and slurry from cutting or polishing marble.
Is inert inorganic waste Ontario 150 or another class?
| Code | When it fits |
|---|---|
| 150 | The stream is inert waste of inorganic composition. |
When several characterizations apply, the registration flowchart picks the primary one. A 3-digit class doesn't replace the flowchart or the exclusions.
