ComplyOnSiteIs Ontario 122 hazardous waste?
Not from the code alone. Ontario 122 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 122 cover?
Cyanide-free alkaline residues with other metals or non-metals. Examples are cyanide-free alkaline liquids from coating or etching aluminum, discarded alkaline cleaners, lime sludge or slurry, and spent anion regenerant.
Is cyanide-free alkaline waste Ontario 122 or another class?
| Code | When it fits |
|---|---|
| 122 | The stream is cyanide-free alkaline residues with other metals or non-metals. |
| 123 | The waste is alkaline phosphate material rather than the other cyanide-free alkaline stream. |
When several characterizations apply, the registration flowchart picks the primary one. A 3-digit class doesn't replace the flowchart or the exclusions.
