    Other neutralized metal waste

Ontario group: aqueous salts.

Other neutralized metal waste, aqueous salt solutions holding metals that are not heavy metals, after neutralization.

Is Ontario 132 hazardous waste?

Not from the code alone. Ontario 132 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 132 cover?

Neutralized residues containing other metals. Examples are sludge from treating aluminum before surface coating, alum sludge and gypsum sludge.

Is neutralized waste with other metals Ontario 132 or another class?

CodeWhen it fits
132The stream is neutralized residues containing other metals.
131The neutralized waste contains heavy metals rather than the other-metal group.

When several characterizations apply, the registration flowchart picks the primary one. A 3-digit class doesn't replace the flowchart or the exclusions.
