    Dinitrotoluenes (excluding 2,4-dinitrotoluene)

Manitoba total-mass limit: 100 mg/kg for Dinitrotoluenes (excluding 2,4-dinitrotoluene).

Manitoba hazardous waste containing dinitrotoluenes except 2,4-DNT at 100 mg/kg or more by total mass.

Is Manitoba EHS81 hazardous waste?

Yes, when the Schedule B threshold is met. EHS81 is a Category 3 Provincial Waste Code. It applies when dinitrotoluenes except 2,4-DNT reaches the Schedule B total concentration of 100 mg/kg by mass.

The 3-digit provincial waste class goes in a separate field. It doesn't replace the UN Number or Provincial Waste Code.

For regulated hazardous waste, enter EHS81 in the UN Number or Provincial Waste Code field on the Manitoba movement document. Manitoba’s registration and shipment rules still apply.

What does Manitoba EHS81 cover?

EHS81 tests waste for dinitrotoluenes except 2,4-DNT. Measure the total concentration by mass. At 100 mg/kg or more, the waste is hazardous-waste Category 3 with code EHS81.
