ComplyOnSiteIs Manitoba EHS31 hazardous waste?
Yes, when the Schedule B threshold is met. EHS31 is a Category 3 Provincial Waste Code. It applies when ammonium thiosulphate reaches the Schedule B total mass-concentration threshold of 100 mg/kg.
The 3-digit provincial waste class goes in a separate field. It describes the waste stream and doesn't replace the UN Number or Provincial Waste Code.
For regulated hazardous waste, enter EHS31 in the UN Number or Provincial Waste Code field on the Manitoba movement document. Manitoba’s registration and shipment rules apply.
