ComplyOnSiteWhere does Alberta D4 go on the Uniform Waste Code record?
In the management-code component. Alberta D4 describes what is done with the waste, not what the waste is or whether it is hazardous. It comes last in the Uniform Waste Code, after the waste category, transport product identification number and transport class. D operations are for disposal or treatment and R operations are for recovery or recycling.
The code must match what the receiving facility will actually do. Alberta’s guide shows how the codes are built but is not a current register of approved facilities. If the shipment needs an Alberta hazardous waste manifest, the consignor fills in the waste details and the receiver records receipt and handling in Part C. The code doesn't decide whether a manifest is needed.
What does Alberta D4 cover?
Containing waste at the surface, for example liquids or sludge held in a pit, pond or lagoon. This code describes the step, not a material or contaminant. It is one part of Alberta’s industrial identification system, and the same waste category takes a different management code when the actual treatment, disposal or recovery changes.
When do I use Alberta D4?

A management code doesn't approve the operation or show that a named facility can take the shipment. The hazardous-waste, recyclable and oilfield routes are separate questions.
