    Refinery flotation skimmings

Type 74 excludes the same residue from a source other than the petroleum refining industry.

Float from dissolved air flotation (DAF) units at petroleum refineries. Oily skimmings. Other industries are not included.

Is B.C. Type 74 hazardous waste?

Yes, when the Schedule 7 description and definition conditions are met. Type 74 is a Schedule 7 shipping name for a listed B.C. hazardous waste. The waste must match the entry's description and stay inside the hazardous-waste definition once exclusions are applied.

On a regulated listed-waste shipment, Type 74 is the shipping name on the B.C. hazardous waste manifest. B.C.’s exclusions and shipment rules still apply.

What does B.C. Type 74 cover?

Type 74 covers refinery flotation skimmings. It excludes the same residue from any source other than the petroleum refining industry. It is a B.C. shipping name for a listed waste, not a TDG class, and not a catch-all for similar material from another process.
