Use K144 only when the waste stream and named Schedule 12 industry process both match.
ComplyOnSiteIs Federal K144 hazardous waste?
Yes, if the listing and federal definition apply. Federal K144 is the listing for coal-coke light-oil refining sump residue. The source, composition, concentration or test condition on record must match, and the exclusions in SOR/2021-25 still apply.
On a federally regulated international shipment, the applicant records the waste classification in the waste-line details of the federal notification in CNMTS. The movement rules and exclusions apply.
What does Federal K144 cover?
Wastewater sump residue from refining light oil, including intercepting or contamination sump sludge, when recovering coke by-products from coal. Both the waste form and the step that made it must match, so a similar material from another operation isn't K144.

Is coal-coke light-oil refining sump residue always Federal K144?
| Code | When it fits |
|---|---|
| K144 | The waste is coal-coke light-oil refining sump residue from the named Schedule 12 process. |
Decide from where the material came from, how it was used, what it holds and the test results. A shared chemical or process word doesn't make codes interchangeable. The full listed condition and any federal exclusion still apply.
