    Coal-coke light-oil recovery process residue

Use K143 only when the waste stream and named Schedule 12 industry process both match.

Federal K code for process residues from light oil recovery in stills, decanters and wash oil units at coke by-product plants.

Is Federal K143 hazardous waste?

Yes, if the listing and federal definition apply. Federal K143 is the listing for coal-coke light-oil recovery process 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 K143 cover?

Residue from recovering light oil, including residue from stills, decanters and wash oil recovery units, 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 K143.

Official wording
Process residues from the recovery of light oil, including those generated in stills, decanters and wash oil recovery units from the recovery of coke by- products produced from coal.

Is coal-coke light-oil recovery process residue always Federal K143?

CodeWhen it fits
K143The waste is coal-coke light-oil recovery process 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.
