  • K-listed waste

    Distillation residue from coal tar

Industry: Coking.

Listed withK-listed waste

Toxic K-listed waste from coking plants. Residues from coal tar distillation, including still bottoms, the heavy tar left in the still.

Is K148 hazardous waste?

Yes. K148 is a nonacute K-listed hazardous waste when the waste comes from the named process and stream. The federal table gives it hazard code (T), meaning toxicity.

Source decides a K listing, not a concentration test. A test can add a characteristic code, but it doesn't remove the K148 listing.

On a required hazardous waste manifest, put K148 in Item 13. See VSQG exemptions and empty-container rules.

What does K148 cover?

Residues from coal tar distillation, including still bottoms. The 261.4(a)(10) exclusion needs the residue recycled to coke ovens or tar recovery, or mixed with coal tar, with no land disposal before recycling.

Is coal tar distillation residue always K148?

CodeWhen it fits
K148Residues from coal tar distillation, including still bottoms.
K144Wastewater sump residues from light oil refining, including intercepting or contamination sump sludges from the recovery of coke by-products produced from coal.
K143Light-oil recovery residue from coke by-products, including still, decanter or wash-oil-unit residue.

The industry, production step and waste form tell these K listings apart, not the chemicals alone. The rows show nearby listed streams, not every code that could fit. Add any characteristic or other listing that also fits, because one waste can carry more than 1 federal code.
