    Organic waste from making carbamates or carbamoyl oximes

Industry: Organic chemicals.

Listed withK-listed waste

Toxic K-listed waste from organic chemical plants. Heavy ends, still bottoms, spent solvents & filtrates from carbamate production.

Is K156 hazardous waste?

Yes. K156 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 K156 listing.

On a required hazardous waste manifest, put K156 in Item 13. See VSQG exemptions and empty-container rules.

What does K156 cover?

Organic waste from making carbamates and carbamoyl oximes, including heavy ends, still bottoms, light ends, spent solvents, filtrates and decantates. Waste from making 3-iodo-2-propynyl n-butylcarbamate is not included.

Is carbamate production organic waste always K156?

CodeWhen it fits
K156Organic waste (including heavy ends, still bottoms, light ends, spent solvents, filtrates, and decantates) from producing carbamates and carbamoyl oximes.
K157Wastewaters (including scrubber waters, condenser waters, washwaters, and separation waters) from producing carbamates and carbamoyl oximes.
K158Bag house dusts and filter/separation solids from producing carbamates and carbamoyl oximes.

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.
