K-listed waste
Wastewater sludge from making chrome oxide green pigment

Industry: Inorganic pigments.

Toxic K-listed waste from inorganic pigment plants. Sludge from treating wastewater at chromium oxide green plants, dry or hydrated.

Is K006 hazardous waste?

Yes. K006 is a nonacute K-listed hazardous waste when the named source process and waste stream match. The federal table gives it hazard code T for toxicity.

K006 is listed by source, so how and where the waste arose decides it, not a concentration test alone. A test can add a characteristic code but doesn't remove the listing once its conditions are met. On a required hazardous waste manifest, put K006 in Item 13. Look up the VSQG exemptions and empty-container rules too.

What does K006 cover?

Wastewater treatment sludge from making chrome oxide green pigments (anhydrous and hydrated). The waste form and its source process must both match the K-list wording.

Hazard code: T for toxicity
Industry: Inorganic pigments
Rule: 40 CFR 261.32

Is chrome oxide green pigment sludge K006, K005 or K008?

Code	When it fits
K006	Wastewater treatment sludge from producing chrome oxide green pigments (anhydrous and hydrated).
K005	Wastewater treatment sludge from producing chrome green pigments.
K008	Oven residue from producing chrome oxide green pigments.

The industry, production step and waste form pick the K listing, not the chemical content alone. The rows show nearby listed streams, not every code that could apply. Add any characteristic or other listing that also fits, since one waste can carry more than 1 federal code.
