K007, Wastewater sludge from making iron blue pigment.
K-listed waste
Wastewater sludge from making iron blue pigment
Industry: Inorganic pigments.
ComplyOnSiteIs K007 hazardous waste?
Yes. K007 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.
K007 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 K007 in Item 13. Look up the VSQG exemptions and empty-container rules too.
What does K007 cover?
Wastewater treatment sludge from making iron blue pigments. The waste form and its source process must both match the K-list wording.

Is iron blue pigment sludge K007, K006 or K005?
| Code | When it fits |
|---|---|
| K007 | Wastewater treatment sludge from producing iron blue pigments. |
| K006 | Wastewater treatment sludge from producing chrome oxide green pigments (anhydrous and hydrated). |
| K005 | Wastewater treatment sludge from producing chrome 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.
