Listed withK-listed waste

Toxic K-listed waste from inorganic pigment plants. Wastewater treatment sludge from making zinc yellow pigments.

Is K004 hazardous waste?

Yes. K004 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.

K004 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 K004 in Item 13. Look up the VSQG exemptions and empty-container rules too.

What does K004 cover?

Wastewater treatment sludge from making zinc yellow pigments. The waste form and its source process must both match the K-list wording.

Is zinc yellow pigment sludge K004, K002 or K003?

CodeWhen it fits
K004Wastewater treatment sludge from producing zinc yellow pigments.
K002Wastewater treatment sludge from producing chrome yellow and orange pigments.
K003Wastewater treatment sludge from producing molybdate orange 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.
