    Bottom residue from making phthalic anhydride from naphthalene

Industry: Organic chemicals.

Listed withK-listed waste

Toxic K-listed waste from organic chemical plants. Distillation bottoms from making phthalic anhydride from naphthalene.

Is K024 hazardous waste?

Yes. K024 is nonacute hazardous waste when your waste comes from the named process and stream. The federal table gives it hazard code (T), for toxicity.

A K listing follows how and where the waste arose, not a concentration test. A test may add a characteristic code, but it doesn't remove this listing.

On a required hazardous waste manifest, put K024 in Item 13. Check the VSQG exemptions and empty-container rules too.

What does K024 cover?

This listing covers distillation bottoms from producing phthalic anhydride from naphthalene. The waste form and the source process must both match this listing. Chemical content alone isn't enough.

Are naphthalene-route phthalic bottoms always K024?

CodeWhen it fits
K024It is distillation bottoms from producing phthalic anhydride from naphthalene.
K023It is distillation light ends from producing phthalic anhydride from naphthalene.
K093It is distillation light ends from producing phthalic anhydride from ortho-xylene.

The industry, production step and waste form tell these K listings apart, not chemical content. The rows show nearby listed streams, not every code that could apply. Add any characteristic or other listing that also fits, because a waste can carry several federal codes.
