    Residues from making the herbicide 2,4,5-T

Industry: Pesticides.

Listed withK-listed waste

Toxic K-listed waste from pesticide plants. Heavy ends from distilling tetrachlorobenzene to make the herbicide 2,4,5-T.

Is K042 hazardous waste?

Yes. K042 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 K042 in Item 13. Check the VSQG exemptions and empty-container rules too.

What does K042 cover?

This listing covers heavy ends or distillation residues from distilling tetrachlorobenzene while producing 2,4,5-T. The waste form and the source process must both match this listing. Chemical content alone isn't enough.

Are residues from making the herbicide 2,4,5-T always K042?

CodeWhen it fits
K042It is heavy ends or distillation residues from distilling tetrachlorobenzene while producing 2,4,5-T.
K036It is still bottoms from toluene reclamation distillation while producing disulfoton.
K043It is 2,6-Dichlorophenol waste from producing 2,4-D.

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.
