    By-product salts from making the herbicides MSMA and cacodylic acid

Industry: Pesticides.

Listed withK-listed waste

Toxic K-listed waste from pesticide plants. By-product salts from making the herbicides MSMA and cacodylic acid.

Is K031 hazardous waste?

Yes. K031 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 K031 in Item 13. Check the VSQG exemptions and empty-container rules too.

What does K031 cover?

This listing covers by-product salts from producing MSMA and cacodylic acid. The waste form and the source process must both match this listing. Chemical content alone isn't enough.

Are MSMA and cacodylic acid by-product salts always K031?

CodeWhen it fits
K031It is by-product salts from producing MSMA and cacodylic acid.
K124It is reactor vent scrubber water from producing ethylenebisdithiocarbamic acid and its salts.
K125It is filtration, evaporation, and centrifugation solids from producing ethylenebisdithiocarbamic acid and its salts.

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.
