K-listed waste
Cleaning waste from making ink with chromium and lead

Industry: Ink formulation.

Toxic K-listed waste from ink makers. Washes & sludges from cleaning ink tubs & equipment where the ink holds chromium & lead.

Is K086 hazardous waste?

Yes. K086 is nonacute K-listed hazardous waste when the waste comes from the named process and matches the named stream. The federal table gives it hazard code (T), toxicity.

A K listing depends on where and how the waste was made, not on a test result alone. A test may add a characteristic code, but it doesn't remove the listing.

On a required hazardous waste manifest, put K086 in Item 13. Check the VSQG exemptions and empty-container rules too.

What does K086 cover?

Solvent, caustic or water washes and sludges from cleaning ink-formulation tubs or equipment. The ink must contain chromium- and lead-containing pigments, driers, soaps or stabilizers.

Is chromium-and-lead ink cleaning waste always K086?

Code	When it fits
K086	Solvent, caustic or water washes and sludges from cleaning ink-formulation tubs or equipment.

The industry, production step and waste form tell these K listings apart, not the chemicals in the waste. The rows above are only the nearby listed streams, so also add any characteristic or other listing that fits. One waste can carry more than one federal code.

What makes K086 source-specific?

K086 covers only the named waste form from the named ink formulation operation. Other wastes from that industry need their own listing check, and an unlisted waste must still be checked for hazardous characteristics.

Which codes sit beside K086?
