U-listed waste
Ethylene dichloride

U-list unused product.

Toxic U-listed hazardous waste for unused ethylene dichloride, a chlorinated solvent & PVC feedstock.

Is U077 hazardous waste?

Yes, when the listing applies. U077 covers unused ethylene dichloride that is thrown away, including off-specification product and qualifying residues. It is a U-listed waste, not an acute P-listed one. Whether it is listed depends on the product and how it is discarded, not on a TCLP result alone.

U077 is nonacute hazardous waste once the listing holds. On a required hazardous waste manifest, put U077 in Item 13. Also read VSQG exemptions and empty-container rules and pharmaceutical containers.

What does U077 cover?

Unused ethylene dichloride counts when it is discarded pure, in technical grade, or as the only active ingredient of a formulation. Off-specification batches, residues left in non-empty containers and spill cleanup residues of those products count too. Inactive ingredients don't stop it being the sole active ingredient.

Is waste ethylene dichloride always U077?

Code	When it fits
U077	The unused chemical is thrown away pure, in technical grade or as the sole active ingredient. Qualifying product residues count too.
D028	The TCLP extract holds 1,2-Dichloroethane at 0.5 mg/L or more. The product listing can apply too.
Characteristic waste (D001–D043)	A used chemical or a different formulation shows a hazardous-waste characteristic. Assess any process listings too.

The rows can stack, since an unused listed product can also show a characteristic. Finding the chemical in manufacturing waste doesn't make that waste U077. Go by where the waste came from, what was in it and how it was used. Mixing listed waste with other solid waste, or treating it, usually doesn't end the listing. That takes an exclusion, an exception or an approved delisting.

Which wastes count as U077?
