U117, Ethyl ether.

  • U-listed waste

    Ethyl ether

U-list unused product.

Ignitable U-listed hazardous waste for unused ethyl ether, a highly flammable solvent. Also called diethyl ether.

Is U117 hazardous waste?

Yes, when the listing applies. U117 is a nonacute U-listed hazardous waste, not an acute P-listed one. It covers unused ethyl ether thrown away, including off-specification product and qualifying residues. The listing depends on the product and how it is discarded, not on a TCLP result alone.

The listing rests only on ignitability, corrosivity or reactivity. Under 261.3(g) it stops applying once the waste shows no hazardous-waste characteristic. Another listing can still apply, and land disposal restrictions can continue.

Put U117 in Item 13 of a required hazardous waste manifest. The VSQG exemptions and empty-container rules and pharmaceutical containers still apply.

What is U117 waste?

It covers unused ethyl ether thrown away in pure or technical grade, or in a formulation where it is the only active ingredient. Off-specification batches, nonempty-container residues and spill cleanup residues count too. Inactive ingredients don’t change that.

Is ethyl ether waste always U117?

CodeWhen it fits
U117The unused chemical is thrown away pure, technical grade or as the sole active ingredient. Qualifying product residues fit too.
F003It is spent after solvent use, alone or blended before use only with F003 solvents. Recovery still bottoms fit too.
F001–F005Before use, the blend held an F003 solvent plus at least 10% by volume in total of F001, F002, F004 or F005 solvents.
Characteristic waste (D001–D043)A used chemical or a different formulation has a hazardous-waste characteristic. Any process listing that fits can apply too.

The rows can apply together, since a listed unused product can also have a characteristic. A manufacturing waste isn’t U117 just because it contains this chemical. Match the waste’s origin, formulation and use history. Mixing or treating listed waste doesn’t generally remove the listing. That takes an exclusion, an exception or an approved delisting that fits. Using the chemical as an ingredient or reactant doesn’t by itself make it a spent F-listed solvent. Compare each listing’s blend conditions before use.
