  • U-listed waste

    Cresol (cresylic acid)

U-list unused product.

U-listed hazardous waste for unused cresol, also called cresylic acid, a toxic phenol used in disinfectants & resins.

Is U052 hazardous waste?

Yes, when the listing applies. U052 covers cresol (cresylic acid) thrown away unused, including off-specification product and qualifying residues. It is a U-listed waste, not an acute P-listed one. The listing depends on the product and how it is discarded, not on a TCLP result alone.

U052 is nonacute hazardous waste. On a required hazardous waste manifest, put U052 in Item 13. VSQG exemptions and empty-container rules and pharmaceutical containers still apply.

What does U052 cover?

This covers cresol (cresylic acid) discarded unused, either pure or technical grade or as the only active ingredient in a formulation. It also covers off-specification batches, residues in nonempty containers and spill cleanup residues of those products. Inactive ingredients in the formulation don't affect this.

Is waste cresol (cresylic acid) always U052?

CodeWhen it fits
U052The unused chemical is thrown away, pure or technical grade or as the sole active ingredient. Residues from those products count too.
F004The solvent is spent after use, or is a still bottom from recovery. The F004 blend conditions also apply.
Characteristic waste (D001–D043)A used chemical or a different formulation shows a hazardous characteristic. Process listings can apply too.

A listed unused product can also have a characteristic, so more than one row can apply. Merely finding this chemical in a manufacturing waste doesn't make it U052. Match the waste's origin, formulation and use history. Mixing listed waste with solid waste, or treating it, generally doesn't remove the listing. That takes an exclusion, an exception or an approved delisting.
