  • U-listed waste

    Benz[a]anthracene

U-list unused product.

U-listed hazardous waste for unused benz[a]anthracene, a carcinogenic coal tar compound. It forms when coal & oil burn.

Is U018 hazardous waste?

Yes, when the listing applies. U018 covers the unused benz[a]anthracene described below when it is discarded, 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.

U018 is nonacute hazardous waste. On a required hazardous waste manifest, put U018 in Item 13. See VSQG exemptions and empty-container rules and pharmaceutical containers.

What does U018 cover?

This covers unused benz[a]anthracene discarded in pure or technical grade, or in a formulation where it is the only active ingredient. It also covers off-specification batches, residues in nonempty containers and spill cleanup residues from those products. Inactive ingredients don't stop benz[a]anthracene counting as the sole active ingredient.

Is benz[a]anthracene waste always U018?

CodeWhen it fits
U018The unused chemical is discarded as a pure or technical grade product or as the sole active ingredient. Residues from that product also count.
Characteristic waste (D001–D043)A used chemical or a different formulation meets a hazardous-waste characteristic. Check any process listings that apply too.

Both can apply, since a listed unused product can also show a characteristic. Having this chemical in a manufacturing waste doesn't make the waste U018. Match the waste's origin, formulation and use history. Mixing listed waste with solid waste, or treating it, doesn't normally remove the listing. Only an exclusion, an exception or an approved delisting does.
