Acute hazardousP-listed waste
Phorate — an insecticide and nematicide

P-list unused product.

Acute hazardous P-listed waste for unused phorate, a highly toxic organophosphate insecticide & nematicide. Unused product only.

Is P094 hazardous waste?

Yes, when the listing applies. P094 is for unused phorate that is thrown away, including off-specification product and qualifying residues. It is acute hazardous waste, so the stricter acute quantities apply even for a small amount.

Put P094 in Item 13 of a required hazardous waste manifest. The VSQG exemptions and empty-container rules and pharmaceutical containers have their own limits.

What does P094 cover?

It covers unused phorate thrown away pure, at technical grade, or in a formulation where it is the only active ingredient. It also takes in off-specification batches, residues left in nonempty containers and cleanup residues from spills of these products. Inactive ingredients don't stop it counting as the only active ingredient.

Is phorate waste P094 or another code?

Code	When it fits
P094	Thrown away unused, pure or technical grade, or as the only active ingredient. Qualifying product residues count too.
Characteristic waste (D001–D043)	A used chemical or a different formulation that meets a hazardous-waste characteristic. Any process listings that apply count too.

Both rows can apply at once, because a listed unused product can also have a characteristic. Having this chemical in a manufacturing waste doesn't make the waste P094. Match the waste's origin, formulation and use history. Mixing or treating listed waste generally doesn't remove the listing. That takes an exclusion, an exception or an approved delisting.

Which wastes take P094?

Waste	When it’s P094
Waste pesticides	Unused phorate thrown away as a commercial product, with phorate the only active ingredient.
