  • Acute hazardousP-listed waste

    Dimetilan — a carbamate pesticide

P-list unused product.

Acute hazardous P-listed waste for unused dimetilan, a carbamate pesticide. It is in the strictest class.

Is P191 hazardous waste?

Yes, when the listing applies. P191 covers discarded, unused dimetilan, including off-specification product and qualifying residues. The P listing makes it acute hazardous waste, so the stricter acute quantities apply even for a small amount of the chemical.

Where a hazardous waste manifest is required, put P191 in Item 13. For exceptions, use the VSQG exemptions and empty-container rules and pharmaceutical containers.

What does P191 cover?

This listing covers unused dimetilan discarded as 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 from these products are included. Inactive ingredients don't stop the chemical counting as the sole active ingredient.

Is waste dimetilan always P191?

CodeWhen it fits
P191The unused chemical is discarded as pure or technical grade, or as the sole active ingredient. Qualifying product residues count too.
Characteristic waste (D001–D043)A used chemical or a different formulation shows a hazardous-waste characteristic. Any process listings that fit apply too.

A listed unused product can also show a characteristic, so more than one row can apply. Having this chemical somewhere in a manufacturing waste doesn't make the waste P191. Match the waste’s origin, formulation and use history. Mixing listed waste with solid waste, or treating it, generally doesn't remove the listing unless an exclusion, exception or approved delisting applies.
