    Endrin — an insecticide

P-list unused product.

Acute hazardous P-listed waste for unused endrin & its metabolites, a toxic organochlorine insecticide.

Is P051 hazardous waste?

Yes, when the listing applies. P051 covers unused endrin that is thrown away, including off-specification product and qualifying residues. It is a P-listed waste, so it is acute hazardous waste and the stricter acute quantities apply even for small amounts.

On a required hazardous waste manifest, put P051 in Item 13. For VSQG exemptions and empty-container rules and pharmaceutical containers, follow the linked rules.

What does P051 cover?

Unused endrin is included when thrown away as pure or technical grade, or as the only active ingredient in a formulation. That includes off-specification batches, residues in non-empty containers and spill cleanup residues. Inactive ingredients don't change this.

CAS qualification
The table gives the CAS of the parent compound. It doesn't cover every salt or derivative.

Is waste endrin always P051?

CodeWhen it fits
P051The unused chemical is thrown away pure, as technical grade or as the only active ingredient. Residues from that product fit too.
D012The waste's TCLP extract holds endrin at 0.02 mg/L or more. The product listing can apply too.
Characteristic waste (D001–D043)A used chemical or a different formulation meets a hazardous-waste characteristic. Check any process listings too.

A listed unused product can also show a characteristic, so both rows can fit together. A manufacturing waste that merely contains this chemical is not P051. Match the waste's origin, formulation and use history. Mixing listed waste with solid waste, or treating it, usually doesn't remove the listing. Only an exclusion, exception or approved delisting does. The CAS number is for the parent compound and doesn't prove every salt shares it, so the listed chemical wording decides.
