Characteristic hazardous waste
Chlordane

Chlordane at 0.03 mg/L or more in the TCLP extract.

Toxic characteristic waste. Waste with chlordane at 0.03 mg/L or more in the TCLP test. Chlordane is a banned termite pesticide.

Is D020 hazardous waste?

Yes. Waste is D020 when the TCLP extract of a representative sample holds chlordane at or above 0.03 mg/L. That makes it toxic hazardous waste, whatever industry or process it came from.

Compare the chlordane in the TCLP extract with 0.03 mg/L. A total chlordane result is a different measure, so it can't be compared with this limit.

D020 is a nonacute characteristic. On a required hazardous waste manifest, put D020 in Item 13. See VSQG exemptions and empty-container rules.

What does D020 cover?

D020 applies when a representative sample gives a TCLP extract with chlordane at or above 0.03 mg/L. The limit is for the extract, not the waste’s total chlordane.

CAS: 57-74-9
Regulatory level: 0.03 mg/L in TCLP extract
Hazard: T, toxic
Rule: 40 CFR 261.24

Is chlordane waste always D020?

Code	When it fits
D020	The TCLP extract of a representative sample holds chlordane at or above 0.03 mg/L.
D004–D043	The chlordane result is below 0.03 mg/L, but another contaminant or characteristic can still apply.
U036	Unused chlordane is thrown away pure, as technical grade, or as the product’s only active ingredient.

Generators decide the codes from testing or knowledge of the waste, under 40 CFR 262.11. A result below 0.03 mg/L rules out D020 only. It doesn't make the waste nonhazardous.

Which wastes take D020?

Waste	When it’s D020
Contaminated soil	Its chlordane leaches at the TCLP limit or above.
