Characteristic hazardous waste
Benzene

Benzene at 0.5 mg/L or more in the TCLP extract.

Solvent drum with vapour, drawn for RCRA waste code D018, benzene. Fuel & solvent waste that leaches 0.5 mg/L or more. — Toxic characteristic waste. Waste with benzene at 0.5 mg/L or more in the TCLP test. Benzene is a fuel & solvent chemical.

Is D018 hazardous waste?

Yes. Waste is D018 when the TCLP extract of a representative sample holds benzene at or above 0.5 mg/L. That makes it toxic hazardous waste, whatever industry or process it came from.

Compare the benzene in the TCLP extract with 0.5 mg/L. A total benzene result is a different measure, so it can't be compared with this limit.

D018 is a nonacute characteristic. On a required hazardous waste manifest, put D018 in Item 13. See VSQG exemptions and empty-container rules.

What does D018 cover?

D018 applies when a representative sample gives a TCLP extract with benzene at or above 0.5 mg/L. The limit is for the extract, not the waste’s total benzene.

CAS: 71-43-2
Regulatory level: 0.5 mg/L in TCLP extract
Hazard: T, toxic
Rule: 40 CFR 261.24

Is benzene waste always D018?

Code	When it fits
D018	The TCLP extract of a representative sample holds benzene at or above 0.5 mg/L.
D004–D043	The benzene result is below 0.5 mg/L, but another contaminant or characteristic can still apply.
U019	Unused benzene 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 0.5 mg/L rules out D018 only. It doesn't make the waste nonhazardous.

Which wastes take D018?

Waste	When it’s D018
Contaminated soil	Its benzene leaches at the TCLP limit or above.
Asphalt waste	Its benzene leaches at the TCLP limit or above.
Used oil	Its benzene leaches at the TCLP limit or above.
Parts washer solvent	Its benzene leaches at the TCLP limit or above.
Solvent-contaminated wipes	Its benzene leaches at the TCLP limit or above.
