D009, Mercury.
Characteristic hazardous waste
Mercury
Mercury at 0.2 mg/L or more in the TCLP extract.

Is D009 hazardous waste?
Yes. Waste is D009 when the TCLP extract of a representative sample holds mercury at or above 0.2 mg/L. That makes it toxic hazardous waste, whatever industry or process it came from.
Compare the mercury in the TCLP extract with 0.2 mg/L. A total mercury result is a different measure, so it can't be compared with this limit.
D009 is a nonacute characteristic. On a required hazardous waste manifest, put D009 in Item 13. See VSQG exemptions and empty-container rules.
What does D009 cover?
D009 applies when a representative sample gives a TCLP extract with mercury at or above 0.2 mg/L. The limit is for the extract, not the waste’s total mercury.

Is mercury waste always D009?
| Code | When it fits |
|---|---|
| D009 | The TCLP extract of a representative sample holds mercury at or above 0.2 mg/L. |
| D004–D043 | The mercury result is below 0.2 mg/L, but another contaminant or characteristic can still apply. |
| U151 | Unused mercury 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 0.2 mg/L rules out D009 only. It doesn't make the waste nonhazardous.
Which wastes take D009?
| Waste | When it’s D009 |
|---|---|
| Waste contaminated with toxic metals | Its mercury leaches at the TCLP limit or above. |
| Mercury-contaminated waste | Its mercury leaches at the TCLP limit or above. |
| Contaminated soil | Its mercury leaches at the TCLP limit or above. |
| Demolition debris | Its mercury leaches at the TCLP limit or above. |
| Waste batteries | Its mercury leaches at the TCLP limit or above. |
| Fluorescent and mercury lamps | Its mercury leaches at the TCLP limit or above. |
| Mercury-containing equipment | Its mercury leaches at the TCLP limit or above. |
| Waste pharmaceuticals | Its mercury leaches at the TCLP limit or above. |
