D007, Chromium.
Characteristic hazardous waste
Chromium
Chromium at 5 mg/L or more in the TCLP extract.

Is D007 hazardous waste?
Yes. Waste is D007 when the TCLP extract of a representative sample holds chromium at or above 5 mg/L. That makes it toxic hazardous waste, whatever industry or process it came from.
Compare the chromium in the TCLP extract with 5 mg/L. A total chromium result is a different measure, so it can't be compared with this limit.
D007 is a nonacute characteristic. On a required hazardous waste manifest, put D007 in Item 13. See VSQG exemptions and empty-container rules.
What does D007 cover?
D007 applies when a representative sample gives a TCLP extract with chromium at or above 5 mg/L. The limit is for the extract, not the waste’s total chromium.

Is chromium waste always D007?
| Code | When it fits |
|---|---|
| D007 | The TCLP extract of a representative sample holds chromium at or above 5 mg/L. |
| D004–D043 | The chromium result is below 5 mg/L, but another contaminant or characteristic can still apply. |
Generators decide the codes from testing or knowledge of the waste, under 40 CFR 262.11. A result below 5 mg/L rules out D007 only. It doesn't make the waste nonhazardous.
Which wastes take D007?
| Waste | When it’s D007 |
|---|---|
| Waste contaminated with toxic metals | Its chromium leaches at the TCLP limit or above. |
| Chromium-contaminated waste | Its chromium leaches at the TCLP limit or above. |
| Contaminated soil | Its chromium leaches at the TCLP limit or above. |
| Paint and paint waste | Its chromium leaches at the TCLP limit or above. |
| Spray booth waste | Its chromium leaches at the TCLP limit or above. |
| Used paint filters | Its chromium leaches at the TCLP limit or above. |
| Adhesive and coating waste | Its chromium leaches at the TCLP limit or above. |
| Used oil | Its chromium leaches at the TCLP limit or above. |
Which codes sit beside D007?

| D004 | Arsenic |
| D005 | Barium |
| D006 | Cadmium |
| D008 | Lead |
