K087, Tar sludge from a coke-plant decanter tank.
K-listed waste
Tar sludge from a coke-plant decanter tank
Industry: Coking.
ComplyOnSiteIs K087 hazardous waste?
Yes. K087 is nonacute K-listed hazardous waste when the waste comes from the named process and matches the named stream. The federal table gives it hazard code (T), toxicity.
A K listing depends on where and how the waste was made, not on a test result alone. A test may add a characteristic code, but it doesn't remove the listing.
On a required hazardous waste manifest, put K087 in Item 13. Check the VSQG exemptions and empty-container rules too.
What does K087 cover?
Tar sludge from the decanter tank at a coking operation. The 261.4(a)(10) exclusion applies only if the sludge is recycled to coke ovens or tar recovery, or mixed with coal tar, and is not land disposed before recycling.

Is coke-plant decanter tar sludge always K087?
| Code | When it fits |
|---|---|
| K087 | Decanter tank tar sludge from coking operations. |
| K060 | Ammonia still lime sludge from coking operations. |
| K142 | Tar storage tank residues from producing coke from coal or from the recovery of coke by-products produced from coal. |
The industry, production step and waste form tell these K listings apart, not the chemicals in the waste. The rows above are only the nearby listed streams, so also add any characteristic or other listing that fits. One waste can carry more than one federal code.
