K-listed waste
Leaded tank-bottom residue from a petroleum refinery

Industry: Petroleum refining.

Toxic K-listed waste from petroleum refineries. Leaded tank bottoms, the sludge left at the base of fuel storage tanks.

Is K052 hazardous waste?

Yes. K052 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 K052 in Item 13. Check the VSQG exemptions and empty-container rules too.

What does K052 cover?

Leaded tank bottoms from petroleum refining. The 261.4(a)(12)(i) recycling exclusion applies only if the residue goes back into refining with no land placement or speculative accumulation first. For thermal cracking, the coke must also be nonhazardous.

Is leaded tank-bottom residue from a refinery always K052?

Code	When it fits
K052	Tank bottoms (leaded) from the petroleum refining industry.
K051	API separator sludge from the petroleum refining industry.
K048	Dissolved air flotation (DAF) float from the petroleum refining industry.
K049	Slop oil emulsion solids from the petroleum refining industry.
K050	Heat exchanger bundle cleaning sludge from the petroleum refining industry.

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.

Which wastes take K052?

Waste	When it’s K052
Leaded gasoline tank bottoms	It is tank bottom from the petroleum refining industry containing leaded-gasoline constituents
