K-listed waste
Float from dissolved-air flotation at a petroleum refinery

Industry: Petroleum refining.

Toxic K-listed waste from petroleum refineries. Float from dissolved air flotation units, oily froth skimmed off wastewater.

Is K048 hazardous waste?

Yes. K048 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 K048 in Item 13. Check the VSQG exemptions and empty-container rules too.

What does K048 cover?

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

Is refinery dissolved-air-flotation float always K048?

Code	When it fits
K048	Dissolved air flotation (DAF) float from the petroleum refining industry.
K051	API separator sludge from the petroleum refining industry.
K052	Tank bottoms (leaded) 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.
K169	Crude oil storage tank sediment from petroleum refining operations.
K170	Clarified slurry-oil tank sediment, in-line filter or separation solids, or both, from petroleum refining.

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 K048?

Waste	When it’s K048
Petroleum refinery dissolved-air-flotation float	It is dissolved-air-flotation float from petroleum refining wastewater treatment
