Waste Designation Decision Matrix - F or K Waste Determination
This matrix is provided as an assistance tool. It cannot be used as a substitute for following applicable city, state, and federal laws.
|Is the waste listed in the F or K lists in 40 CFR 261.31 and 40 CFR 261.32?|
Review the F and K lists. Make a note of the appropriate code for the waste you have for use later in the decision matrix.
You only look to these lists if the waste chemical was used in a process.
Some examples of F and K wastes include:
- Spent non-halogenated solvents, including (but not limited to) acetone, ethyl benzene, and methanol (F003).
- A drum of spent trichloroethylene (F002) solvent used for cleaning resins out of a product.
- Emission control dust/sludge from the primary production of steel in electric furnaces (K061).
- Tank bottoms (leaded) from the petroleum refining industry (K052)
