Oxygenated solvent

Hazardous oxygenated solvent such as acetone, butanol or ethyl acetate.

Hazardous solvents such as acetone, butanol and ethyl acetate. Halogenated and hydrocarbon solvents have their own codes.

Is California code 212 hazardous waste?

Not from the code alone. The material must first be determined hazardous. California code 212 is not restricted, and a restricted code takes priority over it. A non-restricted code doesn't make a waste non-hazardous.

If the shipment needs the Uniform Hazardous Waste Manifest, enter 212 in Item 13 for the waste line. Use one California code, plus any federal RCRA codes when the waste is federally hazardous.

Waste is RCRA waste when it meets a federal listing or characteristic and no federal exclusion applies. Non-RCRA waste is hazardous under California rules only. California presumes hazardous waste is RCRA unless the generator shows it isn't, so keep that determination.

What does California code 212 cover?

This is for hazardous oxygenated solvents. Appendix XII names acetone, butanol and ethyl acetate as examples. Halogenated solvents and petroleum or hydrocarbon solvents have their own codes.

Rule: Appendix XII(b)
Official wording: 22 CCR division 4.5, chapter 11, Appendix XII(b)

Is an oxygenated solvent California code 212?

Code	When it fits
212	An oxygenated solvent such as acetone, butanol or ethyl acetate.
211	The solvent holds chlorine, fluorine, bromine or iodine, below any restricted threshold.
213	A petroleum-based or other hydrocarbon solvent.
214	The hazardous solvent mixture fits none of the specific solvent codes.

Identify the solvent's constituents and use history before choosing between the chemistry-based codes.

Which wastes take California code 212?

Waste	When it’s 212
Spent solvent	The solvent holds oxygen, as in acetone or butanol.
Spent acetone	Acetone was discarded or used as solvent.
Spent butanol	Butanol was discarded or used as solvent.
Spent ethyl acetate	Ethyl acetate was discarded or used as solvent.

Which codes sit beside California code 212?

221	Waste oil and mixed oil
222	Oil-water separator sludge
223	Other oily hazardous waste
231	Pesticide rinse water
232	Pesticide and pesticide-production waste
241	Tank-bottom waste
251	Still bottoms with halogenated organics
252	Other still-bottom waste
