Low-organic water-based liquid

Total organic residue is below 10%.

Water-based liquid with total organic residue below 10%. At exactly 10% or more it takes code 133 instead.

Is California code 134 hazardous waste?

Not from the code alone. The material must first be determined hazardous. California code 134 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 134 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 134 cover?

This is for hazardous aqueous solution whose total organic residue is below 10%. It is the low-organic pair of code 133.

Threshold: Below 10% total organic residue
Rule: Appendix XII(b)
Official wording: 22 CCR division 4.5, chapter 11, Appendix XII(b)

Is a low-organic water-based liquid California code 134?

Code	When it fits
134	Measured total organic residue is below 10%.
133	Measured total organic residue is 10% or more.

The 2017 DTSC list draws the same line at below 10%. Exactly 10% is code 133.

Which wastes take California code 134?

Waste	When it’s 134
Waste antifreeze	A hazardous water-based solution with less than 10% total organic residue.
