Restricted selenium liquid

Liquid selenium is 100 mg/L or more, so this restricted entry takes priority.

Restricted hazardous waste for liquids with selenium at 100 mg/L or more. A result of exactly 100 mg/L is included.

Is California code 727 hazardous waste?

Not from the code alone. Code 727 is a restricted waste code, so it wins over any non-restricted code that also fits. Choose it after the hazardous waste determination. It doesn't prove the waste is hazardous or decide its federal RCRA status.

If a shipment needs the Uniform Hazardous Waste Manifest, enter 727 in Item 13 for its waste line. Use one California code, plus the federal RCRA codes when the waste is federally hazardous.

RCRA waste meets a federal listing or characteristic and has no federal exclusion. 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 record.

What does California code 727 cover?

This restricted entry is hazardous liquid with a representative selenium result of 100 mg/L or more. A lower result falls outside this entry, but the waste can stay hazardous under another listing or characteristic.

Threshold: 100 mg/L or more in liquid
Official wording: 22 CCR division 4.5, chapter 11, Appendix XII(b)

Is selenium liquid California code 727 or 132?

Code	When it fits
727	Representative selenium is at least 100 mg/L in the liquid.
132	The aqueous liquid holds selenium but stays below the restricted threshold.

The current Appendix XII threshold includes exactly 100 mg/L. DTSC's 2017 guidance says greater than 100 mg/L. If more than one restricted code fits, confirm the single California code for the waste line. The rules give no general tie-breaker.
