Restricted lead liquid

Liquid lead is 500 mg/L or more, so this restricted entry takes priority.

Restricted hazardous waste for liquids with lead at 500 mg/L or more. A result of exactly 500 mg/L is included.

Is California code 724 hazardous waste?

Not from the code alone. Code 724 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 724 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 724 cover?

This restricted entry is hazardous liquid with a representative lead result of 500 mg/L or more. The California code doesn't replace the separate test for federal lead toxicity or any other listing or characteristic.

Threshold: 500 mg/L or more in liquid
Official wording: 22 CCR division 4.5, chapter 11, Appendix XII(b)

Is lead liquid California code 724 or 132?

Code	When it fits
724	Representative lead is at least 500 mg/L in the liquid.
132	The aqueous liquid holds lead but stays below the restricted threshold.

The current Appendix XII threshold includes exactly 500 mg/L. DTSC's 2017 guidance says greater than 500 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.
