Leachate toxic waste with 320 mg/L or more of nitrite in the extract. Nitrite is a preservative & corrosion-inhibitor salt.

Is Federal L24 hazardous waste?

Yes, if the listing and federal definition apply. L24 is the federal listing for nitrite. The recorded source, composition, concentration or test condition must match, and the exclusions in SOR/2021-25 still hold.

For federally regulated international shipments, the applicant records the waste classification in the waste-line details of the federal notification in CNMTS. The movement rules and exclusions go with it.

What waste does Federal L24 cover?

L24 covers nitrite. Use it when the Method 1311 extract result is 320.00 mg/L or more. Match the material, source and any stated composition, concentration, test or use condition. The name alone isn't enough.
