    Nitrate + Nitrite

Use L22 when its Method 1311 extract result is >= 1000.000 mg/L.

Leachate toxic waste, where the Method 1311 extract holds 1000 mg/L or more of nitrate + Nitrite.

Is Federal L22 hazardous waste?

Yes, if the listing and federal definition apply. L22 lists nitrate + Nitrite. The source, composition, concentration or test condition on record must match, and the exclusions in SOR/2021-25 still apply.

On a federally regulated international shipment, the applicant records the waste classification in the waste-line details of the federal notification in CNMTS. The movement rules and exclusions still apply.

What does Federal L22 cover?

L22 covers nitrate + Nitrite. Use it when the Method 1311 extract result is 1000.000 mg/L or more. The material, source and any stated composition, concentration, test or use condition must also match. The name alone isn't enough.
