Copper-production acid-plant blowdown sludge
Use K064 only when the waste stream and named Schedule 12 industry process both match.
ComplyOnSiteIs Federal K064 hazardous waste?
Yes, if the listing and federal definition apply. K064 is the federal listing for copper-production acid-plant blowdown sludge. The source, composition, concentration or test condition must match, and the exclusions in SOR/2021-25 still apply.
On a federally regulated international shipment, the applicant enters the waste classification in the waste-line details of the federal notification in CNMTS. Follow the movement rules and exclusions.
What does Federal K064 cover?
Acid plant blowdown slurry, and the sludge left when that slurry is thickened, from primary copper production. The waste form and its generating step must both match, so a similar material from another operation isn't K064.
- Official wording
- Acid plant blowdown slurry and sludge resulting from the thickening of blowdown slurry from primary copper production.

Is copper-production acid-plant blowdown sludge always Federal K064?
| Code | When it fits |
|---|---|
| K064 | It is copper-production acid-plant blowdown sludge from the named Schedule 12 process. |
Decide from where the material came from, how it was used, what is in it and the test results. A shared chemical or process word doesn't make 2 codes interchangeable. The full listed condition and any federal exclusion still decide.
