Ontario Schedule 3 severely toxic contaminant: 1,2,3,4,7,8-Hexachlorodibenzo-p-dioxin.
ComplyOnSiteIs Ontario S004 hazardous waste?
Yes, above the severely toxic concentration limit. In Ontario, waste with a Schedule 3 severely toxic contaminant above 1 ppm is severely toxic waste. S004 covers hexachlorodibenzo-p-dioxins (HxCDDs), CAS 39227-28-6. Exactly 1 ppm falls outside the test, but other hazardous definitions can still apply.
For shipments of this waste, the generator uses the class-and-letter waste number in the waste details of the Ontario hazardous waste manifest. The hazardous-waste number goes in the land-disposal assessment and notification where one is needed. Keep them together and don't swap one identifier for the other.
What does Ontario S004 cover?
S004 covers hexachlorodibenzo-p-dioxins (HxCDDs) under Ontario’s severely toxic waste rules, CAS 39227-28-6. The limit is above 1 ppm in the waste itself, not a concentration in TCLP leachate. The hazardous-waste number is also used in the land-disposal framework.

Is waste containing hexachlorodibenzo-p-dioxins (HxCDDs) Ontario S004?
| Code | When it fits |
|---|---|
| S004 | The waste holds the Schedule 3 severely toxic contaminant at more than 1 ppm. |
| Severely toxic concentration test not met | The contaminant is at or below 1 ppm. Other hazardous-waste definitions may still apply. |
Record the chemical and how it was measured with the result. This whole-waste limit is separate from the leachate-toxicity limits and from any land-disposal treatment requirement.
