ComplyOnSiteIs Alberta WSTCSO hazardous waste?
Not from the code alone. Alberta WSTCSO is the AER oilfield-waste code for corrosive solid waste. It fits only waste from the upstream facilities, wells or pipelines on that route. The code alone doesn't make the waste dangerous oilfield waste.
Dangerous oilfield waste stays on the AER route inside Alberta. It needs an Alberta hazardous-waste manifest only if it is exported from Alberta. Record the AER code in the oilfield waste information. A regulated export also needs the federal movement assessment, and a generic industrial category can't replace the AER code.
What does Alberta WSTCSO cover?
Corrosive solid waste. Use this fallback only if no other Directive 058 waste code fits. Directive 047 may audit its use. The code is tied to upstream oilfield origin. The actual composition and properties still decide whether the waste is dangerous and how to handle it.
When does corrosive solid waste Alberta WSTCSO fall under Alberta WSTCSO?
| Code | When it fits |
|---|---|
| WSTCSO | The upstream oilfield waste matches this description and no more specific Directive 058 code fits. |
Origin matters. Waste from an unrelated industrial activity doesn't become oilfield waste because its material has a similar name.
