E104, Boron.
Ontario leachate quality criteria
Boron
Ontario TCLP limit: 500 mg/L for Boron.
ComplyOnSiteIs Ontario E104 hazardous waste?
Yes, when the leachate limit is met. Ontario sets the leachate limit for boron at 500 mg/L in the TCLP extract. A result at 500 mg/L meets it, subject to the regulation’s exclusions. A concentration in the original bulk waste is a different measurement, so it can't be compared with this limit.
For a shipment of this waste, the generator enters the 3-digit class and primary characterization in the waste-number details of the Ontario hazardous waste manifest. This number names the constituent for the assessment but doesn't replace the class-and-letter waste number. Land-disposal treatment standards are assessed separately.
What does Ontario E104 cover?
This number is a limit on boron in the extract from the Toxicity Characteristic Leaching Procedure. The limit is 500 mg/L. It covers leachate toxicity, whatever the source industry, container or physical form. Ontario sets treatment requirements for land disposal separately.

Is boron always Ontario E104?
| Code | When it fits |
|---|---|
| E104 | The TCLP extract holds 500 mg/L or more. |
| This constituent criterion not met | The TCLP extract is below 500 mg/L. |
A result below the limit clears this constituent only. Other constituents, characteristic hazards and listed-waste rules still need assessing. Test against the classification limit first, then the land-disposal treatment standard.
Which wastes take Ontario E104?
| Waste | When it’s E104 |

| Contaminated soil | When the measured extract concentration meets the individual limit. |
