  • Ontario leachate quality criteria

    2,4,5-T (2,4,5-Trichlorophenoxyacetic acid)

Ontario TCLP limit: 28 mg/L for 2,4,5-T (2,4,5-Trichlorophenoxyacetic acid).

Old phenoxy brush killer, mostly left in leftover farm and forestry stock. Ontario TCLP limit 28 mg/L.

Is Ontario E020 hazardous waste?

Yes, when the leachate limit is met. Ontario sets the leachate limit for 2,4,5-T at 28 mg/L in the TCLP extract. A result at 28 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 E020 cover?

This number is a limit on 2,4,5-T in the extract from the Toxicity Characteristic Leaching Procedure. The limit is 28 mg/L. It covers leachate toxicity, whatever the source industry, container or physical form. Ontario sets treatment requirements for land disposal separately.

Is 2,4,5-T always Ontario E020?

CodeWhen it fits
E020The TCLP extract holds 28 mg/L or more.
This constituent criterion not metThe TCLP extract is below 28 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.
