E110, Diclofop-methyl.

  • Ontario leachate quality criteria

    Diclofop-methyl

Ontario TCLP limit: 0.9 mg/L for Diclofop-methyl.

Diclofop-methyl waste. Grass herbicide sprayed on wheat, barley & canola. Mostly left in farm stock. Ontario TCLP limit 0.9 mg/L.

Is Ontario E110 hazardous waste?

Yes, when the leachate limit is met. Ontario sets the leachate limit for diclofop-methyl at 0.9 mg/L in the TCLP extract. A result at 0.9 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 E110 cover?

This number is a limit on diclofop-methyl in the extract from the Toxicity Characteristic Leaching Procedure. The limit is 0.9 mg/L. It covers leachate toxicity, whatever the source industry, container or physical form. Ontario sets treatment requirements for land disposal separately.

Is diclofop-methyl always Ontario E110?

CodeWhen it fits
E110The TCLP extract holds 0.9 mg/L or more.
This constituent criterion not metThe TCLP extract is below 0.9 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.
