D024, m-Cresol.

  • Ontario leachate quality criteria

    m-Cresol

Ontario TCLP limit: 200 mg/L for m-Cresol.

M-Cresol waste. Phenolic disinfectant & solvent from coal tar, in the meta form. Ontario TCLP limit 200 mg/L.

Is Ontario D024 hazardous waste?

Yes, when the leachate limit is met. Ontario sets the leachate limit for m-Cresol at 200 mg/L in the TCLP extract. A result exactly at the limit meets it, subject to the regulation’s exclusions. The concentration in the original bulk waste is a different measure.

For a subject-waste shipment, the generator records 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 and doesn’t replace that class-and-letter waste number. Land-disposal treatment standards are assessed separately.

What is Ontario D024?

This number covers m-Cresol in the extract from the Toxicity Characteristic Leaching Procedure. Its classification limit is 200 mg/L. It marks a toxic leachate, whatever the industry, container or physical form. Ontario sets treatment requirements for land disposal separately.

Is m-Cresol waste Ontario D024?

CodeWhen it fits
D024The TCLP extract reaches or exceeds the limit of 200 mg/L.
This constituent criterion not metThe TCLP extract is below 200 mg/L. Other hazardous criteria still need assessment.

A result below the limit for one constituent doesn’t settle other constituents, characteristic hazards or listed-waste rules. Apply the classification threshold first, then the land-disposal treatment standard.
