Federal Toxicity Characteristics
A waste is considered toxic per Federal toxicity characteristics when:
- it is analyzed by the Toxic Characteristic Leaching Procedure (TCLP) method
- contains a chemicals listed below in concentrations that equal or exceed the regulatory threshold (RT)

1 If o-, m- and p- Cresol concentrations cannot be differentiated the total cresol (D026) concentration is used. The regulatory level of total cresol is 200 mg/l.
2 Quantitation limit is greater than the calculated regulatory level. The quantitation limit therefore becomes the regulatory level.
