What does TCLP mean for hazardous waste codes?

TCLP means Toxicity Characteristic Leaching Procedure, EPA Method 1311. It measures what a representative sample of the waste releases into an extract.

How do I decide a TCLP hazardous waste code?

Use the extract concentration in mg/L. Total content in mg/kg is a different measure, and it can't be converted into a TCLP result.

Manufactured gas plant waste is excluded from the toxicity characteristic under 261.24(a).

Where Table 1 footnote 3 applies, its measurement limit becomes the regulatory level.

If cresol isomers can't be measured separately, use D026 total cresol at 200 mg/L.
