Characteristic hazardous waste
Cresol

Cresol at 200 mg/L or more in the TCLP extract.

Toxic characteristic waste. Waste with total cresol at 200 mg/L or more in the TCLP test. It covers cresol isomers not split out.

Is D026 hazardous waste?

Yes. D026 is hazardous waste when the o-, m- and p-cresol results can't be told apart and total cresol in the TCLP extract of a representative sample is 200 mg/L or more. That combined-cresol condition is part of the code.

Compare total cresol in the TCLP extract with 200 mg/L, and only when the 3 isomers can't be told apart.

D026 is a nonacute characteristic. On a required hazardous waste manifest, put D026 in Item 13. See VSQG exemptions and empty-container rules.

What does D026 cover?

D026 applies when the o-, m- and p-cresol results can't be told apart and total cresol in the TCLP extract is 200 mg/L or more. It is the combined-cresol route, not a single-isomer result.

Regulatory level: 200 mg/L in TCLP extract
Hazard: T, toxic
Rule: 40 CFR 261.24

Is cresol waste D026, D023, D024 or D025?

Code	When it fits
D026	The cresol isomers cannot be differentiated, and total cresol in the TCLP extract is at least 200 mg/L.
D023	The isomers can be differentiated, and the o-cresol TCLP result is at least 200 mg/L.
D024	The isomers can be differentiated, and the m-cresol TCLP result is at least 200 mg/L.
D025	The isomers can be differentiated, and the p-cresol TCLP result is at least 200 mg/L.

Generators decide the codes from testing or knowledge of the waste, under 40 CFR 262.11. A result below 200 mg/L rules out D026 only. It doesn't make the waste nonhazardous. The table’s cresol footnote decides whether an isomer code or D026 records the result.

Which wastes take D026?

Waste	When it’s D026
Contaminated soil	Cresol leaching from contaminated soil reaches the TCLP limit
Demolition debris	Cresol leaching from demolition debris reaches the TCLP limit
Treated wood waste	Cresol leaching from treated wood waste reaches the TCLP limit

D021	Chlorobenzene
D022	Chloroform
D027	1,4-Dichlorobenzene
D028	1,2-Dichloroethane
D029	1,1-Dichloroethylene
