Possible Dangerous Waste Codes

Derived from the Toxicity Characteristic Leaching Procedure (TCLP) test results or knowledge based on a label.

D004 - if there were enough arsenic to leach 5.0 or more milligrams per liter.
D007 - if there were enough chromium to leach 5.0 or more milligrams per liter.
D008 - if there were enough lead to leach 5.0 or more milligrams per liter. EPA has reported that arsenic used in the wood preserving formulations was typically contaminated with lead (see the December 30, 1988 Federal Register Vol. 53 No. 251 page 53284).
D023 - if there were enough o-Cresol to leach 200.0 or more milligrams per liter.
D024 - if there were enough m-Cresol to leach 200.0 or more milligrams per liter.
D025 - if there were enough p-Cresol to leach 200.0 or more milligrams per liter.
D026 - if there were enough total cresol to leach 200.0 or more milligrams per liter. If 0-, m-, and p-Cresol concentrations cannot be differentiated, the total cresol (D026) concentration is used.
D037 - if there were enough pentachlorophenol to leach 100.0 or more milligrams per liter.

WT01 or WT02 Washington State only dangerous waste codes derived from a Washington State Toxicity Criteria Test or book designation based on other test results such as a total arsenic, chromium, lead, and cresol.
