RCRA Hazardous Waste (US, 40 CFR 261)

What is the RCRA waste code for Wastewater Treatment Sludge?

Industrial wastewater treatment sludges may be RCRA hazardous if they exceed contaminant thresholds (D004-D043). Many sludges are managed under Clean Water Act 503 rules rather than RCRA.

Also searched as: WWTP sludge, biosolids, treatment sludge

Which Code Applies?

RCRA classifies waste by source, process, and characteristics — not just material. Pick the row that matches how your wastewater treatment sludge arises; each coded row links to the full waste code definition under 40 CFR Part 261.

D008 D List

Treatment sludge with heavy metals

Toxicity characteristic waste - Lead at or above 5.0 mg/L (TCLP)

D006 D List

Treatment sludge with other contaminants

Toxicity characteristic waste - Cadmium at or above 1.0 mg/L (TCLP)

No code

Municipal biosolids (land application)

CWA 503 jurisdiction, not typically RCRA

Simulate your D008 stream

Wastewater Treatment Sludge

With a lab analysis, the engine checks the stream against each receiving route's published limits and returns what is supported, what is refused, and why. Without one yet, we tell you which routes it can evaluate and what analysis that needs.

What do you need?

An engineer replies within 1 business day. That reply confirms what is needed to run the dossier and when it can follow. A route the engine does not cover yet is reported as not yet evaluable, with the evidence that would change that.
