RCRA Hazardous Waste (US, 40 CFR 261)
Paint waste may be hazardous if it exhibits ignitability (D001 if flash point below 60C) or contains lead/chromium above TCLP thresholds (D008/D007). Water-based paints with no hazardous constituents may not be RCRA hazardous.

Have a D001 stream? See the dossier that replaces the feasibility study.
See the validation dossierRCRA classifies waste by source, process, and characteristics — not just material. Pick the row that matches how your paint waste arises; each coded row links to the full waste code definition under 40 CFR Part 261.
Solvent-based paint (typically ignitable)
Ignitable waste - liquids with flash point below 60 C (140 F), ignitable solids, oxidizers, and ignitable compressed gases
Paint containing lead (above 5.0 mg/L TCLP)
Toxicity characteristic waste - Lead at or above 5.0 mg/L (TCLP)
Paint containing chromium (above 5.0 mg/L TCLP)
Toxicity characteristic waste - Chromium at or above 5.0 mg/L (TCLP)
Water-based paint without hazardous constituents
May not be RCRA hazardous; check TCLP

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.
