RCRA Hazardous Waste (US, 40 CFR 261)

What is the RCRA waste code for Antifreeze & Coolant?

Used antifreeze may be hazardous if it contains lead or exhibits toxicity characteristics. Many modern coolants are not RCRA hazardous, but used automotive coolant is often assumed hazardous and characterized.

Also searched as: engine coolant, glycol coolant, vehicle coolant, radiator fluid

Which Code Applies?

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

D008 D List

Antifreeze with lead (above 5.0 mg/L TCLP)

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

D006 D List

Antifreeze with other heavy metals

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

No code

Modern lead-free antifreeze

May not be RCRA hazardous but verify TCLP

Simulate your D008 stream

Antifreeze & Coolant

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.
