Classification

See the full D list

Wastes that are hazardous because of what they do, not where they come from: ignitability (D001), corrosivity (D002), reactivity (D003), or toxicity (D004-D043, defined by TCLP contaminant thresholds). Any industrial waste stream can carry a D code.

How D014 is handled

01

A D code is determined by testing, not by source: TCLP for toxicity (D004-D043), flash point for ignitability (D001), pH for corrosivity (D002).

02

Characteristic wastes can exit hazardous status when the characteristic is removed - treatment to below the regulatory level is a recognized compliance path.

03

Generators must count D-coded streams toward their monthly generator status (VSQG / SQG / LQG).

Other D-list codes

D001Ignitable waste - liquids with flash point below 60 C (140 F), ignitable solids, oxidizers, and ignitable compressed gasesD002Corrosive waste - aqueous wastes with pH at or below 2 or at or above 12.5, or liquids that corrode steel faster than 6.35 mm per yearD003Reactive waste - unstable, water-reactive, cyanide- or sulfide-bearing, or explosive wastesD004Toxicity characteristic waste - Arsenic at or above 5.0 mg/L (TCLP)D005Toxicity characteristic waste - Barium at or above 100.0 mg/L (TCLP)D006Toxicity characteristic waste - Cadmium at or above 1.0 mg/L (TCLP)D007Toxicity characteristic waste - Chromium at or above 5.0 mg/L (TCLP)D008Toxicity characteristic waste - Lead at or above 5.0 mg/L (TCLP)

Where can a D014 stream go?

Recognized recovery routes for this waste family, ranked by typical recovery tier. Which route fits depends on your specific stream — composition, volume and region.

High-temperature combustion

Specialist handling

Pesticide-bearing characteristic wastes carry combustion-based treatment standards; destruction at permitted high-temperature units is the established route for the organic load.

40 CFR 268.40 — LDR treatment standards

Energy recovery where fuel value exists

Low recovery

Streams with meaningful organic fuel content may qualify for burning for energy recovery in permitted industrial furnaces rather than pure destruction — dependent on halogen and metals limits.

40 CFR Part 266 Subpart H — burning for energy recovery

These are the typical routes for the D list. Your stream's actual options depend on its composition and where it sits.
