Regulation
30 TAC §335.521(c)
Under 30 TAC §335.503 every Texas industrial waste stream is coded with an 8-digit waste code: a 4-character sequence number assigned by the generator, this 3-digit form code, and a 1-character classification.
HHazardous Waste
Waste that is listed or characteristic hazardous waste under the federal RCRA rules (40 CFR Part 261), as adopted by reference in Texas. Carries EPA waste codes (D, F, K, P, U) alongside the Texas code.
1Class 1 Industrial Waste
Nonhazardous industrial waste that is potentially threatening: Class 1 toxic constituents at or above maximum leachable concentrations, ignitable (liquid flash point below 150 F or readily ignitable solid), corrosive (pH 2 or below, or 12.5 or above), 20 ppm or more total recoverable cyanides, or lacking the data to prove a lower class.
2Class 2 Industrial Waste
The default nonhazardous class: any industrial solid waste that does not meet the definition of hazardous, Class 1, or Class 3. Most routine industrial waste streams classify as Class 2.
3Class 3 Industrial Waste
Inert and essentially insoluble industrial waste posing no threat to human health or the environment: rock, brick, glass, dirt and certain plastics and rubber. Requires leachate testing showing no exceedances and no detectable TPH or PCBs.
A waste stream carrying form code 206 can classify as any of the four, depending on its constituents. Classification H streams also carry federal RCRA waste codes.
Solvent-bearing and oily liquid streams: halogenated and non-halogenated solvents, oil-water emulsions, waste oil, paint and ink liquids, thinners and PCB-bearing liquids.
Recognized recovery routes for this waste family, ranked by typical recovery tier. Which route fits depends on your specific stream — composition, volume and region.
Solvent-bearing liquid streams are prime reclamation candidates: distillation recovers a technical-grade solvent for reuse, with only the still bottoms remaining as waste.
40 CFR 261.1(c)(4) — reclamationWaste oil and oily liquids route into the used-oil management system, where re-refining returns base oil to the lubricant market — a mature, established recovery chain.
40 CFR Part 279 — used oil management standardsOrganic-bearing streams with usable fuel value can be blended and burned for energy recovery in permitted boilers and industrial furnaces instead of being managed as pure disposal.
40 CFR Part 266 Subpart H — burning for energy recoveryThese are the typical routes for organic liquids. Your stream's actual options depend on its composition and where it sits.
