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 602 can classify as any of the four, depending on its constituents. Classification H streams also carry federal RCRA waste codes.
Still bottoms, oily sludge, paint and ink sludge, tars and resins, biological treatment sludges, grease and petroleum-contaminated sludges.
Recognized recovery routes for this waste family, ranked by typical recovery tier. Which route fits depends on your specific stream — composition, volume and region.
Organic-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 recoveryOily sludges and still bottoms with recoverable oil content route through used-oil processors for oil recovery before the residual solids are treated.
40 CFR Part 279 — used oil management standardsBelow economic recovery concentrations, stabilization to the applicable treatment standard followed by controlled disposal remains the default management route.
40 CFR 268.40 — LDR treatment standardsThese are the typical routes for organic sludges. Your stream's actual options depend on its composition and where it sits.
