Classification of Hazardous Wastes

Solid WastesHazardous Waste DefinitionUsed OilOther Waste Characterization

PrinciplesUsed, Reused, Reclaimed, RecycledDelisting


Solid Wastes: can be a solid liquid or gas a material must first be a solid waste before

it can be classified a hazardous waste A material that has been abondoned through

disposal, burning, storage, or treatment, or recycled (including use, reuse, reclamation)


Hazardous Wastes: First step. Is it specifically exempted? Not a solid waste:

untreated sanitary sewage going to POTWPoint Source Discharge Permits (lagoon too)irrigation return flows

There are other very specific exemptions:nuclear wastespulping liquorsmining wastes


Solid Wastes that are not hazardous wastes: Household wastes Ag waste if used as fertilizer Mining spoils return to mine Wastes from exploration, development or

production of crude oil, gas, geothermal Cement Kiln wastes Leather Industry, Trivalent Chromium

Process


Some Hazardous Solid Wastes are regulated by other laws: Asbestos - CAA/NESHAP PCBs above 50ppm - TSCA

Only Two ways a solid waste can be a hazardous waste: the waste is specifically listed as hazardous the waste ails a characteristic test


Listed Hazardous Wastes: EPA has authority to generally lists

wastes it believes are hazardous The waste may be delisted if you can

prove that it meets delisting criteria Delisting is granted by specific material,

process and address. Delisting will be covered later


EPA lists wastes based on three categories: Exhibits a hazardous characteristic

ignitibility, reactivity, corrosivity, toxicity

Acutely hazardous fatal to humans at low doses

ToxicIf it contains certain hazardous constituents.

Listing is accompanied by a hazard codeI, C, R, E, H, T


There are three lists of hazardous wastes Non Specific Source Wastes Specific Source Wastes Discarded Commercial Chemical Products

Non Specific Source Wastes Broad, General Groupings (F series)

Spent SolventsElectroplating/Metal FinishingOther Non Specific


Specific Source Wastes Wastes from certain industries that EPA has

defined as hazardousK series wasteswood preservation, organic chemicals, cokingpesticides, explosives, ink formulation, etc

Discarded Comm. Products (U/P series) Listed in 261.33(e)(f), (very narrow) or its sole active ingredient is listed here, and this material is discarded for any reason.


Hazardous Waste Characteristics Ignitability Corrosivity Reactivity Toxicity


Ignitability Applies to any physical state Most common is Liquids (fp <140F) Excludes Aqueous Alcohol if <24% Other ignitable wastes include:

DOT oxidizersSpontaneously CombustibleDOT flammable compressed gases

Assigned EPA HW# D0001


Corrosivity Applies only to Liquids

If unsure about physical state do a paint filter liquids test

pH is greater than 12.5 or less than 2.0 or it corrodes steel at 6.35 mm/year Assigned EP # D0002


Reactivity (D0003) The most Nebulous characteristic No repeatable, sound test method Meant to identify wastes that have the

potential to explode or release toxic gases during the waste management process

The determination is based ultimately on the your knowledge of your waste and a regulatory interpretation.


The regulatory language normally unstable, undergoes violent change reacts violently with water forms explosive mixtures with water explosive if heated under confinement detonates, explosive decomposition, or

reaction at standard T and P is a DOT forbidden, A, or B, explosive cyanide and sulfide available for release


Toxicity Characteristic (TC) The TC is based on the results of the TCLP. Extraction by DI water and acetic acid 8 heavy metals, 4 insecticides, 2 herbicides,

and 25 other organic compounds Extraction in analyzed to determine if any of

these 39 compounds exceed their MCL Assigned EPA# D0004-D043


TC Exemptions If the waste contains PCB that meets the

TSCA Wastes that meet the MCL for Chromium if

waste not otherwise listed and < other MCLs waste and process is trivalent chromium waste is managed in non oxidizing environments

TCLP Shortcut (if waste contains less than 20 times MCL of a contaminant, the dilution extraction CAN NOT exceed the MCL


Other Classification Rules: non-listed wastes carry the EPA#’s for each of the

characteristics it exhibits listed wastes that also meet a characteristic code,

are classified by all codes, but a listed waste does not carry the waste number

for the characteristics it was listed for

Samples sent for analysis are not classed as Hazardous Wastes if they are packaged to prevent leaks and vaporization


Used Oil (six questions): Is it used oil (crude or synthetic used as oil) Is the used oil mixed with a HazWaste Does the oil contain >1000ppm halogens Is it used oil fuel Is it a hazardous waste fuel Is the used oil fuel, specification used oil

fuelAr, Cd, Cr, Pb, FP>100F, Halogen <4000ppm


Empty Containers all material commonly possible removed,

and no more than iI” residue on the bottom, or residue is less than 3% by weight <110G residue is less than 0.3% by weight >110G Unless the drum contained an acute

hazardous material or H series waste,then removed lining or triple rinsed.


Mixture Rule a characteristic waste mixed with a

solid waste is a hazardous waste if it exhibits a characteristic

a listed waste mixed with a solid waste is always a hazardous waste, unlessthe listed waste is listed only because of a

characteristic and the mixture exhibits a characteristic.
