classification of hazardous wastes
Classification of Hazardous Wastes
  • Solid Wastes
  • Hazardous Waste Definition
  • Used Oil
  • Other Waste Characterization Principles
  • Used, Reused, Reclaimed, Recycled
  • Delisting
classification of hazardous wastes3
Classification of Hazardous Wastes
  • 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)
classification of hazardous wastes4
Classification of Hazardous Wastes
  • Hazardous Wastes:
    • First step. Is it specifically exempted?
    • Not a solid waste:
      • untreated sanitary sewage going to POTW
      • Point Source Discharge Permits (lagoon too)
      • irrigation return flows
    • There are other very specific exemptions:
      • nuclear wastes
      • pulping liquors
      • mining wastes
classification of hazardous wastes5
Classification of Hazardous 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
classification of hazardous wastes6
Classification of Hazardous Wastes
  • 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
classification of hazardous wastes7
Classification of Hazardous Wastes
  • 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
classification of hazardous wastes8
Classification of Hazardous Wastes
  • EPA lists wastes based on three categories:
    • Exhibits a hazardous characteristic
      • ignitibility, reactivity, corrosivity, toxicity
    • Acutely hazardous
      • fatal to humans at low doses
    • Toxic
      • If it contains certain hazardous constituents.
    • Listing is accompanied by a hazard code
      • I, C, R, E, H, T
classification of hazardous wastes9
Classification of Hazardous Wastes
  • 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 Solvents
      • Electroplating/Metal Finishing
      • Other Non Specific
classification of hazardous wastes10
Classification of Hazardous Wastes
  • Specific Source Wastes
    • Wastes from certain industries that EPA has defined as hazardous
      • K series wastes
      • wood preservation, organic chemicals, coking
      • pesticides, 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.
classification of hazardous wastes11
Classification of Hazardous Wastes
  • Hazardous Waste Characteristics
    • Ignitability
    • Corrosivity
    • Reactivity
    • Toxicity
classification of hazardous wastes12
Classification of Hazardous Wastes
  • Ignitability
    • Applies to any physical state
    • Most common is Liquids (fp <140F)
    • Excludes Aqueous Alcohol if <24%
    • Other ignitable wastes include:
      • DOT oxidizers
      • Spontaneously Combustible
      • DOT flammable compressed gases
    • Assigned EPA HW# D0001
classification of hazardous wastes13
Classification of Hazardous Wastes
  • 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
classification of hazardous wastes14
Classification of Hazardous Wastes
  • 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.
classification of hazardous wastes15
Classification of Hazardous Wastes
  • 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
classification of hazardous wastes16
Classification of Hazardous Wastes
  • 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
classification of hazardous wastes17
Classification of Hazardous Wastes
  • 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
classification of hazardous wastes18
Classification of Hazardous Wastes
  • 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
classification of hazardous wastes19
Classification of Hazardous Wastes
  • 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 fuel
      • Ar, Cd, Cr, Pb, FP>100F, Halogen <4000ppm
classification of hazardous wastes20
Classification of Hazardous Wastes
  • 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.
classification of hazardous wastes21
Classification of Hazardous Wastes
  • 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, unless
      • the listed waste is listed only because of a characteristic and the mixture exhibits a characteristic.
