Purpose of Course

• To introduce the basic concepts of
  hazardous waste classification
  criteria in California




                                       2
Objectives
• Understand the term “waste”
• Understand exclusions and
  exemptions that may apply
• Understand what the hazardous
  waste listings and characteristics
  are
                                       3
Waste Classification
Requirements

• Two sets of standards in CA
  –Federal requirements
  –State requirements

                                4
Federal Requirements

• Statute: Chapter 42, United States
  Code (Resource Conservation and
  Recovery Act or RCRA)
    • (on line at http://uscode.house.gov/usc.htm)

• Regulations: Title 40, Code of
  Federal Regulations (40 CFR)
    • (on line at
      http://www.epa.gov/epahome/cfr40toc.htm)
                                                     5
State Requirements

• Statute: California Health and
  Safety Code, Division 20, Chapter
  6.5, Hazardous Waste Control Law
    • (on line at
      http://www.leginfo.ca.gov/calaw.html)

• Regulations: California Code of
  Regulations, Division 4.5, Title 22
    • (on line at http://www.calregs.com/)
                                              6
State Requirements

• Important Note: Unlike the federal
  requirements, in California both
  statutes and regulations contain
  specific requirements




                                       7
 California is a federally
 “authorized” state
• Generally, California’s requirements
  contain all hazardous waste
  requirements that apply in California
• Most newly adopted federal
  regulations do not apply in California
  until California adopts them
                                          8
 Definition of Hazardous Waste
 §25117 HSC

• Hazardous Waste
  – waste that meets criteria adopted by
    DTSC pursuant to § 25141 HSC
  – includes RCRA hazardous wastes



                                           9
 Hazardous Waste Criteria
 §25141 HSC
• Criteria shall identify wastes because of its
  quantity, concentration, or physical, chemical or
  infectious characteristics
  – causes or significantly contributes to an increase in
    mortality, serious irreversible or incapacitating
    reversible illness
  – pose substantial present or potential hazard to
    human health or the environment, due to
    …carcinogenicity, acute or chronic toxicity,
    bioaccumulative properties, or persistence in the
    environment, when improperly treated, stored,
    transported, or disposed of, or otherwise managed 10

Waste Classification Process



Waste Identification



                               13
 Overview of the waste
 classification process
• Is the material a waste?
  – Is the material excluded or exempted?
• Is the waste excluded or exempted?
• Is the waste listed in Article 4?
• Is the waste listed in Appendix X?
• Does the waste exhibit a
  characteristic of hazardous waste?
                                        14
Waste: Layperson’s definition

• A material that has been used or
  has otherwise served its intended
  purpose and, for whatever reason
  (contaminated, spent, or intent)
  can or will no longer be used for
  its intended purpose

                                      15

Overview of hazardous waste
classification
• Is the material a waste?
  – Is the material excluded or exempted?
• Is the waste excluded or exempted?
• Is the waste listed in Article 4?
• Is the waste listed in Appendix X?
• Does the waste exhibit a
  characteristic of hazardous waste?
                                        41
Listed Hazardous Wastes
22 CCR Article 4
• A waste is compared to the wastes
  described in the list
• The source of the waste (i.e., the
  process that generated the waste) is
  more important than the waste’s
  characteristics or constituents
• must meet all conditions of the listing
                                            42
Three categories of lists

1. Non-specific sources (F)

2. Specific sources (K)

3. Discarded commercial chemical
  products, off-specification species,
  and spill residues (P, U)

Appendix X
• List of 791 chemicals
• List of 66 common names or types of
  hazardous wastes
• List creates a “presumption”
• Wastes listed or containing a listed
  chemical are presumed hazardous
• Can be classified as nonhazardous using
  testing or knowledge, as with other
  wastes                                 45

Federal Toxicity Characteristic
22 CCR §66261.24(a)(1)
• Each constituent has a Regulatory
  Threshold (RT)
• If the measured concentration in the
  TCLP extract equals or exceeds the RT,
  the waste is toxic and hazardous
• Wastes hazardous for a particular
  constituent are identified by that waste
  code
                                         58
Persistent and Bioaccumulative
Toxic Substances
22 CCR §66261.24(a)(2)
• Inorganic constituents
  – Both WET soluble and total
    concentrations
• Organic constituents
  – Both WET soluble and total
    concentrations
                                 59

Persistent and Bioaccumulative
Toxic Substances
22 CCR §66261.24(a)(2)
• Toxic and hazardous if
• > Soluble Threshold Limit Concentration
  (STLC) by the WET (mg/L)
• > Total Threshold Limit Concentration
  (TTLC) by analysis for total
 concentration in waste (mg/kg)
                                        62
WET versus TCLP
• Relationship between total
  concentrations and WET and TCLP
  methods
• WET method involves a 10-fold dilution
  of waste to extractant fluid of solid
  portion of waste
• TCLP method involves a 20-fold dilution
  of waste to extractant fluid of solid
  portion of waste                       63
WET versus TCLP

• If the chemical in a solid waste is
  100% soluble in the waste, then
  the maximum extractable
  concentration result would be:
  – WET: 1/10 the total concentration
  – TCLP: 1/20 the total concentration

                                         64
Example
• 530 mg/kg total lead concentration,
  the maximum soluble results would
  be
  – WET: 53 mg/l
  – TCLP: 26.5 mg/l

• Both federal and state soluble
  thresholds for lead are 5 mg/l
                                    65

Waste Classification Process


• Mixtures
  – Characteristic
  – RCRA Listed
• Derived From
• Contained In
                               71
Mixture Rule
• Characteristic HW - nonRCRA and RCRA
  – Evaluate the mixture for hazardous waste
    characteristics
  – Intentional mixture to avoid regulation is
    treatment, and requires authorization
• Listed HW Mixtures
  – RCRA listed hazardous wastes mixtures are
    hazardous wastes
  – concentrations are irrelevant
• Exemptions
  – delisted or listed only for characteristic (ex. F003)

                                                        72
Derived From Rule
• Wastes derived from the treatment,
  storage or disposal
   – Characteristic Wastes
    • Evaluate the mixture for HW characteristics
    • RCRA or nonRCRA characteristic
  – RCRA Listed Wastes
    • hazardous waste, even if treatment destroyed
      chemicals of concern
    • Exemption - delisted or listed only for
      characteristic (ex. F003)
                                                     73
 Contained-in Policy
• Applies to contaminated media and
  debris
• Environmental media (water or soil)
  that contain listed wastes are
  hazardous wastes
  – unless it is demonstrated that the listed
    waste is present in insignificant
    concentrations (risk-based evaluation)
                                           74
