Hazardous Waste Classification in California

• Corey Yep
• Waste Identification and Recycling Section
• State Regulatory Programs Division
• Hazardous Waste Management Program
• Department of Toxic Substances Control

2
Purpose of Course

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

3
Objectives

• Understand the term waste
• Understand exclusions and exemptions that may
  apply
• Understand what the hazardous waste listings and
  characteristics are

4
Waste Classification Requirements

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

5
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.ht
  m)

6
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/)

7
State Requirements

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

8
California is a federally authorized state

• Generally, Californias requirements contain all
  hazardous waste requirements that apply in
  California
• Most newly adopted federal regulations do not
  apply in California until California adopts them

9
Definition of Hazardous Waste 25117 HSC

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

10
Hazardous Waste Criteria25141 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

63
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

  in the waste, then the maximum extractable
  concentration result would be

• TCLP 1/20 the total concentration

65
Example

• 530 mg/kg total lead concentration, the maximum
  soluble results would be

71
Waste Classification Process

• Mixtures
• Characteristic
• RCRA Listed
• Derived From
• Contained In

72
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)

73
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)

74
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)
