Resource Conservationand Recovery Act (RCRA) -
1976

• Cradle to grave
• management of
• hazardous wastes

3
Hazardous and Solid Waste Amendments (HSWA) - 1984

• Established three categories of generators
• Large Quantity Generators (LQGs)
• (generate over 1000 Kg of hazardous waste per
  month)
• Small Quantity Generators (SQGs)
• (generate between 100 1000 Kg and lt1 Kg of
  acutely
• toxic waste per month)
• Conditionally Exempt Small Quantity Generators
  (CESQGs)
• (generate less than 100 Kg and lt1 Kg of acutely
  toxic
• waste per month)

4
Six Steps of HazardousWaste Management

• Identification
• Collection
• Storage
• Packaging
• Transportation
• Disposal

5
HAZARDOUS WASTE

• Hazardous Waste Defined

6
Hazardous Waste Categories

• Listed Wastes (U, P, K, and F)
• from commercial chemical products
• from specific and non-specific sources
• Characteristic Wastes (D)
• based on waste qualities
• heavy metals and certain pesticides

7
Listed Wastes (U, P) Commercial Chemicals

• U listed wastes (toxic)
• Acetone
• Formaldehyde
• Phenol
• P listed wastes (acutely toxic)
• Osmium Tetroxide
• Sodium Azide
• Sodium Cyanide

8
Listed Wastes (K, F) Specificand Nonspecific
Sources

• K listed wastes (specific sources)
• Distillation bottoms from the production of
  acetaldehyde from ethylene
• Wastewater treatment sludges generated in the
  production of creosote
• F listed wastes (non-specific sources)
• Spent halogenated solvents (e.g. carbon
  tetrachloride)
• Spent non-halogenated solvents (e.g. toluene, MEK)

9
Characteristic Wastes D Wastes

• Ignitable
• flash point ? 140oF
• Corrosive
• pH ? 2 or ? 12.5
• Reactive
• unstable
• air/water reactive
• Toxic
• heavy metals
• certain pesticides

10
Identification

• Who are the generators?
• What are they generating?
• How much are they generating?

Disposal

• Options
• EPA approved landfill
• deep well injection
• incineration
• other thermal destruction
• chemical treatment

Certificate of Treatment or Disposal
58
Waste Minimization Program

• inventory management
• substitution
• microquantities
• drain disposal
• neutralization
• recycling

59
Inventory Management
Purchase and store only those chemical quantities
to be used over a short period of time
60
Substitution
Substitution of hazardous chemical with one that
is less or non-hazardous
61
Use of Material Safety Data Sheets in selecting
potential chemicals for substitution
62
Microquantities
Use of smaller quantities of chemicals can
result in smaller volumes of hazardous wastes
63
Drain Disposal
Only for certain chemicals in small
quantities with appropriate dilution and POTW
approval
64
Elementary Neutralization
Proper neutralization of hazardous chemicals
can result in reduced hazardous waste generation
65
Recycling through Distillation
Solvent distillation reduces waste volumes
and and extends the time between needed purchases
66
OrphanChemical Program

• Transfers useable but unwanted chemicals to those
  who can use them
• reduces disposal costs
• reduces purchasing costs for new materials
