Title: Hazardous Waste Management at Bowling Green State University


1
HAZARDOUS WASTE
Hazardous Waste Management at Bowling Green
State University
2
Resource Conservation and 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 Hazardous Waste 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) Specific and 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?

11
Academic Labs
12
Research Labs
13
Custodial Closets
14
Other Custodial Storage Areas
15
Building Maintenance Areas
16
Paint Shops
17
Unknowns
  • Unnecessary
  • Expensive to identify

18
Collection
19
Use of funnel for additions to waste container
20

additions Properly labeled
21

37
Waste storage unit
38
Partition areas within storage unit
39
Separation of incompatible chemicals
40
Hazardous Waste Storage Facility (HWF)
41
(No Transcript)
42
Storage on wooden shelving within individual
storage rooms
43
Packaging
44
DOT approved containers
45
Comingling wastes in fume hood
46
Comingling wastes outside
47
Lab-packing chemicals in 55-gallon drum
48
Proper labeling of waste drums
49
Proper labeling of waste pails
50
Transportation (Off-site)
51
EPA registered transport vehicle
52
Proper loading of waste containers
53
Use of placards as required
54
Use of Uniform Hazardous Waste Manifest system
55
Disposal
  • Options
  • EPA approved landfill
  • deep well injection
  • incineration
  • other thermal destruction
  • chemical treatment

56
Aptus hazardous waste incinerator Coffeeville,
Kansas
57
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
Orphan Chemical Program
  • Transfers useable but unwanted chemicals to those
    who can use them
  • reduces disposal costs
  • reduces purchasing costs for new materials
