Hazardous Waste Management at Bowling Green State University HAZARDOUS WASTE
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 <1 Kg of acutely toxic waste per month) Conditionally Exempt Small Quantity Generators (CESQGs) (generate less than 100 Kg and<1 Kg of acutely toxic waste per month)
4
Six Steps of Hazardous Waste Management Identification Collection Storage Packaging Transportation Disposal
5
Hazardous Waste Defined HAZARDOUS WASTE
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 140 o F 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?

26
Storage area of last resort
27
Overcrowding?
28

30
Improper storage?
31
Storage (Departmental)
32
Transfer to safe storage areas
33

38
Partition areas within storage unit
39
Separation of incompatible chemicals
40

45
Comingling wastes in fume hood
46
Comingling wastes outside
47

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 of hazardous chemical with one that is less or non-hazardous Substitution
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
