Hazardous Waste Management
at
Bowling Green State University
HAZARDOUS
WASTE
Resource Conservationand Recovery Act (RCRA) - 1976
“Cradle to grave”management of
hazardous wastes
Hazardous and Solid Waste Amendments (HSWA) - 1984Established 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)
Six Steps of HazardousWaste Management
• Identification• Collection• Storage• Packaging• Transportation• Disposal
Hazardous Waste Defined
HAZARDOUS
WASTE
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
Listed Wastes (U, P) –Commercial Chemicals
“U” listed wastes (“toxic”)• Acetone• Formaldehyde• Phenol
“P” listed wastes (“acutely toxic”)• Osmium Tetroxide• Sodium Azide• Sodium Cyanide
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)
Characteristic Wastes – “D” Wastes
Ignitable• flash point 140oF
Corrosive• pH 2 or 12.5
Reactive• unstable• air/water reactive
Toxic• heavy metals• certain pesticides
Identification
• Who are the generators?• What are they generating?• How much are they generating?

Unknowns
• Unnecessary• Expensive to identify
Collection
Use of funnel foradditions to wastecontainer
Lid of waste container secured following additions
Properly labeled
Storage(Lab)
Proper waste storage
Proper waste storage
Separate, safe areas with instructions

Improper storage?
Storage(Departmental)
Transfer to safe storage areas

Transportation(On-site)
Hazardous waste transport vehicle
Waste storage unit
Partition areas within storage unit
Separation of incompatible chemicals
Hazardous WasteStorage Facility
(HWF)
Storage on wooden shelving withinindividual storage rooms
Packaging
DOT approvedcontainers
Comingling wastesin fume hood
Comingling wastes outside
Lab-packing chemicalsin 55-gallon drum
Proper labeling of waste drums
Proper labeling of waste pails
Transportation(Off-site)
EPA registered transport vehicle
Proper loading of waste containers
Use of placards as required
Use of UniformHazardous WasteManifest system
Disposal
• Options– EPA approved landfill– deep well injection– incineration– other thermal destruction– chemical treatment
Aptus hazardous waste incineratorCoffeeville, Kansas
Certificate ofTreatmentor Disposal
Waste Minimization Program
• inventory management• substitution• microquantities• drain disposal• neutralization• recycling
Inventory Management
Purchase and store only those chemicalquantities to be used over a short period of time
Substitution of hazardous chemicalwith one that is less or non-hazardous
Substitution
Use of MaterialSafety Data Sheets inselecting potentialchemicals forsubstitution
Microquantities
Use of smaller quantities of chemicals can resultin smaller volumes of hazardous wastes
Drain Disposal
Only for certain chemicals in small quantitieswith appropriate dilution and POTW approval
Elementary Neutralization
Proper neutralization of hazardous chemicals canresult in reduced hazardous waste generation
Recycling through Distillation
Solvent distillation reduces waste volumes andand extends the time between needed purchases
OrphanChemical Program
• Transfers useable but unwanted chemicals to those who can use them
• reduces disposal costs• reduces purchasing costs for new
materials
