HAZARDOUS WASTE Hazardous Waste Management at Bowling Green State University
Resource Conservationand Recovery Act (RCRA) - 1976 “Cradle to grave” management of hazardous wastes
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)
Six Steps of HazardousWaste Management • Identification • Collection • Storage • Packaging • Transportation • Disposal
HAZARDOUS WASTE Hazardous Waste Defined
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?
