HAZARDOUS WASTE Hazardous Waste Management at Bowling Green

HAZARDOUS WASTE Hazardous Waste Management at Bowling Green State University

Resource Conservation and 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 Hazardous Waste 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) – 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)

Characteristic Wastes – “D” Wastes Ignitable • flash point 140 o. F Corrosive • p. H 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?

Use of placards as required

Use of Uniform Hazardous Waste Manifest system

Disposal • Options – EPA approved landfill – deep well injection – incineration – othermal destruction – chemical treatment

Aptus hazardous waste incinerator Coffeeville, Kansas

Certificate of Treatment or Disposal

Waste Minimization Program • inventory management • substitution • microquantities • drain disposal • neutralization • recycling

Inventory Management Purchase and store only those chemical quantities to be used over a short period of time

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

Use of Material Safety Data Sheets in selecting potential chemicals for substitution

Microquantities Use of smaller quantities of chemicals can result in smaller volumes of hazardous wastes

Drain Disposal Only for certain chemicals in small quantities with appropriate dilution and POTW approval

Elementary Neutralization Proper neutralization of hazardous chemicals can result in reduced hazardous waste generation

Recycling through Distillation Solvent distillation reduces waste volumes and extends the time between needed purchases

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