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 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?

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

Substitution

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

and 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
