CHAPTER 15 TITLE
HAZARDOUS MATERIALS
A. LISTED WASTE
Resource Conservation and Recovery Act (RCRA)
The Resource Conservation and Recovery Act (RCRA), enacted in 1976, is the principal Federal law in the U.S. governing the disposal of solid waste and hazardous waste
LISTED WASTE
F-list
- From nonspecific sources or generic waste streams
K-list
- Fromspecificsources
P-list
- Acutelytoxichazardouswaste
U-list
- Commercial chemical products,
Was passed in 1975 to give the Department of Transportation (DOT) the authority to regulate the transportation of hazardous materials by air, waterways, rail, or highway
Hazardous Materials Transportation Act (HMTA)
- Was passed in 1976 by the Congress to give broad powers to the Environmental Protection Agency (EPA) to regulate the production and use of potentially hazardous chemicals and to ensure that new chemicals do not pose unreasonable hazards
Toxic Substances Control Act (TSCA)
- Was passed in 1976 by Congress to direct the Environmental Protection Agency (EPA) to implement a program that would ‘‘protect human health and the environment from improper hazardous waste management’’
Resource Conservation and Recovery Act (RCRA)
large companies producing more than 1000 kg of hazardous waste per month
Early regulations
Producers of between 100 - 1000 kg hazardous waste per month
Subsequent amendment
is something unwanted, usually a solid, liquid, or a contained gas.
It is the responsibility of the generator to determine if the waste is nonhazardous, hazardous, or acutely hazardous.
waste
EPA classifies waste as hazardous if, through improper handling, it can cause injury or death or can damage or pollute the environment.
Hazardous Waste
Section 40 CFR Part 261 – “Identification and Listing of Hazardous Waste.’’
- Listed Waste
- Characteristic Waste
Characteristic Wastes / TCLP Wastes / D Wastes
● Ignitable wastes
● Corrosive wastes
● Reactive wastes
● Toxic characteristic wastes
Ignitable wastes - have a flash point lower than 140 degrees Fahrenheit
● Corrosive wastes - are acidic (at or below a pH of 2) or caustic (at or above 12.5 pH)
● Reactive wastes - produce violent results when mixed with water, air, or other chemicals
● Toxic characteristic wastes - contain specified percentages of specific metals, pesticides, or organic chemicals
Wastes that exhibit any one of the four (4) mentioned characteristics are referred to as characteristic wastes or TCLP wastes and are coded as D wastes.
● They are discovered by testing the waste stream with the toxicity characteristic leaching procedure (TCLP).
● This test is used to determine the amount of chemical that would leach out into the groundwater under specific conditions.
TOXIC CHARACTERISTIC WASTES
● Once it has been determined the waste produced by a plant is hazardous, the facility becomes a hazardous waste generator.
● Total hazardous waste it generates per calendar month must be determined.
● The correct generator status is important because different regulations apply to each different status.
Determining Generator Status
Three Generator Status
Limited-quantity Generator
Small-quantity Generator
Large-quantity Generator
- Less than 100 kg of hazardous waste per month
- Not required to obtain an EPA identification number but most licensed waste haulers will require an EPA identification number to ship the waste off-site
Limited-quantity Generator
- Between 100-1000 kg of hazardous waste per month
- Required to obtain an EPA identification number
- They can accumulate up to 6,000 kilograms of hazardous waste in any 180-day period.
- If hazardous waste is to be transported more than 200 miles, the generator is allowed to accumulate up to 270 days.
Small-quantity Generator
- 1000 kg of hazardous or 1 kg of acutely hazardous waste per month
- If the hazardous waste must be transported more than 200 miles, the generator is allowed to accumulate hazardous waste for 180 days.
Large-quantity Generator
● A Notification of Hazardous Waste Activity (Form 8700-12) must be requested from the U.S. EPA or state EPA.
● If the facility is a treatment, storage, and disposal (TSD) facility, additional forms must be completed.
● Once the EPA has reviewed the form, a 12-character EPA ID number will be assigned to the facility.
Obtaining an EPA Identification Number
- In 1980, _____ was passed.
CERCLA: Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)
CERCLA, also known as___, gives the government authority to pursue potentially responsible parties (PRPs) for past and future cleanup costs at abandoned waste dumps and other places where hazardous substances have been released
Superfund
_____was proposed as a more stringent response to hazardous waste releases
Superfund Amendments and Reauthorization Act (SARA)
- Both SARA and CERCLA address hazardous substance releases into the environment and the cleanup of inactive hazardous waste disposal sites
- Under SARA, any company with threshold quantities of extremely hazardous substances (EHSs) must contact state and local emergency planners and the fire department
- Threshold quantities refer to specified amounts of certain chemicals. If the company has these chemicals, it must also submit copies of its Material Safety Data Sheets (MSDSs) to the fire department and emergency planners.
- If a company exceeds certain thresholds, it will have to submit chemical inventory forms to state and local firefighters
