HUD Ch. 10: Hazardous & Non-Hazardous Waste Flashcards
If waste is a result of _________ __________, it may be exempt from hazardous waste regulations
interim control
Category I
Low Lead Waste (typically nonhazardous)
Ex:
- Filtered personal & commercial wash water
- Disposable personal protective clothing that has been HEPA vacuumed before disposal
- Plastic sheeting cleaned prior to disposal & carpeting
- ANy waste that is determined to be nonhazardous by TCLP testing & is not an EPA-listed hazardous waste
Category II
Architectural Components
Ex:
- Painted finish carpentry items (doors, windows, baseboards, etc.)
- Other painted building components (metal railings, radiators, stone or brick, etc.)
Category III
Concentrated Lead Waste (typically hazardous)
Ex:
- Sludge from paint stripping
- Lead-based paint chips and dust
- HEPA vacuum debris and filter
- Unfiltered wash water
- Hazardous waste
- Any waste included in EPA list
Category IV
Other Waste
Material that cannot be determined, using knowledge of the waste, to be either hazardous or nonhazardous must be tested using the TCLP
RCRA Subtitle C defines generator as ____________________
Any person at a particular facility or location whose act or process produces hazardous waste.
To determine hazardous waste, generators must answer the following questions:
- Does the generator have knowledge that waste is hazardous under RCRA regulations?
- Did a test define the material as RCRA waste (characteristic hazardous waste)?
- Is the waste exempt from regulation as “hazardous” under RCRA rules?
- Is the waste included on EPA’s hazardous waste list?
- If hazardous or nonhazardous, what Federal, State, or local standards must be satisfied?
Toxicity, Corrosivity, Ignitability, & Reactivity are all _________ and considered _________
characteristics; hazardous
Waste toxicity is measured by using the __________________to determine if it is above the allowable TC regulatory threshold for lead (5ppm)
Toxicity Characteristic Leaching Procedure (TCLP)
Paint chip analysis should only be used to determine specific lead compound present if __________
- The total lead level is very low (<100 ppm), indicating that waste should not exceed the TC threshold.
- Total lead levels can be used in combination with total waste volume estimates to determine whether recycling for lead recovery is feasible.
Corrosive waste has a pH that is ___________
= 2 (highly acidic) OR >/=12.5 (highly basic)
Ex: Unneutralized caustic paint strippers & acidic paint strippers
Includes liquids with flash points < 140 F
Ignitable Waste
Ex: Certain solvents from paint strippers & the resulting sludge
Substances capable of easily generating explosive or toxic gases, especially when mixed with water
Reactive Waste
Lead-based paint hazard projects are unlikely to produce this kind of waste.
Interim waste may be exempt from RCRA hazardous waste regulations if it meets the following 2 criteria:
- Must be generated by individuals on the premises of a household.
- Waste must be composed primarily of materials found in waste generated by consumers in their home.
If significant quantities of waste water are produced, (>10 gallons), owners should _____________
contact the local waste water treatment facility before discharging the liquid to determine if there are any specific pretreatment standards to be implemented
If dwelling is being partially or completely renovated or demolished as part of lead hazard control work, the categories of abatement waste _______
Do not apply
HUD recommendations for nonhazard abatement waste:
- Should be wrapped in 6 mil poly, all seams sealed with tape during storage & transport
- Stored in designated locked area
- Liquid waste should be disposed in toilet after applicable pretreatment steps (filtering, gravitational separation)
- Dumpsters should have lids and be padlocked
When cleaning work area, 1. __________, 2. Remove 1st layer of poly, 3. ___________, 4. Remove 2nd layer of ploy, 5. __________
- HEPA vacuum
- Wash all surfaces with lead cleaner
- HEPA vacuum all surfaces again
A hazardous waste manifest must be completed before waste is shipped offsite
AND
Generators must apply for and obtain an EPA identification number prior to shipping the hazardous waste offsite if _________
more than 100 kg per month (220 lbs) of hazardous waste is likely to be produced.
Likely for all multi-family dwelling abatement projects and my apply to single family dwelling abatement projects.
Generators qualify as conditionally exempt small quantity generators if _________
less than 100 kg per month of hazardous waste is produced.
At a minimum must be disposed of in State-licensed or permitted solid waste management facilities or hazardous waste disposal facilities
If significant quantities of waste water are created (>100 gallons), _________________
The local water treatment facility should be contacted to determine if special measures should be taken before the waste water is poured down the toilet.
The household waste exemption for interim control does not apply to _______
Public buildings
Small quantity generator
Generators producing quantities between 100-1000kg/month.
Are “conditionally exempt”
Large quantity generator
Generator producing quantities greater than 1,000kg/month
Small quantity generators may accumulate up to _______kg of hazardous waste onsite for 180 days or 270 days if treatment storage or disposal site is more than 200 miles away
6,000 kg (13,200 lbs)
Large quantity generators may store waste onsite for______days
90 days
Waste must be placed in containers, or
placed on drip pads, or
placed in a containment building
Small & large quantity generators must label stored hazardous waste and indicate ______ _______ _____
accumulation start date
_______ quantity generators must have a written emergency plan
Large
Abatement projects producing hazardous lead waste containing particles that will pass through a ______mm sieve must meet land disposal restrictions for RCRA hazardous waste code D008
60 mm (2.5 inches)
D008 waste must be ________before it is sent to a hazardous waste landfill
treated
Manifests, results of hazardous waste testing, and land disposal notifications/certifications for _____years, but for liability reasons, records should be kept for _____years
3; 10
