CAR Appliance Recycler Environmental Compliance 2 — Questions and Answers
Question 1: Under the Clean Air Act Section 608, what is the required action before disposing of an appliance containing CFC refrigerants?
- Vent the refrigerant to the atmosphere
- Recover the refrigerant using certified equipment (Correct answer)
- Neutralize the refrigerant with a chemical agent
- Seal the appliance and label it as hazardous
Correct answer: Recover the refrigerant using certified equipment
Section 608 requires technicians to recover refrigerants using EPA-certified recovery equipment before disposing of any appliance.
Question 2: Which federal agency is primarily responsible for regulating the disposal of mercury-containing switches found in appliances?
- OSHA
- DOT
- EPA (Correct answer)
- CPSC
Correct answer: EPA
The EPA regulates mercury-containing devices under the Resource Conservation and Recovery Act (RCRA) and other federal environmental laws.
Question 3: What is the primary environmental concern with polychlorinated biphenyls (PCBs) found in older capacitors of appliances?
- They deplete the ozone layer
- They are persistent bioaccumulative toxins that contaminate soil and water (Correct answer)
- They contribute directly to greenhouse gas emissions
- They cause immediate combustion risk
Correct answer: They are persistent bioaccumulative toxins that contaminate soil and water
PCBs are persistent organic pollutants that accumulate in ecosystems and pose serious health risks to humans and wildlife.
Question 4: A recycler receives a refrigerator with an unknown foam insulation type. What is the safest compliance approach?
- Shred immediately since foam poses no known risk
- Test or assume it contains HCFC-141b blowing agents and handle accordingly (Correct answer)
- Treat it as non-hazardous until proven otherwise
- Landfill the foam component without processing
Correct answer: Test or assume it contains HCFC-141b blowing agents and handle accordingly
Older foam insulation often contains HCFC-141b, a regulated ozone-depleting substance, and must be treated as such until confirmed otherwise.
Question 5: Which document must accompany a shipment of used oils collected from appliances during the recycling process?
- Material Safety Data Sheet only
- A uniform hazardous waste manifest if the oil is a listed hazardous waste (Correct answer)
- A bill of lading with no additional documentation
- An EPA Form 8700-12 generator notification
Correct answer: A uniform hazardous waste manifest if the oil is a listed hazardous waste
Used oil that meets the criteria of a hazardous waste requires a uniform hazardous waste manifest when transported off-site.
Question 6: What is the significance of the 'de minimis' exemption under RCRA for appliance recyclers?
- It exempts recyclers from all hazardous waste regulations
- It allows very small quantities of hazardous material releases during normal operations to be excluded (Correct answer)
- It permits unlimited venting of refrigerants at no penalty
- It classifies all appliance parts as universal waste
Correct answer: It allows very small quantities of hazardous material releases during normal operations to be excluded
The de minimis exemption covers incidental, unavoidable trace releases that occur during normal recycling operations and would not constitute a regulatory violation.
Question 7: Under EPA's Universal Waste Rule, which of the following appliance components can typically be managed as universal waste?
- Compressor oils
- Mercury thermostats and mercury switches (Correct answer)
- CFC refrigerants
- PCB capacitors
Correct answer: Mercury thermostats and mercury switches
Mercury-containing devices such as thermostats and switches qualify as universal waste under 40 CFR Part 273, simplifying their handling and disposal requirements.
