CHMM Waste Management 2 — Questions and Answers
Question 1: Under RCRA, which of the following actions qualifies as 'treatment' of hazardous waste?
- Storing waste in a 90-day accumulation area
- Neutralizing acidic waste to change its pH (Correct answer)
- Transporting waste to an off-site facility
- Completing a hazardous waste manifest
Correct answer: Neutralizing acidic waste to change its pH
RCRA defines treatment as any method, technique, or process designed to change the physical, chemical, or biological character of hazardous waste, such as neutralization.
Question 2: A generator produces exactly 99 kg of acute hazardous waste in a calendar month. How is this generator classified?
- Very Small Quantity Generator (VSQG)
- Small Quantity Generator (SQG)
- Large Quantity Generator (LQG) (Correct answer)
- Conditionally Exempt Small Quantity Generator (CESQG)
Correct answer: Large Quantity Generator (LQG)
Generators producing more than 1 kg of acute (P-listed) hazardous waste per month are classified as Large Quantity Generators regardless of total waste volume.
Question 3: Which document must accompany a hazardous waste shipment from the point of generation to its final destination?
- Bill of lading
- Uniform Hazardous Waste Manifest (Correct answer)
- EPA Notification Form
- OSHA 300 Log
Correct answer: Uniform Hazardous Waste Manifest
The Uniform Hazardous Waste Manifest (EPA Form 8700-22) must accompany all off-site shipments of hazardous waste.
Question 4: Which waste code category covers wastes from specific industries such as petroleum refining and wood preserving?
- F-listed wastes
- K-listed wastes (Correct answer)
- P-listed wastes
- U-listed wastes
Correct answer: K-listed wastes
K-listed wastes are source-specific hazardous wastes generated by specific industrial processes such as petroleum refining, wood preserving, and inorganic chemical production.
Question 5: Under RCRA land disposal restrictions (LDRs), what must a generator provide when shipping restricted hazardous waste off-site?
- A closure plan
- A land disposal restriction notification (Correct answer)
- A contingency plan
- A hazardous waste permit
Correct answer: A land disposal restriction notification
Generators must provide LDR notification (treatment standards documentation) with each shipment of restricted hazardous waste sent for disposal.
Question 6: What is the maximum allowable accumulation time for hazardous waste at a Large Quantity Generator facility without a storage permit?
- 90 days (Correct answer)
- 180 days
- 270 days
- 365 days
Correct answer: 90 days
Large Quantity Generators may accumulate hazardous waste on-site for up to 90 days without a storage permit under RCRA regulations.
Question 7: Which RCRA corrective action program addresses releases of hazardous waste or constituents at permitted TSD facilities?
- Superfund CERCLA cleanup
- RCRA Section 3004(u) corrective action (Correct answer)
- OSHA PSM standard
- Clean Water Act NPDES program
