Under Wisconsin's hazardous waste generator framework (mirroring federal RCRA generator categories), a facility that generates 220 pounds (100 kg) or less of non-acute hazardous waste per month, and accumulates no more than 2,205 pounds (1,000 kg) at any time, is classified as a:
A. Large Quantity Generator (LQG)
B. Small Quantity Generator (SQG)
C. Very Small Quantity Generator (VSQG)
D. Exempt generator with no regulatory category
Show answer and reasoning
Correct answer: C. Very Small Quantity Generator (VSQG)
Correct. A facility generating 220 pounds (100 kg) or less of non-acute hazardous waste per month, and accumulating no more than 2,205 pounds (1,000 kg) at any time, meets the Very Small Quantity Generator (VSQG) threshold under Wisconsin's generator category framework.
- A: Incorrect. LQGs generate 2,205 pounds (1,000 kg) or more of non-acute hazardous waste per month, far more than the described facility.
- B: Incorrect. SQGs generate between 220 and 2,205 pounds of non-acute hazardous waste per month, exceeding the described facility's generation level.
- D: Incorrect. VSQGs remain a defined, regulated generator category with specific management requirements; they are not entirely exempt from all regulation.

Wisconsin's hazardous waste management program, administered by the DNR, implements federal RCRA Subtitle C requirements through which Wisconsin Administrative Code chapter series?
A. ATCP 75
B. The NR 600 series (e.g., NR 662 generator standards)
C. Ins 6
D. DSPS 130
Show answer and reasoning
Correct answer: B. The NR 600 series (e.g., NR 662 generator standards)
Correct. Wisconsin implements its federally authorized hazardous waste program, including generator requirements, through the NR 600 series of the Wisconsin Administrative Code (with generator category standards specifically addressed in chapters such as NR 662), administered by the DNR.
- A: Incorrect. ATCP 75 governs Wisconsin's retail food code, unrelated to hazardous waste management.
- C: Incorrect. Ins 6 is an OCI insurance administrative code chapter, unrelated to hazardous waste regulation.
- D: Incorrect. DSPS 130 relates to a professional licensing chapter administered by DSPS, not DNR's hazardous waste program.

A facility generating between 220 and 2,205 pounds of non-acute hazardous waste per calendar month is classified as which generator category?
A. Very Small Quantity Generator (VSQG)
B. Small Quantity Generator (SQG)
C. Large Quantity Generator (LQG)
D. Conditionally Exempt Generator only, with no other classification available
Show answer and reasoning
Correct answer: B. Small Quantity Generator (SQG)
Correct. A Small Quantity Generator (SQG) is defined as generating between 220 pounds and 2,205 pounds of non-acute hazardous waste per calendar month, with additional and more stringent management requirements than a VSQG.
- A: Incorrect. VSQGs generate 220 pounds or less per month, below the range described in this scenario.
- C: Incorrect. LQGs generate 2,205 pounds or more of non-acute hazardous waste per month, above the range described in this scenario.
- D: Incorrect. 'Conditionally exempt generator' is an older/informal term roughly analogous to today's VSQG category, not the classification for a facility generating in the 220-2,205 pound range, which is properly classified as an SQG.

A facility that generates 2,205 pounds (1,000 kg) or more of non-acute hazardous waste in a calendar month is classified as a:
A. Very Small Quantity Generator (VSQG)
B. Small Quantity Generator (SQG)
C. Large Quantity Generator (LQG)
D. There is no generator category at this generation level
Show answer and reasoning
Correct answer: C. Large Quantity Generator (LQG)
Correct. A facility generating 2,205 pounds (1,000 kg) or more of non-acute hazardous waste per calendar month is classified as a Large Quantity Generator (LQG), subject to the most stringent generator management standards.
- A: Incorrect. VSQGs generate far less waste (220 pounds or less per month); this generation level far exceeds the VSQG threshold.
- B: Incorrect. SQGs generate between 220 and 2,205 pounds per month; a facility at or above 2,205 pounds per month exceeds the SQG range.
- D: Incorrect. This generation level is specifically and clearly classified as LQG; it is not an unregulated or uncategorized level of generation.

For acute hazardous waste (such as certain P-listed wastes), the quantity threshold that would push a generator above VSQG status is dramatically lower than for non-acute hazardous waste. What is the generally recognized threshold for acute hazardous waste generation that maintains VSQG-eligible status?
A. 2.2 pounds (1 kg) or less per calendar month
B. 220 pounds (100 kg) or less per calendar month, the same as non-acute waste
C. 2,205 pounds (1,000 kg) or less per calendar month
D. There is no separate threshold for acute hazardous waste
Show answer and reasoning
Correct answer: A. 2.2 pounds (1 kg) or less per calendar month
Correct. Acute hazardous waste has a much lower generation threshold: generating 2.2 pounds (1 kg) or less per calendar month (and accumulating no more than 2.2 pounds/1 kg at any time) is required to remain within VSQG status for that acute waste stream, reflecting the significantly higher hazard associated with acute hazardous wastes.
- B: Incorrect. The 220-pound threshold applies to NON-acute hazardous waste; acute hazardous waste is subject to a much stricter, lower threshold given its higher toxicity/hazard level.
- C: Incorrect. 2,205 pounds is the LQG threshold for non-acute waste; it is far too high and does not reflect the appropriately stricter acute hazardous waste threshold.
- D: Incorrect. Acute hazardous waste is specifically subject to a distinct, much lower quantity threshold than non-acute hazardous waste under the generator category framework.
