What this exam covers
5 real sample questions
A Large Quantity Generator (LQG) is generally a facility that generates in a calendar month:
A. Less than 100 kg of hazardous waste
B. 1,000 kg (2,200 lbs) or more of hazardous waste, or more than 1 kg of acutely hazardous waste
C. Exactly 50 kg every month with no exceptions
D. Only non-hazardous universal waste
Show answer and reasoning

Correct answer: B. 1,000 kg (2,200 lbs) or more of hazardous waste, or more than 1 kg of acutely hazardous waste

Correct. 40 CFR 262.13 sets the LQG threshold at 1,000 kg/month or more of hazardous waste (or more than 1 kg/month of acutely hazardous waste).

  • A: Less than 100 kg per month is within the VSQG range, not LQG.
  • C: The regulatory thresholds are quantity ranges, not one single fixed exact monthly figure.
  • D: Universal waste is regulated under a separate, streamlined system (40 CFR Part 273), not the LQG hazardous waste threshold.
Source: 40 CFR 262.13(b)
A Small Quantity Generator (SQG) generally generates between:
A. 100 kg and 1,000 kg of hazardous waste per calendar month
B. 0 and 1 kg per month only
C. 10,000 kg and 50,000 kg per month
D. There is no defined SQG range
Show answer and reasoning

Correct answer: A. 100 kg and 1,000 kg of hazardous waste per calendar month

Correct. 40 CFR 262.13 defines the SQG range as generating between 100 kg and 1,000 kg of hazardous waste per calendar month (and no more than 1 kg of acutely hazardous waste).

  • B: That extremely small range corresponds to VSQG territory, not SQG.
  • C: That very high range would place a facility well above the LQG threshold.
  • D: A specific defined quantity range is set for SQG status.
Source: 40 CFR 262.13(a)
A Very Small Quantity Generator (VSQG) generally generates:
A. 100 kg or more per month
B. Less than or equal to 100 kg of hazardous waste per calendar month (and no more than 1 kg of acutely hazardous waste)
C. Exactly 1,000 kg per month
D. There is no VSQG category under current regulations
Show answer and reasoning

Correct answer: B. Less than or equal to 100 kg of hazardous waste per calendar month (and no more than 1 kg of acutely hazardous waste)

Correct. 40 CFR 262.13 sets the VSQG threshold at generating 100 kg or less of hazardous waste per month (with a lower limit for acutely hazardous waste).

  • A: 100 kg or more moves a facility out of VSQG status into SQG or higher.
  • C: 1,000 kg per month is the LQG threshold, not VSQG.
  • D: VSQG remains a recognized, currently defined generator category under 40 CFR 262.13/262.14.
Source: 40 CFR 262.13
A Large Quantity Generator (LQG) may generally accumulate hazardous waste on site without a permit for up to:
A. 90 days, subject to specified conditions
B. 10 years
C. There is no time limit for LQGs
D. Only 12 hours
Show answer and reasoning

Correct answer: A. 90 days, subject to specified conditions

Correct. 40 CFR 262.17 allows LQGs to accumulate hazardous waste on site for up to 90 days without a storage permit, provided applicable container, tank, and other standards are met.

  • B: 10 years is far beyond any permitted LQG accumulation window.
  • C: A specific, shorter time limit (90 days) applies to LQGs, unlike this option's claim of no limit.
  • D: 12 hours understates the actual regulatory accumulation window for LQGs.
Source: 40 CFR 262.17
Universal waste handlers must generally accumulate universal waste for no longer than:
A. 1 year from the date it becomes a universal waste (or is generated), absent an approved extension
B. 10 years
C. There is no accumulation time limit for universal waste
D. 24 hours
Show answer and reasoning

Correct answer: A. 1 year from the date it becomes a universal waste (or is generated), absent an approved extension

Correct. 40 CFR 273.13 (small quantity handlers) and 273.14 (large quantity handlers) generally cap universal waste accumulation at 1 year, with limited extension provisions in specific circumstances.

  • B: 10 years far exceeds the standard universal waste accumulation time limit.
  • C: A defined accumulation time limit does apply to universal waste, unlike full exemption from any time constraint.
  • D: 24 hours is far shorter than the actual regulatory accumulation time limit for universal waste.
