What this exam covers
5 real sample questions
Under the RCRA Generator Improvements Rule, a facility that generates 100 kilograms or less of hazardous waste per month (and 1 kg or less of acute hazardous waste) is classified as which generator category?
A. Very Small Quantity Generator (VSQG)
B. Small Quantity Generator (SQG)
C. Large Quantity Generator (LQG)
D. Conditionally Non-Regulated Generator
Show answer and reasoning

Correct answer: A. Very Small Quantity Generator (VSQG)

Correct. 40 CFR 262.13 defines a VSQG as generating 100 kg/month or less of hazardous waste and 1 kg/month or less of acute hazardous waste.

  • B: SQGs generate more than 100 kg but less than 1,000 kg per month, a higher threshold than described.
  • C: LQGs generate 1,000 kg/month or more, far above the threshold in the question.
  • D: This is not a defined RCRA generator category; VSQG is the correct term used in the regulation.
Source: 40 CFR 262.13
A Colorado facility generates 450 kg of hazardous waste in a calendar month and no acute hazardous waste. Under 40 CFR 262.13, how is this facility classified for that month?
A. Large Quantity Generator (LQG)
B. Small Quantity Generator (SQG)
C. Very Small Quantity Generator (VSQG)
D. Exempt generator
Show answer and reasoning

Correct answer: B. Small Quantity Generator (SQG)

Correct. SQGs generate more than 100 kg but less than 1,000 kg of hazardous waste per calendar month, which fits 450 kg.

  • A: LQG status requires generating 1,000 kg/month or more; 450 kg does not meet this threshold.
  • C: VSQG status caps at 100 kg/month; 450 kg exceeds that threshold.
  • D: RCRA does not provide a blanket exemption at this quantity; the facility is regulated as an SQG.
Source: 40 CFR 262.13
Under federal RCRA regulations applicable in Colorado, how long may a Large Quantity Generator (LQG) accumulate hazardous waste on-site without a storage permit, absent an approved extension?
A. 90 days
B. 180 days
C. 270 days
D. One year
Show answer and reasoning

Correct answer: A. 90 days

Correct. 40 CFR 262.17 sets the LQG on-site accumulation time limit at 90 days without a permit.

  • B: 180 days is the standard SQG accumulation limit, not the LQG limit.
  • C: 270 days applies to SQGs shipping waste more than 200 miles to a designated facility, not to LQGs.
  • D: RCRA does not permit indefinite or one-year unpermitted accumulation for LQGs without a permit.
Source: 40 CFR 262.17
A Colorado Small Quantity Generator (SQG) ships its hazardous waste to a designated facility located more than 200 miles away. What is the maximum on-site accumulation time allowed without a permit?
A. 90 days
B. 180 days
C. 270 days
D. 365 days
Show answer and reasoning

Correct answer: C. 270 days

Correct. 40 CFR 262.16 extends the SQG accumulation limit to 270 days when the waste must travel more than 200 miles to its designated facility.

  • A: 90 days is the LQG accumulation limit, not the extended SQG limit for long-distance shipments.
  • B: 180 days is the standard SQG accumulation limit when shipping distance is not a factor.
  • D: 365 days exceeds any RCRA generator accumulation time limit without a permit.
Source: 40 CFR 262.16
Under the satellite accumulation area provisions at 40 CFR 262.15, hazardous waste may accumulate at or near the point of generation, under the control of the operator, without triggering the standard accumulation time limit, provided the container holds no more than how much hazardous waste (or 1 quart of acute hazardous waste)?
A. 55 gallons
B. 110 gallons
C. 10 gallons
D. 220 gallons
Show answer and reasoning

Correct answer: A. 55 gallons

Correct. 40 CFR 262.15 caps satellite accumulation at 55 gallons of hazardous waste (or 1 quart of acute hazardous waste) per satellite area before the clock for moving/managing the waste starts.

  • B: 110 gallons is not the satellite accumulation cap under 262.15.
  • C: 10 gallons is not the regulatory threshold; 55 gallons is the correct figure.
  • D: 220 gallons is not the regulatory threshold; 55 gallons is the correct figure.
