What this exam covers
5 real sample questions
Which Part 273 subpart contains the LQHUW standards, running from applicability through exports?
A. Subpart A
B. Subpart B
C. Subpart C
D. Subpart D
Show answer and reasoning

Correct answer: C. Subpart C

  • A: Subpart A contains general provisions and definitions (273.1-273.9), not the LQHUW operating standards.
  • B: Subpart B contains the SQHUW standards.
  • D: Subpart D contains the universal waste transporter standards.
Source: 40 CFR 273.30
Which section of 40 CFR Part 273 establishes the applicability of the Large Quantity Handler of Universal Waste standards?
A. 40 CFR 273.10
B. 40 CFR 273.20
C. 40 CFR 273.30
D. 40 CFR 273.50
Show answer and reasoning

Correct answer: C. 40 CFR 273.30

  • A: 273.10 is the SQHUW applicability section under Subpart B.
  • B: 273.20 covers exports under Subpart B, not LQHUW applicability.
  • D: 273.50 is the transporter applicability section under Subpart D.
Source: 40 CFR 273.30
A homeowner discards used household batteries and a broken mercury thermometer in household trash. Which section addresses why this is generally not subject to Part 273 handler obligations?
A. 40 CFR 273.1
B. 40 CFR 273.8
C. 40 CFR 273.60
D. 40 CFR 273.20
Show answer and reasoning

Correct answer: B. 40 CFR 273.8

  • A: 273.1 is the general scope/purpose statement, not the household-waste applicability provision.
  • C: 273.60 addresses destination facility applicability, unrelated to household waste status.
  • D: 273.20 addresses SQHUW exports, unrelated to household waste status.
Source: 40 CFR 273.8
Under 40 CFR 273.9, what aggregate quantity of universal waste accumulated at any time makes a handler a Large Quantity Handler of Universal Waste (LQHUW)?
A. 1,000 kg or more
B. 2,200 kg or more
C. 5,000 kg or more
D. 6,000 kg or more
Show answer and reasoning

Correct answer: C. 5,000 kg or more

  • A: 1,000 kg is the RCRA hazardous waste "acute hazardous waste" generator threshold, not the universal waste LQHUW threshold.
  • B: 2,200 kg (about 2.2 tons) is not a threshold used anywhere in Part 273.
  • D: 6,000 kg overstates the real 273.9 threshold of 5,000 kg.
Source: 40 CFR 273.9
The 5,000 kg LQHUW threshold in 40 CFR 273.9 is calculated how?
A. Separately for each of the five universal waste categories
B. Collectively across all universal waste categories the handler accumulates (batteries, pesticides, mercury-containing equipment, lamps, and aerosol cans combined)
C. Only counting universal waste batteries, since batteries are usually the heaviest waste stream
D. As an annual generation total rather than an at-any-time accumulation total
Show answer and reasoning

Correct answer: B. Collectively across all universal waste categories the handler accumulates (batteries, pesticides, mercury-containing equipment, lamps, and aerosol cans combined)

  • A: The regulation aggregates across categories; a handler with 3,000 kg of batteries and 2,500 kg of lamps is an LQHUW even though no single category reaches 5,000 kg.
  • C: Batteries are not singled out; all five streams count toward the same combined total.
  • D: It is explicitly an "at any time" accumulated-quantity test, not an annual generation total.
