What this exam covers
5 real sample questions
A waste solution has a pH of 1.2 and corrodes steel. What hazard characteristic applies?
A. Toxicity
B. Correct. Corrosivity is defined by pH below 2 or ability to corrode steel.
C. Reactivity
D. Ignitability
Show answer and reasoning

Correct answer: A. Toxicity

Toxicity is measured via leaching tests; low pH alone does not establish toxicity.

  • B: Correct. Corrosivity is defined by pH below 2 or the ability to corrode steel.
  • C: Reactivity involves violent reactions with water or air, not pH alone.
  • D: Corrosive liquids are not inherently ignitable.
Source: 40 CFR 261.22
A manufacturing facility generates 95 kilograms of hazardous waste per calendar month. How is this generator classified under RCRA?
A. Very Small Quantity Generator (VSQG)
B. Small Quantity Generator (SQG)
C. Large Quantity Generator (LQG)
D. Conditionally Exempt Small Quantity Generator (CESQG)
Show answer and reasoning

Correct answer: D. Conditionally Exempt Small Quantity Generator (CESQG)

CESQG applies to certain waste streams; classification by mass is VSQG.

  • A: Correct. VSQG threshold is below 100 kg/month; 95 kg falls within this category.
  • B: SQG threshold is 100 kg/month minimum; this facility falls below.
  • C: LQG threshold is 1,000 kg/month minimum; this facility generates far less.
Source: 40 CFR 262.41
A printing operation generates 150 kilograms of hazardous waste monthly. Which category applies?
A. Exempt from RCRA reporting
B. Large Quantity Generator (LQG)
C. Correct. SQG applies to generators producing 100-1000 kg/month.
D. Very Small Quantity Generator (VSQG)
Show answer and reasoning

Correct answer: A. Exempt from RCRA reporting

No generator quantity falls outside RCRA requirements.

  • B: LQG threshold is 1,000 kg/month; 150 kg is below this.
  • C: Correct. SQG applies to generators producing 100-1000 kg/month.
  • D: VSQG limit is below 100 kg/month; this facility exceeds that threshold.
Source: 40 CFR 262.41
A facility must determine if a solid waste is hazardous by evaluating which characteristics?
A. Weight, volume, source, and density
B. Appearance, cost, disposal method, and age
C. Correct. Ignitability, corrosivity, reactivity, and toxicity define hazardous waste.
D. Color, odor, texture, and phase
Show answer and reasoning

Correct answer: A. Weight, volume, source, and density

Quantity metrics do not define hazard.

  • B: Economic or logistical attributes do not determine hazard classification.
  • C: Physical properties like color and odor are descriptive but not regulatory hazard characteristics.
  • D: Correct. These four characteristics define hazardous waste under 40 CFR 261.
Source: 40 CFR 261.3
Which of the following best defines an ignitable hazardous waste?
A. Any waste that has ever been exposed to heat or flame
B. Waste that contains any amount of combustible material
C. Waste that darkens or discolors when exposed to air
D. Correct. A liquid with a flash point below 140°F or a solid that burns.
Show answer and reasoning

Correct answer: D. Correct. A liquid with a flash point below 140°F or a solid that burns.

Presence of combustible material alone is insufficient; flash point thresholds apply.

  • A: Prior exposure to heat does not define ignitability under EPA testing.
  • B: Correct. Ignitability is defined by specific flash point thresholds under 40 CFR 261.21.
  • C: Color change is not a regulatory ignitability criterion.
