What this exam covers
5 real sample questions
A waste is generally considered 'corrosive' under RCRA if it is aqueous and has a pH:
A. Between 6 and 8
B. Less than or equal to 2, or greater than or equal to 12.5
C. Exactly 7.0
D. Above 14
Show answer and reasoning

Correct answer: B. Less than or equal to 2, or greater than or equal to 12.5

Correct. 40 CFR § 261.22 defines corrosivity in part as an aqueous waste with a pH less than or equal to 2 or greater than or equal to 12.5.

  • A: A pH between 6 and 8 is roughly neutral and does not meet the corrosivity characteristic threshold.
  • C: A pH of exactly 7.0 is neutral, well outside the corrosivity range.
  • D: pH is measured on a 0-14 scale; a value 'above 14' is not a standard measurement and does not describe the regulatory threshold correctly.
Source: 40 CFR § 261.22
The Toxicity Characteristic (TC) is determined using which specific analytical test method?
A. Flash point testing
B. Toxicity Characteristic Leaching Procedure (TCLP)
C. pH paper strip testing only
D. Visual inspection alone
Show answer and reasoning

Correct answer: B. Toxicity Characteristic Leaching Procedure (TCLP)

Correct. 40 CFR § 261.24 specifies the TCLP test method to determine whether a waste exhibits the toxicity characteristic based on regulated constituent leachate concentrations.

  • A: Flash point testing determines ignitability, not the toxicity characteristic.
  • C: Basic pH testing alone does not determine the toxicity characteristic; TCLP specifically evaluates leachable toxic constituents.
  • D: Visual inspection cannot determine chemical toxicity characteristics; laboratory testing (TCLP) is required.
Source: 40 CFR § 261.24
An LQG may generally accumulate hazardous waste on-site without a permit for up to how long?
A. 90 days
B. 180 days
C. 1 year with no conditions
D. There is no time limit for LQGs
Show answer and reasoning

Correct answer: A. 90 days

Correct. 40 CFR § 262.17 generally limits LQG on-site accumulation without a permit to 90 days.

  • B: 180 days is the SQG standard limit, not the LQG limit.
  • C: LQGs are subject to a defined, shorter accumulation time limit than a full year with no conditions.
  • D: LQGs are subject to the 90-day accumulation time limit under the generator improvements rule, among other requirements.
Source: 40 CFR § 262.17
Under RCRA, who is responsible for determining whether a solid waste generated at a facility is a hazardous waste?
A. The waste hauler
B. The generator of the waste
C. The disposal facility only, after the waste arrives
D. EPA, on a case-by-case basis for every facility
Show answer and reasoning

Correct answer: B. The generator of the waste

Correct. 40 CFR § 262.11 places the burden on the generator to determine at the point of generation whether a solid waste is a hazardous waste.

  • A: The hauler transports waste but is not the party responsible for the initial hazardous waste determination.
  • C: Waiting until the waste reaches a disposal facility would be too late; the determination must be made at the point of generation.
  • D: EPA does not make individual determinations for every generator; the regulatory duty is on the generator itself.
Source: 40 CFR § 262.11
A waste is considered a 'hazardous waste' under RCRA if it is first a 'solid waste' and then meets which additional condition?
A. It is stored in a metal container
B. It exhibits a characteristic of hazardous waste (ignitability, corrosivity, reactivity, or toxicity) or is specifically listed as a hazardous waste
C. It was generated more than 90 days ago
D. It has a market value
Show answer and reasoning

Correct answer: B. It exhibits a characteristic of hazardous waste (ignitability, corrosivity, reactivity, or toxicity) or is specifically listed as a hazardous waste

Correct. Under 40 CFR § 261.3, a solid waste is a hazardous waste if it exhibits one or more characteristics defined in Subpart C or is specifically listed in Subpart D.

  • A: Container material is unrelated to the regulatory hazardous waste determination.
  • C: Storage duration relates to accumulation time limits, not the initial hazardous waste determination.
  • D: Market value/reusability does not itself determine hazardous waste status under this framework.
