Which of the following is an example of a hazardous waste under RCRA Subtitle C?

• A. Household garbage
• B. Paper waste
• C. Solid non-hazardous waste
• D. Used solvents and other hazardous wastes generated by a facility

Answer: (D)

Hazardous waste under RCRA Subtitle C is waste that either appears on one of the federal hazard lists or shows one of four dangerous characteristics: ignitable, corrosive, reactive, or toxic. Used solvents and other hazardous wastes generated by a facility fit this definition because solvents are a common example of ignitable or toxic waste and may also appear on the listed waste tables. Household garbage and paper waste are typically not hazardous unless contaminated with hazardous materials, and solid non-hazardous waste is, by definition, not hazardous. So the example that clearly meets the hazardous-waste criteria is the used solvents and other hazardous wastes generated by a facility.
