Under the EPA's derived-from rule, residues from hazardous waste incineration are regulated as hazardous waste. Which statement is correct?

• A. They remain hazardous waste because of the derived-from rule
• B. They are automatically exempt from regulation
• C. They are only hazardous if listed
• D. They become nonhazardous if incinerated

Answer: (A)

Under the EPA’s derived-from rule, residues from hazardous waste incineration stay hazardous waste because they come from a hazardous waste in the first place. The rule treats any waste derived from a hazardous waste as hazardous itself, so ash or other byproducts produced during incineration must be managed as hazardous waste. This prevents shifting hazardous material into less-regulated streams and ensures proper handling, treatment, and disposal. The residues aren’t automatically exempt, aren’t only hazardous if listed, and aren’t rendered nonhazardous simply by being incinerated.
