Which statement about the federal regulation of household hazardous waste (HHW) is accurate?

• A. HHW is regulated the same as other hazardous wastes under Subtitle C.
• B. HHW is regulated only at the state level.
• C. HHW is generally exempt from standard hazardous waste regulations, though states may regulate it.
• D. HHW requires a Part B permit to manage.

Answer: (C)

The idea being tested is how household hazardous waste fits into the federal RCRA framework. Federal hazardous waste rules under Subtitle C are designed primarily for waste from industrial and commercial sources, not households. Because household hazardous waste is generated by residents, it is generally exempt from those federal hazardous waste requirements. States, however, may regulate HHW under their own programs, so management can vary by state. This is why the statement that HHW is generally exempt from standard hazardous waste regulations, though states may regulate it, is the best description. A statement that HHW is regulated the same as other hazardous wastes under Subtitle C isn’t correct, because Subtitle C rules target non-household sources and users, not typical household waste. Saying it’s regulated only at the state level isn’t precise either, since states may regulate HHW, but the federal framework does not treat household waste as hazardous waste the same way it treats industrial hazardous waste. The idea that HHW requires a Part B permit isn’t accurate for the same reason—the Part B permitting regime applies to facilities managing federally regulated hazardous waste, which HHW generally isn’t under Subtitle C.
