Which activities are regulated for PCBs?

• A. Gardening and farming only
• B. Industrial manufacturing only
• C. Use, storage, transport, disposal
• D. Cooking and cleaning with PCB-containing substances

Answer: (D)

PCBs are regulated throughout their entire life cycle to prevent release and exposure. The activities that regulators focus on are how PCBs are used, stored, transported, and disposed. Each stage has safeguards to keep PCB-containing materials contained, prevent environmental release, and ensure safe handling.

Explain why this scope fits regulation better than the other options: gardening or farming isn’t a primary regulatory category for PCB management, industrial manufacturing alone is too narrow to cover how PCBs are actually used and handled in the field, and cooking or cleaning with PCB-containing substances would be a specific exposure scenario rather than the overarching set of activities that rules govern. The regulated framework is about use, storage, transport, and disposal, reflecting the full pathway from how PCBs are managed during operation to how they are finally disposed of.
