Which statement best describes each waste type?

• A. F-listed wastes are generated by non-specific sources; K-listed wastes are generated by specific industries; U- and P-listed wastes are virgin wastes.
• B. U- and P-listed wastes are non-virgin wastes.
• C. F-listed wastes originate from specific industries.
• D. K-listed wastes originate from household waste streams.

Answer: (A)

Understanding how RCRA lists classify hazardous wastes helps you see why this statement fits. F-listed wastes come from non-specific sources—these are wastes from common industrial activities that aren’t tied to a single process or industry. K-listed wastes come from specific industries or processes, meaning they’re generated by particular sectors. U-listed and P-listed wastes are discarded commercial chemical products; they’re regulatory wastes that result when unused or off-spec products are thrown away, which is why they’re described as “virgin” wastes in this context. So the description that F-listed wastes come from non-specific sources, K-listed from specific industries, and U- and P-listed wastes are discarded commercial chemical products (virgin wastes) matches how the lists are defined. The other statements mischaracterize where F-, K-, and U/P-listed wastes originate.
