Which statement correctly contrasts U/P wastes with F/K wastes?

• A. U- and P-listed wastes are virgin wastes; F-listed wastes originate from non-specific sources; K-listed wastes originate from specific industries.
• B. F-listed wastes originate from non-specific sources; U- and P-listed wastes are virgin wastes; K-listed wastes originate from specific industries.
• C. K-listed wastes originate from non-specific sources.
• D. All listed wastes are virgin wastes.

Answer: (A)

U and P wastes come from discarded commercial chemical products—the product itself is treated as the waste. Because these wastes are the chemical products originally manufactured and now being discarded, they’re described as “virgin” wastes in regulatory language. In contrast, F-listed wastes come from non-specific sources and K-listed wastes come from specific industries or processes. This aligns with the statement that U/P wastes are virgin wastes, F-listed wastes originate from non-specific sources, and K-listed wastes originate from specific industries.
