- CThe P-list
- DThe U-list
Solution
Concept
US EPA hazardous waste lists (RCRA)
Step-by-step solution
1. F-list: wastes from non-specific sources (common manufacturing and industrial processes, e.g. spent solvents). 2. K-list: wastes from specific industries. 3. P- and U-lists: discarded commercial chemical products.
Explanation
The F-list covers hazardous wastes from common industrial operations such as degreasing solvents.
Why the other options are wrong
K-list is for specific industry sources, and P and U lists are for unused commercial chemical products.
Shortcut
F = Frequent/common sources; K = specific; P, U = chemicals.
Common mistake
Choosing the K-list.
Correct answer: A) The F-list
