The full list of wastes found on both the P-List and U-List can be found under 40 CFR ______

• A. §261.31
• B. §261.33
• C. §261.32
• D. §262.33

Answer: (B)

The P-list and U-list are two separate hazardous-waste listings under RCRA: the P-list covers acutely hazardous wastes, and the U-list covers discarded commercial chemical products. The full compilation of wastes that appear on either list is found in 40 CFR §261.33, which serves as the consolidated reference for wastes on both lists. The other sections are the individual lists themselves (P-list or U-list) and do not provide the combined roster. Therefore, 40 CFR §261.33 is the correct place to look for the complete set of wastes on both lists.
