The criteria restricting land spreading of wastes with high cadmium and PCBs to protect groundwater are found in which subpart?

• A. Subpart A
• B. Subpart J
• C. Subpart D
• D. Subpart C

Answer: (A)

The main idea here is where broad groundwater protection standards are set for land spreading of wastes. Those general provisions establish the baseline rules for how wastes can be spread on land and when tighter controls are needed to prevent groundwater contamination. Cadmium and PCBs are hazardous constituents that trigger stricter requirements, so the criteria governing their land-spreading practices are placed in the general, overarching subpart. The other subparts tend to address more specific topics or particular waste streams, not the broad groundwater-protection standards, which is why this is the most fitting location.
