Comment submitted by Illinois Environmental Regulatory Group (IERG) and Illinois Manufacturing Association (IMA)

Summary: The Illinois Environmental Regulatory Group (IERG) and the Illinois Manufacturers’ Association (IMA) express concern that the "pharmaceuticals" category in the draft CCL 6 is too broad and lacks the structured framework used for other contaminant groups. They argue that the current definition covers too many diverse compounds and request that the EPA provide more specific prioritization, subgrouping, and risk-based screening criteria to ensure resources are focused on the most relevant contaminants.
