Comment submitted by American Water Works Association (AWWA)

Summary: The American Water Works Association (AWWA) supports the EPA's proposal to provide a federal exemptions framework and additional time for water systems to comply with PFOA and PFOS maximum contaminant levels. They argue that the current compliance timeline is insufficient due to high capital costs and complex infrastructure needs, and they urge the EPA to finalize the rule quickly and expand it to include Hazard Index (HI) PFAS.
