Comment submitted by Association of Metropolitan Water Agencies (AMWA)

Summary: The Association of Metropolitan Water Agencies (AMWA) opposes the proposed revisions because they shift costs and risks from power plants to drinking water systems by replacing national numerical limits with state-by-state best professional judgment. The organization argues that the EPA should strengthen the rule to explicitly protect drinking water sources and complete a cost-benefit analysis that monetizes the public health and treatment costs shifted to ratepayers.
