Comment submitted by Keweenaw Bay Indian Community Lake Superior Band of Chippewa Indians

Summary: The Keweenaw Bay Indian Community, a federally recognized Tribal Nation, opposes the proposed rule to extend the compliance deadline for PFOA and PFOS maximum contaminant levels. They argue that the extension is an unlawful administrative evasion of statutory limits and that the proposed health risk thresholds are scientifically unsupported and inadequate for protecting public health.
