Tennessee Clean Water Network v. Tennessee Valley Authority   (6th Circuit)

Conduit theory of liability for pollutants

The NAM filed an amicus brief in the U.S. Court of Appeals for the Sixth Circuit to oppose lawsuits by environmental plaintiff groups that sought to massively expand manufacturers’ liability under the Clean Water Act. In a lawsuit against electric generation facilities, the plaintiffs argued that federal jurisdiction applies to all groundwater throughout the United States (in addition to certain categories of surface waters). If that theory of jurisdiction prevails, manufacturers could be subject to massive and unpredictable liability for any impacts their operations may have on groundwater. The NAM’s amicus brief argued against this overbroad theory of liability. The Sixth Circuit ruled against the plaintiffs and in favor of manufacturers by rejecting the plaintiffs’ claims and holding that the Clean Water Act does not apply to discharges to groundwater.
