Lawsuit Against Line 5 Screw Anchor Supports Dismissed

The Straits of Mackinac Alliance, Grand Traverse Band of Ottawa and Chippewa Indians and the City of Mackinac Island have agreed to dismiss their case against the Michigan Department of Environment, Great Lakes, and Energy (EGLE) challenging Enbridge’s ability to install screw anchors on its Line 5 dual pipelines in the Straits of Mackinac. The anchors are a critical part of Enbridge’s ongoing Line 5 safety and maintenance program.

The groups’ decision to dismiss their case follows a ruling by an administrative law judge in February in which the judge dismissed most of their claims. The groups’ challenge had sought to invalidate EGLE’s decision to issue permits authorizing the installation of additional anchors that physically secure Line 5 to the lakebed. 

Since 2002, Enbridge has installed 181 supports on Line 5 and plans to install an additional 20 supports this year. The supports and Enbridge’s other maintenance and safety measures ensure the Straits are protected and energy keeps flowing to those who depend on it every day.
