Nessel also filed a separate court action to dismiss Enbridge's June 6 suit. "The company has asked that court to uphold a series of agreements made last year with Gov. Rick Snyder—Whitmer's Republican predecessor—to replace the Straits pipelines and bury new lines in a bedrock tunnel expected to cost Enbridge US$500 million," Bridge Michigan notes. "Enbridge disputes that it was unwilling to negotiate with Whitmer and said her administration's insistence on shutting down the current pipeline in two years was a non-starter. Enbridge last month said it could finish a Line 5 tunnel by 2024 at the earliest, shaving years off its previous timeline."
