MI SR0056

Urges the Governor and Attorney General to immediately terminate the 1953 easement and shut down Enbridge Energy Line 5 pipelines operating under the Straits of Mackinac.

Identifies multiple material breaches of easement conditions including pipeline wall thickness 41 percent below the 0.812-inch requirement, corrosion eroding up to 26 percent of thickness, and unsupported spans exceeding the required 75-foot anchor intervals.

Notes the 64-year-old pipeline transports nearly 23 million gallons daily of light crude oil and natural gas liquids at 80 percent above original specifications while lacking adequate emergency response plans.

States a University of Michigan 2016 study found a Line 5 rupture would likely contaminate at least 700 miles of coastline, while the Coast Guard cannot respond effectively to leaks in the Great Lakes, particularly under ice cover.

Argues that Enbridge's liability and surety bonds of $1 million and $100,000 respectively are insufficient compared to the company's $1.2 billion Kalamazoo River spill cleanup costs.
