ST. IGNACE, Mich. (AP/WOOD) — A member of Congress from Michigan wants a federal investigation that could lead to shutdown of twin oil pipelines beneath the waterway where Lakes Huron and Michigan converge.

Legislation introduced by Republican Rep. Candice Miller would require an 18-month study by the Pipeline and Hazardous Materials Safety Administration to determine whether Enbridge Co.’s Line 5 poses a significant risk to the Great Lakes. If so, it would be deactivated.

Line 5 transports 23 million gallons of crude oil and liquid natural gas daily through the Upper Peninsula and ends in Sarnia, Ontario. It divides into two smaller lines beneath the scenic Straits of Mackinac.

Miller says a rupture of the 63-year-old pipeline would have a “catastrophic impact” on the lakes.

In a statement released to 24 Hour News 8 Friday, Enbridge said Line 5 is operated safely and monitored constantly.

“Enbridge recognizes PHMSA’s authority to review the risks and safe operations of our pipelines.

We are committed to protecting the Straits, and Great Lakes, through the continued safe operation of line 5, which was built to protect the Straits.

We inspect Line 5 more frequently than required by regulation, monitor the pipeline 24/7 with dedicated teams and work diligently to maintain the pipeline to the highest safety standards.

We will continue engaging with the members of the Michigan Congressional delegation to make sure they have factual information about Line 5 and the hard work of our employees and contractors to protect the Straits, Great Lakes and other sensitive areas.”
