Four Michigan state agencies have expressed concerns about the condition of Enbridge's LIne 5, which carries crude oil and natural gas from Wisconsin to Ontario.The line is 64 years old and the quality of its lining is what in question.

The four agencies (The Michigan Agency for Energy, Michigan Departments of Environmental Quality and Natural Resources and the Michigan State Police) say new information confirms gaps exist in the protective coating on a portion of Line 5 in the Straits of Mackinac.

Based on these concerns, The Detroit News reports the state is demanding immediate inspections of the areas around every anchor on Line 5, a report to the DNR and DEQ of any findings from the inspections, a copy of the video of the recent work performed on the pipeline, and repair within 30 days of any damage to the pipeline’s coating.

Governor Rick Snyder ordered an "aggressive review" of the situation and issued this statement late Wednesday afternoon:

“Protection of Michigan’s natural resources is of utmost importance, and I am greatly concerned by the new information regarding Line 5. I have directed our departments to accelerate an aggressive review of Enbridge operations and maintenance procedures throughout the state.”

According to the state's website, Line 5 is a 645-mile pipeline built in 1953 and runs from Superior, Wisconsin, to Sarnia, Canada. It transports up to 540,000 barrels a day of light crude oil and natural gas liquids.

This is not the first time Enbridge has been in the news regarding the pipelines.
