An internal document from Enbridge shows multiple issues with the support structure for line 5.
The document highlights over 200 structural problems on the controversial pipeline in recent years...
For every 75 feet under the Straits of Mackinac, there are supposed to be supports to keep Line 5 working properly, but that hasn't happened.
According to reports:
"According to the Underwater Inspection spreadsheet document, most of the spans over 75 feet were listed from 2005 to 2010 with some still in 2012.
Out of any of the years listed on the document, the longest span from one support to the next was listed as 54 feet over the 75-foot limit in 2005, along the east pipeline. The next longest span was 50 feet over the limit in 2005, along the northern part of the east pipeline.
Some specific spans are shown to have been in violation, in some cases, for at least five consecutive inspection years which occur every two years.
In total, the document reports nearly 250 instances between the east and west lines of Line 5 over the years where sections have spanned longer than the required 75 feet."
