State officials ordered the inspections after a spokesman for the Canadian company said last month that Enbridge engineers knew in 2014 that the installation of a support anchor that year damaged coating on the pipeline but the company remained silent because company engineers did not deem it a safety issue.
Enbridge must present updated information to the Pipeline Safety Advisory Board’s Dec. 11 meeting about the conditions of its pipeline, coating that protects from corrosion and anchors as well as the results of its video inspections and testing, state officials said in a statement.
“A year ago, Enbridge said there were no coating gaps in the straits pipeline. Now, there are dozens,” said Valerie Brader, executive director of the Michigan Agency for Energy and an advisory board co-chair, in a Monday statement. “When will we know the full accounting of what Enbridge knows about Line 5?”
