Enbridge said an early morning fire destroyed a drill rig and support equipment on a $1 billion project to reroute its Line 5 oil and gas pipeline in northern Wisconsin.
In a statement, Enbridge spokesperson Juli Kellner called the fire that damaged a horizontal directional drill rig and related equipment an act of vandalism. She said there was also graffiti found at the site. No details were provided on where the fire took place, but Kellner said no injuries were reported.
Iron County Sheriff Paul Samardich confirmed the blaze occurred in Ashland County. The Ashland County Sheriff’s Office did not immediately respond to requests for additional details on the fire.
The incident follows two other fires targeting Enbridge that occurred last month, including a blaze in
Ashland County that destroyed a drill rig on the Line 5 reroute.
“This is the second major vandalism involving construction equipment on the project,” Kellner said.
“These incidents put the local community, landowners, first responders and our workers at risk and result in environmental impacts.”
The FBI and federal Bureau of Alcohol, Tobacco, Firearms and Explosives, or ATF, are investigating the cause of the two previous fires that occurred in the Town of Gingles and the city of Superior.
Representatives of the FBI and ATF did not immediately respond to requests for comment.
Kellner said Enbridge supports people’s rights to express their views “legally and peacefully.”
“Acts that damage property and put people or the environment at risk are neither legal nor peaceful,” Kellner said. “We take these incidents very seriously and will cooperate fully with authorities as they investigate and seek to hold those responsible accountable.”
Enbridge’s Line 5 pipeline carries up to 23 million gallons of oil and natural gas liquids daily from Superior to Sarnia, Ontario, serving 10 refineries and propane facilities in the Great Lakes region.
The fires come after an Aug. 25 gas leak on Line 5 in the town of Saxon released more than 1.3 million gallons of natural gas liquids into the atmosphere. Preliminary findings suggest a subcontractor’s truck was in neutral when it rolled into an open construction trench, striking the pipeline. No one was injured in the incident, and response to the spill is still ongoing.
Following the leak, the Wisconsin Department of Natural Resources asked Enbridge to halt work on a temporary bypass around the site of the leak, saying the company lacked necessary approvals.
On Sept. 28, Enbridge also reported a release of groundwater at a site where crews were directly installing pipe underneath the Marengo River. Initially reported as an aquifer breach, the DNR has since said it’s still investigating the source of the release and determining any negative effects to groundwater.
