FBI Investigating Fires at Two Enbridge Facilities in Wisconsin

Green Bay Appleton, WI, September 23, 2026 —

The Federal Bureau of Investigation (FBI) has confirmed it is investigating two separate fires that took place last week at locations associated with Enbridge in Wisconsin. The incidents involve a drill site related to the company’s Line 5 reroute project in Ashland County and Enbridge’s office facility in Superior.

Details regarding the specific dates the fires occurred were not immediately available, beyond them happening within the past week. Authorities have not yet released information about the cause or extent of damage for either incident. The FBI’s involvement indicates the potential seriousness of the events as investigations commence.

One fire occurred at a drill site connected to Enbridge’s ongoing efforts to reroute its Line 5 pipeline. The Line 5 pipeline is a significant piece of energy infrastructure that transports oil and natural gas liquids across the Great Lakes region. Rerouting projects for such pipelines are often complex and can be subject to regulatory scrutiny and public debate.

The second fire was reported at Enbridge’s office in Superior, Wisconsin. Further details about the number of personnel affected, if any, or the operational impact of this fire have not been disclosed.

The contractor’s name for the drill site operations was not provided. Similarly, specific outcomes of any preliminary inspections or details about potential code violations or fine amounts were not made public in the provided information. The FBI has stated its investigation is ongoing and has not offered further comment on the scope or findings at this time. Information regarding what happened next, such as the timeline for the investigation or any potential charges or findings, is also not yet available.
