Summary
In August, an unoccupied flatbed truck operated by a subcontractor rolled into an open excavation site during a valve project on Enbridge's Line 5 pipeline in Iron County, northern Wisconsin, striking and puncturing the pipeline. Approximately 33,000 barrels (more than 1.3 million gallons) of natural gas liquids were released; most vaporized into the air, with 165 barrels recovered by vacuum truck. Enbridge shut down the pipeline and isolated the affected section within three minutes. One nearby rural residence was evacuated as a precaution, and no injuries were reported. The company reported the incident to the National Response Center within an hour. Environmental monitoring—including community air quality, monitoring wells, and soil and water testing—has shown no contamination or unsafe conditions outside the incident site. The estimated cost is at least $15.1 million. The cause of the truck rolling into the trench remains under investigation, with the Pipeline and Hazardous Materials Safety Administration (PHMSA) conducting ongoing investigations including mechanical and metallurgical analysis of the failed pipe section and inspection of the truck involved. PHMSA may pursue additional enforcement action if violations are identified.
