The company has now said the line is back. The incident site is not closed
Enbridge Inc. (TSX: ENB, NYSE: ENB) posted a September 14 Line 5 update at 11:03 a.m. Central Time. Over the weekend, the company said, teams safely returned Line 5 to service through a temporary bypass around the damaged section near Saxon, Wisconsin. Work at the site continues, focused on safe access, environmental testing, and remediation.
That is the first company confirmation that product is moving again. This morning's file still had the September 12 4:51 p.m. Central note, which said the bypass had passed its overnight pressure test and that return to service was underway. The September 11 note had targeted September 12. The Monday morning incident page had not yet moved.
Enbridge said it worked with the Pipeline and Hazardous Materials Safety Administration and local officials. It continues to work with the Wisconsin Department of Natural Resources on permitting and separately on environmental conditions. The DNR's September 9 letters asked the company to halt bypass construction. Enbridge's Monday note does not say the state withdrew that request.
Environmental monitoring continues. Wildlife has not been impacted, Enbridge said. Surface water and a nearby residential well continue to show no impacts. Water monitoring wells continue to show no contamination. The flatbed truck remains on site. A no-fly zone remains in effect per the Iron County Sheriff. Line 5 supplies 10 refineries and propane production facilities in the Midwest and Great Lakes, the company said.
Line 5 was isolated August 25 after an unoccupied subcontractor flatbed rolled into an excavation at a valve project and struck the pipe. The release was natural gas liquids, mainly propane and butane. No injuries were reported. Keyera had estimated a $30 million reduction to 2026 Marketing segment realized margin from the outage. Keyera has not posted a restatement since Enbridge called the restart.
Neutral read
ENB is on the listed pipeline list. Banks were skipped. A weekend bypass restart and an unfinished remediation site are the facts. Write this as a company-confirmed return to service, not as a closed incident. Watch whether Keyera lifts the $30 million marketing estimate and whether Wisconsin DNR posts a new permitting note.
