Line 5 Missed the September 5 Restart Window. Enbridge Is Now Aiming for Tuesday

Line 5 remains shut after the August 25 Wisconsin NGL release. Enbridge's September 3 update targeted return between September 6 and 8. September 4 media reports said the company now hopes to restore service Tuesday September 8 after missing the prior Saturday target.

The pipe is still down on the day the old window closed

Enbridge Inc. (TSX: ENB, NYSE: ENB) has kept Line 5 shut since August 25, when an unoccupied subcontractor flatbed truck rolled into an excavation at a valve project in Iron County, Wisconsin and struck the pipe. The release was natural gas liquids, mainly propane and butane, not dry gas. No injuries were reported.

In a September 3 incident update, Enbridge said restoration plans were progressing toward safely restoring service between September 6 and 8. That window superseded an earlier September 5 target. September 4 reporting, including Wisconsin Public Radio, said Enbridge now hopes to restore service on Tuesday, September 8, after compressed-air work to evaporate remaining liquids in the excavation.

Enbridge said September 3 that surface water and a nearby residential well showed no impacts, with air monitoring safe outside the evacuation zone. Keyera separately estimated a $30 million hit to 2026 Marketing margin from the outage.

Line 5 serves Midwest and Great Lakes refineries and propane facilities on the route from Superior, Wisconsin to Sarnia, Ontario.

Neutral read

ENB is on the listed pipeline list. Banks were skipped. A missed September 5 restart and a Tuesday September 8 hope are the facts. Write this as an outage extension, not as permanent capacity loss. Watch whether service actually returns September 8 and whether Sarnia NGL fractionators see deferred volumes into mid-September.
