Enbridge restores Line 5 service via bypass after Wisconsin spill

Enbridge has restored service to its Line 5 pipeline using a temporary bypass around a damaged section near Saxon in Iron County, Wisconsin. The shutdown followed an August 25 incident where an unoccupied semi-truck rolled into an open excavation site, striking the pipe and releasing natural gas liquids.

Enbridge stated that environmental testing and remediation efforts are ongoing at the site. The company reported that water monitoring from nearby residential wells and surface water shows no contamination, and no wildlife has been impacted. Work continues regarding soil removal and disposal within the trench.

The resumption of service follows recent tension with the Wisconsin Department of Natural Resources (DNR). The DNR had previously issued a letter requesting that Enbridge pause bypass work due to a lack of state approvals. DNR Secretary Karen Hyun noted that the company has demonstrated a “disregard for the environment, human health, and the statutory authority of the department” through a series of environmental concerns and violations.

Line 5 is a major pipeline transporting up to 23 million gallons of crude oil and natural gas liquids daily between Superior, Wisconsin, and Sarnia, Ontario. The project has faced ongoing legal challenges from the Bad River Band of Lake Superior Chippewa and various environmental groups.
