Wisconsin DNR Alleges Line 5 Reroute Violations After Third Fire
Wisconsin regulators issued Enbridge a notice of violation Oct. 13 over its Line 5 reroute, the same day a third fire hit a pipeline construction site in Ashland County. ENR reports the alleged breaches span water, wetlands, air and stormwater.
Market Impact
The Wisconsin Department of Natural Resources says the alleged violations occurred between March 30 and Sept. 21. They include breaches of permit conditions and state law covering water quality, wetlands, navigable waterways, air quality, stormwater and endangered resources. The notice also alleges Enbridge built an unpermitted bypass around the site of an August spill in Iron and Ashland counties. That spill released more than 1.3 million gallons of propane and butane vapors near Saxon, Wis.
The agency has scheduled an enforcement conference with Enbridge. It says it could issue citations or refer the case to the Wisconsin Department of Justice, which could seek financial penalties and court-ordered remedies. The DNR is still reviewing incidents after Sept. 21, including a groundwater release under the Marengo River that surfaced in late September during pipe installation through a completed borehole. A DNR spokesperson said installation at that site is finished and containment measures are in place. The cause is not yet known.
The Aug. 25 incident began when an unoccupied, parked, third-party-owned semi-truck delivering equipment rolled into an excavation and struck a bypass valve. Enbridge was adding the valve to tie the existing line into the new one. The existing line was down about 10 days.
The Oct. 13 fire, reported around 5:20 a.m. in White River, involved an equipment trailer and two boring machines. No one was hurt, and the Ashland County Sheriff’s Office says cause and origin are under investigation. The FBI is investigating two mid-September fires. Enbridge spokesperson Juli Kellner said the company is reviewing the notice and condemned the fires as “neither legal nor peaceful.”
What It Means for Subcontractors
- Audit your March 30 to Sept. 21 records. That is the window the DNR cites. Pull daily logs, stormwater inspections, and wetland and waterway crossing records for any work you did on the 41-mile reroute. Enforcement could reach conduct after Sept. 21, so keep those records too.
- HDD and boring crews: lock down equipment. Both the Oct. 13 fire and one mid-September fire involved a trailer and two boring machines. The source does not say how they started. Our inference: confirm fueling, parking and overnight security practices now, and check that your insurer covers fire loss at remote drill sites.
- Treat bypass and tie-in work as a permit item. The DNR alleges the post-spill bypass was unpermitted. Get written confirmation of permit coverage before starting any emergency or unplanned work, and keep a copy of it.
- Control delivery traffic near open excavations. The Aug. 25 strike involved a parked, unoccupied semi. Require wheel chocks, set staging distances from excavations and live valves, and brief third-party drivers.
- Review indemnity and stop-work language. The source does not say who bears liability if penalties follow. Our inference: if the DNR seeks financial penalties through the Wisconsin DOJ, owners may look to contractors whose scopes touch cited conditions. Read your flow-down clauses before the enforcement conference, whose date the source does not give.
