(Ashland, WI) — The Wisconsin Department of Natural Resources is investigating a possible oil spill from a pipeline south of Ashland.
The owners of Enbridge Line 5 notified the state Wednesday that a contractor had found some apparently contaminated soil about a mile west of the Bad River Band of the Lake Superior Chippewa reservation.
Enbridge officials told D-N-R staff it believes the contamination was from a historical discharge and not a current leak. The soil was dug up and stored for inspection. An active leak hasn’t been found.
