Enbridge’s ongoing response to incident at Cambridge Station

December 16, 2024

During a station walkthrough on the morning of Nov. 11, 2024, oil was discovered on the ground within the Cambridge Pump Station on Enbridge’s Line 6 liquids pipeline in south-central Wisconsin. Enbridge immediately reported the release to state and federal regulators and the National Response Center, and initiated investigation and remediation. We are working with the Wisconsin Department of Natural Resources (DNR) as cleanup and restoration proceed.

We estimate roughly 60% of the volume of oil released (960 barrels of an estimated 1,650 barrels) has been recovered so far through excavation of impacted soils within the pump station. Additional remedial measures are being evaluated and will move forward with approval from the Wisconsin DNR.

The release involved a faulty connection on a pump transfer pipe within the Enbridge Cambridge Station which has been repaired. Local landowners and government officials have been informed of our response, and we will continue to provide them with updates.
