Enbridge Pauses Construction of $1B Pipeline in Wisconsin
Enbridge (ENB) has paused construction of a $1B pipeline in Wisconsin after an incident involving a third-party truck striking a bypass valve. The pause, requested by the state's DNR, will last two days. The pipeline is part of a network transporting oil and gas from Canada. Enbridge is addressing a spill of 2,000 barrels of natural gas liquids, with 31,000 barrels already vaporized. The DNR has requested Enbridge provide plans for controlling and mitigating the vapor release.
