The U.S. Army Corps of Engineers will fast-track permits for building a protective tunnel around an aging Enbridge oil pipeline that runs beneath a channel connecting two Great Lakes.

The move comes after President Donald Trump issued an executive order in January declaring that the U.S. has become too dependent on foreign energy sources. The order mandates that federal agencies identify energy infrastructure projects for expedited emergency permitting from the U.S. Army Corps of Engineers and the Environmental Protection Agency.

The corps designated the tunnel project on Line 5 as an emergency under the order late Tuesday. The corps had initially planned to make a permitting decision early next year. Corps officials were vague during a conference call with reporters Wednesday morning about how quickly the process may move forward.
