A federal review of plans for a Great Lakes oil pipeline tunnel will take more than a year longer than originally planned, officials said Thursday, likely delaying completion of the project — if approved — until 2030 or later.
The U.S. Army Corps of Engineers had intended to release a draft report later this year on how the proposed tunnel beneath Michigan's Straits of Mackinac would affect the environment. Enbridge Energy wants it to house a section of its Line 5 oil pipeline that crosses the bottom of the straits connecting Lake Huron and Lake Michigan.
