The Department of Commerce reissued an amended final environmental impact statement for the Enbridge Line 3 pipeline on Monday after the agency fixed four “deficiencies” the Public Utilities Commission pointed out in December.

The PUC will accept comments through Feb. 27 “only on whether the revised final EIS adequately addresses the four specific deficiencies.”

Those had to do with karst topography; quantitative vs. qualitative representations; additive impacts and a clarification that “a traditional cultural properties survey must be completed before the start of any construction.”

Enbridge wants to build 337 miles of pipeline across the state on its route from Alberta to the company’s terminal in Superior, largely taking a route differing from the existing Line 3 and bringing capacity back to 760,000 barrels per day. The PUC is supposed to decide this summer if it will approve the pipeline, which has already begun construction in Canada and Wisconsin.
