State utility regulators on Thursday approved the environmental review of Enbridge's proposed new crude oil pipeline across northern Minnesota, a milestone for the controversial project.
By a vote of 5-0, the Minnesota Public Utilities Commission (PUC) deemed the environmental impact statement (EIS) for Enbridge's proposed new Line 3 to be "adequate." The PUC in December had voted 4 to 1 against the EIS, saying it was inadequate because of a handful of narrow concerns.
The PUC sent the report back to its author, the Minnesota Department of Commerce, to address its questions. PUC members said they were satisfied with the answers.
"The revised EIS before us addresses the significant environmental issues," said PUC Commissioner Matt Schuerger. The EIS looks at myriad potential environmental effects of a new Line 3 but made no conclusions.
In June, the PUC is scheduled to decide on a "certificate of need" for the project — essentially giving it a green light or killing it.
Environmental groups and Indian tribes that oppose Line 3 have criticized the EIS on several fronts, including not adequately assessing potential oil spills into sensitive waters or wilderness areas.
They continue to say the EIS is inadequate, and a legal challenge of the PUC's decision is in the offing. The environmental activist group Honor the Earth plans to appeal the ruling to the Minnesota Court of Appeals, according to Paul Blackburn, an attorney for the group.
"We believe the environmental impact statement doesn't fully address the impacts on the indigenous people of Minnesota and all of the people of Minnesota," Blackburn said.
