After three days of hearings, state utility regulators seemed no closer to a final decision on a controversial new pipeline proposed for northern Minnesota.
The Minnesota Public Utilities Commission (PUC) on Tuesday juggled topics from financial guarantees for Enbridge's $2.6 billion proposal to replace its Line 3 pipeline, to oil demand and route alternatives for any new pipeline.
The five commissioners will go at it again Wednesday, aiming to end a three-year-plus regulatory saga by Friday.
"Each of the commissioners realizes the magnitude of the decisions they will make this week," said PUC Chairwoman Nancy Lange at the start of the meeting. That may explain the plodding pace of the day's proceedings.
Calgary, Alberta-based Enbridge said the new pipeline is a necessary safety measure. The 1960s-vintage Line 3 is corroding and can only operate at 51 percent of capacity due to safety concerns. A replacement pipeline would restore the full flow of oil to 760,000 barrels per day.
Environmental groups and several American Indian tribes oppose the project, saying a new Line 3 would exacerbate climate change and open a new region of Minnesota lakes, rivers and wild rice waters to degradation from possible oil spills.
Under Enbridge's proposal, the new pipeline would follow Line 3's current route to Clearbrook, Minn., then jut south toward Park Rapids before heading east to Enbridge's terminal in Superior, Wis. The stretch from Park Rapids to Superior currently hosts no pipelines.
Commissioners began talking Tuesday about possible route alternatives to Enbridge's preferred routes.
