Tribal and environmental groups have sued the U.S. State Department for approving a temporary plan by a Canadian pipeline company to increase the flow of heavy crude oil from Alberta into Minnesota before a federal environmental study is finished.
The lawsuit, filed Tuesday in U.S. District Court in Minnesota, alleges that the State Department violated the National Environmental Policy Act and other laws in approving the temporary increase in oil flow and in not releasing information about it. The suit seeks an injunction to halt the project.
"It is a blatant attempt to avoid the ongoing State Department review process," Doug Hayes, staff attorney for Sierra Club, one of the groups behind the lawsuit, said on a conference call Wednesday. "It is an attempt to increase tar sands imports into the United States without any public scrutiny."
The State Department said by e-mail that its policy is not to comment on litigation.
Enbridge Energy won Minnesota regulatory approval in August to complete a $200 million upgrade of its 1,000-mile Alberta Clipper pipeline, boosting its flow by adding pumping stations. The line carries heavy crude from the Alberta oil sands region across the state, supplying refineries across the Midwest.
Part of the upgrade is already finished, but the State Department hasn't yet approved a presidential permit for Enbridge to legally increase cross-border oil shipments. That's the same permit needed for TransCanada's proposed Keystone XL pipeline through Western states, on which the Obama administration has not yet acted.
In a move that angered climate and environmental activists, Calgary-based Enbridge got approval from the State Department in July to increase its cross-border oil flows on the Alberta Clipper line by shifting the crude into another, underused pipeline at the border.
The underused pipeline, known as Line 3, already has a presidential permit to operate at higher volumes. It also carries Canadian crude to Midwest refineries, but operates at a reduced flow for safety reasons. The 1960s-era Line 3 suffers from corrosion and has ruptured several times, and Enbridge has announced plans to rebuild it by 2017.
