Volunteers spotlight more groundwater problems apparently created during Line 3 pipeline construction

State environmental watchdogs are investigating, but not releasing any details

This a corrected version of an earlier blog. The original version incorrectly said the DNR and MPCA made a joint statement about the Walker Brook situation. This post includes their separate statements. The previous post has been taken down. I regret the error.

More environmental damage is coming to light from construction of the Enbridge Line 3 tar sands pipeline, and its due to citizen volunteers.

The group Waadookawaad Amikwag (Anishinaabe for “Those Who Help Beaver”) has been monitoring the construction corridor for unreported environmental damage out of concern that state regulators weren’t paying attention to it.

Waadookawaad Amikwag released a video this week of what they say is a fourth cold underground water breach, this one where Line 3 crosses Walker Brook South in Clearwater County.

The DNR denies that there is an aquifer breach, suggesting it is “an upwelling of shallow groundwater resources that has complicated site restoration.”

(The DNR’s statement is silent on the connection between Line 3 construction and the upwelling of shallow groundwater or how much groundwater has upwelled.)

This comes on top of three Line 3 aquifer breaches we already know about: Clearbrook, LaSalle Creek, and Fond du Lac.

All this environmental damage falls disproportionately on the Anishinaabe (Chippewa and Ojibwe) nations in northern Minnesota. In approving Line 3’s Certificate of Need, the Minnesota Public Utilities Commission “expressed serious concern with the Project’s impacts to indigenous populations, acknowledging that the Project would traverse ceded territories where Minnesota’s Ojibwe and Chippewa tribes hold … hunting, fishing, and gathering rights.”

Near fatal Line 3 accident seems to have been avoidable

Regulators shouldn’t have allowed a pipeline in this area

On Saturday, Feb. 6, a piece of heavy excavating equipment used for the Enbridge Line 3 pipeline corridor broke through the ice in Hubbard County. The operator was trapped in freezing cold water which nearly filled his enclosed cab. He was unable to exit and became hypthermic. A dramatic rescue followed, including the destruction of a beaver dam to drop the water level. The operator survived.

The incident occurred near a wetland by LaSalle Creek in an area known as the LaSalle Valley, located between Itasca State Park and the Mississippi Headwaters.

This problem was foreseeable.

Digging deeper into the story raises questions about whether state regulators were paying enough attention when they approved Line 3’s route through the valley.
