Enbridge has to clean up water it polluted decades ago in order to use it for Line 3 dewatering

Enbridge’s controversial plans to increase dewatering during Line 3 construction got an added complication: Workers need to dewater in areas where the company had past crude oil spills, leaving 8,400 gallons in ground for decades.

That means Enbridge has to treat the dewatered polluted water before returning it to the environment.

Enbridge has spilled at least 10,000 gallons of drilling mud into MN streams, wetlands, and uplands, MPCA says

Enbridge has had at least 28 “frac-outs” while tunneling under Minnesota streams and wetlands to install its Line 3 tar sands pipeline. These have released between 10,000 and 13,000 gallons of “drilling mud,” according to data released by the Minnesota Pollution Control Agency (MPCA).

The drilling process requires using a special drilling mud that helps lubricate and cool the drill bit. The mud is under pressure and can get forced into subsurface soil cracks and pushed to the surface. This is called a frac-out. They can happen on land, in wetlands and in rivers and streams.

Line 3 drilling under the Mississippi River in Aitkin County resulted in the largest single spill, estimated between 6,000 and 9,000 gallons. It occurred in a wetland about a quarter-mile from the river, the MPCA said.

As Enbridge races to finish Line 3 construction, more suspected frac-outs

Water Protector Shanai Matteson points to the Willow River frac-out. Screengrab from Honor the Earth video.

On July 6, water protectors found an Enbridge Line 3 frac-out at the Willow River.

On Monday, Honor the Earth reported a suspected Line 3 frac-out at the Shell River. [Update July 22: The MPCA says there was no frac-out on the shell. It did report that Enbridge has had frac-outs at nine different construction sites. Updated blog coming soon.]

Today, the Indigenous Environmental Network reported a suspected Line 3 frac-out near the Mississippi headwaters. (Video here.)

Details of the frac-outs are still coming in.

It’s possible to see frac-outs on the surface of rivers and wetlands. There could be other frac-outs below the surface that remain unseen.

How many frac-outs will it take for state regulators to require something different, or do they dismiss frac-outs as an acceptable environmental cost?

Latest PolyMet court decision again highlights the MPCA’s failure to do its job

The Minnesota Pollution Control Agency’s (MPCA’s) mission is to protect and improve the environment and human health. It’s supposed to be the state’s leading environmental watchdog. But it’s been the kind of watchdog that, when a robber enters the room, it rolls over on its back in hopes of getting a belly rub.

The courts are doing more to protect our environment than the MPCA. That’s backwards. The MPCA should be in court pushing for more environmental protection.

The latest MPCA embarrassment came in the form of a Minnesota Court of Appeals ruling Monday that rejected the air quality permit the agency approved for PolyMet’s proposed copper-sulfide mine.

Water protectors highlight Willow Creek frac-out, and the out-of-whackness of state Line 3 regulators and law enforcement

A government-Enbridge alliance is doing all it can to block Minnesota citizens from observing and critiquing the construction of Enbridge Line 3 tar sands pipeline.

Tania Aubid, Winona LaDuke, Shanai Matteson and other water protectors arrived around 7 a.m. this morning at the site where Enbridge is drilling a tunnel for Line 3 under the Willow River in Aitkin County. The water protectors found what appeared to be a “frac-out,” the release of pipeline drilling mud into the river.

The state’s response focused more on trying to intimidate the water protectors for their activism than addressing the frac-out, Matteson said.

It’s a sign of the state’s upside down values. It raises questions about the state’s ability and interest in protecting the environment for future generations and who state agencies are working for.

Revisiting the PUC’s tortured logic to approve Line 3 regardless of its massive climate damage

The Minnesota Public Utilities Commission (PUC) wrote in its Certificate of Need for Enbridge Line 3 that benefits of approving it outweighed the costs.

It could only come to that conclusion by completely ignoring climate damage.

There are clear signs in the record that Commissioners were grasping at straws to justify approving Line 3 in spite of its clear and significant climate damage.
