DNR allows Enbridge to draw more groundwater

In January, Enbridge realized that it had vastly underestimated the amount of water needed for temporary trench dewatering during construction.

Dewatering is necessary when constructing a pipeline through wet areas. Excess water must be drawn out from the trench to protect workers and stabilize the soil. The water is later discharged back into the ecosystem. The appropriation of groundwater for dewatering requires a DNR (Minnesota Department of Natural Resources) permit.

New Construction Activity in Savanna State Forest

Watch the Line monitors recently observed pipeline staged through Savanna State Forest, a couple miles east of Highway 65.

Monitors have recently observed what looks like recent construction activity within the western area of Savanna State Forest, east of the AK-12 marker on our online map. Photos indicate digging and/or removal of topsoil, as well as staged pipes. Numerous signs indicate wetlands are present in and around this construction zone.

Preparing to monitor Line 3 horizontal directional drilling

Aerial view of site preparation for Line 3’s underground crossing of the Shell River.

Enbridge Line 3 would travel 337 miles across northern Minnesota, crossing 200+ waterbodies along the way. In most cases, Enbridge plans to trench through them. At 21 different crossings, Enbridge is going to tunnel underneath the waterbody, using a process called Horizontal Direction Drilling (HDD).

Enbridge will use HDD to tunnel under the Mississippi River at two separate locations.

Watch the Line monitors have seen the preparation work at several sites. Here’s what we’ll be looking for when the company is getting ready to drill.

Welcome to the Watch the Line Blog

Watch the Line MN is a citizen-led effort to lawfully monitor construction of the Enbridge Line 3 tar sands pipeline through northern Minnesota. We oppose this pipeline as a threat to the water and land, a violation of Anishinaabeg treaty rights, and a dangerous escalation of climate change. Our volunteer monitors have been traveling along the Line 3 route since construction began in December 2020, documenting the environmental damage. We have published all of our observations for public use.

With this blog, we intend to engage our volunteer monitors, alert the broader coalition opposed to Line 3, and inform the public about matters relating to Line 3 construction. We will provide updates on construction, interpretations of our observations, educational resources, and more.

We invite you to send comments, questions, or ideas for future posts to watchthelinemn@gmail.com.
