“They assumed very good rock conditions, they assumed minimal groundwater inflow, they assumed no toxic gases or methane. Most importantly they assumed that the tunnel annulus, which is the space between the pipeline and tunnel wall, be completely filled or backfilled with concrete … none of those conditions came true…. They didn’t do nearly enough borings, they didn’t go nearly deep enough, and they didn’t take the samples where they should have. And despite all of those deficiencies in their study they came back—and the report is open to the public—the rock quality is extremely poor to very poor quality. They grade rocks from 0-100%. 25% of the rock was a zero …This is the worst rock I’ve ever seen anyone think about putting a tunnel in… because the rock is so bad it doesn’t behave like rock, it behaves more like gravel.”
I realize that there is a market for the petroleum products the tunnel would provide. I remain unconvinced, however, that the benefits in any way outweigh the dangers. This would be a terrible place for an accident to take place and Enbridge has a problematic record. Please do not allow the Line 5 Tunnel to proceed. As a proud Michigander, I highly value our Great Lakes, not only for their economic benefits (which are enormous) but for the life they support and the pleasure they give both locals and visitors.
Thank you
As a tribal citizen of Northwest lower peninsula of Michigan, I am greatly concerned about the continued use of the aging line 5 pipeline and also the proposed tunnel. The environmental impact on the land, water and all life is huge and the region is at risk. The benefits are small and the danger is great!
We depend on the water for so much, and it needs to be honored and protected for the present and future generations. The permit for the tunnel must not be given. In regards to the aging line 5 pipeline it must be decommissioned. We need to move forward with a healthier ,better vision,and action for the future generations!
