Cottage Grove OKs EIS for riverbed mine

The Cottage Grove City Council voted 5–0 on Nov. 6 to deem adequate the final environmental impact statement for Amrize Nelson’s proposal to shift and expand sand-and-gravel mining into the Mississippi River backwaters near Lower Grey Cloud Island, moving the project to state and federal permitting. Friends of the Mississippi River objected, arguing shoreline mining is illegal under MRCCA rules, while the mayor said the three‑year review only assessed EIS adequacy; the expansion would tap about 400 acres and extend mine life by 20–25 years.
