MADISON, Wis. A lawsuit filed today in Wisconsin says state environmental officials should have done a better job studying the impact of a pipeline expansion across the state before giving the go-ahead.

The plaintiffs include the Wisconsin Wetlands Association, the Friends of St. Croix Headwaters and the River Alliance of Wisconsin. They argue the pipeline project could harm hundreds of acres of wetlands and forests.

Houston-based Enbridge Energy wants to lay a new, larger pipeline on an existing pipeline running from Superior to Delavan. The D-N-R has granted the company conditional approval.
