After finding Enbridge’s final environmental impact statement (FEIS) on the Line 3 tar sands pipeline inadequate, the Minnesota Public Utilities Commission (PUC) has asked the state Department of Commerce to answer questions about pipeline’s underlying topography and to clarify some parts of its analysis. Minnesotans and several state agencies had raised serious concerns about the FEIS, which included numerous calculation errors, used Enbridge’s own data without any independent verification, and failed to adequately explore alternatives to this pipeline expansion or any no-build scenario. In spite of the FEIS, Minnesota’s Department of Commerce later submitted testimony to the PUC concluding that there is no need for Line 3. PUC gathered public input through various hearings on the proposed Enbridge pipeline through Nov. 22. The multi-billion pipeline project, the largest ever undertaken by Enbridge, will replace more than a thousand miles of the current Line 3 pipeline that carries crude oil from Alberta through Minnesota to Superior Wisconsin.
