(The Center Square) â The Minnesota Court of Appeals on Monday affirmed the stateâs Public Utilities Commission approval of the Line 3 Replacement Project. The Court of Appeals determined the MPUCâs approval of the Line 3 environmental impact statement, certificate of need and route permit were accurate. The 337-mile new pipeline replaces 283 miles of the current Line 3, and will span Minnesota from the North Dakota border to the Wisconsin border. âAfter six years of community engagement, environmental review, regulatory and legal review, itâs good to see confirmation of previous decisions on the Line 3 Replacement Project,â Vern Yu, Enbridge executive vice president and president Liquids Pipelines. âFrom the start, the project has been about improving safety and reliability for communities and protecting the environment.â
