MINNEAPOLIS — Enbridge Energy disputed a state agency’s recommendation against the company’s proposal for replacing its aging Line 3 oil pipeline across northern Minnesota, insisting in filings Wednesday that the project is needed to ensure adequate crude supplies for Minnesota and other Midwestern refineries for decades to come.

The Minnesota Public Utilities Commission is considering whether to grant a certificate of need for the project, which has aroused opposition from environmental and tribal groups because of the potential impacts on climate change and pristine waters where Native Americans harvest wild rice. The state Commerce Department surprised both sides last month when it concluded that the project isn’t needed and that it won’t benefit Minnesota enough to justify the risks.
