Environmental groups sue DNR over environmental review process for Port Washington data center

Environmental groups sued the Wisconsin Department of Natural Resources (DNR) for allegedly skipping a required environmental review process for a $15 billion hyperscale data center in Port Washington. The lawsuit claims the DNR avoided requiring an environmental impact statement after Vantage, the project's lead company, threatened to abandon the project. The data center, built by Vantage, Oracle, and OpenAI, faces additional legal challenges over energy tariff requirements.
