Sierra Club Wisconsin and MEAfte File Lawsuit After State Regulators Abandon Required Environmental Review for Port Washington Data Center
Sierra Club Wisconsin and Midwest Environmental Advocates (MEA) have filed a lawsuit against the Wisconsin Department of Natural Resources (DNR) for issuing permits for a large data center in Port Washington without a full environmental review. Emails showed the DNR reversed its decision to require a detailed Environmental Impact Statement (EIS) after developers complained, despite the project's significant environmental impact. The lawsuit demands transparency and accountability for the project, which involves Vantage Data Centers, Oracle, and OpenAI.
Midwest Environmental Advocates (MEA), representing Sierra Club Wisconsin, has filed a lawsuit challenging the Wisconsin Department of Natural Resources' (DNR) decision to permit a massive data center campus in Port Washington without a comprehensive environmental review. The lawsuit emerged after public records revealed that DNR staff initially deemed a detailed Environmental Impact Statement (EIS) necessary due to the project's scale. However, the DNR reversed course, opting for a more limited 'environmental analysis summary' after data center representatives expressed concerns that an EIS would 'kill the project,' a decision the agency has not publicly explained.
The project, spearheaded by Vantage Data Centers, Oracle, and OpenAI, is a $15 billion hyperscale data center in Port Washington, one of Wisconsin's first. Its first phase alone is projected to require 1.3 gigawatts of power, capable of powering over half a million households. Environmental groups highlight that this massive energy demand will necessitate the construction of new gas plants, substations, and high-voltage transmission lines across six counties, including the new Foundry Ridge gas plant in Walworth County. This contradicts the project's public-facing materials that emphasize renewable energy development, raising concerns about transparency and increased fossil fuel emissions.
Elizabeth Ward, Sierra Club Wisconsin Chapter Director, emphasized the unprecedented nature of the data center's impact on the local landscape and its substantial consumption of electricity and water, warning against long-term decisions that increase greenhouse gas emissions. MEA attorney Michael Greif underscored the public's right to understand why the state deviated from standard environmental review procedures for such a significant development. The lawsuit aims to compel accountability and ensure a thorough evaluation of the data center's direct, indirect, and cumulative environmental impacts, particularly concerning its energy infrastructure.
