The EPA is done treating data centers like a monolith. Administrator Lee Zeldin announced on September 18, 2025, that his agency will evaluate data center projects individually rather than applying blanket regulatory frameworks, a move designed to fast-track the permitting pipeline for AI infrastructure across the US.

Starting September 29, 2025, the EPA will prioritize reviews of new chemical submissions under the Toxic Substances Control Act for qualifying data center projects. The decision aligns with the Trump administration’s broader push to remove friction from AI development, though it has already attracted pointed criticism from at least one Democratic senator.

What the new approach actually looks like

Zeldin has been personally visiting data center sites to understand the differences firsthand. On August 29, 2025, he toured Microsoft’s data center in Wyoming and met with representatives from Crusoe and Tall Grass, two companies developing an AI data center campus with a planned capacity of 1.8 gigawatts. For context, that’s enough power to supply roughly 1.4 million homes.

He’s also shown up at a $4 billion Google data center project in Arkansas, where he emphasized that power agreements need to be structured on a project-specific basis.

The case-by-case framework extends to air permitting under the Clean Air Act as well. Zeldin has signaled that the EPA is considering flexible, site-specific approaches to Clean Air Act compliance for data centers, rather than applying uniform standards.

The Crusoe connection and crypto’s pivot to AI

Crusoe originally built its business on capturing flared natural gas from oil producers and using it to power Bitcoin mining rigs. In March 2025, Crusoe sold its entire Bitcoin mining operation to NYDIG, a digital assets firm, to go all-in on AI infrastructure. The Wyoming campus that Zeldin visited is part of that pivot, a massive facility designed to serve the compute demands of AI model training and inference.

The political and environmental pushback

Not everyone is buying what Zeldin is selling. Senator Ed Markey has criticized the approach, arguing that flexible air permitting could effectively create loopholes in Clean Air Act requirements. His concern: that the urgency around AI development is being used as justification to weaken environmental standards that took decades to establish.

What this means for investors

The pivot from crypto mining to AI infrastructure, exemplified by Crusoe’s sale of its Bitcoin operations to NYDIG in March 2025, signals where institutional capital is flowing. Google’s $4 billion Arkansas project is one data point in what’s becoming a nationwide push for suitable data center sites.

The risk sits in the political uncertainty. If the flexible permitting approach faces legal challenges or gets rolled back by a future administration, projects that received expedited approval could face retroactive compliance requirements. Investors should watch state-level utility commission decisions as closely as federal permitting changes, because the power bottleneck is often more binding than the regulatory one.
