EPA proposal would end federal public notice for data center air pollution permits

The US Environmental Protection Agency is moving to eliminate a federal requirement that gives the public notice and a chance to comment when certain industrial facilities apply for air permits, a change that according to The Verge would make it far harder for communities to learn about or object to new data centers before construction starts.

What the EPA is proposing

The rule in question is part of New Source Review, a permitting process in place since the 1970s that covers facilities ranging from landfills and paper mills to power plant expansions. With the rise of generative AI, these permits have increasingly become flashpoints for opposition to new data centers and to the power plants built to supply them with electricity.

In July, the EPA announced it would eliminate the federal public participation requirement for a large set of polluters and place that responsibility on states. State and local air agencies would decide whether to notify the public about certain new pollution sources at all, and advocates fear many would drop the process entirely. Federal involvement has traditionally been justified because air pollution can drift across state lines, affecting people far from its source.

EPA administrator Lee Zeldin defended the move in a statement, arguing that state and local authorities closest to the issues should make permitting decisions rather than Washington, and framed the change as cutting unnecessary red tape.

The proposal applies to so-called "minor" sources of pollution, which the EPA describes as having relatively low emissions and limited environmental impact.

Why the "minor" label is contested

Environmental groups argue the category is a misnomer that routinely captures projects with serious consequences for their neighbors. Keri Powell, senior attorney and air program leader at the Southern Environmental Law Center (SELC), told The Verge that the change would let facilities obtain permits without public input: "Nobody knows what's happening until the bulldozers are out there."

The category already covers flagship AI infrastructure. xAI's Colossus 1 data center in Tennessee, billed by the company as its most powerful AI training system, applied for a minor source permit in 2025. As Inside Climate News reported, the public notice for that application drew thousands of comments and prompted a hearing. That same year, the SELC and NAACP threatened to sue xAI over gas turbines installed at the site without permits.

Opposition and what happens next

SELC was one of nearly 200 health and environmental groups that filed comments asking the EPA to withdraw the proposal. They argue that public participation is not merely procedural: residents can supply permitting agencies with local knowledge that no one else can.

Byron Gary, senior attorney at the Kentucky Resources Council, said in a press release that the proposal could deprive agencies of the lived experience of affected communities, making it impossible for them to evaluate the full cumulative impact of new facilities.

The formal comment period has now closed. EPA spokesperson Carolyn Holran told The Verge that the agency is still reviewing the more than 4,900 comments that must be addressed before the rule can be finalized.

Why it matters

Data centers are being built at extraordinary speed to serve generative AI, and many depend on on-site gas turbines or dedicated fossil fuel generation that falls within these permitting categories. If the rule is finalized, residents near new facilities would lose their only guaranteed opportunity to learn about and challenge pollution sources before they are built, unless their state voluntarily maintains notification requirements. For developers, fewer procedural steps could mean faster permitting timelines, one reason advocates see the change as aligned with the administration's push to accelerate AI infrastructure construction. More broadly, the outcome will help determine who gets a say in where the physical footprint of AI is allowed to land.
