The Trump administration is advancing a rule change to give states control over air pollution public participation for minor sources like data centers, while also exempting dedicated power plants from acid rain regulations. Concurrently, President Trump criticized New York’s data center moratorium as Palm Beach County commissioners rejected a major AI campus expansion.
EPA Rule Changes Target Public Notice for Data Center Pollution Permits
The Trump administration is weighing a regulatory shift that could reduce public notification requirements for new air pollution sources, including the diesel generators and gas plants frequently built to power data centers. The Environmental Protection Agency held a public hearing on a proposal that transfers authority to state agencies to decide whether, when, and how communities participate in the permitting process for minor pollution sources. Major pollution sources undergo strict federal and state review, but minor sources—a broad category spanning dry cleaners to the fossil-fuel engines supporting data operators like xAI and Meta—face lighter oversight and varying state rules.
Organizers and legal advocates warn that stripping federal participation mandates could blindside neighborhoods. Vanessa Lynch, a Pennsylvania organizer with Moms Clean Air Force, testified at the EPA hearing that people want to have a say in developments arriving near their homes. Keri Powell, an attorney at the Southern Environmental Law Center, noted that organizations in states like Georgia rely on robust local permit applications to spot construction issues early, warning that removing federal requirements could leave communities with little to no advance notice of incoming facilities.
State agencies are responding differently across the country. Sara Lips, communications director for Georgia’s Environmental Protection Division, stated that her agency is determining whether the federal changes would impact state-level public participation regulations. Meanwhile, Byron Gary of the Kentucky Resources Council noted that Kentucky officials have made informal behind-the-scenes commitments to maintain existing public participation rules regardless of federal rollbacks, though future political shifts could alter that stance.
Acid Rain Regulations Waived for Islanded Data Center Power Plants
Alongside permitting adjustments, the administration has exempted power facilities that exclusively serve data centers from specific limits designed to prevent acid rain. According to reporting cited by Reuters, these islanded power stations will no longer fall under the Clean Air Act’s Acid Rain Program, freeing operators from mandated reductions in sulfur dioxide and nitrogen oxides. Nearly 60 such power plants are operating or under construction nationwide.

“Ensuring that the United States maintains our artificial intelligence dominance is essential to national security and economic prosperity,” EPA Assistant Administrator for Air and Radiation Aaron Szabo said in a statement published by The Hill. “The EPA is proud to further the President’s agenda through commonsense approaches to regulating.”

The agency defended the decision by noting that the Acid Rain Program targets traditional electric utilities rather than private power sources that supply isolated commercial facilities rather than the general public. Projections from Bloomberg indicate that data centers could consume 20 percent of national energy within the next eight years, raising environmental concerns regarding precursor gases that damage ecosystems and exacerbate respiratory and cardiac conditions.
Political Clashes Erupt Over New York Moratorium and Palm Beach Rejection
Disputes over infrastructure growth extend beyond federal rules into state and local politics. New York Governor Kathy Hochul instituted a one-year temporary moratorium on building new data centers consuming 50 megawatts or more, citing concerns over water use, energy demand, and air quality. President Trump criticized the pause on Truth Social, calling data centers cash cows for local economies and labeling the state’s decision terrible. Hochul fired back via social media, stating that communities powering artificial intelligence deserve a fair share of the success rather than scraps.

Local pushback also surfaced near President Trump’s Mar-a-Lago residence, where Palm Beach County commissioners voted 5-1 to reject an AI campus expansion known as Project Tango. Following more than 12 hours of debate driven by hundreds of local residents and community members, commissioners denied the application without prejudice, allowing developers to submit revised plans later.
“We are disappointed with the Commission’s decision. We reconfirmed our commitment to all conditions asked of us associated with our request and we addressed concerns through in-depth technical studies and analysis. We remain committed to helping meet the region’s growing critical infrastructure needs and will be taking time to evaluate our options moving forward.”
