EPA steps back from AI data center regulations

The U.S. Environmental Protection Agency (EPA) has declared it will not establish federal standards or regulations for new data centers, opting instead to delegate regulatory authority to individual states and communities. This announcement coincides with an EPA proposal to eliminate public input and comment opportunities for minor clean air pollution permits. These permits are frequently utilized by data centers, particularly for backup diesel or on-site natural gas generators.

Cyrus Reed, legislative and conservation director at the Sierra Club Lone Star chapter, voiced strong opposition to the EPA's proposal. He highlighted that data centers often rely on numerous minor permits for their diesel and gas generation facilities, which can cumulatively emit significant pollution. Reed cited an analysis in Virginia, which estimated potential emissions of 13,000 tons of nitrogen oxide and 650 tons of particulate matter in mainly rural communities from such facilities. He criticized the move as reducing transparency and preventing the public from addressing the cumulative environmental impact that states and the EPA often overlook when issuing individual minor permits.

Reed also noted that while the federal decision wouldn't prevent states like Ohio from maintaining their own public participation rules, it removes a critical federal backstop. He warned that states like Texas, from his experience, tend to revert to minimum standards when federal requirements are absent, likely leading to a reduction in public process. He emphasized the health risks associated with these pollutants, including the formation of ozone and smog from nitrogen oxide, which harms respiratory tracts, and particulate matter, which can cause premature deaths, especially in vulnerable populations.
