This fragmentation keeps reported emissions below the 100-ton-per-year
Environmental groups say major technology firms are exploiting loopholes in federal permitting to avoid strict emissions reviews for new data center projects. These facilities require federal air permits due to their potential to release pollutants like nitrogen oxides and particulate matter. Advocates claim companies are splitting emission sources across multiple applications to stay below thresholds that trigger more rigorous scrutiny. The strategy involves breaking down large projects into smaller components, each reported separately in permit filings. By doing so, developers argue individual components do not qualify as majorsources under EPA regulations, thus avoiding mandatory pollution control technology and public comment periods. Environmental advocates warn this practice undermines air quality protections and allows cumulative impacts to go unassessed. How companies are avoiding major source classification Developers are submitting permit applications that treat interconnected systems—such as backup generators and cooling plants—as independent units.

Critics say the approach ignores the reality that these systems operate together as part of a single facility. The EPA’s current rules allow such segmentation if facilities are not physically or functionally connected, but advocates argue data center components are inherently interdependent. What are the risks of fragmented permitting? Splitting permits makes it harder to assess the total pollution burden on nearby communities, especially in regions already facing industrial pollution. Environmental lawyers note that cumulative effects on respiratory health and local ecosystems may be overlooked when each piece is reviewed in isolation. There is also concern that this tactic sets a precedent for other energy-intensive industries seeking to evade accountability.
Regulators have not yet issued formal guidance addressing this specific pattern in data center permitting. Frequently Asked Questions Why are data centers subject to air pollution permits? Data centers use diesel generators for backup power and large cooling systems that can emit nitrogen oxides, sulfur dioxide, and particulates, triggering federal permitting requirements under the Clean Air Act. Can the EPA stop developers from splitting permit applications? The EPA can challenge applications if it determines the fragmentation is artificial and designed to evade major source rules, but enforcement depends on case-specific evidence of intent and functional integration. What could happen if this practice continues? Unchecked emissions growth could worsen air quality in host communities, increase health risks, and lead to legal challenges that delay or block future data center expansions.
