Datacenter Developers Skirt US Pollution Rules, Advocates Claim 2026

Datacenter developers are manipulating the EPA’s air pollution permitting process to avoid emission controls and scrutiny of their projects, environmental advocates allege. Companies need federal permits to emit a range of pollutants, but some in big tech are avoiding “major” reviews by dividing their emissions sources into separate, multiple “minor” sources that require less regulatory oversight, the advocates say.

How Datacenters Bypass Major Pollution Reviews

Under the Clean Air Act, facilities that emit pollutants above certain thresholds must obtain a major source permit, which involves rigorous review, public comment periods, and potential pollution controls. To avoid this, datacenter developers are accused of splitting their emissions sources into smaller units, each falling below the major source threshold. This allows them to apply for minor source permits, which are approved faster, with less scrutiny and fewer requirements.

This practice, known as source disaggregation, is not illegal if the sources are truly independent. However, advocates argue that datacenters are artificially dividing what is essentially a single project to sidestep regulations. “It’s a loophole that allows them to pollute more while avoiding accountability,” said one environmental lawyer.

Case Studies: North Carolina and New Mexico

In North Carolina, Amazon and utility giant Duke Energy are installing 649 diesel generators to back up a new hyperscale datacenter. They submitted two separate permits and avoided a major review, despite being located in a low-income area that already suffers from high levels of air pollution. Similarly, in New Mexico, the Project Jupiter datacenter developers attempted to circumvent a major review by proposing two natural gas “microgrids” on either side of the facility and submitting two “minor” permits. The overall project would have released enough pollution to trigger a major review.

These cases highlight a growing trend where datacenter developers exploit regulatory gaps to fast-track projects, often in communities already burdened by pollution.

Environmental and Community Impact

Datacenters can be significant sources of nitrogen oxide, ozone, heavy metals, particulate matter, greenhouse gases, and other dangerous air pollutants. When major reviews are avoided, these emissions go unchecked, exacerbating air quality issues and contributing to climate change. Low-income and minority communities are disproportionately affected, as they are often chosen for such projects due to cheaper land and weaker political opposition.

“These communities are already overburdened. Adding more pollution without proper oversight is environmental injustice,” said a spokesperson for a local advocacy group.

Key Takeaways

• Regulatory loophole: Datacenter developers split emissions sources to avoid major EPA reviews.
• Faster approvals: Minor permits require less scrutiny and are approved more quickly.
• Community impact: Low-income areas face increased pollution and health risks.
• Legal but controversial: The practice may comply with the letter of the law but violates its spirit.
• Call for reform: Advocates urge the EPA to close the loophole and enforce stricter oversight.

Comparing Major vs. Minor Permits

The Path Forward

Environmental advocates are calling on the EPA to revise its permitting rules to prevent source disaggregation. They argue that the agency should consider the cumulative emissions of a project, rather than allowing developers to slice them into smaller pieces. Some states, like California, have already implemented stricter rules, but a federal solution is needed to ensure consistent enforcement.

In the meantime, communities are fighting back. In North Carolina, local groups have filed lawsuits challenging the permits, arguing that the EPA failed to properly assess the environmental justice implications. Similar actions are underway in New Mexico.
