“Datacenter developers accused of skirting key US pollution rules”
What actually happened
Environmental advocates and attorneys allege that data center developers, including Amazon and Duke Energy in North Carolina and BorderPlex in New Mexico, have split single projects into multiple "minor" air permits to avoid the more stringent "major source" review required under the Clean Air Act. In North Carolina, Amazon and utility giant Duke Energy are installing 649 diesel generators to back up a new hyperscale center, and submitted two permits, avoiding a major review despite being in a low income area that already suffers from high levels of air pollution. Amazon disputes this characterization, saying its permit reflects genuine separate ownership.
Key facts
- North Carolina regulators approved the split permits: "Amazon's permit covers 592 emergency generators, including 588 critical backup generators and four ancillary generators. Duke Energy received a separate permit for 57 temporary generators."
- SELC's formal comments state the Duke permit alone would allow "up to 39.9 tons per year of NOX and 99.9 tons per year of CO," and the group is urging regulators to treat all 649 generators as one major source.
- SELC has since escalated: "by splitting the 600-plus diesel generators into two separate air quality permits, Duke and Amazon are 'illegally evading requirements of the Clean Air Act.'"
- An independent academic review found the split "conceals the magnitude" of pollution: an NC State professor said splitting the applications "conceals the magnitude" of the combined pollution.
- In New Mexico, the article reports Project Jupiter's developers proposed 20.2 to 24.2 tons of hazardous air pollution from each of two "microgrids," together approaching 44 tons versus the 25-ton federal minor-permit threshold, before withdrawing the application amid community pushback.
- Amazon's on-record defence is included: the company says its North Carolina permit "appropriately applied for and obtained" and reflects "actual ownership and operational structure."
What to watch for
Watch the outcome of SELC's petitions to North Carolina's Office of Administrative Hearings seeking to revoke the Amazon and Duke permits; a ruling either way will settle whether "common control" applied. Also watch whether New Mexico's Project Jupiter resurfaces with a single major-source application after its state supreme court delay, which would validate advocates' framing.
