Millington’s Board of Mayor and Aldermen approved a six-month moratorium on certain new data center-related applications on October 12, 2026, according to Action News 5 and The Daily Memphian. The reported measure covers new applications for non-grid power generation, accessory computing and industrial-scale computing facilities; applications already accepted are exempt.
What Millington’s moratorium covers
The reports describe the moratorium as effective immediately and scheduled to expire on April 12, 2027, unless extended. Its terms apply to specified new applications, with a carve-out for applications already accepted.
What Memphis listed for October 20
The City of Memphis lists a council meeting for October 20, 2026, on its meeting page. In an interview published October 15, Tennessee state representative Justin J. Pearson said a moratorium vote was planned for October 20; that was Pearson’s account of the expected vote, separate from the city’s meeting listing (Democracy Now!).
What the air-quality research found
University of Memphis researchers writing in The Conversation say xAI’s Supercluster began operating on September 1, 2024. Their analysis estimated that turbine emissions added about 1% to fine particulate matter, on top of an already high background level. A separate comparison of satellite measurements from before and after operations began found no significant change in fine particulate matter. The two findings come from different methods, and the researchers describe them separately in their analysis.
The researchers also reported that permanent air-quality monitors were not operating in the closest southwest Memphis neighborhoods at the time of their work. In a separate two-day campaign in June 2025, an accredited lab’s equipment was not sensitive enough to detect trace benzene, toluene, ethylbenzene, xylenes or sulfur dioxide.
What the site footage shows
Oilfield Witness published optical gas imaging footage recorded by thermographer Sharon Wilson on May 13, 2025. It shows visible plumes around turbine equipment; the camera detects within a limited wavelength band of 3.2–3.4 μm.
