Mississippi's Department of Environmental Quality says SpaceXAI started construction on about 30 acres in Southaven before it had stormwater permits, Mississippi Today reported on November 6. The agency sent two notices of violation to MZX Tech LLC, a SpaceXAI subsidiary, on August 10. Each carries the maximum penalty of $25,000 for every day work continues without the permits.
SpaceXAI disclosed the possible fines to investors in October, saying they could reach $6.1 million. In an October 22 securities filing it said it "is cooperating with MDEQ and is in discussions to resolve the matters through a single agreed order." MDEQ declined to confirm the figure. At $25,000 a day, $6.1 million works out to about 244 days.
Inspectors visited on July 16. At a former training facility next to Horn Lake Creek, they wrote that "no steps have been taken to protect stormwater infrastructure at the site." At 2400 Stateline Road, the site of a planned $20 billion data center, they found no controls around storm inlets. Work there appeared to have started around the beginning of 2026. The property's last construction stormwater permit expired in 2023.
The air fight is separate. A federal judge found that MDEQ misread the Clean Air Act when it let SpaceXAI run 69 temporary gas turbines without a permit. The ruling came on a motion to dismiss an NAACP lawsuit. MDEQ says it is not a party and the case is subject to appeal.
The penalty is small next to a $20 billion project.
Permits are one of the few points where state officials can slow a build already under way. Like last week's local votes, they matter to developers more than the fines do.
Bottom Line
Fast AI builds are running ahead of their permits, and a $6.1 million fine does not change the math on a $20 billion campus. Residents near these sites should watch state permit dockets, where violations surface while there is still time to object.
