Why It Matters
Mississippi environmental regulators allege SpaceXAI began construction for a Southaven data center without required water permits. The company has disclosed potential fines of up to $6.1 million to investors.
What Happened
MZX Tech LLC requested construction permits from the Mississippi Department of Environmental Quality for a Southaven site that includes a power plant and land designated for the MACROHARDRR data center facility.
MDEQ records indicate construction had started across about 30 acres. The agency confirmed the alleged violations during a July 16 inspection and sent MZX Tech two notices of violation on Aug. 10.
Each notice carries a maximum statutory penalty of $25,000 for every day construction continues without the required permits. MDEQ has not confirmed whether the $6.1 million figure disclosed by SpaceXAI accurately reflects the potential penalties.
MDEQ also reported environmental-control deficiencies at a former Southaven training facility near Horn Lake Creek. The agency found no stormwater-infrastructure protections there and insufficient measures to control fugitive dust. At 2400 Stateline Road, inspectors found no controls around storm inlets; the property’s last construction stormwater permit expired in 2023.
SpaceXAI said it is cooperating with MDEQ and discussing one agreed order with the agency.
By the Numbers
$6.1 million — potential maximum fines SpaceXAI announced to investors
$25,000 — maximum statutory penalty for each day construction continues without required permits
30 acres — approximate area where MDEQ records indicate construction had begun
69 — temporary natural gas turbines operated without a permit, according to a federal court ruling
$20 billion — value of the planned MACROHARDRR data center facility
Zoom Out
The permitting dispute follows a separate federal court ruling involving the facility’s temporary natural gas generators. Judge Debra Brown found that MDEQ had misinterpreted federal clean-air statutes by allowing 69 turbines to operate without a permit.
Brown also ruled that a mobile-source exemption could not apply to the generators. MDEQ had previously told SpaceXAI it could operate them under that exemption.
Brown denied a motion to dismiss the NAACP’s April lawsuit against the data center company. MDEQ said the federal order is not binding on the agency and remains subject to appeal.
“MDEQ is aware of the Court’s order and takes seriously all opinions by a federal court,” agency spokesperson Jan Schaefer said.
What’s Next
SpaceXAI and MDEQ are discussing a single agreed order addressing the alleged violations. MDEQ also scheduled a public hearing for Tuesday, Feb. 17, 2026, at Northwest Mississippi Community College in Southaven.
