xAI Permit Sparks Legal Challenge Over Mississippi Plant
xAI, now owned by SpaceX, received a Prevention of Significant Deterioration (PSD) air permit from the Mississippi Department of Environmental Quality on March 10 to build a methane gas–fired power plant with 41 turbines in DeSoto County to power nearby data centers. Nonprofits including the NAACP, Young, Gifted & Green, and the Safe and Sound Coalition — represented by the Southern Environmental Law Center — petitioned the state to revoke the permit, arguing the authorization used inaccurate pollution estimates, failed to require the cleanest turbines or offsets, and excluded local stakeholders while the regulator rushed under xAI’s pressure. The plant would support xAI’s regional data-center buildout (including Colossus 2 in Memphis and a new Southaven facility). MDEQ said it received a request for an evidentiary hearing and xAI may join the proceeding. SpaceX acquired xAI in February in a transaction the article says values the combined entity at $1.25 trillion.
The story signals growing regulatory and community scrutiny of the energy and environmental impacts of AI data‑center buildouts; outcomes could affect siting, permitting timelines and operational requirements for heavy AI infrastructure providers.

Musk's xAI Gains Permit Amid Pollution Protests in Mississippi
Mississippi regulators approved a permit allowing Elon Musk’s xAI subsidiary MZX Tech LLC to build a power plant with 41 natural gas-burning turbines in Southaven to supply power to nearby data centers. The Mississippi Department of Environmental Quality voted to issue the permit despite opposition from the NAACP, the Southern Environmental Law Center (SELC) and local residents, who raised concerns about air and noise pollution, alleged underestimation of emissions (including nitrogen oxides, formaldehyde and particulates), and procedural issues. xAI — now owned by SpaceX after a February merger — has been operating temporary turbines at the site and plans an additional data center (dubbed Macrohardrr). NAACP and SELC said they will sue over xAI’s prior turbine use without federal permits; MDEQ said the draft permit met legal and technical requirements.
Elon Musk's xAI Faces Backlash Over Mississippi Power Plant Plans
Elon Musk’s xAI is pursuing permits to build a large natural-gas burning power plant in Southaven, Mississippi, adjacent to a planned data center. The Mississippi Department of Environmental Quality (MDEQ) scheduled its permit board meeting for the second Tuesday of the month — Election Day for the 2026 primaries — prompting the NAACP and local advocates to request a delay and a nearer hearing location; MDEQ denied the request. Community members and physicians have raised concerns about noise, air quality and public health after xAI operated multiple temporary gas turbines in the area. The NAACP filed a notice of intent to sue in February under the Clean Air Act. The article notes xAI’s recent merger with SpaceX (combined valuation cited at $1.25 trillion) and that tech firms including xAI have pledged at a White House meeting to supply their own power for facilities.
Elon Musk's xAI Faces Lawsuit Over Mississippi Pollution
Environmental and civil-rights groups — the Southern Environmental Law Center and Earthjustice, representing the NAACP — sent xAI and its subsidiary MZX Tech LLC a notice of intent to sue over emissions from dozens of natural gas-burning turbines at xAI’s Southaven, Mississippi facility. The groups allege the turbines require federal permits, violate the Clean Air Act and harm nearby communities. xAI, launched by Elon Musk in 2023 and recently merged into SpaceX, has operated similar turbines near Memphis at its Colossus 1 and Colossus 2 data centers. The EPA has clarified that such turbines cannot be classified as temporary non-road engines, and Mississippi officials will hold a public hearing on whether to permit 41 permanent turbines at Southaven. The dispute adds to broader scrutiny of xAI and its Grok chatbot amid multiple investigations and local complaints about air quality and noise.
