NAACP Lawsuit Threat Over Operating Gas Turbines Without Permits

The civil rights group has issued an NAACP lawsuit threat against xAI, alleging the company began illegally installing and then operating 27 gas turbines at a site in Southaven, Mississippi to power Colossus II, which sits across the state line in Memphis 1

. The NAACP, acting on behalf of the largely African American local community living near the existing Colossus I facility in Memphis, Tennessee, accuses xAI of violating the Clean Air Act by failing to obtain necessary preconstruction permits or operating permits 1

. Under the Clean Air Act, plaintiffs must signal their intent to sue 60 days in advance 1

Air Quality Issues and Environmental Concerns Escalate

The NAACP warned in its letter that pollution from these turbines is worsening and will continue to worsen the already poor air quality in Southaven, Mississippi and the Memphis metropolitan area 1

. The gas turbines have the potential to emit significant amounts of smog-forming nitrogen oxides (NOx), exceeding the Clean Air Act's "major source" threshold, along with other pollutants including fine particulate matter and carcinogenic formaldehyde 1

. This isn't the first time xAI has faced legal challenges over unpermitted turbines. After the Southern Environmental Law Center filed an intent to sue xAI in 2024 for installing 35 non-permitted turbines at its Colossus I site, the company removed 20 turbines and obtained permits for the remaining 15 1

Potential Consequences and What's Next

Environmental lawsuits by the NAACP and SELC over unpermitted gas turbine installation could lead to project delays, mandatory removal of turbines, fines, or stricter regulations for the Colossus II data center 2

2

. Local community and NAACP opposition, citing health and environmental harms, could increase regulatory scrutiny and create obstacles that may delay or alter xAI's expansion plans 2

2

. The company faces challenges obtaining air pollution permits under the Clean Air Act, with heightened scrutiny from state regulators due to lawsuits citing possible violations and local environmental concerns 2
