The Shelby County Health Department this week approved a permit for Elon Musk’s xAI data center to continue operating its mobile gas turbines in Memphis, which power the Grok chatbot.
The decision follows hundreds of citizen input and the imminent filing of a lawsuit alleging noncompliance with clean air regulations. However, despite pressure from residents and environmental organizations, the local government has allowed the operation of 15 turbines at the former factory site until at least 2027.
This permit, initially reported by the Daily Memphis, comes after months of tension. In June, the local Chamber of Commerce confirmed that xAI had chosen the site for its Colossus supercomputer, assembled in just 122 days. To speed up construction, the company installed several gas-fired units, surprisingly quickly repurposing the space.
Permit sparks controversy
The predominantly African-American community of Boxtown, which has a history of respiratory conditions, denounced the risk of harmful emissions from the xAI machines.
Experts point out that gas turbines release nitrogen oxides, elements that contribute to smog formation. In fact, Memphis has one of the highest rates of childhood asthma in Tennessee.
KeShaun Pearson, spokesperson for the Memphis Pollution Initiative, expressed dismay at the permit: “It’s outrageous to see the voices of more than a thousand people who were calling for stricter regulations being ignored,” he said.
Federal regulations require a specific permit (Prevention of Significant Deterioration) for large emitters, but local officials argued that the turbines are not permanent and therefore did not require such a permit until they applied retroactively in January.
Turbines and air quality
Meanwhile, the NAACP and the Southern Environmental Law Center (SELC) announced their intention to sue xAI for violating environmental laws.
Amanda Garcia, an attorney for SELC, criticized the county’s decision: “Instead of addressing Boxtown’s historical shortcomings, it opens the door to a new source of pollution without adequate controls,” she said in a statement.
The controversy escalated when Mayor Paul Young claimed the facility was operating 21 turbines, but aerial photographs taken in April revealed up to 35 active units. xAI did not immediately respond to media requests for the exact number of machines in use, and Shelby County did not immediately provide clarification.
Sharon Wilson, a thermographer specializing in optical gas imaging, traveled from Texas to document the emission of invisible gases. Using a state-of-the-art camera, she detected a dense mass of pollutant that, she said, exceeded any observed at energy facilities. “I thought I would see the usual level of damage from a power plant, but it was much worse than I had anticipated,” he said.
