New Jersey Fines Microsoft-Linked AI Data Center $1.07 Million Over Illegal Generators

New Jersey environmental regulators have levied a $1.07 million fine against DataOne, the developer of a sprawling artificial-intelligence data center in Vineland tied to a $17 billion computing deal with Microsoft, after inspectors found the company had installed and run 62 large natural-gas generators for months without any of the air permits state law requires. The Department of Environmental Protection called it the largest enforcement action ever taken against a data center in New Jersey history, and one of the largest in the country against the industry.

The fine, announced by Governor Mikie Sherrill's administration on September 22, caps a monthslong dispute between a fast-growing hyperscale computing campus and the working-class South Jersey city that agreed to host it. It also arrives as data centers built to train and run AI systems multiply across the country, often outpacing the regulatory systems designed to oversee them.

A record fine for an unpermitted power plant

State inspectors visiting the 107-acre DataOne campus on July 29 found 62 stationary natural-gas generators, each a Caterpillar model rated at 1,982 kilowatts, running on the site. None of that equipment had been present during the DEP's previous inspection in December 2025. Combined, the generators produce roughly 123 megawatts of power — equipment New Jersey law requires a construction permit and operating certificate for at any size above 37 kilowatts, meaning each individual unit at the site exceeded the threshold by a factor of more than 50.

The DEP's order and penalty assessment accuses DataOne of violating the state's Air Pollution Control Act, which is designed to limit emissions of pollutants such as nitrogen oxides and carbon monoxide that are regulated because of their effects on respiratory health and regional smog formation. The agency's formal enforcement order directs DataOne to either immediately apply for the required permits or stop running the engines altogether.

"Today, we are taking action against Data One in Vineland for violating New Jersey pollution law with a $1.07 million fine, the largest in state history," Governor Sherrill said in a statement announcing the fine. DEP Commissioner Ed Potosnak was more pointed, saying the action "sends a clear message that these facilities will not be constructed or operated with impunity in this state."

A DataOne spokesperson, Naomi Race, said the company disagrees with what she called the "temporary generator determination" but confirmed it would apply for the permits the state says it lacks. She did not say whether DataOne intends to pay the penalty or to instead request a hearing, an option state rules give the company for 20 calendar days after the order was issued.

How the violations surfaced

The scale of the unpermitted equipment first became public in late August, when the nonprofit newsroom Floodlight and The Guardian published thermal drone footage showing at least 45 of the 62 generators running simultaneously at the still-under-construction site. Bruce Buckheit, a former head of air enforcement at the U.S. Environmental Protection Agency under two Republican administrations, told the outlets the operation appeared to "violate federal law" as well as state rules, and predicted the company would not stop "until they are issued a stop work order." DataOne did not respond to questions about the generators at the time, saying only that it "remains committed to meeting all applicable environmental and permitting requirements." Microsoft and Nebius Group, the Amsterdam-based company contracted to operate the site's computing infrastructure under the Microsoft deal, both declined to comment.

City officials in Vineland had already begun pushing back. In August, the city issued two separate stop-work orders against DataOne, one covering installation of a proposed 1.5 million-gallon liquefied natural gas storage tank and the other covering construction of Bloom Energy fuel cells meant eventually to replace the temporary generators. The city said DataOne had done both without the construction permits or planning board approvals required under its site plan, and warned of fines as steep as $2,000 per violation per day for continued noncompliance. A DataOne spokesperson characterized the stop-work notices as limited to "equipment placement work under the approved site plan" and said the company did not expect any delay to its construction schedule.

Noise, water and an uneasy bargain

For residents near the site, the generators and construction have been a daily presence well before regulators intervened. "The anxiety, just hearing that noise, it's driving me crazy, my wife crazy," Michael Gentile, who lives near the campus, said at a community meeting earlier this year. Neighbor Scott Montgomery described difficulty sleeping and said he could no longer sit in his backyard undisturbed. In March, roughly 100 people gathered for a rally in a Vineland park, organized in part by a local congressional candidate, to call for a moratorium on new data center construction statewide.

Other concerns center on water rather than noise. The site sits near the Kirkwood-Cohansey aquifer within the Pinelands National Reserve, and nearby farmers have questioned what a 300-to-350-megawatt campus will mean for groundwater levels used for irrigation and drinking wells. "Am I going to have to call my well guy? Am I gonna have to drill deeper?" farmer Michael Atkinson asked at the same meeting. Resident Zac Landicini, who has two young children, said his worry is less about water than what the generators themselves are putting into the air: "Emissions are concerning to me, especially with research into asthma and chronic health effects."

DataOne has countered those concerns by emphasizing the jobs and tax revenue the completed campus — ultimately envisioned at roughly 2.4 million square feet — is expected to generate, including more than 200 permanent positions and what the company says will make it one of the city's largest taxpayers. Cumberland County, where Vineland sits, has a median household income well below the state average, and local officials have generally supported the project even as they have moved to enforce permitting rules against it.

"We are putting power in the hands of the people and ensuring this industry works for us, on our terms — not theirs. Data centers will pay their fair share for energy, be accountable for their water and energy use, protect our environment, create good-paying union jobs, and invest in communities."

That quote, from Governor Sherrill's statement on the DataOne fine, echoes language she has used since unveiling her statewide data-center policy framework in May, a four-part plan that would require data center operators to pay for their own electricity and grid upgrades, publicly report their power and water consumption, negotiate formal community-benefit agreements with host towns, and rely on union labor. The plan was developed partly in response to complaints from ratepayer advocates that the cost of new electric generation and transmission needed to serve data centers was being quietly passed on to ordinary households' utility bills.

What happens next

DataOne's immediate options are to request a hearing to contest the DEP's findings or to submit permit applications for the generators, as it has told regulators it intends to do. The company has also said it still plans to transition its backup and primary power supply to Bloom Energy fuel cells, equipment for which it says it already holds the necessary approvals, though a company representative testified at a planning board meeting that those fuel cells could emit more than 2 billion pounds of carbon dioxide annually once the campus reaches full capacity. The Philadelphia Inquirer reported that no compliance deadline has yet been set for when the generators must either be permitted or shut down.

The dispute is likely to be watched well beyond South Jersey. Data centers built to meet surging demand for AI computing are being proposed and built at a pace that has repeatedly strained local zoning boards, utility regulators and, as in Vineland, state environmental permitting systems more accustomed to reviewing one power plant at a time than a cluster of dozens of generators appearing between inspections. Federal air-quality law, including the Clean Air Act's permitting requirements, generally defers initial enforcement of this kind to state agencies like New Jersey's DEP, leaving much of the practical oversight of the AI buildout to state regulators who, in this case, say they were caught off guard by what showed up between one inspection and the next.
