DEP Issues Air Permit For Largest Natural Gas Power Plant In US To Feed Proposed 3,200 Acre Homer City A.I. Data Center Campus In Indiana County

On November 19, the
Clean Air Council announced the Department of Environmental Protection issued an Air Quality Permit on Nov. 18 for the 4.5 GW natural gas power plant dedicated to providing power to feed the 3,200 acre Homer City A.I. Data Center Campus in Indiana County. 

The power plant would be the largest gas-fired power plant in the United States and generate enough electricity to power over 3 million homes.

The Council said the permit was issued over the objections of the public who submitted 571 comments identifying significant errors in the draft permit published for public review.

Local residents expressed concerns about increased air pollution, noise, odors, and compromised drinking water with minimal return benefits.

“This illegal permit is a death sentence for many of those who will breathe its toxic fumes in Indiana County and across the nation. Rushed-through, riddled with errors, and for what? It’s not to keep our lights on," said Alex Bomstein, Clean Air Council Executive Director.

"It’s for New York hedge fund investors and for tech billionaires to get rich off of technology designed to lay people off. Indiana County and Pennsylvania will rise up and defend our health and our lives from this dangerous, pointless plant.”

In its statement, the Council said, "Harrisburg has fallen in line across the aisle to support rapid buildout of A.I. infrastructure, even though the new power plants being proposed to run data centers in Pennsylvania are almost universally plants that would burn methane from local fracking wells.

"Science and experience tells us that this new fracking, and these new power plants, would pollute, sicken, and kill people in our region, exacerbate the climate crisis, and drive up the cost of electricity."

In comments submitted to DEP in September, the Clean Air Council, PennFuture, Sierra Club and Earthjustice said the project would emit three times more carbon dioxide than any other single facility in Pennsylvania, moving the state further away from meeting its climate targets under the state’s Climate Action Plan.  Read more here.

Signatories also raised concerns about DEP’s handling of the application and any other agency regulatory actions regarding the project.

DEP said it would act as a ‘concierge’ for companies behind the project, suggesting a troubling willingness to prioritize private industry over its responsibility to protect Pennsylvanians.
