State and county regulators are locked in a slow-motion fight over overdue air-quality permits, leaving some of Allegheny County’s biggest polluters running on expired or missing paperwork. Environmental watchdogs say this is not just a filing issue. When permits are outdated, it gets harder to tell whether plants and mills are actually staying within limits meant to protect nearby neighborhoods.
The clash is putting fresh heat on questions that are anything but bureaucratic: how aggressively agencies enforce the rules, how transparent they are with the public, and who is supposed to pick up the tab to speed reviews.
Which permits are late
Watchdog groups tracking the numbers say Title V operating-permit applications for some of the region’s biggest polluters are sitting past the 18-month review window required by federal and state law. As TribLIVE reported, advocates have flagged at least 15 overdue or problematic permits across the state Department of Environmental Protection regional offices, pointing to facilities tied to the Shell ethane cracker in Potter Township and a Tenaska power plant.
The Group Against Smog and Pollution’s own permit clearinghouse adds more trouble spots to the list, including an ATI steel-rolling facility with a permit more than a decade overdue and several cases in the Southwest Regional Office that have lingered past statutory timelines. Taken together, they sketch out a backlog that advocacy groups say has real consequences for air quality.
State says it cleared the backlog
The Pennsylvania Department of Environmental Protection insists the broader story looks very different when you zoom out from individual cases to its overall reforms. In a January news release, the agency said it reviewed and acted on more than 40,000 permit applications in 2025 and cut what it called a historic backlog from roughly 2,400 applications in November 2023 to zero by October 2025, thanks to a new SPEED program and a Bureau of Permitting Coordination.
DEP also said it carried out more than 116,000 inspections in 2025 and that inspectors routinely visit facilities to verify compliance, according to the Pennsylvania Department of Environmental Protection. State officials maintain that oversight on the ground has continued even when paperwork has lagged.
Watchdogs push back
Local clean-air advocates counter that statewide statistics do not change the fact that some specific, high-risk facilities are still operating without current permits or have renewals stuck in limbo for years. “We’re talking about facilities that can put 25 tons of pollution out annually,” Patrick Campbell of the Group Against Smog and Pollution told TribLIVE, adding that some operators “aren’t following their own rules.”
For residents living near plants and mills, those delays translate into a steady uncertainty about what they are breathing and how tightly agencies can actually crack down when problems crop up.
County response and funding moves
Allegheny County officials have tried to tackle their side of the problem by changing how the health department is funded. Last November, the County Council voted to raise permit fees for larger emitters in an effort to give the Allegheny County Health Department more money for reviews and enforcement, WESA reported.
Even so, county records show a noticeable backlog remains while staff work through renewals and public comments. ACHD continues to roll out draft permits and move them through the public-comment process, but the queue is still there. Officials from both the county and the state say the fee changes and DEP’s reforms should help turn permits around faster. Advocates say they want more than assurances. They are asking for firm deadlines and clear, public tracking of each permit's status.
Legal context
Under Title V of the Clean Air Act and matching Pennsylvania rules, agencies are supposed to complete permit reviews within an 18-month window. Federal law also allows facilities that submit a complete application to keep operating while the review is underway, a legal gap that sometimes sets the stage for court fights.
Groups like the Group Against Smog and Pollution argue that this “operate-while-pending” provision takes away some of the immediate pressure on agencies to hit those deadlines. That has led advocates in the past to ask the U.S. Environmental Protection Agency to step in or to go to court for schedules that are enforceable by a judge. Environmental organizations have previously won consent decrees and other agreements that locked in timelines for long-delayed permits.
GASP and related advocacy filings lay out that history and the strategies activists have used. The Environmental Integrity Project has documented earlier settlements that forced Allegheny County to meet specific permit deadlines.
For now, residents, local officials, and environmental groups say they will be glued to DEP’s permit docket and the ACHD public-comment calendar, watching for draft permits that finally move to final action. State and county leaders say the reforms will continue and that inspections and compliance checks remain routine while the paperwork catches up.
