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 When permits are outdated, it gets harder to tell whether plants and mills are actually staying within limits meant to protect nearby neighborhoods.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.
