ACHD Statement on American Lung Association's report which references Allegheny County

PITTSBURGH – We respectfully acknowledge the American Lung Association’s continued advocacy for clean air and their recent assessment of Allegheny County's air quality. However, we believe that the report’s conclusion does not fully reflect the substantial and measurable progress made in our region — nor the robust systems in place to protect the health and well-being of the more than 1.2 million residents who call Allegheny County home.

Over the past several years, the Allegheny County Health Department’s Air Quality Program has worked diligently to strengthen enforcement, modernize infrastructure, and ensure compliance with environmental regulations. As reflected in our 2023 Air Quality Annual Report, Allegheny County met all National Ambient Air Quality Standards (NAAQS) as determined by the U.S. Environmental Protection Agency — including for PM2.5, a key pollutant often cited in public health analyses. In fact, this marks the third consecutive year of achieving these federal standards.

Our air monitoring network is among the most comprehensive in the nation, comprising nine strategically placed sites across the county. These stations provide detailed and transparent data that is reviewed and accepted by the EPA. In 2023, Allegheny County experienced no exceedances of the standards for nitrogen dioxide (NO₂), carbon monoxide (CO), lead (Pb), or particulate matter 10 (PM10). And while we saw limited exceedances in ozone and hydrogen sulfide, the context is important — including the outsized impact of Canadian wildfire smoke and climate-driven events beyond our control.

We also want to take this moment to acknowledge the dedicated professionals on our Air Quality Team, who are on the front lines every day — investigating complaints, monitoring emissions, and pursuing enforcement to ensure regulated sources remain within their permit limits. Their expertise and commitment are vital to our continued progress.

That said, we are not declaring victory. We know there is more to do, particularly in communities historically burdened by industrial emissions. Exceedances, even when infrequent, are reminders of the importance of vigilance, accountability, and continuous improvement. As public health professionals, we share the same goal as the American Lung Association: a future where everyone breathes easier.

We remain committed to the progress championed by the Clean Air Act, and to working with local, state, and federal partners to confront new and ongoing challenges — including the growing influence of climate change on regional air quality.

We invite the public and our partners to engage with the data, review our annual reports, and join us in this important work. Because clean air isn’t just a destination — it’s a journey we take together.
