Two separate plume incidents at US Steel's Edgar Thomson Plant in Braddock, including dark grey material. US Steel wants to⬆️pollution from from ET via the new hot strip mill.🤮We have to require them to do better. (Thx to @BreatheProject and @cmucreatelab for BreatheCam footage)

Three more plumes at Nippon/US Steel's Edgar Thomson Plant. And USS wants to *increase* pollution at the plant with new equipment powered by fossil fuels during a climate emergency. (Thx to @cmucreatelab and @BreatheProject for BreatheCam footage.) đź§µ1/2

Notice a funny smell outside today? If you're anywhere near the Edgar Thomson Works, it's not your imagination — and the data backs you up. SmellPGH and Allegheny County's air quality monitors are both showing a spike right now.

Major pollution and complaints this AM. Also a plume at US Steel's Edgar Thomson Plant feeding right into a low air mass ~8am. Spike in PM2.5 via PurpleAir monitor, elevated H2S, and many SmellPGH complaints. #AirQuality #Pittsburgh (Thx to @BreatheProject & @cmucreatelab)đź§µ

And SmellPGH complaints match the pattern pretty well (visual also shows wind direction this AM): [complaint triangles show pattern emerging around Swissvale and spreading out NW from there]

And look at what community members have to say about the smells via SmellPGH (thx @cmucreatelab for that app!) "eggy, industrial" and "burnt plastic" "rotten eggs" "sulfur" "coal smoke and dust" #AirQuality #Pittsburgh

🤮Goodness. I hope the workers in/around that building are wearing respiratory protection. #AirQuality #Pittsburgh (Thx to the @BreatheProject and @cmucreatelab for BreatheCam footage showing U.S. Steel's Edgar Thomson Mill facility emitting a cloud of something TODAY 5/30/26.)
