Major pollution spike this AM and stench as expected. Plume(s) from Edgar Thomson appear to align with a significant rise in PM2.5 levels nearby. Video starts around 4:17am. (Thx to @breathe-project.bsky.social and CMU CREATE Lab for BreatheCam footage) #Stinkburgh #Pittsburgh #Airquality
🚨#Stinkburgh Alert! The forecast looks like we might have stench in Pittsburgh overnight. Stay alert and submit smell complaints to SmellPGH app and ACHD.
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 @breathe-project.bsky.social and CMU CREATE Lab for BreatheCam footage)
Morning! Here is today’s air quality forecast for Allegheny County:
Economist and author, Chris Briem, examines the fraught relationship between the steel industry and the Mon Valley. "Remaining focused on the past will only defer change that will eventually come..." #Pittsburgh www.publicsource.org/us-steel-pur...
One year in, Nippon’s purchase of U.S. Steel has changed much — but not the Mon Valley
"Unchanged, so far, is the region’s failure across so many levels to address the economic collapse of the communities of the Mon Valley. Now four decades since the contraction of the regional steel in...

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 CMU CREATE Lab and @breathe-project.bsky.social for BreatheCam footage.) 🧵1/2
🚨#Stinkburgh Alert! Conditions appear to be ripe for overnight/AM elevated pollution and stench. Stay alert, filter your air if you can, and submit smell complaints to the ACHD and SmellPGH app. #AirQuality
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 for BreatheCam footage)🧵
Yesterday at Nippon/US Steel's Edgar Thomson Plant. Plumes coming out of multiple stacks. #AirQuality #Pittsburgh (Thx to @breathe-project.bsky.social and CMU CREATE Lab for BreatheCam footage.)
Lots going on at US Steel's Edgar Thomson plant this evening. #Pittsburgh #AirQuality (Thx to @breathe-project.bsky.social and CMU CREATE Lab for BreatheCam footage)
🤮 Goodness. I hope the workers in/around that building are wearing respiratory protection. #AirQuality #Pittsburgh (Thx to the @breathe-project.bsky.social and CMU CREATE Lab for BreatheCam footage showing U.S. Steel's Edgar Thomson Mill facility emitting a cloud of something TODAY 5/30/26.)

What is this? Nearly an hour of emissions from US Steel Edgar Thomson Plant in Braddock yesterday. #airquality #Pittsburgh (Thx to @breathe-project.bsky.social & CMU CREATE Lab for BreatheCam footage)
Strong inversion forecasted for tonight. Slow winds from the south. Likely stench in Pittsburgh overnight. Stay alert and submit smell complaints to SmellPGH app and ACHD website! #Airquality #Pittsburgh
#Stinkburgh Alert! Likely stench and elevated pollution tonight and early next week. Send smell complaints to SmellPGH app and ACHD. This video is this AM at Edgar Thomson mill -- a hazy plume emerging this building. Thx to @breathe-project.bsky.social & CMU CREATE Lab for BreatheCam footage.
I spotted seven major plumes coming out of US Steel's Edgar Thomson Plant in a single day. TODAY. 🤢 Thx to @breathe-project.bsky.social and CMU CREATE Lab for the BreatheCam footage. #airquality #Pittsburgh
Weak inversion in the morning, plus slow winds from the south-ish overnight could elevate pollution a bit. Stay alert! @gasp-pgh.bsky.social @breathe-project.bsky.social
Group Against Smog and Pollution (GASP)@gasp-pgh.bsky.social · 4mo agoMorning! Here is today’s air quality forecast for Allegheny County:
🚨Stinkburgh Alert! Likely stench and elevated #air pollution tomorrow in #Pittsburgh. Stay alert and report smells to ACHD and SmellPGH app if you smell it! @gasp-pgh.bsky.social @breathe-project.bsky.social
We've had elevated H2S and large numbers of SmellPGH reports the last couple days in Allegheny County. Not cool. We've hit twice the number of 24-hr exceedances of the H2S standard compared to this time last year. It really stinks around here. @gasp-pgh.bsky.social @breathe-project.bsky.social
🚨‼️#Stinkburgh Alert! Strong inversion forecasted for tomorrow morning. Wind from the south. I anticipate that some areas will experience elevated pollution and stench overnight and tomorrow morning. Stay alert. Report smells via ACHD and SmellPGH if you smell something.
🚨🚨#Stinkburgh Alert‼️🤮 It's just awful outside. Loads of SmellPGH reports. Elevated VOC's, particles, and H2S pollution. The foul sulfur odor woke me up early this morning. Submit complaints to ACHD & SmellPGH app if you smell it. #AirQuality @gasp-pgh.bsky.social @breathe-project.bsky.social
‼️#Stinkburgh Alert! ACHD is already reporting a Mon Valley Air Pollution Warning. Particles, VOC’s, and H2S levels are high. Elevated pollution expected into tomorrow, too. Please be careful out there and report smells to the ACHD and SmellPGH if you encounter them.
It was so bad this morning! Thanks to GASP for this write-up! And there is a link lower in the post that explains how to submit an air quality complaint. If you are annoyed by the pollution and/or smell, please submit a complaint to SmellPGH AND the ACHD GovQA system!
Group Against Smog and Pollution (GASP)@gasp-pgh.bsky.social · 7mo agoYinz smell that?! That tell-tale stench of rotten eggs? Culprit could be concentrations of Hydrogen sulfide (or H2S for short) that are sky-high in & around the Mon Valley. But the exceedances don’t tell the whole story. There were also CRAZY HIGH H2S spikes. www.gasp-pgh.org/smell-that-f...
