A message from our executive director:

“Thank you to everyone who spoke out,” Patrick Campbell said. “This may be a small win, but it sends a huge message: Our voices - especially when we raise them together - make a difference & can absolutely move the needle, even in this political environment.”

Now for something completely different - some GOOD news out of the EPA:

It signaled in a notice its intent to kill an interim final rule that would have delayed the full implementation of revised emissions standards for coke ovens.

#ICYMI: What’s going on at @ussteel.bsky.social’s Edgar Thomson facility? @inversion-doc.bsky.social has flagged myriad emissions events like this one from yesterday:

Inversion Documentary @inversion-doc.bsky.social · 6d

This morning there was a massive plume emitted from Nippon/US Steel's Edgar Thomson Mill in the greater Pittsburgh area. There was a massive spike in particles across the river about that time. The Allegheny County Health Dept needs to investigate. @breathe-project.bsky.social @gasp-pgh.bsky.social
