U.S. Steel Class Action

On May 12, 2023, a Pennsylvania court authorized six Mon Valley residents to sue U.S. Steel on behalf of 123,000 neighbors over pollution caused by the Christmas Eve 2018 fire at the Clairton Mill.

If you lived in one of the 22 Mon Valley communities shown in the map below, you may be in the class action.

As of 2025, we (as the Class Action counsel) are deep in document discovery, depositions, and work with experts preparing the case for trial and hoping for a trial date in early 2026.

Polluting U.S. Steel

Lawsuit over Christmas Eve fire at U.S. Steel’s Clairton Coke Works granted class action status

Our Case

On Christmas Eve of 2018, a catastrophic fire knocked out the pollution controls at U.S. Steel’s Clairton Plant. U.S. Steel continued production for months—even though it had no way to clean the sulfur out of its coke gas emissions.

Air pollution spiked in the Mon Valley and U.S. Steel’s neighbors suffered noxious odors, burning eyes, nose, and throat, difficulty breathing, headaches, and nausea.

Now the neighbors are fighting back in a class action lawsuit called Hernandez v. U.S. Steel.

You Can Help

Every Mon Valley resident has a story about the pollution that year. Every story makes a difference.

If you lived in the class area at the time of the fire, we’d like to hear your story.
