# Public hearing regarding the air quality permit for US Steel plant in Clairton.

Allegheny County public hearing on November 11, 2026, considered the draft air-quality installation permit for US Steel’s proposed hot-strip-mill investment at Edgar Thompson Works in the Mon Valley. Supporters—including company representatives, labor unions, business groups, and local officials—backed the project, citing a planned investment of nearly $3 billion, modernization and production growth, and projected employment and economic benefits. They said the permit would require modern emissions controls and a phased transition that permanently retires certain existing furnaces. No contract award, procurement action, vote, or permit decision was recorded.
