ELR Citation: 56 ELR 20096
No(s). 25-1163 (D.C. Cir. Jul 17, 2026)

The D.C. Circuit denied environmental groups' petition to review an EPA rule that extended deadlines for steel mills to comply with certain hazardous emission standards. The groups argued the revised compliance deadlines were inconsistent with the CAA and unreasonable. The appellate court concluded the extensions were consistent with the CAA, and that EPA reasonably explained that the extensions were necessary because problems with the standards made compliance by the original deadlines technologically infeasible. It denied the petition.
