- Federal RegisterJul 15, 2026EPA approves Wisconsin's plan to reduce nitrogen oxide pollution from Oak Creek Power Plant
The EPA is approving Wisconsin's plan to set new, lower limits on nitrogen oxide emissions from the Oak Creek Power Plant. These new limits will require the plant to emit less pollution over time while still meeting federal air quality standards. This change helps improve air quality in the region and keeps the state in compliance with federal clean air rules.

The EPA is officially approving Michigan's plan to redesignate a polluted air area near St. Clair as having achieved healthy air quality for sulfur dioxide pollution. Michigan has also submitted and the EPA is approving a maintenance plan to keep that air quality from getting worse, including new emissions limits on a major power plant. This federal approval takes effect immediately.
- Federal RegisterJun 8, 2026EPA proposes to weaken pollution controls on a Wyoming power plant
The EPA is proposing to remove a requirement that a Wyoming coal power plant (Dave Johnston Unit 3) either close or install strict pollution-control equipment to reduce nitrogen oxide emissions that cause regional haze. The power company PacifiCorp asked the EPA to withdraw this requirement, and the EPA is agreeing to reconsider it. This change would allow the plant to operate with less stringent pollution controls than previously required.
