EPA proposes to weaken pollution controls on a Wyoming power plant
Official: Approval and Promulgation of Air Quality Implementation Plans; Wyoming; Regional Haze Federal Implementation Plan
Reading: The EPA proposes to withdraw a nitrogen oxide pollution-control requirement (BART closure determination) for Dave Johnston Unit 3, removing a previously mandated emission-reduction obligation.
This change would allow the plant to operate with less stringent pollution controls than previously required.
In clear language
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.
How does this affect you?
Pick the type of resident or organization you most identify with — we'll generate a plain-language breakdown of what changes for you and what you can do about it.
Who does this affect?
- Residents in Wyoming and neighboring states downwind of Dave Johnston Unit 3 who breathe air affected by nitrogen oxide pollution and regional haze
- Air quality and public health advocates working to reduce smog and visibility impairment in the West
- PacifiCorp and its shareholders, who would avoid expensive pollution-control retrofits or plant closure
What can you do?
- Submit a public comment during the federal notice-and-comment period (check the Federal Register for the deadline) opposing the withdrawal of the pollution-control requirement
- Contact your U.S. Senator or Representative to express concern about weakening regional haze protections

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.
