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.
