The U.S. Environmental Protection Agency is holding a series of meetings this week on proposed pollution controls for a coal-fired power plant on the Navajo Nation.
The first of four meetings is set for Tuesday in the Navajo community of Shiprock, N.M. Other meetings are scheduled in Fruitland and Farmington in northwestern New Mexico and Durango, Colo.
The EPA is asking the public to weigh in on a plan to cut nitrogen oxides at the Four Corners Power Plant by 87 percent under a regional haze rule.
The 45-year-old power plant is the largest single source of nitrogen oxide emissions in the United States and has been under increased scrutiny over other emissions as well.
Arizona Public Service Co., a subsidiary of Pinnacle West Capital Corp., operates the plant.
