The sweeping vistas at national parks and monuments throughout the West are more frequently becoming obscured by haze, according to a report released Tuesday by Environmental Defense.
The report by the national nonprofit group says air quality across the region is declining, with increasing ozone and haze. It also says several new coal-fired power plants and increased oil and gas development could have an adverse impact on air quality.
"It's a classic good news-bad news story," said Dr. Jana Milford, a Boulder-based senior scientist with Environmental Defense. "The bad news is that we're seeing some disturbing trends." The good news, she said, is that new rules curbing industrial emissions may reduce haze.
Under a court-ordered deadline, the result of an Environmental Defense lawsuit, the U.S. Environmental Protection Agency is expected today to issue cleanup guidelines for power plants, refineries and other older industrial sources. The new rules - called "Best Available Retrofit Technology" - require those facilities to make upgrades and could affect about 16 plants in Colorado. Among them: the Cemex cement plant in Lyons, the Valero refinery in Denver and several Xcel power plants throughout the state."
