Sierra Club Applauds EPA Progress to Improve Air Quality in National Parks

WASHINGTON - Yesterday, the U.S. Environmental Protection Agency (EPA) announced a proposal to update the Regional Haze Rule, a Clean Air Act protection intended to eliminate harmful air pollution in America’s national parks and wilderness areas. Haze, a mixture of smog and soot, is a byproduct of burning fossil fuels. Sources of haze pollution include coal-fired power plants, oil and gas operations, and vehicle emissions. Haze pollution in our national parks is a pervasive problem that harms visitor health, compromises scenic vistas, and can hinder local economies that depend on tourism.
