Michigan's plan to clean up regional haze gets federal approval

US environmental regulators have approved Michigan's plan to reduce regional haze, which is air pollution that reduces visibility. This means Michigan can continue with its long-term strategy to improve air quality in protected natural areas.

States must regularly update their plans to reduce regional haze, a type of air pollution that makes distant objects blurry. This approval means Michigan's current approach meets federal standards for the next phase of this ongoing effort. It ensures that the state's industrial and energy sectors will continue to operate under specific emissions limits designed to improve visibility in national parks and wilderness areas.
