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

US environmental regulators are approving Alaska's plan to reduce regional haze. This means Alaska can move forward with its own approach to meet federal clean air standards.

States must submit plans to the US environmental regulators to reduce haze, which is air pollution that reduces visibility over large areas. This approval means Alaska's specific strategy, which includes measures for industrial facilities and addressing emissions from sources like wildfires, is now officially recognized. It sets a precedent for how other states might approach their own regional haze plans, especially those with unique environmental challenges.
