"The Obama administration on Friday scored its third major legal victory on air pollution in less than month when a federal appeals court rejected an industry challenge to its latest health standards for fine particulate matter, or soot.

The unanimous ruling by a three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit found the U.S. Environmental Protection Agency was within its discretion in 2012 when it tightened limits on lung-damaging soot.

The National Association of Manufacturers filed a legal challenge to the regulations last year, saying the agency had overreached and would crush businesses' plans for growth."
