A federal judge has given the Environmental Protection Agency one week to set standards for fine particle pollution across the United States. These are the fine particles that come out of factories, power plants and automobiles.
Paul Cort is an attorney for nonprofit Earthjustice. He argued the case.
“This rule defines what it means to have clean air that’s safe to breathe,” Cort said. “And so by setting these standards, if an area has air that doesn’t meet these standards, then they have to develop a plan to reduce emissions that contribute to the pollution problem.”
