It's the third notable environmental court win in a month, upholding the EPA's right to clamp down on particulates that cause heart attacks and asthma.
The U.S. Court of Appeals for the D.C. Circuit ruled that the EPA acted properly in 2012 when it further restricted allowable soot emissions. It was the Obama administration’s third big environmental legal victory in a month. And experts say that bodes well for the administration’s efforts to clamp down on climate-changing emissions from power plants. The L.A. Times explains:
The 11-page decision rejected industry complaints and found that the EPA had acted reasonably and within its bounds when it adopted stricter nationwide standards for fine particulate matter. The tiny, chemical-laden particles and liquid droplets are emitted by power plants, diesel trucks, refineries and factories. They lodge deep in the lungs when inhaled and are linked to heart and lung disease, respiratory illnesses and premature deaths. …
Based on scientific studies, the EPA tightened annual limits on fine particle pollution from 15 micrograms per cubic meter to 12 micrograms per cubic meter and set new requirements for dozens of major cities to install air quality monitors to test for the pollutants near busy roadways.
