In the latest step in its review of the National Ambient Air Quality Standards (NAAQS), the U.S. Environmental Protection Agency (EPA) established the foundation for unprecedented regulation of dust. According to EPA's Second Draft Policy Assessment for Particulate Matter (PM), issued late last week, EPA may consider regulating coarse PM at levels as low as 65-85 µg/m3, twice as stringent as the current standard.
"It would be virtually impossible for many critical U.S. industries to comply with this standard, even with use of best-management practices to control dust," said Tamara Thies, National Cattleman's Beef Association chief environmental counsel. "All of us certainly want healthy air for our communities, but this is nothing more than the everyday dust kicked up by a car driving down a dirt road, and it has long been found to be of no health concern at ambient levels."
