Uncertainty Over Science, Improving Air Quality-Calls for Retaining Existing Standard

WASHINGTON (December 14, 2012) - The American Chemistry Council (ACC) today released the following statement regarding an announcement by the U.S. Environmental Protection Agency (EPA) lowering its PM2.5 standard:

"ACC is disappointed that EPA chose to lower the PM2.5 NAAQS to 12 µg/m 3 . Given the uncertainty of the particulate matter science, ACC had urged EPA to retain the current PM2.5 NAAQS, which was revised in 2006, and instead focus on implementing that standard. Air quality continues to improve under the existing standard. According to EPA's own data, the national average level of PM2.5 in the United States decreased by 27 percent between 2000 - 2010. 1

"ACC applauds EPA for including a grandfathering approach for facilities that have already submitted construction permits, and continues to urge EPA to develop implementation approaches that do not harm industry at a time of continuing economic recovery."
