In 1997 then-US Environmental Protection Agency (EPA) Administrator Carol Browner adopted new National Ambient Air Quality Standards (NAAQS) for fine particulate matter (PM2.5). Browner recognized that 'there is uncertainty in the characterization of health effects attributable to exposure to ambient PM.' As a result, President Clinton promised to review the scientific basis for those standards prior to their implementation. Recently, before EPA has even promulgated rules concerning implementation of those standards, the agency proposed to revise those standards to make them significantly more stringent. Are the proposed revisions to the standards appropriate? The author argues. 41 refs.
