The US Environmental Protection Agency (EPA) has promulgated revisions to the National Ambient Air Quality Standards (NAAQS) for particulate matter (PM) [62 Federal Register, Number 138]. These revisions included two new standards for PM-2.5--PM with an aerodynamic diameter of 2.5 microns or less--and a revised PM-10 standard. PM-2.5 concentrations will be determined using a short-term, 24-hour average standard and an annual average standard. Although the implementation of these standards, in terms of determining compliance status and ultimately implementing control strategies, is many years away. It is clear this promulgation sets forth a very different direction on how sources may be controlled and how impacts will be determined.
